Arms and Interventions

Arm Intervention/Treatment
Experimental: Deflazacort

Participants will receive deflazacort 0.6 milligrams per kilograms per day (mg/kg/day) orally. The dose could be reduced in case of tolerability issues. Any participant assigned to placebo prior to the Version 4.0 amendment (prior to or after 01 February 2020) will have the option to be consented under Version 4.0 and will be switched to deflazacort for 26 weeks treatment. Any participant assigned to deflazacort prior to the Version 4.0 amendment (prior to 01 February 2020) will have the option to re-consent under Protocol Version 4.0 and continue for an additional 26 weeks treatment. Any participant assigned to deflazacort prior to the Version 4.0 amendment (after 01 February 2020) will have the option to re-consent under Protocol Version 4.0 at their Week 13 Visit and continue treatment until Week 26. Any new participant enrolled until 31 May 2020 will receive deflazacort for 26 weeks.

Drug: Deflazacort
Deflazacort tablet will be administered as per the dose and schedule specified in the arm.

    Participant Flow

    Recruitment Details
    Pre-assignment Detail Participants enrolled under protocol v3.0 were 1:1 randomized to get placebo or deflazacort. After protocol v4.0, the study became an open-label study and all participants received deflazacort. Per planned analysis, participants who took at least 1 dose of deflazacort were pooled in the safety and efficacy summaries.
    Arm/Group Title Deflazacort Placebo
    Arm/Group Description Participants received deflazacort tablets, administered orally once daily at a target dose of 0.6 milligrams (mg)/kilograms (kg)/day for 26 weeks in placebo-controlled period and for 26 weeks in open-label extension period. Participants received placebo matched to deflazacort tablets, administered orally once daily for 26 weeks in placebo-controlled period. Participants were then transitioned to receive deflazacort tablets, administered orally once daily at a target dose of 0.6 mg/kg/day for 26 weeks in open-label extension period.
