**ZURICH, SWITZERLAND – JULY 17, 2025** – NLS Pharmaceutics Ltd. (Nasdaq: NLSP) ("NLS"), a Swiss clinical-stage biopharmaceutical company focused on central nervous system disorders, today announced that the Israel-U.S. Binational Industrial Research and Development Foundation (the "Bird Foundation") has approved another milestone-based funding payment to Kadimastem Ltd. (TASE: KDST) ("Kadimastem"), a clinical-stage cell therapy company developing "off-the-shelf," allogeneic regenerative treatments for neurodegenerative diseases and diabetes, with a U.S.-based company, iTolerance, Inc. ("iTolerance"). The milestone payment is based on the significant progress demonstrated by the companies in the co-development of iTOL-102, a novel cell therapy targeting a potential cure for Type 1 diabetes without the need for life-long immunosuppression.

This news follows the February 2025 announcement by NLS and Kadimastem regarding the successful completion of a Type B Pre-IND meeting with the U.S. Food and Drug Administration (the "FDA"). The FDA provided constructive guidance on the clinical development pathway, enabling the companies to advance toward initiating First-in-Human clinical trials of iTOL-102. The BIRD Foundation's approval of a fifth disbursement of funds is based on the program's recent scientific and regulatory progress.

The milestone payment approved by the BIRD Foundation amounts to approximately NIS 564,400 ($166,000 USD), bringing the total support from the BIRD Foundation to nearly NIS 3 million ($882,352 USD) to date. NLS and Kadimastem believe that the continued financial backing reflects the BIRD Foundation's ongoing confidence in the collaboration between Kadimastem and iTolerance and the clinical promise of iTOL-102.

**Ronen Twito, Executive Chairman and CEO of Kadimastem**, commented:

"We believe that the BIRD Foundation's decision to release this additional tranche of funding is a strong endorsement of the remarkable scientific and regulatory progress we've achieved with iTolerance. Our successful Pre-IND meeting with the FDA marks a pivotal step on the path to clinical development, and we are energized by the potential of iTOL-102 to redefine what is possible for patients with Type 1 diabetes."

**Anthony Japor, CEO of iTolerance added**, "We believe that the continued support from the BIRD Foundation, especially following our productive Pre-IND meeting with the FDA, is a strong validation of the significant progress we've made in developing iTOL-102. This milestone brings us another step closer to offering a functional cure for patients living with Type 1 diabetes—without the burden of lifelong immunosuppression. We are proud of our collaboration with Kadimastem and look forward to advancing this transformative therapy into clinical trials."

**Alex Zwyer, Chief Executive Officer of NLS Pharmaceutics**, stated:

"We are encouraged by the continued external validation and momentum in the iTOL-102 program, particularly as the merged company prepares to initiate key clinical studies in diabetes. This milestone further reinforces the strong scientific and strategic rationale behind our proposed merger with Kadimastem."

Kadimastem's IsletRx technology, a scalable, stem cell-derived source of insulin-producing islet-like cells, is combined with iTolerance' s proprietary iTOL-100 immunomodulatory platform in iTOL-102. In preclinical studies, the combined therapy demonstrated functional insulin secretion and disease reversal in diabetic animal models. The product has been tested at the Diabetes Research Institute at the University of Miami and is regarded as a potential breakthrough in transplant-based diabetes therapies.

The companies are currently preparing for safety toxicology studies and the initiation of clinical trial submissions based on FDA guidance.

NLS is also proud to announce that Dr. Eric Konofal, Chief Scientific Officer at NLS, has been recommended for the prestigious Prix Galien in the pharmaceutical biotech industry. Dr. Konofal's exceptional contributions to pediatric sleep medicine and sleep disorders, particularly narcolepsy type 1 (NT1), have gained international recognition. His groundbreaking research at the Pediatric Center for Sleep Disorders, Functional Explorations Department, DMU INNOV, INSERM U1141 – NeoPhen Team, Robert Debré University Hospital, AP-HP. Nord – Université de Paris, includes the development of dual OX1R/OX2R agonists, AEX-2 and AEX-41, aimed at comprehensive symptom management such as cataplexy and wakefulness. This work, presented at ASCP 2025, draws from his early research on wakefulness and inflammation reduction through Cathepsin H inhibition, and pushes forward innovative solutions for NT1, including potential cell therapy approaches.
