About this study

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.
