Idecabtagene Vicleucel and Cytokine Release Syndrome: is the FAERS signal real?
A written Bradford Hill assessment of one drug–event pair. The grade is a judgement about the signal, not a statement that this drug causes this event in any one person; FAERS counts are reports, not rates.
Idecabtagene Vicleucel ↔ Cytokine Release Syndrome
n=696 co-reports · PRR 651.3 · ROR 1513.5
Idecabtagene vicleucel (Abecma) is a BCMA-directed CAR T-cell therapy. CRS is the expected on-target pharmacological effect; the label carries a boxed warning. 475 co-reports (PRR 188.8) reflect universal occurrence.
Boxed warning: Abecma label (CRS). Registration trial.
