AVANIR Initiates Phase III Clinical Trial of Neurodex for the Treatment of Diabetic Neuropathic Pain
SAN DIEGO, Jun 23, 2005 (BUSINESS WIRE) -- AVANIR Pharmaceuticals (AMEX:AVN) today announced the initiation of a double-blind, placebo-controlled, multicenter, Phase III clinical trial of Neurodex(TM) in patients with diabetic neuropathic pain. The randomized, placebo-controlled study will assess efficacy, overall safety and tolerability of AVANIR's investigational drug targeting central nervous system (CNS) receptors to treat diabetic neuropathic pain.
The 3-month study will assess the efficacy of Neurodex in relieving pain in adult patients with distal symmetrical diabetic neuropathy with daily pain in the lower extremities. The clinical trial will be conducted at 40 sites in the United States and will include assessment scales completed in the clinic and diary records to assess pain. Patients will be randomized to receive placebo or one of two dose levels of Neurodex.
The clinical trial protocol was reviewed by the U.S. Food and Drug Administration (FDA) through a special protocol assessment (SPA) process. An SPA is a binding agreement between the FDA and the sponsor of a clinical trial documenting that if the study endpoints are met, the results should be sufficient to support approval of a New Drug Application (NDA). AVANIR expects that this will be the first of two Phase III clinical trials needed to submit an NDA for Neurodex for this indication.
"AVANIR is committed to developing and commercializing Neurodex as the cornerstone of our CNS research and development program," said James E. Berg, Vice President of Clinical and Regulatory Affairs at AVANIR. "The results of our previous open-label study of Neurodex in patients with diabetic neuropathic pain were encouraging, and we are eager to explore the potential of Neurodex as a treatment for diabetic neuropathic pain in a larger placebo-controlled study. The goal is to be able to offer a new treatment option for diabetic patients with painful neuropathies."
The results of a four-week Phase II open-label dose escalation safety study of Neurodex in patients with diabetic neuropathic pain were reported in November at the 2004 annual meeting of the American Society of Regional Anesthesia and Pain Medicine. Study data showed that Neurodex(TM) was well tolerated up to the highest target dose, and patients reported decreased pain intensity from that reported at baseline (p less than 0.0001). The degree of pain relief increased with the duration of the open label study.
