Trial summary

Investigators plan to carry out a study to investigate two different pills, Vitamin D and melatonin, and whether they can reduce the spread of cancer cells in the tumors of women with breast cancer. These pills are inexpensive and have very few side effects. Read more about this study

About this study

Investigators plan to carry out a study to investigate two different pills, Vitamin D and melatonin, and whether they can reduce the spread of cancer cells in the tumors of women with breast cancer. These pills are inexpensive and have very few side effects. A large number of studies using cell cultures and animals have shown that both vitamin D and melatonin can help destroy breast cancer cells. However thoughtful and well-designed studies are necessary on humans to see if they can decrease the spread of breast cancer, and possibly even prevent breast cancer. The proposed study aims to understand the anti-cancer activity of vitamin D and melatonin. This knowledge will assist in creating efficient cancer prevention strategies for Canadians. This study will include women with breast cancer who are being planned for surgery, and will assess whether treatment with vitamin D (dose of 2000 IU per day) in a group of 36 women, or melatonin (dose of 20mg per day) in another group of 36 women, or both pills together in yet another group of 36 women, reduces the spread of cancer cells when compared to a fourth group of 36 women who are treated with sugar pills. To do this we will measure a substance in the blood called Ki67, which provides information about the spread of cancer. Investigators will compare the Ki67 levels in the 4 groups, and all women will receive identical appearing pills so they will not know which treatment they received.

What participants receive

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

  • MelatoninDrug

    Melatonin 20mg taken orally once daily. This is in the form of one capsule which contains two pills of melatonin, 10 mg each.

  • Vitamin DDrug

    Vitamin D 2000 IU taken orally once daily. This is in the form of one capsule which contains two pills of vitamin D, 1000 IU each.

  • Placebo (melatonin)Drug

    Overencapsulated placebo capsule which contains an inert substance. The capsule appears identical to the capsule which contains melatonin tablets.

  • Placebo (vitamin D)Drug

    Overencapsulated placebo capsule which contains an inert substance. The capsule appears identical to the capsule which contains vitamin D tablets.

What is being measured

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

  1. Ki67

    The primary outcome is the difference in proliferation rate of Ki67 in the tumour (expressed as the percentage of tumour cells expressing Ki67). Ki67 will be measured on the original core biopsy (pre-treatment) and on the lumpectomy/mastectomy specimen (post-treatment).

    Measured: From time of initial biopsy to the final surgery, which is on average 4 weeks

Secondary outcomes (1)
  1. microRNA

    Change in serum profile of microRNA at the time of surgery (lumpectomy or mastectomy, post-treatment) will be compared to the time of initial biopsy (pre-treatment).

    Measured: At the time of surgery compared to time of biopsy, which is on average 4 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Melatonin and Vitamin D in people with Early Stage Breast Cancer, run by Juravinski Cancer Center at 2 sites in Canada.

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 2 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 16 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Canada. 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 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?

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?

Ki67 (time frame: From time of initial biopsy to the final surgery, which is on average 4 weeks). 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 16 Jun 2017.
