Incyte Announces Positive Topline Results from Pivotal Study of Tafasitamab (Monjuvi®) in Relapsed or Refractory Follicular Lymphoma

Rhea-AI Summary

Incyte (Nasdaq: INCY) announced positive topline results from the pivotal Phase 3 inMIND trial evaluating tafasitamab (Monjuvi®) in combination with lenalidomide and rituximab for relapsed or refractory follicular lymphoma (FL). The trial met its primary endpoint of progression-free survival (PFS) and key secondary endpoints. Based on these results, Incyte plans to file a supplemental Biologics License Application for tafasitamab in this indication by year-end.

Follicular lymphoma is the most common indolent form of B-cell non-Hodgkin lymphoma, with treatment options for relapsed or refractory cases. Tafasitamab is already approved for certain diffuse large B-cell lymphoma patients in the US and Europe.

• Phase 3 inMIND trial met its primary endpoint of progression-free survival in follicular lymphoma
• Trial also met key secondary endpoints, including PFS in the overall population
• No new safety signals with tafasitamab were observed
• Incyte plans to file a supplemental Biologics License Application by year-end

Negative

• None.

Insights

Oncology Specialist

This is a significant development in the treatment of relapsed or refractory follicular lymphoma (FL). The positive results from the Phase 3 inMIND trial demonstrate that adding tafasitamab to the standard lenalidomide and rituximab regimen significantly improves progression-free survival (PFS). This is important because FL, while slow-growing, often relapses after initial treatment.

The trial's success in meeting both primary and key secondary endpoints, including PFS and complete response rate, suggests a potentially game-changing treatment option for FL patients who have failed previous therapies. With over 17,000 new cases of relapsed or refractory FL annually in major markets, this could represent a substantial market opportunity for Incyte.

Importantly, no new safety signals were observed, which is reassuring given the potential for increased toxicity when combining multiple therapies. This positive safety profile could facilitate regulatory approval and adoption in clinical practice.

Financial Analyst

These results are likely to have a positive impact on Incyte's financial outlook. The company's plan to file a supplemental Biologics License Application by year-end could lead to an expanded market for tafasitamab, potentially driving significant revenue growth. The follicular lymphoma market is substantial and a new effective treatment option could capture a meaningful share.

Investors should note that tafasitamab is already approved for diffuse large B-cell lymphoma, so this expansion into FL represents a broadening of the drug's market potential. The positive trial results may also enhance Incyte's position in negotiations with payers and could lead to increased adoption by oncologists.

However, it's important to consider potential competition in the FL space and the time it may take for regulatory approval and market penetration. Overall, this news is likely to be viewed favorably by the market, potentially boosting Incyte's stock in the short term.

Medical Research Analyst

The inMIND trial results represent a significant advancement in FL treatment research. The study's design, comparing tafasitamab plus lenalidomide and rituximab to lenalidomide and rituximab alone, addresses a critical question in the field: can we improve upon current standard therapies?

The positive PFS results, confirmed by both investigator assessment and blinded independent review, provide robust evidence of tafasitamab's efficacy. The consistency between these two assessment methods strengthens the reliability of the findings. Additionally, the improved complete response rate in FDG-avid FL patients is particularly noteworthy, as it suggests a deeper and potentially more durable response.

These results could pave the way for new combination strategies in FL treatment. They also highlight the potential of targeted therapies like tafasitamab in improving outcomes for patients with indolent lymphomas, opening avenues for further research in this area.

- Phase 3 inMIND trial evaluating the efficacy and safety of tafasitamab (Monjuvi^®) or placebo in combination with lenalidomide and rituximab met its primary endpoint of progression free survival (PFS) in relapsed or refractory follicular lymphoma (FL)

- Based on these results, Incyte expects to file a supplemental Biologics License Application for tafasitamab in combination with lenalidomide and rituximab in FL by the end of the year

WILMINGTON, Del.--(BUSINESS WIRE)-- Incyte (Nasdaq: INCY) today announces positive topline results from the pivotal Phase 3 inMIND trial evaluating the efficacy and safety of tafasitamab (Monjuvi^®), a humanized Fc-modified cytolytic CD19 targeting monoclonal antibody, or placebo in combination with lenalidomide and rituximab compared to lenalidomide and rituximab alone in patients with relapsed or refractory follicular lymphoma (FL).

The trial met its primary endpoint of progression free survival (PFS) by investigator assessment in FL. It also met key secondary endpoints of PFS in the overall population by investigator assessment as well as the positron-emission tomography-complete response rate in the FDG-avid FL population. In addition, the secondary endpoint of PFS results by blinded independent review are consistent with investigator based PFS results. No new safety signals with tafasitamab were observed.

“While many patients with follicular lymphoma initially benefit from first-line treatment, relapse of the disease is common, underscoring the need for additional therapies,” said Steven Stein, M.D., Chief Medical Officer, Incyte. “These results demonstrate the potential of tafasitamab added to the standard of care to be a meaningful new treatment option for patients with FL whose disease has progressed after at least one prior therapy.”

FL is the most common indolent, or slow growing, form of B-cell non-Hodgkin lymphoma (NHL) and accounts for approximately 13-26% of overall NHL cases.^1,2,3,4,5 There are limited treatment options for the more than 17,000 new cases of relapsed or refractory FL treated every year in the United States, Europe and Japan.⁶

Based on these positive results, Incyte expects to file a supplemental Biologics License Application for tafasitamab for the treatment of patients with FL who have failed at least one prior systemic anti-CD20 immunotherapy or chemo-immunotherapy by the end of the year.

The full inMIND data will also 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 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. Tafasitamab is marketed as Monjuvi^® (tafasitamab-cxix) in the United States and Minjuvi^® (tafasitamab) in Europe and Canada.

About inMIND

A global, double-blind, randomized, controlled Phase 3 study, inMIND (NCT04680052) evaluated the clinical benefit of tafasitamab and lenalidomide as an add-on to rituximab compared with lenalidomide alone as an add-on to rituximab in patients with relapsed or refractory follicular lymphoma (FL) Grade 1 to 3a or relapsed or refractory nodal, splenic or extranodal marginal zone lymphoma (MZL). The study enrolled a total of 654 adults (age ≥18 years).

The primary endpoint of the study is progression-free survival (PFS) by investigator assessment in the FL population, and the key secondary endpoints are PFS in the overall population as well as positron emission tomography complete response (PET-CR) and overall survival (OS) in the FL population.
