Abstract

The present invention provides compositions comprising an anti-angiogenic factor, and a polymeric carrier. Representative examples of anti-angiogenic factors include Anti-Invasive Factor, Retinoic acids and derivatives thereof, and paclitaxel.

Claims

exact text as granted — not AI-modified
We claim:  
     
         1 . A composition, comprising: 
 (a) a compound which disrupts microtubule function; and    (b) a polymeric carrier, with the proviso that said polymeric carrier is not a capsule.    
     
     
         2 . The composition according to  claim 1  wherein said composition is formed into microspheres having an average size of between 0.5 and 200 μm.  
     
     
         3 . The composition according to  claim 1  wherein said composition is formed into a film with a thickness of between 100 μm and 2 mm.  
     
     
         4 . The composition according to  claim 1  wherein said polymeric carrier is copolymer of lactic acid and glycolic acid.  
     
     
         5 . The composition according to  claim 1  wherein said polymeric carrier is poly (caprolactone).  
     
     
         6 . The composition according to  claim 1  wherein said polymeric carrier is poly (lactic acid).  
     
     
         7 . The composition according to  claim 1  wherein said polymeric carrier is a copolymer of poly (lactic acid) and poly (caprolactone).  
     
     
         8 . The composition according to  claim 1  wherein said compound which disrupts microtubule function is paclitaxel.  
     
     
         9 . The composition according to  claim 1  wherein said compound which disrupts microtubule function is selected from the group consisting of estramustine, colchicine, methotrexate, curacin-A, epothilone, vinblastine and tBCEU.
