摘要: Provided herein are water-soluble prodrugs, compositions comprising such prodrugs, and related methods of making and administering the same. The prodrugs of the invention comprise a water-soluble polymer having three or more arms, at least three of which are typically covalently attached to an active agent, e.g., a small molecule. The conjugates of the invention provide an optimal balance of polymer size and structure for achieving improved drug loading, since the conjugates of the invention possess three or more active agents releasably attached to a multi-armed water-soluble polymer. The prodrugs of the invention are therapeutically effective, and exhibit improved properties in-vivo when compared to unmodified parent drug.

摘要: The present invention relates to novel compositions of therapeutic cyclodextrin containing polymeric compounds designed as a carrier for small molecule therapeutics delivery and pharmaceutical compositions thereof. These cyclodextrin-containing polymers improve drug stability and solubility, and reduce toxicity of the small molecule therapeutic when used in vivo. Furthermore, by selecting from a variety of linker groups and targeting ligands the polymers present methods for controlled delivery of the therapeutic agents. The invention also relates to methods of treating subjects with the therapeutic compositions described herein. The invention further relates to methods for conducting pharmaceutical business comprising manufacturing, licensing, or distributing kits containing or relating to the polymeric compounds described herein.

摘要: The present invention provides biodegradable polymer particle delivery compositions based on polymers, such as polyester amide (PEA) and polyester urethane (PEUR) polymers, that contain amino acids in the polymer. The polymer particle delivery compositions can be formulated as a liquid dispersion of polymer particles with the bioactive agents dispersed in the particle or conjugated attached to polymer molecules or particle surfaces. The bioactive agents can include drugs, polypeptides, DNA and cells for cell-based therapies using particles sized for local, mucosal or circulatory delivery. Methods of treating a disease by administering to a subject the polymer particle delivery composition, which incorporates a bioactive agent suitable for treatment of the disease, or its symptoms, are also included.
