Cell Phone To The Death And ThereAfter

In the extrinsic pathway (left), apoptosis is triggered by binding of a ligand to a cell surface death receptor with subsequent formation of a cytoplasmic death-inducing signaling complex that activates an initiator caspase (e.g., caspase-8). The intrinsic pathway (right) of apoptosis is triggered by DNA damage or various cell stressors, especially those that result in permeabilization of the mitochondrial outer membrane, and leads to formation of the caspase-activating complex or apoptosome. The initiator caspase in the intrinsic pathway is usually caspase-9. In both the extrinsic and the intrinsic pathways, initiator caspases activate effector (executioner) caspases, resulting in cell death with the characteristic morphologic features of apoptosis (shown at bottom).

The virus causes hepatocellular death, typically by oncotic necrosis, but sometimes by apoptosis. Note coagulative necrosis (lower left) with lytic necrosis (center left) and individual cells with features of apoptosis (arrows). H&E stain.

Higher dose levels 15 mg/kg and/or 20 mg/kg may also be explored. Dostarlimab will be administered intravenously (IV) on Day 1 and Day 15 of each cycle; cycle length is 28 days. Cohorts will be enrolled sequentially and will initially follow a 3+3 design. Biological: DostarlimabDostarlimab (160 mg, 20 mg/mL; or 500 mg, 50 mg/mL) is a humanized monoclonal antibody that binds with high affinity to PD-1 resulting in inhibition of binding to programmed death receptor ligands 1 and 2 (PD-L1 and PD-L2). Dostarlimab will be administered via a 30 minute IV infusion on Day 1 and Day 15 of each cycle in Part 1. For additional patients enrolled specifically to better characterize the PK/PDy profile in Part 1, dostarlimab administration during Cycle 1 will only occur on Day 1 with the second dose administered on Cycle 2/Day 1 and Q2W thereafter. For Part 2A and 2B, dostarlimab will be administered on Day 1 of each treatment cycle. Cycle duration for Q3W dosing is 21 days and Q6W dosing is 42 days. Experimental: Part 2A: Participants receiving dostarlimabIn Part 2A, participants will receive fixed dose of 500 mg administered Q3W or 1000 mg administered Q6W dose on Day 1 of each cycle. Cycle duration for Q3W dosing is 21 days and Q6W dosing is 42 days. Cohorts will enroll participants with advanced solid tumor using a modified 6+6 design and will follow a 6+6 design.

Experimental: Part 2B: Cohort A1 dMMR/MSI-H endometrial cancerPart 2B: Cohort A1 will include participants with mismatch repair deficient microsatellite instability high (dMMR/MSI-H) endometrial cancer who have progressed on or after platinum doublet therapy. These participants will receive dostarlimab 500 mg for Q3W for the first 4 cycles followed by 1000 mg Q6W for all subsequent cycles. Participants have received no more than 2 lines of anti-cancer therapy for recurrent or advanced (Stage >= IIIB) disease.
