Clinical Trial

Disease: Solid Tumor, Adult, (NCT03747965)

Disease info:

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

The word tumor does not always imply cancer. In discussing tumors that are malignant (cancerous), however, the term solid tumor is used to distinguish between a localized mass of tissue and leukemia.

More than 1.9 million new cancer cases are expected to be diagnosed in the US in 2023.

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

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