BACKGROUNDMany mammals may experience functional deterioration as they enter mid to late adulthood. Functional deterioration relates to a decline in the ability to carry out basic functional activities such as eating and walking. Compromised motor function can, in turn, lead to loss of independence and a decreased quality of life.
A major contributor to functional deterioration in both sedentary and physically active mammals is sarcopenia, an age-related condition characterized by a gradual decline in muscle mass, strength, and function. In sarcopenia, the body experiences a global shift from muscle protein synthesis to muscle degradation.
Proteinogenic amino acid molecules can be categorized as essential and non-essential amino acids. Non-essential amino acids, which can be synthesized in the body, include alanine, asparagine, aspartic acid, glutamic acid, arginine, cysteine, glutamine, tyrosine, glycine, proline, and serine. Essential amino acids, such as histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine, cannot be biosynthesized and instead must be consumed via food or supplementation. In muscle protein synthesis, the availability of essential amino acids is rate-limiting. Therefore, supplementation of essential amino acids can potentiate protein synthesis. Muscle protein synthesis is activated by the mammalian target of rapamycin (mTOR) pathway. The mTOR pathway senses and responds to changes in amino acids and growth factors such as insulin-like growth factor (IGF-1). In particular, the mTOR complex phosphorylates ribosomal protein S6K, which in turn phosphorylates ribosomal protein S6 and substrates eIF4B and 4EBP1, consequently promoting mRNA translation and protein synthesis. The proteins involved in the mTOR pathway can serve as biomarkers for protein synthesis.
The NFκβ (p65/p50) pro-inflammatory signaling pathway has also been implicated in regulating muscle functionality. NFκβ protein levels are strongly upregulated in muscle atrophy, while inhibition of the NFκβ (p65/p50) pathway can prevent muscle degradation.
The ubiquitin-proteasome system (UPS) can facilitate muscle degradation, breaking down muscle proteins into peptides and then free amino acids. In the UPS-pathway, target muscle proteins are tagged with a degradation signal and then degraded into peptides by the 26s proteasome. The UPS-pathway can be mediated by atrogin-1 and MuRF-1, two E3 ubiquitin-protein ligases, and by cytokines such as interleukin (IL)-6, IL-8, and tumor necrosis factor (TNF)-α, which produce pro-inflammatory signals. These factors can serve as biomarkers for muscle protein degradation. Protein degradation and functional deterioration may be amplified in mammals with sarcopenia and in older mammals with sedentary lifestyles. Muscle protein building requires both new protein synthesis and prevention of protein degradation. While physical activity, even in light or moderate amounts, can lead to muscle hypertrophy and increased functionality, muscle disuse results in a decrease in protein synthesis and an increase in muscle breakdown. In addition, mTOR activation can be delayed in older adults, leading to decreased protein synthesis. Furthermore, extended periods of inactivity can lead to a decreased protein synthetic response to amino acid supplementation. Sarcopenia-related functional deterioration can be a reinforcing loop, as muscle loss and decreased functionality can interfere with physical activity. In turn, decreased physical activity leads to further muscle loss and decreased functionality.
In the past, leucine and creatine have been administered to mammals in order to increase muscle mass and strength. In particular, many of the supplements administered to elderly mammals for increasing muscle protein synthesis comprise complicated and expensive mixtures of amino acids. For example, U.S. Pat. No. 7,790,688, which is incorporated by reference herein, discloses compositions containing a complex blend of essential amino acids, creatine, and low-glycemic carbohydrates. Further, it is well-known in the art that ingestion of 20 grams or more of essential amino acids is necessary for stimulation of muscle protein synthesis in the elderly. As protein intake increases, however, urea production can increase in some individuals.
Consequently, a need exists for a supplement that can increase muscle protein synthesis, lean mass, functional strength, and/or overall quality of life in mammals without having any substantial adverse effects on other body functions. A need also exists for a simpler and less expensive supplement that can improve muscle mass and/or functional strength leading to increase in physical activity in elderly mammals and mammals with sarcopenia.

DETAILED DESCRIPTIONIt is to be understood by one of ordinary skill in the art that the present discussion is a description of exemplary embodiments only, and is not intended as limiting the broader aspects of the present disclosure.
