The primary objective of this trial is to show that PTH(1-84) is superior to alendronate in reducing back pain intensity over a 24-week treatment period in postmenopausal women with an osteoporosis related vertebral fracture(s).

Secondly the objectives are to investigate any differences in patient reported outcomes between the two treatment arms over a 24-week treatment period in postmenopausal women with an osteoporosis related vertebral fracture(s).

Condition Intervention Phase
Back Pain
Drug: Parathyroid hormone (PTH) (1-84)
Drug: Alendronate
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A 24-week, International, Multi Centre, Randomised, Double-blind, Double-dummy, Parallel Group, Phase IV Clinical Trial Investigating Changes in Back Pain in Postmenopausal Women With an Osteoporosis Related Vertebral Fracture(s) Treated With Either 100 µg PTH(1-84) Daily or 70 mg Alendronate Weekly

Primary Outcome Measures:
  • Change in Back Pain Intensity During 24 Weeks of Treatment Using a Numerical Rating Scale. [ Time Frame: Baseline and 24 weeks treatment ]
    The daily patient assessment of intensity of back pain is based on the Numerical Rating Scale (NRS) which is an 11-point numerical rating scale (from 0-10 with 0 = "no pain" and 10 = "unendurable pain").

Secondary Outcome Measures:
  • Change in Physical Disability and Patient Reported Outcomes During 24 Weeks of Treatment [ Time Frame: Baseline and 24 weeks treatment ]

    Three times during the trial the patients will be asked how their pain affects their ability to manage everyday life. This information will be collected by use of the Oswestry Disability Index (ODI) questionnaire. The questions relate to daily life activities and indicate to what extent a person's functional level is restricted by pain.

    ODI scores from 0 = "no disability" to 100 = "maximum disability".

    Patient reported outcomes will be assessed by using two questionnaires related to health status and quality of life status.
