SAN DIEGO, Dec. 14 /PRNewswire-FirstCall/ -- Neurocrine Biosciences, Inc. announced today that its partner GlaxoSmithKline (GSK) has initiated a Phase I clinical trial with a lead Corticotropin Releasing Factor 1 (CRF1) receptor antagonist compound. The Phase I clinical trial is a double-blind, randomized, placebo controlled, single dose study to evaluate the safety and pharmacokinetics (PK) of a range of escalating doses of this compound in healthy volunteers. As part of their collaboration, Neurocrine and GSK are developing CRF antagonists for several indications including anxiety and depression.
"We are pleased to advance the GSK and Neurocrine collaboration's newest generation CRF1 antagonist into clinical development. This novel CRF1 antagonist lead compound was selected from several novel series of compounds discovered by GSK and Neurocrine, based on a rigorous preclinical safety and efficacy evaluation. Following completion of this initial Phase I clinical trial, we anticipate further evaluating this lead compound in extended Phase I and Phase II proof of concept trials," said Dr. Wendell Wierenga, Executive Vice President of Research and Development for Neurocrine Biosciences.
Dr. Wylie Vale, Neurocrine co-founder, first identified and cloned the CRF1 receptor along with his colleagues at the Salk Institute. Neurocrine further characterized the CRF receptor system and identified additional members of the CRF receptor family. CRF functions as a neurotransmitter in the brain and plays a critical role in coordinating the body's response to stress. The CRF1 receptor subtype largely mediates these effects. In preclinical models, selective CRF1 receptor antagonists block stress-related responses providing further evidence that this novel mechanism may result in improved anti-anxiety and anti-depressant properties. Neurocrine and GSK entered into a worldwide research, development and commercialization agreement in July 2001 for CRF receptor antagonists, to treat psychiatric, neurological and gastrointestinal diseases including anxiety, depression, and irritable bowel syndrome.
