clinical trialGenentech, a member of the Roche Group, has today announced that the Phase III GOYA study evaluating Gazyva (obinutuzumab) plus CHOP chemotherapy (G-CHOP) in people with previously untreated diffuse large B-cell lymphoma (DLBCL) did not meet its primary endpoint of significantly reducing the risk of disease worsening or death (progression-free survival; PFS) compared with Rituxan (rituximab) plus CHOP chemotherapy (R-CHOP).

Adverse events with Gazyva and Rituxan were consistent with those seen in previous clinical trials when each was combined with various chemotherapies. Data from the GOYA study will be presented at an upcoming medical meeting.

“Two previous studies showed Gazyva helped people with previously untreated follicular lymphoma or chronic lymphocytic leukemia live longer without their disease worsening compared with Rituxan, when each was combined with chemotherapy. We were hopeful we could show a similar result for people with diffuse large B-cell lymphoma and once again improve on the standard of care,” said Sandra Horning, MD, Chief Medical Officer and Head of Global Product Development. “We will continue to analyse the GOYA data to better understand the results, and to study other investigational treatments in this disease with the goal of further helping these patients.”

About Gazyva: Gazyva is an engineered monoclonal antibody designed to attach to CD20, a protein found on certain types of B-cells. It is thought to work by attacking targeted cells both directly and together with the body’s immune system. Gazyva was discovered by Roche Glycart AG, a wholly owned, independent research unit of Roche. In the United States, Gazyva is part of a collaboration between Genentech and Biogen.
