25 March 2025 - Transgenic mouse study adds support for development of NLX-101 for treatment of Rett Syndrome

New data from researchers at the University of Minho, Portugal, and from the University of Bristol, UK, show that NLX-101, a selective serotonin 5-HT1A receptor ‘biased agonist’ that targets specific brain regions, could bring much-needed hope to Rett syndrome patients and their carers.

The study, supported by the International Rett Syndrome Foundation (https://www.rettsyndrome.org/) and published in the peer-reviewed journal Biomedicine and Pharmacotherapy, examined the effects of NLX-101 in mice that lack genetic expression of MeCP2 (methyl CpG binding protein 2), thus mimicking human Rett syndrome. The results suggest that NLX-101 can attenuate the damaging respiratory impairment and cognitive deficits seen in individuals with Rett syndrome. 

Rett syndrome is characterized by severe neurophysiological, respiratory and cognitive impairment, and affects approximately 15 000 patients in the US. NLX-101 has ‘Orphan Drug’ designation and has begun Phase 1 human study. The present data support its further development for treatment of Rett syndrome and related clinical indications."

18 March 2025 - Neurolixis Publishes Positive Phase 2A Trial Results for NLX-112 in Parkinson’s Disease

Neurolixis today announced the publication of the results from its successful Phase 2A proof-of-concept clinical trial of NLX-112 (befiradol) in Parkinson’s disease. The findings, published in the prestigious journal 𝘔𝘰𝘷𝘦𝘮𝘦𝘯𝘵 𝘋𝘪𝘴𝘰𝘳𝘥𝘦𝘳𝘴, highlight NLX-112’s potential as a first-in-class, non-dopaminergic therapy with dual efficacy in addressing both levodopa-induced dyskinesia (LID) and motor impairment in Parkinson’s patients. The randomized, double-blind, placebo-controlled trial, supported by The Michael J. Fox Foundation and Parkinson’s UK, evaluated NLX-112 in patients with troubling LID. The study successfully met its primary endpoint of safety and tolerability, as well as its secondary endpoint of significantly reducing LID. Notably, NLX-112 also demonstrated anti-parkinsonian effects, significantly improving motor function in study participants.

𝗔 𝗡𝗼𝘃𝗲𝗹 𝗠𝗲𝗰𝗵𝗮𝗻𝗶𝘀𝗺 𝗼𝗳 𝗔𝗰𝘁𝗶𝗼𝗻: Unlike current Parkinson’s treatments that target the dopamine system, NLX-112 acts on the serotonin (5-HT) system, as a highly selective full activator of 5-HT1A receptors. This unique mechanism differentiates NLX-112 from previous serotonergic drugs and is believed to underlie its dual efficacy in reducing dyskinesia and improving motor function. The promising results from this Phase 2A trial support further development of NLX-112 as a transformative therapy for movement disorders. Neurolixis is actively planning next steps in the clinical development program to advance NLX-112 toward potential regulatory approval.

𝗔𝗯𝗼𝘂𝘁 𝗣𝗮𝗿𝗸𝗶𝗻𝘀𝗼𝗻’𝘀 𝗗𝗶𝘀𝗲𝗮𝘀𝗲 𝗮𝗻𝗱 𝗥𝗲𝗹𝗮𝘁𝗲𝗱 𝗠𝗼𝘃𝗲𝗺𝗲𝗻𝘁 𝗗𝗶𝘀𝗼𝗿𝗱𝗲𝗿𝘀: Parkinson’s disease is the second most common neurodegenerative disorder, affecting over 10 million people worldwide. Levodopa, the mainstay treatment for Parkinson’s, often leads to debilitating dyskinesias (involuntary movements) after prolonged use. Up to 80% of patients develop LID within ten years of levodopa therapy. Current treatments for LID, such as amantadine, are limited by side effects and variable efficacy, underscoring the need for new therapeutic options.
As well as Parkinson’s disease, other disorders also involve dysfunction in the basal ganglia, a brain region critical for coordinating movement. Such disorders include spinocerebellar ataxia, Huntington’s disease, essential tremor and dystonia, and lead symptoms such as tremors, rigidity, and impaired motor control.

