Resistance to anti-PD-1 immunotherapy for stage III and IV melanoma: a global chart review study

Background
Anti-programmed cell death protein 1 (PD-1) immunotherapy has revolutionized the treatment of stage III and IV melanoma. Real-world data on its resistance is needed to facilitate the development of combinatorial approaches to overcome anti-…

Oncolytic virotherapy potentiates chemo-PD-1 immunotherapy by engaging chemo-resistant bystander CD8+ T cells

Background
The efficacy of combined chemotherapy and programmed cell death protein-1 (PD-1) immune checkpoint blockade (ICB) is constrained by the collateral cytotoxicity of chemotherapy toward proliferating tumor-specific CD8+ T (TTST) cells, a popul…

Antibody therapeutics with high affinity for Fc{gamma}Rs exacerbate anaphylaxis via Fc{gamma}R-mediated capture by tumor-associated myeloid cells

Background
Antibody therapeutics have revolutionized cancer treatment, but their use is increasingly associated with adverse events. Among these, anaphylaxis is particularly concerning due to its severity and unpredictability. Our previous studies dem…

Androgen deprivation, androgen receptor-targeted vaccination, and nivolumab in patients with high-risk localized prostate cancer

Background
In murine studies, we demonstrated that a DNA vaccine encoding the androgen receptor (pTVG-AR) given prior to androgen deprivation elicited prostate tumor-infiltrating lymphocytes and an antitumor response. The current trial evaluated this …

Priorities for local immunotherapy research and drug development

Local immunotherapy comprises broad classes of therapeutics that aim to trigger a robust “in situ” immune response that can ultimately generate systemic antitumor immunity. These agents are appealing as resistance to standard immune checkpoint inhibit…

Influence of body composition on the efficacy of nivolumab plus ipilimumab for metastatic clear cell renal cell carcinoma

Background
Immune checkpoint inhibitor therapy (ICI) with nivolumab+ipilimumab is a first-line (1L) standard for metastatic clear cell renal cell carcinoma (ccRCC), yet outcomes remain heterogeneous. Increasing evidence suggests that host factors infl…

Effects of oncolytic immunotherapy with RP1 (vusolimogene oderparepvec) on immune cells mediate responsiveness to anti-PD-1 via STING-mediated interferon signaling

Background
Antitumor immune responses induced by oncolytic immunotherapy (OI) are often followed by upregulation of programmed death-ligand 1 (PD-L1). As such, the combination of OI with blockade of the programmed cell death protein-1 (PD-1)/PD-L1 axi…

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…

Where is the data? Delayed and chronic irAE surveillance and management after cessation of ICIs: expert insights from SITC on survivorship care and the need for long-term data

Immune checkpoint inhibitors (ICIs) have revolutionized cancer therapy, offering durable responses and prolonged survival. However, these therapies also present unique challenges, particularly with the onset of immune-related adverse events (irAEs), w…
