这是一项早期 I 期注册临床试验,评估细胞治疗用于肉瘤的安全性、可行性及初步疗效。当前状态:进行中(不再招募)。计划入组 1 例。试验地点:其他 · 卡尔加里(共 1 个中心)。登记号:NCT06813417。
仅女性
纳入标准: • 患者须提供知情同意。 • 器官功能充分,定义为肌酐清除率>30 mL/min 且左室射血分数>45%。 排除标准: • 任何活动性未控制感染。 • 妊娠或哺乳。 • 首次淋巴细胞清除化疗前21个日历日内接受过抗癌治疗。若接受过抗癌治疗,须在开始治疗前充分恢复相关毒性和/或并发症;是否恢复充分由合格研究者/共同研究者判断。
Inclusion Criteria: * The patient must provide informed consent * Adequate organ function, defined as creatinine clearance \>30 ml/min and LVEF \>45% Exclusion Criteria: * Any active uncontrolled infection * Pregnancy or nursing * Anti-cancer therapy within 21 calendar days prior to the first dose of lymphodepleting chemotherapy. If subject has received anti-cancer therapy, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy as per the discretion of the Qualified Investigator/Co-Investigator

主要终点:Treatment Response · The overall response assessment considers the response of the target and non-target lesions and development of new lesions. Response Classification of Target Lesions, CNS lesions and Non-Target Lesions * Complete response (CR): * Partial response (PR): * Progressive disease (PD): * Stable disease (SD): · Diagnostic imaging (CT and/or MRI) will be performed at baseline (pre-treatment) and then subsequently at 4-6 weeks after GCAR1 infusion, and at 3 months, 6 months, 9 months and 1 year after last infusion to evaluate response to therapy.
本研究采用患者内两次剂量递增。患者接受两次冷冻保存的自体 GCAR1 静脉输注,两次输注至少间隔3个月(±30天),每次输注前均接受标准淋巴细胞清除化疗:氟达拉滨40 mg/m²/日、共3天;环磷酰胺600 mg/m²/日、共2天。第1次剂量为5.0×10⁶ CAR 阳性 T 细胞/kg体重;第2次剂量为2.5×10⁷ CAR 阳性 T 细胞/kg体重。
这项单患者研究旨在评估 GCAR1 对复发且对常规治疗无反应、GPNMB 表面表达阳性的肺泡软组织肉瘤(ASPS)进行再治疗的安全性和疗效。
A single patient study to determine whether GCAR1 is safe and effective for re-treatment of alveolar soft part sarcoma (ASPS) with GPNMB surface expression that has relapsed and is not responding to usual treatment.
