QTcF is calculated using Fridericia’s Formula (QTcF): QTcF = QT/(RR0.33). ; a. Correction of suspected drug-induced QTcF prolongation can be attempted at the investigator’s discretion and only if clinically safe to do so with either discontinuation of the offending drug or switch to another drug not known to be associated with QTcF prolongation. ; b.

Pirtobrutinib capsules should be taken 2 hours before an H2-receptor antagonist. Avoid co-administration of pirtobrutinib capsules with proton pump inhibitors).
