FT522 With Rituximab in Relapsed/Refractory B-Cell Lymphoma (FT522-101)

• Status: Recruiting
• Trial end date: 2044-06-30
• Target enrollment: 0
• Participant gender: All

Summary

This is a phase 1 study of FT522 administered with rituximab in participants with relapsed/refractory B-cell lymphoma (R/R BCL). The primary objectives of the study are to evaluate the safety and tolerability of FT522 in combination with rituximab, and to determine the recommended phase 2 dose (RP2D) of FT522 in combination with rituximab; each objective will be assessed with or without conditioning chemotherapy.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Fate Therapeutics
• Treatments: Bendamustine Hydrochloride; Cyclophosphamide; Fludarabine; Rituximab

• Receipt of any biological therapy, chemotherapy (except for rituximab), or any investigational therapy within 2 weeks prior to Day 1 or five half-lives, whichever is shorter; or localized radiation therapy to a target lesion within 14 days prior to Day 1

• Currently receiving or likely to require systemic immunosuppressive therapy, e.g., prednisone >5 mg daily, for any reason from Day -5 to Day 29, with the exception of corticosteroids as a pre medication required for conditioning chemotherapy or rituximab

• Prior allogeneic hematopoietic stem cell transplant (HSCT) or allogeneic chimeric antigen receptor (CAR) T-cell therapy within 6 months of Day 1, or ongoing requirement for systemic graft-versus-host disease (GvHD) therapy
