Duchenne Muscular Dystrophy | Drug: Prednisone Drug: Deflazacort | Phase 3 |
Boys with Duchenne muscular dystrophy experience progressive muscle weakness as they grow up. Corticosteroids are currently the only medicine that has been shown to increase muscle strength in boys with DMD. Benefits include an increase in the length of time that boys could continue to walk, reduction in the development of curvature of the spine, a longer time of adequate breathing, and possible protection against the development of heart problems.
Doctors have tried different ways of prescribing corticosteroids in order to decrease undesirable side effects of the drug. No controlled, long-term study has ever looked at the effects of different corticosteroids to see which one improves strength the most and which one causes the fewest side effects, over a period of time. Different doctors in different countries prescribe the drugs in different ways, and some do not prescribe corticosteroids at all.
The FOR DMD study will enroll boys with DMD ages 4-7. The study will look at three ways of taking the following corticosteroids by the mouth to determine which increases muscle strength the most, and which causes the fewest side effects:
- Prednisone 0.75mg/kg/day
- Prednisone 0.75mg/kg/day switching between 10 days on and 10 days off treatment
- Deflazacort 0.9mg/kg/day.
The study will take place at 40 academic medical centers in the United States, Canada, United Kingdom, Germany and Italy.

- Forced Vital Capacity [ Time Frame: Average of Months 3, 6, 12, 18, 24, 30 and 36 visits ]Forced vital capacity was measured during a spirometry test. Forced expiratory volume (FEV) measures how much air a person can exhale during a forced breath. Forced vital capacity (FVC) is the total amount of air exhaled during the FEV test.
- Rise From the Floor Velocity [ Time Frame: Average of Months 3, 6, 12, 18, 24, 30 and 36 visits ]Reciprocal of time to rise from the floor
- Treatment Satisfaction Questionnaire for Medication (TSQM) Global Satisfaction With Treatment Score [ Time Frame: Average of Months 3, 6, 12, 18, 24, 30 and 36 visits ]The TSQM Global Satisfaction with Treatment is a 14-item questionnaire that ranges from 0 - 100 with higher scores indicating better outcomes.
- North Star Ambulatory Assessment (NSAA) Score [ Time Frame: Average of Months 3, 6, 12, 18, 24, 30 and 36 visits ]
The North Star Ambulatory Assessment (NSAA) is a 17-item rating scale that is used to measure functional motor abilities in ambulant children with Duchenne Muscular Dystrophy (DMD). It is usually used to monitor the progression of the disease and treatment effects.
The activities are graded as follows:
2 - "Normal" - no obvious modification of activity
1 - Modified method but achieves goal independent of physical assistance from another 0 - Unable to achieve independently This scale is ordinal with 34 as the maximum score indicating fully-independent function.
- 6 Minute Walk Test [ Time Frame: Average of Months 3, 6, 12, 18, 24, 30 and 36 visits ]Measures the total distance walked in 6 minutes averaged over all post-baseline follow-up visits through Month 36.
- Range of Motion (Goniometry) of Left Ankle [ Time Frame: Average of Months 3, 6, 12, 18, 24, 30 and 36 visits ]Range of motion at the ankle joint in dorsiflexion measured in degrees from plantigrade averaged over all post-baseline visits.
- Range of Motion (Goniometry) of Right Ankle [ Time Frame: Average of Months 3, 6, 12, 18, 24, 30 and 36 visits ]Range of motion at the ankle joint in dorsiflexion measured in degrees from plantigrade averaged over all post-baseline visits.
- Number of Participants Who Tolerated the Regimen [ Time Frame: 3 years ]The number of participants who completed 36 months of follow-up on the originally assigned dosage (for weight) of study medication.
- Heart Rate [ Time Frame: 36 months ]Measured by trans-thoracic echocardiogram and 12-lead ECG.
- Quality of Life - Parent [ Time Frame: Average of Months 12, 24, and 36 visits ]Quality of life was measured by parent/guardian self-report for all children utilizing the PEDSQL measurement tool. This is a 23-question tool. Scores can range from 0 to 100, with higher scores indicating better quality of life for the child.
- Quality of Life- Child [ Time Frame: Average of Months 12, 24, and 36 visits ]Quality of life was measured by child self-report in children age 5 and older utilizing the PEDSQL measurement tool. This is a 23-question tool. Scores can range from 0 to 100, with higher scores indicating better quality of life.
- Left Ventricular Ejection Fraction Percent [ Time Frame: 36 months ]Measured by trans-thoracic echocardiogram and 12-lead ECG.
- Fractional Shortening Percent [ Time Frame: 36 months ]Measured by trans-thoracic echocardiogram and 12-lead ECG.
- PR Interval [ Time Frame: 36 months ]Measured by trans-thoracic echocardiogram and 12-lead ECG.
- Participant Weight [ Time Frame: 36 months ]
- Participant Height [ Time Frame: 36 months ]
- Participant Body Mass Index [ Time Frame: 36 months ]
