REDUCTION OF ADVANCED GLYCATION ENDPRODUCTS FROM BODILY FLUIDS
The invention concerns removing advanced glycation end products from a bodily fluid by contacting the bodily fluid with a sorbent.
The present application claims benefit of U.S. Patent Application No. 62/552,424 filed on Aug. 31, 2017, the disclosure of which is incorporated herein in its entirety.
TECHNICAL FIELDThe invention concerns reduction of advanced glycation end products from bodily fluids.
BACKGROUNDDegenerative diseases as well as aging are mainly based on a life-long accumulation of molecular damages within molecules, cells and tissues. Important examples of damaging structures are the advanced glycation end products (AGEs).
Advanced glycation end products (AGEs), pathophysiological important posttranslational modifications, are formed in vivo by a non-enzymatic reaction of proteins with reactive carbohydrates and accumulate during aging. They are discussed to be responsible for degenerative diseases. Glycation modifies the structure and function of proteins and induces tissue stiffening via crosslinking. Soluble AGEs can bind to receptors like the receptor for advanced glycation end products (RAGE). Binding to RAGE induces on the one hand the expression of RAGE itself and on the other hand, the expression of proinflammatory cytokines leading to a long-lasting inflammatory response. This may have an impact on aging, as aging is mostly connected to inflammation (Inflammaging). RAGE-knock out mice are protected in models of sepsis (increased survival). In the cardiovascular system, AGEs are a major cause of cardiac and vascular dysfunction.
High levels of AGEs have been linked with the development of a variety of diseases including diabetes, heart disease, kidney failure, Alzheimer's and macular degeneration. There is a need in the art for methods that treat, prevent or low the progression of diseases associated with AGEs.

The present invention does not rely on charge or a ligand-receptor complex binding reaction to inhibit or reduce pathogen toxicity. A polymer using acid functional group(s) attached to the polymer backbone to bind Clostridium difficile Toxin A and Toxin B is described by Bacon Kurtz et al. (U.S. Pat. No. 6,890,523). The interaction in Kurtz is ionic where a hydrophobic or hydrophilic group attached to the polymer binds the toxin. Chamot et al. (US Patent Application 2006/009169) describe using inorganic polymer particles linked to a toxin binding moiety comprised of oligosaccharide sequences that bind C. difficile Toxin A and Toxin B. Also described is a toxin binding surface pore size 2× larger than toxin diameter. Chamot described oligosaccharide moieties that bind toxins to form a ligand/receptor-like complex.
The polymer materials used as the sorbent are generally not metabolizable by human and animal, but may be synthesized from materials characterized as being a biodegradable polymer, a resorbable polymer, or both. Certain polymers may be irregular or regular shaped particulates such as powders, beads, or other forms with a diameter in the range of 0.1 micron meters to 2 centimeters.
The polymers used in the instant invention preferably have a biocompatible and hemocompatible exterior surface coatings but are not absolutely necessary, especially in certain circumstances, such as oral or rectal administration. Certain of these coatings are covalently bound to the polymer particle (beads, for example) by free-radical grafting. The free-radical grafting may occur, for example, during the transformation of the monomer droplets into polymer beads. The dispersant coating and stabilizing the monomer droplets becomes covalently bound to the droplet surface as the monomers within the droplets polymerize and are converted into polymer. Biocompatible and hemocompatible exterior surface coatings can be covalently grafted onto the preformed polymer beads if the dispersant used in the suspension polymerization is not one that imparts biocompatibility or hemocompatibility. Grafting of biocompatible and hemocompatible coatings onto preformed polymer beads is carried out by activating free-radical initiators in the presence of either the monomers or low molecular weight oligomers of the polymers that impart biocompatibility or hemocompatibility to the surface coating.
Porogens that may be used in the invention may be one or more of benzyl alcohol, cyclohexane, cyclohexanol, cyclohexanol/toluene mixtures, cyclohexanone, decane, decane/toluene mixtures, di-2-ethylhexylphosphoric acid, di-2-ethylhexyl phthalate, 2-ethyl-1-hexanoic acid, 2-ethyl-1-hexanol, 2-ethyl-1-hexanol/n-heptane mixtures, 2-ethyl-1-hexanol/toluene mixtures, isoamyl alcohol, n-heptane, n-heptane/ethylacetate, n-heptane/isoamyl acetate, n-heptane/tetraline mixtures, n-heptane/toluene mixtures, n-hexane/toluene mixtures, pentanol, poly(styrene-co-methyl methacrylate)/dibutyl phthalate, polystyrene/2-ethyl-1-hexanol mixtures, polystyrene/dibutyl phthalate, polystyrene/n-hexane mixtures, polystyrene/toluene mixtures, toluene, tri-n-butylphosphate, 1,2,3-trichloropropane/2-ethyl-1-hexanol mixtures, 2,2,4-trimethyl pentane (isooctane), trimethyl pentane/toluene mixtures, poly(propylene glycol)/toluene mixtures poly(propylene glycol)/cyclohexanol mixtures, and poly(propylene glycol)/2-ethyl-1-hexanol mixtures.
The present biocompatible sorbent compositions are comprised of a plurality of pores. The biocompatible sorbents are designed to adsorb a broad range of toxins from less than 1 kDa to 1,000 kDa. While not intending to be bound by theory, it is believed the sorbent acts by sequestering molecules of a predetermined molecular weight within the pores. The size of a molecule that can be adsorbed by the polymer will increase as the pore size of the polymer increases. Conversely, as the pore size is increased beyond the optimum pore size for adsorption of a given molecule, adsorption of the protein may or will decrease.
