Integrating interferon gamma receptor pathways, antigenicity, and immune contexture as predictors of immunotherapeutic strategies for mucosal melanomas

Background
Mucosal melanomas (MM) arise from mucosal melanocytes at various anatomical sites. These tumors are rare, highly aggressive, and often associated with poor outcomes. Current treatments, including immune checkpoint inhibitors, show limited e…

Antibiotic-associated dysbiosis and bispecific antibody outcomes in multiple myeloma

Background
The gut microbiota plays a critical role in regulating immune homeostasis and modulating responses to cancer immunotherapies. However, the impact of antibiotic-induced dysbiosis in patients with multiple myeloma (MM) treated with bispecific…

Prospective study of patients with immune checkpoint inhibitor-induced hepatitis; characterization of liver injury, outcome of therapy, and management of steroid-unresponsive and steroid-dependent hepatitis

Background
Immune-related hepatitis (ir-hepatitis) ranks among the most frequent adverse events of immune checkpoint inhibitors (ICIs). Limited knowledge exists regarding the incidence, characteristics, and treatment of patients having an inadequate r…

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…
