The European Medicine Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended that obinutuzumab (Gazyvaro), an anti-CD20 monoclonal antibody, be approved for use in patients with follicular lymphoma (FL).
The recommended indication is for obinutuzumab to be given first in combination with bendamustine and then as maintenance therapy in FL patients who did not respond to, progressed during, or progressed up to 6 months after treatment with rituximab or a rituximab-containing regimen.
Based on the CHMP’s recommendation, a final decision regarding the approval of obinutuzumab in FL is expected from the European Commission in the coming months.
Obinutuzumab is already approved in the European Union for use in combination with chlorambucil to treat patients with previously untreated chronic lymphocytic leukemia and comorbidities that make them unsuitable for full-dose fludarabine-based therapy.
Obinutuzumab is being developed by Roche.
GADOLIN trial
The CHMP’s recommendation to approve obinutuzumab in FL is based on results from the phase 3 GADOLIN trial. The study included 413 patients with rituximab-refractory non-Hodgkin lymphoma, including 321 patients with FL, 46 with marginal zone lymphoma, and 28 with small lymphocytic lymphoma.
The patients were randomized to receive bendamustine alone (control arm) or a combination of bendamustine and obinutuzumab followed by obinutuzumab maintenance (every 2 months for 2 years or until progression).
The primary endpoint of the study was progression-free survival (PFS), as assessed by an independent review committee (IRC). The secondary endpoints were PFS assessed by investigator review, best overall response, complete response (CR), partial response (PR), duration of response, overall survival, and safety profile.
Among patients with FL, the obinutuzumab regimen improved PFS compared to bendamustine alone, as assessed by IRC (hazard ratio [HR]=0.48, P<0.0001). The median PFS was not reached in patients receiving the obinutuzumab regimen but was 13.8 months in those receiving bendamustine alone.
Investigator-assessed PFS was consistent with IRC-assessed PFS. Investigators said the median PFS with the obinutuzumab regimen was more than double that with bendamustine alone—29.2 months vs 13.7 months (HR=0.48, P<0.0001).
The best overall response for patients receiving the obinutuzumab regimen was 78.7% (15.5% CR, 63.2% PR), compared to 74.7% for those receiving bendamustine alone (18.7% CR, 56% PR), as assessed by the IRC.
The median duration of response was not reached for patients receiving the obinutuzumab regimen and was 11.6 months for those receiving bendamustine alone.
The median overall survival has not yet been reached in either study arm.
The most common grade 3/4 adverse events observed in patients receiving the obinutuzumab regimen were neutropenia (33%), infusion reactions (11%), and thrombocytopenia (10%).
The most common adverse events of any grade were infusion reactions (69%), neutropenia (35%), nausea (54%), fatigue (39%), cough (26%), diarrhea (27%), constipation (19%), fever (18%), thrombocytopenia (15%), vomiting (22%), upper respiratory tract infection (13%), decreased appetite (18%), joint or muscle pain (12%), sinusitis (12%), anemia (12%), general weakness (11%), and urinary tract infection (10%).
