Genmab Announces U.S. FDA Approval of Arzerra (ofatumumab) in Combination with Fludarabine and Cyclophosphamide for Relapsed CLL

Copenhagen, Denmark; August 31, 2016 — Genmab A/S (Nasdaq Copenhagen: GEN) announced today that the U.S. Food and Drug Administration (FDA) has approved a supplemental Biologics License Application (sBLA) for the use of ofatumumab (Arzerra®) in combination with fludarabine and cyclophosphamide (FC) for the treatment of patients with relapsed chronic lymphocytic leukemia (CLL). The application, which received Priority Review in May 2016, was submitted to the FDA by Novartis under the ofatumumab collaboration between Novartis and Genmab.

Approval for this indication by the FDA is based on results from the Phase III COMPLEMENT 2 study that evaluated ofatumumab in combination with FC versus FC alone in patients with relapsed CLL. Top-line results from COMPLEMENT 2 were reported in April 2015.

"This is the fourth CLL indication approved in the U.S. for Arzerra, and we are pleased to see the availability of this treatment expand to a wider number of patients," said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab.

About CLL

CLL is the most commonly diagnosed adult leukemia in Western countries, and accounts for approximately 1 in 4 cases of leukemia.1 Most CLL patients experience disease progression despite initial response to therapy and may require additional treatment.2

About COMPLEMENT 2

COMPLEMENT 2 (NCT00824265) is an open-label, two-arm, randomized, Phase III study, which included 365 patients in 18 countries with relapsed CLL. Patients in the study were randomized 1:1 to treatment with up to six cycles of ofatumumab in combination with fludarabine and cyclophosphamide (FC) or up to six cycles with fludarabine and cyclophosphamide alone. The primary endpoint of the study was progression free survival (PFS), which was assessed by an Independent Review Committee (IRC) according to the International Workshop for Chronic Lymphocytic Leukaemia (iwCLL) updated 2008 National Cancer Institute-sponsored Working Group (NCIWG) guidelines.3 The study met the primary endpoint with a median progression free survival in patients receiving ofatumumab in combination with FC of 28.9 months, compared to 18.8 months in patients receiving FC alone (HR =0.67, p=0.0032). Secondary endpoints included overall response rate, overall survival, patient reported outcomes, time to response, duration of response, time to progression, time to next therapy, safety assessments and quality of life. The safety profile observed in this study was consistent with other trials of ofatumumab and no new safety signals were observed.

About Ofatumumab (Arzerra)

Ofatumumab is a human monoclonal antibody that is designed to target the CD20 molecule found on the surface of chronic lymphocytic leukemia (CLL) cells and normal B lymphocytes. In the United States, Arzerra is approved for use in combination with chlorambucil for the treatment of previously untreated patients with CLL for whom fludarabine-based therapy is considered inappropriate and for extended treatment of patients who are in complete or partial response after at least two lines of therapy for recurrent or progressive CLL. In the European Union, Arzerra is approved for use in combination with chlorambucil or bendamustine for the treatment of patients with CLL who have not received prior therapy and who are not eligible for fludarabine-based therapy. In more than 50 countries worldwide, Arzerra is also indicated as monotherapy for the treatment of patients with CLL who are refractory after prior treatment with fludarabine and alemtuzumab.
