Tadekinig Alfa for CAR T Cell Side Effects

This study is testing Tadekinig alfa (IL-18BP) as a rescue treatment for serious side effects that can happen after CAR T cell therapy. These side effects include Cytokine Release Syndrome (CRS) and HLH-like syndrome (CRHLS), which are severe inflammatory reactions. Tadekinig alfa works by blocking a protein called IL-18, which is involved in these inflammatory conditions. The study will look at how safe Tadekinig alfa is and how practical it is to use in about 10 adult patients (18 years or older) who are already part of a CAR T cell clinical trial at the University of Pennsylvania. The main goal is to see if this treatment is safe and feasible within 28 days of starting it.

Study design
This is a pilot, open-label study, meaning both you and your doctors will know you are receiving Tadekinig alfa. It plans to enroll about 10 participants.
What's involved
You would receive Tadekinig alfa as an injection under the skin, with injection sites rotated. You must already be enrolled in a University of Pennsylvania-sponsored CAR T cell clinical trial. If you can become pregnant, you must agree to use acceptable birth control.
Compensation
Not stated in the trial record.
Follow-up
The primary safety and feasibility will be evaluated at 28 days.
