Meanwhile, MT3-KN035 conjugated multiple aldoxorubicin (hereafter, these conjugates are referred to as MT3-KN035-DOX) via an acidic cleavable linker; MT3-KN035-DOXHigh induced tumor apoptosis and exhibited significant antitumor efficacy via facilitating immune cell infiltrations. This work provides a novel therapeutic strategy via nanobody-mediated target engagement and internalization that achieves synergistic therapeutic efficacy between chemotherapy and immune checkpoint blockade therapy.

We highlight that TGF-β-driven immune suppression and immune exclusion are often spatially organized within stromal niches, vary across indications, and are not always the dominant barrier even when PD-L1 is expressed. SHR-1701's approval provides proof of principle in a defined context and supports mechanism-aligned development using biomarker-driven selection, rational combinations and sequencing, and pharmacodynamic endpoints that directly test these assumptions.

We present the case of a 60-year-old non-smoking woman previously treated for luminal B human epidermal growth factor receptor 2 (HER2)-positive invasive breast carcinoma with surgery, AC60 chemotherapy, trastuzumab, breast radiotherapy, and hormone therapy at the Mohammed VI Oncology Center in Casablanca, Morocco. The patient received neoadjuvant vinorelbine-cisplatin chemotherapy followed by volumetric modulated arc therapy (VMAT) thoracic radiotherapy at 66 Gy, achieving clinical and radiological stabilization. This case highlights the occurrence of a second driver-negative primary lung adenocarcinoma in a non-smoker and underscores the importance of integrated histopathological, immunohisto chemical, and targeted molecular evaluation in distinguishing primary tumors from metastases, as well as the potential role of post-therapeutic carcinogenesis.

We demonstrate that GSK3368715, a small-molecule inhibitor of PRMT1, downregulates the protein levels of the histone lysine methyltransferase SUV39H1 by enhancing its ubiquitination...Importantly, the combination of dual inhibition with anti-PD-L1 antibody enhances the responsiveness of breast cancer to immunotherapy. Taken together, our findings indicate that co-targeting PRMT1 and SUV39H1 represents a promising therapeutic strategy for breast cancer.

Toripalimab combined with chemotherapy (Toripa-chemo) showed the greatest OS benefit in the overall population (HR = 0.58, 95% CI: 0.38-0.87). Atezolizumab combined with Entinostat and chemotherapy (Atezo-Entino-chemo) showed a trend toward improved OS (HR = 0.49, 95% CI: 0.22-1.12) and ORR (OR = 5.14, 95% CI: 0.70-37.94)...Toripa-chemo and Pembro-chemo demonstrate a balanced profile of efficacy and safety, suggesting that they may be suitable options for first-line treatment of mTNBC. Among these, Toripa-chemo may be considered a preferred first-line regimen for PD-L1 positive patients. https://www.crd.york.ac.uk/prospero/, identifier ID: CRD420251138714.

These findings demonstrate that mTORi with everolimus reverses multiple mechanisms of immune resistance in TP53 -mutant HNSCC by promoting immune cell recruitment, suppressing immunosuppressive pathways, and enhancing anti-tumor T cell activity. Collectively, these results support mTORi as a mechanistically rational strategy for reprogramming immune resistance in TP53 -mutant HNSCC and provide a strong preclinical rationale for combining everolimus with immune therapy in patients who are likely to fail immunotherapy.

Safety and efficacy were consistent with results from IMpassion130, which enrolled a more selected population.
