The safety of QUVIVIQ was evaluated in three placebo-controlled clinical studies (two 3-month studies of identical design [Study 1 and Study 2], and a 9-month extension study [Study 3]). Study 1 evaluated 50 mg and 25 mg doses of QUVIVIQ, while Study 2 evaluated a 25 mg dose and a 10 mg dose of QUVIVIQ. The 10 mg dose is not an approved dose. A total of 1232 patients (including approximately 40% elderly patients [≥ 65 years old]), received QUVIVIQ 50 mg (N = 308); 25 mg (N = 618); or 10 mg (an unapproved dose) (N = 306). A total of 576 patients were treated with QUVIVIQ for at least 6 months and 331 for at least 12 months. Most Common Adverse Reactions The most common reported adverse reaction (in at least 5% of patients and greater than placebo) during double-blind treatment in Study 1 was headache. Table 1 shows adverse reactions that occurred in at least 2% of patients treated with QUVIVIQ and more frequently than in patients who received placebo in Study 1. Table 1 Adverse Reactions Reported in ≥ 2% of QUVIVIQ-treated Patients and Greater than in Placebo-treated Patients in a 3-Month Placebo-Controlled Study (Study 1) QUVIVIQ QUVIVIQ Placebo 25 mg 50 mg (N=310) (N=308) (N=309) % % % Nervous System Disorders Headache The following terms were combined: Headache includes: headache, tension headache, migraine, migraine with aura, head discomfort Somnolence or fatigue includes: somnolence, sedation, fatigue, hypersomnia, lethargy Dizziness includes: dizziness, vertigo, labyrinthitis Nausea includes: nausea, vomiting, procedural nausea 6 7 5 Somnolence or fatigue 6 5 4 Dizziness 2 3 2 Gastro-intestinal disorders Nausea 0 3 2 Other Adverse Reactions Observed During Clinical Trials (Study 1 and Study 2) Other adverse reactions of < 2% frequency but greater than placebo are shown below. The following do not include adverse reactions 1) for which a drug cause was remote, 2) that were so general as to be uninformative, or 3) that were not considered to have clinically significant implications. Sleep paralysis was reported in 0.5% and 0.3% of patients receiving QUVIVIQ 25 mg and 50 mg, respectively, compared to no reports for placebo. Hypnagogic and hypnopompic hallucinations were reported in 0.6% of patients receiving QUVIVIQ 25 mg compared to no cases with QUVIVIQ 50 mg or placebo. 6.2 Post-Marketing Experience The following adverse reactions have been identified during post-approval use of QUVIVIQ. 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. Psychiatric disorders : Nightmares or abnormal dreams Immune system disorders: Hypersensitivity (including angioedema, rash, urticaria)
Drug Interactions
7 DRUG INTERACTIONS Strong CYP3A4 inhibitors: Avoid concomitant use. ( 2.2 , 7.1 ) Moderate CYP3A4 inhibitors: Maximum recommended dose is 25 mg. ( 2.2 , 7.1 ) Moderate or Strong CYP3A4 inducers: Avoid concomitant use. ( 7.1 ) 7.1 Effects of Other Drugs on QUVIVIQ Table 2 describes clinically significant drug interactions where the concomitant use of other drugs affects QUVIVIQ. Table 2 Effects of Other Drugs on QUVIVIQ Strong or Moderate CYP3A4 Inhibitors Clinical Implications: Concomitant use with a strong or moderate CYP3A4 inhibitor increases exposure to daridorexant [see Clinical Pharmacology (12.3) ] , which may increase the risk of QUVIVIQ adverse reactions. Prevention or Management: The recommended dose of QUVIVIQ is 25 mg when used with a moderate CYP3A4 inhibitor [see Dosage and Administration (2.2) ] . Concomitant use of QUVIVIQ with a strong inhibitor of CYP3A4 is not recommended [see Dosage and Administration (2.2) ] . Strong and Moderate CYP3A4 Inducers Clinical Implications: Concomitant use with a strong or moderate CYP3A4 inducer decreases exposure to daridorexant [see Clinical Pharmacology (12.3) ] , which may reduce the efficacy of QUVIVIQ. Prevention or Management: Concomitant use of QUVIVIQ with a strong or moderate inducer of