Summary
This trial is studying a new drug combination to treat primary mediastinal B-cell lymphoma that has recurred after prior treatment.
Who is the study for?
Adults (≥18 years) with primary mediastinal B-cell lymphoma that's come back or didn't respond to at least two treatments, or relapsed within a year of initial treatment. They must have measurable cancer on scans and agree to use effective contraception. People can't join if they've had certain other cancers, severe allergies to trial drugs, active infections like hepatitis or HIV, recent heart issues, uncontrolled diseases that could affect the study, or are pregnant.
What is being tested?
The trial is testing pembrolizumab combined with CAR T-cell therapy (axicabtagene-ciloleucel or lisocabtagene maraleucel), plus chemotherapy drugs cyclophosphamide and fludarabine. It aims to see if this mix can help people whose B-cell lymphoma has returned after previous treatments.
What are the potential side effects?
Possible side effects include reactions related to immune system activation such as fever and fatigue; organ inflammation; infusion-related symptoms; blood cell count changes leading to increased infection risk; and potential harm to unborn babies.

Experimental Treatment
Group I: PEMBROLIZUMABExperimental Treatment4 Interventions
* Participants will undergo (leukapheresis) for manufacturing of commercial product as per standard of care (SOC) Cycle 1 Day -21or earlier
* Pembrolizumab will be administered per protocol on cycle 1 day -20 and on day +1 following Chimeric Antigen Receptor (CAR) Therapy Infusion infusion, every 3 weeks for up to 2 years, unless there is confirmed progression of disease or unacceptable toxicity.
* Upon the completion of successful manufacturing, patients will undergo lymphodepleting chemotherapy (fludarabine, cyclophosphamide) for chimeric antigen receptor (CAR) therapy infusion as per SOC.
* Participants will receive Chimeric Antigen Receptor (CAR) Therapy Infusion (SOC) on day 0 in the hospital and will remain in the inpatient setting for observation for a minimum of 7 days or until CAR T-cell toxicities resolve to grade 1 or better. The choice of CAR-T product will be left to the discretion of the treating investigator.
