About this study
Official title: A Double Blind, Placebo Controlled, Single and Repeat Dose Escalation Study of GSK2838232 With and Without Ritonavir for 8-11 Days in Healthy Subjects
The proposed study, 200207 is a double blind, placebo controlled, single and repeat dose escalation study to investigate the safety, tolerability and PK of GSK2838232 alone and when co-administered with RTV 100 milligram (mg) Once daily (QD). This study will enable future clinical development of GSK2838232 in healthy subjects and in a Phase IIa proof of concept study in Human Immunodeficiency Virus (HIV) infected patients. This study is a single and repeat dose escalation study and will be conducted as two Parts. Part A will evaluate GSK2838232 20 mg and 50 mg administered QD for 8 days and Part B will evaluate GSK2838232 10 mg, 20 mg, and 50 mg, co-administered with RTV 100 mg, QD for 11 days. The extended period of dosing is to account for the longer terminal phase half-life of GSK2838232 when given with RTV. Dose cohorts will be enrolled sequentially; enrollment into a cohort will commence following review of interim PK and safety data from at least 4 subjects in the preceding cohort. Subjects in both parts will have a screening visit within 30 days prior to first dose and a follow-up visit 7-14 days after the last dose. Maximum duration of study participation will be approximately 7 weeks. Approximately 40 healthy subjects will be enrolled, 8 subjects/cohort. Subjects will be randomized 3:1 to receive GSK2838232 or placebo.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing GSK2838232 and Ritonavir in people with Infection, Human Immunodeficiency Virus, run by GlaxoSmithKline 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 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: stopped early, as of the sponsor's last update on 9 May 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 was stopped early. Results are not available in the source record.
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?
Adverse events (AEs) assessments (time frame: Up to approximately 7 weeks). The study lists 5 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 9 May 2017.
