What this trial studies

This pilot, open-label trial evaluates the safety and feasibility of Tadekinig alfa, an interleukin-18 binding protein, as a rescue therapy for patients experiencing cytokine release syndrome (CRS) and HLH-like syndrome following CAR T cell therapy. Participants will be co-enrolled in University of Pennsylvania-sponsored CAR T cell studies and may receive the investigational drug if they experience qualifying safety events post-infusion. The study aims to determine if Tadekinig alfa can effectively mitigate severe inflammatory responses associated with CAR T cell treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are co-enrolled in a University of Pennsylvania-sponsored CAR T cell clinical trial.

Not a fit: Patients who are pregnant, nursing, or have known hypersensitivity to the investigational drug will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve outcomes for patients suffering from severe inflammatory responses after CAR T cell therapy.

How similar studies have performed: While this approach is novel in the context of CAR T cell therapy, similar strategies targeting inflammatory responses have shown promise in other settings.
