Patients exhibit short survival periods, with median overall survival ranging from 5.1 to 18 months, representing a significant unmet clinical need. Sacituzumab govitecan has been evaluated in multiple clinical trials including OptiTROP-Breast01, KL264-01, OptiTROP-Lung01, OptiTROP-Lung03, and SKB264-Ⅱ-06. Current results consistently indicate promising efficacy of Sacituzumab govitecan in lung cancer, breast cancer, and cervical cancer. Notably, data presented at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting revealed that TROP2 is highly expressed in neuroendocrine tumors, and its expression is significantly associated with poor prognosis. This suggests TROP2-directed antibody-drug conjugates (ADCs) may demonstrate promising therapeutic potential in NENs.\n\nResearch Objective:To evaluate the efficacy of Sacituzumab govitecan in patients with advanced extrapulmonary neuroendocrine neoplasms who have progressed on standard therapies.",[41],"Neuroendocrine Neoplasms (Tumours)","NOT_YET_RECRUITING","2025-07-20",{"date":45,"type":46},"2025-07-22","ACTUAL",{"date":43,"type":35},{"date":49,"type":35},"2028-07-20",{"name":5,"class":6}]