The present disclosure is directed to a method and composition for increasing muscle protein synthesis and/or functional strength in mammals. As will be explained below, the present disclosure is generally directed to a protein building composition that when administered to a mammal in an effective amount preserves or increases muscle mass and function by increasing muscle protein synthesis and/or functional strength and/or decreasing protein degradation. The present disclosure is further generally directed to administering to a mammal an effective amount of a protein building composition that increases muscle protein synthesis and/or functional strength.

In another particular embodiment, the dosage can be greater than about 1 milligrams per kilogram body weight per day, greater than about 5 milligrams per kilogram body weight per day, greater than about 10 milligrams per kilogram body weight per day, greater than about 15 milligrams per kilogram body weight per day, greater than about 20 milligrams per kilogram body weight per day, greater than about 30 milligrams per kilogram body weight per day, greater than about 40 milligrams per kilogram body weight per day, or greater than about 50 milligrams per kilogram body weight per day.
The protein building composition can be administered regularly, such as at least two to four times a week. For instance, the protein building composition may be administered to the mammal at least every one to three days. Further, the protein building composition may be administered more than one time per day. For instance, the protein building composition may be administered to the mammal one to four times per day. In one particular embodiment, the protein building composition is administered daily. The dosage can be from about 5 to 30,000 milligrams per day, such as from about 5 to about 20,000 milligrams per day, such as from about 10 milligrams to about 10,000 milligrams per day, such as from about 20 milligrams to about 5,000 milligrams per day, such as from about 50 milligrams to about 2,500 milligrams per day. Based on body mass, the dosage can be from about 1 milligram per kilogram of body weight per day to about 10,000 milligrams per kilogram body weight per day. For example, the dosage may be from about 5 milligrams per kilogram body weight per day to about 7,500 milligrams per kilogram body weight per day, such as from about 10 milligrams per kilogram body weight per day to about 5,000 milligrams per kilogram body weight per day, such as from about 15 milligrams per kilogram body weight per day to about 2,500 milligrams per kilogram body weight per day, such as from about 20 milligrams per kilogram body weight per day to about 1,000 milligrams per kilogram body weight per day, such as from about 25 milligrams per kilogram body weight per day to about 750 milligrams per kilogram body weight per day, such as from about 30 milligrams per kilogram body weight per day to about 500 milligrams per kilogram body weight per day, such as from about 35 milligrams per kilogram body weight per day to about 250 milligrams per kilogram body weight per day.
The protein building composition can be administered to the mammal in any suitable form using any suitable administration route. For example, the composition can be administered orally alone, in combination with a food composition, or as part of a food composition. The composition may also be part of a dietary supplement or as a nutraceutical composition.
The protein building composition can be administered orally as a solid, liquid, suspension, or gas. The composition may be administered via buccal or sublingual administration. In one embodiment, the protein building composition may be administered as a capsule, tablet, caplet, pill, troche, drop, lozenge, powder, granule, syrup, tea, drink, thin film, seed, paste, herb, botanical, and the like.
In addition to being administered orally, the supplement dose can also be administered using other routes including intranasal, intravenous, intramuscular, intragastric, and the like.
When the protein building composition is combined with a food or beverage composition, the food or beverage composition may comprise any suitable composition for consumption by the mammal. Such compositions include complete foods or beverages intended to supply the necessary dietary requirements for mammal or food supplements such as treats and snacks. The food composition may comprise pellets, a drink, a bar, a prepared food contained in a can, a milk shake drink, a juice, a dairy food product, or any other functional food composition. The food composition may also comprise any form of a supplement such as a pill, soft gel, gummy figurine, wafer, or the like.
A food composition ingested by the mammal in addition to the protein building composition may also be rich in L-carnitine, leucine, and/or creatine. The protein building composition of the present disclosure, for instance, is intended to provide additional L-carnitine, leucine, and/or creatine in addition to the normal amounts contained in a standard diet and/or the amounts produced by the body.
