About this study

Official title: An Open-label Study to Evaluate the Pharmacokinetics of an Oral Contraceptive Containing Levonorgestrel and Ethinyl Estradiol When Co-administered With GSK1265744 in Healthy Adult Female Subjects

This open-label, fixed-sequence crossover study aims to evaluate the effect of GSK1265744 (744) oral administration on the pharmacokinetics (PK) and pharmacodynamics (PD) of a commonly used oral contraceptive (OC) product (combination of ethinyl estradiol and levonorgestrel), in 20 healthy female subjects. Each subject will participate in a Run-in Period (if needed), followed by a single-sequence Treatment Period. Subjects will receive oral contraceptive containing Levonorgestrel and Ethinyl Estradiol on Days 1 to 21 and be OC free on Days 22 to 28, during which withdrawal menses should occur. Subjects will receive OC alone on Days 1 to 10. Levonorgestrel (LNG) and ethinyl estradiol (EE) PK will be determined on Day 10. Subjects will then co-administer 744 and OC on Days 11 to 21. Levonorgestrel and ethinyl estradiol PK will be determined again on Day 21 to assess if co-administration with 744 results in a significant change in OC exposure compared to OC alone. Subjects will return to the study center for final follow-up evaluations 7 to 14 days after the last dose of study medication (Days 28 to 35).

Study groupRoleWhat they receive
OC containing levonorgestrel and ethinyl estradiol + GSK126574ExperimentalEligible subjects will enter a run-in-period of 21 days (may extend to 49 days) to stabilize on OC containing levonorgestrel and ethinyl estradiol in order to synchronize the menstrual cycles of multiple subjects. Subjects completing run-in-period will enter Treatment period 1 and will be dosed OC once daily on Days 1 to 10. At day 11 subjects will enter Treatment period 2 and will be dosed with OC containing levonorgestrel and ethinyl estradiol + 744 once daily on Day 12 to 19. Subjects completing Treatment period 2 will have 7 OC free days (Day 22 to 28) during which withdrawal menses should occur. Subjects will then be followed up for 7 to 14 days (Day 28 to 35/49).
Receives: Drug: Ethinyl Estadiol; Drug: Levonorgestrel; Drug: GSK1265744

What is being measured

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

  1. Plasma (AUC[0-tau])

    Blood samples will be collected to estimate the area under the concentration-time curve over the dosing interval (AUC[0-tau]) of LNG and EE following OC with and without 744

    Measured: Period 1: Predose on Day 9 and on Day 10: predose, and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, and 24 hours postdose. Period 2: Predose on Day 20 and on Day 21 predose, and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, and 24 hours postdose

Secondary outcomes (7)
  1. Safety and tolerability of 744 when given with and without OC as assessed by adverse events (AE)

    Safety and tolerability as assessed by number of participants with AEs

    Measured: Up to 72 days

  2. Safety and tolerability of 744 when given with and without OC as assessed by clinical laboratory tests

    Safety laboratory parameters included hematology and clinical chemistry analysis and ECG

    Measured: Up to 72 days

  3. Safety and tolerability of 744 when given with and without OC as assessed by Electrocardiogram (ECG)

    Measured: Up to 72 days

  4. Safety and tolerability of 744 when given with and without OC as assessed by vital signs

    Vital signs will include pulse rate and blood pressure measurements

    Measured: Up to 72 days

  5. Composite of plasma pharmacokinetic (PK) parameters of 744

    Maximum observed plasma concentration (Cmax), plasma concentration at the end of the dosing interval (Ctau), time to maximum drug concentration (tmax), and oral clearance (CL/F) CL/F will be used to evaluate the pharmacokinetics of LNG and EE after OC alone and after OC with 744.

    Measured: Period 1: Predose on Day 9 and on Day 10: predose, and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, and 24 hours postdose. Period 2: Predose on Day 20 and on Day 21 predose, and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, and 24 hours postdose

  6. Predose serum levels of Progesterone, Luteinizing hormone (LH) and follicle stimulating hormone (FSH)

    To assess the impact of 744 on the pharmacodynamic effects of OC on endogenous LH, FSH, and progesterone levels when given in combination compared with these parameters when OC is administered alone

    Measured: At Screening and predose on Days 1, 10, 11, 21, and 22

  7. Composite of plasma PK parameters of 744 - AUC(0-tau), Cmax, tmax, Ctau and CL/F

    To evaluate the PK of 744 when co-administered with LNG and EE

    Measured: Predose on Day 20 and on Day 21: predose and at 1, 2, 3, 4, 6, 8, 12, and 24 hours post dose on Day 22

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ethinyl Estadiol, Levonorgestrel and GSK1265744 in people with Infections, Human Immunodeficiency Virus and Hepatitis, run by ViiV Healthcare at 1 site in United Kingdom.

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 6 inclusion and 18 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 7 Jul 2015. 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 Kingdom. 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 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?

Plasma (AUC[0-tau]) (time frame: Period 1: Predose on Day 9 and on Day 10: predose, and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, and 24 hours postdose. Period 2: Predose on Day 20 and on Day 21 predose, and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, and 24 hours postdose). 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 7 Jul 2015.
