• Sacituzumab tirumotecan (sac-TMT) monotherapy shows promising antitumor activity in patients with previously treated advanced endometrial cancer, with an objective response rate (ORR) of 34.1%.
• In patients with previously treated advanced ovarian cancer, sac-TMT monotherapy achieved an ORR of 40.0% and a disease control rate (DCR) of 75.0%.
• The phase 2 KL264-01 trial highlights a manageable safety profile for sac-TMT, with common treatment-related adverse events including anemia and decreased white blood cell count.
• A phase 3 trial, TroFuse-005 (NCT06132958), is underway to further evaluate sac-TMT versus chemotherapy in advanced endometrial cancer patients.
