The following dosing information is available for ITOVEBI (inavolisib):
If adverse reactions occur, dosage interruption and/or reduction, or discontinuance of inavolisib may be necessary (see Table 1).

Table 1: Recommended Dosage Modifications for Inavolisib Adverse Reactions
Adverse Reaction Dosage Modification Based on Severity Hyperglycemia Fasting glucose levels (FPG or FBG) >ULN to 160 mg/dL: No adjustment required.

There are no adequate and well-controlled studies of inavolisib in pregnant women; however, based on findings of animal reproductive studies and its mechanism of action, inavolisib may cause embryo-fetal harm when administered to pregnant females.
It is not known whether inavolisib is distributed into human milk, or if the drug has any effects on the breastfed infant or on milk production. Because of the potential for serious adverse reactions to inavolisib in nursing infants, advise patients to discontinue breastfeeding during and for 1 week after final dose.
In the INAVO120 study, 15% of patients were >=65 years of age and 3% were >=75 years of age. Patients >=65 years of age in this study had a higher incidence of dosage modifications or interruptions of therapy due to adverse effects than younger patients (79 versus 68%). An insufficient number of patients >=65 years of age were included in clinical studies to determine whether they respond differently from younger patients.
