Warnings/Precautions
Embryo-fetal Toxicity
Based on findings in animals, leniolisib may cause fetal harm when administered to a pregnant woman. Administration of leniolisib to rats and rabbits during the period of organogenesis caused embryo-fetal toxicity including malformations at exposures that were 2-6 times higher than the maximum recommended human dose (MRHD) in patients with phosphoinositide 3-kinase delta (PI3Kδ) syndrome (APDS) based on AUC comparisons.
Verify the pregnancy status of patients of reproductive potential prior to starting treatment. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use highly effective methods of contraception during treatment and for 1 week after the last dose.
Vaccinations
Live, attenuated vaccinations may be less effective if administered during leniolisib treatment.
Specific Populations
Pregnancy
Leniolisib can cause fetal harm based on findings from animal studies. There are no available data on leniolisib use in pregnant women to inform a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes.
In animal reproduction studies, oral administration of leniolisib to pregnant rats and rabbits during the period of organogenesis at exposures approximately 2-6 times the MRHD on an AUC basis, produced embryofetal toxicity including malformations. Advise pregnant women of the potential risk to a fetus.
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage of clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Lactation
There are no data on the presence of leniolisib or its metabolites in human milk or the effects on the breastfed infant or milk production. Because of the potential for serious adverse reactions from leniolisib in the breastfed child, advise women not to breastfeed during treatment with the drug and for 1 week after the last dose.
Females and Males of Reproductive Potential
Based on findings from animal studies, leniolisib may cause fetal harm when administered to a pregnant woman.
Verify the pregnancy status in females of reproductive potential prior to initiating leniolisib phosphate.
Advise female patients of reproductive potential to use highly effective contraception during treatment with leniolisib and to continue contraception for 1 week after the last dose.
Pediatric Use
The safety and effectiveness of leniolisib for the treatment of activated phosphoinositide 3-kinase delta syndrome have been established in pediatric patients 12 years of age and older. Use of leniolisib for this indication is supported by evidence from an adequate and well-controlled study in adult and pediatric patients 12 years of age and older. There is no recommended dosage for pediatric patients 12 years of age and older who weigh less than 45 kg.
The safety and effectiveness of leniolisib phosphate have not been established in pediatric patients below the age of 12 years.
Geriatric Use
Because clinical studies of leniolisib did not include any patients 65 years of age and older, it cannot be determined whether they respond differently from younger adult patients.
Hepatic Impairment
Leniolisib is extensively (60%) metabolized by the liver. The effect of hepatic impairment on the pharmacokinetics of leniolisib has not been studied. The use of leniolisib in patients with moderate to severe hepatic impairment is not recommended.
Common Adverse Effects
Most common adverse reactions (incidence >10%) were headache, sinusitis, and atopic dermatitis.
Drug Interactions
Specific Drugs
It is essential that the manufacturer's labeling be consulted for more detailed information on interactions with this drug, including possible dosage adjustments. Interaction highlights:
-
Strong CYP3A4 Inhibitors: Avoid concomitant use.
-
Strong and Moderate CYP3A4 Inducers: Avoid concomitant use.
-
CYP1A2 Metabolized Drugs with a Narrow Therapeutic Index (NTIs): Avoid concomitant use.
-
BCRP, OATP1B1, and OATP1B3 Substrates: Avoid concomitant use.
Actions
Mechanism of Action
Leniolisib inhibits PI3K-delta by blocking the active binding site of PI3K-delta. In cell-free isolated enzyme assays, leniolisib was selective for PI3K-delta over PI3K-alpha (28-fold), PI3K-beta (43-fold), and PI3K-gamma (257-fold), as well as the broader kinome. In cell-based assays, leniolisib reduced pAKT pathway activity and inhibited proliferation and activation of B and T cell subsets. Gain-of-function variants in the gene encoding the p110-delta catalytic subunit or loss of function variants in the gene encoding the p85-alpha regulatory subunit each cause hyperactivity of PI3K-delta. Leniolisib inhibits the signalling pathways that lead to increased production of PIP3, hyperactivity of the downstream mTOR/AKT pathway, and to the dysregulation of B and T cells.
Advice to Patients
-
Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to inform their healthcare provider of a known or suspected pregnancy.
-
Advise females of reproductive potential to use highly effective contraceptive during treatment with leniolisib and for 1 week after the last dose.
-
Advise women not to breastfeed during treatment with leniolisib and for 1 week after the last dose.
-
Advise patients that leniolisib and certain other medicines can interact with each other.
-
Advise patients that leniolisib may be taken with or without food.
-
Instruct patients that if they miss a dose by more than 6 hours, skip the missed dose. Advise patients to take the next dose as scheduled.
-
Instruct patients that if vomiting occurs within 1 hour after taking leniolisib, take a dose as soon as possible.
