Phase I

A Phase 1 Study of FT825/ONO-8250, an Off-the-Shelf CAR T-Cell Therapy, With or Without Monoclonal Antibodies, in HER2-Positive or Other Advanced Solid Tumor

  • Study HIC#:2000036812
  • Last Updated:12/20/2024

This is a phase 1 study designed to evaluate the safety, tolerability, and antitumor activity of FT825 (also known as ONO-8250) with or without monoclonal antibody therapy following chemotherapy in participants with advanced human epidermal growth factor receptor 2 (HER2)-positive or other advanced solid tumors. The study will consist of a dose-escalation stage, followed by an expansion stage to further evaluate the safety and activity of FT825 in indication-specific cohorts.
