About this study
Official title: A Phase I Study of Glofitamab With Alternating R-CHOP/R-DHAP in Previously Untreated Mantle Cell Lymphoma
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.

CYCLES 2, 4 and 6: Patients receive rituximab IV, and cisplatin IV over 24 hours on day 1, as well as cytarabine IV on day 2 and dexamethasone PO on days 1-4. Patients also receive glofitamab IV, over 2-8 hours, on days 8 and 15 of cycle 2 and on day 8 of subsequent cycles. Cycles repeat every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. MAINTENANCE: Patients receive glofitamab IV on day 1 of each cycle. Cycles repeat every 21 days for a total of 24 months of treatment, in the absence of disease progression or unacceptable toxicity. |
Who may qualify
- Ages
- 18 to 75 years
- Sex
- All
- Healthy volunteers
- Not accepted
- Age groups
- Adult, Older adult
Key inclusion criteria (22 listed)
- 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
Key exclusion criteria (41 listed)
- Patients who received prior treatment for MCL, including chemotherapy, bispecific antibody therapy, or other cytotoxic or cellular therapy including autologous hematopoietic stem cell transplant (autoHCT). Since this study aims to evaluate safety and efficacy in previously untreated patients by using this regimen as a first-line therapy, prior systemic therapy would potentially bias and affect endpoints and results
- Patients who have not recovered from AEs due to prior anti-cancer therapy (i.e., have residual toxicities > grade 1) with the exception of alopecia
- Patients who are receiving any other investigational agents
- Patients with lymphoma that shows active and uncontrolled CNS involvement; uncontrolled CNS involvement may require different systemic therapy in addition to CNS directed therapy, which would interfere with the study regimen and sequence of drug administration
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to glofitamab or other agents used in study
Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.

Primary outcome
Incidence of adverse events (AEs)
Time frame: Up to 5 years
Will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5 for all AEs other than cytokine release syndrome (CRS), immune effector cell associated neurotoxicity syndrome (ICANS), and hemophagocytic lymphohistiocytosis (HLH). CRS, ICANS, and HLH will be graded according to American Society for Transplantation and Cellular Therapy criteria.
Dose limiting toxicity (DLT)
Time frame: From cycle 2, day 8 to cycle 5 day 1 (cycle length = 21 days)
DLT is defined as any grade 4 or higher CRS event, any grade CRS event that does not improve to < grade 2 within 72 hours, any grade 3 or higher neurologic toxicity event including ICANS events, any grade 3 or higher non-hematologic toxicity, grade 3 aspartate aminotransferase (AST) or alanine aminotransferase (ALT) elevation that does not resolve to grade 2 or less within 14 days, grade 4 AST or ALT is a DLT regardless of duration, grade 4 thrombocytopenia lasting more than 7 days, grade 3 thrombocytopenia with hemorrhage, grade 3 thrombocytopenia lasting ≥ 28 days or grade 4 neutropenia lasting ≥ 14 days despite the use of growth factors.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Biospecimen Collection, Cisplatin and Computed Tomography in people with Ann Arbor Stage II Mantle Cell Lymphoma and Ann Arbor Stage III Mantle Cell Lymphoma, run by National Cancer Institute (NCI).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 22 inclusion and 41 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 6 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of adverse events (AEs) (time frame: Up to 5 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2026.
