Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
1. Participant's parent or legal guardian has provided written informed consent/HIPAA
authorization prior to any extension study-specific procedures;

2. Participant has previously completed study VBP15-002 up to and including the Week 4
Follow-up assessments within 8 weeks prior to enrollment; and

3. Participant and parent/guardian are willing and able to comply with scheduled visits,
study drug administration plan, and study procedures.
Minimum age
4 Years
Maximum age
7 Years
Sex
Males
Can healthy volunteers participate?
No
Key exclusion criteria
1. Participant had a serious or severe adverse event in study VBP15-002 that, in the
opinion of the Investigator, was probably or definitely related to vamorolone use and
precludes safe use of vamorolone for the subject in this study;

2. Participant has current or history of major renal or hepatic impairment, diabetes
mellitus or immunosuppression;

3. Participant has current or history of chronic systemic fungal or viral infections;

4. Participant has used mineralocorticoid receptor agents, such as spironolactone,
eplerenone, canrenone (canrenoate potassium), prorenone (prorenoate potassium),
mexrenone (mexrenoate potassium) within 4 weeks prior to the first dose of study
medication;

5. Participant has evidence of symptomatic cardiomyopathy. [Note: Asymptomatic cardiac
abnormality on investigation would not be exclusionary];

6. Participant is currently being treated or has received previous treatment with oral
glucocorticoids or other immunosuppressive agents. [Notes: Past transient use of oral
glucocorticoids or other oral immunosuppressive agents for no longer than 3 months
cumulative, with last use at least 3 months prior to first dose of study medication,
will be considered for eligibility on a case-by-case basis. Inhaled and/or topical
corticosteroids prescribed for an indication other than DMD are permitted but must be
administered at stable dose for at least 3 months prior to study drug administration];

7. Subject has used idebenone within 4 weeks prior to the first dose of study medication;

8. Participant has an allergy or hypersensitivity to the study medication or to any of
its constituents;

9. Participant has severe behavioral or cognitive problems that preclude participation in
the study, in the opinion of the Investigator;

10. Participant has previous or ongoing medical condition, medical history, physical
findings or laboratory abnormalities that could affect safety, make it unlikely that
treatment and follow-up will be correctly completed or impair the assessment of study
results, in the opinion of the Investigator; or

11. Participant is currently taking any investigational drug, or has taken any
investigational drug other than vamorolone within 3 months prior to the start of study
treatment.

Note: Participants may be re-evaluated if ineligible due to a transient condition which
would prevent the subject from participating

Summary
Brief summary
The main purposes of this study are to see if it is safe to use a new medication called
vamorolone for more than two weeks in children with Duchenne muscular dystrophy (DMD), to see
if vamorolone works for the treatment for DMD, and to see how any potential side effects
compare to those seen in boys using steroids.
