Study Details

Study Description

Brief Summary

Malignant melanoma have been reported to be characterized with high gp100 expression. Patients' autologous T cells will be isolated and transduced by GPA-TriMAR lentivirus to generate the GPA-TriMAR-T cells. When infused back to the patient, the GPA-TriMAR-T cells will recognize and kill target cells that express gp100(209-217) peptides in the form MHC-I complex, thus eliminating malignant melanoma from the body.

Condition or Disease Intervention/Treatment Phase
  • Biological: GPA-TriMAR-T
Early Phase 1

Detailed Description

GPA-TriMAR is a modified chimeric antigen receptor (CAR) that consist of three subunit in it's outer membrane domain. The outer membrane domain linked to the inner membrane 4-1BB/CD3ζ domain through the transmembrane domain, thus compose the complete chimeric antigen receptor. Patients' autologous T cells will be isolated and transduced by GPA-TriMAR lentivirus to generate the GPA-TriMAR-T cells. When infused back to the patient, the modified GPA-TriMAR-T cells will recognize and kill malignant melanoma cells in the body, and in the meanwhile the other two subunits function to stimulate the innate immune system and enhance GPA-TriMAR-T cells tumor Infiltration.

Arms and Interventions

Arm Intervention/Treatment
Experimental: GPA-TriMAR-T

Patients' autologous T cells will be isolated and transduced by GPA-TriMAR lentivirus to generate the GPA-TriMAR-T cells, and these cells will then be infused back into the patient for intervention.

Biological: GPA-TriMAR-T
Patients will undergo leukapheresis to isolate autologous T cells, these T cells will be activated and modified to express GPA-TriMAR in the manufacture facility, and eventually infused back into the body for treatment.
