About Rinat Neuroscience

Rinat Neuroscience Corporation operated as a privately held biotechnology firm focused on the discovery and development of antibody-based therapeutics for neurological disorders. The company was founded in 2001 by Arnon Rosenthal and Patrick Lynn. Dr. Rosenthal, an Israeli-American neuroscientist and biotechnology entrepreneur, served as the company's president and chief scientific officer. His background includes a Ph.D. from the Hebrew University of Jerusalem and a significant tenure at Genentech, where his work centered on the mechanisms controlling neuron survival and development. Rinat's inception was facilitated by a broad licensing agreement with Genentech, granting it access to key neuroscience assets.

The company's primary business was the research and development of protein-based therapeutics targeting significant unmet medical needs in the central nervous system. Rinat's strategy involved developing novel, disease-modifying therapies designed to modulate neuron function and reverse damage in specific disease states. Its portfolio addressed conditions such as pain, Alzheimer's disease, migraine, and obesity. A major milestone for the company was its acquisition by Pfizer in mid-2006 for approximately $500 million. This acquisition was a strategic move by Pfizer to bolster its neuroscience pipeline and expand its presence in biologics. At the time of the acquisition, Rinat had several promising candidates in its pipeline.

Rinat's product development yielded several notable antibody-based drugs. Tanezumab (RN624) was developed for pain treatment, specifically in osteoarthritis, by inhibiting nerve growth factor (NGF). Another significant candidate was Ponezumab (RN1219), a humanized monoclonal antibody for Alzheimer's disease that aimed to reduce the buildup of amyloid plaque deposits in the brain. The pipeline also included Fremanezumab (RN307) for migraine prevention and Bococizumab (RN316) to reduce LDL cholesterol, among others targeting conditions like type 2 diabetes and ovarian cancer. Following the acquisition, Rinat began operating as an independent biotechnology unit within Pfizer's global research and development group, continuing its work from South San Francisco.
