Ironshore Pharmaceuticals Announces JORNAY PM™ (METHYLPHENIDATE HCL) CII, the first and only ADHD stimulant dosed in the evenings

Research Triangle Park, NC, June 11, 2019 — Ironshore Pharmaceuticals Inc. (“Ironshore”), a wholly owned subsidiary of Highland Therapeutics Inc. and a leader in the commercialization of novel treatments for Attention Deficit Hyperactivity Disorder (“ADHD”), today announced that JORNAY PM™ (methylphenidate HCl) extended-release capsules CII is now available in the United States. JORNAY PM is a CNS stimulant approved by the U.S. Food and Drug Administration (“FDA”) for the treatment of ADHD in patients 6 years and older. JORNAY PM is the first and only ADHD stimulant medication that is dosed in the evening and helps improve symptoms from the time the patient wakes up the next morning and continues to control symptoms throughout the day. The evening administration of a stimulant medication is made possible by DELEXIS®, Ironshore’s novel drug delivery platform. DELEXIS contains two functional film coatings that act synergistically to achieve a unique pharmacokinetic profile. The first layer delays the initial release of drug for up to 10 hours while the second layer helps to control the rate of release of the active pharmaceutical ingredient throughout the day.

JORNAY PM was well tolerated in clinical trials with a safety profile generally consistent with other methylphenidate products. Based on accumulated data from other methylphenidate products, the most common adverse reactions for pediatric patients and adults are: appetite decreased, insomnia, nausea, vomiting, dyspepsia, abdominal pain, weight decreased, anxiety, dizziness, irritability, affect lability, tachycardia, and blood pressure increased. Additional adverse reactions in pediatric patients 6 to 12 years treated with JORNAY PM: headache, psychomotor hyperactivity, and mood swings. JORNAY PM is the first drug utilizing Ironshore’s proprietary drug delivery platform, DELEXIS, and is available in 20 mg, 40 mg, 60 mg, 80 mg, and 100 mg extended-release capsules.

“The launch of our first commercial product for the treatment of ADHD marks an important milestone in the Company’s history and demonstrates our commitment to developing innovative, patient-centric treatment options for patients with ADHD,” said David Lickrish, Chief Executive Officer of Ironshore Pharmaceuticals & Development Inc. “We are delighted to offer the ADHD community a novel medicine, developed over a 10-year period and supported by nine clinical studies, including two pivotal trials, that works when patients wake up, but does not come at the expense of coverage throughout the day.”

Commenting on the availability of JORNAY PM, Dr. Randy Sallee, Ironshore’s Chief Medical Officer said, “ADHD can adversely impact a patient’s ability to complete their morning routine, prepare for the day, and get out of the house in the morning. As a Board Certified psychiatrist, I believe the therapeutic profile of JORNAY PM, enabled by advanced drug-delivery technology, has the potential to have a profound impact on treatment paradigms in ADHD.”

Results from clinical studies demonstrated that children with ADHD treated with JORNAY PM showed improved symptoms in the early morning that lasted throughout the day. The drug also showed significant improvements in standard tests that measure ADHD symptoms at home and school throughout the day, as well as with new assessment tools that measure difficulties in the early morning, late afternoon and evening.

“Patients with ADHD can have very challenging mornings,” said Dr. Ann Childress, M.D, President, Center for Psychiatry and Behavioral Medicine, Inc. in Las Vegas and Clinical Trial Investigator. “Several families I work with have developed a number of creative, but often disruptive strategies, like waking up extra early to take medicine in an attempt to improve the early morning routine. I believe that JORNAY PM represents a welcome addition to the therapeutic options available to physicians that treat ADHD as well as for families who face ADHD-associated difficulties, not only during the morning routine but throughout the day.”

About Ironshore’s Phase III Clinical Studies

The effectiveness of JORNAY PM was established in two separate Pivotal Phase III, multicenter, randomized, double-blind, placebo-controlled studies conducted in a total of 278 pediatric patients aged 6 to 12 years with a diagnosis of ADHD per DSM-5 criteria. In addition to the traditional scales that assess efficacy in ADHD clinical trials such as the Swanson, Kotkin, Agler, M-Flynn, and Pelham (SKAMP) rating scale and the ADHD Rating Scale (ADHD-RS-IV), Ironshore’s pivotal trials assessed JORNAY PM’s efficacy in the early morning period using the morning subscale of the Parent Rating of Evening and Morning Behavior-Revised scale (PREMB-R AM) and the Before School Functioning Questionnaire (BSFQ).

In Study 1, improvement in ADHD manifestations in a classroom setting was demonstrated by the primary endpoint, an average of all post-dosed SKAMP combined scores measured during a 12-hour period (8:00 AM to 8:00 PM), and improvement in ADHD manifestations in the early morning was demonstrated by the secondary endpoint, PREMB-R AM.

In Study 2, improvement in ADHD manifestations throughout the day was demonstrated by the primary endpoint, ADHD-RS-IV, and improvement in ADHD manifestations before school was demonstrated by the secondary endpoint, the BSFQ, which is intended to assess early morning before school activities from the time the child awakens and some behaviors not specific to early morning.

About ADHD

ADHD is among the most common childhood psychiatric conditions with behavioral symptoms fluctuating throughout the day. It is usually first diagnosed in childhood and often lasts into adulthood. Children with ADHD may have trouble paying attention, controlling impulsive behaviors, or be overly active. Many home-based difficulties for children and adolescents with ADHD occur during the early morning routine (i.e. before the school day begins).
