Description

Summary

The goal of this clinical trial is to test ATX-01 in participants with myotonic dystrophy type 1 (DM1). The main question it aims to answer is if ATX-01 is safe and well tolerated. The trial will compare the safety and tolerability of ATX-01 and a matching placebo.

There will be a single-ascending dose part of the trial and a multiple-ascending dose part. In the single-ascending dose, participants will receive one dose of ATX-01 or placebo. In the multiple-ascending dose part, participants will receive three doses of ATX-01 or placebo.

ATX-01 is a novel anti-miR (synthetic single stranded oligonucleotide) that inhibits a microRNA called miR-23b.

Official Title

A Phase 1/2a Double-Blind, Placebo-controlled, Single- and Multiple Ascending Dose Study to Assess the Safety, Tolerability, PK, PD and Efficacy of IV Administration of ATX-01 In Male and Female Participants Aged 18 to 64 With Classic DM1

Keywords

Myotonic Dystrophy 1, Myotonic Dystrophy, ATX-01
