Alethia is focusing on invasive carcinomas and on cancer-associated epithelial-to-mesenchymal transition, two areas for which there are very few therapeutic options.

AB-3A4 – invasive carcinomas

Alethia is developing a therapeutic monoclonal antibody for the treatment of ovarian cancer and other invasive carcinomas such as triple-negative breast tumors and renal cancer. AB-3A4 is an IgG1 monoclonal antibody against KAAG-1, a cell-surface protein involved in tumor invasion. Read more about AB-3A4

AB-16B5 – inhibition of EMT

Alethia is developing an inhibitor of EMT for the treatment of invasive carcinomas. AB-16B5 is a humanized IgG2 antibody against an EMT-inducing form of secreted clusterin (sCLU). AB-16B5 very efficiently blocks EMT and pre-clinical data indicate that animals xenografted with various carcinoma cells show an increase of response to standard of care chemotherapy as well as a reduction of invasion.
