To determine outcomes of retreatment with anti-PD-1 monotherapy for melanoma. 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 and real-world tumor response. For 21 eligible patients, from retreatment initiation, median follow-up was 14.4 months (range, 2.6-34.5); median overall survival was 30.0 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 real-world tumor response, ten (63%) responded (complete/partial response); three achieved SD; three had progressive disease. Patients with advanced melanoma achieving SD/better after first-course anti-PD-1 monotherapy may benefit from retreatment.

Background: The distribution of adverse events (AEs) triggered by immune checkpoint inhibitors (ICIs) across different cancer types has never been demonstrated.

Methods: Randomised controlled trials exclusively assessing ICI monotherapy in cohorts of over 100 patients were considered. Our primary outcome was a comprehensive summary of the distribution of all-grade treatment-related adverse events (TRAEs) as well as serious TRAEs (CTCAE grade 3 or higher) across different malignancies.

Neoadjuvant or perioperative immunotherapy for resectable melanoma: The need for biomarkers.

Eur J Cancer

January 2025

National Center for Cancer Immune Therapy, Department of Oncology, Copenhagen University Hospital, Herlev, Denmark. Electronic address:

Groundbreaking studies have reshaped the treatment landscape for patients with resectable stage ≥IIIB melanoma by demonstrating the benefits of neoadjuvant therapy. Data from the NADINA and SWOG S1801 trials reveal substantial improvements in event-free survival compared to adjuvant therapy alone. These studies employed distinct neoadjuvant immunotherapy approaches - ipilimumab plus nivolumab in NADINA and anti-PD-1 monotherapy in SWOG S1801 - highlighting potential differences in efficacy and toxicity.

The treatment landscape for advanced melanoma has transformed significantly with the advent of BRAF and MEK inhibitors (BRAF/MEKi) targeting V600 mutations, as well as immune checkpoint inhibitors (ICI) like anti-PD-1 monotherapy or its combinations with anti-CTLA-4 or anti-LAG-3. Despite that, many patients still do not benefit from these treatments at all or develop resistance mechanisms. Therefore, prognostic and predictive biomarkers are needed to identify patients who should switch or escalate their treatment strategies or initiate an intensive follow-up.

HMGB1 assists the predictive value of tumor PD-L1 expression for the efficacy of anti-PD-1/PD-L1 antibody in NSCLC.

Department of Molecular and Internal Medicine, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima, Japan.

Background: The expression of anti-programmed cell death ligand-1 (PD-L1) in tumors is widely used as a biomarker to predict the therapeutic efficacy of anti-programmed cell death-1(PD-1)/PD-L1 antibodies. However, the predictive accuracy of this method is limited. High-mobility group box 1 (HMGB1) is known to modulate cancer immunity.

Co-blocking TIGIT and PVRIG using a novel bispecific antibody enhances anti-tumor immunity.

Mol Cancer Ther

January 2025

Jiangsu Hengrui Pharmaceutical Co. Ltd, Shanghai, China.

TIGIT and PVRIG are immune checkpoints co-expressed on activated T and NK cells, contributing to tumor immune evasion. Simultaneous blockade of these pathways may enhance therapeutic efficacy, positioning them as promising dual targets for cancer immunotherapy. This study aimed to develop a bispecific antibody (BsAb) to co-target TIGIT and PVRIG.
