The safety profile of cemiplimab was comparable with other anti-PD-1 agents. Addition of hfRT and/or CPA did not appear to increase grade ≥3 irAEs, suggesting that cemiplimab can be safely administered with hfRT and/or CPA. Cemiplimab exhibited encouraging antitumor activity with 2 complete responses and 7 partial responses observed; responses were also durable.
