Short answer What to expect after cell therapy Common questions Related questions Sources**If you respond to afamitresgene autoleucel (Tecelra), tumor shrinkage may first be detected about 4 to 5 weeks after your infusion.**
The current FDA prescribing information reports a median time to response of 4.6 weeks, meaning half of responses occurred sooner and half later. Your cancer may respond later or may not shrink with treatment. This timing starts with your infusion, excluding the time needed to collect and prepare your cells and give chemotherapy beforehand. Your oncology team uses follow-up scans to assess benefit, so keep your scan appointments and report new symptoms promptly.
What to expect after cell therapy
Common questions
How long does Afamitresgene Autoleucel Injection take to work?
Afamitresgene autoleucel (Tecelra) can produce measurable tumor shrinkage about 4 to 5 weeks after infusion in people who respond. The FDA prescribing information reports a median time to response of 4.6 weeks. This is not a deadline or a guarantee that your cancer will shrink. Cell collection, manufacturing, and chemotherapy happen before this response clock starts. Your oncologist uses scans to check whether treatment is working; symptoms alone cannot confirm a response. Keep follow-up visits and contact your treatment team immediately for fever, trouble breathing, or confusion.