The mammal treated in accordance with the present disclosure can comprise any suitable mammal. For instance, the mammal may be human or canine. The protein building composition can be fed to a mammal of any age such as from parturition through the adult life in the mammal. In various embodiments the mammal may be a human, dog, a cat, a horse, a pig, a sheep, or a cow. In many embodiments, the mammal can be in early to late adulthood. For instance, the active mammal may have an age that is at least 10%, such as least 15%, such as least 20%, such as least 25%, such as least 30%, such as least 35%, such as least 40%, such as least 45%, such as least 50%, such as least 55%, such as least 60%, such as least 65%, such as least 70%, such as least 75%, such as least 85%, such as least 90%, such as least 95% of its expected life span. The mammal may have an age such that it is less than about 95%, such as less than about 90%, such as less than about 85%, such as less than about 80%, such as less than about 75%, such as less than about 70%, such as less than about 65%, such as less than about 60%, such as less than about 55%, such as less than about 50%, such as less than about 45%, such as less than about 40%, such as less than about 35%, such as less than about 30%, such as less than about 25%, such as less than about 20%, such as less than about 15%, such as less than about 10% of its expected life span. A determination of life span may be based on actuarial tables, calculations, or the like.
The protein building composition may be administered to the mammal according to the present disclosure regardless of the frequency, intensity, or type of physical activity performed by the mammal. The mammal may participate in physical activities with various MET values. In one embodiment, the mammal may regularly participate in light to intense physical activity. Light physical activity may have a MET of from about 3 MET to about 6 MET. Moderate physical activity may have a MET of from about 6 MET to about 10 MET. Intense physical activity may have a MET of about 10 MET or greater. In another embodiment, the mammal may infrequently participate in physical activity. In yet another embodiment, the mammal may lead a sedentary lifestyle, wherein the mammal may rarely or never participate in physical activity. In a sedentary lifestyle, a mammal may participate mainly or exclusively in sedentary activities.
The protein building composition may be administered to the mammal before, during, or after a period of physical activity. Alternately, the composition may be administered to the mammal before, during, or after a period of sedentary activity. For instance, the composition may be administered to the mammal during an extended period of bed rest or other extended period of inactivity.
The protein building composition is administered in an amount sufficient to increase muscle protein synthesis, increase functional strength, or increase both muscle protein synthesis and functional strength without requiring the mammal to participate in physical activity.
Muscle protein synthesis, in one embodiment, can be determined by monitoring the biomarkers, mTOR expression and phosphorylation and its related upstream and downstream proteins in the pathway, in skeletal muscle. Specifically, mTOR expression can be determined and recorded before and after a period of activity. For a mammal treated in accordance with the present disclosure, mTOR expression before and after a period of time may vary by more than 10%, such as by more than 20%, such as by more than 40%, such as by more than 60%, such as by more than 80%, such as by more than 100%, such as by more than 150%, such as by more than 200%.
In one embodiment, the mammals treated in accordance with the present disclosure may have total mTOR values after a period of activity that are at least 10%, such as at least 20%, such as at least 30%, such as at least 40%, such as at least 50%, such as at least 60%, such as at least 100% greater than the same mammal that is not administered the protein building composition.
Protein synthesis can be monitored by androgens, androgen receptors, insulin, IGF-1, IGF-1 receptors and any known stimulator of protein synthesis.
In addition to increased muscle protein synthesis, the protein building composition can also increase functional strength. In particular, the protein building composition can increase lean muscle mass and upper and lower body strength. Functional strength can be measured by a composite endpoint of strength and muscle measures. The composite endpoint may be the product of the values for muscle mass (kg), upper extremity strength by dynamometer (kg), lower extremity strength by dynamometer (kg), and 6-minute walk test (meters). Comparative measurements can be taken prior to and after a period of activity.
In one embodiment, mammals treated in accordance with the present disclosure may have composite endpoints after a certain period of time that are at least 10%, such as at least 25%, such as at least 50%, such as at least 75%, such as at least 100% more than the same mammal that is not administered the L-carnitine supplement.
