RESEARCH SUMMARY

Dr. Hassan has played a pivotal role in validating the tumor differentiation antigen mesothelin as a target for cancer therapy and development of mesothelin targeted immunotherapy. His current research focus is on developing mesothelin directed adoptive cellular therapies including clinical trials of T cell receptor fusion constructs, gavo-cel and TC-510. Additionally, his lab has developed highly effective anti-mesothelin hYP218 CAR T cells that bind mesothelin close to the cell membrane and will enter the clinic later this year. The Hassan lab also studies the genetics of mesothelioma and is leading a prospective trial of early cancer detection in patients and their family members with germline mutations in the BAP1 cancer pre-disposition gene.

Covers

Hassan et al., Nature Medicine 2023

Mesothelin-targeting T cell receptor fusion construct cell therapy in refractory solid tumors: phase 1/2 trial interim results.

Published Date

T cell therapy

In this issue, Hassan et al. show that engineered HLA-independent T cells specific for mesothelin, an antigen that is overexpressed in many cancers, exhibit toxicities as well as anti-tumor activity in patients with treatment-refractory mesothelioma or ovarian cancer. The school of omnivorous koi fish on the cover represents the T cells, which are shown attacking a solid tumor.
