About this study

Official title: A Phase-I, Open-label Trial in Healthy Female Subjects to Investigate the Effect of TMC435 at Steady-state on the Steady-state Pharmacokinetics of Ethinylestradiol and Norethindrone

The purpose of this study is to investigate the effect of steady-state concentrations of TMC435 (administered once a day) on the steady-state pharmacokinetics of ethinylestradiol and norethindrone (administered once a day) and on the levels of progesterone, luteinizing hormone and follicle-stimulating hormone, in healthy female participants. Ethinlyestradiol and norethindrone are synthetic hormones, which constitute the oral contraceptive Ovysmen. Also the short-term safety and tolerability of the co-administration of TMC435 and Ovysmen will be studied. Steady-state is a term that means that the drug has been given long enough so that the plasma concentrations will remain the same with each subsequent dose. TMC435 is being investigated for the treatment of chronic hepatitis C virus (HCV) infection. Pharmacokinetics (PK) means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body. A contraceptive is a method that prevents pregnancy.

Read the detailed description

This is a Phase I, open-label (both participant and investigator know the name of the medication given at a certain moment) trial in 18 healthy female participants to investigate the effect of TMC435 at steady-state on the steady-state pharmacokinetics of ethinlyestradiol and norethindrone. Ethinylestradiol (35 µg) and norethindrone (1.0 mg) are the components of Ovysmen, which is a widely used oral contraceptive (OC). All subjects will receive OC therapy for 2 complete OC cycles. During the first cycle, participants will receive Ovysmen alone, once daily, for the first 21 days. An OC- free period is respected from Day22 till and including Day28. During the second OC cycle, participants will receive again Ovysmen once daily during the first 21 days plus TMC435 150 mg once daily as of Day12 till and including Day21. Next, a OC-free period from Day22 till and including Day28 is established. Full 24-hour PK profiles of ethinylestradiol and norethindrone will be determined at the last day of OC treatment of the first OC cycle (i.e. on Day21) and on the last day of OC treatment of the second OC cycle (i.e. Day21). Full 24-hour PK profile of TMC435 will be determined on Day21 of second OC cycle. Pharmacodynamic (how the body reacts on the drug) assessments of serum levels of progesterone, luteinizing hormone and follicle-stimulating hormone (these hormones are involved in ovulation and in preparation of the womb for a pregnancy) will be done on Day1, 19, 20 and 21 of both OC cycles. Safety and tolerability will be assessed during the study period and during follow up. Blood and urine safety samples, electrocardiogram (ECG) and vital signs (blood pressure and heart rate) will be taken at screening, Day1, Day21 and Day22 of each OC cycle, and at the follow-up visit about 5 to 7 days after last TMC435 intake. A physical examination will be performed at screening, Day1 and Day20 of each OC cycle, and at the follow-up visit about 5 to 7 days after last TMC435 intake. Participants are admitted to the unit on Day20 in the morning and are discharged on Day22, for both OC cycles.

What is being measured

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

  1. Change in the steady-state plasma PK of ethinylestradiol following co-administration with TMC435

    PK characteristics of ethinylestradiol and norethindrone are determined based on their respective plasma levels at one time point (Day19, 20 and 22) and at 10 time points (Day22). Standard PK parameters such as C0h, Cmin, Cmax, Tmax, AUC24h etc. will be determined.

    Measured: Measured on Day19 till and including Day22 of 2nd OC cycle. Reference is Day19 till and including Day22 of 1st OC cycle.

  2. Change in the steady-state plasma PK of norethindrone following co-administration with TMC435

    PK characteristics of ethinylestradiol and norethindrone are determined based on their respective plasma levels at one time point (Day19, 20 and 22) and at 10 time points (Day22). Standard PK parameters such as C0h, Cmin, Cmax, Tmax, AUC24h etc. will be determined.

    Measured: Measured on Day19 till and including Day22 of 2nd OC cycle. Reference is Day19 till and including Day22 of 1st OC cycle.

Secondary outcomes (4)
  1. Change in the plasma levels of progesterone following co-administration of Ovysmen and TMC435.

    Plasma levels of progesterone.

    Measured: Measured on Day1, 19, 20 and 21 of 2nd OC cycle. Reference is Day1, 19, 20 and 21 of 1st OC cycle.

  2. Number of participants (%) with adverse events as a measure of safety and tolerability when combining TMC435 (150 mg, q.d.) with Ovysmen (35 µg ethinylestradiol + 1 mg norethindrone, q.d.)

    Measured: Day of Screening + 21 days between screening and Day1 of first OC cycle + 28 days of first OC cycle + 28 days of second OC cycle

  3. Change in the plasma levels of luteinizing hormone following co-administration of Ovysmen and TMC435.

    Plasma levels of luteinizing hormone.

    Measured: Measured on Day1, 19, 20 and 21 of 2nd OC cycle. Reference is Day1, 19, 20 and 21 of 1st OC cycle.

  4. Change in the plasma levels of follicle-stimulating hormone following co-administration of Ovysmen and TMC435.

    Plasma levels of follicle-stimulating hormone.

    Measured: Measured on Day1, 19, 20 and 21 of 2nd OC cycle. Reference is Day1, 19, 20 and 21 of 1st OC cycle.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing TMC435 and Ovysmen in people with Hepatitis C Virus, run by Tibotec Pharmaceuticals, Ireland at 1 site in Belgium.

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 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 31 Jan 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 Belgium. 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?

Change in the steady-state plasma PK of ethinylestradiol following co-administration with TMC435 (time frame: Measured on Day19 till and including Day22 of 2nd OC cycle. Reference is Day19 till and including Day22 of 1st OC cycle.). The study lists 2 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 31 Jan 2013.