The protein building composition of the present disclosure may also reduce inflammation. Inflammation, in one embodiment, can be determined by monitoring the biomarker, TNF-α, in skeletal muscle. TNF-α is an inflammatory marker involved in protein degradation. Reduction in TNF-α values may indicate a reduction in protein degradation and muscle wasting. TNF-α values can be determined and recorded before and after a period of activity. For a mammal treated in accordance with the present disclosure, TNF-α values before and after a period of time may vary by more than 0.5%, such as by more than 1%, such as by more than 5%, such as by more than 10%, such as by more than 20%, such as by more than 40%, such as by more than 60%, such as by more than 80%, such as by more than 100%, such as by more than 150%, such as by more than 200%.
In one embodiment, the mammals treated in accordance with the present disclosure may have total TNF-α values after a period of activity that are at least 0.5%, such as at least 1%, such as at least 5%, such as at least 10%, such as at least 20%, such as at least 30%, such as at least 40%, such as at least 50%, such as at least 60%, such as at least 100% less than the same mammal that is not administered the protein building composition.
Reduced inflammation can lead to decreased protein degradation.
In one embodiment, the compositions of the present disclosure may contain other amino acids, including but not limited to alanine, arginine, asparagine, aspartate, cysteine, glutamic acid, glutamine, glycine, proline, serine, tyrosine, histidine, isoleucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine, and any combinations thereof.
The protein building composition of the present disclosure may further comprise one or more excipients. Exemplary but non-limiting excipients include antiadherents, such as magnesium stearate; binders, such as saccharides, sugar alcohols, gelatin, and synthetic polymers; coatings, such as cellulose ether hydroxypropyl methylcellulose (HPMC), shellac, corn protein zein, gelatin, fatty acids, and waxes; coloring agents, such as titanium oxide and azo dyes; disintegrants, such as modified starch sodium starch glycolate and crosslinked polymers including polyvinylpyrrolidone and sodium carboxymethyl cellulose; fillers, such as maltodextrin; flavoring agents, such as mint, liquorice, anise, vanilla, and fruit flavors including peach, banana, grape, strawberry, blueberry, raspberry, and mixed berry; glidants, such as fumed silica, talc, and magnesium carbonate; lubricants, such as talc, silica, and fats including vegetable stearin, magnesium stearate, and stearic acid; preservatives, such as antioxidants, vitamins, retinyl palmitate, selenium, the amino acids cysteine and methionine, citric acid, sodium citrate, and parabens; sorbents; sweeteners, such as sucrose and sucralose; and vehicles, such as petrolatum and mineral oil.
In one embodiment, the protein building composition of the present disclosure may be combined with various additives and components that can improve one or more properties of the composition. For example, in one embodiment, the additive composition may be combined with a stabilizer package that may serve to stabilize at least one property of the composition. In one particular embodiment, for instance, a stabilizer package may be added to the composition in an amount sufficient to reduce the hydroscopic properties of the composition and/or prevent the composition from absorbing moisture. A stabilizer package may also be combined with the protein building composition in order to improve the handling properties of the composition. For instance, the stabilizer package may allow the composition to have better flow properties, especially when in granular form.
In one embodiment, the protein building composition may be combined with a polymer binder in conjunction with a stabilizer package. In addition, a coating material may also be applied to the composition after the composition has been combined with the polymer binder and the stabilizer package. The coating material, for instance, may contain at least one fat. In accordance with the present disclosure, the above components can be added to any suitable pharmaceutical composition in addition to the protein building composition of the present disclosure. For instance, the above components may be added to any pharmaceutical composition containing a carnitine or an amino acid.
The polymer binder and the stabilizer package may be combined with the protein budding composition in a manner that homogeneously incorporates the stabilizer package into the product. In one embodiment, for instance, the protein building composition of the present disclosure is first combined with a polymer binder, such as through a spray dry process, and then combined with the stabilizer package. The polymer binder may comprise any suitable pharmaceutically acceptable polymer, such as film-forming polymers and/or polysaccharides. Particular examples of polymer binders that may be used in accordance with the present disclosure include starch, maltodextrin, gum arabic, arabinogalactan, gelatin, and mixtures thereof. In one embodiment, the polymer binder is added to the pharmaceutical composition in an amount of at least about 5% by weight, such as at least about 8% by weight, such as at least about 10% by weight, such as at least about 15% by weight. One or more polymer binders are present in the composition in an amount less than about 50% by weight, such as in an amount less than about 45% by weight, such as in an amount less than about 40% by weight, such as in an amount less than about 35% by weight, such as in an amount less than about 30% by weight.
