In February 2002, Pharmacia, the then-parent of Sugen, prematurely ended phase III clinical trials of semaxinib in the treatment of advanced colorectal cancer due to discouraging results.[2] Other studies, at earlier phases, have since been conducted.[3][4] However, due to the prospect of next-generation tyrosine kinase inhibitors and the inefficacy of semaxanib in clinic trials, further development of the drug has been discontinued.[5] A related compound, SU11248 (sunitinib), was further developed by Sugen and subsequently by Pfizer, and received FDA approval for treatment of renal carcinoma in January 2006.[6]
When combined with chronic exposure to hypoxia, SU5416 induces severe pulmonary hypertension in mice and rats. This property has been exploited to develop a series of useful, though controversial, rodent models of pulmonary arterial hypertension, the first and best characterized being the Sugen/Hypoxia (SuHx) mouse model.[7][8]
