METHODS FOR THE USE OF A B7-H3 ANTIBODY-DRUG CONJUGATE IN COMBINATION WITH A PD-1 X CTLA-4 BISPECIFIC MOLECULE

The present disclosure is directed in part to dosing regimens for administering a humanized anti-B7-H3 antibody conjugated to a duocarmycin moiety (a "B7-H3-ADC") for the treatment of cancer, particularly a cancer associated with expression of B7-H3. The disclosure in part concerns the use of such B7-H3-ADC in combination with a bispecific molecule capable of binding to PD-1 and CTLA-4 ("PD-1 X CTLA-4 bispecific molecule"). The disclosure in part concerns the use of such B7-H3-ADC in combination with lorigerlimab for the treatment of cancer. The disclosure in part concerns the use of MGC018 in combination with lorigerlimab for the treatment of cancer. The disclosure is directed in part to the use of such molecules, and to the use of pharmaceutical compositions and pharmaceutical kits that contain such molecules and that facilitate the use of such dosing regimens in the treatment of cancer.
