Arm Intervention/treatment
Experimental: Olesoxime

Participants who have consented to the dose increase will receive 10 milligrams per kilogram (mg/kg) suspension twice a day (BID) either orally or via a naso-gastric or gastrostomy tube with breakfast and dinner, preferably at the same time of the day throughout the study. If the drug administration does not coincide with one of the scheduled meals, a snack should be taken prior to drug administration. Preferably there should be at least 10 hours between the morning and evening dose. The total dose in this study will not exceed 2000 mg.

Participants who do not consent to the dose increase will continue with the previous dosage and receive a dose of 10 mg/kg suspension once a day orally or via a naso-gastric or gastronomy tube with the main meal, preferably at the same time of the day.

 Drug: Olesoxime
Participants will receive homogeneous suspension of olesoxime.


Outcome Measures

Primary Outcome Measures :
  1. Percentage of Participants With Adverse Events (AEs) or Serious Adverse Events (SAEs) [ Time Frame: Baseline up to approximately 3 years ]

Secondary Outcome Measures :
  1. Change From Baseline in Motor Function Measure (MFM) Dimension 1 (D1) + Dimension 2 (D2) Score [ Time Frame: Baseline (Week 1), Weeks 26, 52, 78, 104 and 130 ]
    The MFM scale evaluated motor function in three dimensions. D1 evaluates functions related to standing and transfer, D2 evaluates axial and proximal function in supine and sitting position on mat and chair and D3 evaluates distal motor function. The scoring of each task uses a 4-point Likert scale based on the participant's maximal abilities without assistance: 0, cannot initiate the task or maintain the starting position; 1, performs the task partially; 2, performs the task incompletely or imperfectly (with compensatory/uncontrolled movements or slowness); and 3, performs the task fully and "normally". The scores are summed to yield a total score expressed as the percentage of the maximum possible score (the one obtained with no physical impairment); the lower the total score, the more severe the impairment.

  2. Change From Baseline in MFM Total Score (D1+ D2 + Dimension 3 [D3]) Score [ Time Frame: Baseline (Week 1), Weeks 26, 52, 78, 104 and 130 ]
    The MFM scale evaluated motor function in three dimensions. D1 evaluates functions related to standing and transfer, D2 evaluates axial and proximal function in supine and sitting position on mat and chair and D3 evaluates distal motor function. The scoring of each task uses a 4-point Likert scale based on the participant's maximal abilities without assistance: 0, cannot initiate the task or maintain the starting position; 1, performs the task partially; 2, performs the task incompletely or imperfectly (with compensatory/uncontrolled movements or slowness); and 3, performs the task fully and "normally". The scores are summed to yield a total score expressed as the percentage of the maximum possible score (the one obtained with no physical impairment); the lower the total score, the more severe the impairment.

  3. Plasma Concentrations of Olesoxime [ Time Frame: Pre-dose (Hour 0) at Weeks 1, 13, 26, 39, 52, 78, 104 and 130 ]

  4. Change From Baseline in Pediatric Quality of Life Questionnaire (PedsQL) Generic Core Scale Version 4.0 Score [ Time Frame: Baseline (Week 1), Weeks 26, 52, 78, 104 and 130 ]
    The PedsQL Generic Core Scale includes 23 items using self-report and/or parent report (ages 5+). The instrument covers physical, emotional, social and school functioning. Scale items are linearly transformed to a 0-100 scale (0 = 100, 1 = 75, 2 = 50, 3 = 25, and 4 = 0) so that higher scores indicate better health related quality of life.

  5. Change From Baseline in Caregiver PedsQL Generic Core Scales Version 4.0 Score [ Time Frame: Baseline (Week 1), Weeks 26, 52, 78, 104 and 130 ]
    The PedsQL Generic Core Scale includes 23 items. The instrument covers physical, emotional, social and school functioning. Scale items are linearly transformed to a 0-100 scale (0 = 100, 1 = 75, 2 = 50, 3 = 25, and 4 = 0) so that higher scores indicate better health related quality of life. Questionnaire was completed by the caregiver.

  6. Change From Baseline in PedsQL Neuromuscular Module Version 3.0 Scale Score [ Time Frame: Baseline (Week 1), Weeks 26, 52, 78, 104 and 130 ]
    The PedsQL Neuromuscular Module (Version 3.0) includes 25 items using self-report (ages 5 - 18) and/or parent report (ages 5 -18). The instrument covers problems related to neuromuscular disease, communication and family resources. Scale items are linearly transformed to a 0-100 scale (0 = 100, 1 = 75, 2 = 50, 3 = 25, and 4 = 0) so that higher scores indicate better health related quality of life.

  7. Change From Baseline in Caregiver PedsQL Neuromuscular Module Version 3.0 Scale Score [ Time Frame: Baseline (Week 1), Weeks 26, 52, 78, 104 and 130 ]

    The SF-36 was used to assess health-related quality of life at baseline and at on-treatment visits. The SF-36 consisted of 36 questions covering 8 domains (physical functioning, role-functioning physical, bodily pain, general health, vitality, social functioning, role-functioning emotional and mental health), with each domain scoring on a scale 0-100 (a score of 0 = maximum disability and a score of 100 = no disability). The 8 domains are further summarized to 2 distinct higher-ordered clusters: the physical and mental composite t-scores (PCS and MCS). The range for all 8 domains as well as for the composite norm-based t-scores is from 0 to 100 with 100 as best possible health status and 0 as worst health status. Reported here are the Physical Composite Scores (PCS) and Mental Composite Scores (MCS).

The range for all 8 norm-based domains was from 0 to 100 with 100 as best possible health status and 0 as worst health status.

  18. Change From Baseline in Revised Utility Index Score (SF-6D_R2): Caregiver [ Time Frame: Baseline (Week 1), Weeks 26, 52, 78, 104 and 130 ]
    The SF-6D focuses on seven of the eight health domains covered by the SF-36: physical functioning, role participation (combined role-physical and role-emotional), social functioning, bodily pain, mental health, and vitality. SF-6D Health Utility Index (HUI) Score = 0 (worst measured health state) to 1 (best measured health state).

  19. SMA Independence Scale (SMAIS) Score: Patient [ Time Frame: Week 104 and Week 130 ]
    The SMAIS was developed specifically for SMA in order to assess function-related independence. The SMAIS contains 29 items, assessing the amount of assistance required from another individual to perform daily activities, such as eating or transferring to/from a wheelchair. Each item is scored on a zero to four scale (with an additional option to indicate that an item is non-applicable). Item scores are summed to create the total score. The range of total score is between 0 and 116. Lower scores indicate greater dependence on another individual.
