HETLIOZ can potentially impair the performance of activities requiring complete mental alertness. 6 ADVERSE REACTIONS 3 Reference ID: 4709960 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 clinical practice. More than 2080 subjects have been treated with at least one dose of HETLIOZ, of which more than 380 have been treated for > 26 weeks and more than 170 have been treated for > 1 year. Non-24-Hour Sleep-Wake Disorder (Non-24) A 26-week, parallel-arm placebo-controlled study (Study 1) evaluated HETLIOZ (n=42) compared to placebo (n=42) in patients with Non-24. A randomized-withdrawal, placebo- controlled study of 8 weeks duration (Study 2) also evaluated HETLIOZ (n=10), compared to placebo (n=10), in patients with Non-24. In placebo-controlled studies, 6% of patients exposed to HETLIOZ discontinued treatment due to an adverse event, compared with 4% of patients who received placebo. Table 2 shows the incidence of adverse reactions from Study 1. Table 2: Adverse Reactions in Study 1 HETLIOZ Placebo N=42 N=42 Headache 17 % 7 % Alanine aminotransferase increased 10 % 5 % Nightmare/abnormal dreams 10 % 0 % Upper respiratory tract infection 7 % 0 % Urinary tract infection 7 % 2 % *Adverse reactions with an incidence > 5% and at least twice as high on HETLIOZ than on placebo are displayed. Nighttime Sleep Disturbances in Smith-Magenis Syndrome (SMS) A 9-week, double-blind, randomized, placebo-controlled, two-period crossover study evaluated HETLIOZ (capsules and oral suspension; n=25) compared to placebo (n=26) in the treatment of nighttime sleep disturbances in patients with Smith-Magenis Syndrome. Pediatric patients (n=11, age 3 to 15 years) received HETLIOZ LQ oral suspension, and patients ≥16 years of age (n=14) received HETLIOZ capsules. Adverse reactions were similar in patients treated for Non-24 and patients with Smith-Magenis syndrome treated for nighttime sleep disturbances.
