The findings, including data from patients treated with the targeted immunotherapy for 5 years or more, will be presented during the Tenth Annual Meeting of the Society of Hematologic Oncology (SOHO 2022)
MorphoSys U.S. Inc., a fully owned subsidiary of MorphoSys AG (FSE: MOR; NASDAQ: MOR), today announced data from the ongoing L-MIND study showing that Monjuvi® (tafasitamab-cxix) plus lenalidomide followed by Monjuvi monotherapy provided long-term efficacy in patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) treated for at least 2 years, including six patients on treatment for 5 years or more. Additionally, the frequency of adverse events declined after patients transitioned from combination therapy to monotherapy. The data will be presented during a poster session at the Tenth Annual Meeting of the Society of Hematologic Oncology (SOHO 2022) in Houston, Texas.
“The body of data presented at SOHO shows the long-term duration of response to tafasitamab in some patients with relapsed or refractory diffuse large B-cell lymphoma not eligible for autologous stem-cell transplant,” said Malte Peters, M.D., MorphoSys Chief Research and Development Officer. “These long-term follow-up results for L-MIND reaffirm our belief that tafasitamab plus lenalidomide remains the in-practice, outpatient targeted immunotherapy of choice for this group of patients.”
At data cutoff (February 15, 2022), 27 of 80 patients (34%) had undergone treatment for at least 2 years, with a median duration of treatment of 4.3 years. Of those 27, 23 patients were alive at data cutoff, and 13 remained on treatment, including six who were on treatment for at least 5 years.
A complete response was observed in 23 of the 27 patients, including four who were refractory to their primary therapy. A partial response was seen in four patients, two of whom were still on treatment at data cutoff.
The majority of adverse events were grade 1 or 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: 3.87/1.91) and diarrhea (1.04/0.04), which declined after patients switched to monotherapy (all-grade/Grade ≥3: 0.87/0.45 and 0.32/0.00, respectively, in the first year of monotherapy). Neutropenia and diarrhea remained the most common adverse events in the first two years of monotherapy.
“The new long-term follow-up results from L-MIND at SOHO 2022 highlight the potential of tafasitamab in providing long-term efficacy in patients with relapsed or refractory diffuse large B-cell lymphoma,” said Johannes Duell, M.D., University Hospital Wuerzburg Medical Clinic and Polyclinic. “The fact that six of the 27 patients who responded received treatment for 5 or more years – with another seven patients nearing the 5-year mark – points to the durable response induced by tafasitamab. This response durability represents the type of data that offers oncologists confidence when recommending therapies to their patients.”

About Monjuvi® (tafasitamab-cxix)
Tafasitamab is a humanized Fc-modified CD19 targeting immunotherapy. In 2010, MorphoSys licensed exclusive worldwide rights to develop and commercialize tafasitamab from Xencor, Inc. Tafasitamab incorporates an XmAb® engineered Fc domain, which mediates B-cell lysis through apoptosis and immune effector mechanism including Antibody-Dependent Cell-Mediated Cytotoxicity (ADCC) and Antibody-Dependent Cellular Phagocytosis (ADCP).
In the United States, Monjuvi® (tafasitamab-cxix) is approved by the U.S. Food and Drug Administration 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 autologous stem cell transplant (ASCT). This indication is approved under accelerated approval based on overall response rate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).
In Europe, Minjuvi® (tafasitamab) received conditional marketing authorization in combination with lenalidomide, followed by Minjuvi monotherapy, for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who are not eligible for autologous stem cell transplant (ASCT).
Tafasitamab is being clinically investigated as a therapeutic option in B-cell malignancies in several ongoing combination trials.
