FT825/ONO-8250, an Off-the-Shelf, HER2 CAR-T, with or Without Monoclonal Antibodies in Advanced Solid Tumors

Purpose

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.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
Regimen A: FT825
Participants with advanced HER2-expressing solid tumors receive FT825 following chemotherapy in Cycle 1 (each cycle is approximately 61 days). Based on the safety, tolerability, and radiographically confirmed clinical benefit to treatment in Cycle 1, participants may be considered for an additional treatment cycle (Cycle 2 retreatment).
  • Drug: FT825
    FT825 will be administered as an intravenous (IV) infusion at planned dose levels.
    Other names:
    • ONO-8250
  • Drug: Fludarabine
    Fludarabine will be administered as an IV infusion at planned dose levels.
    Other names:
    • FLUDARA
  • Drug: Cyclophosphamide
    Cyclophosphamide will be administered as an IV infusion at planned dose levels.
  • Drug: Bendamustine

Experimental
Regimen B: FT825 + Cetuximab
Participants with advanced epidermal growth factor receptor (EGFR)-expressing solid tumors receive FT825 in combination with cetuximab following chemotherapy in Cycle 1 (each cycle is approximately 61 days). Based on the safety, tolerability, and radiographically confirmed clinical benefit to treatment in Cycle 1, participants may be considered for an additional treatment cycle (Cycle 2 retreatment).
