Hope for rare wolfram syndrome: drug aims to slow diabetes progression
NCT ID NCT05676034
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests an experimental drug called AMX0035 in 12 adults with Wolfram syndrome, a rare genetic disorder that causes diabetes and vision loss. The goal is to see if the drug can help preserve the pancreas's ability to make insulin and to check its safety over up to 4 years. Participants take the drug by mouth and wear a continuous glucose monitor throughout the study.

Key Inclusion Criteria: * Definitive diagnosis of Wolfram syndrome * Insulin dependent diabetes mellitus due to Wolfram syndrome * At least 17 years of age * Participant must be willing to wear a CGM device for the duration of the study Key Exclusion Criteria: * Presence of pathologies that can alter the enterohepatic circulation of bile acids (e.g., ileal resection and stoma, regional ileitis) * Any history of heart failure per New York Heart Association (NYHA) * History of or family history of breast and/or ovarian cancer * Participant under severe salt restriction where the added salt intake due to treatment would put the patient at risk, in the Investigator's judgment * Received treatment with any investigational drug or device within the 30 days (or 5 half-lives, whichever is longer) prior to first dose at Day 1 * Previous treatment with gene or cellular therapy
