Mesothelin-Targeted Antibody Drug Conjugate
PF-08052666 (SGN-MesoC2) is an investigational compound. Its safety and efficacy have not been established.
Overview + Rationale
- Mesothelin (MSLN) is a 40-kDa cell surface differentiation antigen present on normal mesothelial cells and plays a role in the regulation of cell proliferation, growth, and adhesion signaling1
- Overexpression of mesothelin has been identified in many different tumor types (including lung and ovarian cancers) and in hematological malignancies such as acute myeloid leukemia2
- It’s limited expression in normal tissues and overexpression in tumor tissues can result in reduced nonspecific toxicity, making MSLN an attractive target for oncology drug development3
- PF-08052666 (SGN-MesoC2) is an ADC that targets human mesothelin4
- PF-08052666 (SGN-MesoC2) consists of an anti-MSLN mAb conjugated to SGD-12280 (a novel topoisomerase 1 inhibitor) by a cleavable methylsulfonylpyrimidine tripeptide linker4
