SUGEN
SUGEN (Sugen) was a drug discovery company focused on development of protein kinase inhibitors. It was founded in 1991, and shut down in 2003, after pioneering protein kinases as therapeutic targets and developing the successful cancer therapy sunitinib (Sutent).
Early history and focus
Sugen was founded in 1991 in
Research and drug development
Sugen went public in October 1994 (NASDAQ: SUGN).) was approved for canine tumors.
Sugen was funded through a number of collaborative research programs with companies including ASTA Medica (pan-Her and Raf programs), Allergan (ophthalmic angiogenesis inhibition), Zeneca (EGFR and cancer), and Amgen all of which took equity stakes in the company,[5] and Taiho (cancer).[6] Conversely, Sugen was an investor in and collaborator with Selectide for the development of peptide kinase inhibitors.[7]
Mergers
Sugen was acquired by Pharmacia & Upjohn in 1999 in a stock swap valued at $650 million.[8] In December 1999, Pharmacia & Upjohn merged with Monsanto.[9] The company was renamed Pharmacia in 2002.[10] Pharmacia was then acquired by Pfizer in April 2003.[11]
Shutdown and legacy
The Pfizer-Pharmacia merger lead to major cuts in research activities, including the shut down of Sugen over the course of 2003, with the loss of approximately 350 employees.[1] Pfizer continued the phase 3 trials and development of SU11248, now known as Sutent (sunitinib),[4] leading to Food and Drug Administration approval in January 2006 for treatment of RCC and GIST tumors. Other programs also transferred to Pfizer, including a follow-on compound to SU11248, known as SU14813, and programs on Met and PAK kinases. Work started at Sugen also contributed to the development of the ALK inhibitor crizotinib (Xalkori), FDA-approved for NSCLC in 2011.[12][13] Sugen also generated extensive basic research on kinase biology, including the publication of almost 300 research papers,[1] the definition of the human kinome, and the discovery of over 140 human kinase genes. Sugen alumni have gone on to major positions[14] in other pharmaceutical and kinase-focused companies. In 2010, Sutent surpassed $1bn in annual revenues for Pfizer.[15][16]
