News Release - September 27, 2007
NeurogesX' NGX-4010 MAA Filed and Accepted for Review by EMEA for Treatment of Peripheral Neuropathic PainSAN CARLOS, Calif., Sept. 27 (HSMN NewsFeed) -- NeurogesX, Inc. (Nasdaq: NGSX ), a biopharmaceutical company focused on developing novel pain management therapies, today announced that the Marketing Authorization Application (MAA) submitted by NeurogesX for NGX-4010, the Company's lead product candidate for peripheral Neuropathic Pain, has been accepted for review by the European Medicines Agency (EMEA).
NGX-4010 is a dermal patch that has been studied successfully in three Phase 3 clinical trials in patients suffering from peripheral Neuropathic Pain conditions. Two Phase 3 clinical trials for the treatment of pain associated with postherpetic neuralgia (PHN) and one for the treatment of pain associated with painful HIV-distal sensory polyneuropathy (HIV-DSP) demonstrated that a single 30- or 60-minute treatment with NGX-4010 applied directly to the site of pain may provide pain relief for up to 12 weeks.
Completion of the acceptance period (or validation) signifies that the EMEA will now begin review of NeurogesX' MAA. The review process is being coordinated by the EMEA under the centralized procedure, which, if resulting in approval, provides one marketing authorization for all European Union (EU) Member States, as well as Iceland, Liechtenstein and Norway.
Dr. Jeffrey Tobias, Chief Medical Officer, commented, "We believe that the data included in our MAA filing, which includes data from more than 1,400 patients studied in our clinical trials, demonstrates the benefit of NGX-4010 in treating patients suffering from peripheral Neuropathic Pain."
Anthony DiTonno, Chief Executive Officer, said, "Validation of our MAA signifies a critical step in our worldwide NGX-4010 development strategy and we look forward to productive interactions with the EMEA in order to potentially gain marketing approval for this novel therapy. We also remain focused on securing a partnering relationship in Europe prior to market approval and are currently in active discussions with potential partners for the commercialization of NGX-4010 in Europe. In addition to our European filing, we anticipate filing a new drug application or (NDA) for marketing approval in the United States in 2008."
NeurogesX recently announced that its second Phase 3 trial of NGX-4010 in postherpetic neuralgia (PHN) met its primary and all of its secondary endpoints. In addition to the Company's PHN studies, NeurogesX has also conducted a successful Phase 3 clinical trial of NGX-4010 in painful HIV-DSP. As recently announced, the Company's second, ongoing confirmatory Phase 3 trial for this indication has reached full enrollment and top-line results are expected near the end of the first quarter of 2008. NGX-4010 has been granted orphan status and has received fast track designation from the U.S. Food and Drug Administration (FDA) for HIV-DSP.
NGX-4010 is a non-narcotic, locally-acting analgesic formulated in a dermal patch containing capsaicin, a highly selective TRPV1 agonist. Capsaicin is released from the patch and absorbed into the skin without significant absorption into the bloodstream. Accordingly, users of NGX-4010 may be able to avoid the systemic side effects of anti-convulsants, anti-depressants and opioids, including sedation and the potential for abuse and addiction associated with some of these drugs. NGX-4010 is administered in a physician's office in a non-invasive process. In three Phase 3 clinical trials, NGX-4010 has been shown to reduce peripheral Neuropathic Pain for up to 12 weeks.
About PHN and HIV-DSP
PHN is a painful condition affecting sensory nerve fibers. It is a complication of shingles, a second outbreak of the varicella-zoster virus, which initially causes chickenpox. Following an initial infection, some of the virus can remain dormant in nerve cells. Years later, age, illness, stress, medications or other factors that are not well understood can lead to reactivation of the virus. The rash and blisters associated with shingles usually heal within six weeks, but some people continue to experience pain for years thereafter. This pain is known as postherpetic neuralgia. PHN may occur in almost any area, but is especially common on the torso.
HIV-DSP is caused primarily by three factors: direct activation of cells known as sensory neurons by the HIV virus, the immune system's fight against the infection, and the drugs administered to treat HIV. Painful HIV-DSP is characterized by significant pain in the feet and hands.
