Experimental Treatment

Group I: Treatment (CBM588 capsules, nivolumab, ipilimumab)Experimental Treatment7 Interventions

Patients receive CBM588 PO BID on days 1-21, nivolumab IV over 30 minutes and ipilimumab IV over 30 minutes on day 1 of each cycle. Cycles repeat every 21 days for 4 cycles. Patients then receive CBM588 PO BID on days 1-28 and nivolumab IV on day 1. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
