ZURICH, SWITZERLAND / ACCESSWIRE / December 14, 2022 / NLS Pharmaceutics Ltd. (NASDAQ:NLSP,)(NASDAQ: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 the closing of its previously publicized purchase agreement with BVF Partners L.P. ("BVF") comprised of an initial closing of $10 million in exchange for 11,494,253 common shares (or equivalents), representing a purchase price per share of $0.87.

As part of the financing, in a second potential closing, BVF will have the right, following a successful end of phase 2 meeting with the U.S. Food and Drug Administration ("FDA"), among other closing conditions, to purchase units at a per unit purchase price of $1.50, which units will consist of common shares (or equivalents), as well as a common share warrant to purchase up to one and a half common shares at an exercise price of $2.03 per share. If this option is exercised in full, BVF will receive 20 million common shares plus common share warrants to purchase 20 million NLS common shares at $2.03 per share.

NLS intends to use the net proceeds from the offering to accelerate the ongoing clinical development of its lead product, Mazindol ER for the treatment of narcolepsy, to advance NLS-4 and other product candidates, to support business development and licensing activities, and for general corporate purposes. With this financing, NLS expects to be able to fund its operations through 2025, beyond the anticipated submission of its New Drug Application for Mazindol ER in narcolepsy, expected in late 2024 or early 2025.

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 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 trial evaluating Quilience^® in adult subjects 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 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.
