Summary
Brief summary (as posted)
Despite the consequent use of Tocilizumab together with conventional antipyretics at early/first signs of emerging CRS, CRS (and eventually the subsequent development of ICANS) remain a major concern for patients. This study aims to identify safety and efficacy of prophylactic Tocilizumab treatment. In particular, to explore whether prophylactic Tocilizumab treatment can decrease the incidence and severity of CRS (and subsequent eventual neurotoxicity) following CAR-T-treatment.

- EXPERIMENTAL
- label
- Tocilizumab prophylactic
- description
- In the experimental arm, patients will receive a single standard dose of Tocilizumab (Actemra®) 8 mg/kg b.w. intravenously infused over 1 hour in 250 ml NaCl 0.9%, with completion of the infusion 1 hour prior to the infusion of the CAR-T cells. Prior to Tocilizumab administration, no specific premedication is given. The treatment of eventual subsequent CRS will be identical as in patients in the standard arm.

- type
- ACTIVE_COMPARATOR
- label
- Tocilizumab on demand
- description
- In the standard arm, patients will receive conventional antipyretics and Tocilizumab at first clinical signs (being grade 1 or higher) of emerging CRS. Tocilizumab will be given at the standard-dose of 8 mg/kg b.w. intravenously over one hour in 250 ml NaCl 0.9%, and it will be repeated after 8 hours for a maximum of four administrations in patients with ongoing signs of CRS. Prior to Tocilizumab administration, no specific premedication is given.
