Short answer Cell therapy and dependence: what to know Common questions Related questions SourcesNo, afamitresgene autoleucel injection is not addictive and does not cause dependence, cravings, or withdrawal.
It is a one-time infusion of your own T cells that have been modified to recognize a protein called MAGE-A4 on synovial sarcoma cells, so there is no daily dose to take, escalate, or stop. It is not a controlled substance and it does not act on the brain reward pathways involved in addiction. The medicines given around the infusion are a different story: opioids for pain, benzodiazepines for anxiety or nausea, and some sleep aids can be habit forming with longer use. Tell your oncology team about any history of substance use so they can choose supportive medicines with that in mind. Keep a simple list of every medicine you take at home and bring it to each visit.
Cell therapy and dependence: what to know
Common questions
Is Afamitresgene Autoleucel Injection addictive?
No. Afamitresgene autoleucel (Tecelra) is a one-time infusion of your own T cells that have been engineered to target MAGE-A4 on synovial sarcoma cells. It is not a controlled substance, it does not act on the brain reward pathways involved in addiction, and it does not cause cravings, tolerance, or withdrawal. You receive it once after lymphodepleting chemotherapy, so there is no ongoing dose to escalate or stop. What does deserve attention is the supportive care around it: opioids for pain and benzodiazepines or sleep aids can be habit forming with longer use. Tell your oncology team about any past substance use so they can plan those medicines carefully.
