Modality-specific risk
QTc prolongation via hERG inhibition by revumenib and metabolite M1
“Based on findings from non-GLP and GLP assays, revumenib and its primary metabolite M1 have the potential to block the hERG channel and contribute to QTc prolongation.”

Anti-drug antibodies: animals
Not stated in public reviews
Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.
Anti-drug antibodies: patients
Not applicable (small molecule); no immunogenicity studies conducted
“FDA acknowledges that no immunogenicity studies were conducted. As revumenib is a small molecule, there should be little risk of immunogenicity.”
