OSI-774 OSI Pharmaceuticals.
OSI-774 (formerly CP-358774), a quinazoline derivative, is an orally active epidermal growth factor receptor (EGFR) inhibitor which was originally under joint development by Pfizer and OSI Pharmaceuticals (formerly Oncogene Science) for the potential treatment of cancer (eg, ovarian, non-small cell lung cancer (NSCLC) and head and neck). It is being evaluated in phase II trials [304305], [372201]. On 8 January 2001, OSI announced that it had signed an agreement with Roche and Genentech for the global co-development and marketing of OSI-774. The agreement with Genentech covers the United States, that with Roche the rest of the world [395371], [395526]. In June 2000, OSI gained all development and marketing rights for OSI-774 following Pfizer's merger with Warner-Lambert [371439]. In September 2000, Pfizer transferred the IND dossierfor OSI-774 to OSI ahead of the timeline agreed in the June 2000 development and marketing rights agreement [383786]. The phase II trials will assess OSI-774 both as a single agent and in combination with existing chemotherapy regimens [347783]. Phase III trials are expected to be initiated in 2001 [347783]. In October 2000, Lehman Brothers predicted that OSI-774 would move into pivotal trials in thefirst half of 2001 and that the drug would be launched in 2003. The analysts also estimated worldwide sales of US $66 million, $285 million and $461 million in 2003, 2004 and 2005, respectively, and peak sales in excess of US $500 million [395189].
