Pfizer’s failure provides clarity for Arqule
Tuesday, August 24th, 2010Yesterday Pfizer (PFE) announced that Sutent failed to prolong survival of lung cancer patients when given in combination with Tarceva. The drug led to an increase in progression free survival (PFS), which was the secondary endpoint of the study. The results are not published and there are several open questions such as the extent of PFS improvement, benefit across different subtypes and use of Sutent in patients from the placebo cohort after progressing on Tarceva. Nevertheless, chances to see Sutent+Tarceva as a standard of care for 2nd/3rd line NSCLC are slim.
Pfizer’s failure provided some clarity for Arqule (ARQL) and its partner Daiichi Sankyo, who plan to initiate a phase III study for ARQ-197 in combination with Tarceva. The indication Arqule is pursuing is very similar to that pursued by Pfizer, so had the Sutent trial been successful, it would have adversely affect ARQ-197’s prospects in general and potentially the required clinical route.
