Brief summary
This study is an open label Phase II study to evaluate the safety and efficacy of AMX0035 in adults with Wolfram syndrome.
Detailed description
AMX0035 is a combination therapy designed to reduce neuronal death through blockade of key cellular death pathways originating in the mitochondria and endoplasmic reticulum (ER). This clinical trial is designed to demonstrate that treatment is safe, tolerable, and to evaluate the effect of AMX0035 on residual beta cell functions by monitoring c-peptide levels during a 0-240 minute mixed-meal tolerance test. The trial will also assess the effects of AMX0035 on changes to diabetic measurements including daily insulin dose, time in good glucose range, and HbA1c levels. Effect on best-corrected visual acuity in both eyes will also be evaluated.

Eligibility
Inclusion criteria
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
