This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- AEX-2
- Announced Date:
- February 27, 2025
- Indication:
- Non-Sulfonamide Dual Orexin Receptor
Announcement
NLS Pharmaceutics Ltd. announce new preclinical findings on AEX-2, reinforcing its potential as a first-in-class non-sulfonamide dual orexin receptor agonist ("DOXA") for narcolepsy and related neurological disorders.
AI Summary
NLS Pharmaceutics Ltd. recently announced promising preclinical findings on AEX-2, a novel non-sulfonamide dual orexin receptor agonist (DOXA) aimed at treating narcolepsy and related neurological disorders. In studies using orexin-deficient mouse models, AEX-2 demonstrated a significant boost in wakefulness, maintaining stable wake architecture without causing disruptive sleep patterns. The compound also effectively preserved REM sleep and reduced the frequency and duration of cataplexy episodes, a key symptom in narcolepsy type 1. These early results suggest that AEX-2 could be a safer and more targeted alternative to current orexin-based therapies. With its potential to address both sleep disturbances and underlying neurodegenerative issues, this preclinical data reinforces AEX-2 as a first-in-class agent, paving the way for further development and eventual clinical trials for a broader range of neurological conditions.

alpha-synuclein - FDA Regulatory Timeline and Events
alpha-synuclein is a drug developed by NLS Pharmaceutics for the following indication: For Parkinson's Disease Treatments.
This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- alpha-synuclein
- Announced Date:
- June 27, 2024
- Indication:
- For Parkinson's Disease Treatments
Announcement
NLS Pharmaceutics Ltd announced preclinical results from multiple in vitro studies targeting alpha-synuclein (α-synuclein), specifically the A53T mutation, that demonstrate the compounds' potential to advance the treatment of Parkinson's Disease (PD). The compounds may be used by NLS pursuant to its existing and previously announced license agreement with Aexon Labs, Inc. (Aexon Labs or AEX).
AI Summary
NLS Pharmaceutics Ltd. announced promising preclinical results from several in vitro studies focused on the A53T mutation of alpha-synuclein, a protein linked to Parkinson’s Disease. The studies showed that certain compounds can boost neurite outgrowth, which is important for neuron health and regeneration. This positive effect suggests these compounds might help reduce the toxic buildup of alpha-synuclein in brain cells.
The compounds investigated were developed using NLS’s next-generation non-sulfonamide dual orexin agonist (DOXA) platform and are available under NLS’s existing license agreement with Aexon Labs, Inc. These early findings indicate that the Aexon Labs compounds may pave the way for innovative treatments by enhancing neuronal connectivity and resilience, offering potential new avenues to advance the treatment of Parkinson’s Disease. Further research including in vivo studies is planned to determine their safety and long-term benefits.

iTOL-102 - FDA Regulatory Timeline and Events
iTOL-102 is a drug developed by NLS Pharmaceutics for the following indication: Type 1 Diabetes Treatment.
This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- iTOL-102
- Announced Date:
- February 25, 2025
- Indication:
- Type 1 Diabetes Treatment
Announcement
NLS Pharmaceutics Ltd. announced y the result from the Type B pre-IND meeting held by Kadimastem and iTolerance with a committee of the U.S Food and Drug Administration ("FDA") on February 24, 2025, regarding the development of iTOL-102, a potential cure for diabetes that would not require life-long chronic immune system suppression.
AI Summary
NLS Pharmaceutics Ltd. announced a significant milestone following a Type B pre-IND meeting held on February 24, 2025, with a committee from the U.S. FDA. This meeting, conducted jointly by Kadimastem and iTolerance, focused on the development of iTOL-102—a promising investigational therapy for Type 1 diabetes. iTOL-102 combines Kadimastem’s allogenic human stem cell-derived pancreatic islets with iTolerance’s immunomodulator, iTOL-100, to potentially cure diabetes without requiring lifelong immunosuppression. The FDA provided critical feedback on current preclinical and clinical development plans, paving the way for updated safety toxicology studies and the preparation for a First-in-Human clinical trial. This feedback marks an important advancement in the clinical development of iTOL-102, highlighting its potential to transform diabetes treatment by offering a solution that avoids chronic immune suppression.

Mazindol - FDA Regulatory Timeline and Events
Mazindol is a drug developed by NLS Pharmaceutics for the following indication: For the treatment of narcolepsy, and potentially other sleep-wake disorders.
This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- Mazindol
- Announced Date:
- May 21, 2025
- Indication:
- For the treatment of narcolepsy, and potentially other sleep-wake disorders
Announcement
NLS Pharmaceutics Ltd announces that it will present new preclinical data on Mazindol ER at the 2025 Annual Meeting of the American Society of Clinical Psychopharmacology ("ASCP").
AI Summary
NLS Pharmaceutics Ltd., a Swiss clinical-stage biopharmaceutical company focused on central nervous system disorders, announced that it will present new preclinical data on Mazindol ER at the 2025 Annual Meeting of the American Society of Clinical Psychopharmacology (ASCP). The meeting is scheduled for May 27-30, 2025, in Scottsdale, Arizona, and NLS will showcase its poster titled “Evaluating the Effects of Mazindol on Fentanyl Reward and Dependence in C57BL/6J Mice and Sprague-Dawley Rats (Study KO-943)” on May 29, during the poster session.
The preclinical study, performed with Key-Obs SAS and European academic partners, shows that Mazindol significantly reduces the rewarding effects of fentanyl and lessens its withdrawal symptoms in rodent models. These findings support further exploration of Mazindol ER as a potential non-opioid treatment for opioid dependence.
Read Announcement- Drug:
- Mazindol
- Announced Date:
- January 28, 2025
- Indication:
- For the treatment of narcolepsy, and potentially other sleep-wake disorders
Announcement
NLS Pharmaceutics Ltd announce the launch of a preclinical program evaluating Mazindol ER (Extended-Release) as a novel treatment for fentanyl dependence.
AI Summary
NLS Pharmaceutics Ltd, a Swiss clinical-stage biopharmaceutical company, has launched a preclinical program to test Mazindol ER (Extended-Release) as a new treatment for fentanyl dependence. This program will study whether Mazindol ER can safely and effectively reduce the symptoms of fentanyl addiction, including withdrawal and cravings, by targeting different neurotransmitter systems in the brain. The treatment may help rebalance neurochemical disruptions that occur with opioid addiction. Researchers will assess the drug’s safety, its long-lasting effects, and how it impacts both opioid withdrawal symptoms and cravings in laboratory models. The extended-release format of the drug is designed to provide a steady therapeutic effect, which could be an important advantage in managing dependence. If the preclinical study shows positive results, NLS may move forward with clinical trials to further explore this novel non-opioid treatment approach.
