This retrospective observational study used data from Flatiron Health’s (NY, USA) advanced melanoma database to determine outcomes of retreatment with anti-PD-1 monotherapy for melanoma. The study concluded that patients who had received a second course of anti-PD-1 monotherapy demonstrated 100% survival at a year post-therapy administration, and had a median overall survival of 30 months.

Aims: To determine outcomes of retreatment with anti-PD-1 monotherapy for melanoma.
Methods: This retrospective study included adults with unresectable cutaneous melanoma who achieved stable disease (SD) or better after anti-PD-1 monotherapy and were retreated with anti-PD-1 monotherapy after ≥90-day gap. We determined overall survival (OS) and real-world tumor response (rwTR).
Results: For 21 eligible patients, from retreatment initiation, median follow-up was 14.4 months (range, 2.6-34.5); median OS was 30 months (95% CI, 14.4-not reached); 1-year survival was 100% (95% CI, 100-100%); 2-year survival was 83% (48-96%). Of 16 patients with recorded best rwTR, 10 (63%) responded (complete/partial response); 3 achieved SD; 3 had progressive disease.
Conclusions: Patients with advanced melanoma achieving SD/better after first-course anti-PD-1 monotherapy may benefit from retreatment.Read the full paper here
