The present invention also is directed to methods of treatment for mitochondrial disorders, metabolic conditions, diabetic conditions, and cardiovascular conditions, by administration of compositions of the present disclosure.
This application is a Divisional of U.S. Nonprovisional patent application Ser. No. 16/665,795, filed Oct. 28, 2019, which is a Continuation of International Patent Application No. PCT/US2018/064610, filed Dec. 7, 2018, which claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Patent Application No. 62/595,909, filed Dec. 7, 2017, the entire contents of which are incorporated herein by reference.
FIELD OF THE INVENTIONThe present invention relates to stable therapeutic compositions comprising pharmaceutical grade acids and pH buffering agents. The present invention also is directed to methods of treatment for conditions and disorders characterized by mitochondrial dysfunction, metabolic conditions, diabetic conditions, cardiovascular conditions, and bone and tissue modeling dysfunction, comprising administration of compositions of the present disclosure.
BACKGROUND OF THE INVENTIONHomeostasis is the ability of an organism to maintain a condition of equilibrium or stability within its internal environment, particularly when faced with external changes. Some examples of homeostatically-controlled systems in humans include the regulation of a constant body temperature, blood glucose levels, and extracellular ionic species concentrations. Acid-base homeostasis relates to the proper balance of acids and bases in extracellular fluids, i.e., the pH of the extracellular fluid. In humans, the pH of plasma is approximately 7.4, and is tightly maintained around that value by three interconnected control systems: 1) buffering agents, including bicarbonate, phosphate, and proteins, 2) the respiratory system, which impacts the partial pressure of carbon dioxide in blood plasma, and 3) the renal system, which excretes waste acids and bases. Acid homeostasis is also influenced by metabolic load, which serves as a primary source of acid in the body. For instance, a high glucose diet can increase total acid burden from metabolic sources, to place a bigger burden on acid homeostasis control mechanisms.
Inefficiencies in these control systems and factors, which increase acid, such as from metabolic sources, may gradually result in unstable internal environments that increase the risk of illness, or exacerbate existing conditions. These inefficiencies may be caused by natural aging processes or may be self-inflicted through various lifestyle choices. For example, a high-glucose diet and a sedentary lifestyle can lead, over time, to the development of insulin insensitivity and type 2 diabetes. Diabetes is associated with other conditions such as obesity, hypertension, hyperlipidemia, fatty liver disease, nephropathy, neuropathy, renal failure, retinopathy, diabetic ulcer, cataracts, insulin resistance syndrome, cachexia, diabetic foot ulcers and diabetic leg ulcers.
Cardiovascular diseases may also be caused by a poor diet and sedentary lifestyle, and include coronary heart disease (heart attacks), cerebrovascular disease, raised blood pressure (hypertension), peripheral artery disease, rheumatic heart disease, congenital heart disease and heart failure. Such dysfunctional conditions of the heart, arteries, and veins impair the supply of oxygen to vital life-sustaining organs, including the brain and the heart itself.
Heart attacks and strokes are mainly caused by a blockage in the inner walls of the blood vessels that prevents blood from flowing to the heart or the brain. Arteriosclerosis (also called atherosclerosis) is a condition involving excess buildup of fat or plaque deposits, respectively, that cause narrowing of the veins that supply oxygenated blood to the tissues. In arteries serving the heart for instance, this may lead to ischemic heart disease, an obstruction of blood flow to the heart. Excess fat or plaque buildup may also cause high blood pressure (hypertension), a disease known as “The Silent Killer” because the first warning sign is an angina attack, a deadly heart attack or a stroke. Kidney disorders, obesity, diabetes, smoking, excess alcohol, stress, and thyroid and adrenal gland problems can also exacerbate a high blood pressure condition.
These conditions and many others are brought on by inefficient, ineffective, or over-stressed homeostatic processes. Over time, the resulting imbalances cause damage at the cellular and intracellular level. Often the mechanisms for cellular repair are so compromised that the cells cannot recover, or the mechanisms that cause the damage simply overwhelm the cell. The clinical significance of the damage generated in living cells is manifested in a diseased cell, or symptoms of an underlying condition. It would be beneficial to develop methods to facilitate the inhibition of cellular damage or boost recovery. The presently disclosed subject matter addresses, in whole or in part, these and other needs in the art.

The details of one or more embodiments of the invention are set forth in the description below. Other features, objectives, and advantages of the invention will be apparent from the description and from the claims.
The accompanying drawings, which are incorporated herein and constitute part of this specification, illustrate the presently preferred embodiments of the invention, and, together with the general description above and the detailed description given below, serve to explain the features of the invention. In the drawings:
The present invention will now be described more fully hereinafter. However, many modifications and other embodiments of the present invention set forth herein, e.g., for the amelioration and/or treatment of specific conditions and disease states, will come to mind to one skilled in the art to which the invention pertains having the benefit of the teachings presented in the foregoing descriptions. Therefore, it is to be understood that the present invention is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims.
As used herein, the term “mammal” refers to humans as well as all other mammalian animals. As used herein, the term “mammal” includes a “subject” or “patient” and refers to a warm-blooded animal. It is understood that guinea pigs, dogs, cats, rats, mice, horses, goats, cattle, sheep, zoo animals, livestock, primates, and humans are all examples of animals within the scope of the meaning of the term. As used herein, “a mammal in need thereof” may be a subject who could have been, but is not required to have been, diagnosed as suffering from the condition intended to be treated. In one aspect, the present method is directed to conditions that are noticeable to the subject and the subject wishes to treat or ameliorate the condition without a formal diagnosis. Alternatively, a mammal in need thereof is one who has been diagnosed as having a condition and is in need of specific treatment. In other embodiments, a mammal may also be functioning normally relative to common standards but electively seeks to enhance performance for various purposes, such as for enhanced mental acuity or athletic interests.
The terms “subject” and “patient” are used interchangeably, and are meant to refer to any mammal, including humans, that has, or is at risk of developing, a dysfunctional cardiovascular condition. The subject or patient is typically human, however, other suitable subjects or patients include, but are not limited to, laboratory animals, such as mouse, rat, rabbit, or guinea pig, farm animals and domestic animals or pets. Non-human primates are also included.
As used herein, a “therapeutically effective amount” is an amount effective to elicit a cellular response that is clinically significant.
As used herein, the terms “treating” and “ameliorating” are intended to refer to all processes wherein there may be a slowing, interrupting, arresting, or stopping of the progression of the condition or symptoms, and does not necessarily indicate a total elimination of the underlying condition. The terms also encompass the administration of a pharmaceutical grade, physiological component, or natural physiological buffer composition wherein the mammal has a condition or symptom or a predisposition towards a condition or symptom, where the purpose is to cure, heal, alleviate, relieve, alter, improve or affect the condition or symptom or the predisposition to the same. Also contemplated is preventing the condition or symptom or the predisposition to the same, by prophylactically administering a pharmaceutical grade buffer composition as described herein.
As used herein, the term “pharmaceutical grade” means that certain specified biologically active and/or inactive components in the drug must be within certain specified absolute and/or relative concentration, purity and/or toxicity limits and/or that the components must exhibit certain activity levels, as measured by a given bioactivity assay. Further, a “pharmaceutical grade compound” includes any active or inactive drug, biologic or reagent, for which a chemical purity standard has been established by a recognized national or regional pharmacopeia (e.g., the U.S. Pharmacopeia (USP), British Pharmacopeia (BP), National Formulary (NF), European Pharmacopoeia (EP), Japanese Pharmacopeia (JP), etc.). Pharmaceutical grade further incorporates suitability for administration by means including topical, ocular, parenteral, nasal, pulmonary tract, mucosal, vaginal, rectal, intravenous and the like.
The present disclosure is based on the unexpected discovery that reducing physiological bloodstream pH in a subject is useful in treating, ameliorating, and preventing many conditions and diseases and symptoms thereof in a subject in need. The invention provides a stable therapeutic composition that can be administered to a subject in need thereof, in order to provide the requisite shift in blood pH.
A similar metabolic dysfunction occurs as a result of poor perfusion leading to a lactate burden, called metabolic acidosis in chronic state, which may be caused by, e.g., sepsis, multiple system atrophy (MSA), and ischemic conditions in peripheral limbs. For individuals incurring a chronic lactate burden, high blood levels of lactate steadily displace bicarbonate buffers to maintain acid-base homeostasis. A fraction of bicarbonate could then be removed by renal action to maintain homeostasis, and to reduce bloodstream bicarbonate levels. In addition, chronic disturbances in electrolytes can shift the setpoint for bicarbonate retention to additionally reduce stores. Such forces would in turn make less bicarbonate accessible for intracellular retention and intracellular buffering, ultimately reducing intracellular H+ stores. This reduction in H+ stores would require more Ca2+ to sustain a desired chemiosmotic gradient, leading to a dysfunctional ionic balance as described above.