In one embodiment, the polymer binder may comprise a starch, such as a modified starch. The starch, for instance, may be derived from corn or waxy maize. In one embodiment, the starch may comprise HI-CAP100 starch sold by National Starch and Chemical Company.
In an alternative embodiment, the polymer binder may comprise arabinogalactan. Arabinogalactan is a soluble polysaccharide that not only can serve as a polymer binder but may also provide other benefits. For instance, arabinogalactan may enhance the adaptive immune response in some circumstances. Arabinogalactan is described, for instance, in U.S. Pat. No. 8,784,844, which is incorporated herein by reference.
In one embodiment, larch arabinogalactan may be used as the polymer binder. Larch arabinogalactan is a highly branched polysaccharide that is composed of galactose units and arabinose units in the approximate ratio of 6:1. Larch arabinogalactan is extracted from large trees. The polysaccharide has a galactan backbone with side chains of galactose and arabinose. Arabinogalactan is commercially available from Lonza Ltd.
Once the polymer binder is combined with the protein building composition such as through a spray dry process, the resulting mixture can then be combined with a stabilizer package. In one embodiment, the stabilizer package comprises oxide particles in combination with a salt of a carboxylic acid. In one particular embodiment, the stabilizer package may comprise a dry product, such as a powder or granular product that is combined with the protein building composition and polymer binder. The combination of oxide particles and a salt of a carboxylic acid have been found to provide numerous advantages and benefits when combined with the protein building composition. For instance, the stabilizer package has been found to stabilize the protein building composition and make the composition less hydroscopic. The composition is also easier to handle and, when in granular form, produces a free-flowing product.
The oxide particles that may be added to the pharmaceutical composition may comprise silica. For instance, the oxide particles may comprise precipitated silica particles. The silica particles may have a particle size (d50, laser detraction following ISO Test 13320) of less than about 55 microns, such as less than about 40 microns, such as less than about 30 microns, such as less than about 25 microns, such as less than about 20 microns, such as less than about 15 microns, such as less than about 12 microns, such as less than about 10 microns, such as less than about 8 microns, such as less than about 6 microns, such as less than about 4 microns, such as less than about 2 microns, such as less than about 1 micron. The particle size is typically greater than about 0.5 microns, such as greater than about 1 micron. The particles may have a specific surface area (ISO Test 9277) of greater than about 120 m2/g, such as greater than about 130 m2/g, such as greater than about 150 m2/g, such as greater than about 170 m2/g, such as greater than about 200 m2/g, such as greater than about 220 m2/g. The specific surface area is generally less than about 500 m2/g. The oxide particles, such as the silica particles, can be present in the pharmaceutical composition in an amount greater than about 0.01% by weight, such as in an amount greater than about 0.05% by weight, such as in an amount greater than about 0.1% by weight. The oxide particles are generally present in an amount less than 5% by weight, such as in an amount less than about 2% by weight, such as in an amount less than about 1.5% by weight, such as in an amount less than 0.5% by weight.
In addition to the oxide particles, the stabilizer package may also include a salt of a carboxylic acid. The salt of a carboxylic acid may comprise a salt of a fatty acid. The fatty acid, for instance, may have a carbon chain length of from about 6 carbon atoms to about 40 carbon atoms, such as from about 12 carbon atoms to about 28 carbon atoms. In one embodiment, the salt of the carboxylic acid may comprise a stearate salt. The stearate salts that may be used include calcium stearate, sodium stearate, magnesium stearate, mixtures thereof, and the like. In one embodiment, the salts of the carboxylic acid may include both hydrophilic groups and hydrophobic groups. The salt of the carboxylic acid may be present in the pharmaceutical composition in an amount greater than about 0.5% by weight, such as in an amount greater than about 1% by weight, such as in an amount greater than about 1.5% by weight. The salt of the carboxylic acid is generally present in an amount less than about 5% by weight, such as in an amount less than about 4% by weight, such as in an amount less than about 3% by weight.