In one embodiment a porous polymer that absorbs small to midsize protein molecules equal to or less than 50,000 Daltons (50 kDa) and excludes absorption of large blood proteins comprises the pore structure such that the total pore volume of pore size in the range of 50 Å to 40,000 Å are in the range of 0.5 cc/g to 5.0 cc/g dry sorbent. The sorbent has a pore structure such that the total pore volume of pore size in the range of 50 Å to 40,000 Å is greater than 0.5 cc/g to 5.0 cc/g dry sorbent; wherein the ratio of pore volume between 50 Å to 40,000 Å (pore diameter) to pore volume between 100 Å to 1,000 Å (pore diameter) of the sorbent is smaller than 3:1.
In another embodiment a porous polymer that optimally absorbs midsize to large size protein molecules of approximately 300,000 Daltons and excludes or minimizes absorption of very large blood proteins comprises the pore structure such that the total pore volume of pore size in the range of 50 Å to 40,000 Å are in the range of 0.5 cc/g to 5.0 cc/g dry sorbent. The sorbent has a pore structure such that the total pore volume of pore size in the range of 50 A to 40,000 Å is greater than 0.5 cc/g to 5.0 cc/g dry sorbent; wherein the ratio of pore volume between 50 Å to 40,000 Å (pore diameter) to pore volume between 1,000 Å to 10,000 Å (pore diameter) of the sorbent is smaller than 2:1.
In another embodiment a porous polymer that optimally absorbs very large size protein molecules equal to or less than 1,000,000 Daltons and excludes or minimizes absorption of very large blood proteins comprises the pore structure such that the total pore volume of pore size in the range of 50 Å to 40,000 Å are in the range of 0.5 cc/g to 5.0 cc/g dry sorbent. The sorbent has a pore structure such that the total pore volume of pore size in the range of 50 Å to 40,000 Å is greater than 0.5 cc/g to 5.0 cc/g dry sorbent; wherein the ratio of pore volume between 50 Å to 40,000 Å (pore diameter) to pore volume between 10,000 Å to 40,000 Å (pore diameter) of the sorbent is smaller than 3:1.
TreatmentsDegenerative diseases as well as aging are believed to mainly be based on a life-long accumulation of molecular damages within molecules, cells and tissues. An important example of damaging structures are the advanced glycation end products (AGEs). It is believed that AGEs may be related to many degenerative diseases. Illustrative degenerative disease are Alzheimer's disease, macular degeneration, osteoarthritis, atherosclerosis, heart disease and kidney failure. The instant methods and sorbents may be useful in treatment of the disease or may be used prophylactically.
The sorbent may be contained in a cartridge and the bodily fluid treated ex vivo. For example, blood or other bodily fluid is pumped out of the body, directly through a CytoSorb™ hemoperfusion cartridge where the beads remove AGEs, and the purified fluid is then pumped back into the body.
In some embodiments, the bodily fluid comprises saliva, nasopharyngeal fluid, blood, plasma, serum, saliva, gastrointestinal fluid, bile, cerebrospinal fluid, pericardial, vaginal fluid, seminal fluid, prostatic fluid, peritoneal fluid, pleural fluid, urine, synovial fluid, interstitial fluid, intracellular fluid, extracellular fluid, lymph, mucus, or vitreous humor.
In other embodiments, the treatment may be in vivo. For example, the compositions may be given orally, rectally or via a feeding tube. The sorbent can be supplied as a dry powder or other dry particulate capable of being wetted externally or internally in the alimentary canal, including in the gastric or enteric environment, with or without the addition of wetting agents such as ethyl or isopropyl alcohol, potable liquids such as water, or other carrier fluid. Other possible routes of administration include subcutaneous or transdermal delivery. In some embodiments, administration is topical. Such methods include ophthalmic administration, administration to skin or wounds, direct administration into a body cavity or joint, and delivery to mucous membranes such as nasal, oral, vaginal and rectal delivery or other delivery to the alimentary canal. In some embodiments, the treatment is extracorporeal. Extracorporeal administration would include removal of inflammatory mediators from blood or physiologic fluids by circulating the fluids through a device containing sorbent and returning it back to the body. In some embodiments, such methods include local or systemic administration through a parenteral route. Parenteral administration includes intravenous, intraarterial, subcutaneous, intraperitoneal or intramuscular injection or infusion; or intracranial (including intrathecal or intraventricular, administration).
The sorbent may be formulated as for example, a powder, a tablet, a capsule, a solution, a slurry, an emulsion, a suppository, or in a food substance. The sorbent may be packaged in portable bottles, vials, blister packs, bags, pouches, or other container that allows for either single or multiple dosages. Depending on the use, the sorbent may be sterile or non-sterile. The polymer may be sterilized by standard methods. Such methods are well known to those skilled in the art. The therapeutically effective amount can be administered in a series of doses separated by appropriate time intervals, such as hours. The compositions of the instant invention may be administered by methods well known to those skilled in the art.
EXAMPLESThe following examples are intended to be illustrative and non-limiting.
Example 1Plasma samples were treated with Aspirin/Glucose or both to induce posttranslational modifications. Samples were used directly (−) or after passage through a CytoSorbents adsorber (+), separated by gel electrophoresis, blotted and stained with antibodies against Acetyllysine or Carboxymethyllysine (CML, advanced glycation end product, AGE).
This example utilizes a protein (25 kD) and stains CML green and Acetyllysine red (Odyssee system). In
It is observed that sorption of AGE molecules having a molecular weight of 80 or 100 or 120 kDa or more may be achieved by contacting bodily fluid with the instant sorbents.