Stable therapeutic compositions of the present disclosure reduce the physiological bloodstream pH in a subject, and maintain that reduction in physiological bloodstream pH for a duration of time, until renal and respiratory compensation processes negate the reduction, commonly followed by an alkaline “rebound”. The compositions of the present disclosure are formulated such that the formulated pH is below the physiologic norm (i.e., below 7.4). Bicarbonate concentration may, in some instances, be above physiologic norm (i.e., above 29 mM). The sudden influx of H+ ions, together with excess bicarbonate, and the manipulation of the electrochemical gradients that results, allows for a return to normal mitochondrial metabolic processes, while other electrolyte, vitamin, and antioxidant support present in compositions of the present disclosure reduce the damage from oxidative stress. Other benefits of administration of compositions of the present disclosure include improvement of at least one of cardiovascular conditions, vasodilation, wound healing, vascular plaque, bicarbonate servicing, electrolyte economy, metabolic dysfunction, oxygen deficiency, Citric Acid Cycle, renal system operation, antioxidant dysfunction, angiogenesis, nitric oxide (NO) dysfunction, hormone function, and anemia.
In one embodiment of the invention, the compositions of the present invention are suitable for improvement of cardiovascular conditions, by reducing or removing vascular plaques. Plaque forms in the arteries as a result of a number of factors, which are rooted in a wound-related signal dysfunction, including for example, lipid dysfunction, nitric oxide dysfunction and excessive ROS, which are caused, in part, by the presence of an acidic environment in the cells. For example, in an acidic environment, exogenous ROS levels become elevated. Smooth muscle contains several sources of ROS, which have been shown to function as important signaling molecules in the cardiovascular system. The elevated ROS signals to the smooth muscles to accrue in the arteries, as though recruited to fill wounds that do not actually exist. Additionally, in an acidic environment with ROS and an absence of nitric oxide, macrophages are signaled to respond to a non-existent threat, causing them to convert from the M1 to the M2 form, and begin sequestering lipids. The fat laden lipids become accumulations of foam cells. Also, in acidic environment, an endothelial nitric oxide synthase (eNOS) dysfunction occurs, causing an increased availability of arginase, which is necessary for the synthesis of collagen, and thus works with acid-pH stimulated action of fibroblasts to promote an accrual of collagen in the arteries. The elevations of retained intracellular Ca2+, and increases in unbound phosphate that occur from the metabolic dysfunction associated with an acidic environment (because less phosphate is complexed with ADP to form ATP), result in the promotion of calcific mineralized components of plaque. By restoring an alkaline environment in the cells, the compositions of the invention are able to reduce or reverse vascular plaque by correcting or improving at least one of, nitric oxide dysfunction (thereby restoring NO signaling), lipid dysfunction, eNOS dysfunction, reduction in smooth muscle recruiting, reduction of endogenous and exogenous reactive oxygen species (ROS), elevated Ca2+, or restoration of fatty acid metabolism. For example, upon the introduction of an alkaline environment, the smooth muscles, in the absence of the ROS signal, recognize the absence of a wound, and consequently, they down-regulate, and begin to directionally orient towards their vasodilation and vasoconstriction tasks. Also, for example, in an alkaline, low ROS environment in the presence of eNOS nitric oxide signaling, foam cells are signaled to release their lipids. Along with the calcific plaque reversal or reduction, the suppleness of the vascular vessel returns. In addition, the acid-shifting action of the drug liberates atomic components of the mineral deposits, while magnesium in the composition of the invention aids in the prevention of plaque re-deposition, to reduce the hardening of the arteries from the mineral deposit components.
In one embodiment of the invention, the compositions of the present invention are suitable for preventing or minimizing hypoxia in a subject. The lack of sufficient oxygen reaching cells or tissues in a subject can occur even when blood flow is normal. This can cause many serious, sometimes life-threatening complications. Use of the compositions of the invention enable the resolution or improvement of conditions commonly associated with hypoxia, such as, for example, heart attack, cardiovascular problems, lung conditions, concussive cascade, reperfusion injury, myocardial infarction, hypoxia associated with diabetes, tissue trauma, and the like. Many of these conditions are associated with vasoconstriction. The composition can counteract such vasoconstriction by promoting vasodilation via at least one of three pathways, namely endothelin, prostacyclin, or NO-soluble guanylyl cyclase (NO-sGC). For the endothelin pathway, the compositions elevate Mg2+ in the bloodstream to antagonize Ca2+. This blocks Ca2+ from potentiating vasoconstriction, allowing the arteries to relax and dilate. Meanwhile, the compositions also provide metabolic corrections to reduce metabolic sources of ROS, and reduce the presentation of endothelin stimulants at the cell surface, thereby reversing Ca2+ overstimulation. For the prostacyclin pathway, niacinamide in the composition elevates adenosine 3′,5′-cyclic monophosphate (cAMP) activity, which completes prostacyclin potentiation towards vasodilation. For the NO-sGC pathway, as noted above, the compositions of the invention provide a gradient of H+ flowing into the cells to promote Ca2+ efflux, which corrects elevated Ca2+ presentation. One effect of high levels of Ca2+ is the elevation of caveolin. As the caveolin elevate, they take residence in the caveoli on the cell surface, causing the displacement of eNOS, which migrates to the Golgi system. The combination of low ROS and low intracellular Ca2+ achievable using the composition of the invention, allows eNOS, to return from the Golgi to the cell membrane, thereby to restoring eNOS's ability to promote vasodilation. As the eNOS returns to the membrane, the bloodstream pH shifts, promoting NO release via the NO-sGC pathway, and promoting vasodilation. In addition, renal responses to rebalance pH produce a second “pH shift” towards alkaline, once again stimulating NO/NO-sGC vasodilation to extend the duration of the effect.
As shown in
The vasodilation that can be achieved by use of the composition of the invention makes the composition useful for wound care. It was unexpectedly discovered that use of the compositions of the invention may provide wound recovery even in subjects who have exhausted conventional treatment methods, including those with gangrenous presentation, or chronic, diabetic or traumatic wounds. Metabolic changes are among the effects observed following trauma injury and surgical trauma. These include inflammatory responses, which trigger a constriction of blood flow to the affected regions. While this advantageously minimizes blood loss at the site of an open wound or internal bleed, it may impair healing by promoting a hypoxic intracellular environment. In trauma situations where bleeding risk is absent or reduced (for example by compression), it may be desired to suppress the inflammatory response, to avoid secondary injuries from hypoxia. In cases of chronic inflammation, such as with chronic critical limb ischemia (CLI), the suppression of inflammation can expedite healing. The vasodilation promotion and improved perfusion caused by the composition of the invention contribute towards breaking the cycle of inflammation. In addition to promoting vasodilation in order to increase oxygen servicing, the compositions of the invention are also capable of correcting key metabolic aberrancies that are present in wounds. The compositions may, for example improve at least one of restoring acid-buffer status and correction of elevated Ca2+; reducing metabolic sourced ROS; correcting acidosis; correcting over-active iNOS and restoration of eNOS and nNOS function; promotion of beneficial angiogenesis after eNOS is corrected; and suppression of iNOS promoted aberrant angiogenesis, all of which are important for wound care.
Because H+ also administrates acetylcholine uptake, which is part of muscle support, and is a part of the cerebellum control process, and ATP is relevant for all of these systems, disorders of the central nervous system are another treatment target. Additionally, action to resolve intracellular acid, calcium accrual, reduced ROS, and increased Mg, are factors that can enhance function in the peroxisome, to better maintain catalase antioxidant supply, and additionally support the lipid modeling required for myelin maintenance of nerve sheaths.
In some instances, the reduction in physiologic bloodstream pH caused by the composition of the invention may be minimal, or not observed, due to the particular formulation of an administered composition, the rate at which a composition is administered, or both. However, the therapeutic benefits described herein may still be achieved due to the net elevation of bicarbonate concentration that occurs. Due to an excess of H+ upon administration, the body prioritizes retention of, and augmentation of, the buffer components (e.g., bicarbonate), as acid balancing processes proceed. Thus, a greater fraction of the buffering agent is retained within the cells and bloodstream as the system alkalinizes and returns the physiological pH towards baseline. Such an “alkaline rebound” may result in bloodstream pH overshooting slightly for a net alkaline stabilization relative to the starting pH. The “alkaline rebound’ achieves a higher residual concentration of intercellular and bloodstream buffer components, including bicarbonate. Alternatively, the system may regulate to a final pH equivalent to that present prior to treatment, but with bloodstream buffering, with regard to acidic species, being increased. Alternately, the bloodstream pH may settle to be more acidic than prior to the treatment, yet while a variety of aforementioned exchange phenomena are promoted. In contrast to infusion of a simple buffer, such as bicarbonate, in the absence of acidic components, co-administration of acid and buffer are key to limiting the H+ efflux rate, while the intracellular calcium correction is achieved.
