| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
To assess the PK, safety and tolerability of GSK2402968 after a single subcutaneous
 administration at different dose levels in non-ambulatory subjects with Duchenne
 muscular dystrophy. | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
 | 
| E.2.3 | Trial contains a sub-study  |  No  | 
| E.3 | Principal inclusion criteria  | 
Subjects eligible for enrolment in the study must meet all of the following criteria:
 
 1. Duchenne muscular dystrophy resulting from a mutation in the DMD gene, confirmed by a sponsor approved DNA diagnostic technique covering all DMD gene exons, including but not limited to MLPA (Multiplex Ligation-dependent Probe
 Amplification), CGH (Comparative Genomic Hybridisation), SCAIP (Single
 Condition Amplification/Internal Primer) or H-RMCA (High-Resolution Melting
 Curve Analysis), and correctable by treatment with GSK2402968.
 2. Age 9 years old or greater at Screening;
 3. Male;
 4. Non-ambulant (at least 1 year in a wheelchair) within the last 4 years;
 5. Life expectancy at least three years;
 6. Willingness and ability to comply with all protocol requirements and procedures;
 7. QTc <450msec (based on single or average QTc value of triplicate ECGs obtained
 over a brief recording period). Note: QTc may be either QTcB or QTcF, machine
 read or manual overread;
 8. Informed assent and/or consent in writing signed by the subject and/or parent(s)/legal guardian (according to local regulations).
 9. In France, a subject will be eligible for inclusion in this study only if either affiliated
 to or a beneficiary of a social security category.
 
 | 
 
 
 | 
| E.4 | Principal exclusion criteria | 
Subjects meeting any of the following criteria must not be enrolled in the study:
 1. Any additional mutation (such as an additional missing exon for DMD) that cannot
 be treated with GSK2402968;
 2. Current or history of liver or renal disease;
 3. Acute illness within 4 weeks of anticipated administration of study medication,
 which may interfere with study assessments;
 4. Daytime ventilator-dependency (except for daytime naps);
 5. Use of anticoagulants, antithrombotics or antiplatelet agents, previous treatment with investigational drugs, within 6 months of the first administration of study
 medication; and idebenone or other forms of Coenzyme Q10 within 1 month of study
 medication.
 6. Start of glucocorticosteroids within 6 months or non-stable use of
 glucocorticosteroids within 3 months of the anticipated first administration of study
 medication;
 7. Positive hepatitis B surface antigen (HbsAg), hepatitis C antibody test (HCV), or
 human immunodeficiency virus (HIV) test at Screening;
 8. Symptomatic cardiomyopathy;
 9. Use of alcohol from Screening through to the 1 month Follow-up visit (Day 29-35,
 inclusive);
 10. Any Child in Care. (The definition of a Child in Care is a child who has been placed
 under the control or protection of an agency, organization, 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). |
