Incyte Announces Positive Topline Results from Pivotal Study of Tafasitamab (Monjuvi®/Minjuvi®) as a First-line Treatment for Diffuse Large B-Cell Lymphoma

- Phase 3 frontMIND trial evaluating the efficacy and safety of tafasitamab (Monjuvi^®/Minjuvi^®) and lenalidomide in addition to R-CHOP met its primary endpoint of progression-free survival (PFS)

- Based on these results, Incyte plans to file a supplemental Biologics License Application (sBLA) for tafasitamab and lenalidomide in addition to R-CHOP in first-line diffuse large B-cell lymphoma (DLBCL) in the first half of 2026

Incyte (NASDAQ:INCY) today announced positive topline results from the pivotal Phase 3 frontMIND trial evaluating the efficacy and safety of tafasitamab (Monjuvi^®/Minjuvi^®), a humanized Fc-modified cytolytic CD19 targeting monoclonal antibody, and lenalidomide in addition to R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) compared to R-CHOP alone as a first-line treatment for adults with newly diagnosed diffuse large B-cell lymphoma (DLBCL) with an International Prognostic Index (IPI) score of three to five (3-5) for patients >60 years of age, or age-adjusted IPI (aaIPI) of two to three (2-3) for patients ≤60 years of age.

The trial met its primary endpoint of progression-free survival (PFS) by investigator assessment (Hazard Ratio 0.75 [0.59,0.96]; p-value 0.019), according to Lugano 2014 criteria. The trial also met its key secondary endpoint of event-free survival (EFS) by investigator assessment. No new safety signals were observed.

"The frontMIND study results highlight the potential benefit of combining tafasitamab and lenalidomide with R-CHOP as an effective treatment option, offering the possibility of cures for more newly diagnosed DLBCL patients," said Steven Stein, M.D., Chief Medical Officer, Incyte. "Despite improvement in treatment for patients with DLBCL, outcomes for many high-risk patients are not optimal. We look forward to working with regulatory authorities globally and to providing a new treatment option for patients in the future."

DLBCL is the most common type of non-Hodgkin lymphoma (NHL) in adults worldwide, representing 40% of all cases.¹ It is characterized as an aggressive, fast-growing type of lymphoma that can emerge in lymph nodes or extranodal sites such as the gastrointestinal tract, skin and brain.² Each year, approximately 24,000 people in the U.S. and up to 36,000 people in Europe are diagnosed with DLBCL.^3,4,5,6 With about 40% of these patients not responding to initial therapy or relapsing thereafter^7,8, there is a high medical need for new, effective therapies.

Based on these positive results, Incyte expects to file a supplemental Biologics License Application (sBLA) for tafasitamab for the first-line treatment of adults with newly diagnosed DLBCL in the first half of 2026. The frontMIND data will 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 DLBCL not otherwise specified including DLBCL arising from low-grade lymphoma, and who are not eligible for autologous stem cell transplant. Additionally, tafasitamab was approved in combination with lenalidomide and rituximab by the FDA in June 2025 for adult patients with relapsed or refractory follicular lymphoma (FL). In November 2025, the EMA's Committee for Medicinal Products for Human Use issued a positive opinion recommending the approval of tafasitamab for patients with relapsed or refractory FL.

About frontMIND

The frontMIND trial (NCT04824092) is a randomized, double-blind, placebo-controlled, global Phase 3 study in patients with previously untreated diffuse large B-cell lymphoma (DLBCL).

The study has enrolled approximately 900 adults (≥18 to ≤80 years) and is evaluating the efficacy and safety of tafasitamab and lenalidomide in addition to R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) compared with R-CHOP alone.

The primary endpoint of the study is investigator-assessed progression-free survival (PFS) using the Lugano 2014 criteria. Key secondary endpoints include event-free survival (EFS) by investigator assessment and overall survival (OS).

About Tafasitamab (Monjuvi^®/Minjuvi^®)

Tafasitamab (Monjuvi^®/Minjuvi^®) is a humanized Fc-modified cytolytic CD19-targeting monoclonal antibody. 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). Incyte licenses exclusive worldwide rights to develop and commercialize tafasitamab from Xencor, Inc.

In the U.S., Monjuvi® (tafasitamab-cxix) is approved by the U.S. Food and Drug Administration in combination with lenalidomide and rituximab for the treatment of adult patients with relapsed or refractory follicular lymphoma (FL).

Monjuvi is not indicated and is not recommended for the treatment of patients with relapsed or refractory marginal zone lymphoma outside of controlled clinical trials.

Additionally, Monjuvi received accelerated approval in the United States 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).

In Europe, Minjuvi^® (tafasitamab) received conditional Marketing Authorization from the European Medicines Agency in combination with lenalidomide, followed by Minjuvi monotherapy, for the treatment of adult patients with relapsed or refractory DLBCL who are not eligible for ASCT.

• Infections. Serious infections, including infections that can cause death, have happened in people during treatment with MONJUVI and after the last dose. Tell your healthcare provider right away if you get a fever of 100.4°F (38°C) or above, or develop any signs and symptoms of an infection.

The most common side effects of MONJUVI include:

• Feeling tired or weak
• Diarrhea
• Cough
• Fever
• Swelling of lower legs or hands
• Respiratory tract infection
• Decreased appetite

These are not all the possible side effects of MONJUVI. Your healthcare provider will give you medicines before each infusion to decrease your chance of infusion reactions. If you do not have any reactions, your healthcare provider may decide that you do not need these medicines with later infusions. Your healthcare provider may need to delay or completely stop treatment with MONJUVI if you have severe side effects.

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Before you receive MONJUVI, tell your healthcare provider about all of your medical conditions, including if you:

• Have an active infection or have had one recently.
• Are pregnant or plan to become pregnant. MONJUVI may harm your unborn baby. You should not become pregnant during treatment with MONJUVI. Do not receive treatment with MONJUVI in combination with lenalidomide if you are pregnant because lenalidomide can cause birth defects and death of your unborn baby.
• You should use an effective method of birth control (contraception) during treatment and for at least 3 months after your final dose of MONJUVI.
• Tell your healthcare provider right away if you become pregnant or think that you may be pregnant during treatment with MONJUVI.
• Are breastfeeding or plan to breastfeed. It is not known if MONJUVI passes into your breastmilk. Do not breastfeed during treatment for at least 3 months after your last dose of MONJUVI.

You should also read the lenalidomide Medication Guide for important information about pregnancy, contraception, and blood and sperm donation.

Tell your healthcare provider about all the medications you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