In one embodiment of the invention, the compositions of the present invention are suitable for increasing nitric oxide synthase (NOS) in a subject. The pH biasing and increase in bicarbonate concentration as provided by compositions of the present disclosure (including decreases in pH upon administration and “alkaline rebounds” as homeostasis is restored) may also restore endothelial and neuronal NOS, leading to a selective increase in nitric oxide production. Nitric oxide is a gaseous signaling molecule with a role in, e.g., hemostasis, smooth muscle (particularly surrounding vasculature), neuronal signaling, and in the gastrointestinal tract. NO has been implicated in a variety of physiological systems, and the increased levels resulting from administration of the compositions described herein may serve a role in providing the therapeutic benefits described herein. For example, in glaucoma, NO may play a role in regulating intraocular pressure via the trabecular meshwork. In atherosclerotic plaques, NO stops the aberrant perpetuation of smooth muscle recruitment, foam cell accrual and lipid storage, and collagen deposition, and it may ultimately lead to reversal of plaque damage and a return of the vascular section to physiological norms.
In one embodiment of the invention, the compositions of the present invention are suitable for reducing lactate burden in a subject in need thereof. As used herein, the term “lactate burden” means any physiological condition characterized by elevated lactate levels. This may include, for example and without limitation, chronic lactate burdens such as acidosis, sepsis, and MSA, or acute lactate burdens such as may occur during and after physical exertion such as exercise. Lactate circulating oxygen debt burden that is retained in muscles, can be stimulated to be released by bicarbonate, and subsequently metabolized thus lowering the subject's lactate burden. The ability to eliminate lactate burden is important for a subject who has had, for example, an organ transplant. Where the transplant procedure involves the use of citrate anticoagulant, the citrate must be metabolized. This metabolization can induce a lactate burden in those individuals. Additionally, lactate burden is a component of sepsis and a chronic burden in diabetics. In the above instances, as well as in others involving a lactate burden, the use of the compositions of the invention may reduce that burden.
In one embodiment of the invention, the compositions of the present invention are suitable for reducing acidosis in a subject in need thereof, by administering to the subject the composition of the invention. One of the metabolic effects of trauma is the suppression of insulin, resulting in a reduction of the normal anabolic effect of insulin towards an increase in catabolic effects. This leads to a shift towards free fatty acids as the primary source of energy, with triglycerides providing 50 to 80% of the energetic need. Reducing the catabolic response encourages faster healing after surgery. These same mechanisms are in play in the diabetic patient, and become a larger challenge as subjects progress in their metabolic dysfunction. Underlying this catabolic process are aberrations in the metabolic chain that tend towards incomplete oxidation, leading to an increase in acidic products and an elevation of ROS from metabolic sources. As noted herein above, in trauma, this catabolic shift is driven by the hypoxic state, as inflammation and the vasoconstrictive response impair circulation. In diabetes, the shift is marked by glucose intolerance, and compounded by plaque-induced circulatory impairments and a sedentary lifestyle. In both cases, incomplete oxidation results in acidification in the cell and the promotion of transport biases which cause Ca2+ to concentrate in the cytosol. This concentration of Ca2+ cascades to the mitochondrial inner-membrane so that Ca2+ takes on a larger role in the chemiosmotic gradient, reducing the role of W itself. Such a shift in Ca2+ and H+ initiates a progressive shutdown in the electron chain transport (ECT), so that Ca2+ takes on a greater role in controlling the chemiosmotic potential. This also leads to an increase in metabolic ROS from ECT stages. Over time, impaired circulation reduces B-vitamin servicing, which impairs both the Krebs cycle and ECT, further increasing metabolic ROS. At the same time, impaired circulatory servicing reduces antioxidant maintenance to leave the elevation in ROS unchecked. While such aberrations have beneficial qualities, such as promoting the creation of NAPDH oxidases for bactericidal function during infection, they also present impairment to the healing process, as they promote catabolism. Furthermore, a balance of signals including acidosis, hypoxia, Ca2+, ROS and iNOS/NO, collectively suppress emergence of M2 macrophages, as desired, to promote healing. To address these aberrancies, the composition of the invention facilitates Ca2+ correction, and enhances B-vitamin servicing and ascorbic acid anti-oxidant servicing via elevated presentation. Additionally, acid burden is reduced, promoting an alkaline bias. Elevated HCO3− buffer levels also serve to preserve this alkaline bias.
The elements of metabolism referenced above also affect insulin management. For example, insulin release is stimulated from the pancreas when a signal of elevated Ca2+ is released to the bloodstream. For Ca2+ to be released to the pancreas, hydrogens must be created, through incomplete metabolism, to displace Ca2+ from the cytosol to the bloodstream. As noted herein-above, the Na+/K+ ATPase must be served with Mg2+ and ATP to facilitate the flooding Na+ to the bloodstream to ultimately stimulate the Na+/Ca2+ exchanger to release Ca2+ to the bloodstream. Additionally, for sensing of elevation to occur, the background level of Ca2+ in the bloodstream needs to be low enough for the pancreas to observe the change. In acidosis, this would be impaired as Ca2+ solubility is elevated in the blood and in the cytosol. As a further example, ROS, such as peroxide, can promote insulin function, when presented at low levels, and prevent presentation and action of insulin when presented at high levels. Thus, correction of acidosis and enhancement of Mg2+ are key to restore insulin management. So too are suppression of ROS (e.g., H2O2) through antioxidant support and facilitation of TCA and ECT function to achieve near-complete oxidation of Acetyl-CoA to CO2 and H2O.
Compositions
In one embodiment of the invention, the composition of the invention is a stable therapeutic composition that has been formulated to make it suitable for intravenous administration to a subject. The composition contains an intravenous buffer solution, containing at least one pharmaceutical grade acid, and at least one pharmaceutical grade pH buffering agent. To ensure their suitability for pharmaceutical use, the acid and buffer solution are present in a sterile aqueous solution. The concentration of the pharmaceutical grade acid and the pharmaceutical grade pH buffering agent in the buffer solution is sufficient to provide a total titratable acid content of from 60 mmol/L to 3000 mmol/L when administered to a subject. The acid and base are selected so that they are able together, to provide a buffer solution having a pH of between 4 and 7.7.
In one embodiment of the invention, the concentration of the pharmaceutical grade acid and the pharmaceutical grade pH buffering agent in the buffer solution is sufficient to provide a total titratable acid content of from 80 mmol/L to 3000 mmol/L when administered to a subject, where the buffer solution is effective to provide a buffer solution pH of less than 5.5. In another embodiment of the invention, the concentration of the pharmaceutical grade acid and the pharmaceutical grade pH buffering agent in the buffer solution is sufficient to provide a total titratable acid content of from 100 mmol/L to 2000 mmol/L when administered to a subject, where the buffer solution is effective to provide a buffer solution pH of less than 5.5. embodiment of the invention, the concentration of the pharmaceutical grade acid and the pharmaceutical grade pH buffering agent in the buffer solution is sufficient to provide a total titratable acid content of from 200 mmol/L to 1000 mmol/L when administered to a subject, where the buffer solution is effective to provide a buffer solution pH of less than 5.5.
In one embodiment of the invention, the concentration of the pharmaceutical grade acid and the pharmaceutical grade pH buffering agent in the buffer solution is sufficient to provide a total titratable acid content of from 40 mmol/L to 3000 mmol/L when administered to a subject, where the buffer solution is effective to provide a buffer solution pH of less than greater than or equal to 5.5. In another embodiment of the invention, the concentration of the pharmaceutical grade acid and the pharmaceutical grade pH buffering agent in the buffer solution is sufficient to provide a total titratable acid content of from 60 mmol/L to 2000 mmol/L when administered to a subject, where the buffer solution is effective to provide a buffer solution pH of less than greater than or equal to 5.5. embodiment of the invention, the concentration of the pharmaceutical grade acid and the pharmaceutical grade pH buffering agent in the buffer solution is sufficient to provide a total titratable acid content of from 80 mmol/L to 3000 mmol/L when administered to a subject, where the buffer solution is effective to provide a buffer solution pH of less than greater than or equal to 5.5.
