Clinical Trial

Disease: Solid Tumor, Adult, (NCT03747965)

Disease info:

A solid tumour is an abnormal mass of tissue that usually does not contain cysts or liquid areas. Solid tumours may be benign (not cancer), or malignant (cancer). Solid tumour types are named according to the type of cell they originate from. Examples of solid tumours are sarcomas, carcinomas, and lymphomas. Leukaemias (cancers of the blood) generally do not form solid tumours.

The word tumour does not always imply cancer. In discussing tumours that are malignant (cancerous), however, the term solid tumour is used to distinguish between a localised mass of tissue and leukaemia.

 

Frequency:
Excluding non-melanoma skin cancers, over 2 million new cancer cases are expected to be diagnosed in the US in 2025.

Description

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.
