Abstract (en)

[origin: WO2019178359A1] Stable aqueous gel or semisolid gel pharmaceutical composition comprising a gel-forming and water-soluble peptide are optionally combined with an appropriate excipient and a therapeutic agent. The pharmaceutical composition forms a gel depot following administration to an individual, where the gel nanostructure releases the peptide or the encapsulated therapeutic agent(s) over a extended period of time. The gel-forming compounds can be formulated in aqueous, suspension, or solid formulations, comprising 0.01 % to 99% of a gel-forming polypeptide by weight with relation to the total weight of the formulation. These formulations are useful in drug delivery and as implantable drug depot for long term delivery of therapeutic agents, antigens, or cells. Also provided are methods of producing a gel-forming compound, through the modification of a chemical compound with a gel-forming enhancing motif.
