Testing the Addition of an Anti-Cancer Drug, Glofitamab, to the Usual Chemotherapy Treatment (Alternating R-CHOP/R-DHAP) for Previously Untreated Mantle Cell Lymphoma
16 participantsStarted 2026-08-20
Plain-language summary
This phase I trial tests the safety, side effects and best dose of glofitamab given with alternating cycles of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP)/ rituximab, dexamethasone, cytarabine, and cisplatin (R-DHAP) for the treatment of mantle cell lymphoma. Glofitamab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. 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). Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill cancer cells. It may also lower the body's immune response. Doxorubicin is in a class of medications called anthracyclines. Doxorubicin damages the cell's DNA and may kill cancer cells. It also blocks a certain enzyme needed for cell division and DNA repair. Vincristine is in a class of medications called vinca alkaloids. It works by stopping cancer cells from growing and dividing and may kill them. Prednisone and dexamethasone are in a class of medications called corticosteroids. They are used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Chemotherapy drugs, such as cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. Giving glofitamab may be safe, tolerable and/or effective in treating patients with mantle cell lymphoma.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patients must have histologically or cytologically confirmed previously untreated mantle cell lymphoma which is stage II bulky, stage III, or stage IV and fit for intensive chemotherapy. TP53 mutated patients are eligible
* Patients must exhibit measurable disease by PET or CT imaging with at least one site of disease \> 1.5 cm in longest dimension or documented bone marrow involvement
* Age ≥ 18 years to ≤ 75 years. Because no dosing or adverse event data are currently available on the use of glofitamab in combination with R-CHOP/R-DHAP in patients \< 18 years of age, children are excluded from this study
* Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 (Karnofsky ≥ 60%)
* Absolute neutrophil count ≥ 1,000/mcL
* Platelets ≥ 100,000/mcL
* Total bilirubin ≤ 2 × institutional upper limit of normal (ULN) unless total bilirubin elevation is attributable to Gilbert's syndrome or lymphomatous infiltration of the liver in whom total bilirubin must be \< 3 times ULN
* Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase \[SGOT\])/ alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase \[SGPT\]) ≤ 3 × institutional ULN
* Creatinine clearance ≥ 30 ml/min
* Left ventricular ejection fraction ≥ 45% by echocardiogram or Multiple-Gated Acquisition (MUGA) scan
* International Normalized Ratio (INR) or prothrombin time (PT) ≤ 1.5 × ULN in the absence of therapeutic anticoagulation
* Partial thromboplastin time (PTT) or…
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.
1Since this is a Phase 1 trial focused on finding a safe dose of glofitamab rather than proving it works, what does that mean for my personal risk if I were to consider participating?
2The trial is listed as 'not yet recruiting' — how far away is it from opening, and would waiting for it delay any standard treatment options I should be starting now?
3Glofitamab is being added to the standard R-CHOP/R-DHAP chemotherapy regimen — are there specific side effects from combining these treatments that I should be aware of and watch for?
4For my stage of mantle cell lymphoma, would the standard alternating R-CHOP/R-DHAP chemotherapy alone, without glofitamab, be a reasonable first path, and how would that compare to waiting for or joining this trial?
5Since the trial is primarily measuring dose-limiting toxicities, what types of serious adverse events have been seen with glofitamab in other studies, and how might those affect someone with my overall health situation?

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.