An acid is a molecule or ion that is capable of donating a hydrogen ion H+. The amount of H+ ions in a solution is measured by its pH, where a pH of less than 7 constitutes an acidic pH. Humans typically have a bloodstream pH of 7.4. Compositions of the present disclosure comprise an acid that provides an amount of H+ ions to decrease the physiological bloodstream pH in a subject. Without being bound to any theory, it is believed compositions of the present disclosure increase the H+ gradient in various cellular environments, including, e.g., mitochondria. This increased mitochondrial H+ gradient drives higher production of ATP and, through other physiological homeostatic systems, causes changes in concentration gradients of the cellular membranes which in turn rebalances physiological ions such as sodium, magnesium, potassium, and calcium. For example, an increased H+ gradient in the bloodstream may stimulate calcium pumps in cellular membranes, thereby increasing intracellular H+ and reducing intracellular Ca2+. The concentration gradients of sodium, magnesium, and potassium are also affected. By manipulating ionic gradients using compositions of the present disclosure, many conditions and diseases and symptoms thereof may be treated, ameliorated, or prevented.
In some embodiments, compositions of the present disclosure are sufficient to reduce the bloodstream pH of a subject by a small, moderate, or large amount. In some embodiments, the amount of acid in a composition of the present disclosure is sufficient to reduce the bloodstream pH of a subject by 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.15, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, or 1.1, or more. The reduction in pH may also be expressed by the desired pH level of the bloodstream after administration of a composition of the present disclosure, e.g., 7.2. In some embodiments, a composition of the present disclosure comprises sufficient acid to reduce the bloodstream pH of a subject to 7.3, 7.2, 7.1, 7.0, 6.9, 6.8, 6.7, 6.6, 6.5, 6.4, or 6.3. A reduction of bloodstream pH to below 6.3 is not typically advised, as it may pose a cell health risk and threaten the integrity of cellular phospholipid bilayers. In cases of alkalosis where nominal pH may exceed 7.4, a “reduction” in pH provided by administration may still result in a bloodstream pH exceeding 7.4. For example, administration of a composition of the present disclosure may shift the physiological pH from 7.7 to 7.5.
Compositions of the present disclosure may contain one or more pharmaceutical grade acids. In some embodiments, compositions of the present disclosure comprise a mixture of one or more pharmaceutical grade acids. Acids may include any physiological acceptable acid, including, without limitation, hydrochloric acid, ascorbic acid, citric acid, lactic acid, phosphoric acid, or combinations thereof. The pH of a composition of the present disclosure may be between about 4 and 7.7. In some embodiments, the pH of a composition of the present disclosure is between about 6.1. In embodiments where the pH of the composition is very low, the rate of administration may have to be managed to avoid tissue damage adjacent to the injection site as dilution is effected in the bloodstream.
In another aspect, compositions of the present disclosure comprise a pH buffering agent. A pH buffering agent is a weak acid or base that is used to maintain the pH of a solution near a desired value. Compositions of the present disclosure comprise a pH buffering agent such that the reduction in bloodstream pH may be sustained for a desired duration. In some embodiments, the pH buffering agent may comprise a conjugate acid or a conjugate base. In some embodiments, the pH buffering agent may comprise any physiological acceptable buffering agent, including, without limitation, sodium bicarbonate, a phosphate buffer, citrate buffer, or a synthetic buffer creating specific alkaline conditions (e.g., tris-hydroxymethyl amino methane), or combinations thereof.
The buffer capacity of a solution is a measure of the solution's ability to resist pH change, i.e., to maintain a specific pH level. As discussed above, acid-base homeostasis relates to the proper balance of acids and bases in extracellular fluids, i.e., the pH of the extracellular fluid. In humans, the pH of plasma is approximately 7.4 and is tightly maintained around that value by three interconnected systems: 1) buffering agents, including bicarbonate, phosphate, and proteins), 2) the respiratory system, which impacts the partial pressure of carbon dioxide in blood plasma, and 3) the renal system, which excretes waste acids and bases. Accordingly, in some embodiments, compositions of the present disclosure comprise a pH buffering agent in order to maintain the desired bloodstream pH level below the typical pH value of about 7.4 in the face of pressures exerted by the physiological systems that regulate acid-base homeostasis. In some embodiments, compositions of the present disclosure comprise a pH buffering agent in an amount sufficient to maintain the reduction in bloodstream pH, or to maintain the desired pH level, for a duration of 1 minute to 1 week.
The desired duration of the reduced bloodstream pH level will depend on the particular indication being treated as well as the individual being treated. In some embodiments, a small, moderate, or large buffer capacity may be desired. In one means of administration, a small quantity of drug and/or a slow administration of a drug product could stimulate compensatory processes that can be respiratory or renal, so as to mitigate observable acid shifting potential, but having stimulated respiratory and renal activity. In such cases, a blood stream response may be neutral or may tend toward alkaline. Alternatively, administration of a high dose, and/or a dose with a fast administration rate, such as a bolus or fast IV drip could introduce the acid and overwhelm the compensatory processes to yield an observable downstream pH toward acidic. Such a stimulus would commonly be expected to be followed by a rebound of bloodstream pH towards alkaline throughout the treatment or post-treatment. The outcome resulting from a given dose level and/or administration rate may be different from patient to patient and from administration to administration as the patient's health, electrolytic status, pH status and compensatory process status evolve. Different buffer capacities may be sufficient to maintain the reduction in bloodstream pH for a duration of 1 minute to 1 week. In other embodiments, the buffer capacity may also be expressed in molar equivalent of common buffers, such as bicarbonate.
In some embodiments, the composition has a buffer capacity between 0.1 mM HCO3− equivalent and 1200 mM HCO3− equivalent. In other embodiments, the buffer capacity is between 0.1 mM HCO3− equivalent and 10 mM HCO3− equivalent. In some embodiments, the buffer capacity is between 10 mM HCO3− equivalent and 50 mM HCO3− equivalent. In some embodiments, the buffer capacity is between 10 mM HCO3− equivalent and 1000 mM HCO3− equivalent. In some embodiments, the buffer capacity is between 50 mM HCO3− equivalent and 800 mM HCO3− equivalent. In some embodiments, the buffer capacity is between 100 mM HCO3− equivalent and 600 mM HCO3− equivalent. In some embodiments, the buffer capacity is between 200 mM HCO3− equivalent and 550 mM HCO3− equivalent. In some embodiments, the buffer capacity is between 20 mM HCO3− equivalent and 100 mM HCO3− equivalent. In other embodiments, buffer capacity may be expressed by the molar concentration of HCO3−, or other common buffers. For example, in some embodiments, the molar concentration of HCO3− may be between 0.01 molar and 10 M. In other embodiments, the molar concentration of HCO3− may be between 0.5 and 2 M.
In another embodiment, the present disclosure provides a composition having a pH below physiological pH (i.e., below 7.4) and an HCO3− concentration above physiological levels (i.e., above 29 mM). In some embodiments, the pH of the composition may be between 4 and 7.7 and the HCO3− concentration may be between 30 mM and 2 M). In other embodiments, the pH of the composition may be between 5.5 and 7.4. In further embodiments, the pH of the composition may be around 6.
In another embodiment, the present disclosure provides a stable therapeutic composition comprising a buffer solution comprising a pharmaceutical grade base and at least one pharmaceutical grade conjugate acid, wherein the buffer solution is sufficient to raise the physiological bloodstream pH of a subject by 0.1 to 1.1, and wherein the buffer solution has a buffer capacity sufficient to sustain the elevation of the physiological bloodstream pH. In some embodiments the buffer capacity may be sustained for a period of time for example 1 minute or 1 week. The compositions may further comprise vitamins, salts, acids, amino acids or salts thereof, and stabilized oxidative species.
In another aspect, compositions of the present disclosure may further comprise salts to provide sources of physiological relevant ionic species, such as Na+, K+, Mg2+, Cl−, PO43−, or Ca2+. These may include, without limitation, sodium chloride, disodium phosphate, potassium chloride, monopotassium phosphate, magnesium chloride, and calcium chloride. The compositions may further comprise other trace elements and their salts, including, but not limited to, selenium, copper, chromium, iodine, fluoride, zinc, manganese, molybdenum, and iron.
Sodium ions are required in relatively large concentrations for normal physiological functioning. It is the major cation of the extracellular fluid. It plays an important role in many physiological processes, including the regulation of blood volume, blood pressure, osmotic equilibrium, and pH, as well as the generation of nerve impulses.
Potassium ions are the major cation of intracellular fluid, and, with the sodium ions of the extracellular fluid, is a primary generator of the electrical potential across cellular membranes. Accordingly, it plays a significant role in normal functioning, and is critical in such body functions as neurotransmission, muscle contraction, and heart function.
