Efficacy and Safety of TILs in Treatment of Patients With Advanced or Metastatic Refractory Gynecological Cancer

Efficacy and Safety of Autologous Tumor-infiltrating Lymphocytes in Treatment of Patients With Advanced or Metastatic Refractory Gynecological Cancer: a Prospective Multicenter One-arm Phase Ⅱ Trial

Prospective, multicenter, single-arm, open label, interventional basket trial to evaluate autologous tumor-infiltrating lymphocytes (TILs) infusion followed by IL-2 after a non-myeloablative (NMA) lymphodepletion preparation for the treatment of patients with advanced or metastatic refractory gynecological cancer including cervical, ovarian, endometrial and breast carcinoma.

Study Overview

• Status: Not yet recruiting
• Conditions: Tumor Infiltrating Lymphocytes
• Intervention / Treatment: Biological: Autologous tumor-infiltrating lymphocytes

Detailed Description

Autologous tumor-infiltrating lymphocytes (TILs) infusion is highly personalized cancer immunotherapy with strong anti-tumor efficacy and tumor specificity. TILs were extracted from autologous fresh tumor tissues, and after ex vivo stimulation, activation and extensive expansion, are reinfused to patients. TIL-based therapies have only been offered in small phase I/II studies in a few centers and revealed a high objective response rate (ORR) in the treatment of metastatic, recurrent or advanced melanoma, non-small cell long carcinoma and cervical carcinoma. However, the efficacy of TIL-based therapies still needs more clinical trials to prove. In this proposal, a one-arm, open, multicenter, phaseⅠ/Ⅱ trial was designed to evaluate the efficacy and safety of autologous tumor-infiltrating lymphocytes in treatment of patients with advanced or metastatic refractory gynecological cancer including cervical, ovarian, endometrial and breast carcinoma.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Objective Response Rate	To evaluate the efficacy of TILs in patients with advanced or metastatic refractory malignant gynecological cancer including cervical, ovarian, endometrial and breast carcinoma based on the objective response rate (ORR) as assessed by the Independent Review Committee (IRC) per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1	Up to 6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
