Eligibility Criteria
Inclusion Criteria
- DNA proven CMT1A
- Muscle weakness in at least foot dorsiflexion (clinical assessment)
- Age between 18 and 65 years
- Male or non pregnant, non breastfeeding female
- CMT neuropathy score at screening ≤ 20
- Agrees to perform electrorophysiological studies and two cutaneous biopsies for determination of PMP22 expression and histology
- Providing signed written informed consent to participate in the study and willing and able to comply with all study procedures and scheduled visits
Exclusion Criteria
- Patients with another neurological disease
- Patients using unauthorized concomitant treatments, ascorbic acid, opioids, levothyroxine and potentially neurotoxic drugs. Patients who can/agree to stop these medications 4 weeks before randomization can be included
- Patients who have participated in another trial of investigational drug within the past 30 days
- Concomitant major systemic disease
- Clinically significant history of unstable medical illness over the last 30 days (unstable angina…)
- History of significant hematologic, kidney, liver disease, or insulin-dependent diabetes
- Clinically significant abnormalities on the prestudy laboratory evaluation, physical evaluation, electrocardiogram (ECG)
- ASAT/ALAT levels above the upper limit of normal (ULN). However, patients with an isolated elevation of either ASAT or ALAT (<1.5 ULN) can be included at investigators" discretion if the remaining liver function tests are normal and if ASAT or ALAT value is stable at 2 distinct evaluations in the month prior to inclusion
- Serum creatinine levels above the upper limit of normal
- Limited mental capacity or psychiatric disease rendering the subject unable to provide written informed consent or comply with evaluation procedures
- History of recent alcohol or drug abuse or non-adherence with treatment or other experimental protocols
- Female of childbearing potential (apart of patient using adequate contraceptive measures), pregnant or breast feeding
- Suspected inability to complete the study follow-up (foreign workers, transient visitors, tourists or any others for whom follow-up evaluation is not assured)
- Limb surgery in the six months before randomization or planned before completion of the trial
- Known hypersensitivity to any of the individual components of PXT3003
- Porphyria
