Phase 1B/2A Study of CTO1681 for the Prevention and Treatment of Cytokine Release Syndrome in Patients With Diffuse Large B-Cell Lymphoma Receiving Chimeric Antigen Receptor T-Cell Therapy
CytoAgents, Inc.
Summary
This is an interventional study to evaluate the use of CTO1681 in preventing or reducing CAR T-cell-induced toxicities like cytokine release syndrome (CRS). This study will enroll adult patients with DLBCL who are scheduled to receive CD19-directed CAR T-cell therapy. The first phase of the study will be open label with dose escalation. Participants will start taking CTO1681 just prior to receiving their CAR T-cell therapy and continue to take the study drug three times daily for a total of 15 days.
Description
The first phase of the study will be an open-label, dose escalation, safety assessment in a group of patients, and will also collect data to investigate the potential benefit of CTO1681, initiated prior to CAR T-cell therapy, in preventing or reducing certain toxicities or side effects associated with CAR T-cell therapy, such as cytokine release syndrome (CRS). Participants will start taking CTO1681 just prior to receiving their CAR T-cell therapy and continue to take the study drug three times daily for a total of 15 days. Participants will provide blood samples at specified points througho…
