Discovery and preliminary clinical findings of MK-6598, a potent and selective inhibitor of the immune checkpoint IL4I1 (AACR 2025) - P1 | "The only response was in a pt with mismatch repair-deficient endometrial cancer that progressed on prior pembro achieved a partial response after crossing over from MK-6598 monotherapy to MK-6598 plus pembro. These data suggest that despite its ability to inhibit IL4I1 protein, MK-6598 has limited antitumor activity as monotherapy or in combination with pembro in pts with previously treated advanced solid tumors."
