NeurogesX Receives Notice of Two U.S. Patent Allowances Covering NGX-1998

SAN MATEO, Calif., Jun 19, 2012 (GlobeNewswire via COMTEX) -- NeurogesX, Inc. NGSX 0.00% , a specialty pharmaceutical company focused on developing and commercializing a portfolio of novel non-opioid, pain management therapies, today announced it has received two notices of allowance from the United States Patent and Trademark Office (USPTO) for patents covering NGX-1998, the Company's next generation liquid formulation of prescription strength capsaicin.

The first notice of allowance expands on NeurogesX' current patent entitled, "Methods and Compositions for Administration of TRPV1 Agonists," and includes claims that more specifically define the components of the liquid formulation of NGX-1998. The patent issuing from this application will have a term that expires in 2024.

The second notice of allowance is for the Company's patent entitled, "Compositions and Kits for the Removal of Irritating Compounds from Bodily Surfaces." This allowance includes claims relating to methods for removing capsaicin from the body using a surfactant-free, polyethylene glycol gel, and is complementary to the NGX-1998 patent family. The patent issuing from this application will have a term that expires in 2022.

"The two notices of allowance strengthen our U.S. patent estate for NGX-1998," Ronald Martell, President and CEO, commented. "Our Phase 2 data suggest that NGX-1998's product profile, including a five-minute application for up to three months of pain relief, make it an exciting advance in pain therapy. We are continuing our efforts to move into Phase 3 clinical trials as expeditiously as possible."

As previously announced, the Company expects to meet with the U.S. Food and Drug Administration (FDA) for an End of Phase 2 meeting in the third quarter of 2012. At the meeting, NeurogesX intends to discuss a 505(b)(2) clinical development program for NGX-1998 and gain greater clarity on the level of clinical data necessary for approval of NGX-1998. After the FDA meeting, the Company anticipates it will initiate a Phase 3 clinical trial by the end of 2012.
