This study is an open label Phase II study to evaluate the safety and efficacy of AMX0035 in adults with Wolfram syndrome.
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.
