Sanofi Cancer Drug Didn't Meet Endpoints

PARIS ( TheStreet) -- Sanofi-Aventis ( SNY) shares fell almost 5% Friday after its cancer drug iniparib didn't meet primary endpoints of overall survival and progression-free survival for breast cancer patients.

The Phase III clinical trial evaluated in patients with metastatic triple-negative breast cancer. The study enrolled 519 women with the cancer from 109 sites in the United States. Patients were randomized to receive a standard chemotherapy regimen (gemcitabine and carboplatin) with iniparib to one without the drug.

Sanofi-Aventis, the French drugmaker, said there wasn't a significant difference between the two regimens.
