Trial overview
Official title: An exploratory study to assess two doses of GSK2402968 in the Treatment of Ambulant boys with Duchenne Muscular Dystrophy
Trial description: The purpose of this study is to determine if GSK2402968 is effective in the treatment of ambulant boys with Duchenne muscular dystrophy resulting from a mutation thought to be corrected by exon 51 skipping. Two doses of GSK2402968 and placebo will be used in this study.

- Males, aged at least 5 years,
- Life expectancy of at least 1 year,
- Able to rise from floor in < or =15 seconds (without aids/orthoses) at Screening Visit 1 and Screening Visit 2,

- Receiving oral glucocorticoids for a minimum of 6 months immediately prior to screening, with no significant change in total daily dosage or dosing regimen for a minimum of 3 months immediately prior to screening and a reasonable expectation that total daily dosage and dosing regimen will not change significantly for the 48 week duration of the study (Dose adjustments that are based on weight changes are permitted),
- QTc <450msec (based on single or average QTc value of triplicate ECGs obtained over a brief recording period), or <480 msec for subjects with Bundle Branch Block. Note: QTc may be either QTcB or QTcF, and machine read or manual overread

- Children in Care. The definition of a Child in Care is a child who has been placed under the control or protection of an agency, organisation, institution or entity by the courts, the government or a government body, acting in accordance with powers conferred on them by law or regulation. The definition of a child in care can include a child cared for by foster parents or living in a care home or institution, provided that the arrangement falls within the definition above. The definition of a child in care does not include a child who is adopted or has an appointed legal guardian
