NeurogesX files NDA for dermal capsaicin patch

NeurogesX, a biopharmaceutical company, has submitted a new drug application to the FDA for approval to market its investigational product candidate, NGX-4010, for the management of pain due to postherpetic neuralgia.

NeurogesX anticipates that the application, which is subject to acceptance by the FDA, will be subject to a standard review with a Prescription Drug User Fee Act date in the second half of 2009.

NGX-4010, the company’s lead product candidate, is a dermal high-concentration capsaicin patch. The new drug application (NDA) submission is supported by two pivotal studies of NGX-4010 in patients with postherpetic neuralgia.

The results of these clinical trials show a statistically significant reduction in pain from baseline for up to 12 weeks after a single 60-minute application of the dermal patch. The NDA clinical package includes data on over 2,300 patients with neuropathic pain.

Anthony DiTonno, president and CEO of NeurogesX, said: “Our top priority is to secure marketing approval of NGX-4010 in both the US and Europe. With the submission of our NDA and the ongoing review of our marketing authorization application in the EU, from which we anticipate a decision in the first half of 2009, we look forward with excitement to the potential for approval and subsequent commercial launch of NGX-4010 in both the US and the EU.”
