Roche announced updated data from the pivotal CLL11 study confirming that Gazyva®/Gazyvaro® (obinutuzumab) plus chlorambucil reduced the risk of disease worsening or death by more than half compared to MabThera®/Rituxan® (rituximab) plus chlorambucil (progression-free survival, PFS; HR=0.46, median PFS 28.7 months versus 15.7 months; p<0.0001). New results to be presented at the American Society of Hematology (ASH) Annual Meeting from a secondary endpoint that measured time to next treatment (TTNT) showed that, after completing the set six-month Gazyva/Gazyvaro regimen, people remained treatment-free for nearly four years on average before needing the next treatment for their cancer (TTNT; 51.1 months, including the six month initial treatment period). No unexpected safety signals were observed with Gazyva/Gazyvaro.
In the GREEN safety study, data from a subgroup analysis showed there were no unexpected safety signals when Gazyva/Gazyvaro was combined with bendamustine. In addition, nearly 80 percent of people responded to treatment with Gazyva/Gazyvaro plus bendamustine (overall response, ORR), and a third of people (32.3 percent) achieved a complete response (CR). A substantial number of people were also minimal residual disease (MRD) negative when measured in the bone marrow or blood (28 percent and 59 percent, respectively), which means no cancer can be detected using a specific test. Overall response rate and MRD were secondary endpoints of the study.
