Summary

The study will consist of 2 periods: Double-blind Treatment and Open-Label Extension(OLE) Period.

-Double-blind Treatment Period - This will be randomized, double-blind, placebo-controlled part of the study which will be conducted in parallel groups, ie,1 group receiving the active treatment (PXT3003) and the other group receiving placebo.

Primary endpoint of the study will be assessed at Month 15.

-Open-label Extension (OLE) Period - All subjects completing Double-blind Treatment Period will be given an opportunity to enter the OLE Period of the study and receive the active treatment (PXT3003). The duration of the OLE Period will be based on Sponsor discretion, ie, Sponsor intends to keep the study open until the study drug PXT3003 is commercially available.

During this period, the long-term safety and efficacy of PXT3003 will be assessed as an exploratory objective.

Double-blind Treatment Period Objectives:

Primary:

To evaluate the efficacy of treatment with PXT3003 (a fixed-dose combination of \[RS\]-baclofen, naltrexone hydrochloride \[HCl\], and D-sorbitol) compared to placebo in subjects with Charcot-Marie-Tooth disease type 1A (CMT1A).

Secondary:

To evaluate the safety and tolerability of PXT3003 treatment in subjects with CMT1A.

Exploratory:

To characterize the relationship between plasma biomarkers and response to PXT3003 treatment.

OLE Period Objective:

Exploratory:

To evaluate the long-term safety and efficacy of PXT3003.
