Study CC-95251-ST-001 is an open-label, Phase 1, dose escalation (Part A) and expansion (Part B), first-in-human clinical study of CC-95251 in subjects with advanced solid cancers. The dose escalation part (Part A) of the study will be conducted in two stages. Stage 1 will evaluate the safety and tolerability of escalating doses of CC-95251, administered IV, to determine the maximum tolerated dose (MTD), non-tolerated dose (NTD), and/or recommended Phase 2 dose (RP2D) of CC-95251. Stage 2 will evaluate the safety and tolerability of escalating doses of CC-95251 in combination with weekly cetuximab, both administered IV, to determine the MTD, NTD, and/or RP2D of CC-95251 plus cetuximab.
