Phase I/II clinical trial of a melanoma vaccine targeting shared non-mutated antigens and a shared mutated BRAF neoantigen with an agonistic CD40 antibody (CDX-1140) plus TLR3 agonist (poly-ICLC)

Background
For patients with high-risk melanoma who are unresponsive or intolerant to immune checkpoint inhibitors, cancer vaccines may provide benefit with a favorable toxicity profile. CD4+ T cells provide essential help to dendritic cells (DCs) for…

Clinical and translational results from a phase 1 trial of gemcitabine/nab-paclitaxel with nivolumab/ipilimumab or hydroxychloroquine/ipilimumab in untreated metastatic pancreatic adenocarcinoma

Background
Patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) often respond to cytotoxic therapy, but early disease progression is typical. Responses to immunotherapy alone are rare. Recent advances in chemoimmunotherapy combinations of…

Caninized PD-1 monoclonal antibody in oral malignant melanoma: efficacy and exploratory biomarker analysis

Background
Canine oral malignant melanoma (OMM) is a highly aggressive tumor, with several available treatment options, though few achieve durable response or complete remission. Because of its biological similarity to human mucosal melanoma, canine O…

Primary and secondary pseudo-stability and progression after atezolizumab with and without bevacizumab

Background
Atypical tumor response patterns associated with immunotherapies pose significant challenges for assessing treatment response and clinical decision-making. We characterized the epidemiology, clinical impact, and molecular determinants of ps…

Neoadjuvant lenvatinib plus pembrolizumab in Merkel cell carcinoma: an investigator-initiated, open-label phase II trial

Background
Given the success of checkpoint inhibitor therapy in the advanced Merkel cell carcinoma (MCC) setting, there is interest in exploring immunotherapy as a neoadjuvant approach. We report the primary results of a neoadjuvant study of lenvatini…

Decoding adipocyte heterogeneity through single-nucleus transcriptomics unveils subtype-specific adipocytes orchestrate immunosuppressive niches in breast cancer

Background
While adipose tissue constitutes a substantial proportion of breast composition, the functional characteristics and pathological relevance of the adipocyte microenvironment in breast carcinogenesis remain undercharacterized. This study empl…

Botensilimab (Fc-enhanced anti-CTLA-4 antibody) plus balstilimab (anti-PD-1 antibody) in patients with treatment-refractory ovarian cancer

Background
Patients with platinum-resistant/refractory ovarian cancer (PROC) experience suboptimal outcomes, highlighting an immediate need for novel therapies. This phase 1b study investigated the safety and efficacy of botensilimab (BOT), a fragment…

Interpretable multimodal radiopathomics model predicting pathological complete response to neoadjuvant chemoimmunotherapy in esophageal squamous cell carcinoma

Background
Accurate preoperative prediction of pathological complete response (pCR) following neoadjuvant chemoimmunotherapy (nCIT) could help individualize treatment for patients with esophageal squamous cell carcinoma (ESCC). This study aimed to dev…

Phase 1 study evaluating the safety, preliminary efficacy, and pharmacodynamics of recombinant interleukin-15 in combination with nivolumab and ipilimumab in patients with refractory cancers

Purpose
Combinations of immune checkpoint inhibitors and cytokine therapies have shown promise in cancer immunotherapy. We aimed to evaluate the safety, tolerability, and preliminary efficacy of recombinant human interleukin-15 (rhIL-15) in combinatio…

Patterns of immune-related adverse events and treatment responses in adolescents and young adults with melanoma during initial and rechallenge immune checkpoint inhibitor therapy

Background
Immune checkpoint inhibitors (ICIs) are increasingly used in adolescents and young adults (AYAs) with cancer; however, data on treatment response, the frequency and pattern of immune-related adverse events (irAEs), and the feasibility of IC…
