Lysosomal storage disorders are a group of
rare inherited metabolic diseases.

Lysosomal storage disorders (LSDs) are characterized by the abnormal accumulation of toxic materials such as cellular fats or sugars as a result of enzyme deficiencies. This build-up can affect various parts of the body, including the brain, central nervous system (CNS) and skeletal system. Our unique approaches to treat LSDs include upregulating the cellular clearance of these wastes, attenuation of inflammation throughout the body, and promotion of neuronal survival.

 

Polaryx’s pipeline is comprised of uniquely formulated New Chemical Entities (NCE), repurposed drugs, and gene therapy candidates to treat these diseases. We are currently preparing to launch a clinical trial to validate the safety and efficacy of our leading drug candidate.

Why Polaryx?

There is an urgent need for novel therapeutic interventions for lysosomal storage disorders, including neuronal ceroid lipofuscinosis, Krabbe Disease, Sandhoff Disease, and Niemann-Pick Type A / B Diseases.

 

Polaryx Therapeutics was founded in 2014 with the singular aim of addressing these unmet needs with a strong scientific basis and patient-friendly routes of administration.
