Abstract
Disclosed are water soluble compositions of paclitaxel and docetaxel formed by conjugating the paclitaxel or docetaxel to a water soluble polymer such as poly-glutamic acid, poly-aspartic acid or poly-lysine. Also disclosed are methods of using the compositions for treatment of tumors, auto-immune disorders such as rheumatoid arthritis. Other embodiments include the coating of implantable stents for prevention of restenosis.
Claims25
A method for treating cancer in a subject, comprising administering to a subject having cancer (i) a composition of a taxoid molecule conjugated to a water soluble polymer and (ii) radiation.
A method of enhancing the response of a tumor to irradiation, comprising:
- a) administering to a patient in need of such therapy a radiosensitizing amount of a pharmaceutical composition comprising paclitaxel, docetaxel, etoposide, teniposide, camptothecin or epothilone conjugated to a water soluble polyamino acid polymer and a pharmaceutically acceptable carrier;
- b) irradiating said tumor;
- wherein said polymer has a molecular weight of about 5000 to 100000 daltons conjugated paclitaxel or docetaxel have increased water solubility, efficacy and accumulation within a tumor compared with the corresponding unconjugated drugs.
