In the clinical study, early side effects were managed at an Authorized Treatment Center

Some side effects may happen shortly after your TECARTUS treatment. Staying at the hospital for 7 days and then nearby for about 4 weeks helps your care team make sure you get the medical attention you may need.

Early side effects in the clinical study included:

Cytokine Release Syndrome (CRS)
