Experimental
Arm A (pembrolizumab, TTI-621)
Arm B (pembrolizumab, TTI-622)
Patients receive pembrolizumab IV over 30 minutes on day 1 of each cycle and TTI-621 IV over 60-120 minutes on day 1 of each cycle. Treatment repeats every 21 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo PET/CT scans or CT scans of the chest, abdomen, and pelvis prior to cycle 3 and every 4 cycles thereafter. If no disease progression after cycle 12, patients then receive pembrolizumab IV over 30 minutes on days 1 of each cycle and TTI-621 IV over 60-120 minutes on day 1 of each cycle. Treatment repeats every 21 days for up to 23 cycles in the absence of disease progression or unacceptable toxicity.
Patients receive pembrolizumab IV over 30 minutes on day 1 of each cycle and TTI-622 IV over 60-90 minutes on day 1 of each cycle. Treatment repeats every 21 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo PET/CT scans or CT scans of the chest, abdomen, and pelvis prior to cycle 3 and every 4 cycles thereafter. If no disease progression after cycle 12, patients then receive pembrolizumab IV over 30 minutes on days 1 of each cycle and TTI-622 IV over 60-90 minutes on day 1 of each cycle.
