This is a pilot, open-label study to assess the safety and feasibility of using investigational drug(s) as rescue therapies for CAR T cell related CRS and HLH-like syndrome (CRHLS).
This pilot, open-label trial will allow for co-enrollment of subjects participating in University of Pennsylvania-Sponsored, CCI-Initiated CAR T cell studies. As utilization of this investigational drug may be required emergently in the event of qualifying safety events post CAR T cell infusion, subjects may be consented/enrolled at the time they receive an investigational CAR T cell product. If/when use of this investigational drug is deemed clinically necessary, rescue therapy may then be initiated. Cohort 1: Will allow for the use of Tadekinig alfa, an interleukin-18 binding protein that b…
Inclusion Criteria: 1. Signed, written informed consent 2. Male or female patients age ≥ 18 years 3. Have been co-enrolled in a University of Pennsylvania-Sponsored, CCI-Initiated CAR T cell clinical trial. 4. Subjects of reproductive potential must agree to use acceptable birth control methods, as described in protocol Exclusion Criteria: 1. Pregnant or nursing (lactating) women. 2. Known hypersensitivity to the active substance or one of the excipients of the investigational product(s).
Tadekinig alfa will be administered via subcutaneous injection. The site of subcutaneous injection should be rotated to avoid injection site reactions; e.g. the outside of the thighs, arms, and the various quadrants of the anterior abdominal wall. * Injection #1/Day 1: o Loading dose of 4 mg/kg; Maximum dose of 350 mg. * Repeat Injection(s): 2 mg/kg/injection; Maximum dose of 160 mg/injection. Missed doses will not be made up. * Injection #2/Day 3: Approximately 48 hours (+/- 5 hours) after receipt of the 1st injection. * Injection #3/Day 5: Approximately 48 hours (+/- 5 hours) after receipt of the 2nd injection. * Continued Dosing (Optional): Approximately q48-72 hours; If the subject is responsive to initial therapy, but has ongoing symptoms of CRS/CRHLS.
