PF-3512676 dosing was stopped 21 June 2007 when Pfizer decided to stop the administration of PF-3512676 in all trials which combined PF-3512676 with cytotoxic chemotherapy. The decision was made subsequent to DSMC recommendation to close two phase III randomized trials in non-small cell lung cancer which also combined PF-3512676 with cytotoxic chemotherapy, citing lack of efficacy concerns as the primary reason with safety issues (sepsis, thrombocytopenia) also contributing to the decision. Subjects were allowed to complete standard of care treatment and protocol follow-up. Data collection was completed on 31 January 2008.
