Study summary

Osteoporotic vertebral compression fractures (OVCFs) are serious health problems. Transplantation of mesenchymal stem cells (MSCs) has gained considerable attention to treat osteoporosis and OVCFs because implanted healthy MSCs could be differentiated into osteoblasts and reduce the susceptibility of fractures by facilitating new bone formation.

This study compares teriparatide (PTH 1-34) injection to combined treatment with Wharton's jelly-derived MSCs (WJ-MSCs) and teriparatide (PTH 1-34) in patients with OVCFs.

It is a randomized, open-label, phase 2 study.

Inclusion criteria

  • women over 40 years of age
  • Compression fracture of the spine confirmed by MRI or bone scan

    • When the T score of the lumbar spine is less than -1.0 in the bone density test using DXA (Dual energy X ray absorptiometry)
    • Compression fracture is between 5th thoracic and 5th lumbar vertebra
    • When a new vertebral fracture occurs in less than 3 parts of the spine
    • Compression fracture of the spine within 6 weeks after minor trauma
  • Oswestry Disability Index (ODI) due to vertebral fracture is more than 30%
  • Back pain due to vertebral fracture has a Visual Analogue Scale (VAS) of 4 or higher.
  • In case of writing consent for stem cell transplantation therapy

Exclusion criteria

Exclusion Criteria:

  • Those who used osteoporosis treatment (bisphosphonate, selective estrogen receptor modulator, or parathyroid hormone) 6 months before the start of the clinical trial due to osteoporotic vertebral fracture.
  • In the case of inherited, metabolic, neoplastic, or infectious bone disease other than osteoporosis
  • Spinal fracture with neurological symptoms
  • Those who are taking drugs that affect bone metabolism such as .
  • Those who have undergone spinal fixation surgery on the fracture site prior to the clinical trial
  • Those who have a history of psychiatry or who are currently undergoing treatment, who have judged that it is difficult to proceed with the clinical trial under the judgment of the researcher
  • Those who do not understand the purpose and method of this clinical trial as a study subject for drug or alcohol addiction
  • Those who participated in other clinical trials within 30 days prior to participation in the clinical trial
  • Those who may affect this clinical trial due to serious medical conditions (hypertension not controlled by drugs, diabetes not controlled by drugs, blood coagulation disease, cirrhosis, kidney failure, tumor) or immune deficiency
  • Factors less than 10 g/dL of in general blood test
  • If there is currently an acute systemic or local infection
  • Others who have findings deemed inappropriate for this clinical trial due to medical judgment by the person in charge of the clinical trial
  • Those who are allergic to proteins required for cell production (fetal calf serum)
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

What researchers measure

Primary outcomes

  1. improvement in Visual Analogue Scale

    Change in the VAS at 1, 3, 6, 9, and 12 months after the transplantation of Wharton's jelly-derived MSCs (WJ-MSCs), compared to before the transplantation. on a scale of 0 to 10, with 0 meaning no pain and 10 meaning the worst pain you can imagine.

    Time frame: 12 months

Secondary outcomes

  1. improvement in Oswestry Disability Index

    Change in the ODI at 1, 3, 6, 9, and 12 months after the transplantation of WJ-MSCs, compared to before the transplantation. on a scale of 0 to 3, with 0 meaning no disability and 10 meaning severe disability

    Time frame: 12 months

  2. Change in the T score (lumbar spine and femoral neck) of dual-energy x-ray absorptiometry

    Change in the T score (lumbar spine and femoral neck) of dual-energy x-ray absorptiometry at 6 and 12 months after the transplantation compared to before the transplantation

    Time frame: 12 months

  3. Presence of new vertebral fracture

    identification of spine fracture based on x ray

    Time frame: 12 months

  4. Change in the bone mineral density (computed tomography) of fractured vertebrae

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 24, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
