Patent ID: 8197828

Claim:
A composition comprising a first hydrophobic drug, a second hydrophobic drug and a polymer conjugate, wherein: the polymer conjugate comprises a polymeric matrix that non-covalently entraps at least a portion of the first hydrophobic drug therein; the polymer conjugate comprises a recurring unit of the formula (I): wherein n is 1 or 2; each A 1 is independently oxygen or NR 5 , where R 5 is hydrogen or C 1-4 alkyl; and at least one of R 1 and R 2 is a group that comprises the second hydrophobic drug, wherein if only one of R1 and R2 is the group that comprises the second hydrophobic drug, the other one of R1 and R2 is selected from the group consisting of hydrogen, a C 1-10 alkyl group, a C 6-20 aryl group, an ammonium group, an alkali metal, a polydentate ligand, a polydentate ligand precursor with protected oxygen atoms, a group that comprises a targeting agent, a group that comprises an optical imaging agent, a group that comprises a magnetic resonance imaging agent, and a group that comprises a stabilizing agent.
