About this study

Official title: Phase 1 Clinical Trial of rAAV2.5-CMV-mini-Dystrophin Gene Vector in Duchenne Muscular Dystrophy

The purpose of this study is to determine the safety of a miniature dystrophin gene in the treatment of progressive muscle weakness due to Duchenne Muscular Dystrophy (DMD).

Read the detailed description

This phase I randomized double blind dose escalation study investigates the safety and efficacy of the mini-dystrophin gene transferred to the biceps muscle for Duchenne muscular dystrophy patients, ages 5 to 12 years of age, using a recombinant adeno-associated virus. Eligible participants must have a known dystrophin gene mutation and may be concurrently treated with corticoid steroids. The mini-dystrophin gene or a placebo agent (normal saline or empty viral capsids) are injected directly into both biceps muscles while under conscious sedation. Following the gene transfer, patients are admitted to the hospital for 48 hours of observation followed by weekly outpatient visits at the Columbus Children's Hospital Neuromuscular Clinic. A bilateral muscle biopsy is preformed following 6 weeks with long term follow up will consisting of bi-annual visits for the next 2 years.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • rAAV2.5-CMV-minidystrophin (d3990)Biological

    Recombinant adeno-associated virus (AAV) carrying a truncated human dystrophin gene (mini-dystrophin) expressed from a cytomegalovirus (CMV) promoter.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants with Adverse Events as a Measure of Safety and Tolerability

    Physical Exams assessing major organ systems and safety labs (GGT, Bilirubin, Glucose, Amylase, CBC/Diff, AFP, Platelets, PT/PTT, Creatinine, Electrolytes, Total protein, Alkaline phosphatase, and Urinalysis)

    Measured: followed for 2 years post injection

Secondary outcomes (2)
  1. mini-dystrophin gene expression at the site of gene transfer

    Measured: 90 days post injection

  2. Maximal Volume Isometric Contraction Testing as a measure of muscle strength

    Measured: out to 2 years post injection

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing rAAV2.5-CMV-minidystrophin (d3990) in people with Duchenne Muscular Dystrophy, run by Nationwide Children's Hospital at 1 site in United States.

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 5 inclusion and 5 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: finished, as of the sponsor's last update on 5 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Number of Participants with Adverse Events as a Measure of Safety and Tolerability (time frame: followed for 2 years post injection). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00428935, which also lists 4 linked publications.

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 5 Feb 2013.
