KemPharm Announces Research Involving AZSTARYS® and Serdexmethylphenidate to be Featured in Poster Presentations at Multiple Medical Conferences during ADHD Awareness Month (October)
CELEBRATION, Fla., Oct. 20, 2021 (GLOBE NEWSWIRE) -- (NASDAQ: KMPH), a specialty pharmaceutical company focused on the discovery and development of proprietary prodrugs, today announced that research involving AZSTARYS® and serdexmethylphenidate (SDX), the company’s proprietary prodrug of d-methylphenidate (d-MPH), will be featured in poster presentations during multiple medical conferences being held in October (ADHD Awareness Month). Presentations will be given at the following conferences:
| Event: | American Academy of Child & Adolescent Psychiatry 68th Annual Meeting (AACAP 2021) |
| Date: | October 18-30, 2021 |
| Title: | Single-Dose Pharmacokinetics of Serdexmethylphenidate/d-Methylphenidate Capsules in Children and Adolescents with ADHD and Healthy Adults: An Evaluation of Age and Body Weight |
| Event: | Psych Congress |
| Date: | October 29-November 1, 2021 |
| Title: | Steady-State Pharmacokinetics and Relative Bioavailability of Serdexmethylphenidate/d-Methylphenidate, a Treatment for Attention-Deficit/Hyperactivity Disorder, Containing a Novel Prodrug of d-Methylphenidate |
During AACAP 2021, Rene A. Braeckman, Ph.D., Vice President, Clinical Development for KemPharm, will present the poster titled, “Single-Dose Pharmacokinetics of Serdexmethylphenidate/d-Methylphenidate Capsules in Children and Adolescents with ADHD and Healthy Adults: An Evaluation of Age and Body Weight,” which highlights data from two Phase 1 clinical trials evaluating the pharmacokinetic (PK) properties of single doses of AZSTARYS administered to children, adolescents, and adults. Researchers demonstrated that the shape of the PK curves in children and adolescents was similar to that in adults. Consistent with published studies of methylphenidate PK, exposure of d-MPH decreased with age due to body weight differences between younger children and adolescents. However, when normalized by dose and body weight, d-MPH exposure levels and PK parameters were comparable between children, adolescents, and adults. Researchers concluded that body weight rather than age is the appropriate scaling factor for d-MPH exposure levels after AZSTARYS dosing in children and adolescents.
“We are pleased that clinical research involving AZSTARYS and SDX have been accepted for poster presentations during multiple medical conferences in October, coinciding with ADHD Awareness Month,” said Travis Mickle, Ph.D., President and CEO of KemPharm. “Our goal in developing AZSTARYS was to advance the treatment of ADHD by bringing to market a product that could address several key shortcomings of other commercially available ADHD drugs. The data being presented at these conferences highlights several properties of AZSTARYS and SDX that, we believe, will be attractive to patients and prescribers who have been seeking innovative therapies that address the symptoms of ADHD, while also reducing the side-effects sometimes encountered with stimulant-based medications.”
About Attention Deficit Hyperactivity Disorder (ADHD):
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common mental disorders affecting children. ADHD also affects many adults. Symptoms of ADHD include inattention (not being able to keep focus), hyperactivity (excess movement that is not fitting to the setting) and impulsivity (hasty acts that occur in the moment without thought).1 An estimated 8.4% of children and 2.5% of adults have ADHD.23
The U.S. ADHD market accounted for approximately $17.5 billion of revenue in 2019 with a year-over-year prescription growth rate greater than four percent (4%). Within this, the branded portion of the ADHD market was approximately $7.4 billion in 2019, with extended-release products representing more than 95% of the branded prescriptions. In 2019, the methylphenidate segment of the ADHD market accounted for approximately 20 million prescriptions and $4.9 billion in sales.
