A drug conjugate is provided herein. The conjugate comprises a protein based recognition-molecule (PBRM) and a polymeric carrier substituted with one or more -LD-D, the protein based recognition-molecule being connected to the polymeric carrier by LP. Each occurrence of D is independently a therapeutic agent having a molecular weight ≦5 kDa. LD and LP are linkers connecting the therapeutic agent and PBRM to the polymeric carrier respectively. Also disclosed are polymeric scaffolds useful for conjugating with a PBRM to form a polymer-drug-PBRM conjugate described herein, compositions comprising the conjugates, methods of their preparation, and methods of treating various disorders with the conjugates or their compositions.

The present invention provides folate receptor binding ligand‐drug delivery conjugates having the formula (F) nL1L2D. The conjugates have high affinity to folate receptor‐positive tumor cells and low toxicity for normal cells. The present invention also relates to preparation methods for such conjugates, pharmaceutical compositions comprising such conjugates, and use of such conjugates for preparing anti‐tumor medicaments.
