Conditions
Detailed Description
PRIMARY OBJECTIVES:
I. Determine the safety and tolerability of treatment with glofitamab and ibrutinib (GLIB) for previously untreated MCL in patients with high risk or age ≥ 65 yrs. (Phase Ib) I. Determine the efficacy of treatment with GLIB for previously untreated MCL in patients with high risk or age ≥ 65 yrs. (Phase II)
SECONDARY OBJECTIVES:
I. Assess the overall acute toxicity and tolerability of treatment with GLIB. II. Assess the preliminary efficacy of treatment with GLIB based on clinical response.
III. Assess survival in the absence of progressive disease, recurrence of disease, or death due to any cause after treatment with GLIB.
IV. Assess the duration of clinical response and complete response to treatment with GLIB.
EXPLORATORY OBJECTIVES:
I. Evaluate response to treatment evaluated as minimal residual disease (MRD). II. Evaluate the differential impact of treatment on T cell populations in the tumor microenvironment.
OUTLINE:
Patients receive ibrutinib orally (PO) once daily (QD) on days 1-21 of cycles 1-17. Cycles repeat every 21 days for up to 17 cycles in the absence of disease progression or unacceptable toxicity. Patients receive glofitamab intravenously (IV) over 2-4 hours on days 8 and 15 of cycle 2 and then on day 1 of cycles 3-13. Cycles repeat every 21 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive obinutuzumab IV over 4 hours at least 7 days and 24 hours prior to first dose of glofitamab. Additionally, patients undergo echocardiography during screening, bone marrow biopsy on study, and computed tomography (CT) scans, fludeoxyglucose F-18 (FDG) positron emission tomography (PET)/computed tomography (CT) scans or magnetic resonance imaging (MRI), and blood sample collection throughout the study.
After completion of study treatments, patients are followed up every 3 months for up to 2 years.
