Genmab Announces Topline Results in Phase III study of Arzerra® in Indolent Non-Hodgkin’s Lymphoma
Topline results from Phase III study in iNHL did not meet primary endpoint of improved progression-free survival
Genmab A/S (Nasdaq Copenhagen: GEN) announced today that topline results from the Phase III study of Arzerra® (ofatumumab) plus bendamustine did not meet the primary endpoint of improved progression-free survival (PFS) in patients with indolent B-cell non-Hodgkin’s lymphoma (iNHL) who were unresponsive to rituximab or a rituximab-containing regimen, compared to those given bendamustine alone. The safety profile observed in this study was consistent with that observed in other trials of ofatumumab and no new safety signals were observed.
“We are disappointed that the ofatumumab treatment regimen did not meet the primary endpoint in this trial. The completion of this Phase III study, which began in 2010, would not have been possible without the generous participation of the patients and their families, and we are most grateful for this. The full data will be submitted for publication at a future medical conference and we hope that these will provide a better understanding of this result,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab.
The results from this Phase III study do not impact any other ongoing studies with ofatumumab.
About the study (COMPLEMENT A+B)
The study is an open-label, two-arm, randomized, Phase III study that included 346 patients with indolent B-cell non-Hodgkin’s lymphoma who were unresponsive to rituximab or a rituximab-containing regimen. Patients in the study were randomized 1:1 to treatment with up to eight cycles of bendamustine given in combination with 12 doses of ofatumumab (1,000 mg) or up to eight cycles with bendamustine alone. The primary endpoint of the study was PFS.
Ofatumumab is not approved for the treatment of indolent non-Hodgkin’s Lymphoma.
