Rexahn Pharmaceuticals, Inc. (NYSE MKT: RNN), a clinical stage biopharmaceutical company, announced today that it has signed an exclusive license agreement with the University of Maryland, Baltimore (UMB) for a novel drug delivery platform, Nano-Polymer-Drug Conjugate Systems (NPDCS). This technology targets the delivery of currently marketed chemotherapeutic agents directly into cancerous tumors. The direct delivery of chemotherapeutic drugs into the tumors has been shown to result in increased efficacy and reduced toxicity.
The NPDCS platform combines existing chemotherapeutic agents with a proprietary polymer carrier that contains a signaling moiety which directs the drug into the tumor. This approach minimizes the levels of freely circulating anti-cancer agents in the body, which can dramatically reduce potential adverse events, and maximizes anti-tumor activity by accumulating in the cancer tumor. NPDCS is a broad platform that has the potential to generate multiple therapeutic candidates going forward.
