About the Phase 2a trial (NLS-1021)

NLS-1021 is a multi-center, randomized, prospective Phase 2a clinical trial evaluating Quilience® (mazindol extended release or "ER") as a once-daily monotherapy for the treatment of EDS and cataplexy, the primary symptoms of narcolepsy. The trial was designed to enroll 60 patients diagnosed with NT1 or NT2 to receive treatment with either Quilience® 3mg once daily for 28 days, or placebo. A total of 67 patients were enrolled and randomized 1:1 into each treatment arm. The primary endpoint of the trial is the change from baseline in EDS as measured by the Epworth Sleepiness Scale (ESS), and a key secondary endpoint is the change from baseline in mean weekly number of cataplexy attacks in the subset of patients with cataplexy. Patients completing the 4-week clinical study period were eligible to enroll in an open label extension study (NLS-1022), where each patient was given the option to receive Quilience® monotherapy for up to an additional 6 months.

About NLS Pharmaceutics Ltd.

NLS Pharmaceutics Ltd. 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, and potentially other sleep-wake disorders such as idiopathic hypersomnia (IH), for which NLS recently obtained Orphan Disease Designation (ODD) from 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 2a multi-center U.S. clinical trial evaluating Quilience^® in adult subjects suffering from narcolepsy has been completed, with top-line results expected to be reported in the third quarter of 2022. 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 1/3 of narcoleptic patients are also diagnosed with ADHD.
