Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 65 years
- All sexes
- Healthy volunteers accepted
- Adult, Older adult
Who may be able to join
- Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring.
- Male or female between 18 and 65 years of age, inclusive.
- A female subject is eligible to participate if she is of non-childbearing potential (i.e., physiologically incapable of becoming pregnant) including any female who: Is pre-menopausal with a documented bilateral tubal ligation, bilateral oophorectomy (removal of the ovaries) or hysterectomy, or Is postmenopausal defined as 12 months of spontaneous amenorrhea. A follicle stimulating hormone (FSH) level will be performed to confirm a post-menopausal status. For this study, FSH levels of > 40 MlU/ml is confirmatory. For females on hormone replacement therapy (HRT) and whose menopausal status is in doubt, HRT should be discontinued for 2 weeks and then the subject rescreened, as HRT can suppress FSH.
- Male subjects must agree to use one of the contraception methods listed in the protocol. This criterion must be followed from the time of the first dose of study medication until 14 days after the last dose of study medication.

About this study
Official title: A Phase I, Open Label, Randomized, Three Period, One-way, Two Cohort, Adaptive Crossover Study to Evaluate the Effect of Darunavir/Ritonavir Plus Etravirine and Lopinavir/Ritonavir Plus Etravirine on GSK1349572 Pharmacokinetics in Healthy Adult Subjects (ING112934)
A Phase I, open label, randomized, three period, one-way, two cohort, adaptive crossover study to evaluate the effect of darunavir/ritonavir plus etravirine and lopinavir/ritonavir plus etravirine on GSK1349572 pharmacokinetics in healthy adult subjects
Read the detailed description
The study is a three period, randomized, open label study. Approximately 18 healthy subjects will receive GSK1349572 50mg q24h for 5 days (Treatment A) in Period 1. Subjects will then be administered GSK1349572 50mg q24h in combination with either LPV/RTV 400/100 mg q12h and etravirine 200mg q12h (Treatment B, n=9) or DRV/RTV 600/100 mg q12h and etravirine 200mg q12h (Treatment C, n=9) for 14 days in Period 2 followed by a washout period. GSK1349572 PK data will be obtained from Periods 1 and 2 and used to inform decision making on Period 3. If GSK1349572 Cτ is reduced by more than 50% in Period 2 compared to Period 1, subjects will return to the clinic and receive GSK1349572 50mg q12h in combination with ETV and either DRV/RTV or LPV/RTV in Period 3. Safety evaluations and serial PK samples will be collected during each treatment period. A follow-up visit will occur 7-14 days after the last dose of study drug. All doses of study drugs will be taken following a moderate fat meal.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Darunavir, Etravirine and Ritonavir in people with Healthy Volunteer, run by ViiV Healthcare 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 7 inclusion and 21 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 22 Feb 2012. 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 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 GSK1349572 steady-state AUC(0-τ), Cmax, C0, Cτ, and Cmin following administration of GSK1349572 50mg and following co-administration of GSK1349572 50mg with ETV/LPV/RTV 200/400/100mg or ETV/DRV/RTV 200/600/100mg (time frame: 14 days). 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 22 Feb 2012.
