This invention relates to biotechnology, more particularly, to water-soluble polymeric delivery systems for the imaging, evaluation and/or treatment of rheumatoid arthritis and other inflammatory diseases. Using modern MR imaging techniques, the specific accumulation of macromolecules in arthritic joints in adjuvant-induced arthritis in rats is demonstrated. The strong correlation between the uptake and retention of the MR contrast agent labeled polymer with histopathological features of inflammation and local tissue damage demonstrates the practical applications of the macromolecular delivery system of the invention.

Described herein are biodegradable drug delivery conjugates for effectively delivering bioactive agents to a subject. The drug delivery conjugates comprise a water-soluble high molecular weight linear biodegradable polymer backbone comprising a plurality of linear water-soluble polymeric segments connected to one another by a first (main-chain) cleavable linker, wherein a bioactive agent is covalently bonded to at least one water-soluble polymeric segment, at least one cleavable linker, or a combination thereof. The conjugates possess numerous advantages over prior art delivery conjugates. Also described herein are methods for making and using the conjugates.

Polymeric drug delivery conjugates and methods of making and using thereof

Conjugates of hydroxypropyl methacrylamide (HPMA)-derived copolymers having attached thereto TNP-470 and a high load (e.g., higher than 3 mol %) of alendronate (ALN), and processes of preparing same are disclosed. Conjugates of polymers or copolymers having attached thereto an anti-angiogenesis agent and an oligoaspartate bone targeting agent, and processes of preparing same, are further disclosed. Pharmaceutical compositions containing these conjugates and uses thereof in the treatment and monitoring of bone related disorders are also disclosed.

Colonic-targeted oral drug dosage forms composed of a drug confined within a crosslinked hydrogel that exhibits pH-dependent swelling and is composed of an ionizable comonomer such as acrylic acid, a nonionizable comonomer such as an acrylamide, and a crosslinking agent that contains an aromatic azobond. Selective drug release in the colon occurs by a combination of pH-dependent swelling of the hydrogel and degradation of the hydrogel by enzymatic cleavage of the azobonds by azoreductases.
