Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1.An intravenous intervention of 0.025mg/Kg Zoledronic Acid (ZA) at each visit, the first being within 4 weeks of screening, then at 3 monthly intervals, (5 doses).
2.The calculated dose of reconstituted ZA will be diluted in 50ml of (0.9%) Normal Saline and infused over 30 minutes. The maximum dose to be given is 2 mg/infusion.
3. Vitamin D 400 International Units (IU) oral capsule supplementation daily for 15 months for duration of study

Outcomes
Primary outcome [1] 258420 0
To determine if 12 months of intravenous zoledronic acid improves femoral head sphericity in children and adolescents with Perthes disease. Deformity Index (DI) using Anteroposterior (AP) radiograph of the pelvis the DI compares the affected hip to the unaffected side. All measurements performed blinded at 24 months by a single observer.
Timepoint [1] 258420 0
At 24 months following randomisation.
Secondary outcome [1] 264192 0
To determine if 12 months of intravenous zoledronic acid improves hip function and pain in children and adolescents with Perthes disease. Assessment using the modified Harris Hip Score and Faces Pain Scale.
Timepoint [1] 264192 0
Baseline, 3,6,9,12,18 and 24 months visits.
Secondary outcome [2] 264193 0
To determine the safety of 12 months of intravenous zoledronic acid in children and adolescents with Perthes disease. Measured by: 1. Biochemistry and Haematology: urea, electrolytes, creatinine, calcium, magnesium, phosphorus and full blood count. Urine-Beta Human Chorionic Gonadotropin or Pregnancy Test (BHCG). Analysis will occur at the local treatment centre and be performed only on the intervention group (B) Mineral homeostasis and Bone turnover markers: 25-hydroxyvitamin D, parathyroid hormone (PTH), Serum Osteocalcin, Bone Specific Alkaline Phosphatase, aminoterminal propeptide of type 1 procollagen (P1NP), serum collagen-type I Ntelopeptides (NTX). These will be performed in both intervention (Group B) and control group (Group A) 2. Dual energy X-ray Absorptiometry (DXA scan): Lumbar spine, total body and bilateral femoral neck will be assessed. The magnitude of any increase in bone mass from ZA will be recorded. If age matched z-score for total body or lumbar spine becomes >3.0 ZA therapy will be discontinued. These will be performed in both intervention (Group B) and control group. (Group A) 3. Bone Age: There is a known delay in bone age in Perthes Disease. Radiographs will be evaluated by a single investigator. This will be performed in both intervention (Group A) and control group Group B) 4. Pelvic X-Ray.This will be performed in both intervention (Group A) and control group Group B) 4. Auxology: Height and Weight
Timepoint [2] 264193 0
Biochemistry and Haemotology: Baseline, 6,12 and 24 months visit. DXA Scan: Baseline, 12 and 24 months visit. Bone Age: Baseline, 12 and 24 months visit. X-Ray: Baseline,,12 and 24 months visit. Height and Weight: Baseline, 6,12 and 24 months visit.
Secondary outcome [3] 264194 0
To determine the Quality of Life of 12 months of intravenous zoledronic acid in children and adolescents with Perthes disease.
Assessment will be made using the Paediatric Outcomes Data Collection Instrument (PODCI)
Timepoint [3] 264194 0
Baseline, 6,12 and 24 months visit.
Secondary outcome [4] 264269 0
Femoral head subluxation (femoral head coverage) Extrusion can be measured as a percentage measured by AP X-ray.
Timepoint [4] 264269 0
At 24 months.

No
Key exclusion criteria
Diagnosis of Avascular Necrosis of the femoral head not due to Perthes Disease.
Previous treatment of bisphosphonates.
Current pregnancy or sexually active and not using a medically acceptable form of birth control.
Untreated rickets within 1 year of enrolment.
History of clinically significant organic or psychiatric findings on physical examination, which in the opinion of the investigator would prevent the patient from completing the study.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Consent obtained after diagnosis of unlateral Perthes Disease with >50% involvement of the opposite lateral femoral head pillar for randomised treatment into either the a) Standard Care or b) intravenous Zoledronic Acid and Standard Care.
Allocation Concealment procedures using minimisation, with strata being gender, treating centre and age being conducted by phone at central administration site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be achieved via a web based system by the National Health and Medical Research Centre, Clinical Trials Centre.

Summary
Brief summary
This study is a randomised study that will investigate the safety and effacy of intravenous Zoledronic Acid and standard care compared to Standard Care in children and young adolescents, diagnosed with Perthes Disease.
The hypothesis is that 12 months of intravenous zoledronic acid will retard femoral head collapse resulting in: improved femoral head sphericity at 24 months and improved hip function and reduced hip pain at 24 months
