The US Food and Drug Administration (FDA) has granted priority review to a supplemental biologics license application (sBLA) for obinutuzumab (Gazyva®).
With this sBLA, Genentech is seeking approval for obinutuzumab to be used, first in combination with chemotherapy and then alone as maintenance, in patients with previously untreated follicular lymphoma (FL).
The FDA grants priority review to applications for products that may provide significant improvements in the treatment, diagnosis, or prevention of serious conditions.
The agency’s goal is to take action on a priority review application within 6 months of receiving it, rather than the standard 10 months.
The FDA plans to make a decision on the sBLA for obinutuzumab by December 23, 2017.
The sBLA is supported by results of the GALLIUM study, which were presented at the 2016 ASH Annual Meeting.
About obinutuzumab
Obinutuzumab is a glycoengineered, humanized, monoclonal antibody that selectively binds to the extracellular domain of the CD20 antigen on B cells.
The drug is FDA-approved for use in combination with chlorambucil to treat patients with previously untreated chronic lymphocytic leukemia.
Obinutuzumab is also approved to treat FL patients who relapse after, or are refractory to, a rituximab-containing regimen. In these patients, obinutuzumab is given first in combination with bendamustine and then alone as maintenance.
The full prescribing information for obinutuzumab is available at http://www.Gazyva.com.
About the GALLIUM study
GALLIUM enrolled 1401 patients with previously untreated, indolent non-Hodgkin lymphoma, including 1202 with FL.
Half of the FL patients (n=601) were randomized to receive obinutuzumab plus chemotherapy (followed by obinutuzumab maintenance for up to 2 years), and half were randomized to rituximab plus chemotherapy (followed by rituximab maintenance for up to 2 years).
The different chemotherapies used were CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone), CVP (cyclophosphamide, vincristine, and prednisolone), and bendamustine.
Patients who received obinutuzumab had significantly better progression-free survival than patients who received rituximab. The 3-year progression-free survival rate was 73.3% in the rituximab arm and 80% in the obinutuzumab arm (hazard ratio [HR]=0.66, P=0.0012).
There was no significant difference between the treatment arms with regard to overall survival. The 3-year overall survival was 92.1% in the rituximab arm and 94% in the obinutuzumab arm (HR=0.75, P=0.21).
The overall incidence of adverse events (AEs) was 98.3% in the rituximab arm and 99.5% in the obinutuzumab arm. The incidence of serious AEs was 39.9% and 46.1%, respectively.
The incidence of grade 3 or higher AEs was higher among patients who received obinutuzumab.
Grade 3 or higher AEs occurring in at least 5% of patients in either arm (rituximab and obinutuzumab, respectively) included neutropenia (67.8% and 74.6%), leukopenia (37.9% and 43.9%), febrile neutropenia (4.9% and 6.9%), infections and infestations (3.7% and 6.7%), and thrombocytopenia (2.7% and 6.1%).
