Abstract
Provided herein are implantable compositions and methods of use thereof for the local delivery of therapeutically active agents.
Claims

2 . The implantable composition of claim 1 , further comprising at least one excipient.
3 . The implantable composition of claim 1 , wherein the at least one polymer, at least one excipient, and therapeutically active agent are separate and distinct entities.
4 . The implantable composition of claim 2 , wherein the at least one polymer, therapeutically active agent, and at least one excipient are embedded in the matrix, coated on the matrix, embedded in and coated on the matrix, or covalently linked to the matrix.
5 . The implantable composition of claim 1 , wherein the matrix comprises a membrane or porous scaffold.
6 . The implantable composition of claim 1 , wherein the matrix is a non-woven polymer mesh.
7 . The implantable composition of claim 1 , wherein the matrix is a woven polymer mesh.
8 . The implantable composition of claim 1 , wherein the matrix is a biological matrix.
9 . The implantable composition of claim 1 , wherein the matrix is a biological matrix selected from collagen sheets, bovine pericardium, human or animal dura or the like.
10 . The implantable composition of claim 1 , wherein the matrix is a polymer matrix comprising one or more of poly(ethylene), poly(propylene), poly(tetrafluroethylene), poly(methymethacrylate), ethylene-co-vinylacetate, poly(dimethylsiloxane), poly(ether-urethanes), polycarbonate, polyethersulphone, polybenzimidazole, acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC), polyether ether ketone (PEEK), poly(ethylene terphthalate), poly(sulphone), poly(esters) based on polylactide (PLA), polyglycolide (PGA), polycaprolactone (PCL), poly(hydroxyalkanoate)s, poly(saccharide)s, their copolymers and blends or combinations of copolymers and blends.
11 . The implantable composition of claim 1 , wherein the matrix is a polymer matrix comprising polyglycolic acid (PGA).
12 . The implantable composition of claim 3 , wherein the therapeutically active agent comprises about 50% by weight or less, or about 25% by weight or less of the total weight of the at least one polymer and at least one excipient embedded in the matrix, coated on the matrix, or embedded in and coated on the matrix.
13 . The implantable composition of claim 3 , wherein the therapeutically active agent comprises about 20% by weight or less of the total weight of the at least one polymer and at least one excipient embedded in the matrix, coated on the matrix, or embedded in and coated on the matrix.
