Data Evaluating Tafasitamab with and without Lenalidomide in Combination with R-CHOP in Patients with DLBCL Presented at ASH 2020

Rhea-AI Summary

Incyte and MorphoSys AG presented preliminary data from the firstMIND study at the 62nd ASH Annual Meeting, focusing on tafasitamab and lenalidomide combined with R-CHOP for newly diagnosed DLBCL patients. Results showed an acceptable tolerability profile, with serious neutropenia and thrombocytopenia more frequent in the combination arm. Objective response rates were high, with 91.1% of patients responding after three cycles. A Phase 3 trial, frontMIND, will evaluate this combination as first-line treatment. Long-term analyses from the L-MIND study also indicated durable responses with no unexpected safety signals.

Positive

• 91.1% objective response rate observed in preliminary results.
• Initiation of frontMIND Phase 3 trial planned for 2021.
• Long-term L-MIND data showed durable treatment responses after ≥2 years.

Negative

• Serious or severe neutropenia and thrombocytopenia more frequent in combination therapy group.

WILMINGTON, Del. & PLANEGG/MUNICH, Germany--(BUSINESS WIRE)--Incyte (Nasdaq:INCY) and MorphoSys AG (FSE: MOR; Prime Standard Segment; MDAX & TecDAX; NASDAQ:MOR) announce that preliminary data from firstMIND, the ongoing Phase 1b, open-label, randomized study on the safety and efficacy of tafasitamab or tafasitamab plus lenalidomide in addition to R-CHOP for patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL) were presented today during the 62^nd American Society of Hematology Annual Meeting & Exposition (ASH). Additionally, a long-term subgroup analysis of the L-MIND study investigating tafasitamab combined with lenalidomide in patients with relapsed or refractory DLBCL was also presented at ASH.

The preliminary results of firstMIND indicate that tafasitamab plus lenalidomide in addition to R-CHOP shows an acceptable tolerability profile. Toxicities appear to be similar to what is expected with R-CHOP alone or in combination with lenalidomide. Serious or severe neutropenia and thrombocytopenia events (grade 3 or higher) were more frequent in the tafasitamab plus lenalidomide arm. The incidence of febrile neutropenia was comparable between both arms and the average relative dose intensity of R-CHOP was maintained in both arms. Interim response assessments after three cycles were available for 45 patients. In both arms combined, 41/45 (91.1%) of patients had an objective response as per Lugano 2014¹.

The preliminary data from this ongoing study in first-line DLBCL warrant further investigation. To that end, MorphoSys and Incyte plan to initiate frontMIND, a Phase 3 trial evaluating tafasitamab plus lenalidomide in combination with R-CHOP compared to R-CHOP alone as first-line treatment for patients with newly diagnosed DLBCL.

“The initial results of the firstMIND study, shared today at ASH, as well as the long-term analyses from L-MIND, underscore the potential of tafasitamab as a combination therapeutic for patients with DLBCL, where there remains a significant unmet need. Along with our partners at MorphoSys, we are pleased to be moving forward with the initiation of a Phase 3 study in 2021,” said Steven Stein, M.D., Chief Medical Officer at Incyte.

“The preliminary firstMIND study results mark another important step as we explore the potential of tafasitamab as a backbone therapy,” said Dr. Malte Peters, Chief Research and Development Officer at MorphoSys. “Given the data available to date, including data from the L-MIND study, we believe that the mechanism of action, efficacy and safety profile of tafasitamab have the potential to make it a preferred combination partner as we seek to transform the standard of care in DLBCL. We are committed to developing innovative therapies to battle this aggressive disease for the benefit of patients with DLBCL, and look forward to beginning the planned frontMIND in the first half of 2021.”

In addition to the firstMIND data presented today, the long-term L-MIND analyses showed that treatment with tafasitamab plus lenalidomide resulted in durable responses after ≥2 years of follow-up. At the time of analysis, patients with complete responses (CR) continued to experience durable treatment responses, including long duration of response (DoR) and overall survival (OS). The data also showed that tafasitamab plus lenalidomide taken for 12 cycles, followed by tafasitamab until progression, did not result in any unexpected safety signals².

In July 2020, the FDA approved Monjuvi^® (tafasitamab-cxix), a humanized Fc-modified cytolytic CD19-targeting monoclonal antibody, 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)³.

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.

About Diffuse Large B-cell Lymphoma (DLBCL)

DLBCL is the most common type of non-Hodgkin lymphoma in adults worldwide⁴, characterized by rapidly growing masses of malignant B-cells in the lymph nodes, spleen, liver, bone marrow or other organs. It is an aggressive disease with about one in three patients not responding to initial therapy or relapsing thereafter⁵. In the United States each year, approximately 10,000 patients are diagnosed with relapsed or refractory DLBCL who are not eligible for autologous stem cell transplant (ASCT)^6,7,8.

About firstMIND

The firstMIND (NCT04134936) trial is a Phase 1b, randomized study of tafasitamab + R-CHOP (Arm A) or tafasitamab + lenalidomide + R-CHOP (Arm B) in patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL). The study includes a safety run-in phase and a main phase. In the safety run-in phase, 24 patients were enrolled. The primary objective is to assess safety; secondary objectives include objective response rate, PET negative complete response (PET-CR) rate at end of treatment, progression-free survival, event-free survival, long-term safety, pharmacokinetics and immunogenicity of tafasitamab.

About Tafasitamab

Tafasitamab is a humanized Fc-modified cytolytic CD19 targeting monoclonal antibody. 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).

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 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 (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 January 2020, MorphoSys and Incyte entered into a collaboration and licensing agreement to further develop and commercialize tafasitamab globally. Monjuvi^® is being co-commercialized by Incyte and MorphoSys in the United States. Incyte has exclusive commercialization rights outside the United States.

A marketing authorization application (MAA) seeking the approval of tafasitamab in combination with lenalidomide in the EU has been validated by the European Medicines Agency (EMA) and is currently under review for the treatment of adult patients with relapsed or refractory DLBCL, including DLBCL arising from low grade lymphoma, who are not candidates for ASCT.

Tafasitamab is being clinically investigated as a therapeutic option in B-cell malignancies in a number of ongoing combination trials.
