Patients in the OLE study (both NT1 and NT2) remain on Quilience monotherapy, without any additional background stimulant, wake promoting nor anti-cataplectic treatment, with several on therapy for over 5 months

ZURICH, SWITZERLAND / ACCESSWIRE / May 4, 2022 / 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, announces that 90% of the 60 patients required to complete its Phase 2a clinical trial for Quilience (Mazindol ER) have been randomized and the Company continues to expect to report final results from this ground-breaking trial by mid-Q3 2022.

NLS Pharmaceutics AG, Wednesday, May 4, 2022, Press release picture

"Since our initial public offering in February 2021, the Company has executed on all of its initiatives including commencing, and rapidly conducting, the first prospective clinical trial evaluating Mazindol ER in patients diagnosed with both narcolepsy type 1 and type 2," said Alex Zwyer, Chief Executive Officer of NLS Pharmaceutics. "Based on the positive interim results that we reported at the World Sleep Congress in March in Rome, with a potential class-leading ESS reduction of 7.3 points and favorable interim safety and tolerability results, we believe that physicians and their patients with narcolepsy are even more enthusiastic to participate in our Phase 2 trial to access our novel Mazindol ER formulation (U.S. and European patent runway until 2037). We eagerly anticipate the final readout from this study and remain on track to deliver the results by the middle of the third quarter of this year. Once the results are reported, if positive, we plan to conduct a post-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) to establish the design of a registration-enabling study. Simultaneously, we continue to work with our financial advisor to evaluate potential strategic partnerships and opportunities to advance the development and anticipated commercialization of Quilience (Mazindol ER)."

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. 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 clinical trial evaluating Quilience in adult subjects suffering from narcolepsy is currently ongoing in the United States. 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. EAPs have great potential to benefit all stakeholders involved, from the patient who receives the medicine early, to the pharmaceutical company who provides it. Although EAPs can represent a significant undertaking, companies who invest in them should see considerable benefit in terms of launch preparedness, relationship building and market penetration.
