The European Commission (EC) has granted marketing authorization for ofatumumab (Arzerra®) to be used in combination with fludarabine and cyclophosphamide (FC) in the treatment of adults with relapsed chronic lymphocytic leukemia (CLL).
Ofatumumab is a monoclonal antibody designed to target CD20. The drug is marketed under a collaboration agreement between Genmab and Novartis.
The EC previously authorized the use of ofatumumab as a single agent to treat CLL patients who are refractory to fludarabine and alemtuzumab.
The agency also authorized the use of ofatumumab in combination with chlorambucil or bendamustine in CLL patients who have not received prior therapy and are not eligible for fludarabine-based therapy.
The EC’s decision to approve the use of ofatumumab in combination with FC was based on results from the phase 3 COMPLEMENT 2 study, which were published in Leukemia & Lymphoma in October.
The trial enrolled 365 patients with relapsed CLL. The patients were randomized 1:1 to receive up to 6 cycles of ofatumumab in combination with FC or up to 6 cycles of FC alone.
The primary endpoint was progression-free survival, as assessed by an independent review committee.
The median progression-free survival was 28.9 months for patients receiving ofatumumab plus FC, compared to 18.8 months for patients receiving FC only (hazard ratio=0.67, P=0.0032).
The incidence of grade 3 or higher adverse events was 74% in the ofatumumab-plus-FC arm and 69% in the FC-only arm. Neutropenia was the most common of these events, occurring in 49% and 36% of patients, respectively.
