• Key patent now granted in major markets including the U.S., Europe, Canada & South Korea
• Patent claims cover use of the Company’s lead product candidate, Quilience® (mazindol ER) in both attention deficit hyperactivity disorder (ADHD) & narcolepsy

STANS, SWITZERLAND / ACCESSWIRE / January 4, 2022 / NLS Pharmaceutics Ltd. (NASDAQ:NLSP)(NASDAQ:NLSPW) (“NLS” or the “Company”), a Swiss clinical-stage pharmaceutical company focused on the discovery and development of innovative therapies for patients with rare and complex central nervous system disorders, announces that the United States Patent and Trademark Office (USPTO) has granted the Company U.S. Patent No. 11207271, entitled A MAZINDOL IR/SR MULTILAYER TABLET AND ITS USE FOR THE TREATMENT OF ATTENTION DEFICIT/HYPERACTIVITY DISORDER (ADHD). The patent covers oral formulations containing immediate-release and sustained-release layers of mazindol and their use in treating attention deficit disorders (ADD or ADHD), related deficit of alertness or decline of vigilance, or excessive daytime sleepiness including narcolepsy or idiopathic hypersomnia.

“Our intellectual property estate has been significantly strengthened since our initial public offering in February 2021, putting NLS in a solid position as we anticipate reporting Phase 2a results for Quilience® (mazindol ER) to treat narcolepsy in the first quarter of 2022,” said Alex Zwyer, Chief Executive Officer of NLS. “We now have issued patents in major markets including the U.S., Europe, Canada, and South Korea covering our extended-release formulation of mazindol. These recently issued patents augment the Orphan Drug Designations that have been granted for Quilience® in both the U.S. and Europe. Most patients with narcolepsy remain unsatisfied with current treatment options, and we believe that Quilience® has potential to fill a major need in the market given mazindol’s history of safety and evidence of effectiveness in treating the symptoms of narcolepsy. We remain focused on bringing this treatment option to patients suffering from narcolepsy and potentially other sleep-wake disorders as soon as possible.”

About NLS Pharmaceutics Ltd.
NLS Pharmaceutics is a Swiss clinical-stage biopharmaceutical company led by an experienced management team with a track record of developing and repurposing product candidates to treat rare and complex central nervous system disorders. 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. 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. NLS has initiated a phase 2 program in the U.S. evaluating Quilience® in adult subjects suffering from narcolepsy. Previously, NLS successfully completed a phase 2 study in the U.S. evaluating Nolazol^® (mazindol controlled-release) in adult subjects 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 one-third of narcoleptic patients are also diagnosed with ADHD.