CYP3A4 is not recommended [see Dosage and Administration (2.2) ] . Alcohol and Other CNS Depressants Clinical Implications: Concomitant use of alcohol or other CNS depressants with QUVIVIQ may lead to additive impairment of psychomotor performance and risk of CNS depression [see Clinical Pharmacology (12.2) ] . Prevention or Management: Avoid alcohol consumption with QUVIVIQ [see Warnings and Precautions (5.1) ] . Use with caution in patients receiving CNS depressants. Consider dose adjustment of QUVIVIQ and/or the CNS depressant(s) if used concomitantly [see Warnings and Precautions (5.1) ] . 7.2 Effects of QUVIVIQ on Other Drugs Table 3 describes clinically significant drug interactions where the concomitant use of QUVIVIQ affects other drugs. Table 3 Effects of QUVIVIQ on Other Drugs CYP3A4 Substrates Clinical Implications: Concomitant use of QUVIVIQ with CYP3A4 substrates increases the exposure to CYP3A4 substrate [see Clinical Pharmacology (12.3) ] . Prevention or Management: Use with caution in patients receiving CYP3A4 substrates with narrow therapeutic index. P-gp Substrates Clinical Implications: Concomitant use of QUVIVIQ with P-gp substrates increases the exposure to P-gp substrate [see Clinical Pharmacology (12.3) ] . Prevention or Management: Use with caution in patients receiving P-gp substrates with a narrow therapeutic index.

Pregnancy and Breastfeeding
8.1 Pregnancy Pregnancy Exposure Registry There will be a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to QUVIVIQ during pregnancy. Pregnant women exposed to QUVIVIQ and healthcare providers are encouraged to call Idorsia Pharmaceuticals Ltd at 1-833-400-9611. Risk Summary There are no available data on QUVIVIQ use in pregnant women to evaluate for drug-associated risks of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. In animal reproduction studies, oral administration of daridorexant to pregnant rats and rabbits during the period of organogenesis did not cause fetal toxicity or malformation at doses up to 8 and 10 times the maximum recommended human dose (MRHD) of 50 mg, respectively, based on AUC. Oral administration of daridorexant to pregnant and lactating rats did not cause any maternal or developmental toxicity at doses up to 9 times the MRHD, based on AUC (see Data ) . 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 in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data Daridorexant was administered orally to pregnant rats during the period of organogenesis at doses of 30, 100, and 300 mg/kg/day, which are approximately 1, 3, and 8 times the MRHD of 50 mg, respectively, based on AUC. Daridorexant did not cause any maternal or embryofetal toxicities or fetal malformation at doses up to 300 mg/kg/day. The NOAEL for maternal and fetal toxicity is 300 mg/kg/day, which is approximately 8 times the MRHD of 50 mg, based on AUC. Daridorexant was administered orally to pregnant rabbits during the period of organogenesis at doses of 30, 60, and 120 mg/kg/day, which are approximately 3, 4, and 10 times the MRHD of 50...
Overdosage
10 OVERDOSAGE There is limited clinical experience with QUVIVIQ overdose. In clinical pharmacology studies, healthy subjects were administered single doses of up to 200 mg (4 times the maximum recommended dose) of QUVIVIQ. The following adverse reactions were observed: somnolence, muscle weakness, cataplexy-like symptoms, sleep paralysis, disturbance in attention, fatigue, headache, and constipation. There is no specific antidote to an overdosage of QUVIVIQ. In the event of an overdose, general symptomatic and supportive medical care, along with immediate gastric lavage where appropriate, should be provided and patients should be carefully monitored. Dialysis is unlikely to be effective as daridorexant is highly protein bound. Consider contacting the Poison Help Line (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendations.
