Warnings
•Hyperglycemia
•Severe hyperglycemia can occur in patients treated with Inavolisib. Increased fasting glucose occurred in 85% of patients treated with Inavolisib, including 22% of patients with Grade 2 (FPG > 160 to 250 mg/dL), 12% with Grade 3 (FPG > 250 to 500 mg/dL), and 0.6% with Grade 4 (FPG > 500 mg/dL) events. Among patients with hyperglycemia, the median time to first onset was 7 days (range: 2 to 955 days). Hyperglycemia led to dose interruption in 28%, to dose reduction in 2.5%, and to discontinuation of Inavolisib in 1.2% of patients. The safety of ITOVEBI in patients with Type 1 diabetes mellitus, or Type 2 diabetes mellitus requiring ongoing anti-hyperglycemic treatment have not been studied. Before initiating treatment with Inavolisib, test fasting glucose levels (FPG or FBG), HbA1C levels, and optimize fasting glucose. After initiating treatment with Inavolisib, or in patients who experience hyperglycemia after initiating treatment with Inavolisib, monitor or self-monitor fasting glucose levels once every 3 days for the first week (Day 1 to 7), then once every week for the next 3 weeks (Day 8 to 28), then once every 2 weeks for the next 8 weeks, then once every 4 weeks thereafter, and as clinically indicated. Monitor HbA1C every 3 months and as clinically indicated. Manage hyperglycemia with anti-hyperglycemic medications as clinically indicated. During treatment with anti-hyperglycemic medication, continue monitoring fasting glucose levels. Patients with a history of well-controlled Type 2 diabetes mellitus may require intensified anti-hyperglycemic treatment and close monitoring of fasting glucose levels. Based on the severity of the hyperglycemia, ITOVEBI may require dose interruption, reduction, or discontinuation.
•Stomatitis
•Severe stomatitis can occur in patients treated with INAVOLISIB. Stomatitis occurred in 51% of patients treated with INAVOLISIB in combination with palbociclib and fulvestrant, including Grade 3 events in 6% of patients. The median time to first onset was 13 days (range: 1 to 610 days). Stomatitis led to interruption of INAVOLISIB in 10%, to dose reduction in 3.7%, and to discontinuation of INAVOLISIB in 0.6% of patients. Monitor patients for signs and symptoms of stomatitis. Withhold, reduce dose, or permanently discontinue INAVOLISIB based on severity.
•Diarrhea
•Severe diarrhea, including dehydration and acute kidney injury, can occur in patients treated with Inavolisib. Diarrhea occurred in 48% of patients treated with Inavolisib in combination with palbociclib and fulvestrant, including Grade 3 events in 3.7% of patients. The median time to first onset was 15 days (range: 2 to 602 days). Anti-diarrheal medicines were used in 28% (46/162) of patients who received ITOVEBI in combination with palbociclib and fulvestrant to manage symptoms. Dose interruptions were required in 7% of patients, and dose reductions occurred in 1.2% of patients. Monitor patients for signs and symptoms of diarrhea. Advise patients to increase oral fluids and start anti-diarrheal treatment at the first sign of diarrhea while taking ITOVEBI. Withhold, reduce dose, or permanently discontinue ITOVEBI based on severity
•Embryo-Fetal Toxicity
•Based on findings in animals and its mechanism of action, INAVOLISIB can cause fetal harm when administered to a pregnant woman. In an animal reproduction study, oral administration of inavolisib to pregnant rats during the period of organogenesis caused adverse developmental outcomes, including embryo-fetal mortality, structural abnormalities, and alterations to growth at maternal exposures approximately equivalent to the human exposure at the recommended dose of 9 mg/day based on area under the curve (AUC). Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective non-hormonal contraception during treatment with INAVOLISIB and for 1 week after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with INAVOLISIB and for 1 week after the last dose.
