Evaluation of Switch to Dolutegravir/Lamivudine (DTG/3TC) From Current Suppressive Antiretroviral Therapy in People Living With HIV (PLWH) Receiving Opioid Agonist Therapy (OAT) (NCT06580873)

🩺 Plain-English Summary (8th-Grade Level)

The goal of this clinical trial is to determine the efficacy of Dolutegravir/Lamivudine (DTG/3TC), or "Dovato", in virally-suppressed (HIV-1 RNA \< 200 copies/mL) individuals receiving opioid agonist therapy such as methadone, buprenorphine, slow-release morphine, after switching from their current suppressive antiretroviral therapy (ART). The main questions this trial seeks to answer are: 1. whether people living with HIV-1 (PLWH) on opioid agonist therapy (OAT) remain virally suppressed after switching to DTG/3TC from their current suppressive ART 48 weeks post-switch; 2. the number and type of adverse events (AEs) and serious adverse events (SAEs) attributable to DTG/3TC as documented per standard process at each study visit, and any discontinuations of DTG/3TC due to AEs and SAEs as determined by the study investigator; 3. the number of dosing changes in OAT attributable to DTG/3TC as determined by the study investigator and documented as per standard progress at each study visit; 4. the number of persons with any recreational or non-prescribed substances in their urine drug screens who remain virally suppressed (HIV-1 RNA \< 200 copies/mL) at 48 weeks post-switch from current suppressive ART to DTG/3TC; 5. any change from baseline values (i.e., day 0) to 48 weeks post-switch from current suppressive ART to DTG/3TC of serum creatinine and non-fasting lipid parameters; 6. any change from baseline value (i.e., day 0) to 48 weeks post-switch from current suppressive ART to DTG/3TC in HIV Treatment Satisfaction Questionnaire (Status) (HIVTSQs) scores; 7. the number of persons who remain virally suppressed (HIV RNA \< 200 copies/mL) at 48 weeks post-switch from current suppressive ART to DTG/3TC in conjunction with differing levels of adherence to DTG/3TC, and; 8. the number of persons who experience symptoms of opioid withdrawal or overdose per standardized survey or by self-report (e.g., overdose events) During the course of the study, participants will complete: * A set of questionnaires * Blood draws * A review of adverse events and concomitant medications * ECG scans at screening and 48 weeks * Urine drug screening * Physical exams * Review of alcohol consumption
