On May 11, 2021 Incyte (NASDAQ:INCY) and MorphoSys AG (FSE:MOR; NASDAQ:MOR) reported that the first patient has been dosed in the pivotal Phase 3 frontMIND study evaluating tafasitamab and lenalidomide in addition to rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) compared to R-CHOP alone as first-line treatment for high-intermediate and high-risk patients with untreated diffuse large B-cell lymphoma (DLBCL) (Press release, Incyte, MAY 11, 2021, View Source [SID1234579665]). Tafasitamab is a humanized, monoclonal antibody designed to effectively target the B-cell specific antigen CD19 and to induce immune cell activation.

"While more than half of DLBCL patients can be cured with an aggressive chemotherapy regimen, current outcomes for high-risk patients are poor," said Mike Akimov, M.D., Ph.D., Head of Global Drug Development, MorphoSys. "We believe we may be able to make a difference for those DLBCL patients by adding the combination of tafasitamab and lenalidomide to R-CHOP, a current standard of care."
Each year, approximately 30,000 patients are diagnosed with DLBCL in the U.S. alone1,2. R-CHOP is a current standard of care for patients with previously untreated DLBCL, but about 40% of patients do not respond to R-CHOP or relapse – particularly those with high-intermediate and high-risk disease3.
"Despite improvements in treatment for patients with DLBCL, there continues to be a significant medical need for additional therapies with improved outcomes," said Peter Langmuir, M.D., Group Vice President, Oncology Targeted Therapeutics, Incyte. "We are pleased to have initiated the frontMIND study as we seek meaningful, new options for newly diagnosed, high-risk patients with DLBCL."
In December 2020, encouraging preliminary data from firstMIND, the ongoing Phase 1b, open-label, randomized study on the safety and efficacy of R-CHOP plus either tafasitamab or tafasitamab plus lenalidomide for patients with newly diagnosed DLBCL, were presented at the American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting. The data showed a preliminary response rate of 91.1% across both arms in a patient population that overall had a poor prognosis, and that the combination of tafasitamab, lenalidomide and R-CHOP has an acceptable tolerability profile. These results informed and supported further investigation of the tafasitamab combination in the frontMIND study.
In July 2020, the FDA approved Monjuvi (tafasitamab-cxix) 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)4.
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 worldwide5, 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 40% of patients not responding to initial therapy or relapsing thereafter, leading to a high medical need for new, effective therapies, especially for patients who are not eligible for an autologous stem cell transplant in this setting6.
About frontMIND
The frontMIND (NCT04824092) trial is a randomized, double-blind, placebo-controlled, global Phase 3 clinical study in previously untreated high-intermediate and high-risk DLBCL patients that is conducted in partnership with the German Lymphoma Association (GLA), the Italian Lymphoma study group and the US Oncology Network.
The study aims to enroll approximately 880 DLBCL patients to receive either tafasitamab plus lenalidomide in addition to rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) or R-CHOP alone. The primary endpoint is investigator-assessed progression-free survival, according to Lugano 2014 criteria, and key secondary endpoints include event-free survival by investigator, overall survival, metabolic complete response rate by a Blinded Independent Review Committee, and overall response rate.

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.
