Study Summary

This trial is testing a new cancer treatment that combines immunotherapy and chemotherapy.

Who is the study for?
Adults with untreated diffuse large B-cell lymphoma or grade 3B follicular lymphoma, who have not received prior therapy for lymphoma. Participants must have adequate organ function, no severe allergies to monoclonal antibodies, and agree to use contraception. Excluded are those with certain infections (HIV, Hepatitis B/C), active central nervous system metastases, other progressing cancers requiring treatment, or conditions that could interfere with the trial.Check my eligibility
What is being tested?
The trial is testing a combination of three monoclonal antibodies (tafasitamab, retifanlimab, rituximab) as prephase treatment along with standard CHOP chemotherapy in patients with diffuse large B-cell lymphoma. The goal is to see if this combination can more effectively kill cancer cells than current treatments.See study design
What are the potential side effects?
Potential side effects include reactions related to the immune system's increased activity such as inflammation in various organs and infusion-related reactions. Chemotherapy may cause nausea, hair loss, fatigue and increase infection risk due to lowered blood cell counts.

Experimental Treatment
Group I: Treatment (TRR, CHOP)Experimental Treatment14 Interventions
PREPHASE THERAPY: Patients receive tafasitamab IV over 30 minutes on days 1, 8, and 15 of each cycle, rituximab and hyaluronidase human SC on day 1 of each cycle, and retifanlimab IV over 30 minutes on day 8 of each cycle. Treatment repeats every 21 days for 2 cycles in the absence of disease progression or unacceptable toxicity. COMBINATION THERAPY: After completion of prephase therapy or if patients progress during prephase therapy, patients receive tafasitamab IV over 30 minutes, retifanlimab IV over 30 minutes, rituximab and hyaluronidase human SC, cyclophosphamide IV, doxorubicin IV, and vincristine IV on day 1 of each cycle. Patients also receive prednisone PO on days 1-5 of each cycle. Treatment repeats every 21 days for 4-6 cycles in the absence of disease progression or unacceptable toxicity.
