(NYSE MKT: RNN), a clinical stage biopharmaceutical company developing best-in-class therapeutics for the treatment of cancer, today announced that it was issued patent number 5749273 from the Japanese Patent Office entitled "Polymeric Systems for the Delivery of Anticancer Drugs" for the Company's novel CPMA drug delivery platform. This new CPMA drug delivery platform technology, developed by Rexahn, enables more precise, targeted delivery of anti-cancer drugs directly into cancer cells.

Suzdak, Chief Executive Officer. "Rexahn Pharmaceuticals is pleased to be at the forefront of the development of novel, targeted approaches to cancer treatment, which could yield meaningful improvements in quality of life for cancer patients." Dr. Suzdak continued, "Rexahn remains committed to ensuring the strongest possible intellectual property protection for our proprietary anti-cancer programs and platform technologies. We are pleased to be issued this latest patent, which expands our intellectual property estate and extends intellectual property protection for the CPMA platform."
