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 50 years
- All sexes
- Healthy volunteers accepted
- 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, vital signs, laboratory tests, and ECGs. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
- Male or female between 18 and 50 years of age inclusive, at the time of signing the informed consent.
- 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 post-menopausal 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 > 40 MlU/ml is confirmatory.
- Male subjects must agree to use one of the contraception methods listed in Section 8.1 of the study protocol. This criterion must be followed from the time of the first dose of study medication until the follow-up visit.
- Body weight greater than or equal to 50 kg for men and greater than or equal to 45 kg for women and body mass index (BMI) within the range 18.5-31.0 kg/m2 (inclusive).
- Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
Who cannot join
- As a result of the medical interview, physical examination, or screening investigations, the Investigator considers the subject unfit for the study.
- The subject has a positive pre-study drug/alcohol screen. A minimum list of drugs that will be screened for include amphetamines, barbiturates, cocaine, opiates, cannabinoids and benzodiazepines.
- Unwilling to refrain from the use of illicit drugs and adhere to other protocol-stated restrictions while participating in the study.
- History of regular alcohol consumption within 6 months of the study defined as: An average weekly intake of >14 drinks/week for men or >7 drinks/week for women. Note: One drink is equivalent to (12 g alcohol) = 5 ounces (150 ml) of wine or 12 ounces (360 ml) of beer or 1.5 ounces (45 ml) of 80 proof distilled spirits.

- History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation. In addition, if heparin is used during PK sampling, subjects with a history of sensitivity to heparin or heparin-induced thrombocytopenia should not be enrolled.

In this study, approximately 16 subjects will receive raltegravir 400mg twice daily for 5 days (Treatment A) followed by a washout period. In Period 2, subjects will receive GSK2248761 200mg once daily for 5 days (Treatment B). There will be no wash out between Period 2 and 3. Subjects will then be administered raltegravir 400mg twice daily in combination with GSK2248761 200mg once daily (Treatment C) for 5 days. Subjects will be housed in the unit for the duration of the study. 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.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Raltegravir, GSK2248761 and GSK2248761 + Raltegravir in people with Infection, Human Immunodeficiency Virus, 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 25 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 11 Sep 2017. 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 raltegravir steady-state CL/F, AUC(0-tau), Cmax, tmax, Ctau, and Cmin following administration of raltegravir 400mg q12h for 5 days and following co-administration with GSK2248761 200mg q24h for 5 days. (time frame: 5 days). 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?
On the ClinicalTrials.gov record for NCT01101893, 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 11 Sep 2017.
