Exclusion Criteria

Subjects who meet one or more of the following criteria are not allowed to be included in the study:
1. Evidence of renal dysfunction, blood dysplasia, hepatic insufficiency, symptomatic

2. Any clinically significant ECG abnormality
3. Any acute co-morbid condition interfering with the well-being of the subject within 7 days of enrolment including bacterial infection, viral infectious processes, food poisoning, temperature > 37.0 °C, the need for acute treatment or observation due to any other reason, as judged by the investigator; patient can be included after resolution of the acute event

Subjects who use a nebulizer or require an inhaler to steroids will be allowed in the study; however oral use of steroids is prohibited.
The oral use of salbutamol is permitted with the following restrictions: patients should have been on salbutamol for at least 6 months before inclusion in the trial, with good tolerance. The dose of salbutamol should remain constant for the duration of the trial. The use of inhaled ß-agonists (for the treatment of asthma crisis for example) is allowed.
5. Spinal rod or fixation for scoliosis within the past 6 months or anticipated need of rod or fixation within 6 months of enrolment.
6. Inability to meet study visit requirements or cooperate reliably with functional testing
7. Coexisting medical conditions that contraindicate travel, testing or study medications
8. Olesoxime is contraindicated in subjects/patients who develop drug hypersensitivity to it or one of the formulation excipients including hypersensitivity to sesame oil.

11. Current or planned pregnancy or nursing period
12. For Women: Failure to use one of the following safe methods of contraception:
