Key inclusion & exclusion criteria
|
Inclusion Criteria:
- In the opinion of the investigator, the subject is capable of understanding and
complying with protocol requirements.
- The subject or, when applicable, the subject's legally acceptable representative signs
and dates a written, informed consent form and any required privacy authorization
prior to the initiation of any study procedures.
- If above the age of 7, the subject signs and dates a written, informed assent form
(IAF) and any required privacy authorization prior to the initiation of any study
procedures.
- The subject must have confirmed diagnosis of Duchenne Muscular Dystrophy defined as
muscle biopsy and dystrophin analyses consistent with DMD or DNA mutation and analysis
by PCR or Southern blot techniques to detect gene deletions as well as:
1. onset of weakness before 5 years of age;
2. proximal muscle weakness;
3. increased serum creatine kinase more than 10 times the upper limit of normal
(ULN);
- The subject is male and aged 4 to 16 years, inclusive.
- The subject weighs at least 13 kg and has a Body Mass Index (BMI) of = 40.
- Willingness and ability to comply with scheduled visits, oral drug administration, and
study procedures including blood sample draws (total blood volume collected not to
exceed 50 mL for the study duration or 25 mL on any single study day [= 3 mL/kg])
- The subject has a life expectancy of >1 year.
- Up to date on all childhood vaccinations, specifically varicella vaccine (chicken
pox).
- Baseline health is judged to be stable based on medical history, physical examination,
laboratory profiles, vital signs, or ECGs at screening, as deemed by the Investigator.
- Continuous non smoker who has not used nicotine containing products for at least 3
months prior to the first dose.
- The subject is able to take tablets.
Exclusion Criteria:
- The subject has received any investigational compound and/or has participated in
another clinical study within 90 days prior to study treatment with the exception of
observational cohort studies or non-interventional studies.
- The subject has received deflazacort within 30 days or previous discontinued
deflazacort due to an intolerable reaction.
- The subject is an immediate family member, study site employee, or is in a dependent
relationship with a study site employee who is involved in the conduct of this study
(e.g. spouse, parent, child, sibling) or may consent under duress.
- Any significant finding on the Columbia suicide severity rating scale (C SSRS) for
subjects (ages 12-16, inclusive), in the opinion of the PI, warrants exclusion from
this study.
- The subject has, in the judgment of the investigator, clinically significant abnormal
clinical chemistry laboratory parameters that may affect safety at Screening.
- The subject has, in the judgment of the investigator, a history or current medical
condition that could affect safety including, but not limited to:
1. Major renal or hepatic impairment
2. Immunosuppression or other contraindications for corticosteroid treatment
3. History of chronic systemic fungal or viral infections
4. Diabetes mellitus
5. Idiopathic hypocalcuria
6. Symptomatic cardiomyopathy at screening
- The subject has a history of hypersensitivity or allergic reaction to steroids or
their formulations including, but not limited to lactose, sucrose, etc.
- Inability to take tablets as assessed by site investigator.
- Unable to refrain from or anticipates the use of:
- Any medications at least 4 hours before and after dosing on PK Days 1 and 8.
- Any vitamins, vitamins with minerals, and/or meal supplementation (e.g., Ensure,
Boost, etc.) at least 4 hours before and after dosing on PK Days 1 and 8.
- Any drug, including prescription and non prescription medications, and herbal
remedies known to be significant inhibitors of CYP 3A4 enzymes and/or P gp for 14
days prior to the first dose of study drug and throughout the study. Appropriate
sources will be consulted by the PI or designee to confirm lack of
pharmacokinetic/pharmacodynamic interaction with study drug. Acetaminophen may be
permitted during the study (doses to be based upon appropriate age/weight ranges.
- Any drugs known to be significant inducers of CYP 3A4 enzymes and/or P gp for 28
days prior to the first dose of study drug and throughout the study. Appropriate
sources will be consulted by the PI or designee to confirm lack of
PK/pharmacodynamics interaction with study drug.
- Subject is mentally or legally incapacitated or has significant emotional problems at
the time of screening visit or expected during the conduct of the study.
- History of any illness that, in the opinion of the PI, might confound the results of
the study or poses an additional risk to the subject by their participation in the
study.
- Positive urine drug or alcohol results at screening or check in.
- Positive urine cotinine at screening.
- Positive results at screening for HIV, HBsAg, or HCV.
- Hemoglobin level below the lower limit of normal at screening.
- Donation of blood or significant blood loss within 56 days prior to the first dose of
study drug.
