ORYZON to Present Positive Preclinical Efficacy Data of ORY-4001 in Charcot-Marie-Tooth (CMT) Disease at the 2023 Peripheral Nerve Society (PNS) Annual Meeting

  • Selected for Oral Presentation
  • Study done in the CMT1A mouse model
  • Supported by the CMT Research Foundation

MADRID, Spain and BOSTON, May 30, 2023 (GLOBE NEWSWIRE) — Oryzon Genomics, S.A. (ISIN Code: ES0167733015, ORY), a clinical-stage biopharmaceutical company leveraging epigenetics to develop therapies in diseases with a strong unmet medical need, announced today that it will present positive preclinical efficacy data of ORY-4001 in a CMT model at the 2023 Peripheral Nerve Society (PNS) Annual Meeting, which will be held June 17-20 at the Bella Center in Copenhagen, Denmark. The scientific committee of the 2023 PNS Annual Meeting has selected “ORY-4001, a Novel Potent and Selective Oxadiazole-Based HDAC6 Inhibitor Shows Pre-Clinical Therapeutic Efficacy in CMT1A” for an oral presentation, which will take place on Tuesday, June 20, at 08:40 am CEST.

In 2022, Oryzon and the CMT Research Foundation (CMTRF), a U.S.-based patient-led, non-profit organization focused on delivering treatments and cures for CMT, entered into an agreement to explore the therapeutic potential of Oryzon’s histone deacetylase 6 (HDAC-6) inhibitors. Following positive preclinical results obtained under this collaboration, Oryzon selected a candidate for clinical development, ORY-4001. This compound is a HDAC6 inhibitor with excellent pharmacology and very high selectivity against other HDAC classes, resulting in a remarkable safety profile avoiding hematotoxicity. The compound exhibits strong anti-inflammatory properties and positive in-vivo data in inflammatory models. In the study to be presented at the 2023 PNS Annual Meeting, ORY-4001 showed multiple positive responses in a validated CMT1A peripheral neuropathy in vivo model which effectively mimics many of the symptoms of this condition in humans.

Dr. Jordi Xaus, Oryzon’s CSO, said: “Although this is only a first proof-of-concept preclinical model of a peripheral neuropathy, the robustness of the data obtained in this CMT1A model is really encouraging and prompts us to intensify our efforts to pursue IND enabling studies to support first-in- human administration of ORY-4001 in the following quarters.”

CMT is a progressive, degenerative disease that causes damage to the peripheral nerves. It affects 150,000 Americans and more than 3 million people around the world. It is one of the most prevalent conditions among rare diseases and currently lacks effective treatments or cures. CMT is caused by a variety of genetic mutations. CMT1A is the most prevalent form, accounting for approximately half of all people with CMT.

About ORY-4001
ORY-4001 is a highly selective histone deacetylase 6 (HDAC-6) inhibitor. Due to its positive pharmacological properties, it was recently nominated as a clinical development candidate for the treatment of certain neurological diseases such as Charcot-Marie-Tooth disease (CMT), Amyotrophic Lateral Sclerosis (ALS), and others. HDAC6 inhibitors have been previously proposed as potentially effective treatments for CMT, ALS, and other neurological disorders that lack effective treatments.
