Dosage and Administration
2 DOSAGE AND ADMINISTRATION Verify pregnancy status in females of reproductive potential prior to initiating treatment. ( 2.1 , 5.1 ) Recommended dosage: 70 mg administered orally twice daily approximately 12 hours apart, with or without food, in adult and pediatric patients 12 years of age and older and weighing ≥ 45kg. ( 2.2 ) 2.1 Testing Prior to Treatment with JOENJA Verify pregnancy status in females of reproductive potential prior to initiating treatment with JOENJA [see Warnings and Precautions ( 5.1 ), and Use in Specific Populations ( 8.1 , 8.3 )] . 2.2 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.
Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Risk of Hypersensitivity Reactions, Including Anaphylaxis [see Warnings and Precautions (5.3) ] Most common adverse reactions (incidence > 10%) were headache, sinusitis, and atopic dermatitis. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Pharming Healthcare Inc. at 1-800-930-5221 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of JOENJA reflects exposure based on 38 adult and pediatric patients 12 years of age and older with activated phosphoinositide 3-kinase delta (PI3Kδ) syndrome (APDS) from the placebo-controlled portion of Study 2201 [see Clinical Studies ( 14 )] and additional open-label clinical safety data. Thirty-seven of 38 patients received JOENJA 70 mg orally twice daily for at least 25 weeks and 66% were exposed for 96 weeks or longer. Median duration of JOENJA treatment was approximately 2 years, and 4 patients had more than 5 years of JOENJA exposure. The data below are based on the 12-week, placebo-controlled portion of Study 2201 in which either JOENJA 70 mg (N=21) or placebo (N=10) was administered twice daily to patients with APDS. Demographics of the patients who participated in this study are summarized in Clinical Studies [see Clinical Studies ( 14 )] . Table 1 presents the number of patients and incidence, rounded to the nearest percent, of adverse reactions that occurred in 2 or more patients treated with JOENJA and for which the incidence in patients treated with JOENJA was greater than the incidence in patients treated with placebo. The most common adverse reactions (> 10%) were headache, sinusitis, and atopic dermatitis. Table 1 Adverse Reactions Reported by 2 or More JOENJA-Treated Patients and More Frequently than Placebo Adverse Reactions JOENJA N=21 n (%) Placebo N=10 n (%) 1 Dermatitis atopic: including dermatitis atopic and eczema 2 Tachycardia: including tachycardia and sinus tachycardia Headache 5 (24) 2 (20) Sinusitis 4 (19) 0 Dermatitis atopic 1 3 (14) 0 Tachycardia 2 2 (10) 0 Diarrhea 2 (10) 0 Fatigue 2 (10) 1 (10) Pyrexia 2 (10) 0 Back pain 2 (10) 0 Neck pain 2 (10) 0 Alopecia 2 (10) 0 Specific Adverse Reactions Laboratory Abnormalities Seven (33%) patients receiving JOENJA developed an absolute neutrophil count (ANC) between 500 and 1500 cells/microL. No patients developed an ANC < 500 cells/microL and there were no reports of infection associated with neutropenia. Weight Increase In the open-label clinical trial (n=37), five patients (14%) experienced weight gain. Some patients became overweight or obese. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of JOENJA. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Immune System Disorders : hypersensitivity (anaphylaxis)
Drug Interactions
7 DRUG INTERACTIONS Strong CYP3A4 Inhibitors: Avoid concomitant use. ( 7.1 ) Strong and Moderate CYP3A4 Inducers: Avoid concomitant use. ( 7.1 ) BCRP, OATP1B1, and OATP1B3 Substrates: Avoid concomitant use. ( 7.2 ) 7.1 Effects of Other Drugs on JOENJA Strong CYP3A4 Inhibitors Concomitant use of JOENJA with strong CYP3A4 inhibitors should be avoided. JOENJA is a substrate of CYP3A4. Leniolisib exposure was increased 2-fold when co-administered with itraconazole, a strong CYP3A4 inhibitor [see Clinical Pharmacology ( 12.3 )] . Strong and Moderate CYP3A4 Inducers Concomitant use of JOENJA with strong and moderate CYP3A4 inducers should be avoided. JOENJA is a substrate of CYP3A4. Concomitant use of strong and moderate CYP3A4 inducers may result in reduced leniolisib exposure and thus reduced leniolisib efficacy [see Clinical Pharmacology ( 12.3 )] . 7.2 Effects of JOENJA on Other Drugs BCRP, OATP1B1, and OATP1B3 Substrates Concomitant use of JOENJA with BCRP, OATP1B1, and OATP1B3 substrates should be avoided. JOENJA is an inhibitor of BCRP, OATP1B1, and OATP1B3 transporters. Administration of JOENJA increases exposure of BCRP, OATP1B1, and OATP1B3 substrates [see Clinical Pharmacology (12.3) ] , which may increase the risk of adverse reactions related to these substrates.

Pregnancy and Breastfeeding
8.1 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 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...
Overdosage
10 OVERDOSAGE If overdosage occurs, monitor the patient for any signs or symptoms of adverse reactions. Treatment of overdose with JOENJA consists of general supportive measures including monitoring of vital signs as well as observation of the clinical status of the patient.
