E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the safety and tolerability of eteplirsen administered once weekly by intravenous (IV) infusion in male Duchenne muscular dystrophy (DMD) patients ages 6 months to 48 months, inclusive |
|
E.2.2 | Secondary objectives of the trial |
To determine the pharmacokinetics (PK) of eteplirsen at the 2-, 10-, 20 and 30-mg/kg dose levels, administered once weekly by IV infusion in male DMD patients ages 6 months to 48 months, inclusive |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Be a male between 6 months to 48 months of age, inclusive. 2. Have an established clinical diagnosis of DMD with a deletion mutation amenable to exon 51 skipping (eg, deletions of exons 45-50, 47-50, 48-50, 49-50, 50, 52, 52-63). 3. Have a parent(s) or legal guardian(s) who is able to understand and comply with the study requirements and is willing to provide written informed consent for the patient to participate in the study. |
|
E.4 | Principal exclusion criteria |
1. Has received any pharmacologic treatment that might have an effect on muscle strength or function within 12 weeks prior to dosing at Week 1 (eg, growth hormone, anabolic steroids). 2. Has received previous or current treatment with any experimental treatment. Prior drisapersen therapy is permitted if a patient has not received drisapersen for 6 months prior to the Week 1 dose. 3. Has a clinically significant illness other than DMD, including cardiac, pulmonary, hepatic, renal, hematologic, immunologic, behavioural disease, or malignancy likely to impair the patient’s ability to participate in this study. 4. Has a clinically significant laboratory abnormality that is either not expected or is of a greater severity than what is expected in DMD patients. 5. Has any other condition that, in the Investigator’s opinion, could interfere with the patient’s participation in the study. |

E.5 End points |
E.5.1 | Primary end point(s) |
Safety and tolerability of eteplirsen as measured by: • Incidence of adverse events (AEs) • Abnormal changes from Baseline or clinically significant worsening of clinical safety laboratory abnormalities (hematology, chemistry, coagulation, and urinalysis) • Abnormal changes from Baseline or worsening of vital signs • Abnormal changes from Baseline or worsening of physical examination findings • Abnormal changes from Baseline or clinically significant worsening of ECGs and ECHOs |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Incidence of AEs: continous Clinical safety laboratory sample: Screening, Weeks 2, 4, 8, 12, 24, 36, 48, 60, 72, 84, 96 and End-of-Study Follow-up Visit Vital signs: Screening, baseline, on weekly infusion days, Week 96 and End-of-Study Follow-up Visit Physical examination: Screening, baseline, Weeks 4, 8, 12, 16, 20-48, 60, 72, 84, 96 and End-of-Study Follow-up Visit ECG: Screening, Weeks 8, 12, 24, 36, 48, 60, 72, 84, 96 ECHO: Screening, Weeks 8, 12, 24, 36, 48, 60, 72, 96 |
|
E.5.2 | Secondary end point(s) |
PK of eteplirsen by population PK methods, including assessment of the following PK parameters (if evaluable): • Maximum plasma concentration (Cmax) • Time of Cmax (Tmax) • AUC • Apparent volume of distribution at steady state (Vss) • Clearance (CL) • Elimination half-life (t½) • Amount of drug eliminated in urine (Ae%) |
|
