What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests if ADX-629, a medicine taken by mouth, is safe and effective for people with Sjögren-Larsson syndrome (SLS). SLS is a rare genetic disorder that causes harmful fats to build up in the body. ADX-629 helps remove these harmful fats, which may reduce symptoms in the skin, brain, and eyes.

Will I have to stop taking my current medications?

The trial requires participants to stop using all topical creams 7 days before the study and any experimental drugs 1 month before the study. If you are on immunosuppressive therapy or certain systemic or topical medications, you must be willing to stop them 2 weeks before and during the study.

What makes the drug ADX-629 unique for treating Sjögren-Larsson syndrome?

The research does not provide specific information about how ADX-629 works for Sjögren-Larsson syndrome, so its unique aspects compared to other treatments are not clear from the available data.12345

Are You a Good Fit for This Trial?

Adults aged 18-50 with Sjogren-Larsson Syndrome (SLS), weighing at least 35 kg, able to swallow pills and follow the study plan. Participants must have ichthyosis, spasticity, a genetic confirmation of SLS, and agree to contraception if sexually active. Excluded are those in other studies, with certain health conditions or treatments that could affect results or safety.

What Are the Treatments Tested in This Trial?

Interventions

  • ADX-629
Trial Overview The trial is testing ADX-629's safety and effectiveness for treating SLS when taken orally for 12 weeks. It aims to reduce harmful fatty aldehydes believed to cause symptoms by trapping these molecules. The drug's impact on skin, neurological function, and eye health will also be explored.

Published Research Related to This Trial

Sjögren-Larsson syndrome (SLS) is a rare inherited disorder caused by mutations in the ALDH3A2 gene, leading to symptoms like ichthyosis, mental retardation, and spastic diplegia, as seen in two diagnosed brothers aged 12 and 20.
The study identified a novel homozygous mutation (c. 835 T > A) in the ALDH3A2 gene in these patients, contributing to the understanding of the genetic basis of SLS and its associated demyelinating disease.

The Sjögren-Larsson syndrome (SLS) gene has been successfully linked to a specific region on chromosome 17, based on a study involving families from the United States, Egypt, and Israel, which supports the idea of a single genetic cause for this rare disorder.
The identification of this gene location can aid in the diagnosis and carrier detection of SLS across diverse populations, as evidenced by the homozygosity observed in consanguineous families, indicating a shared genetic background.

Sjögren-Larsson syndrome (SLS) is a rare genetic disorder that leads to intellectual disability, spastic diplegia or tetraplegia, and congenital ichthyosis, along with specific eye features like macular glistening dots.
This study presents two cases of SLS and highlights previously unreported changes in fundus autofluorescence, which could provide new insights into the ocular manifestations of the syndrome.
