What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers are testing whether switching from a standard three-drug HIV regimen to a two-drug regimen keeps the virus under control just as well. The trial enrolls 134 adults whose HIV is already suppressed on a three-drug regimen and randomly assigns them to continue that regimen or switch to a two-drug combination. Over 48 weeks, researchers measure intact, replication-competent HIV in immune cells, along with inflammation markers and immune function, to see whether the two-drug approach is a safe long-term alternative.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
two-drug HIV regimen (dolutegravir plus lamivudine) compared with a three-drug regimen (bictegravir, tenofovir alafenamide, emtricitabine)
What this could lead to
If the two-drug regimen matches the three-drug regimen, people with HIV could control the virus with fewer medicines and less long-term drug exposure.
What could go wrong
The trial may find the two-drug regimen leaves more intact virus or more inflammation than the three-drug regimen. The 48-week main comparison is relatively short for a lifelong infection, and 134 participants is a modest sample.

Inclusion Criteria: * Age = or \>18 years. * Ability and willingness to provide written informed consent. * Ability to attend the complete schedule of assessments and patient visits. * Ability and willingness to have blood samples collected and stored indefinitely and used for various research purposes. * HIV RNA \< 50 copies/mL for at least 3 months on a 2nd generation INSTI based regimen. * Females of childbearing potential should be on effective contraception Exclusion Criteria: * Current presence of opportunistic infection (AIDS defining events as defined in category C of the CDC clinical classification). * Evidence of active HBV infection (Hepatitis B surface antigen positive or HBV viral load positive in the past and no evidence of subsequent seroconversion (seroconversion= HBV antigen or viral load negative and positive HBV surface antibody). * Evidence of active HCV infection: HCV antibody positive result within 60 days prior to study entry with positive HCV viral load or, if the HCV antibody result is negative, a positive HCV RNA result within 60 days prior to study entry. * Pregnancy or breastfeeding. * Patients unable to understand the study protocol or any other condition that in the investigator's opinion may compromise compliance with the study protocol * Decompensated liver cirrhosis (Child-Pugh B/C) * Unstable liver disease (as defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices, or persistent jaundice), cirrhosis, known biliary abnormalities (apart from hyperbilirubinemia or jaundice due to Gilbert's syndrome or asymptomatic gallstones) * Psychiatric and psychological disorders, which in the opinion of the investigator, will interfere with the trial conduct or safety of the participant. * Previous participation in a trial evaluating an immune modulating agent. * Active drug or alcohol use/addiction such that, in the opinion of the site investigator, would interfere with adherence to study requirements. * Treatment failure on an integrase inhibitor containing regimen and reported baseline resistance * Creatinine Clearance \<50 * Tuberculosis treatment * Documented M184V * Previous virological failure \>200 copies/mL on NRTI * Subjects with history or presence of allergy to any of the study drugs or their components * ALT \>5 times the ULN, OR ALT \>3xULN and bilirubin \>1.5xULN (with \>35% direct bilirubin)
