Clinical Trial

Disease: Solid Tumors, (NCT03970382)

Disease info:

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

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

Description

This is a first in human, single arm, open label, Phase 1a/1b study to determine the safety, feasibility, and efficacy of a single dose of NeoTCR-P1 T cells in participants with solid tumors.

The investigational agent in this protocol is NeoTCR P1, an autologous adoptive T cell therapy (ACT) for patients with solid cancer. NeoTCR P1 is composed of apheresis derived CD8 and CD4 T cells that are precision genome engineered to express one autologous TCR of native sequence that targets a neoepitope (neoE) presented by human leukocyte antigen (HLA) receptors exclusively on the surface of that patient's tumor cells and not on other cells in the body.
