Clinical Trial

Disease: Multiple Solid Tumor Adult, (NCT03545815)

Disease info:

An abnormal mass of tissue that usually does not contain cysts or liquid areas. Solid tumors may be benign (not cancer), or malignant (cancer). Different types of solid tumors are named for the type of cells that form them. Examples of solid tumors are sarcomas, carcinomas, and lymphomas. Leukemias (cancers of the blood) generally do not form solid tumors.

 

Frequency:
Based on projections, cancer deaths will continue to rise with an estimated 9 million people dying from cancer in 2015, and 11.4 million dying in 2030.
Official title:
Phase I Study to Evaluate Treatment of CRISPR-Cas9 Mediated PD-1 and TCR Gene-knocked Out Chimeric Antigen Receptor (CAR) T Cells in Patients With Mesothelin Positive Multiple Solid Tumors.

Description

Multiple solid tumors have positive targets of mesothelin expressed on the surfaces of the tumor cells, we use the technique of CRISPR-Cas9 to knocked out the PD-1 and TCR of chimeric antigen receptor (CAR) T cells to effect the immuno-microenvironment around tumors.

  1. To evaluate the feasibility and safety of CRISPR-Cas9 mediated PD-1 and TCR gene-knocked out chimeric antigen receptor (CAR) T cells in patients with mesothelin positive multiple solid tumors.
  2. To evaluate the duration of in vivo persistence of transferred CAR-T cells.
  3. To observe and measure anti-tumor responses for patients with detectable mesothelin positive tumor lesions.
