Personalized cancer immunotherapy has gained traction with the development of neoantigen-targeting vaccines, which have shown promise in generating robust immune responses. A study demonstrated that a synthetic long peptide vaccine, when combined with Montanide, poly-ICLC, and ipilimumab, elicited significant T cell responses in melanoma patients, with 9 out of 10 patients generating responses against multiple neoepitopes (ref: Blass doi.org/10.1016/j.cell.2025.06.019/). In another investigation, the role of TIM3 in micrometastatic breast cancer was explored, revealing its potential as a therapeutic target by identifying vulnerabilities in tumor-immune interactions during early metastatic stages (ref: Rozalén doi.org/10.1016/j.ccell.2025.06.015/). Furthermore, alterations in KEAP1 and STK11/LKB1 were found to enhance the vulnerability of KRAS mutant non-small cell lung cancer to ATR inhibitors, suggesting a new avenue for targeted therapies in this aggressive cancer subtype (ref: Galan-Cobo doi.org/10.1016/j.ccell.2025.06.011/). The Cancer Immunology Data Engine (CIDE) was developed to facilitate the discovery of potential immunotherapies, highlighting secreted AOAH as a promising candidate (ref: Gong doi.org/10.1016/j.cell.2025.07.004/). Additionally, a phase III trial of daromun, an immunocytokine therapy, showed promising results in stage III melanoma, indicating the potential of targeted immunotherapy in neoadjuvant settings (ref: Kähler doi.org/10.1016/j.annonc.2025.06.014/).
