History and Overview:
In July 2019, Pfizer acquired Array BioPharma Inc., a Boulder-based biopharmaceutical company focused on the discovery, development and commercialization of targeted small molecule drugs to treat patients afflicted with cancer and other high-burden diseases. Following the acquisition of Array, Pfizer Boulder R&D joined the company’s vast network of research units, helping to enhance Pfizer’s Oncology franchise.

Pfizer Boulder’s expertise is in small molecule drug discovery, and the team has a successful track record in targeting the very important RAS/RAF/MEK/ERK signaling pathway, which is central to many types of cancer. Over the past two decades, the Boulder team has built an outstanding reputation in drug discovery and development, including filing 27 investigational new drug applications with the U.S. Food and Drug Administration (FDA).

When the site became part of Pfizer, it brought a compelling existing portfolio, including the combination of BRAFTOVI® and MEKTOVI®. In April 2020, the FDA also granted approval of BRAFTOVI in combination with cetuximab for an additional indication. Additionally, Pfizer Boulder scientists are proud to have played a significant role in the discovery, development, or both, of several royalty-generating, out-licensed medicines, including a number of novel tyrosine kinase inhibitors that address significant unmet needs across many types of cancer.

Currently, the Boulder pipeline has a promising range of potentially first- and best-in-class programs that may advance the next wave of innovative cancer treatments, including several next-generation, targeted molecules that may have the potential to penetrate the blood brain barrier.
