SUMMARY OF INVENTION
Mesothelin (MSLN) is a cell-surface antigen which is highly expressed in solid tumors including mesothelioma, lung, pancreas, colorectal, breast, and ovarian. Investigators have developed a CAR T-cell technology targeting MSLN-expressing tumors. MSK clinical trials testing the MSLN CAR in mesothelioma (regional delivery) and triple-negative breast cancer (systemic delivery) have shown tumor-targeting ability with remarkable safety and evidence of efficacy, creating opportunities for cell therapies.
The non-T-cell (including NK, B cell, and macrophage) field of use for mesothelin CAR is available for license.
ADVANTAGES
- Ability to target multiple solid tumor and AML (acute myeloid leukemia) indications
- Mesothelin CAR is currently being tested in multiple clinical trials
- Supporting data using novel costimulatory domains and / or cell-intrinsic checkpoint inhibition (PD1 dominant negative receptor) within mesothelin CAR construct is also available
MARKET OPPORTUNITIES
Mesothelin CAR therapy has the potential to treat multiple solid malignancies and AML, with estimated annual incidence of >400K patients and a prevalence of 2M patients within the U.S alone.
