RESEARCH TRIANGLE PARK, N.C.--(BUSINESS WIRE)--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 it is presenting a poster featuring a post-hoc analysis of a Phase 3 trial of children with ADHD comparing the optimized dose JORNAY PM® (Methylphenidate HCl) to the study participants’ prior stable stimulant doses. The dose ranges for JORNAY PM were much higher than prior stimulant doses, with dose conversion ratios ranging from 1.8 to 6.0 while the adverse event profile for JORNAY PM was consistent with other methylphenidate formulations. The data presented in the poster may help guide clinicians to target an appropriate dose range of JORNAY PM extended-release capsules CII, which was approved in August 2018 by the U.S. Food and Drug Administration (FDA) for the treatment of ADHD in patients 6 years and older.
The poster and a video presentation are available for viewing at the American Society of Clinical Psychopharmacology (“ASCP”) virtual scientific poster session at https://www.psychiatrist.com/education/Pages/postersession/poster.aspx?p=2. This initiative was coordinated in response to the COVID-19 pandemic and is designed to fill the void in the presentation and dissemination of emerging science historically presented during live meetings.

“Ironshore is proud to participate in ASCP’s innovative new forum to present data and dose conversion ratios that may help guide physicians to target an appropriate dose range when switching patients from previous ADHD medications to JORNAY PM” said Dr. Randy Sallee, Ironshore’s Chief Medical Officer. “JORNAY PM is the first stimulant treatment for ADHD that leverages the DELEXIS® delayed-release, extended-release, drug delivery technology. In this analysis, the dose conversion ratios between JORNAY PM and prior stimulants were higher than what would be expected. The bioavailability of JORNAY PM is only 73.9% of immediate-release methylphenidate. The higher JORNAY PM optimized doses can be explained by the lower bioavailability plus JORNAY PM’s absorption profile that is enabled by the DELEXIS drug delivery technology.”
Dr. Bev Incledon, EVP, Research & Development for Ironshore Pharmaceuticals & Development, Inc. added, “Head-to-head studies assessing safety and efficacy of JORNAY PM and other stimulants have not been conducted. This post-hoc analysis demonstrates why JORNAY PM is not substitutable with other methylphenidate products on a milligram per milligram basis; for example, the optimized JORNAY PM dose at 69.2 mg is double the mean prior dose of OROS methylphenidate at 38.1mg. The higher optimized doses of JORNAY PM can be directly attributable to the site of release and absorption for JORNAY PM, the colon. Drug absorption after JORNAY PM dosing is extended over a long duration likely due to the different absorption qualities of the colon relative to the stomach and upper intestine. The unique absorption profile of JORNAY PM enables a dose-dependent duration of effect that extends methylphenidate absorption from the time of awakening into the evening.”
JORNAY PM is the first and only stimulant medication that is dosed in the evening and has demonstrated improved ADHD symptom control in the early morning, throughout the day and during the evening time period in two pivotal Phase 3 trials.

JORNAY PM is the first product to leverage the novel DELEXIS® delayed-release and extended-release drug delivery technology that contains two functional film coatings. 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 from the time the patient awakens the next morning, throughout the day and into the evening.
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).
About JORNAY PM
Developed by Ironshore Pharmaceuticals & Development, Inc., JORNAY PM is a central nervous system (CNS) stimulant prescription medicine used for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in people six years of age and older. JORNAY PM may help increase attention and decrease impulsiveness and hyperactivity in people six years of age and older with ADHD. It is not known if JORNAY PM is safe and effective in children under six years of age.
JORNAY PM is dosed once daily in the evening and should be initiated at 8:00 p.m. Timing of administration of JORNAY PM may be adjusted between 6:30 p.m. and 9:30 p.m. to optimize the tolerability and the efficacy the next morning and throughout the day. The recommended starting dose for patients 6 years and older is 20 mg once daily in the evening. Dosage may be titrated weekly in increments of 20 mg per day up to maximum daily dose of 100 mg. The mean optimized dose required to improve symptoms from the time the patient wakes up, throughout the day and into the evening in children 6-12 years old was 67 mg in Study 1 and 68.1 mg in Study 2. The relative bioavailability of JORNAY PM (given once a day) compared to the same daily dose of a methylphenidate immediate-release oral product (given 3 times a day) in adults is approximately 74%. JORNAY PM is primarily absorbed in the colon which may contribute to the reduced bioavailability of the drug. JORNAY PM is not interchangeable on a milligram-per-milligram basis with other methylphenidate formulations.

IMPORTANT SAFETY INFORMATION
WARNING: ABUSE AND DEPENDENCE
CNS stimulants, including JORNAY PM, other methylphenidate-containing products, and amphetamines, have a high potential for abuse and dependence. Assess the risk of abuse prior to prescribing and monitor for signs of abuse and dependence while on therapy.
CONTRAINDICATIONS
- Known hypersensitivity to methylphenidate or other components of JORNAY PM. Hypersensitivity reactions such as angioedema and anaphylactic reactions have been reported in patients treated with methylphenidate products.
- Concurrent treatment with a monoamine oxidase inhibitor (MAOI), or use of an MAOI within the preceding 14 days because of the risk of hypertensive crisis.
WARNINGS AND PRECAUTIONS
- Serious Cardiovascular Reactions: Sudden death, stroke, and myocardial infarction have been reported in adults treated with CNS stimulants at recommended doses. Sudden death has been reported in pediatric patients with structural cardiac abnormalities and other serious heart problems taking CNS stimulants at recommended doses for ADHD. Avoid use in patients with known structural cardiac abnormalities, cardiomyopathy, serious heart arrhythmias, coronary artery disease, and other serious cardiac problems.
- Blood Pressure and Heart Rate Increases: CNS stimulants may cause an increase in blood pressure and heart rate. Monitor all patients for hypertension and tachycardia.
- Psychiatric Adverse Reactions: CNS stimulants may exacerbate symptoms of behavior disturbance and thought disorder in patients with a pre-existing psychiatric disorder and may induce a manic or mixed episode in patients with bipolar disorder. In patients with no prior history of psychotic illness or mania, CNS stimulants, at recommended doses, may cause psychotic or manic symptoms.
- Priapism: Prolonged and painful erections, sometimes requiring intervention, have been reported with methylphenidate products in both pediatric and adult patients. Priapism has also appeared during a period of drug withdrawal. Immediate medical attention should be sought if signs or symptoms of prolonged penile erections or priapism are observed.
- Peripheral Vasculopathy, including Raynaud’s Phenomenon:CNS stimulants used to treat ADHD are associated with peripheral vasculopathy, including Raynaud’s phenomenon. Careful observation for digital changes is necessary during treatment with ADHD stimulants.
- Long-Term Suppression of Growth: CNS stimulants have been associated with weight loss and slowing of growth rate in pediatric patients. Monitor height and weight at appropriate intervals in pediatric patients.
ADVERSE REACTIONS
- Based on accumulated data from other methylphenidate products, the most common (>5% and twice the rate of placebo) 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 (≥5% and twice the rate of placebo) in pediatric patients 6 to 12 years treated with JORNAY PM: headache, psychomotor hyperactivity, and mood swings.
PREGNANCY AND LACTATION
- CNS stimulant medications, such as JORNAY PM, can cause vasoconstriction and thereby decrease placental perfusion.
- The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for JORNAY PM and any potential adverse effects on the breastfed infant from JORNAY PM or from the underlying maternal condition. Monitor breastfeeding infants for adverse reactions, such as agitation, insomnia, anorexia, and reduced weight gain.
