Researchers are looking for new treatments for HIV-1 (human immunodeficiency virus type 1) that are safe, well-tolerated, and can be taken less often. HIV-1 is the most common type of HIV, which is a virus that attacks cells of the immune system. Ulonivirine (MK-8507) is a study medicine designed to treat HIV-1 The goal of this study is to learn if ulonivirine does not increase the QT interval (a measure of heart rhythm on an electrocardiogram) above a certain amount. Researchers also want to learn what happens to the amount of ulonivirine in a healthy person's body over time.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
This trial has completed. Results may be available via ClinicalTrials.gov or peer-reviewed publications.
Merck & Co (MRK) is the sponsoring company for this trial. BiotechSign currently grades this company C (52/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
