Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 43 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2022-10-12
• Study Completion Date: 2025-10-30

Brief Summary

20-60 participants are expected to be enrolled for the Phase I clinical trial which is further divided into two parts: a "3+3" dose escalation study and an expanded enrollment study.

The Phase I clinical trial is expected to be finished in 36 months. To be specific, the dose escalation study plans to include patients with advanced malignant solid tumors with clear pathological diagnosis, including melanoma, cervical cancer, head and neck squamous cell tumors, non-small cell lung cancer and breast cancer, etc.; while the expanded enrollment study plans to include those with melanoma, cervical cancer, and head and neck squamous cell tumors.

Study Groups

Experimental: Cohort 1

dose escalation group: participants with advanced solid tumors using cryopreserved GC101 TIL

Group Type: EXPERIMENTAL

TIL therapy

Intervention Type: DRUG

A tumor sample is resected from each participant and cultured ex vivo to expand the population of autologous tumor infiltrating lymphocytes injection (GC101 TIL). After lymphodepletion, patients are infused GC101 TIL followed sintilimab.

Experimental: Cohort 2

participants with advanced malignant melanoma using cryopreserved GC101 TIL

Group Type: EXPERIMENTAL

TIL therapy

Intervention Type: DRUG

A tumor sample is resected from each participant and cultured ex vivo to expand the population of autologous tumor infiltrating lymphocytes injection (GC101 TIL). After lymphodepletion, patients are infused GC101 TIL followed sintilimab.

Experimental: Cohort 3

participants with advanced NSCLC using cryopreserved GC101 TIL

Group Type: EXPERIMENTAL

TIL therapy

Intervention Type: DRUG

A tumor sample is resected from each participant and cultured ex vivo to expand the population of autologous tumor infiltrating lymphocytes injection (GC101 TIL). After lymphodepletion, patients are infused GC101 TIL followed sintilimab.

Experimental: Cohort 4

participants with advanced HNSCC using cryopreserved GC101 TIL

Group Type: EXPERIMENTAL

TIL therapy

Intervention Type: DRUG

A tumor sample is resected from each participant and cultured ex vivo to expand the population of autologous tumor infiltrating lymphocytes injection (GC101 TIL). After lymphodepletion, patients are infused GC101 TIL followed sintilimab.

Experimental: Cohort 5

participants with advanced cervical cancer using cryopreserved GC101 TIL

Group Type: EXPERIMENTAL

TIL therapy

Intervention Type: DRUG

A tumor sample is resected from each participant and cultured ex vivo to expand the population of autologous tumor infiltrating lymphocytes injection (GC101 TIL). After lymphodepletion, patients are infused GC101 TIL followed sintilimab.