In addition to the polymer binder and the stabilizer package, the composition may include various other components and ingredients. In one embodiment, for instance, the composition may contain a citric acid ester, such as a citric acid ester of a mono and/or diglyceride of a fatty acid. The composition may also contain a lecithin, such as a lecithin obtained from rapeseed, sunflower, and the Ike. The above components can be present in the composition in relatively minor amounts, such as less than about 2% by weight, such as less than about 1.5% by weight, such as less than about 1% by weight. The above components are generally present in an amount greater than about 0.05% by weight, such as in an amount greater than about 0.1% by weight.
Once the above components are combined together to form the pharmaceutical composition, the composition can optionally be combined with a coating material. In one embodiment, for instance, the pharmaceutical composition may comprise a granular composition to which a coating material is applied that contains a fat. The coating material, for instance, may comprise a hydrogenated oil, such as hydrogenated palm oil. In one particular embodiment, the coating material may comprise hydrogenated palm oil combined with palm stearine. In one embodiment, the hydrogenated oil may be present in the pharmaceutical composition in an amount from about 5% to about 35% by weight. The palm stearine, on the other hand, may be present in the pharmaceutical composition in an amount from about 2% to about 10% by weight. When present together, the weight ratio between the hydrogenated palm oil and the palm stearine may be from about 10:1 to about 1:1, such as from about 6:1 to about 2:1. In one embodiment, the hydrogenated palm oil and the palm stearine are present at a weight ratio of about 4:1.
The present disclosure may be better understood with reference to the following examples.
Example No. 1A randomized, double-blind, placebo-controlled study was conducted to evaluate the effects of two protein building compositions formulated according to the present disclosure on muscle protein synthesis, functional strength, lean body mass, and overall quality of life in healthy older adults.
The study was conducted with a sample size of 42 healthy older adults, with 14 subjects randomized to each study arm in a double-blind manner at a ratio of 1:1:1. Each subject was selected for compliance with the inclusion and exclusion criteria shown in Tables 1 and 2.
Table 1. Inclusion Criteria For Test SubjectsHealthy male or female adults, aged 55 to 70 years
BMI of 21 kg/m2 to 33 kg/m2
Subjects in good physical condition such that they can perform exercise testing safely, as determined by the Qualified Investigator based on medical history, physical examination, electrocardiogram and laboratory results
Subjects who are sedentary and not currently engaging in any regular exercise.
Subjects who agree to maintain their current level of activity and current dietary habits throughout the trial period.
Subjects who have given voluntary, written, informed consent to participate in the study.
The compositions of the three nutritional supplements are shown in Table 3. Subjects received one of the three supplements based on whether they were in the Sample 1, Sample 2, or the placebo group. The Sample 1 group received 4 grams of the designated composition per day. The Sample 2 group received 8 grams of the designated composition per day. The placebo group received 3 grams of the designated composition per day. Subjects were instructed to empty the contents of the sachet of the designated composition into one bottle of orange juice and shake vigorously for 1 min, then drink the entire bottle. Each sachet for Sample 1 and Sample 2 contained 2.2 g of L-carnitine tartrate. Subjects were instructed to start taking the product the day after randomization (Day 1). The subjects continued to take the product for an 8 week period.
Subjects were asked to maintain their current physical activity levels and dietary habits throughout the trial.
Assessments were conducted at Day 0, Day 29±3, and Day 57±3 of the study. On Day 29, subjects were contacted via phone to monitor adverse events and changes in concomitant medications as well as to foster compliance with the study dosing regimen.
Data was analyzed for the per protocol population, which consisted of all participants who consumed at least 80% of treatment or placebo doses, did not have any major protocol violations and completed all study visits and procedures connected with measurement of the primary variable. The per-protocol population contained 39 subjects, as 3 subjects were excluded from the original 42 subject population for protocol violations. For statistical analysis, within-group changes over 8 weeks of supplementation, and pre-to-post-strength testing changes, were tested for significance by the paired Student t test or the non-parametric Wilcoxon Signed-ranks test. Between-group differences in 8-week changes were tested for significance by the unpaired Student t test or the non-parametric Mann-Whitney U test. In the following tables, treatment groups with differing letter superscripts are significantly different. Probability values P≤0.05 are statistically significant.
