Tafasitamab, Retifanlimab, and Rituximab in Combination With Standard Therapy for the Treatment of Diffuse Large B-cell Lymphoma
United States33 participantsStarted 2023-01-26
Plain-language summary
This phase I/II trial tests the safety of tafasitamab, retifanlimab, and rituximab (TRR) as a prephase treatment and in combination with standard therapy consisting off cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or polatuzumab vedotin, cyclophosphamide, doxorubicin, and prednisone (PolaCHP) in patients with untreated diffuse large B-cell lymphoma. Tafasitamab, retifanlimab, and rituximab are monoclonal antibodies. Tafasitamab binds to a protein called CD19, which is found on B-cells (a type of white blood cell) and some types of cancer cells. Rituximab binds to a protein called CD20, which is also found on B-cells and some cancer cells. These monoclonal antibodies may help the immune system kill cancer cells. Immunotherapy with other monoclonal antibodies, such as retifanlimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as CHOP and PolaCHP, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving TRR in combination with CHOP or PolaCHP may kill more cancer cells.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patients with previously untreated diffuse large B cell lymphoma or grade 3B follicular lymphoma (of any stage). Patients may have de novo DLBCL, and /or any of the following:
* Composite lymphomas, which include both diffuse DLBCL and another histology (most commonly follicular lymphoma) in the same lymph node,
* Transformed lymphoma with DLBCL histology, as long as the patient has not received prior therapy for lymphoma,
* Discordant presentations, such as DLBCL in a lymph node and low-grade lymphoma such as follicular lymphoma in the bone marrow, and
* High grade B-cell lymphoma (including "double hit" lymphomas or high grade B-cell lymphoma-not otherwise specified \[HGBCL-NOS\]) is permitted if the patient is not eligible for or declines intensive therapy
* Be willing and able to provide written informed consent/assent for the trial
* Be \>= 18 years of age on day of signing informed consent
* Have measurable disease, including at least 1 nodal site measuring 1.5 cm or 1 extranodal site measuring 1.0 cm in longest dimension on computed tomography (CT) or fludeoxyglucose F-18-positron emission tomography (FDG-PET)
* Have a performance status of 0-2 on the Eastern Cooperative Oncology Group (ECOG) performance scale (PS)
* Absolute neutrophil count (ANC) \>= 1,000/mcL except in case of marrow infiltration by lymphoma
* Platelets \>= 75,000/mcL except in cases of marrow infiltration by lymphoma
* Serum creatinine clearance (CrCl) must be \>= 30…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
