Summary: In this study, peri-tumor administration of hydrogel-encapsulated anti-CTLA-4 was found to specifically target tumor-draining lymph nodes, and the inclusion of hyaluronidase enhanced this targeting effect. These findings provide a theoretical basis for further optimizing immunotherapy.

Summary: CTLA-4 and PD-1 are immune checkpoint molecules that are targets of antibody immunotherapies for malignant melanoma. Combination therapy with immune checkpoint inhibitors may have better outcomes compared to monotherapy in certain patient groups, but also presents challenges and increased rates of adverse events.

Summary: Immune checkpoint inhibitors (ICIs) such as CTLA-4 and PD-1-blocking antibodies have significant effects on tumor immune cell infiltration. In this study, we analyzed molecular datasets from 514 patients with advanced melanoma to explore the features of anti-PD-1 response. We found that prior anti-CTLA-4 therapy is associated with genomic and transcriptomic differences in anti-PD-1 responders, suggesting that the tumor microenvironment plays a role in predicting the response to PD-1 blockade therapy.

Summary: Anti-CTLA-4 antibodies have limited long-term benefit in tumor regression. We engineered a nonantagonistic CTLA-4 binding domain and found that both CTLA-4 antagonism and intratumoral Treg depletion are needed for maximum efficacy in anti-CTLA-4 therapy.

Summary: The resistance to immune checkpoint blockade (ICB) therapy in non-small cell lung cancer (NSCLC) is associated with infiltrating monocytes, and controlling the differentiation process of monocytes can enhance the therapeutic potential of ICB.

Summary: This study demonstrates a highly effective and safe strategy to target CTLA-4 using a vectorized alpha CTLA-4 with strong Treg-depleting and checkpoint-blocking properties. This approach shows promising results in enhancing anti-tumor immunity.

Summary: This study demonstrates the production of anti-CTLA-4 2C8 antibody using Nicotiana benthamiana as a plant expression system and validates its efficacy in inhibiting tumor growth through animal experiments. It highlights the potential of plant platforms in cancer immunotherapy.

Summary: The study found that the combination of radiotherapy (RT) with immune checkpoint inhibitors (ICIs) did not result in a significant survival benefit for patients with mucosal melanoma (MUM), although it may help improve local tumor control and relieve local symptoms.

Summary: Treatment with IPI + NY-ESO-1 vaccines enhanced T cell and antibody responses in patients. Patients with best clinical responses had broader antibody responses and increased T cell densities.

Summary: In a study of advanced mucosal melanoma patients in Japan, it was found that there was no significant difference in efficacy between PD1 and PD1 + CTLA4, but the latter had a higher incidence of immune-related adverse events.

Summary: Acral melanoma is a rare subtype with poor prognosis, and there is a lack of prospective clinical trial evidence on the efficacy of checkpoint inhibitors in this population. The study found that initial anti-PD-1/ipilimumab combination had a significantly higher ORR compared to anti-PD-1 alone, but this benefit did not translate to improved OS in this retrospective cohort. Primary site did not impact treatment outcomes.

Summary: Multiparametric MRI showed potential for early detection of successful response to immune checkpoint inhibitors in metastatic melanoma. Significant intertumoral heterogeneity in tumor growth kinetics and early detection of tumor cell death or loss were observed. Tumor heterogeneity measured by apparent diffusional kurtosis was consistently higher in non-responding lesions compared to responding lesions throughout the first 12 weeks of treatment.

Summary: While immune checkpoint inhibitors targeting CTLA-4 and PD-1 have improved outcomes for many patients with metastatic melanoma, there remains a subset of patients who do not respond. This study identified two distinct groups of non-responders based on their gene expression profiles, highlighting the importance of a personalized approach for identifying effective treatments for anti-PD-1 resistant patients.