Calcium ions are likewise important to many physiological processes. In particular, Ca2+ ions are one of the most widespread second messengers used in signal transduction. In endothelial cells, Ca2+ ions may regulate several signaling pathways which cause smooth muscles surrounding blood vessels to relax. Dysfunction within Ca2+-activated pathways can lead to an increase in tone caused by unregulated smooth muscle contraction. This type of dysfunction can be seen in cardiovascular diseases, hypertension, and diabetes.
Magnesium ions are required in relatively large concentrations in normal metabolism. It is recognized that deficiency of magnesium is rare unless it is accompanied by severe losses in other electrolytes such as in vomiting and diarrhea. It is however frequently recognized as deficient in the modern diet with symptoms such as muscle tremors and weakness. This mineral is important in many enzymatic reactions and will stabilize excitable membranes. Administered intravenously, magnesium may produce an anesthetic action and this is indirect evidence of its action on the vascular wall endothelial component to stabilize and normalize the surface of the vascular wall.
In some embodiments, a composition of the present disclosure comprises Na+ at a concentration between 0.1 mM and 1 M. In other embodiments, a composition of the present disclosure comprises K+ at a concentration between 0.0 mM and 1 M. In some embodiments, a composition of the present disclosure comprises Mg2+ at a concentration between 0.1 mM and 1 M. In other embodiments, a composition of the present disclosure comprises Ca2+ at a concentration between 0.1 mM and 1 M.
As described above, the interplay between the various ionic species is disrupted in various physiological conditions, and compositions of the present disclosure may include these species to aid in the restoration of normal physiological conditions and concentrations. For example, high intracellular Ca2+ may be restored to a lower level as offset by Mg2+, K+, and H+, which may lead to NOS presentation in the cytosol and restoration of NO levels.
As stated above, the compositions described herein may include vitamins and vitamers, which is a substance(s) that has vitamin-like activity. Vitamins selected from the group consisting of the water soluble and lipid soluble group, and a combination of two or more thereof may also be added to the pharmaceutical composition. Preferably, the pharmaceutical composition includes ascorbic acid. Ascorbic acid is included as a strong antioxidant component and to maintain the structural integrity of connective tissue, including epithelial basement membranes and to promote wound healing. It may also play a distinct role as an agent with strong anti-inflammatory actions. The oxidized form of the vitamin, dehydroascorbic acid, has been shown to transfer intracellularly where some of it is reduced within the cell via action of glutathione. Deficiencies of other B group and A and E are also protected by ascorbic acid and corresponding interactions of dehydroascorbic acid and glutathione. In some embodiments, a composition of the present disclosure comprises dehydroascorbic acid, an oxidized form of ascorbic acid that is actively imported into the endoplasmic reticulum of cells via glucose transporters. Presentation of dehydroascorbic acid can also stimulate production of glutathione in the liver, which facilitates recycling of dehydroascorbic acid into ascorbic acid. Thus, dihydro-ascorbic acid indirectly enhances intracellular antioxidant resources. Dehydroascorbic acid may be present via direct inclusion of pharmaceutical grade dehydroascorbic acid, or by conversion of ascorbic acid via contact with a reactive oxygen species such as HOCl, H2O2, or OCl.
The B Group of Vitamins has been shown to be important in human food intake, and plays an important role acting as co-enzymes in cellular metabolism and energy production. The entire B group of vitamins may be included in the formulation to address any deficiencies in the patient population to be treated.
The B group vitamins are found to occur naturally together in foods and are generally included comprehensively for this reason. The B group includes: 1) Thiamine (B1), which plays an important role in energy production within the cell, specifically as co-enzyme in metabolism of carbohydrates. At least 24 enzymes are known to use thiamine as a co-enzyme; 2) Riboflavin (B2) in the form of flavin mononucleotide and flavin adenine dinucleotide are part of all dehydrogenase enzymes. Deficiency of this vitamin causes inflammation of the mouth, tongue, dermatitis, defective vision and blood dyscrasias; 3) Niacinamide (B3) is included, as part of the B group of vitamins as deficiency syndromes in clinical pellagra are well known clinical manifestations of deficiencies. The deficiency states of this vitamin are associated with intestinal diseases and alcohol misuse. It also occurs in diabetes mellitus and carcinoid syndrome. The active forms of this vitamin include the nicotinamide dinucleotides NAD and NADP, which are the co-enzymes and co-substrates for numerous dehydrogenases responsible for oxidation-reduction systems within the human cell, which are indispensable for energy production.
The formation of nicotinic acid from the administered nicotinamide in the formulation produce nicotinic acid possessing additional actions not shared by nicotinamide, such as inhibition of cholesterol synthesis; 4) Calcium D-Pantothenate (B5), pantothenic acid forms a major part of the molecule of co-enzyme A, which is important in the energy producing metabolic cycles in the mitochondria of all cells. The effect of this vitamin on various disease syndromes has been recognized. Such as its use in neurotoxicity produced by streptomycin and it's use in diabetic neuropathy, skin diseases and adynamic ileus; and 5) Pyridoxine (B6) is widely utilized as a co-enzyme in over 40 types of enzymatic reactions. The B Group of vitamins may also aid in providing an increase of antioxidants and stimulated glutathione to reduce reactive oxygen species, which ultimately aids in NO expression.
The most important of these are the transamination reactions and the influence of pyridoxine on tryptophan metabolism. Kynureminase, which is an enzyme used to identify pyridoxine deficiencies, loses its activity when pyridoxine is not present and may result in secondary nicotinic acid deficiency as a result of lack of the kynureminase conversion of nicotinic acid from tryptophan.
Cyanocobalamin (B12) is used because of the frequent reports of mal-absorption of cyanocobalamin, caused by poor dietary habits, senescence, and certain drugs (metformin) used as a hypoglycemic agent in diabetes mellitus. This vitamin is essential for normal erythropoiesis to occur, and recent findings have also implicated this vitamin with improvement of neuronal transmission in motor neuron disease. (Rosenfeld, Jeffrey and Ellis, Amy, 2008, Nutrition and Dietary Supplements in Motor Neuron Disease, Phys Med Rehabil Clin N Am., 19(3):573-589).
Vitamin K is a fat-soluble vitamin. There are two naturally occurring forms of the vitamin. Vitamin K1 is the dietary Vitamin K and is abundant in green leafy vegetables, whereas vitamin K2 is present in tissues. Vitamin K2 is synthesized by bacteria. It is found mainly in fermented products like fermented soybeans, cheese, curds and to some extent also in meat and meat products (Thijssen, H. H., M. J. Drittij-Reijnders, and M. A. Fischer, 1996, Phylloquinone and menaquinone-4 distribution in rats: synthesis rather than uptake determines menaquinone-4 organ concentrations, J Nutr 126:537-43). Vitamin K2 is found in animals as menaquinone. It is the human activated form of vitamin K and is said to promote the healing of bone fractures. It is essential for the carboxylation of glutamate residues in many calcium binding proteins such as calbindin and osteocalcin. These proteins are involved in calcium uptake and bone mineralization.
There is an established daily dosage for vitamin K1 for, but not for vitamin K2. A typical therapeutic oral dose for vitamin K2 for osteoporosis is 45 mg/day. Unlike for coagulation, a much higher level of vitamin K is needed for complete gamma-carboxylation of osteocalcin (Booth, S. L., and J. W. Suttie, 1998, Dietary intake and adequacy of vitamin K, J. Nutr 128:785-8). Vitamin K deficiency is associated with reduced hip bone mineral density and increased fracture risk in healthy elderly women. Animal studies have shown that the most potent form of vitamin K is vitamin K2, which was administered to rats at 0.1 mg/kg orally (Akiyama, Y., K. Hara, A. Matsumoto, S. Takahashi, and T. Tajima, 1995, Comparison of intestinal absorption of vitamin K2 (menaquinone) homologues and their effects on blood coagulation in rats with hypoprothrombinaemia, Biochem Pharmacol 49:1801-7). Vitamin K2, in the form of menaquinone-4, is the most biologically active form. It has been extensively studied in the treatment of osteoporosis. In one of these studies, 241 osteoporotic women were given 45 mg/day vitamin K2 and 150 mg elemental calcium. After two years, vitamin K2 was shown to maintain lumbar bone mineral density, significant lower fracture incidence (10% versus 30% in the control group (Shiraki, M., Y. Shiraki, C. Aoki, and M. Miura, 2000, Vitamin K2 (menatetrenone) effectively prevents fractures and sustains lumbar bone mineral density in osteoporosis, J Bone Miner Res 15:515-21).
