A Study of MK-8527 in Human Immunodeficiency Type 1 Virus (HIV-1) Infected Participants (MK-8527-002)

This study will evaluate the anti-retroviral activity of MK-8527 in HIV-1 infected, ART-naïve participants. The primary hypothesis is that MK-8527 has superior anti-retroviral activity compared to placebo, as measured by change from baseline in plasma HIV-1 ribonucleic acid (RNA) at 168 hours postdose.

Primary outcomes

  1. Change From Baseline in Plasma HIV-1 RNA

    Time frame: Baseline and 168 hours postdose

    Blood samples were taken to determine HIV-1 RNA levels at Predose (baseline) and 168 hours postdose. Data were fitted with a longitudinal data analysis (LDA) model containing fixed effects for treatment, time and treatment by time interaction, and a random effect for participant.The change from baseline in plasma HIV-1 RNA in participants administered MK-8527 was calculated and results were compared with historical placebo data.

  2. Percentage of Participants Who Report 1 or More Adverse Events (AEs)

    Time frame: Up to 28 days

    An AE is defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with the treatment. An AE is any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with use of a medicinal product, regardless of whether or not it is considered related to the medicinal product. The percentage of participants that reported at least 1 AE will be summarized.

  3. Percentage of Participants Who Were Discontinued From the Study Due to an AE

    Time frame: Up to 28 days

    An AE is defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with the treatment. An AE is any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with use of a medicinal product, regardless of whether or not it is considered related to the medicinal product. The percentage of participants that were discontinued from the study due to an AE will be summarized.