Total lean mass was measured for each participant on Day 0 and Day 57±3 via dual-energy X-ray absorptiometry (DXA). As shown in
As revealed in
Illustrated in
Lower leg strength was assessed by average leg dynamometry for each participant on Day 0 and Day 57±3. As shown in
The participants completed the six minute walk test on Day 0 and Day 57±3. Table 6 shows that participants taking placebo had a significant reduction in their out of breath score after walking at the end of study relative to baseline (−0.43, P<0.05). There were no notable changes in the total meters walked, out of breath score before walking, and fatigue score before/after walking in all treatment groups.
Quality of life was determined by the participants' responses to the RAND SF-36 questionnaire on Day 0 and Day 57±3 shown in Table 7. The SF-36 questionnaire was developed at RAND as part of the Medical Outcomes Study. The Sample 1 group showed a trend towards increasing their energy/fatigue ratio (+6.1, P=0.073) by the end of the study relative to baseline. All other quality of life measures, including physical functioning, role functioning (physical or emotional), emotional well-being, social functioning, pain, and general health were not significantly changed by any intervention.
For mRNA analysis, muscle biopsies were taken from participants (n=38) at Day 0 and at Day 57±3 to evaluate the effect of Sample 1 and 2 or placebo on mRNA expression levels within the Ubiquitin-proteasome pathway, growth factor/protein signaling, and pro-inflammatory signaling pathways. mRNA was isolated from muscle tissue collected at baseline and end-of-study. From the mRNA, cDNA was synthesis and analyzed using RT-PCR techniques. Anabolic/protein synthesis signaling genes (androgen receptor, insulin receptor, IGF-1 & IGF-1 receptor), catabolic/protein degradation signaling genes (atrogin-1 & MuFR1) and cytokines/cytokine receptors (IL-6, IL-6 receptor, TNFα, TNFrSF1A, TNFrSF1B) genes were assayed along with GAPDH as the endogenous control. The mRNA expression for the muscle biopsies collected suggests that the Samples affect both the anabolic and catabolic pathways.
For the growth factor/protein signaling genes, Table 8 reveals that there were no significant between group differences observed; however, there was a trend for both Carnitine groups to have greater transcription of these genes compared to placebo.
The subject number (N=38) for Table 8 is reflected by the processing and isolation of mRNA from subjects' muscle biopsies taken on Day 0 and Day 57±3. Baseline and end of study muscle samples were required for this analysis (to see relative changes in the requested markers) and some of the subjects did not have enough skeletal muscle to yield the amount of mRNA required to run the molecular analysis.
The muscle biopsies taken on Day 0 and Day 57±3 from participants (n=33) were used to evaluate the effect of Sample 1 and 2 or placebo on protein expression/activity of the mTOR/S6K/4EBP1 protein synthesis and NFκβ (p65/p50) pro-inflammatory signaling pathways. Protein was isolated from muscle tissue collected at baseline and end-of-study, when pre- and post-exercise biopsies were collected. Post-exercise muscle biopsies were obtained approximately 1h following the pre-exercise biopsies. Western blotting was done with equal concentrations (40 μg) of protein separated on 8-12% SDS-PAGE gels, which were then transferred onto nitrocellulose membranes, and immune-labeled with antibodies specific to each protein of interest. Detection of these antibodies was done using enhanced chemiluminescence (ECL).
As shown in Table 9, there were notable changes in the muscle protein levels of participants taking Sample 1 and Sample 2 from week 0 (baseline) to week 8 (end of study) pre-exercise. In Table 9, in order to minimize variability between runs, the areas under of the curve were standardized relative to the micrograms of protein.
As shown in Table 9 and
As illustrated in
As shown in
In
The subject number (N=33) for Table 9 is reflected by the processing and isolation of protein from subjects muscle biopsies. Baseline and end of study muscle samples were required for this analysis (to see relative changes in the requested markers) and some of the subjects did not have enough skeletal muscle to yield the amount of protein required to run the molecular analysis.
