ZURICH, SWITZERLAND / ACCESSWIRE / December 11, 2024 / 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 that its Chief Executive Officer, Alex Zwyer, has issued the following letter to shareholders:

Dear Valued Shareholders,

As we move forward with exciting developments at NLS, I want to update you on the significant progress we've made, key challenges we've overcome, and the strategic opportunities that lie ahead-especially as we approach the expected closing of our transformative merger with Kadimastem Ltd. ("Kadimastem"), an advanced clinical-stage company.

The DOXA Program

Over the past several months, we've made substantial progress with our Dual Orexin Receptor Agonist (DOXA) platform, which we believe holds considerable promise in addressing key challenges in the treatment of sleep and neurodegenerative diseases. Recently, we announced details around our preclinical program to evaluate two candidates, AEX-41 and AEX-2, two first-in-class non-sulfonamide DOXAs designed to target both orexin-1 (OX1R) and orexin-2 (OX2R) receptors while concurrently inhibiting cathepsins. This unique approach aims to address the unmet therapeutic needs in narcolepsy and related neurological disorders.

The preclinical study is being conducted at the Centre for Neurological Research of Lyon (France), a world-class institution specializing in sleep and neurological research, and aims to evaluate the potential superiority of AEX compounds over existing therapies in the space by using an internationally validated orexin knockout (ORX-KO) mouse model of narcolepsy.While existing selective OX2R agonists have demonstrated efficacy in managing narcolepsy symptoms, DOXA are expected to surpass these benchmarks. By engaging both OX1R and OX2R receptors and addressing broader neurological pathways, AEX-41 and AEX-2 offer the potential for enhanced therapeutic outcomes, including greater wakefulness stability and improved sleep quality under real-world conditions.

Earlier in December, we shared preliminary results from this ongoing study of AEX-41 in narcolepsy models which suggested that the compound shows promise as a therapeutic agent for managing narcolepsy-related sleep-wake disturbances.

Key findings from the study included:

• Wakefulness: Increased stability with fewer interruptions.

• Slow-Wave Sleep (SWS): Reduced fragmentation and improved continuity.

• REM Sleep: Significant reduction in pathological episodes.

Final top line results from the ongoing study are expected to be shared by the end of this year. In addition, the Company's broader development plans include exploring the application of its DOXA platform also in other neurodegenerative conditions, such as Amyotrophic Lateral Sclerosis (ALS).

Overcoming Obstacles

Despite significant challenges over the past few months, we have successfully positioned NLS for the next phase of growth:

- Financial growth and Nasdaq Compliance: After a period of risk regarding our Nasdaq listing, we are pleased to have regained full compliance with all Nasdaq continued listing requirements. This achievement was a result of our successful efforts to improve our balance sheet, including settlement agreements with vendors and successfully fundraising from private as well as institutional investors. Full compliance allows us, and eventually the combined company, continued access and exposure to the U.S. capital markets.

- Financial Restructuring: In addition, we have made important strides in eliminating all debt and strengthening our balance sheet. In October 2024, we closed a $3.2 million private placement and in December we announced a second private placement raising up to $1 million at a price of $3.10, representing a 15% premium to the market, subject to certain closing conditions including shareholder approval. The two private placements together (if closed), with our existing cash position, extends our runway to approximately 18 months. This new influx of capital also gives us flexibility to execute our strategy including the development of the DOXA compounds and complete the merger process smoothly.

Merger with Kadimastem Ltd.

In addition to solving our listing and financial challenges, we also announced a potential merger with Kadimastem, a company we believe offers compelling strategic benefits, not only for the combined company but also for our shareholders. Kadimastem's expertise in the development of innovative cell-based therapies will allow the DOXA program to thrive, and once the merger is finalized, these programs will become part of the merged company's broader pipeline of neurodegenerative and diabetes candidates.

While Kadimastem will assume ownership of the active pipeline assets, including the DOXA program, NLS shareholders will retain an exclusive opportunity to benefit financially from the potential sale of our legacy assets, including Mazindol, through the contingent value rights (CVR) agreement associated with the merger.

Mazindol, which has long been part of our portfolio, is a key asset that received significant attention from private companies and therefore we believe holds significant potential for future value generation post-merger. We remain committed to maximizing this opportunity.

Looking Ahead: A Focused Strategy on Value Creation

The recent months have been a time of great challenge and achievement for NLS. As the merger is expected to close by the end of January 2025 and the integration process begins, we remain grateful for your continued support. We are committed to maximizing shareholder value through the potential sale of our legacy assets in the CVR and the combined company's strengthened neurodegenerative and diabetes focused advanced clinical pipeline. With this strategy in place, we look forward to a future that is focused on value creation and the success of the DOXA program under Kadimastem's leadership.

Thank you for your ongoing support as we move forward with this exciting next chapter.

Sincerely,

Alex Zwyer, CEO
