About this study

Birth control pills are the most commonly used method of birth control. The purpose of this research study is to examine whether birth control pills change heart disease risk and how the body handles blood sugar when given to different women.

Read the detailed description

The oral contraceptive pill is the most commonly used birth control method. It is debated whether the birth control pill affects how the body handles insulin and sugar, or whether the pill changes heart disease risk. The goal of this study is to evaluate whether certain factors, such as how the body processes hormones, and demographic factors (e.g. body weight and race), influence how the pill affects the handling of insulin and sugar, and heart health.

What participants receive

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

  • Ortho Cyclen®Drug

    Also called Orthocyclen, Sprintec, Previfem, MonoNessa

    Ethinyl estradiol 35 mcg and norgestimate 0.25 mg (oral) will be taken as one tablet daily for 21 days per month followed by a 7-day pill-free period per cycle. Duration of the study is for 6 cycles of this birth control pill.

What is being measured

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

  1. Change From Baseline in Insulin Sensitivity

    Insulin sensitivity from Frequently sampled IV glucose tolerance test (FSIVGTT), change from baseline to 6 months. Higher values indicate better insulin sensitivity

    Measured: Baseline, 6 months

  2. Change From Baseline in Flow-mediated Vasodilatation

    Change Flow-mediated Vasodilatation from baseline to 6 months. Higher values indicate less cardiovascular risk

    Measured: Baseline, 6 months

  3. Change From Baseline in Carotid Intima Media Thickness

    Change in Carotid Intima Media Thickness from baseline to 6 months, measured on the right carotid artery, posterior. Lower values indicate better cardiovascular risk profile

    Measured: baseline, 6 months

Secondary outcomes (13)
  1. Change From Baseline in Acute Insulin Response to Glucose

    Acute Insulin Response to Glucose values obtained from FSIVGTT models--higher values indicate better insulin response

    Measured: Baseline, 6 months

  2. Change From Baseline in Glucose Effectiveness

    Obtained from FSIVGTT models--higher values indicate better effectiveness of glucose inducing its own disposition

    Measured: Baseline, 6 months

  3. Change From Baseline in Disposition Index at 6 Months

    Modeled from FISVGTT--higher values indicate better glucose disposition

    Measured: Baseline, 6 months

  4. Change From Baseline in Fasting Insulin at 6 Months

    Higher fasting insulin values indicate an increased metabolic risk

    Measured: Baseline, 6 months

  5. Change From Baseline in Fasting Glucose at 6 Months

    Higher fasting glucose indicate an increased metabolic risk

    Measured: Baseline, 6 months

  6. Change From Baseline in Areas-under-the-curve for Insulin at 6 Months

    Measured during oral glucose tolerance test. Higher values indicate increased metabolic risk

    Measured: Baselines, 6 months

  7. Change From Baseline in Areas-under-the-curve for Glucose

    Measured during oral glucose tolerance test. Higher values indicate increased metabolic risk

    Measured: Baseline, 6 months

  8. Change From Baseline in Systolic Blood Pressure at 6 Months

    Higher value indicates increased cardiovascular risk

    Measured: Baseline, 6 months

  9. Change From Baseline in HDL at 6 Months

    Lower values indicate increased cardiovascular risk

    Measured: Baseline, 6 months

  10. Change From Baseline in Body Mass Index in 6 Months

    Higher values indicate higher metabolic risk

    Measured: Baseline, 6 months

  11. Change in Diastolic Blood Pressure From Baseline to 6 Months

    Higher value indicates higher cardiovascular risk

    Measured: Baseline, 6 months

  12. Change in LDL From Baseline to 6 Months

    Higher value indicates higher cardiovascular risk

    Measured: Baseline, 6 months

  13. Change in Triglycerides From Baseline to 6 Months

    Higher values indicate higher cardiovascular risk

    Measured: Baseline, 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ortho Cyclen® in people with Insulin Sensitivity and Cardiovascular Risk, run by Virginia Commonwealth University 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 3 inclusion and 4 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 8 Aug 2018. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 10 Jul 2018). 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?

Change From Baseline in Insulin Sensitivity (time frame: Baseline, 6 months). The study lists 3 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 8 Aug 2018.
