General information about the trial
|
|||
Main objective of the trial |
The primary objective was to determine the safety and tolerability of single and multiple oral doses of SMT C1100 in patients with Duchenne Muscular Dystrophy (DMD).
|
||
Protection of trial subjects |
Following discussion of the study with study site personnel, the patient’s parents/legal guardians signed a study-specific informed consent form in the presence of a study site physician or a suitably trained deputy to indicate that they were freely giving their informed consent. An age-specific informed assent form was reviewed with the patient by the site personnel and the patient’s parents/legal guardians. Written or verbal assent of the patient was considered for inclusion and was documented within the patient medical notes.
A safety review was performed following each initial dosing, and there was a 48 hour period between dosing of each patient. In addition, there was at least 2 weeks between each dose escalation, to allow a satisfactory review of safety, tolerability and pharmacokinetics data. The project team led by the Sponsor’s Chief Medical Officer and Chief Investigator conducted the safety reviews.
|
||
Background therapy |
During the study, systemic corticosteroids (stable dose for 2 months prior to start of study), bisphosphonates, beta blockers, angiotensin-receptor blockers and angiotensin converting enzyme inhibitors were permitted. | ||
Evidence for comparator |

Notes [1] - The number of subjects reported to have started the pre-assignment period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same. Justification: Thirteen patients were screened for inclusion in the study, however one patient was excluded as a screen failure. Twelve patients were dosed with SMT C1100, and data are reported for these patients. |
