Trial overview
Official title: A Continued Access protocol for eligible US subjects with Duchenne Muscular Dystrophy who previously participated in an approved drisapersen study
Trial description: This is a single arm, open-label continued access protocol of drisapersen for the treatment of male subjects with Duchenne muscular dystrophy (DMD) having dystrophin mutations correctable by drisapersen-induced DMD Exon 51 skipping. The purpose of this continued access protocol is to offer pre-approval access to drisapersen for the treatment of subjects with DMD who previously participated in eligible drisapersen studies. The protocol will collect safety data required to assure subject safety and periodic efficacy data on muscle function.

- Prior DMD114876 subjects: Subjects who completed both the 24 week double-blind treatment and 24 week post-treatment phases in study DMD114876, OR Subjects who withdrew from the treatment portion of study DMD114876 due to meeting laboratory safety stopping criteria may be eligible to enroll in the extension study if: the laboratory parameters that led to stopping have resolved; benefit of further treatment with drisapersen outweighs the risk to the individual subject; and following consultation with the GSK Medical Lead.
- Prior DMD115501 subjects:
- Subject had a serious adverse experience or who met safety stopping criteria that remains unresolved from protocol DMD114876, which in the opinion of the physician conducting this protocol could have been attributable to study medication, and which is ongoing. Once resolved, subject may be eligible to enroll following consultation with the GlaxoSmithKline (GSK) Medical Lead.
- Use of anticoagulants, antithrombotics or antiplatelet agents, or previous treatment with investigational drugs, except for drisapersen, within 28 days of the first administration of drisapersen.

- Prior DMD114876 subjects: Subjects who completed both the 24 week double-blind treatment and 24 week post-treatment phases in study DMD114876, OR Subjects who withdrew from the treatment portion of study DMD114876 due to meeting laboratory safety stopping criteria may be eligible to enroll in the extension study if: the laboratory parameters that led to stopping have resolved; benefit of further treatment with drisapersen outweighs the risk to the individual subject; and following consultation with the GSK Medical Lead.
- Prior DMD115501 subjects:
- Active subjects who entered into open-label extension study DMD115501. Subjects are required to be withdrawn from DMD115501 to participate.
- Prior DMD114044 Subjects: US citizens who completed study DMD114044 in another country and who want to return to the US to participate, upon agreement by a physician conducting this protocol, OR Unites States citizens who participated in DMD114044 but who had to withdraw from the study due to meeting laboratory safety stopping criteria may be eligible to enroll if: the laboratory parameters that led to stopping have resolved; benefit of further treatment with drisapersen outweighs the risk to the individual subject; and following consultation with the GSK Medical Lead and upon agreement of physician conducting this protocol
- Prior DMD114349 Subjects: US citizens who participated in and completed study DMD114044 in another country and who entered into the ongoing open-label extension study DMD114349 in a country outside the US who wish to withdraw from DMD114349 and return to the US to participate in this protocol, upon agreement by a physician conducting this protocol. Subjects are required to withdraw from DMD114349 to participate in this protocol.
- Baseline platelets of 150 x 109/Liters (L) or greater and no history of thrombocytopenia.
- Continued use of glucocorticosteroids for a minimum of 60 days prior to protocol entry with a reasonable expectation that the subject will remain on steroids for the duration of the protocol. Changes to or cessation of glucocorticosteroids will be at the discretion of the physician conducting this protocol in consultation with the subject/parent. The GSK Medical Lead must be notified in a timely manner.
- Willing and able to comply with all protocol requirements and procedures (with the exception of those assessments requiring a subject to be ambulant, for those subjects who have lost ambulation).
- Able to give informed assent and/or consent in writing signed by the subject and/or parent(s)/legal guardian (according to local regulations).
Exclusion criteria:
- Subject had a serious adverse experience or who met safety stopping criteria that remains unresolved from protocol DMD114876, which in the opinion of the physician conducting this protocol could have been attributable to study medication, and which is ongoing. Once resolved, subject may be eligible to enroll following consultation with the GlaxoSmithKline (GSK) Medical Lead.
- Use of anticoagulants, antithrombotics or antiplatelet agents, or previous treatment with investigational drugs, except for drisapersen, within 28 days of the first administration of drisapersen.
