Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Children who are enrolled in this trial, will have CMT1A. They will have a course of 6 monthly botulinum toxin injections for 2 years into one leg. This leg will be chosen at random, and the other leg will act as the control.
Intervention code [1] 130 0
Treatment: Drugs
Comparator / control treatment
The other leg will act as the control.
Control group
Active

Outcomes
Primary outcome [1] 274 0
The primary outcome will be changes in foot shape and posture in the treated leg compared to the untreated leg.
This will be measured by Xrays, Foot posture index and Clinical photographs.
Timepoint [1] 274 0
Xrays - taken at baseline, and at conclusion (2 years).
Foot posture index - baseline, then every 6, 12, 18 months and at conclusion.
Clinical photographs - baseline, then every 6, 12, 18 months and at conclusion.
Secondary outcome [1] 613 0
To ensure that the use of botulinum toxin will not have detrimental effects on foot posture and deformity, using:
X-rays – done pre- and post-trial.
Timepoint [1] 613 0
Foot posture index and clinical photographs – done pre-trial , then every 6 months till completion of the trial.

Eligibility
Key inclusion criteria
Children will have a non-fixed bilateral pes cavus due to Charcot Marie Tooth disease type 1A. All patients will have a definite clinical diagnosis of Charcot-Marie-Tooth disease, which will be confirmed where possible by neurophysiologic testing and/or genetic testing of the patient or an affected first-degree relative. The diagnosis of pes cavus will be based upon clinical examination and foot X-rays.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Sealed envelopes prepared in advance
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
There is no stratification. The chief investigator and the physician injecting the botulinum toxin are aware of the leg selection for treatment. The investigators doing the follow-up assessments are blinded to the treated leg. The selection of the limb is done by the chief investigator by coin flip.
Masking / blinding
Blinded (masking used)
