About this study

Official title: A 2-Part, Phase I, Single Dose, Crossover Relative Bioavailability Study of Both TIVICAY 10 mg Conventional Tablets and 5 mg Dispersible Tablets Compared to Conventional TIVICAY Tablets in Fasted Healthy Adult Subjects

The aim of this cross-over study is to compare the relative bioavailability and pharmacokinetic parameters of both 10 mg conventional tablets and 5 mg dispersible tablets of dolutegravir (DTG) with that of 25 mg or 50 mg conventional DTG tablets. The study will be carried out in 2 parts. Part 1 of the study will be open-label, 2 period designs with a wash out period of at least 7 days between the dosing periods. Subjects will be randomized to receive either single dose of five 10 mg DTG tablets or one 50 mg DTG tablet in a crossover manner in the fasting state. Part 2 of the study will be a 3 period crossover design with a wash out period of at least 7 days between the dosing periods. Subjects will be randomized to receive either single dose of five 5 mg DTG tablets (administered as dispersed with water or directly to mouth) or one 25 mg DTG tablet in a crossover manner in the fasting state. Subjects will have a follow-up visit 7-10 days post last dose of study treatment. Approximately 14 healthy subjects will participate in Part 1 and approximately 24 healthy subjects will participate in Part 2 of the study. The total duration of Part 1 will be approximately 7 to 8 weeks and that of part 2 will be approximately 8 to 9 weeks.

A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acid pH (5.0 - 6.0). Urine samples were collected for the measurement of urine pH by dipstick method up-to follow-up (Day 25) in Part 1. Only categories with significant values have been presented. Only those participants with data available at the specified time were analyzed (represented by n=x,x in the category titles).

The concentration of the excreted molecules determines the urine's specific gravity. Urine samples were collected for the measurement of urine specific gravity by dipstick method up-to follow-up (Day 25) in Part 1. Only categories with significant values have been presented. Only those participants with data available at the specified time were analyzed (represented by n=x,x in the category titles).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Conventional dolutegravir 10 mg tablet, Conventional dolutegravir 50 mg tablet and Dispersible dolutegravir 5 mg tablet in people with HIV Infections, 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 5 inclusion and 14 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 23 Jul 2019. 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?

Yes. Results are posted in the registry (first posted 21 Dec 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Area Under the Plasma Concentration-time Curve From Time of Dose Extrapolated to Infinite Time (AUC[0-infinity]) of DTG for Part 1 (time frame: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 12, 16, 24, 48, and 72 hours post-dose in Part 1). The study lists 4 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 NCT03095638, 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 23 Jul 2019.
