Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

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

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
to assess whether zoledronic acid 0.025mg/kg/dose as an intravenous preparation infused over 30 minutes, at 0,3 months then 0.05mg/kg/dose at 6,12 and 18 months is superior to calcium as an oral tablet plus vitamin D as orally administered capsule, to improve bone density and reduce fracture risk in boys with Duchenne muscular dystrophy

Eligibility
Key inclusion criteria
All boys between 6-16 years with confirmed Duchenne Muscular Dystrophy (DMD) and who are receiving glucocorticoid therapy (this is universally prednisolone)
Minimum age
6 Years
Maximum age
16 Years
Sex
Males
Can healthy volunteers participate?
No
Key exclusion criteria
Genant Grade 3 or greater vertebral compression
1. Any prior use of osteoporosis or bone-modifying therapy, such as bisphosphonates, sodium fluoride, calcitonin, calcitriol, Gonadotrophin releasing hormone agonists or Growth Hormone (GH).
2. Patients who have received testosterone therapy may only be included in the trial if this therapy was given as part of physiological replacement in the setting of documented hormonal deficiencies
3. Any prior history of malignancy
4. Any medical condition that might interfere with the evaluation of LS BMD, such as severe scoliosis or spinal fusion. Patients with less than 3 evaluable vertebrae by DEXA evaluation in the region of interest (ROI) L1-L4, as confirmed by the central imaging laboratory, will not be considered eligible for this study.
5. Hypocalcemia and hypophosphatemia: any value (age-matched) below the normal range at screening
6. Vitamin D deficiency (serum 25-hydroxy vitamin D concentrations of < 50 nmol/L) at screening
7. Renal impairment: Glomerulr filtration rate (GFR) < 35 ml/min/1.73 m2 at screening based on the Schwartz formula.
8. A serum creatinine increase between Visit 1 and Visit 2 greater than 44.2 mmol/L
9. History of hyperparathyroidism, hypothyriodism or hyperthyroidism within 1 year of screening
10.History of sarcoidosis, primary bone disease (osteogenesis imperfecta, idiopathic juvenile
osteoporosis, rickets/osteomalacia)., Kawasaki’s disease or Henoch-Schonlein Purpura.
11. Diagnosis of active uveitis (symptomatic or asymptomatic) at the time of enrollment of the study.
12. Any subject involved in another study, if an investigational agent is deemed by investigators to possible interfere with this study agent. ( for example use of a different bisphosphonate or a statin, a drug that utilizes the same biochemical pathways )

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will be achieved using minimisation (a highly efficient method accounting for strataespecially when the sample sizes are small), with strata being treating centre and age (young: 4- 8yrs ,older: 9-13 and 14-18). Such stratification will group changes in bone quality due in part to pubertal status- pre, peri and post pubertal. . This, together with minimisation will ensure allocation concealment for the study
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be achieved via a web based system from the National Health and Medical Research Council (NHMRC) Clinical Trials Centre
