简要总结
This is a multicenter, prospective, open-label Phase II clinical study designed to evaluate the efficacy and safety of sacituzumab govitecan monotherapy in patients with locally advanced or metastatic pancreatic ductal adenocarcinoma who have failed at least one prior line of therapy, and to explore the potential correlation between baseline tumor tissue TROP-2 expression and treatment efficacy. The study plans to enroll 30 eligible subjects, who will receive sacituzumab govitecan at 5 mg/kg via intravenous infusion every 2 weeks as one treatment cycle, until disease progression or intolerable toxicity occurs. The primary endpoint is Objective Response Rate (ORR); secondary endpoints include Progression-Free Survival (PFS), Overall Survival (OS), Disease Control Rate (DCR), Duration of Response (DOR), and the incidence and severity of Treatment-Related Adverse Events (TRAEs).

- •Presence of untreated or unstable spinal cord compression
- •High risk of gastrointestinal or intra-abdominal bleeding
- •Prior treatment with TROP2-targeted agents or antibody-drug conjugates (ADCs)
- •Requirement for strong CYP3A4 inhibitors or inducers within 2 weeks prior to the first dose, or inability to avoid their use during the study
- •History of severe dry eye syndrome, meibomian gland disease, or other corneal disorders that may impair corneal healing
- •Major surgery within 28 days prior to the first dose (excluding palliative procedures), or receipt of curative radiotherapy within 3 months
- •Presence of other malignancies within 3 years prior to the first treatment (except for certain definitively treated cancers)
- •Uncontrolled severe systemic diseases such as cardiovascular or cerebrovascular disease, diabetes mellitus, or hypertension
- •History of interstitial lung disease or non-infectious pneumonitis, or current related lesions
- •Presence of severe underlying pulmonary disease, autoimmune disease, or prior total pneumonectomy
- •Active chronic inflammatory bowel disease, gastrointestinal obstruction, or other severe gastrointestinal disorders
- •Tumor invasion of critical organs or vessels with associated symptoms, or risk of fistula formation
- •Toxicities from prior antitumor therapy not recovered to ≤ Grade 1 (except for low-risk toxicities)
- •Active hepatitis B, hepatitis C, HIV infection, or active syphilis
- •Known allergy to the investigational drug or its components, or history of severe hypersensitivity to other biologic agents
- •Severe infection within 4 weeks prior to dosing, or active infection requiring systemic therapy within 2 weeks
- •Receipt of non-specific immunomodulatory therapy or antitumor traditional Chinese medicine within 2 weeks prior to dosing
- •Receipt of live vaccines within 30 days prior to dosing or planned during the study period
