Open Label Safety Study Shows Improved Sleep for Children With ADHD After One Month of Azstarys

BOSTON, Sept. 21, 2022. Corium, Inc., a fully integrated biopharmaceutical company leading the development and commercialization of novel central nervous system (CNS) therapies, announced publication of a poster, "Serdexmethylphenidate/Dexmethylphenidate Effects on Sleep in Children With Attention-Deficit Hyperactivity Disorder," at the Psych Congress 2022 in New Orleans. The poster presented an analysis of the twelve-month open label safety study in children ages 6-12 using Azstarys (serdexmethylphenidate [SDX] and dexmethylphenidate [d-MPH]), which is indicated for the treatment of attention-deficit hyperactivity disorder (ADHD) in patients six and older. The data showed that the children, after one month of taking AZSTARYS, had statistically significant improvement in their sleep as assessed by the Children's Sleep Habits Questionnaire (CSHQ). The improvement in sleep was sustained through 12 months of treatment with Azstarys .

Azstarys, a central nervous system (CNS) stimulant designated a Schedule II controlled substance, is the first and only medicine for ADHD symptoms containing SDX, the prodrug of d-MPH, along with immediate-release d-MPH. SDX is designed specifically to be pharmacologically inactive until reaching a patient's lower gastrointestinal (GI) tract, where, by design, the prodrug gradually converts to d-MPH throughout the day. This formulation provides control of ADHD symptoms rapidly with the immediate-release d-MPH and for an extended duration with SDX. Once-daily Azstarys is available in the U.S. in three SDX/d-MPH dose strengths of 26.1/5.2 mg, 39.2/7.8 mg, and 52.3/10.4 mg. The SDX component of Azstarys is designated a Schedule IV controlled substance.

"Sleep-related problems are common in children with ADHD, which some stimulant medications can negatively impact. The positive study data reported provide important and relevant information to healthcare professionals considering Azstarys," said Greg W. Mattingly, lead author of the poster, associate clinical professor of psychiatry at Washington University School of Medicine, and president elect of the American Professional Society for ADHD and Related Disorders.

About the Open Label Safety Trial
This one-year dose-optimized open-label study (NCT03460652) enrolled 282 children aged 6 to 12 years at 19 locations in the U.S. The participants included 70 children who participated within the previous 45 days in a prior double-blind Azstarys classroom study (NCT03292952) and 212 new children. After a 30-day screening phase and a three-week dose-optimization phase for new participants, the children received treatment with Azstarys for one year. Optimized Azstarys doses included 26.1/5.2 milligrams (mg), 39.2/7.8 mg, or 52.3/10.4 mg of SDX/d-MPH daily, which delivered 20-, 30-, and 40-mg molar equivalent doses of total d-MPH HCl. The Children's Sleep Habits Questionnaire (CSHQ) was a pre-specified secondary endpoint that evaluated sleep parameters. The sleep assessment included data from 238 children.

After one month of Azstarys treatment in the open-label classroom study, the children's total average sleep disturbance score on the CSHQ significantly decreased, indicating overall improvements in their sleep behavior. Specifically, their scores decreased from 53.4 (±5.9 standard deviation [SD]) at the study start to 50.5 (±5.4) at one month, a least-squares mean change from baseline of −2.9 points (95% CI: −3.5 to −2.4; P < .0001). Moreover, their total mean CSHQ scores remained in a range of 48.9 to 50.1 points for up to 12 months, indicating sustained overall sleep improvement from baseline.

About ADHD
Attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopment disorder marked by an ongoing pattern of inability to pay attention or hyperactivity with impulsive behaviors or both, which interferes with functioning or development. ADHD usually is diagnosed during childhood but often continues into adulthood. Children with ADHD may have trouble paying attention, controlling impulsive behaviors (may act without thinking about what the result will be), or be overly active. In the United States, an estimated 6.1 million children have received an ADHD diagnosis, including 2.4 million aged 6 to 11 years.

Azstarys is a central nervous system (CNS) stimulant indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in patients aged 6 years and older.