24 January 2025 - Neurolixis advancing drug candidates for rare neurological disorders

Neurolixis is making strides in developing first-in-class treatments for rare neurological disorders. The lead drug candidate, NLX-112, is Phase 2-ready and has received Orphan Drug designation for treating Spinocerebellar Ataxia. With a proven safety record in over 600 subjects and beneficial motor effects in people with Parkinson’s disease, NLX-112 could be a breakthrough in the movement disorders field.
Additionally, NLX-101 (Phase 1) has Orphan Drug designation for treating Autism Spectrum Disorders: Fragile X syndrome and Rett syndrome, two debilitating neurodevelopmental conditions with high medical need.
Both NLX-112 and NLX-101 have neuroprotective and neuroplastogenic effects, suggesting disease modifying therapeutic activity.
Neurolixis CEO, Adrian Newman-Tancredi, recently presented our rare disease pipeline at the Executive Roundtable organized by WuXi Apptec..

25 September 2024 - Neurolixis granted Orphan Medicinal Product Designation for NLX-112 as a Treatment for Spinocerebellar Ataxia

NLX-112, a highly selective serotonin 5-HT1A receptor agonist, has been granted Orphan Medicinal Product (OMP) Designation by the European Commission for the treatment of Spinocerebellar Ataxia (SCA; approval #EU/3/24/2951). This decision follows a positive recommendation from the Committee for Orphan Medicinal Products (COMP). SCA is a group of rare genetic disorders, most notably Machado-Joseph Disease (SCA3), which leads to progressively worsening neurological symptoms such as clumsiness, muscle weakness, and tremors, often resulting in severe disability. The OMP designation for NLX-112 was awarded following a successful collaboration between Neurolixis and Professor Patricia Maciel's team at the University of Minho in Portugal. This partnership, funded by the U.S. Department of Defense, showed that NLX-112 significantly reduces motor dysfunction in a transgenic mouse model of SCA3.

04 June 2024 - Neurolixis issued a new US patent for treatment of Fragile X syndrome with NLX-101

United States Patent and Trademark Office (USPTO) granted a patent (US11974992B2) covering the use of NLX-101, a clinical phase drug candidate, for treatment of Fragile X syndrome (FXS). FXS is a rare genetic autism spectrum disorder which affects about 1 in 5000 individuals and is a leading cause of inherited intellectual disability. There are no approved treatments for Fragile X syndrome. Neurolixis has already shown that NLX-101 has robust activity in transgenic models of another autism spectrum disorder (Rett syndrome) and the new patent expands the company's presence in the orphan autism disorder indication space.  

Fragile X syndrome is a genetic disorder caused by a mutation in the FMR1 gene. It is the most common form of inherited intellectual disability and the leading cause of autism-like symptoms in males. Symptoms include intellectual disability, physical features, and behavioral symptoms. Genetic testing and physical examination are used for diagnosis. Supportive care and medications can help manage symptoms but there is no cure or approved treatment. The incidence of Fragile X syndrome is approximately 1 in 4,000 males and 1 in 8,000 females; in the United States 60 to 80 thousand individuals are affected.

25 August 2023 - Dual Clinical Efficacy of NLX-112 in Parkinson's Disease to be Presented at Movement Disorders Society Congress

NLX-112, a ground-breaking, non-dopaminergic drug, exhibited both anti-dyskinetic and anti-parkinsonian properties in a proof-of-concept Phase 2A clinical trial. The positive findings were presented in July as a ‘Hot Topics’ oral presentation at the World Parkinson’s Congress in Barcelona, Spain (see video). They will also be presented at the forthcoming Movement Disorders Society Congress in Copenhagen, Denmark, on Wednesday, August 30 (Poster #1435). The dual clinical efficacy profile of NLX-112 arises from its innovative mechanism of action. Unlike most current anti-parkinsonian medications, NLX-112 does not target the dopaminergic system, and is a highly selective, serotonin 5-HT1A receptor activator.
