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)

CRS can cause fever, chills, fatigue, rapid heartbeat, nausea, not enough oxygen in the body, weakness, and low blood pressure (dizziness or lightheadedness, headache, feeling tired, short of breath). Severe CRS can be a life-threatening problem that requires medical care.
