Efficacy and safety of PD‐1 monoclonal antibody combined with interferon‐alpha 1b and anlotinib hydrochloride as the second‐line therapy in patients with unresectable advanced melanoma: A retrospective study

Immune-checkpoint inhibitors are now used more commonly in combination than monotherapy as the first-line choice in patients with unresectable advanced melanoma. Nevertheless, for cases that progressed after the initial combination therapy, the subsequent regimen option can be very difficult. Herein, we reported the efficacy and safety of a triple combination regimen in Chinese unresectable advanced melanoma patients who had poor responses to the first-line immune therapy.
