Incyte  announces positive topline results from the pivotal Phase 3 inMIND trial evaluating the efficacy and safety of tafasitamab (Monjuvi^®), a humanized Fc-modified cytolytic CD19 targeting monoclonal antibody, or placebo in combination with lenalidomide and rituximab compared to lenalidomide and rituximab alone in patients with relapsed or refractory follicular lymphoma (FL).

The trial met its primary endpoint of progression free survival (PFS) by investigator assessment in FL. It also met key secondary endpoints of PFS in the overall population by investigator assessment as well as the positron-emission tomography-complete response rate in the FDG-avid FL population. In addition, the secondary endpoint of PFS results by blinded independent review are consistent with investigator based PFS results. No new safety signals with tafasitamab were observed.

“While many patients with follicular lymphoma initially benefit from first-line treatment, relapse of the disease is common, underscoring the need for additional therapies,” said Steven Stein, M.D., Chief Medical Officer, Incyte. “These results demonstrate the potential of tafasitamab added to the standard of care to be a meaningful new treatment option for patients with FL whose disease has progressed after at least one prior therapy.”

FL is the most common indolent, or slow growing, form of B-cell non-Hodgkin lymphoma (NHL) and accounts for approximately 13-26% of overall NHL cases.^1,2,3,4,5 There are limited treatment options for the more than 17,000 new cases of relapsed or refractory FL treated every year in the United States, Europe and Japan.⁶

Based on these positive results, Incyte expects to file a supplemental Biologics License Application for tafasitamab for the treatment of patients with FL who have failed at least one prior systemic anti-CD20 immunotherapy or chemo-immunotherapy by the end of the year.

The full inMIND data will also be submitted for presentation at an upcoming scientific meeting.

Tafasitamab was approved in combination with lenalidomide by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) in 2020 and 2021 respectively, for adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) not otherwise specified including DLBCL arising from low-grade lymphoma, and who are not eligible for autologous stem cell transplant. Tafasitamab is marketed as Monjuvi^® (tafasitamab-cxix) in the United States and Minjuvi^® (tafasitamab) in Europe and Canada.
