Brief summary

This phase II/III trial tests adding glofitamab to standard of care chemoimmunotherapy in patients with Burkitt and high grade (double hit) B- cell lymphomas that are newly diagnosed, that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). Glofitamab 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. Obinutuzumab and rituximab are also monoclonal antibodies. They bind 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. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill cancer cells. 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. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill cancer cells. It may also lower the body's immune response. Prednisone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Methotrexate is in a class of medications called antimetabolites. It is also a type of antifolate. Methotrexate stops cells from using folic acid to make DNA and may kill cancer cells. Chemotherapy drugs, such as cytarabine and ifosfamide, 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. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Giving glofitamab with standard of care chemotherapy may work well for the treatment of newly diagnosed, relapsed or refractory Burkitt and high grade (double hit) B- cell lymphomas.

Detailed description

PRIMARY OBJECTIVES: I. To compare the progression free survival (PFS) of rituximab (R)-chemotherapy plus glofitamab versus R-chemotherapy alone in patients with newly diagnosed Burkitt lymphoma. II. To compare the PFS of R-chemotherapy plus glofitamab versus R-chemotherapy alone in patients with newly diagnosed high grade (double hit) B-cell lymphoma with MYC and BCL2 rearrangements. III. To determine the overall survival of obinutuzumab, rituximab, ifosfamine, carboplatin, etoposide (RICE), and glofitamab in patients with relapsed Burkitt lymphoma. SECONDARY OBJECTIVES: I. To compare the overall survival (OS) of R-chemotherapy plus glofitamab versus R-chemotherapy alone in patients with Burkitt lymphoma, and patients with high grade B-cell lymphoma with MYC and BCL2 rearrangements. II. To compare the safety and tolerability of glofitamab combined with R-chemotherapy versus R-chemotherapy alone in patients with Burkitt lymphoma, and patients with high grade B-cell lymphoma with MYC and BCL2 rearrangements. III. To determine the event free survival (EFS), complete response (CR) and overall response (OR) rates of obinutuzumab, RICE, and glofitamab in patients with relapsed Burkitt and high grade B-cell lymphoma. IV. To assess how many patients undergo transplant or chimeric antigen receptor T-cell therapy (CART) after treatment with obinutuzumab, RICE, and glofitamab for relapsed Burkitt lymphoma. EXPLORATORY OBJECTIVES: I. To assess patient reported outcomes in patients with Burkitt and double hit lymphoma at study enrollment, during treatment and at the end of therapy. II. To evaluate the completion rate of a lymphoma-specific patient assessment of life survey (PALS) for 7 patient directed questions on social determinants of health (SDH) and assess the impact of the survey collected data on outcomes for all enrolled patients.

Lastly, patients treated with prior immunotherapeutic agents with a history of any grade 3 events (except for grade 3 endocrinopathy managed with replacement therapy) or grade 1-2 events that did not resolve to baseline with treatment discontinuation are NOT eligible * RELAPSED BL AND HGL COHORT 3: Patients with a history of PML are NOT eligible * RELAPSED BL AND HGL COHORT 3: Patients who have received live, attenuated vaccines within 4 weeks prior to cycle 1 D1 of study treatment are NOT eligible

Design outcomes

Primary

MeasureTime frameDescription
Progression free survival (PFS) (cohort 1) (phase II)from randomization to the time of documented disease progression or death due to any causeThe median PFS will be summarized by sex with corresponding 95% confidence intervals.
PFS (cohort 1) (phase III)At 24 monthsPFS defined as from randomization to the time of documented disease progression or death due to any cause. Will be as estimated using the methods of Kaplan and Meier. The median PFS and the 24-month PFS rates will be summarized by sex with corresponding 95% confidence intervals.
PFS (cohort 2) (phase II)From randomization to the time of documented disease progression or death due to any cause, up to 5 yearsThe median PFS will be summarized by sex with corresponding 95% confidence intervals.
PFS (cohort 2) (phase III)At 24 monthsPFS defined as from randomization to the time of documented disease progression or death due to any cause. Will be as estimated using the methods of Kaplan and Meier. The median PFS and the 24-month PFS rates will be summarized by sex with corresponding 95% confidence intervals.
Overall survival (cohort 3)At 12 months after start of treatment

Secondary

MeasureTime frameDescription
Overall survival (OS)From randomization to the time of death due to any cause, up to 5 yearsWill be evaluated between the treatment arms for each of the cohorts. Kaplan Meier methods will be used to estimate key aspects of the OS distributions for each of the treatment arms, and logrank tests will be used to compare these distributions between arms.
Event free survival (EFS)From randomization date until the earlier of non-protocol lymphoma therapy, disease progression or death from any cause, up to 5 yearsWill be evaluated between the treatment arms for each of the cohorts. Kaplan Meier methods will be used to estimate key aspects of the EFS distributions for each of the treatment arms, and logrank tests will be used to compare these distributions between arms.
Overall response rate (ORR)Up to 5 yearsDefined as the number of patients achieving complete or partial response according to either the computed tomography(CT)-based or positron emission tomography (PET)-CT-based Lugano criteria, divided by the number of evaluable patients. will be estimated by treatment arm, and a 95% binomial confidence interval for the estimated ORR will be provided. Will be evaluated between the treatment arms for each of the cohorts.
Complete response rateUp to 5 yearsDefined as the number of patients achieving complete response according to either the CT-based or PET-CT-based Lugano criteria, divided by the number of evaluable patients. The CR rate will be estimated by treatment arm, and a 95% binomial confidence interval for the estimated CR rate will be provided.
Transplant or chimeric antigen receptor t-cell (CAR-T) rate (cohort 3)Up to 5 yearsDefined as the number of Cohort 3 patients who undergo transplant or CAR-T after treatment with Rituximab-Ifosfamide-Carboplatin-Etoposide plus Glofitamab, divided by the number of Cohort 3 patients who receive at least one dose of protocol therapy. The transplant or CAR-T rate will be estimated and the corresponding 95% binomial confidence interval will be provided.
Incidence of adverse events (AEs)Up to 5 yearsWill be summarized per the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5 and Patient Reported Outcome-CTCAE, and where toxicities will be defined as adverse events that are deemed to be at least possibly treatment-related. The maximum grade for each type of treatment-related AE will be recorded for each patient, and the frequency of each will be summarized by treatment arm. Frequency tables and graphical evaluations of AEs and treatment-related AEs will be summarized and evaluated to assess if there are any patterns or differences in the rates or types of AEs.
