    Abstract: Cysteine engineered anti-MUC16 antibodies are engineered by replacing one or more amino acids of a parent anti-MUC16 antibody with non cross-linked, reactive cysteine amino acids. Methods of design, preparation, screening, and selection of the cysteine engineered anti-MUC16 antibodies are provided. Cysteine engineered anti-MUC16 antibodies (Ab) are conjugated with one or more drug moieties (D) through a linker (L) to form cysteine engineered anti-MUC16 antibody-drug conjugates having Formula I: Ab-(L-D)p   I where p is 1 to 4. Diagnostic and therapeutic uses for cysteine engineered antibody drug compounds and compositions are disclosed.
