FDA approves Mydayis – a once-daily option for ADHD symptom control in patients 13 years plus

Mydayis demonstrated improvements lasting up to 16 hours post-dose, beginning at 2 or 4 hours post-administration, compared with placebo, in total score on a skill-adjusted math test that measures attention in ADHD.

The FDA approval of Mydayis is based on results from 16 clinical studies evaluating Mydayis in more than 1,600 subjects, including adolescents (aged 13-17 years) and adults with ADHD. In pivotal, placebo-controlled clinical studies, Mydayis significantly improved symptoms of ADHD, as measured by the ADHD-RS-IV and the Permanent Product Measure of Performance (PERMP), in adults and adolescents. Improvement on the PERMP, an objective, validated, skill-adjusted math test that measures attention in ADHD patients, reached statistical significance beginning at 2 or 4 hours post-dose and lasting up to 16 hours post-dose.

“Mydayis is the latest innovation in Shire’s 20-year legacy of helping to support the treatment of ADHD. It’s a testament to Shire’s commitment to helping support the evolving needs of appropriate patients with ADHD,” said Flemming Ornskov, CEO of Shire. “With this approval, we hope to help patients who need a once-daily treatment option. Mydayis has shown efficacy lasting up to 16 hours after taking one capsule, beginning at 2 or 4 hours post-dose.”

Andrew J. Cutler, Executive Vice President and Chief Medical Officer at Meridien Research and an investigator in the Mydayis clinical trials said: “Many of my patients living with ADHD are trying to manage symptoms that impact them in different settings – often across home life, school or work, and in social settings. Patients have individual needs and may respond differently to treatments, so it is important for healthcare professionals to have multiple options. It’s rewarding to work with Shire to provide a new treatment option that may help appropriate patients with ADHD.”
