Background. Novel agents immune checkpoint inhibitors fundamentally changed the prognosis for life in patients with metastatic and/or inoperable melanoma. The development, studies, and approval of a new original PD1 inhibitor in Russia in 2020 prompted the professional community to conduct a prospective observational study in the Russian Federation to assess the real-world efficacy and safety of prolgolimab, as real-world patients differ from the refined population in clinical trials. Aim. To evaluate the real-world efficacy and safety of prolgolimab in patients with metastatic and/or inoperable melanoma. Materials and methods. From October 2020 to October 2022, the study enrolled 700 patients with metastatic and/or inoperable melanoma receiving prolgolimab in real clinical settings in oncological institutions of various levels in the Russian Federation. The main inclusion criteria were: pathology-confirmed diagnosis of melanoma, metastatic and/or inoperable type, use of prolgolimab outside of clinical trials, and signed informed consent by the patient. Objective response rate (ORR) was considered the main criterion for evaluating the efficacy of therapy, and the safety criterion was the incidence of grade 34 adverse events. Statistical analysis was performed using the SPSS 20.0 software package. Results. The ORR for patients with skin melanoma treated with prolgolimab in the first line therapy (n= 207/337) was 48.3% (n=100), the disease stabilization was reported in 30.4% (n=63), and progression in 21.3% (n=44) of patients. There were no significant differences in response to therapy between patients with/withoutBRAFmutation, although ORR was higher in patients withBRAFmutation: the ORR for patients withBRAFmutation was 57.9% (n=33), and forBRAFnon-mutated patients, 44.4% (n=52;p=0.222). At a median follow-up of 5 months, the median PFS was 10 months (95% confidence interval 7.3512.64). The incidence of grade 34 treatment-related adverse events according to CTCAE 5.0 was 2% (n=12), and 12% (n=82) for grade 12 adverse events. Conclusion. The results confirm the high efficacy and satisfactory tolerability of prolgolimab in patients with metastatic and/or inoperable melanoma in real-world settings. There were no significant differences in ORR between patients with or withoutBRAFmutation.
