Joenja Prescribing Information
JOENJA is indicated for the treatment of activated phosphoinositide 3-kinase delta (PI3Kδ) syndrome (APDS) in adult and pediatric patients 12 years of age and older.
Testing Prior to Treatment with JOENJA
Verify pregnancy status in females of reproductive potential prior to initiating treatment with JOENJA [see Warnings and Precautions , and Use in Specific Populations ].
Recommended Dosage and Administration
The recommended dosage of JOENJA in adult and pediatric patients 12 years of age and older weighing 45 kg or greater is 70 mg administered orally twice daily approximately 12 hours apart, with or without food. There is no recommended dosage for patients weighing less than 45 kg.
Advise patients that if a dose is missed by more than 6 hours, wait and take the next dose at the usual time.
Advise patients that if vomiting occurs within 1 hour after taking JOENJA, take JOENJA as soon as possible. If vomiting occurs more than 1 hour after dosing, wait and take the next dose at the usual time.
Tablets: 70 mg (leniolisib), yellow, oval-shaped, biconvex, bevelled edge film-coated tablet debossed with "70" on one side and "LNB" on the other side.
Pregnancy
Risk Summary
JOENJA can cause fetal harm based on findings from animal studies. There are no available data on JOENJA 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 (see Data). 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.
Data
Animal Data
Leniolisib was administered orally to pregnant rats at doses of 10, 30, and 120 mg/kg/day during the period of organogenesis from gestation Day 6 to Day 17. Leniolisib at a dose of 120 mg/kg/day was associated with decreased fetal body weight, visceral and skeletal variations, and external, visceral, and skeletal malformations (eye bulge, microphthalmia, anophthalmia, and reduction in orbital socket size) in the presence of maternal toxicity (decrease in body weight gain) at exposures approximately 6 times the MRHD on an AUC basis. No developmental toxicity was observed in rats at an exposure approximately 2 times the MRHD (on an AUC basis at a maternal oral dose of 30 mg/kg/day).
Leniolisib was administered orally to pregnant rabbits at doses of 10, 30, and 100 mg/kg/day during the period of organogenesis from gestation Day 7 to Day 20. Leniolisib at a dose of 100 mg/kg/day was associated with skeletal variations as well as visceral and skeletal malformations (microphthalmia and reduction in orbital socket size) in the presence of maternal toxicity (decrease in body weight gain) at exposures approximately 2 times the MRHD on an AUC basis. No developmental toxicity was observed in rabbits at an exposure approximately 0.3 times the MRHD (on an AUC basis at a maternal oral dose of 30 mg/kg/day).
Pre- and post-natal development studies with leniolisib have not been conducted.
Lactation
Risk Summary
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 JOENJA and for 1 week after the last dose.
Females and Males of Reproductive Potential
Based on findings from animal studies, JOENJA may cause fetal harm when administered to a pregnant woman [see Use in Specific Populations ].
Pregnancy Testing
Verify the pregnancy status in females of reproductive potential prior to initiating JOENJA.
Contraception
Females
Advise female patients of reproductive potential to use highly effective contraception during treatment with JOENJA and to continue contraception for 1 week after the last dose.
Pediatric Use
The safety and effectiveness of JOENJA for the treatment of activated phosphoinositide 3-kinase delta syndrome have been established in pediatric patients 12 years of age and older. Use of JOENJA 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 [see Clinical Studies ]. There is no recommended dosage for pediatric patients 12 years of age and older who weigh less than 45 kg [see Dosage and Administration ].
The safety and effectiveness of JOENJA have not been established in pediatric patients below the age of 12 years.
Juvenile Animal Toxicity Data
Studies were conducted with leniolisib in juvenile rats starting at postnatal day (PND) 7 (the equivalent of a human newborn) to PND 77 (the equivalent of a human adult). Death was observed in juvenile rats that received 90 mg/kg/day, approximately 2-4 times the MRHD on an AUC basis and occurred primarily during the pre-weaning period (PND 9 to PND 15). Changes in the onset of puberty (delays in males and accelerations in females) were observed in juvenile rats at equal to or greater than 30 mg/kg/day leniolisib, which is one half to equivalent to, the MRHD on an AUC basis. A no effect dose level was identified at an exposure approximately 0.2 times the MRHD on an AUC basis.
Geriatric Use
Because clinical studies of JOENJA 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 JOENJA in patients with moderate to severe hepatic impairment is not recommended [see Clinical Pharmacology ].
None.
Embryo-Fetal Toxicity
Based on findings in animals, JOENJA 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 APDS patients 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 [see Dosage and Administration , Use in Specific Populations ].
Vaccinations
Live, attenuated vaccinations may be less effective if administered during JOENJA treatment.
