NCT00479037

Brief Summary

The primary objective of this trial is to show that PTH(1-84) is superior to strontium ranelate in bone formation measured as changes in bone formation markers over a treatment period of 24 weeks in postmenopausal women with primary osteoporosis.

Outcome Measures

Primary Outcomes (2)

  • Percentage Change in the Bone Formation Marker N-terminal Propeptides of Human Procollagen Type I (P1NP) From Baseline to End of Trial

    P1NP is a bone formation marker that is derived from the amino-terminal propeptides of type I collagen and is considered a quantitative measure of newly formed type I collagen. Bone marker measurements were done by blood analysis.

    Baseline and 24 weeks of treatment

  • Percentage Change in the Bone Formation Marker Bone Specific Alkaline Phosphatase (BSAP) From Baseline to End of Trial

    BSAP is a marker of bone formation that reflects the cellular activity of osteoblasts. Bone marker measurements were done by blood analysis.

    Baseline and 24 weeks of treatment

Secondary Outcomes (1)

  • Percentage Change in the Bone Resorption Marker C-Telopeptide Cross-links (CTX) From Baseline to End of Trial

    Baseline and 24 weeks of treatment

Study Arms (2)

PTH(1-84)

ACTIVE COMPARATOR
Drug: Full Length Parathyroid Hormone, PTH(1-84)

Strontium Ranelate

ACTIVE COMPARATOR
Drug: Strontium Ranelate

Interventions

Once daily subcutaneous injection in the abdomen by self administration

Also known as: Preotact
PTH(1-84)

The daily dose of 2 g (one sachet) strontium ranelate was to be mixed in a glass of water and taken immediately after mixing at bedtime at least 2 hours before or after intake of calcium, any food or drinks, other than water

Strontium Ranelate

Eligibility Criteria

Age50 Years+
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may not qualify if:

  • Has the subject given informed consent according to local requirements before any trial related activities? (A trial related activity is any procedure that would not have been performed during the routine management of the subject).
  • Is the subject female and at or above the age of 50?
  • Has the subject been postmenopausal for more than 5 years - in the judgement of the investigator?
  • Does the subject have primary osteoporosis and a T-score equal to or lower than -2.5 SD; T-scores must be assessed by DXA at the lumbar spine L1-L4, with a minimum of two assessable vertebrae, or at the total hip (right hip, if there is a right hip prosthesis, left hip can be used. If both hips are replaced the subject can be included with a lumbar scan only).
  • Is the subject currently taking calcium and vitamin D3 or is she willing to start such supplemental treatment and continue throughout the trial period, unless she develops hypercalcaemia?
  • Has the subject been taking supplemental calcium (1,000 mg) and vitamin D3 (800 IU) daily for at least 14 days (after screening) before blood sampling for eligibility evaluation? \[\*\]
  • Is the subject able to self-inject PTH(1-84), or get the injections by a helper?
  • Has the subject:
  • been treated with SERMS (selective oestrogen receptor modulators) or calcitonin within the last 1 month?
  • ever been treated with any bisphosphonate in intravenous form (i.v.)?
  • been treated with any bisphosphonates (alendronate, risedronate, or other bisphosphonates) for more than 3 years in total, or within the last 6 months?
  • been treated with fluoride for more than 3 months within the last 10 years?
  • ever been treated with strontium ranelate?
  • ever been treated with teriparatide or PTH(1-84)?
  • received or is the subject currently receiving chronic glucocorticosteroid treatment?
  • +20 more criteria

Limitations and Caveats

A limitation of the trial was the open label design, however this is not considered to affect the primary or secondary outcome of the trial.
