Duration and Efficacy of Azstarys on Adult ADHD Symptoms and Executive Function in Early Evening
Study Details
Study Description
Brief Summary
One purpose of this trial is to extend the safety and efficacy evidence basis for Azstarys in adults with ADHD. This open-label, treatment study will examine the efficacy of Azstarys on ADHD symptoms using the AISRS 18-item total score on the AISRS-expanded; the Adult ADHD Investigator Symptom Rating Scale. The investigators will also examine Executive Function later in the day (early evening, about 12 hours after first morning dosing).

|---|---|
| Experimental: Adult ADHD Patients Enrolled participants will begin with a two-week observation stabilization before starting treatment with Azstarys. Participants found to have ≥30% change in their total Adult ADHD Investigator Symptom Rating Scale (AISRS) scores during the two-week observation stabilization period treatment will be discontinued from the study. Remaining participants will be dispensed a three-week supply of Azstarys on a weekly basis. |
Drug: Serdexmethylphenidate/dexmethylphenidate
Azstarys capsules for once-daily oral use for three weeks. Flexible dose starting at 39.2 mg serd-mph/7.8 mg d-mph and moving up to 52.3 mg serd-mph/10.4 mg d-mph.

Outcome Measures
Primary Outcome Measures