Anthropometrics and vital signs were taken for each participant prior to Day 0 and on Day 57±3. As seen in Table 10, there were no significant between-group differences for both systolic and diastolic blood pressure as well as heart rate, weight, and BMI for all post randomization time points. Within groups, there was a significant change in diastolic blood pressure for the Sample 1 group, as well as mean heart rate in the Sample 2 group relative to baseline. All blood pressure and heart rate values were within acceptable clinical range.
Blood samples were taken for each participant taken prior to Day 0 and on Day 57±3 to measure hematology and clinical chemistry parameters. Table 11 demonstrates that there were no significant between group changes in hematology and clinical chemistry parameters for participants, with the exception of creatinine (P=0.027), estimated globular filtration rate (P=0.029), and aspartate transaminase (P=0.034) concentrations. However, these markers remained within their established clinical reference ranges.
There were five safety parameters that showed significant within group change from screening to the end of study (week 8). White blood cell count (P=0.021), lymphocyte count (P=0.022), and aspartate transaminase levels (P=0.033) increased for subjects on Sample 1, while chloride levels decreased significantly (P=0.013) for this group. The creatinine concentration (P=0.05) was significantly increased for the Sample 2 group. Estimated globular filtration rate (P=0.069) was not significantly changed for subjects within the Sample 2 group. Overall, all hematological and clinical parameters were within acceptable clinical range for this population.
A model was run on creatinine concentration with compliance, treatment group and their interaction as covariates. Table 12 reveals that compliance was not related to creatinine concentration.
The primary endpoint was a composite endpoint of the changes in Lean Body Mass (as assessed by DXA scan) and functional muscle strength (as assessed by 6 Minute Walk Test, Lower Body Dynamometry and Upper Body Dynamometry) of subjects administered Sample 2 compared to those administered placebo from baseline to week 8. The composite endpoint was calculated by multiplying the results of each component score (kg lean muscle mass×meters walked×kg resistance lower body×kg resistance upper body) to derive a composite score (expressed in arbitrary units). The percent change in composite score between baseline and week 8 was derived for comparison between Sample 2 and Placebo.
As revealed in
As described above, in one embodiment, the protein building composition of the present disclosure may be combined with a stabilizer package for improving one or more properties of the composition. The following example provides exemplary formulations, but is not intended to limit the invention. In fact, the stabilizer package and the process for incorporating the stabilizer package into the composition may be used in any suitable pharmaceutical composition and may not be limited solely to the protein building composition of the present disclosure.
In one embodiment, the following components may be first mixed together. The components include a protein building composition in accordance with the present disclosure combined with a polymer binder. In Sample No. 1, the polymer binder is modified starch. In Sample No. 2, the polymer binder is larch arabinogalactan. The below components can be spray dried into a granule to form a granular product. For instance, the spray pressure can be about 2 bar while the spray rate can be from about 10 to about 20 grams per minute.
After the above granular product is produced, the product can be mixed with a stabilizer package. The stabilizer package may comprise a dry mix of calcium stearate and silica. The calcium stearate can be added in an amount of about 2.5% by weight, while the silica may be added in an amount of about 0.2% by weight. Because the stabilizer package is a dry mix, a pharmaceutical composition is produced that comprises a granular mixture. The stearate and silica serve to stabilize the granular particles.
To the granular mixture, a fat coating material can be applied. The fat coating material may comprise a combination of hydrogenated palm oil and palm stearine. In one embodiment, hydrogenated palm oil is added in an amount of 16% by weight, while palm stearine is added in an amount of 4% by weight of the resulting pharmaceutical composition. In an alternative embodiment, the hydrogenated palm oil is added in an amount of 24% by weight, while the palm stearine is added in an amount of 6% by weight of the pharmaceutical composition.
These and other modifications and variations to the present invention may be practiced by those of ordinary skill in the art, without departing from the spirit and scope of the present invention, which is more particularly set forth in the appended claims. In addition, it should be understood that aspects of the various embodiments may be interchanged both in whole or in part. Furthermore, those of ordinary skill in the art will appreciate that the foregoing description is by way of example only, and is not intended to limit the invention so further described in such appended claims.
