Summary

This trial is testing a combination of two immunotherapy drugs to treat patients with either follicular lymphoma or diffuse large B cell lymphoma that has returned or doesn't respond to treatment. The immunotherapy drugs are pembrolizumab and either rituximab or obinutuzumab. Rituximab and obinutuzumab are monoclonal antibodies that bind to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. The drugs may help kill more cancer cells.

Who is the study for?
This trial is for adults with relapsed or refractory follicular lymphoma or diffuse large B cell lymphoma. They must have tried certain treatments like CD20 antibody therapy, not be eligible for high-dose chemotherapy and stem cell transplant, and lack better treatment options. Participants need a minimum hemoglobin level, measurable disease, good performance status (able to carry out daily activities), adequate organ function, and agree to use contraception.
What is being tested?
The study tests pembrolizumab combined with either rituximab or obinutuzumab in patients whose lymphoma has returned after treatment or hasn't responded to previous therapies. Pembrolizumab is an immunotherapy drug that may help the immune system attack cancer cells; rituximab and obinutuzumab are antibodies targeting specific proteins on cancer cells.
What are the potential side effects?
Potential side effects include reactions at the infusion site, fatigue, fever, chills, body aches similar to flu symptoms from rituximab or obinutuzumab. Pembrolizumab can cause immune-related adverse effects such as inflammation of organs like lungs (pneumonitis) or intestines (colitis), skin rash, liver enzyme elevation indicating liver inflammation.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Arm II (pembrolizumab, obinutuzumab)Experimental Treatment3 Interventions
INDUCTION: Patients receive pembrolizumab IV over 30 minutes on day 1. Treatment repeats every 3 weeks for 4 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive obinutuzumab IV on days 1, 8, and 15 of cycle 1, and on day 1 of cycle 2. EXTENDED THERAPY: Patients with at least a partial response receive pembrolizumab IV over 30 minutes on day 1. Cycles repeat every 3 weeks for up to 2 years (35 cycles) in the absence of disease progression or unacceptable toxicity. Patients with stable disease or better, who are experiencing clinical benefit in the judgment of the investigator, may receive obinutuzumab IV on day 1 of cycles 5, 9, 13, 17, 21, and 25.
