Who may be able to join
- 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 Subjects are required to be withdrawn from DMD115501 to participate.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

- 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).

About this study
Official title: A Continued Access Protocol for Eligible US Subjects With Duchenne Muscular Dystrophy Who Previously Participated in an Approved Drisapersen Study
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.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Drisapersen in people with Muscular Dystrophies, run by GlaxoSmithKline.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 24 Mar 2014. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Safety as assessed by the collection of adverse events (AEs) (time frame: Baseline to Week 48). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Mar 2014.
