Pfizer Inc (NASDAQ: PFE) is a top 5 biopharmaceutical company that develops and produces medication and vaccines for life-threatening diseases in immunology, oncology, cardiology, endocrinology, and neurology. Pfizer’s Product X inhibits a novel target in the treatment of a resistant type of prostate cancer. Abingworth and Pfizer entered into a clinical co-development funding agreement worth up to $200M. The capital will be used to support Pfizer’s Phase 3 study, investigating Product X in combination with another drug for patients with who have failed a certain prior treatment. Substantial unmet need exists in this setting of prostate cancer as many patients do not respond adequately to existing therapies or develop resistance to them. A Joint Steering Committee with representatives from Abingworth and Launch Therapeutics, Abingworth’s wholly owned clinical development portfolio company, has been established to oversee the Phase 3 development program.
