Talquetamab 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.
Talquetamab ↔ Cytokine Release Syndrome
n=489 co-reports · PRR 270.0 · ROR 354.5
Talquetamab is a BCMA-directed bispecific antibody for multiple myeloma. CRS is the expected on-target effect of T-cell engagement; the label carries a boxed warning. 388 co-reports (PRR 925.7) reflect near-universal occurrence in a smaller treated population.
Boxed warning: talquetamab label (CRS). Registration trial.
