Study Details
Study Description
Brief Summary
An open-label, single-arm, single-dose escalation and multiple-dose expansion clinical study of cell therapy to observe and to evaluate the tolerance, the pharmacokinetic characteristics, the safety, and the efficacy of ScTIL210 in the treatment of malignant

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: ScTIL210 This trial is designed single arm. All the subjects enrolled will receive the experimental intervention, ScTIL210(Super circulating tumor infiltrating lymphocytes). |
Biological: Super circulating tumor infiltrating lymphocytes(ScTIL)
Peripheral blood mononuclear cells (PBMCs) are used for cell preparation. PD-1(programmed death 1) positive T cells are isolated from peripheral blood by blood cell apheresis method and transduced with lentivirus loaded with "enhanced receptor" and "superamplification factor". The obtained ScTIL is used for one-time intravenous infusion.

Outcome Measures
Primary Outcome Measures
- The safety of ScTIL210 [24 weeks post infusion]
To assess if the ScTIL210 product will be safe to the subjects, as assessed by the incidence of treatment-related adverse events, in the treatment of malignant solid tumors.
Secondary Outcome Measures
- The in vivo dynamic variation of reinfused ScTIL210 [24 weeks post infusion]
To assess the percentage of PD1 positive cell in total lymphocytes of peripheral blood along a series of time points after reinfusion of ScTIL210 as measured by flow cytometry.
- The efficacy of ScTIL210 in the treatment of malignant solid tumors [24 weeks post infusion]
To assess the clinical efficacy of ScTIL210 in the treatment of malignant solid tumors, as assessed by duration of response(DOR), i.e., time from complete remission (CR) or partial remission (PR) to disease progression (PD), or to death, or to last tumor evaluation.
