Neoadjuvant anlotinib/sintilimab plus chemotherapy in triple-negative breast cancer (NeoSACT): Phase 2 trial.
Tumor angiogenesis contributes to immune evasion, and vascular normalization enhances immunotherapy response by reshaping the tumor microenvironment. This phase 2 trial evaluates neoadjuvant anlotinib (antiangiogenic), sintilimab (programmed cell death protein 1 [PD-1] inhibitor), and chemotherapy in 29 patients with stage II-III triple-negative breast cancer (TNBC). The primary endpoint, pathological complete response (pCR), is achieved in 69.0% (95% confidence interval [CI]: 49.0%-85.0%), with an 86.2% minimal residual disease (residual cancer burden [RCB] 0 + 1) rate. Notably, programmed death-ligand 1 (PD-L1)-negative patients achieve a 75.0% pCR rate, comparable to PD-L1-positive patients (64.7%). The 2-year event-free survival (EFS) is 92.4%, with 100% EFS in pCR patients. Grade 3/4 adverse events occur in 31.0% of patients, primarily rash and hematologic toxicities. These results demonstrate that combining antiangiogenic therapy with immunotherapy and chemotherapy enhances treatment efficacy, potentially overcoming PD-L1 limitations, and supports further investigation in high-risk TNBC. This trial was registered at ClinicalTrials.gov (NCT04877821).

期刊介绍:
Cell Reports Medicine is an esteemed open-access journal by Cell Press that publishes groundbreaking research in translational and clinical biomedical sciences, influencing human health and medicine.
Our journal ensures wide visibility and accessibility, reaching scientists and clinicians across various medical disciplines. We publish original research that spans from intriguing human biology concepts to all aspects of clinical work. We encourage submissions that introduce innovative ideas, forging new paths in clinical research and practice. We also welcome studies that provide vital information, enhancing our understanding of current standards of care in diagnosis, treatment, and prognosis. This encompasses translational studies, clinical trials (including long-term follow-ups), genomics, biomarker discovery, and technological advancements that contribute to diagnostics, treatment, and healthcare. Additionally, studies based on vertebrate model organisms are within the scope of the journal, as long as they directly relate to human health and disease.
