Parathyroidectomy and Mobility Study
What this study is about
This study evaluates whether surgical removal of the parathyroid gland (parathyroidectomy) improves physical function and mobility in older adults with primary hyperparathyroidism (PHPT). PHPT, a common endocrine disorder in older adults, is associated with reduced muscle strength, mobility, and quality of life.
View original scientific description
This study evaluates whether surgical removal of the parathyroid gland (parathyroidectomy) improves physical function and mobility in older adults with primary hyperparathyroidism (PHPT). PHPT, a common endocrine disorder in older adults, is associated with reduced muscle strength, mobility, and quality of life. This prospective observational study will enroll up to 80 participants aged 60 and older undergoing parathyroidectomy at UF Health. Participants will complete physical performance tests, wear an Actigraph device to assess physical activity, and provide blood samples for biomarker analysis at pre- and post-operative time points. The goal is to characterize changes in physical function and activity following surgery and to identify biomarkers that may predict mobility improvements. Findings will help inform future larger-scale studies and could expand surgical indications for PHPT in older adults.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Age ≥ 60 years;
- Biochemical diagnosis of hypercalcemic (corrected serum calcium \>10.2 mg/dL or ionized serum calcium \>1.31 mmol/dL or 5.2 mg/dL on at least one serum sample) primary hyperparathyroidism as determined by board-certified endocrinologist or endocrine surgeon;
- Undergoing parathyroidectomy at UF Health;
- Willing and able to give informed consent.
Exclusion criteria
- Failure to provide informed consent;
- Biochemical diagnosis of eucalcemic primary hyperparathyroidism (corrected serum calcium ≤10.2 mg/dL or ionized serum calcium ≤1.31 mmol/dL or 5.2 mg/dL on at least one serum sample);
- Elected not to undergo parathyroidectomy at UF Health;
- Major surgery as deemed by principal investigator or hip/knee replacement in the past 6 months;
- Fractures to the hands, arms or legs within the last 6 months;
- Traumatic accident (i.e. motor vehicle collision, fall from elevation, etc.) resulting in orthopedic trauma or requiring prolonged immobilization (\>2 weeks) within the last 6 months;
- Blood transfusion within the past 3 months;
- Self-reported myocardial infarction, cerebrovascular accident, or unstable angina within the past 6 months;
- NYHA Class 3 or 4 congestive heart failure;
- Major psychiatric disorder;
- Cancer requiring treatment in the past 1 year (including metastatic cancer), except for locally treated non-melanoma skin cancers or cancers that have clearly been cured or in the opinion of the investigator carry an excellent prognosis (e.g., Stage 1 cervical cancer);
- Renal failure requiring hemodialysis or peritoneal dialysis
- Use of bone-modifying therapies (alendronate \[Fosamax\], zoledronic acid \[Reclast\], denosumab \[Prolia or Xgeva\], or romosozumab \[Evenity\]) within 1 month of planned surgery
- Planning to permanently leave the area within 3 months of parathyroidectomy;
- Vision or hearing impairment - defined as unable to read or listen/follow instructions despite the use of maximal assistive devices (i.e. contact lenses, glasses, hearing aids, etc.)
- Participating in another clinical trial or has received an investigational product within 30 days prior to screening/enrollment.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
