Attention-Deficit Hyperactivity Disorder (ADHD) Clinical Trial
Official title:
A Phase II Tolerability and Efficacy Study of PDC-1421 Treatment in Adult Patients With Attention-Deficit Hyperactivity Disorder (ADHD), Part I
The primary objective of this trial was to determine the effective doses and treatment period of PDC-1421 Capsule in subjects with ADHD. The secondary objective was to evaluate the safety of PDC-1421 Capsule in subjects receiving PDC-1421 at various dose levels.
This study was a Part I of Phase II study designed to evaluate the safety and efficacy in adult patients with ADHD. The Screening phase is intended for diagnosing and assessing the patient for possible inclusion in the study and for providing an adequate washout period. The targeted population of this Part I study is six subjects who met the intent-to-treat per-protocol basis. Part I study is an open-label study, single-center, and dose escalation evaluation in six patients. 1. Low dose: Six subjects will be initially evaluated for safety and efficacy assessments at low-dose (1 PDC-1421capsule TID) for 28 days. The subject will return for visit once a week during the treatment period. 2. Checkpoint #1: There will be an evaluation with all safety assessments data to decide whether subjects pass the checkpoint to enter high-dose treatment or continue to receive a low-dose treatment by the investigator. 3. High dose: The subjects who pass Checkpoint #1 will be initially evaluated for safety and efficacy assessments at high-dose (2 PDC-1421 capsules TID) for 28 days. Subjects will return for visit biweekly during the treatment period. 4. Checkpoint #2: There will be an evaluation with all safety assessments data to decide whether this study passes the checkpoint to enter Part II by the investigators. ;
