BioDelivery Sciences Announces Enrollment of the First Patient in a Phase 3 Clinical Study of Clonidine Topical Gel for Painful Diabetic Neuropathy
Product has fast track designation by FDA
Potential to be the first topical treatment approved for painful diabetic neuropathy
RALEIGH, N.C., April 3, 2014 /PRNewswire/ -- BioDelivery Sciences International, Inc. (Nasdaq: BDSI) announced today the enrollment of the first patient in the RHAPSODY Study, a Phase 3 clinical trial of Clonidine Topical Gel for the treatment of painful diabetic neuropathy.
The Phase 3 trial is a multicenter, randomized, double blind, placebo controlled study to determine the efficacy and safety of Clonidine Topical Gel in the treatment of pain associated with painful diabetic neuropathy. The study will be conducted in subjects demonstrating functional skin nociceptors, which is the population of patients that demonstrated a statistically significant difference compared to placebo on the primary efficacy endpoint in a previously conducted Phase 2 study. In the RHAPSODY Study subjects will be randomized to receive either Clonidine Topical Gel or a placebo gel. Approximately 140 adult subjects will be randomized into the study, which includes a double blind treatment phase of 12 weeks.
"We are very pleased to be moving another important clinical program into Phase 3 development," said Dr. Andrew Finn, Executive Vice President of Product Development. "There is a significant unmet need for new treatment options for patients suffering from painful diabetic neuropathy, and we look forward to progressing enrollment forward and toward anticipated interim results during the fourth quarter of this year followed by final study results in the first quarter of 2015."
"BDSI plans to conduct an independent interim analysis based on 50% of the patients completed," said Adrian Hepner, MD, Vice President of Clinical Research. "We anticipate that results of the interim analysis will be available in the fourth quarter of this year, and if the results confirm current study assumptions, the second Phase 3 trial of similar size and scope will be initiated at that time. This timeline could allow for a 2016 NDA submission."
BDSI met with representatives of the FDA on November 21, 2013 to discuss the proposed clinical development program for Clonidine Topical Gel for the treatment of painful diabetic neuropathy (also known as PDN). The FDA agreed with the overall clinical program proposed by BDSI, which includes two well controlled studies and one long-term safety study in patients suffering from painful diabetic neuropathy, the duration of treatment required for the safety assessment, the plan for data integration from prior and planned clinical studies and the interim analysis of the first pivotal trial. FDA also confirmed Fast Track designation for the program which recognizes the need of developing new therapies for this serious condition.
About Painful Diabetic Neuropathy and Topical Clonidine Gel
Nearly 26 million people in the U.S. have diabetes according to the American Diabetes Association. A substantial number of these people have peripheral neuropathy as manifest by impaired sensation and pain in the extremities, most often the feet. Patients with PDN often experience debilitating pain symptoms that affect day-to-day functioning and quality of life.
Clonidine Topical Gel is thought to relieve pain by decreasing the abnormal hyper-excitability of skin nociceptors. Currently available oral treatments are modestly effective in relieving symptoms and are limited by systemic side effects and drug interactions. There are no topical products approved for the treatment of this painful condition.
Oral medications that are approved for the treatment of painful diabetic neuropathy include anticonvulsants such as Lyrica (pregabalin), the antidepressant Cymbalta (duloxetine) and the opioid Nucynta (tapentadol), with sales for the treatment of neuropathic pain totaling over $3 billion in the U.S. according to Datamonitor. BDSI believes that Clonidine Topical Gel offers a novel mechanism of action to the available therapies with a potentially improved safety and tolerability profile. BDSI estimates annual peak sales potential for this product in excess of $300 million.
BDSI is the worldwide licensee of development and commercialization rights to Clonidine Topical Gel for painful diabetic neuropathy under a license with Arcion Therapeutics.
