The severity of the toxicities will be graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v)5.0. AEs and clinically significant laboratory abnormalities meeting grade 3 4 or 5 will be summarized by maximum intensity and relationship to study drug for the first 6 participants from the initiation of the study drug combination (Cycle 2 Day 8 (C2D8)) through the end of cycle 2 (Cycle 2 Day 21 (C2D21)), approximately 14 days.
CR will be defined as the proportion of treated participants who experience a CR per Lugano criteria among evaluable participants. The Lugano classification recommends the Deauville five-point scale for reporting response by Fluorodeoxyglucose (FDG) Positron Emission Tomography (PET)/Computerized tomography (CT): (1) no uptake or no residual uptake (when used interim) (2) slight uptake, but below blood pool (mediastinum) (3) uptake above mediastinal, but below or equal to uptake in the liver (4) uptake slightly to moderately higher than liver (5) markedly increased uptake or any new lesion (on response evaluation) from cycle 5 Day 1 through the follow-up period up to 94 weeks.
The proportion of participants with a diagnosed incident of CRS for the first 6 participants from the initiation of the study drug combination (Cycle 2 Day 8 (C2D8)) through the end of cycle 2 (Cycle 2 Day 21 (C2D21)), approximately 14 days, and graded according to the American Society of Transplantation and Cellular Therapy (ASTCT) criteria will be reported.
The proportion of participants with a diagnosed incident of ICANS for the first 6 participants from the initiation of the study drug combination (Cycle 2 Day 8 (C2D8)) through the end of cycle 2 (Cycle 2 Day 21 (C2D21)), approximately 14 days, and graded according to the American Society of Transplantation and Cellular Therapy (ASTCT) criteria will be reported.
The proportion of participants with a diagnosed incident of HLH for the first 6 participants from the initiation of the study drug combination (Cycle 2 Day 8 (C2D8)) through the end of cycle 2 (Cycle 2 Day 21 (C2D21)), approximately 14 days, and graded according to the American Society of Transplantation and Cellular Therapy (ASTCT) criteria will be reported.
| Arm | Type | Description |
|---|---|---|
| Treatment (obinutuzumab, glofitamab, pirtobrutinib) | EXPERIMENTAL | Participants receive obinutuzumab IV on days 1 and 2 of cycle 1 for a total of 2 doses. Participants receive glofitamab IV on days 8 and 15 of cycle 1 and day 1 of remaining cycles. Cycles repeat every 21 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Participants receive pirtobrutinib PO once a day (QD) on days 1-21. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity up to Cycle 30, Day 22. Participants also undergo FDG-PET/CT at screening, after every 4 cycles through cycle 13 and then after every 6 cycles. Participants will undergo a bone marrow biopsy and aspiration at cycle 13 and blood sample collection throughout study and a tissue biopsy at relapse or progression. |