Vitamin K2, but not vitamin K1, may inhibit the calcification of arterial plaque. In 1996, animal studies involving rats found high dose of vitamin K2 (100 mg/kg body weight daily) inhibited the increase in calcium in both kidneys and aorta induced by megadose of synthetic vitamin D (Seyama, Y., M. Horiuch, M. Hayashi, and Y. Kanke, 1996, Effect of vitamin K2 on experimental calcinosis induced by vitamin D2 in rat soft tissue, Int J Vitam Nutr Res 66:36-8). A similar study was conducted with rabbits. High dose of Vitamin K2 (1-10 mg/kg daily for 10 weeks) inhibited the atherosclerotic plaque progression in the aorta and pulmonary arteries (Kawashima, H., Y. Nakajima, Y. Matubara, J. Nakanowatari, T. Fukuta, S. Mizuno, S. Takahashi, T. Tajima, and T. Nakamura, 1997, Effects of vitamin K2 (menatetrenone) on athero-sclerosis and blood coagulation in hypercholesterolemic rabbits, Jpn J Pharmacol 75:135-43).
Vitamin K2 was also seen to reduce total cholesterol levels, lipid peroxidation, ester cholesterol deposition in the aorta and factor X activity in plasma compared to the control group. A study involving more than 500 postmenopausal women investigated the relation between vitamin K1 and vitamin K2 intake and coronary calcification. Sixty-two percent of the women sampled for the study had coronary calcification. Only vitamin K2 intake was associated with the trend toward decreasing coronary calcification (Beulens, J. W., M. L. Bots, F. Atsma, M. L. Bartelink, M. Prokop, J. M. Geleijnse, J. C. Witteman, D. E. Grobbee, and Y. T. van der Schouw, 2009, High dietary menaquinone intake is associated with reduced coronary calcification, Atherosclerosis 203:489-93).

In some embodiments, the composition may be provided in 20 mL vials. A composition of the present invention may be further diluted prior to administration. For example, a 20 mL vial may be diluted with saline to a 100 mL dispensed volume for administration. In other embodiments, the liquid formulation may be reduced to dry solid via lyophilization. The lyophilized formulation may then be reconstituted to a particular volume prior to administration.
Table 1 shows various formulations of the composition according to exemplary embodiments of the present disclosure per 20 mL vial:

As one non-limiting example, the acid and buffer components of a composition may be separated into two vials. Other components of compositions of the present disclosure (e.g., cyanocobalamin, calcium d-pantothenate, and/or others) may be included in these vials or further separated into additional vials.
Methods of Treatment
In another aspect, the present disclosure provides methods of treatment. The methods of the invention involve administering the composition of the invention to subjects in need thereof.
One embodiment of the invention is a method of treating or ameliorating a mitochondrial disorder, metabolic disorder, a condition associated with diabetes, a cardiovascular dysfunction, or an ocular condition in a subject in need thereof, by administering to the subject a stable therapeutic composition of the present disclosure.
Mitochondrial dysfunction, characterized by a loss of efficiency in the electron transport chain and reductions in the synthesis of high-energy molecules, such as ATP, is a characteristic of aging, and essentially, of all chronic diseases.

Compositions of the present disclosure may also be formulated for intravenous, bolus, dermal, oral, otic, suppository, buccal, ocular, or inhalation delivery. For intravenous or parenteral administration, i.e., injection or infusion, the composition may also contain suitable pharmaceutical diluents and carriers, such as water, saline, dextrose solutions, fructose solutions, ethanol, or oils of animal, vegetative, or synthetic origin. It may also contain preservatives, and buffers as are known in the art. When a therapeutically effective amount is administered by intravenous, cutaneous or subcutaneous injection, the solution can also contain components to adjust pH, tonicity, stability, and the like, all of which is within the skill in the art. For topical administration, the composition may be formulated in, e.g., liquid, gel, paste, or cream. In some embodiments, the composition may be administered via a topical patch. For ocular administration, the composition may be formulated in, e.g., liquid eye drops, or as a gel, paste, or cream to be applied to the surface of the eye and/or surrounding tissue. For otic administration, the composition may be formulated in, e.g., ear drops.
A composition for intravenous, cutaneous, or subcutaneous injection should contain, in addition to peptide an isotonic vehicle such as Sodium Chloride Injection, Ringer's Injection, Dextrose Injection, Dextrose and Sodium Chloride Injection, Lactated Ringer's Injection Citrate Buffer pH 5.5, or other carriers, diluents and additives as known in the art. As described fully elsewhere herein, the pharmaceutical composition of the present invention may also contain stabilizers, preservatives, buffers, antioxidants, or other additive known to those of skill in the art. The pharmaceutical compositions are formulated for intravenous or parenteral administration. Typically, compositions for intravenous or parenteral administration comprise a suitable sterile solvent, which may be an isotonic aqueous buffer or pharmaceutically acceptable organic solvent.
As described fully elsewhere herein, where necessary, the compositions can also include a solubilizing agent. Compositions for intravenous or parenteral administration can optionally include a local anesthetic to lessen pain at the site of the injection. Generally, the ingredients are supplied either separately or mixed together in unit dosage form in a hermetically sealed container such as an ampoule or sachet. The pharmaceutical compositions for administration by injection or infusion can be dispensed, for example, with an infusion bottle containing, for example, sterile pharmaceutical grade water or saline. Where the pharmaceutical compositions are administered by injection, an ampoule of sterile water for injection, saline, or other solvent such as a pharmaceutically acceptable organic solvent can be provided so that the ingredients can be mixed prior to administration.
The duration of intravenous therapy using the pharmaceutical composition of the present invention will vary, depending on the condition being treated or ameliorated and the condition and potential idiosyncratic response of each individual mammal. The duration of each infusion is from <1 minute (e.g., bolus injection) to about 1 hour (intravenous delivery). The infusion can be repeated within 24 hours. Thus, a mammal can receive about 1 to about 25 infusions per day. Preferably, the number of infusions per day is 1 or 2. The period between each infusion can be 1, 2, 5, 10, 20, 30, 40, 50 minutes, or 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 hours or more. The administration may also be administered at any of a variety of cadences, including hourly, daily, weekly, monthly, quarterly, bi-annually, annually, etc., or any other particular timeframe depending on the condition to be treated and/or the response of each individual mammal. In other embodiments, a pharmaceutical composition of the present invention may be administered as a single event, or may be administered over week-long, multi-week, month-long, year-long, or multi-year durations, or for any other desired duration as may be warranted.
Alternatively, the infusions can be given one after another without a substantial period in between. In one embodiment, the infusion lasts about 45 minutes. The dose may be repeated 2-3 times a week depending on the severity of the relative or absolute deficits of nutrients in the patient. A clinical assessment may be necessary in order to establish the status, but can be limited to a review of medical history, subjective review of symptoms, the subjective opinion of the mammal when human or upon review of any specific deficits.
In another embodiment of administration, administration is alternated between two solutions: one acid shifting (AS) and one base shifting (BS) as described above. Alternating administration of AS/BS/AS/BS in various cadences would be expected to induce more pH swings from acidic towards basic or from basic towards acidic. Such events, as induced through exercise, are recognized for their value in promoting nitric oxide (NO) release for vasodilation (Capellini, Verena K., et al., 2013, The Effect of Extracellular pH Changes on Intracellular pH and Nitric Oxide Concentration in Endothelial and Smooth Muscle Cells from Rat Aorta, PLOS One, 8(5):e62887), and to promote cardiolipin repair and remodeling (Khalafat, Nada, et al., 2011, Lipid Packing Variations Induced by pH in Cardiolipin-Containing bilayers: The Driving Force for the Cristae-Like Shape Instability, Biochimica et Biophysica Acta—Biomembranes, 1808(11):2724-2733). These alternating administrations may each last between 0.5 and 60 minutes, and may be alternated one, two, or more times as necessary to achieve the desired therapeutic effect. The AS and BS administrations need not necessarily be identical in either their shifting effect or duration of administration. That is, for example, an AS composition may affect a larger shift over a shorter administration, while the BS composition may affect a smaller shift over a longer administration. In some embodiments, an exemplary administration profile may be a 5 minute AS administration followed by a 10 minute BS administration, repeated two times (i.e., 5/10/5/10). Other exemplary administration profiles may be, e.g., 10/10/10/10 or 0.5/0.5/0.5/0.5.
