JRCT ID: jRCT2033200431

Registered date:18/03/2021

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: Patients with GPC3-expressing advanced ovarian clear cell carcinoma with peritoneal dissemination
• Date of first enrollment: 10/05/2021
• Target sample size: 18
• Study type: Interventional
• Intervention(s): As iCAR-ILC-N101, 1 x 10^6 cells/kg is administered once a week, up to 4 times percutaneously repeatedly. Depend on the DLT, the minimum dose is 0.5 x 10^6 cells/kg/once, 4 times in 22 days, and the maximum dose is 3 x 10^6 cells/kg/once, 4 times in 22 days.

Outcome(s)

• Primary Outcome: Adverse events including the dose limiting toxicity on iCAR-ILC-N101
• Secondary Outcome: Efficacy of iCAR-ILC-N101(Objective response rate, Disease control rate, Progression free survival, Overall survival)

Key inclusion & exclusion criteria

• Age minimum: >= 20age old
• Age maximum: Not applicable
