ZURICH, SWITZERLAND / ACCESSWIRE / January 10, 2023 / NLS Pharmaceutics Ltd. (Nasdaq:NLSP, NLSPW) ("NLS" or the "Company"), a Swiss clinical-stage biopharmaceutical company focused on the discovery and development of innovative therapies for patients with rare and complex central nervous system disorders, today announced that the Patents Registry, Intellectual Property Department of The Government of the Hong Kong Special Administrative Region has granted approval for Patent Application 42022055879.5, which covers Mazindol ER as a method of treatment for ADHD. This patent is expected to expire no earlier than 2037.

"This patent grant reinforces our continued effort to build our global franchise with Mazindol ER," said Alex Zwyer, Chief Executive Officer of NLS Pharmaceutics. "Along with our Orphan Drug Designations in both the U.S. and Europe, we are pleased to obtain patent coverage in another major market for our proprietary formulation of Mazindol ER and believe that our proprietary position is strong."

Mazindol is not currently available in Hong Kong and has not yet been promoted for use in ADHD. Quilience® (Mazindol ER), the Company's lead product candidate and proprietary extended-release formulation of Mazindol (Mazindol ER), is being developed for the treatment of narcolepsy, and potentially other sleep-wake disorders such as IH. Top-line results from our Phase 2a clinical trials evaluating Mazindol ER, in the treatment of ADHD as well as narcolepsy, resulted in positive favorable results, meeting the primary endpoint with high statistical significance.

ADHD is one of the most common childhood psychiatric disorders, with symptoms including inattention, impulsivity, and hyperactivity. The prevalence of ADHD among children and adolescents in Hong Kong and Mainland China are estimated to be 6.4% and 6.5% respectively. According to Market Data Forecast®, the global ADHD therapeutics market is valued at more than $29 billion currently and is projected to grow to nearly $45 billion by 2037.

About Quilience^®

The Company's lead product candidate, Quilience^®, is a proprietary extended-release formulation of Mazindol (Mazindol ER) and is being developed for the treatment of narcolepsy, and potentially other sleep-wake disorders such as IH, for which NLS recently obtained Orphan Disease Designation (ODD) from the U. S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA). Mazindol is a triple monoamine reuptake inhibitor and partial Orexin-2 Receptor agonist, which was used for many years to treat patients diagnosed with narcolepsy in compassionate use programs. A Phase 2 multi-center U.S. clinical study evaluating Quilience^® in adult patients suffering from narcolepsy met its primary endpoint with high statistical significance and demonstrated a favorable safety and tolerability profile. NLS also successfully completed a Phase 2 study in the U.S. evaluating Nolazol^® (Mazindol Controlled-Release) in adult patients suffering from ADHD. The study met all primary and secondary endpoints and Nolazol^® was well-tolerated. Quilience^® has received Orphan Drug Designations both in the U.S. and in Europe for the treatment of narcolepsy. Up to 1/3 of narcoleptic patients are also diagnosed with ADHD.
