Early DOlutegravir/LAmivudine Switching after virological suppression (EDOLAS Study)

Efficacy and safety of early switching to dolutegravir/lamivudine (DTG/3TC) from INSTI-based three-drug regimens in HIV-1-infected adults previously naïve who achieve virological suppression

Brief summary (registry, in English)

• To evaluate efficacy and safety of an early switch to a two-drug regimen with DTG/3TC as single pill in participants who achieved and maintained a recent (less than 1 year) virological suppression with a three-drug INSTI-based ART, compared to continuing the INSTI-based three-drug first-line regimen. The primary analysis will be performed on the intention-to-treat (ITT) population as the proportion of participants with virologic rebound (one HIV-1 RNA 50 copies/mL) at Week 48 as defined by the US Food and Drug Administration (FDA) snapshot algorithm (non-inferiority margin 4%). An exploratory interim analysis will be performed after 50% of participants have completed 24 weeks of follow-up. After 48 weeks all the participants actively followed in the control group will switch to DTG/3TC as single pill (delayed switch), and the final evaluation will be performed after 96 weeks.

Copied verbatim from EU CTIS (euclinicaltrials.eu) and grouped by topic. Only the trial team decides who can take part.

Lab values

  • Having failed virologically • Having changed the INSTI drug • Any major INSTI- or NRTI-resistance-associated mutation documented before starting ART • Pregnancy or breast-feeding • HBsAg positivity • HCV-RNA positivity needing for any hepatitis C virus (HCV) therapy during the study • An active malignancy or opportunistic infection requiring active treatment • Women of childbearing potential not adopting an effective birth control system throughout the study period • Creatinine clearance of <50 mL/min/1.73m2 via CKD-EPI method • A life expectancy <2 years • Use of HIV immunotherapeutic vaccines; other experimental agents, ART drugs not otherwise specified in the protocol, cytotoxic chemotherapy, systemically administered immunomodulators • Individuals who in the investigator’s judgment, poses a significant suicidality risk; • Major Depression, Bipolar Disorders and Psychoses

Who the study is looking for

  • HIV-1 documented infection • Age 18 years • To be treated as ART naïve for overall less than 18 months before screening/baseline • To receive a stable (not changed) INSTI-based first-line three-drug ART (see Target Population section for regimens allowed); switch between different NRTIs are allowed • To have reached a HIV-1 RNA <50 copies/mL during INSTI first-line therapy for less than 12 months. At least a single HIV-1 RNA determination below the threshold within the 6 months before enrollment is required (if a following determination in present, this should not be 50 copies (cp)/mL) • Evidence of HbsAg negative less than 18 months before screening/baseline • No known allergy or intolerance to NRTIs, or INSTIs • Being able to comply with the protocol requirements • Informed consent signed
