Study Description

Brief Summary:

The primary objective is to study the effect of Denosumab on Bone Mineral Density, Standardised Uptake Value and bone metabolism in patients with total hip arthroplasty. The primary hypothesis is to demonstrate that Denosumab is superior to placebo.

Condition or disease	Intervention/treatment	Phase
Osteoarthritis, Hip; Ambulation Difficulty	Drug: denosumab	Phase 2

Detailed Description:

A clinical study with 64 patients, age 35-65 years, with unilateral osteoarthritis of the hip, randomised to two groups of patients, either receiving Denosumab or placebo

The patients will operated with an uncemented total hip arthroplasty with a Continuum acetabular cup with trabecular surface (Tantalum) and longevity Highly Cross-linked Polyethylene liner, Zimmer, Warsaw, IN, USA, and a CFP femoral stem with Titanium surface and a chrome cobalt 28 mm head, Waldemar Link, Hamburg, Germany.

Clinical outcome evaluated by Harris Hip Score and EQ-5D, Bone Mineral Density by DXA, Standardised Uptake Value of Fluoride tracer, by PET/CT and biochemical markers for bone formation and bone resorption will be analyzed together with conventional radiology for implant position and fixation.

Outcome Measures

Primary Outcome Measures :

1. Bone Mineral Density [ Time Frame: 12 months ]
   Bone mineral density by DXA in Gruen Zone 7 and a sum of Gruen zone 1-7

Secondary Outcome Measures :

1. Bone mineral Density [ Time Frame: 24 months ]
   BMD, g/cm2, adjacent to the femur implant for Gruen Zone 1-7, 3, 6, and 24 months after surgery
2. Standardised Uptake value [ Time Frame: 6 months ]
   fluoride isotope uptake, measured as (SUV), adjacent to the femoral stem, 3 and 6 months after surgery.
3. Standardised Uptake value [ Time Frame: 6 months ]
   fluoride isotope uptake, measured as SUV adjacent to the acetabular cup 3 and 6 months after surgery
4. Bone Mineral density [ Time Frame: 24 months ]
   BMD adjacent to the acetabular cup during the follow up period, i.e. after 3, 6, 12 and 24 months
5. Bone Mineral Density [ Time Frame: 24 months ]
   BMD at the lumbar spine and at the contra lateral nonoperated hip 6, 12 and 24 months after surgery
6. Standardised Uptake Value [ Time Frame: 6 months ]
   Fluoride isotope uptake measured as SUV at the lumbar spine and at the contra lateral nonoperated hip after 3 and 6 months
7. Biochemical markers for bone metabolism [ Time Frame: 24 months ]
   biochemical markers for bone turnover and the relation to SUV and BMD findings at the proximal femur and acetabulum during the follow up period, i.e. 3, 6, 12 and 24 months after surgery
8. Biochemical markers for bone metabolism in relation to Bone Mineral Density and Standardised Uptake Value [ Time Frame: 24 ]
   biochemical markers for bone turnover and the relation to SUV and BMD findings at anatomical sites not exposed to surgery, i.e. the lumbar spine and the contra lateral hip 3 and 6 months after surgery
9. Biochemical markers for bone metabolism in relation to Bone Mineral Density and Standardised Uptake Value [ Time Frame: 24 ]
   to evaluate the natural course of an uncemented THA on BMD, i.e. the placebo group 3, 6, 12 and 24 months after surgery, SUV i.e. the placebo group 3 and 6 months after surgery and on biochemical markers, i.e. the placebo group 3, 6, 12 and 24 months after surgery
10. Clinical outcome evaluation [ Time Frame: 24 months ]
    to evaluate the patients Quality of Life, measured by Harris Hip score and EQ-5D questionnaires
11. Adverse events [ Time Frame: 24 months ]
    incidence and severity of adverse events (AEs) during the study period
