About this study

Official title: A Pilot Study of the Effects of High-Dose Oral Calcitriol and Physical Activity on Bone Health in Breast Cancer Survivors

Both the calcitriol and exercise interventions are aimed at reducing fracture risk by maintaining proper bone density, thereby preventing osteoporotic/osteopenic conditions and increasing muscle mass. Both calcitriol and exercise are efficacious in maintaining proper bone health and muscle mass among the general population, but little research has been done on breast cancer patients and survivors. The combination of calcitriol and exercise, which function through different but similar mechanisms, could produce interactive effects in reducing fracture risk among breast cancer survivors.

Hypothesis: A combination of calcitriol along with a structured home-based walking and progressive resistance exercise program will be efficacious in preventing bone resorption and in increasing bone formation among survivors of invasive breast cancer.

What is being measured

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

  1. Bone Resorption (Exercise)

    Bone Resorption using Serum NTx (Exercise comparison)

    Serum NTx level is used to aid in predicting skeletal response (bone mineral density) to antiresorptive therapy and in monitoring bone resorption changes following initiation of antiresorptive therapy. Elevated levels of serum NTx indicate elevated bone resorption. Elevated bone resorption is the primary cause of agerelated bone loss and that low bone mass often results in osteopenia and is the major cause of osteoporosis. The measurement range is in nanoMoles (NM) Bone Collagen Equivalents (BCE).

    Measured: Week 12

  2. Bone Resorption (Calcitriol)

    Bone Resorption using Serum NTx (Calcitriol comparison)

    Serum NTx level is used to aid in predicting skeletal response (bone mineral density) to antiresorptive therapy and in monitoring bone resorption changes following initiation of antiresorptive therapy. Elevated levels of serum NTx indicate elevated bone resorption. Elevated bone resorption is the primary cause of agerelated bone loss and that low bone mass often results in osteopenia and is the major cause of osteoporosis. The measurement range is in nanoMoles (nm) Bone Collagen Equivalents (BCE).

    Measured: Week 12

  3. Bone Formation (Exercise)

    Bone Formation using Serum BSAP (Exercise comparison)

    The Bone-Specific Alkaline Phosphatase (BSAP) assay provides a general index of bone formation and a specific index of total osteoblast activity. BSAP and osteocalcin are the most effective markers of bone formation and are particularly useful for monitoring bone formation therapies and antiresorptive therapies.

    Measured: Week 12

  4. Bone Formation (Calcitriol)

    Bone Formation using Serum BSAP (Calcitriol comparison)

    The Bone-Specific Alkaline Phosphatase (BSAP) assay provides a general index of bone formation and a specific index of total osteoblast activity. BSAP and osteocalcin are the most effective markers of bone formation and are particularly useful for monitoring bone formation therapies and antiresorptive therapies.

    Measured: Week 12

Secondary outcomes (4)
  1. Handgrip (kg) Strength - (Exercise)

    Handgrip (kg) Strength (Exercise comparison)

    Hand grip strength can be quantified by measuring the amount of static force that the hand can squeeze around a dynamometer. It is typically measured in kilograms or pounds and varies by sex and age. Normative data for females is AGE 35-39 --> 20.3-34.1kg; AGE 40-44 --> 18.9-32.7kg; AGE 45-49 --> 18.6-32.4kg; AGE 50-54 --> 18.1-31.9kg; AGE 55-59 --> 17.7-31.5kg; AGE 60-64 --> 17.2-31.0kg; AGE 65-69 --> 15.4-27.2kg; AGE 70-99 --> 14.7-24.5kg. Values less than the normal range are considered weak strength. Values greater than the normal range are considered strong strength.

    Measured: Week 12

  2. Handgrip (kg) Strength - (Calcitriol)

    Handgrip (kg) Strength - (Calcitriol comparison)

    Hand grip strength can be quantified by measuring the amount of static force that the hand can squeeze around a dynamometer. It is typically measured in kilograms or pounds and varies by sex and age. Normative data for females is AGE 35-39 --> 20.3-34.1kg; AGE 40-44 --> 18.9-32.7kg; AGE 45-49 --> 18.6-32.4kg; AGE 50-54 --> 18.1-31.9kg; AGE 55-59 --> 17.7-31.5kg; AGE 60-64 --> 17.2-31.0kg; AGE 65-69 --> 15.4-27.2kg; AGE 70-99 --> 14.7-24.5kg. Values less than the normal range are considered weak strength. Values greater than the normal range are considered strong strength.

    Measured: Week 12

  3. Body Mass Index (Exercise)

    Body Mass Index (BMI) - (Exercise Comparison)

    Measure Description: Body Mass Index (BMI) is a person's weight in kilograms divided by the square of height in meters. Values below 18.5 represent "Underweight", 18.5 to 24.9 represent "Normal or Healthy Weight", 25.0 to 29.9 represent "Overweight" and 30.0 and above represent "Obese".

    Measured: Week 12

  4. Body Mass Index (Calcitriol)

    Body Mass Index(BMI) - (Calcitriol comparison)

    Measure Description: Body Mass Index (BMI) is a person's weight in kilograms divided by the square of height in meters. Values below 18.5 represent "Underweight", 18.5 to 24.9 represent "Normal or Healthy Weight", 25.0 to 29.9 represent "Overweight" and 30.0 and above represent "Obese".

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Calcitriol, Exercise and Multivitamin in people with Breast Neoplasms and Bone and Bones, run by University of Rochester 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 15 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 23 Apr 2019. 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 Apr 2019). 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?

Bone Resorption (Exercise) (time frame: Week 12). The study lists 4 primary outcomes in all. 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 23 Apr 2019.
