Mosunetuzumab for adults with relapsed/refractory follicular lymphoma after at least two prior therapies (compassionate use)
Official title: Retrospective, Multicenter Observational Study to Evaluate the Response to Treatment With Mosunetuzumab in Relapsed/Refractory Follicular Lymphoma (FL) After at Least Two Lines of Therapy, Within the Compassionate Use Program (CUP).
Run by IRCCS San Raffaele · NCT07278921 · Data updated 2026-11-12
This project will see if the antibody drug mosunetuzumab helps adults with follicular lymphoma that has come back or stopped responding after at least two prior treatments when given through a compassionate use program.

Is this trial a fit for you?
✓Likely a good fit
Eligible candidates are adults (>18) with relapsed/refractory follicular lymphoma who received mosunetuzumab via the compassionate use program after at least two prior therapies and agreed to use of their medical data.
✕Probably not a fit
Patients under 18, those with other lymphoma types, or people who were not treated with mosunetuzumab through the compassionate use program would not be represented and therefore would not benefit from this analysis.

What this trial studies
This is a retrospective, multicenter observational review of medical records from patients with relapsed/refractory follicular lymphoma who received mosunetuzumab through a compassionate use program, led by IRCCS Ospedale San Raffaele in Milan. The analysis focuses on adults who had at least two prior lines of therapy and provided consent for use of their clinical data. Investigators will extract response rates, duration of response, progression-free survival estimates, and recorded adverse events from routine care documentation. No new treatments or visits are required for participants because the work analyzes existing clinical data to describe real-world outcomes.
Why it matters
Potential benefit: If successful, the analysis could show real-world effectiveness and safety of mosunetuzumab in heavily pretreated follicular lymphoma and help support expanded access or future prospective trials.
How similar studies have gone: Previous clinical trials of mosunetuzumab, a CD20xCD3 bispecific antibody, have shown promising response rates in relapsed/refractory follicular lymphoma, so this work complements existing trial data with real-world experience.
