What the trial was testing
The trial enrolled 117 patients with lymphoma. The study was sponsored by Hoffmann-La Roche and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was an early-stage trial — researchers are still confirming safety and getting an early look at how well the treatment works. Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
85% complete response rate adding mosunetuzumab to CHOP.
Blood · 2023 · NCT03677141
These findings — that rate on mosunetuzumab + CHOP in previously untreated diffuse large B-cell lymphoma — were published in the Blood and represent the headline result of the study.
Researchers tracked outcomes across 117 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with lymphoma, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
Mosunetuzumab (Lunsumio) is FDA-approved for relapsed follicular lymphoma but is not yet approved as front-line DLBCL therapy. Standard front-line DLBCL treatment is R-CHOP, with newer options like polatuzumab + R-CHP (Polivy + R-CHP) FDA-approved for selected patients. Ask a hematologist about the best regimen for your case.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

Chimeric Antigen Receptor Natural Killer Cell Therapy for High-risk Lymphoma Patients With Primary Sjogren's Syndrome
This study is a phase I-II clinical trial of CAR-NK cell therapy for high-risk lymphoma patients with primary Sjogren's syndrome (pSS). The aim is to determine the optimal dose of CAR-NK cells and evaluate the safety and efficacy of increasing doses of iC9/CAR19/IL15 CB-NK cell therapy. Use i3+3 based design to increase dosage. Dose limiting toxicity (DLT) is defined as the occurrence of CRS within 2 weeks after cell infusion, requiring transfer to the intensive care unit, or grade III-IV acute graft-versus-host disease within 40 days after infusion, or grade 3-5 allergic reactions related to CAR-NK cell infusion. For the purpose of i3+3 design, efficacy is defined as a reduction in the high-risk of lymphoma in pSS patients and at least partial relief of dry mouth and eye symptoms on the 30th day after CAR-NK cell infusion.
Living Well With Lymphoma
In this study the investigators are proposing to evaluate the efficacy, sustainability, and mechanisms of 3 months of individualized counseling of the FRD delivered by registered dietitians, over 8 sessions by phone/video conferencing on fatigue, quality of life, and associated symptoms in persistently fatigued lymphoma cancer survivors compared to 3 months of individualized counseling of the attention control (matched for time and frequency of interactions with the FRD) the General Health Curriculum (GHC). The investigators will randomize and follow 68 lymphoma cancer survivors; accounting for a \~10% drop out rate to achieve a target of 60 patients that will complete the study. The investigators hypothesize that persistently fatigued lymphoma cancer survivors will experience improvements in fatigue, quality of life, and symptoms commonly associated with fatigue, which are then maintained at 15-months post-enrollment; and decreased CRP and alterations in inflammation-associated DNA methylation consistent with reduced inflammation from following the FRD as compared to the GHC.
