Primary resistance to PD-1 blockade therapy can be reversed in some patients with combination of CTLA-4 and PD-1 blockade

19 October 2023

In this randomized phase 2 trial, blockade of cytotoxic T-lymphocyte protein 4 (CTLA-4) with continuation of programmed death protein 1 (PD-1) blockade in patients with metastatic melanoma who had received front-line anti-PD-1 or therapy against programmed cell death 1 ligand 1 and whose tumors progressed was tested in comparison with CTLA-4 blockade alone. The study concludes that primary resistance to PD-1 blockade therapy can be reversed in some patients with the combination of CTLA-4 and PD-1 blockade.

Similar local recurrence and survival in patients with T1 radial growth phase melanoma on head and neck treated with 5 or 10 mm margins

19 October 2023

The objective of this recent study was to compare outcomes of wide (10 mm margins) versus narrow (5 mm margins) excisions in patients with radial growth phase T1 melanoma (invasive melanomas with Breslow thickness ≤1 mm) on head-and-neck including face. Authors conclude that narrower excision margins are not associated with worse overall survival or increased local recurrence compared to wider margins, and may be safely applied to such lesions, although caution may be required in the presence of lentigo maligna melanoma.

Extended follow-up of chronic immune-related adverse events following adjuvant anti-PD-1 therapy for high-risk resected melanoma

19 October 2023

According to this recent cohort study of 318 patients with advanced or metastatic melanoma who received adjuvant anti–PD-1, chronic immune-related adverse events were common, affected diverse organ systems, and often persisted with long-term follow-up requiring steroids and additional management. Findings highlight the likelihood of persistent toxic effects when considering adjuvant therapies and need for long-term monitoring and management.

PIVOT IO 001 study​: No additional clinical benefit of BEMPEG plus NIVO combination therapy versus NIVO monotherapy for previously untreated unresectable or metastatic melanoma

17 October 2023

According to the PIVOT IO 001 study, Bempegaldesleukin (BEMPEG) plus nivolumab (NIVO) combination therapy provided no additional clinical benefit compared with NIVO monotherapy in patients with previously untreated unresectable or metastatic melanoma. A higher incidence of treatment-related adverse events with a lack of added efficacy was noted with BEMPEG plus NIVO versus NIVO alone.
