Plain-language summary
This phase Ib/II clinical trial tests the safety, side effects, and effectiveness of mosunetuzumab with chemotherapy for the treatment of patients with untreated, c-Myc rearrangement positive, high grade B cell lymphoma or diffuse large B cell lymphoma. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Immunotherapy with monoclonal antibodies, such as mosunetuzumab, 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 etoposide, doxorubicin, vincristine, cyclophosphamide and prednisone work in different ways to stop the growth of cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving mosunetuzumab with chemotherapy may be safe, tolerable and/or effective in treating patients with untreated, c-Myc rearrangement positive, high grade B cell lymphoma or diffuse large B cell lymphoma.

Inclusion Criteria:
* For both phases of the study, participant must be 18-75 years of age and have previously untreated high-grade B cell lymphoma (HGBCL) or diffuse large B cell lymphoma (DLBCL), including transformed DLBCL per the World Health Organization (WHO) 2022 classification, and with documented c-Myc rearrangement on fluorescence in situ hybridization (FISH) testing. Eligible types of c-Myc rearrangements will be performed by FISH testing and may include any single MYC rearrangement (single-hit lymphoma), Double hit (DHL) lymphoma or and triple hit (THL) lymphoma defined by translocations of MYC and BCL2 (DHL) and BCL6 (THL)
* Pathology must be verified and confirmed by university pathologists at the enrolling institution and centrally (OHSU) for any biopsies read outside of either institution
* Stage II or higher and International Prognostic Index (IPI) score of 2-5
* Able to comply with the study protocol and procedures, in the investigator's judgment
* At least one bi-dimensionally measurable nodal lesion, defined as ≥ 1.5 cm in its longest dimension, or one bi-dimensionally measurable extranodal lesion, defined as ≥ 1.0 cm in its longest diameter
* Confirmed availability of archival or freshly collected tumor tissue before study enrollment
* Eastern Cooperative Oncology Group Performance Status of 0, 1, or 2
* Left ventricular ejection fraction (LVEF) defined by multiple-gated acquisition (MUGA) scan or echocardiogram (ECHO) within the institutional limits of …
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.
What they're measuring
1
Incidence of dose limiting toxicities (DLTs) (phase Ib)
Timeframe: From the first dose of mosunetuzumab to the end of cycle 2 (1 cycle = 21 days)
2
Proportion of patients with complete response by positron emission tomography-computed tomography (PET-CT) (phase II)
