Publication number: 20210023094Abstract: This invention relates generally to antibody-drug conjugates (ADCs). In particular, the invention relates to ADCs which comprise an antibody or antigen-binding fragment thereof which binds to prostate-specific membrane antigen (PSMA) and is conjugated to monomethylauristatin norephedrine or monomethylauristatin phenylalanine. The antibody-drug conjugate has a PC-3™ cell to C4-2 or LNCaP™ cell selectivity of at least 250. The invention also relates, in part, to compositions of and methods of using the ADCs. The methods provided include, for example, methods for treating a PSMA-mediated disease.Type: ApplicationFiled: July 6, 2020Publication date: January 28, 2021Applicant: PSMA Development Company, LLCInventors: Dangshe Ma, Paul J.
