Roche has announced that its experimental leukemia drug GA101, or obinutuzumab, used in combination with chemotherapy, was better than Rituxan at helping people with chronic lymphocytic leukemia live longer without their disease worsening, according to the results from the second phase of the clinical trial. Both drugs were tested and compared in combination with chlorambucil.

GA101 is the first glycoengineered, type II anti-CD20 monoclonal antibody (mAb) that has been designed for increased antibody-dependent cellular cytotoxicity (ADCC) and Direct CellDeath.1 This agent is being investigated in collaboration with Biogen Idec.
Swiss pharmaceutical company Roche has announced that its early Phase III trial of Leukemia drug obinutuzumab (GA101) demonstrated significantly improved progression-free survival in people with chronic lymphocytic leukemia (CLL).
The positive results yield from stage 1 of a three-arm study called CLL11, designed to investigate the efficacy and safety profile of obinutuzumab (GA101) plus chlorambucil, a chemotherapy, compared with chlorambucil alone in people with previously untreated chronic lymphocytic leukemia (CLL).
This phase of the study met its primary endpoint and an improvement in progression-free survival was achieved; obinutuzumab plus chlorambucil significantly reduced the risk of disease worsening or death compared to chlorambucil alone.
Roche chief medical officer and global product development head Hal Barron said; “the improvement in progression-free survival seen with GA101 is encouraging for people with CLL, a chronic illness of older people for which new treatment options are needed.”
“GA101 demonstrates our ongoing commitment to the research and development of new medicines for this disease.”
Obinutuzumab is Roche’s most advanced drug in development for the treatment of hematological malignancies.
It has been specifically designed as the first glycoengineered, type 2 anti-CD20 monoclonal antibody in development for B cell malignancies.
Afutuzumab is a monoclonal antibody being developed by Hoffmann-La Roche Inc. for the treatment of lymphoma.[1] It acts as an immunomodulator.[2][3] It was renamed obinutuzumab in 2009.[4]