Systemic formulations include those designed for administration by injection, e.g., subcutaneous, intravenous, intramuscular, intrathecal or intraperitoneal injection. Useful injectable preparations include sterile suspensions, solutions or emulsions of the active compound(s) in aqueous or oily vehicles. The compositions also can contain solubilizing agents, formulating agents, such as suspending, stabilizing and/or dispersing agent. The formulations for injection can be presented in unit dosage form, e.g., in ampules or in multidose containers, and can contain added preservatives. For prophylactic administration, the compound can be administered to a patient at risk of developing one of the previously described conditions or diseases. Alternatively, prophylactic administration can be applied to avoid the onset of symptoms in a patient suffering from or formally diagnosed with the underlying condition.
The amount of compound administered will depend upon a variety of factors, including, for example, the particular indication being treated, the mode of administration, whether the desired benefit is prophylactic or therapeutic, the severity of the indication being treated and the age and weight of the patient, the bioavailability of the particular active compound, and the like. Determination of an effective dosage is well within the capabilities of those skilled in the art coupled with the general and specific examples disclosed herein.
Formulations can comprise other ingredients for the treatment of the organism as a whole. For example, an anti-oxidant additive and/or pro-oxidant additive can be present. The latter may be an agent that acts as a preventive, while the former may be an agent that acts to treat a specific medical condition.

Kits
One embodiment of the invention includes a kit for administering the stable therapeutic composition of the present disclosure to a subject. In this embodiment, the kit may contain the composition in a single vial or in more than one vial. The vial can preferably be an injection vial with a membrane that is suitable for inserting a syringe to pull the solution from the vial or a soft I.V. infusion bag. The composition of the invention is contained in the vial in a sterile aqueous solution. The solution can be provided as a concentrated solution to which a diluent is added prior to administration. The diluent can be sterile water. The kit may further comprise a pre-filled container which contains the diluent. In a preferred embodiment, a soft infusion bag is pre-filled with diluent. Alternatively, the composition vial can contain a solution that is at a concentration which is suitable for injection without any dilution. Preferably, the solution for injection is isotonic. That is, the solution can contain salt, carbohydrates, such as glucose, NaHCO3 or amino acids, such as glycine, and is isotonic with blood plasma. In other instances, the solution may be hypotonic so as to promote more rapid intracellular uptake or hypertonic so as to promote slower intracellular uptake.
In one embodiment of the invention, the kit contains two vials. The first vial at least one pharmaceutical grade acid in a sterile aqueous solution. For example, the first vial may contain pharmaceutical grade ascorbic acid, thiamine HCl, magnesium sulfate, cyanocobalamin, niacinamide, pyroxidine HCl, riboflavin 5′ phosphate, calcium D-pantothenate, and an aqueous solvent containing sodium chloride and water (for injection). The second vial contains at least one pharmaceutical grade pH buffering agent in a sterile aqueous solution. For example, the second vial may contain pharmaceutical grade sodium bicarbonate and an aqueous solvent containing sodium chloride and water (for injection). The contents of the vials may be stored under refrigeration or under freezing conditions.
In another embodiment, the kit may contain a container of a lyophilized powder that may be reconstituted prior to administration. The lyophilized powder may be an isotonic solution.
Each kit described herein may further comprise instructions for use. The instructions will, of course, depend upon the kit itself and whether a diluent is to be used or other components to be admixed with the pharmaceutical grade buffer solution prior to administration.
EXAMPLES Example 1Experiments described herein were designed to validate key aspects of using buffered acidic solutions to acidically shift bloodstream pH for therapeutic purposes. Specifically, several aspects are illustrated: (1) Blood has acid-base properties that can be notionalized as a solution having a physiological pH and buffer capacity. Furthermore, therapeutic compositions designed to shift blood pH upon administration can be notionalized as solutions having a target pH and buffer capacity. (2) pH shifting of the bloodstream towards acidic conditions can be achieved via intravenous or intraarterial administration of an acid solution. (3) Alternative formulations having higher concentrations of buffer components have increased capacity to impede the restoration of bloodstream pH back towards physiologic. (4) Faster dissolution of calcified mineral forms can be achieved when the conditions are shifted from equilibrium at a given pH to lower pH levels.
The rationale, protocol, and results of these experiments are described in the following sections.
Acid-Base Properties of Blood
At physiologic norm conditions, blood is recognized to commonly have a pH value near 7.41. The is due to the presence of various acids within it (primarily HCl) and various buffers (primarily bicarbonate). In the interest of developing a surrogate to emulate the acid-base properties of blood, a water-based solution was prepared that contained HCl and HCO3. HCl and HCO3 were chosen for this surrogate as they are the primary acid and buffer species in blood. For this blood surrogate, 0.0024 M HCl in 5,000 ml of aqueous solution was buffered with 0.025 M of NaHCO3, to produce a resultant pH of 7.41 (Table 3). This surrogate was freshly prepared for each of the tests that were performed as CO2 loss will influence the pH over time if left to atmospheric exposure.
Similarly, drug products designed to shift blood pH could be formulated using a variety of physiologically compatible acids and buffers. To illustrate this, 4 example drug products (C1-C4: Table 3) were formulated using HCl and NaHCO3 as example acid and buffer components (Blood and Drug Compositions per Table 3 Below). By design, these would have pH below physiologic and be comprised of buffer products as well. C1 was designed to provide a small pH shift for a short time, C2 was designed to provide a small pH shift for a long time, C3 was designed to provide a large pH shift for a short time, and C4 was designed to provide a large pH shift for a long time.
First, C1, C2, C3, and C4 were formulated, as was the blood surrogate, and the pH was measured. The pH was also calculated per the Henderson-Hasselbalch equation. Second, the compositions C1, C2, C3, and C4 were added to the surrogate blood. Again, a pH value was calculated, and a pH value was measured. Upon administration into the bloodstream, each of the example therapeutic solutions shift the bloodstream pH from physiologic norm conditions (e.g., 7.41 pH) to reduced pH (e.g., 7.31-6.70 pH). This is demonstrated through addition of the C1 (or 2, 3, 4) to the blood surrogate solution, as summarized in Table 3. In this case, the therapeutic formulations with the lowest pH and/or larger buffer fraction are capable of imparting a larger shift in bloodstream pH.
To demonstrate the resilience of therapeutically shifted blood to resist return to physiologic, a fixed quantity of bicarbonate was added into each of the therapeutically shifted blood solutions. This was done to simulate pH restoring effects such as stimulation of additional buffer sources, CO2 respiration, and renal action to remove H+ and re-cycling of HCO3−. Such restorative forces were simulated by administering a fixed allocation of HCO3− to the therapeutically shifted blood surrogate solution. For a given quantity of added bicarbonate, the differing resilience of the C1-C4 compositions to resist blood pH restoration could be demonstrated. As shown in Table 3, the resilience to restoration can be expressed in terms of delta pH/gram HCO3, where a lower value implies a greater capacity to resist pH restoration forces. In this example, the formulations with more buffer capacity (C2 or C4) are more resistant to restore towards physiologic per gram of pH restoring bicarbonate added.
To demonstrate the ability of calcium salts to dissolve more readily in lower pH solutions, such as would be the case for calcified plaques in a pH-shifted bloodstream, calcium salts were submerged in therapeutically pH-shifted blood surrogate solution and dry weighed after select time intervals of submersion.
To this end the blood surrogate was first exposed to a large quantity of calcium salt for an extended period while at pH 7.41 to establish equilibrium of the salt at the start pH. Then residual solid calcium salts were removed, leaving a blood surrogate solution that was near-saturated with the calcium salt at the 7.41 pH. Then C1 (or 2, 3, 4) formulations were added to the calcium saturated blood surrogate to reduce the pH. Then the 2 g pellets of the calcium salts were submerged in therapeutically pH-shifted solution and dry weighed at select time intervals to establish a rate of weight loss (Table 4). Because the surface area and shape of the calcium mineral was common to all tests, the test demonstrates that lower pH solutions promote higher dissolution rates than higher pH solutions (˜0.043-0.044 g/min for pH 7.31 vs 0.054-0.059 g/min for pH=6.7)).
It will be apparent to one of ordinary skill in the art that various combinations and/or modifications and variations can be made in the compositions of the present disclosure depending upon and as dictated by the therapeutic needs of the patient. Moreover, features illustrated or described as being part of one embodiment may be used on another embodiment to yield a still further embodiment.
Example 2Studies were conducted by administering the therapeutic composition to three horses. The following materials were prepared for the study:
-
- 1. Subject 1—mare, 34 years old, Welsh Cross, 739 pounds, with a history of pre-diabetes, Laminitis with Cushing's disease, and Lymes presentation.
- 2. Subject 2—male neutered (gelding), 13 years old, Welsh Cross, 724 pounds, history of Laminitis with Cushing's disease, and Lymes presentation.
- 3. Subject 3—mare, 12 years old, Welsh Cross, 652 pounds, history of Lymes presentation.
