Genetically Modified T Cells Treating Malignant Tumors

Early Phase 1

Recruiting

• Conditions: Solid Tumor
• Interventions: Biological: CAR-T cell reinfusion

• Registration Number: NCT06515626
• Lead Sponsor: Yi Zhang

Brief Summary

To observe the safety, tolerability and initial effectiveness of gene modified T cell therapy in patients with malignant tumors in First Affiliated Hospital of Zhengzhou University, China.

Detailed Description

The study population included subjects with malignant tumors confirmed by histopathology or cytology, including: non-small cell lung cancer, esophageal squamous cell carcinoma, gastric cancer, colorectal cancer, liver cancer, pancreatic cancer, kidney cancer, cervical squamous cell carcinoma, ovarian cancer, breast cancer, melanoma, brain glioma, lymphoma, etc.

The study is aimed to observe the safety, tolerability and initial effectiveness of gene modified T cell therapy in patients with malignant tumors.To observe Progression-Free Survival (PFS) and Overall survival (OS) after the application of gene modified T cell therapy in patients with malignant tumors, and to evaluate the Disease Control Rate (Disease Control Rate). DCR, Clinical Benefit Rate (CBR), Quality of Life (QOL).And explore the diversity of T cell receptors and proportion of lymphocyte subsets in subjects treated with gene-modified T cell therapy for malignant tumors changes in distribution and count, immune cell function, and serum cytokine levels.

Arm && Interventions

Group	Intervention	Description
subject	CAR-T cell reinfusion	-

Primary Outcome Measures

Name	Time	Method
PFS	up to 36 months	Progression-Free-Survival (PFS) is defined as admission to the group according to imaging specialists based on RECIST 1.1 review when disease progression or death from any cause was first recorded, whichever came first.

Secondary Outcome Measures

Name	Time	Method
DOR	up to 36 months	Duration of response (DOR). For subjects with confirmed CR or PR, duration of remission is the time from first recording to evidence of CR or PR until disease 2 progression (according to RECIST 1.1) or death from any cause, whichever occurs first.
ORR	up to 36 months	Objective response rate（ORR） refers to the proportion of subjects in the analysis population who achieved complete response (CR) or partial response (PR).
OS	up to 36 months	Overall survival (OS) is the time from enrollment to death from any cause
