2.Is the subject at least 50 years of age?
3.Has the subject been postmenopausal for more than 3 years – in the judgement of the investigator?
4.Does the subject have a T-score = -1.5 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 or femoral neck (existing DXA scans up to 3 months old at the time of screening visit are accepted)
5.Does the subject have an X-ray verified vertebral fracture (reduction > 25% in anterior, middle or posterior height compared to adjacent vertebra) defined by Genant semi quantitative visual grading? (existing X-rays up to 6 weeks old at the time of screening visit are accepted)
6.Does the subject have chronic back pain which is considered to be related to one or more vertebral fractures (chronic pain is defined as 3 months with back pain likely to be caused by the vertebral fracture(s))?
7.At the screening visit: does the subject assess the intensity of her back pain this morning before any use of analgesic medication to be 4 or more on the 11 point NRS.
8.At the randomisation visit: is the average of the last 7 days back pain assessments 4 or more on the 11 points NRS (captured in the i-diary system)?
9.Is the subject willing to fill in the subject diary system (using a toll-free number)every day for the whole trial period, and register the intensity of her back pain and number of falls ?
10.Is (current) dosage and type of analgesic treatment of the subject considered to be stable and expected by the investigator to remain so within the next 6 months?
11.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 or other drug related side effects?
12.Has the subject been taking supplemental calcium (1,000 mg) and vitamin D3 (800 IU) daily for at least 14 days (after the screening visit) before blood sampling for eligibility evaluation?
13.Is the subject able to self-inject PTH(1-84), or have the injections with assistance from a helper?

7.for cancer (other than basocellular skin cancer) within the last 5 years?
8.with radiation therapy to the skeleton ever?
or has the subject ever been diagnosed with:
9.any malignant disease affecting the skeleton?
10.spondylolisthesis, intervertebral disc herniation, spinal stenosis or another spinal disease that can cause the back pain?
11.any clinically significant diseases affecting calcium metabolism?
12.any metabolic bone diseases other than primary osteoporosis (including hyperparathyroidism, Paget’s disease, osteogenesis imperfecta, or osteomalacia)?
13.fibromyalgia
14.upper gastro-intestinal problems such as dysphagia, gastritis, duodenitis, ulcers or a recent history (within the last year) of major gastrointestinal disease such as peptic ulcer, or active gastro-intestinal bleeding, or had surgery of the upper gastro-intestinal tract other than pyloroplasty?

16.or has a known history of hypersensitivity to parathyroid hormone or alendronate or any of the excipients in the IMP or dispensed supplements?
or is the subject:
17.currently receiving or intending to start (within the trial period) any non-pharmacological treatment i.e. physical and/or psychological therapies that can modulate the perception of pain? –according to the investigator’s opinion.
