Duchenne Muscular DystrophyPhase 1NCT02835079
Treatment Effect of Tamoxifen on Patients With DMD
A Phase 1 study testing Tamoxifen in people with Duchenne Muscular Dystrophy, run by Hadassah Medical Organization.
Trial summary
Duchenne muscular dystrophy (DMD) is a progressive devastating disease that affects mainly boys, with an incidence of about 1:3,500 live births. The pathology of DMD is a result of non-repaired muscle damage that leads to muscle-tissue replacement by scar tissue, a process known as fibrosis. Read more about this study

About this study
Duchenne muscular dystrophy (DMD) is a progressive devastating disease that affects mainly boys, with an incidence of about 1:3,500 live births. The pathology of DMD is a result of non-repaired muscle damage that leads to muscle-tissue replacement by scar tissue, a process known as fibrosis. Currently, there is no effective treatment for the disease. The only therapy offered to these boys are steroids which slightly delayed the disease progression. The boys lose their ability to walk at around the age of 12, and die in the 4th decade of life from severe heart and lung problems.
In this study investigators will test the efficacy of Tamoxifen treatment in ambulatory DMD boys. Tamoxifen is a drug used for palliative treatment of breast cancer patients and has an outstanding safety profile. In addition, Tamoxifen was tested in the past in boys, for other pediatric indications, and showed an excellent safety with no side effects.

Tamoxifen is being tested in this study, as a therapy for DMD, for the following reasons:
(i) it was shown to have anti-fibrotic effect in multiple in-vivo systems; (ii) it assists in the repair of damaged muscles.
In other words, Tamoxifen is expected to have a synergistic effect on DMD patients, due to its dual mechanism of action. Indeed, Tamoxifen was shown to have significant beneficial effects in the mdx mouse model of DMD. Also, a small compassionate cohort of 3 boys, treated for 6 months with Tamoxifen, yielded very encouraging results.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Duchenne muscular dystrophy (DMD) is a progressive devastating disease that affects mainly boys, with an incidence of about 1:3,500 live births.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Tamoxifen in people with Duchenne Muscular Dystrophy, run by Hadassah Medical Organization.
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 1 inclusion and 1 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 25 Jul 2022. 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 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?
6-minute walk distance (6MWD) (time frame: The six minute walk distance will be tested during the 36 months of the trial. For the first 12 months, the 6 minute walk test will be tested every 3 months and for the follow up period of 24 months,will be done every 6 months.). 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 NCT02835079, which also lists 1 linked publication.
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 25 Jul 2022.
