Primary endpoint: Improvement in ADHD symptoms, vs. placebo, from 8AM to 8PM

TORONTO, Canada I July 29, 2015 I Highland Therapeutics Inc. (“Highland”), a pharmaceutical company, today announced that its wholly owned subsidiary, Ironshore Pharmaceuticals & Development, Inc. (“Ironshore”), has initiated enrolment in a pivotal study to assess the safety and efficacy of HLD-200 – a next-generation formulation of methylphenidate – in children with Attention-Deficit/Hyperactivity Disorder (“ADHD”).

The study, “A Phase 3, Multicenter, Open-label Treatment-optimized, Double-blind, Randomized, Placebo-controlled, Forced-withdrawal, Parallel Group Study to Evaluate the Safety and Efficacy of Evening Dosed HLD200, a Novel Delayed and Extended Release Formulation (DELEXIS) of Methylphenidate Hydrochloride, in Children Aged 6-12 with Attention Deficit Hyperactivity Disorder (ADHD) in a Laboratory Classroom Setting” is expected to generate top-line data by year-end.

“The initiation of this pivotal study, the first of two we anticipate completing over the next six months, is a historic moment for the Company and the result of many years of dedication and passion from the remarkable team we have assembled,” said David Lickrish, Ironshore’s Chief Executive Officer. “We have long believed that our products could change the way ADHD is treated given HLD-200’s potential for (1) control over symptoms during the Early Morning Routine (EMR), (2) a consistent clinical effect throughout the day and (3) an extended duration of effect into the important evening homework period, representing a win-win-win for patients.”

The pivotal trial will enroll approximately 150 pediatric patients between the ages of six and twelve across seven sites in the U.S. The study will utilize an open-label, treatment-optimization Phase, followed by a double-blind, placebo-controlled, 1-week, parallel-group study design to assess safety and tolerability as well as the time-course of treatment effect of evening-dosed HLD-200 in pediatric subjects diagnosed with ADHD. The study has been designed to build upon the successful results of the exploratory Phase 3 trial, known as CEES (Clinical Endpoint Evaluation Study), which was completed in 2014.

The primary objective of the study is to assess whether prior-evening treatment with HLD-200 improves control of ADHD symptoms, compared with placebo, from 8:00am to 8:00pm in pediatric subjects with ADHD.

Commenting on the pivotal study, Dr. Randy Sallee, Ironshore’s Chief Medical Officer said, “Impaired functioning during the morning routine as a result of uncontrolled ADHD symptoms is an important unmet medical need for which no practical solution exists today. The initiation of this study brings us one step closer to reaching one of Ironshore’s founding objectives – to provide such a solution. Should we also demonstrate an extended duration of effect, we believe HLD-200 could represent a first-line therapy in ADHD, potentially covering the ‘bookends’ of the patient’s day – from early morning to evening homework time. The results of this study, in conjunction with those of a second pivotal study we expect to initiate shortly, if successful, would provide Ironshore with a robust clinical package to submit as part of a New Drug Application in mid-2016.”
