Bayer says won't get results from Stivarga trial in bowel cancer

[March 05, 2015]  FRANKFURT (Reuters) - German drugmaker Bayer said it would not get any relevant results from a Phase III trial of regorafenib, a drug also known as Stivarga, for the treatment of colorectal cancer, because it failed to recruit a sufficient number of participants.

The study in the third and last phase required for regulatory approval was designed to evaluate regorafenib as an additional treatment of colorectal cancer following surgical removal of liver metastases with curative intent.

"As a result of slow patient accrual, the study will be closed to further enrolment before the study endpoints can be assessed. Importantly, there were no new safety signals from the study," Bayer said in a statement.

Bayer will continue to evaluate regorafenib in a number of tumor types, including colorectal cancer, it added.
