gw786034 in subjects with locally recurrent or metastatic clear cell renal cell carcinoma

Conditions: Carcinoma, Renal Cell

Summary: phase ii, multi-center, two-stage study utilising a randomised discontinuation design to evaluate the safety and efficacy of gw786034 (pazopanib) in adult subjects with locally recurrent or metastatic clear-cell renal cell carcinoma (rcc). after the interim analysis, the design was changed to an open label, single arm study with all subjects receiving pazopanib.
