Amgen /Regeneron BDNF trial fails
THOUSAND OAKS, Calif., Jan 10 (Reuter) - Amgen Inc and Regeneron Pharmaceuticals Inc said the Phase III clinical trial of Brain-Derived Neurotrophic Factor (BDNF) failed to show clinical efficacy in patients with Lou Gehrig's disease. "While the trial confirmed the safety and tolerability seen in earlier trials, it showed no statistically significant or clinically relevant difference in breathing capacity or survival between treatment and placebo groups," the companies said in a statement. Lou Gehrig's Disease, also called amyotrophic lateral sclerosis (ALS) is a degenerative disease that attacks the nervous system and often renders patients unable to breathe. It afflicts between 20,000 and 40,000 people in the U.S. Amgen and Regeneron said they are continuing to study the efficacy of BDNF in treating Lou Gehrig's Disease when it is delivered intrathecally, or injected directly into the patient's spinal fluid. The trials for which results were announced Friday were based on subcutaneous, or regular, injection. The companies are also exploring BDNF as a treatment for diabetic neuropathy, another nervous system disorder. "We continue to believe that neurotrophic factors have potential to benefit patients with neurological diseases," Leonard Schleifer, Regeneron president and chief executive officer said in a statement. |
