Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 45 years and older
  • Women only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • They were pathologically diagnosed with DTC including papillary or follicular carcinoma. (2) They received a near total thyroidectomy and radioiodine treatment. (3) TSH suppression should be at least one year before the study. (4) Bone mineral density (BMD) in lumbar spine and/or hip was tested by Dual-energy X-ray absorptiometry (DXA) at baseline, 6 month (m) and/or 12m follow up. 5) The diagnosis of osteoporosis was T-score ≤-2.5 SD at the lumbar spine, or hip.

Who cannot join

  • patients having medications for osteoporosis before TSH suppression treatment;
  • secondary osteoporosis ;
  • severe liver or kidney disease;
  • myelosuppression;
  • digestive disease;
  • long term use of immunosuppressive agent, estrogen or estrogen receptor modulators. This study was approved by the Institutional Review Board of Hospital Research Ethics. All the patients were fully acquainted with their treatment and consented to participate in the clinical trial.

About this study

Official title: Prospective Trial of 99Tc-MDP and Fosamax in Postmenopausal Women With Differentiated Thyroid Cancer and Osteoporosis Treated With Supraphysiological Doses of Thyroid Hormone

Postmenopausal women with differentiated thyroid cancer (DTC) taking suppressive doses of levothyroxine (L-T4) are thought to have accelerated bone loss and increased risk of osteoporosis. Therefore, the investigators try to investigate the effects of 99Tc-MDP,alendronate sodium in postmenopausal women with DTC under TSH suppression and osteoporosis.

Read the detailed description

Differentiated thyroid cancer (DTC) has become one of the most common endocrine malignancies. According to American Thyroid Association (ATA) and Chinese Thyroid Association (CTA), most of DTC patients undergo total or near total thyroidectomy, radioiodine ablation and TSH (thyroid stimulating hormone) suppression. Osteoporosis (OS) and fractures are important comorbidities in patients with DTC, with potential negative impact on quality of life (QOL) and survival. The main determinant of skeletal fragility in DTC is the TSH suppression. Postmenopausal women with DTC under TSH suppression therapy are more vulnerable to OS. Technetium-99 methylene diphosphonate (99Tc-MDP) is a decay product of 99mTc-MDP (used for bone scintigraphy) and a novel bisphosphonates, which has been used in China for diseases like rheumatoid arthritis (RA), ankylosing spondylitis (AS) and osteochondral lesions of the talus, etc. However, as a member of bisphosphates, little attention has been paid to its anti-OS effect for DTC under TSH suppression.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent Change of Bone Mineral Density in Lumbar and Hip

    Percent change of bone mineral density in lumbar and hip by dual energy x-ray absorptiometry

    Measured: baseline, 6 months, and 12 months

Secondary outcomes (3)
  1. Bone Turnover Markers

    bone turnover markers including C-telopeptides of type I collagen (CTX), Type I N-procollagen terminal propeptide(PINP)

    Measured: baseline and 12 months

  2. Health Related Quality of Life by 36-item Short Form Health Status Survey Questionnaire (0-100)

    The health related quality of life was measured by 36-item Short Form Health Status Survey questionnaire (SF-36). The minimum and maximum values were 0 and 100, respectively. Higher scores mean a better a better outcome.

    The questionnaire includes 36 items that can be classified into the following eight health status subscales: Physical Functioning, Physical Role Limitations, Bodily Pain, General Health Perception, Vitality, Social Functioning, Emotional Role Limitations, and Mental Health. A standardized Physical Component Summary and a standardized mental component score were calculated. The physical component summary and mental component summary represent the deviation from the reference population in Sweden. Higher scores mean a better a better outcome.

    Measured: baseline, 6 months, and 12 months

  3. Side Effects

    A transient rash and phlebitis, gastrointestinal reaction.

    Measured: 6 months, and 12 months

Questions about this trial

What is this clinical trial studying?

A study testing 99Tc-MDP and Fosamax in people with Differentiated Thyroid Cancer and Osteoporosis, run by Xinhua Hospital, Shanghai Jiao Tong University School of Medicine at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Oct 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percent Change of Bone Mineral Density in Lumbar and Hip (time frame: baseline, 6 months, and 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Nov 2021.
