PCA062 is a P-cadherin specific antibody drug conjugate (ADC) that utilizes the clinically validated SMCC-DM1 linker-payload to mediate potent cytotoxicity in cell lines expressing high levels of P-cadherin in vitro, while displaying no specific activity in P-cadherin negative cell lines. High cell surface P-cadherin is necessary, but not sufficient, to mediate PCA062 cytotoxicity. In vivo, PCA062 demonstrated high serum stability and a potent ability to induce mitotic arrest. In addition, PCA062 was efficacious in clinically relevant models of P-cadherin expressing cancers, including breast, esophageal and head and neck. Preclinical non-human primate toxicology studies demonstrated a favorable safety profile that supports clinical development. Genome-wide CRISPR screens reveal that expression of the multi-drug resistant gene ABCC1 and the lysosomal transporter SLC46A3 differentially impact tumor cell sensitivity to PCA062. The preclinical data presented here suggest that PCA062 may have clinical value for treating patients with multiple cancer types including basal-like breast cancer. PCA062, a P-cadherin targeting antibody-drug-conjugate, displays potent anti-tumor activity against P-cadherin-expressing malignancies.,Sheng Q, D'Alessio JA, Menezes DL, Karim C, Tang Y, Tam A, Clark S, Ying C, Connor A, Mansfield KG, Rondeau JM, Ghoddusi M, Geyer FC, Gu J, McLaughlin ME, Newcombe R, Elliott G, Tschantz WR, Lehmann S, Miller K, Huber T, Rendahl KG, Jeffry U, Pryer NK, Lees E, Kwon P, Abraham JA, Damiano JS, Abrams TJ Mol Cancer Ther. 2021 Apr 20. pii: 1535-7163.MCT-20-0708. doi:, 10.1158/1535-7163.MCT-20-0708.