- 4. Each Treatment involved the administration of an intravenous buffer solution:
- a. 100 ml of A-Vial AS* Solution (containing ascorbic acid, hydrochloric acid, and aqueous solvent containing sodium chloride and water), or 100 ml of A-Vial ASVM** Solution (containing ascorbic acid, dehydroascorbic acid, hydrochloric acid, thiamine HCl, magnesium sulfate, cyanocobalamin crystalline, niacinamide, pyroxidine HCl, riboflavin 5′ phosphate, and calcium D-pantothenate, and aqueous solvent containing sodium chloride and water).
- b. 100 ml of B-Vial Bicarbonate Solution (containing sodium bicarbonate and an aqueous solvent containing sodium chloride and water).
- c. 1000 ml Saline in an IV-ready bag, or 2000 ml Saline in an IV ready bag. * AS—grade sourced Acid Shifting Composition** ASVM—grade sourced Acid Shifting Composition additionally containing select Vitamins and Minerals
Methods:
Doses of the therapeutic composition were managed as follows:
Dosing was Administered as Follows:
A Vial products were refrigerated at 40° F. prior to use, while B Vial products were stored at 70° F. 100 ml of A Vial product was combined into a saline IV bag, and then 100 ml of B Vial product was combined into the IV bag. The IV bag was hung from an elevation point, 18″ above infusion point. A catheter was inserted into the jugular vein of the subject. Pre-treatment venous blood samples were extracted from the patient for IDEXX analysis (hematology, chemistry, endocrinology and serology) and blood gas analysis (acid/base status, Oximetry, Electrolytes, metabolites) (T=−5 min). Five minutes (T=0 min) later, the IV bag was connected to a catheter, and the drip was opened to begin infusion. Forty five minutes (T=4 5 min) later, the drip rate was adjusted to complete infusion. Venous blood samples were extracted from the subject during treatment, 15 minutes (T=15 min) and 30 minutes (T=30 min) after the treatment began. Post-treatment venous blood samples were extracted 60 minutes (T=60 min) and 120 minutes (T=120 min) after the treatment began. Post-treatment sample were subjected to blood gas analysis (acid/base status, Oximetry, Electrolytes and Metabolites)
* Note: Subject 1's “pre-treatment” venous blood samples for IDEXX analysis (hematology, chemistry, endocrinology and serology) were mistakenly sampled 60 minutes after treatment began. The results likely reflect post-dose changes in plasma volume, as large changes were observed for concentration-based markers (e.g., RBC, hematocrit).

Results Section 2: Electrolyte, Hb, Glu, and Lac Response:
Subject 2 AS Dose 1 and ASVM Doses 4 and 5—
Observed Response: Blood electrolytes, hemoglobin (Hb), Glucose (Glu) and Lactate (Lac) were observed at time intervals of 5 min pre-dose commencement (T=−5), 20 min post dose commencement (T=20), and 5 minutes post-dose complete (dose complete at T=45, measurement at T=50) as shown in Table 7.
Subject 2 ASVM Doses 4 and 5—Observed Hb Response and Inference of Plasma Volume Changes:
Over the observation timeframe, Hb reduced from its start value, sometimes showing evidence of rebound during the observation period. This cannot be interpreted as hemolysis, as a rebound on this timescale would be impossible. The change in Hb concentration is consistent with a change in blood volume, likely due to a change in plasma volume. Such exchange is required during exercise-like stimulus to maintain vascular pressure, under conditions of vasodilation, where vascular volume increases.
Subject 2 ASVM Doses 4 and 5—
Observed Glucose Response: Over the observation timeframe, Glucose was perturbed (up and down) from its start value, while showing evidence of rebound during the observation period. While the reduction could be attributable to increased blood volume, elevations in Glucose concentration cannot. Observed Glucose elevation is consistent with perturbation of glucose exchange, such as happens during exercise.
Subject 2 ASVM Doses 4 and 5—
Observed Lactate Response: Over the observation timeframe, Lactate was observed to have a low presentation value, which further reduced in Dose 4, and elevated slightly in Dose 5. This is consistent with the lactate burden steadily dropping with successive doses, as improved perfusion increased aerobic metabolism, so as to resolve lactate debt. Elevated lactate was seen in Dose 5, despite s suspected plasma volume dilution. This is consistent with presentation of HCO3- into muscles to release stored lactate.
Subject 2 ASVM Doses 4 and 5—
Observed Electrolyte Response: Over the observation timeframe, electrolyte exchange was observed. Potassium and Sodium were observed to drop during treatment, which could be attributed to increased plasma volume. It is consistent with a flow of H+ into the cell, elevating the Chemiosmotic gradient to improve ATP yield and enhancing action of the Na/K ATPase to transport K+ into the cell. At the same time, a reduction in bloodstream Calcium was observed. H+/Na+ exchange and K+/Na+ exchange would promote an elevation of bloodstream Na+, to promote Ca2+ exchange to the blood via the Ca2+/Na+ exchanger. Elevations in bloodstream were also observed during the observation period.
Results Section 4: Hematology, Chemistry, Endocrinology, and Serology:
Observed Response Between Day 1 and Day 8 Encompassing 4 Doses in 3 Horses:
Hematology, Chemistry, Endocrinology, and Serology were observed on Day 1, before Dose 1, and on Day 8, before dose 5, thus encompassing 4 doses of ASVM, or in some dose instances, AS. The following effects can be observed in the data, as shown in Table 8.
-
- White blood cell (WBC) and neutrophil counts were observed to drop for all subjects, consistent with an alleviation of the inflammation response.
- Platelet counts and fibrinogen were observed to rise for all subjects, consistent with control over clotting cascade and reduced consumption of clotting products. It is also consistent with increased production of platelets in bone marrow upon resolution of Thrombocytopenia, and increased presentation of fibrinogen through enhanced liver function.
- Creatinine was observed to rise in all subjects, consistent with an increase in muscle mass and improved capacity to store ATP in muscle as Phosphocreatine.
- BUN:Creatinine ratio was observed to fall for all subjects, consistent with increased flow through the kidneys.
- Ca2+ and K+ were observed to drop for all subjects, consistent with intracellular uptake of K+ via Na+/K+ ATPase, and renal extraction of Ca2+, so as to reduce bloodstream presentation. Reductions in Ca2+ and increases in K+ could have the potential to reduce chemiosmotic gradient dependence on Ca2+ so as to restore electron chain transport function, reduce corresponding ROS corresponding to the electron chain transport, and increase basal metabolic rate. A reduction in intracellular calcium, along with ROS reduction and alkaline conditions and elevated Mg2+, would also have the potential to improve peroxisome function to restore long-chain fatty acid reduction for metabolic use, increased capacity to repair myelin for enhanced nerve function, and improving catalase servicing from the peroxisome. Additionally lower Ca2+ could restore eNOS function by reducing caveolae bound Caveolin to allow eNOS to translocate from the Golgi back to the membrane caveolae. Lower intracellular calcium could also signal more M2 prenotype presentation for macrophages, microglia, and osteoblasts among others. Increased K+ could act to enhance muscle function and nerve transmission, reduce cramping of muscles, and provide other benefits.
- Creatine kinase was observed to drop for all subjects, consistent with a potential increase of consumption of creatine kinase in enzymatic action to promote storage of ATP with creatine as Phosphocreatine to enhanced stored energy in muscles. Alternately, the reduction in blood plasma can indicate a reduction in the ongoing rate of tissue damage, such as in myocardial infaction (heart attack), rhabdomyolysis (severe muscle breakdown), muscular dystrophy, autoimmune myositides, and acute kidney injury, so as to minimize presentation of damaged tissue contents to the bloodstream.
- Total T4 was observed to rise for all subjects, potentially indicating improved thyroid function to produce more thyroxine. This, among other things, is associated with increases in synthesis of Na+/K+ ATPases, glucose absorption, gycogenolysis, gluconeogenesis, lipolysis, protein synthesis, net catabolic degradation, cardiac beta-1 receptors for enhanced sympathetic nervous control, and basal metabolic rate.
- Equine endogenous ACTH was observed to fall for all subjects, consistent with a reduction in cortisol levels, so as to promote calming and anti-anxiety effects. Additionally consistent with promoting resolution of Cushing's disease.
- Lyme's antibodies were shown to reduce in ratio presentation, as indicated by a smaller divisor. This is consistent with resolution of Lyme's disease and progression towards immune quiescing, with reduction of inflammation response.
- Lyme's proteins were observed to increase in presentation, consistent with enhanced action of plasmin during alkaline rebound phases, which could reduce the fibrin layer associated with borrelia, so as to expose its surface proteins.
