TMC278-TiDP6-C136: Effect of TMC278 on Ethinylestradiol and Norethindrone in Healthy Women.
A Phase 1 study testing TMC278 in people with HIV and AIDS, run by Tibotec Pharmaceuticals, Ireland.
Trial summary
The purpose of this study is to investigate the pharmacokinetic interaction between the combination of ethinylestradiol and norethindrone and TMC278 25 mg once daily. Pharmacokinetics means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body. Read more about this study

About this study
Official title: A Phase I, Open-label Drug-drug Interaction Trial to Investigate the Effect of TMC278 25 mg q.d. on the Steady State Pharmacokinetics of Ethinylestradiol and Norethindrone, in Healthy Women
The purpose of this study is to investigate the pharmacokinetic interaction between the combination of ethinylestradiol and norethindrone and TMC278 25 mg once daily. Pharmacokinetics means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body. Furthermore the short-term safety and tolerability (how well the body tolerates the drug) of co-administration of TMC278 and ethinylestradiol and norethindrone, in healthy women, will be assessed.
Read the detailed description
Human immunodeficiency virus (HIV)-infected patients are routinely being treated with combinations of 3 or 4 drugs (highly active antiretroviral therapy [HAART]), to reduce the risk of viral resistance development. Development of new potent antiretroviral (ARV) drugs is urgently needed to prolong suppression of viral replication in patients infected with HIV. This is a Phase I, open-label trial in healthy women to investigate the pharmacokinetic interaction between the combination of ethinylestradiol and norethindrone and TMC278 25 mg once daily. The trial aims to allow further recommendations regarding the concurrent use of oral contraceptives and TMC278. The trial population will consist of 18 healthy women who are stable on oral contraceptives (OC), specifically ethinylestradiol and norethindrone, or who, if they are not currently using this OC, are willing to start or switch to this OC for the duration of the study.
Healthy volunteers will receive the OC once daily for 21 days for at least 1 OC cycle prior to Day 1 [stabilizing OC cycle from Day -28 to Day -1]. During the second OC cycle [from Day 1 to Day 28], subjects will receive the OC alone once daily for 21 days [Treatment A]. During the third OC cycle [from Day 29 to 56], subjects will receive the OC once daily for 21 days and in addition TMC278 25 mg q.d. in the morning for 15 days, starting on the first day of OC intake (Day 29) [Treatment B]. Full 24-hour pharmacokinetic profiles of ethinylestradiol and norethindrone will be determined after the first 2 weeks of the second OC cycle (Treatment A: OC alone; Day 15) and after the first 2 weeks of the third OC cycle (Treatment B: OC+TMC278; Day 43). A full 24-hour pharmacokinetic profile of TMC278 will be determined on Day 43. Blood samples on these days will be drawn just before drug intake (predose), and at 0.5, 1, 1.5, 2, 3, 4, 5 (Day 43 only), 6, 9, 12, 16 (Day 43 only) and 24 hours postdose. Safety evaluations include evaluation of adverse events, physical examination including vital signs, ECGs and laboratory hematology and biochemistry assessments. Healthy volunteers will receive a tablet of ethinylestradiol and norethindrone OC once daily for 21 days for at least 1 OC cycle prior to Day 1. During the second OC cycle, healthy volunteers will receive a tablet of ethinylestradiol and norethindrone OC alone once daily for 21 days. During the third OC cycle, healthy volunteers will receive a tablet of ethinylestradiol and norethindrone once daily for 21 days and in addition a tablet of TMC278 25 mg once daily in the morning for 15 days.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing TMC278 in people with HIV and AIDS, run by Tibotec Pharmaceuticals, Ireland.
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 5 inclusion and 12 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 28 Apr 2010. Status can change between updates, so confirm with the study contact before making plans.
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?
The primary objective of this study is to determine the effect of steady-state concentrations of TMC278 25 mg once daily on the steady-state pharmacokinetics of ethinylestradiol 35 mcg and norethindrone 1 mg once daily.. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00739622, which also lists 1 linked publication.
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 28 Apr 2010; AzTrials last refreshed its copy on 8 Nov 2026.
