About this study

Official title: A Multiple Dose Clinical Trial to Study the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of MK-1972 in HIV-1 Infected Patients

This is a two part study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of MK-1972 in participants with HIV-1 infections. In Part 1, participants will be randomized to receive MK-1972 (at one of 5 different dose levels given once or twice per day) or placebo. Part II will begin after the results of Part I are known; participants will be randomized to receive MK-1972 (only one dose level, twice per day) or placebo. The primary hypotheses are that MK-1972 at the studied doses is safe and well tolerated in HIV-1 infected males; and that MK-1972 has superior antiretroviral activity compared to placebo.

Conditions: HIV-1 Infection
Being tested: MK-1972, Placebo to MK-1972

What participants receive

What is being measured

The primary outcome is the main question the study is designed to answer.

Number of Participants Experiencing Clinical and Laboratory Adverse Events (AEs)
An adverse event is any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR's product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the SPONSOR's product, is also an adverse event.
Measured: From consent to 14 days after the last dose (up to Day 24)
Change From Baseline to Day 10 in Plasma Human Immunodeficiency Virus (HIV)-1 Ribonucleic Acid (RNA) Due to Treatment With MK-1972 or Placebo
Blood was collected at baseline and on Day 10, and the plasma concentration for HIV-1 RNA was determined using the Abbott RealTime HIV assay.
Measured: Baseline and Day 10 (24 hours post-dose)

Secondary outcomes (1)

The Area Under the Curve From 0-24 Hours (AUC0-24hrs) on Day 10 for Plasma Concentration of MK-1972 in Participants With HIV-1 Infection
Plasma concentration of MK-1972 was determined from blood collected from HIV-1 infected participants on Day 10 : pre-dose up to 24 hours post-dose in order to determine the AUC0-24hrs.
Measured: Day 10: pre-dose, and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 16, and 24 hours post-dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MK-1972 in people with HIV-1 Infection, run by Merck Sharp & Dohme LLC.

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 6 inclusion and 16 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 29 Aug 2018. 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. Some participants in this study may receive a placebo. 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 5 Feb 2016). 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?

Number of Participants Experiencing Clinical and Laboratory Adverse Events (AEs) (time frame: From consent to 14 days after the last dose (up to Day 24)). 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 NCT01353898.

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 29 Aug 2018; AzTrials last refreshed its copy on 7 Nov 2026.
