Dear Friends,

 

Thank you sincerely for your invaluable support of our collaborative study alongside Prilenia Therapeutics. 

One promising candidate is the Sigma 1 receptor, and we have initiated a collaboration with Prilenia, a biotech company specializing in this field. Together, we are investigating the effects of a drug called pridopidine, which targets the Sigma 1 receptor, in cellular models of Wolfram syndrome. We are grateful to the Snow Foundation in collaboration with Ellie White Foundation for their generous donations, which enables us to conduct this crucial study using cells derived from Wolfram syndrome patients. The study is currently in progress as we explore various experimental conditions to assess the efficacy of pridopidine. We are committed to providing you with regular updates on our progress.

 

Once again, we extend our heartfelt thanks for your generous support, which is instrumental in advancing our mission to find a cure for Wolfram syndrome and bring hope to those affected by this condition.

 

With grace and gratitude,

Fumi

AMYLYX PHARMACEUTICALS Helios Update

AMYLYX PHARMACEUTICALS
Helios Update

Earlier in February 2024, Amylyx Pharmaceuticals announced that enrollment was completed in the Phase 2 HELIOS clinical trial of AMX0035 (sodium phenylbutyrate and taurursodiol) for the treatment of Wolfram syndrome.

HELIOS is a 48-week exploratory, open-label proof of biology study assessing the effect of AMX0035 on a number of measures, including pancreatic function (mainly pertaining to diabetes), visual function, and Wolfram syndrome disease rating instruments.

The study, being conducted at Washington University in St. Louis, has enrolled 12 adult participants living with Wolfram syndrome, and preliminary results are anticipated in the second half of 2024. Data from this initial study will play an important role in giving Amylyx information needed to make decisions for potential future trials. Amylyx looks forward to sharing the results with the community, including at scientific meetings, when they are available.
