Abstract

The invention features biodegradable polymers for the delivery of biologically active agents. The polymers include at least one biologically active agent covalently attached via a polyamide linker susceptible to selective hydrolysis by peptidase enzymes. Hydrolysis of the polyamide linker releases the biologically active agent in vivo.
