BOSTON and WILMINGTON, Del. – April 16, 2023 – MorphoSys U.S. Inc., a fully owned subsidiary of MorphoSys AG (FSE: MOR; NASDAQ: MOR), and Incyte (Nasdaq: INCY) today announced final five-year follow-up data from the Phase 2 L-MIND study showing that Monjuvi® (tafasitamab-cxix) plus lenalidomide followed by Monjuvi monotherapy provided prolonged, durable responses in adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL). These data were featured as a late-breaking oral presentation (Abstract # CT022) at the American Association for Cancer Research (AACR) Annual Meeting 2023 in Orlando, Florida.


“Five-year data demonstrating durability of response is meaningful for oncologists as they consider the most appropriate treatment option for a patient,” said Johannes Duell, M.D., University Hospital Würzburg Medical Clinic and Polyclinic. “The prolonged and durable responses seen at five years among relapsed or refractory DLBCL patients in the L-MIND study show that the Monjuvi treatment regimen may have curative potential, which I look forward to seeing explored in future studies.”


At the data cut-off (Nov. 14, 2022) for the full analysis set (80 patients), the overall response rate (ORR) was 57.5% (95% CI = 45.9, 68.5), and a complete response (CR) was observed in 41.2% of patients (95% CI = 30.4, 51.6; n = 33). A partial response (PR) was observed in 16.2% of patients (95% CI = 8.9, 26.2; n =13). Additional results include:

  • Median duration of response was not reached after a median follow up of 44.0 months (95% CI = 29.9, 57.0).
  • The median overall survival was 33.5 months (95% CI = 18.3, NR) and median progression-free survival was 11.6 months (95% CI = 5.7, 45.7).
  • Of the 21 patients with >60 months of follow-up, 14 had received one prior line of therapy (pLoT), and seven patients had received ≥2 pLoT.
  • Patients with one pLoT (n = 40) had a higher ORR of 67.5% (CR = 52.5% and PR = 15%) compared to 47.5% of patients with two or more pLoT (n = 40; CR = 30% and PR = 17.5%)


No new safety signals were identified. The majority of adverse events (AEs) were grade 1 or grade 2 during both combination and monotherapy treatment. Patients experienced a lower frequency of all-grade and grade 3 or higher adverse events during monotherapy. The most common adverse events with combination therapy were neutropenia (incidence per person per year, all-grade/grade ≥3: 3.79/2.09) and thrombocytopenia (1.52/0.52), which declined after patients switched to monotherapy (all-grade/grade ≥3: 1.09/0.70 and 0.17/0.06, respectively, in the first two years of monotherapy). Neutropenia and diarrhea were the most common adverse events in the first two years of monotherapy.


“The totality of the long-term L-MIND data presented at AACR further reinforce our confidence that the Monjuvi plus lenalidomide combination remains the in-practice, outpatient, targeted immunotherapy option that can provide sustained remissions for patients with relapsed or refractory DLBCL who are not eligible for autologous stem cell transplant,” said Tim Demuth, M.D., Ph.D., Chief Research and Development Officer, MorphoSys. “The durable responses and consistent safety profile observed in the five-year analysis are encouraging and further support the use of the Monjuvi regimen as a potentially curative option for appropriate patients.”


“The new five-year L-MIND data build on prior analyses that detail the potential for Monjuvi plus lenalidomide to provide long-term, meaningful responses for certain patients with relapsed or refractory DLBCL, a historically difficult-to-treat form of the disease,” said Steven Stein, M.D., Chief Medical Officer, Incyte. “We look forward to continuing to explore the potential of Monjuvi to help patients with newly diagnosed DLBCL, as well as other CD19-expressing lymphomas.”


In July 2020, the U.S. Food and Drug Administration (FDA) approved Monjuvi in combination with lenalidomide for the treatment of adult patients with relapsed or refractory DLBCL not otherwise specified, including DLBCL arising from low grade lymphoma, and who are not eligible for ASCT. This indication is approved under accelerated approval based on ORR. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s). The U.S. approval is based on an efficacy subgroup of 71 patients confirmed by central lab. The FDA decision represented the first approval of a second-line treatment for adult patients with DLBCL who progressed during or after first-line therapy. Monjuvi, in combination with lenalidomide, was granted accelerated approval based on the one-year primary analysis of the L-MIND study. The data for the five-year analysis of the L-MIND study have not yet been submitted to, or reviewed by, the FDA.
