  • Ages 40 to 60 years
  • Women only
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Women in late menopausal transition or early menopause
  • Age 40-55
  • BMI >25 kg/m2
  • Suffer from menopausal symptoms
  • Change in previously regular cycles consisting of at least ≥2 skipped cycles and an interval of amenorrhea (≥60 days) in the last year

About this study

Specific Aim 1: To compare effects of Vitamin D supplementation to usual care on symptoms in women transitioning to early postmenopause and determine the associated effect size in order to conduct a power analysis for a future RCT. Hypothesis: Vitamin D insufficient women in early postmenopause who are randomized to supplementation, titrated to achieve sufficiency for 2 months, will have fewer symptoms including hot flashes, mood, and musculoskeletal complaints than women randomized to usual care.

Specific Aim 2: To compare effects of Vitamin D supplementation to usual care on body composition (by dual-energy x-ray absorptiometry [DXA] and by weight, BMI, waist to hip ratio) in overweight/obese women transitioning to early postmenopause and determine the associated effect size for a power analysis for a future RCT. Hypothesis: Vitamin D insufficient women in the menopausal transition randomized to supplementation, titrated to achieve sufficiency for 9 months, will improve DXA body composition (less total body and abdominal fat), compared to women in usual care, who will have increased body weight, including total and abdominal fat.

Specific Aim 3: To estimate the proportion of overweight/obese middle-aged women who achieve sufficiency by 1 month versus 2 or more months and to determine if achieving sufficiency by 1 month varies by baseline characteristics. Hypothesis: About 80% of participants will achieve sufficient Vitamin D level by 1 month. Those who need more than 1 month for sufficiency will have lower baseline levels and higher initial BMI.

Read the detailed description

It is increasingly recognized that Vitamin D deficiency affects more than just bone health. Links between Vitamin D deficiency have been established or purported for diabetes, the metabolic syndrome, cardiovascular disease, and cancer. We propose to explore if Vitamin D replacement (safe, readily available, and inexpensive) has beneficial effects on 2 novel outcomes in early postmenopausal women: menopause-related symptoms and body composition.

Most women transitioning through menopause, especially those with higher percent body fat, will experience hot flashes through a mean of 4 to 5 years. Many also have mood disturbances and muscle aches although the link with the menopausal transition is less clear. In many, these symptoms are severe enough to negatively impact their quality of life, work performance, and interpersonal relationships. Current treatments for menopause-related symptoms, such as menopausal hormone therapy, antidepressants, and anticonvulsants, have significant side effects and serious long term adverse consequences and symptoms recur after treatment discontinuation. A safe, inexpensive, well-tolerated treatment is therefore of high priority.

Both our preliminary data in early postmenopausal women and a 2010 publication of women on aromatase inhibitors for breast cancer show an association between Vitamin D deficiency and menopause-related symptoms including hot flashes. It is postulated that a contributor to hot flashes is a menopausal decline in serotonin, a neurotransmitter with known effects on thermoregulation. As Vitamin D can protect against experimental serotonin depletion in rats, one proposed mechanism for symptom alleviation is prevention of serotonin decline in menopause.

Both Vitamin D deficiency and the menopausal transition are associated with mood disturbances and musculoskeletal aches. Because estrogen increases the activity of the enzyme responsible for activating Vitamin D, the fall in estrogen that occurs during the menopausal transition could uncover previously subclinical Vitamin D deficiency. Indeed, Vitamin D can improved mood and muscle aches in non-menopausal populations, but its effects in menopausal women, where the benefits may be magnified, have not been previously studied.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Vitamin DDietary supplement

    We will administer 100,000 IU Vitamin D3 orally as an observed 1-time bolus and then prescribe 1000 IU by mouth daily. These doses have achieved sufficiency in other populations.99, 100 We will use the level of sufficiency (≥30 ng/ml [≥75 nmol/L]) that is recommended by most experts in the field.89-91, 93, 95, 96, 101-105 We will repeat the bolus at 1 month if the target level is not achieved. The control group will receive matching placebo and a similar proportion will go through a dummy titration. All women consuming less than 800 mg/day of calcium (by dietary history) will receive 500 mg of calcium to ensure sufficiency.

  • PlaceboOther

    Current standard of practice does not dictate that otherwise healthy early menopausal women have Vitamin D levels evaluated. Women with Vitamin D levels between 10 and 29 ng/ml who receive placebo will be receiving usual care (i.e., no additional Vitamin D repletion above intake at the time of screening).

What is being measured

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

  1. compare effects of Vitamin D supplementation to usual care on symptoms in women transitioning to early postmenopause and determine the associated effects

    Vitamin D levels will be measured at baseline, after dose adjustments, and at the 3 month and final visit.

    Measured: 12 months

Secondary outcomes (1)
  1. compare effects of Vitamin D supplementation to usual care on body composition (by dual-energy x-ray absorptiometry [DXA] and by weight, BMI, waist to hip ratio) in overweight/obese women transitioning to early postmenopause

    Body composition will be measured with DXA113, 114 and anthropometric techniques (weight, height, BMI, waist to hip ratio)

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Vitamin D in people with Hot Flushes and Menopause, Premature, run by Kaiser Permanente at 1 site in United States.

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 8 inclusion and 14 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 30 May 2013. 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 United States. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

compare effects of Vitamin D supplementation to usual care on symptoms in women transitioning to early postmenopause and determine the associated effects (time frame: 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 30 May 2013.
