Can stronger HIV drug doses flush out the virus that hides?
NCT ID NCT06640192
First seen Oct 20, 2026 · Last updated Oct 21, 2026 · Updated 1 time
Summary
HIV drugs keep the virus in check, but the virus hides in a latent reservoir, mostly in lymph tissue, and that reservoir is the main barrier to a cure. Researchers are testing whether giving three HIV drugs at higher-than-usual doses can push more drug into lymph tissue and reduce the size of that hidden reservoir. The trial enrolls 18 adults with HIV and compares standard triple therapy with high-dose dolutegravir, maraviroc and lamivudine. Researchers measure viral DNA in blood and lymph tissue to see whether the reservoir shrinks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a high-dose combination of three HIV drugs: dolutegravir, maraviroc and lamivudine
- What this could lead to
- If higher drug doses reach hidden virus in lymph tissue and shrink the reservoir, this could point toward a strategy for a durable, treatment-free remission of HIV.
- What could go wrong
- This is a small phase 2 trial with 18 participants, so any effect may not hold in larger groups. Higher doses may cause more side effects, and shrinking the reservoir does not guarantee the virus stays suppressed without standard treatment.

Inclusion Criteria: * Patients who, after receiving information about the study design, the aims of the study, the possible risks that may arise from it and the fact that they can refuse to collaborate at any time, give written consent to participate in the study. * Be over 18 years of age and under 60 years of age. * Understand the purpose of the study and be available to perform the visits and procedures established in the protocol. * Persons with HIV being followed up in HIV consultations. * Antiretroviral treatment with a triple regimen containing an integrase inhibitor. * Undetectable plasma viral load (\<50 copies of HIV RNA in blood plasma) for at least 12 months prior to inclusion. * No history of prior virologic failure. * No known gastrointestinal disease. * R5 viral tropism, determined on proviral DNA. * In women: negative urine pregnancy test performed within 7 days prior to the start of study treatment in women of childbearing age and if \< 2 years post menopause. * Women of childbearing age and male partners of childbearing age must agree to use a highly effective method of contraception (such as surgical sterilization, double barrier method, oral contraceptives, or hormonal contraceptive implants) and to continue using them until 6 months after the last dose of treatment. Exclusion Criteria: * Chronic Hepatitis B (HBsAg +) * Untreated chronic hepatitis C * Viral tropism X4 * Pregnancy or planning to become pregnant during the course of the study. * Lactation. * Abnormal coagulation parameters (PT\> or equal to 1.2 LSN). * Thrombocytopenia (platelet count \<50000). * Transaminases in values greater than 3 times normal. * Impaired renal function (plasma creatinine \>1.5 mg/dl, creatinine clearance \<60 ml/min/1.73 m2). * Contraindications for the performance of any of the study procedures (colonoscopy/bowel biopsy) or conscious sedation. * Anemia (greater than or equal to grade 1). * Administration of aspirin, ibuprofen, warfarin or other agents that interfere with the coagulation cascade are prohibited 1 week before endoscopy. * Concomitant treatment with cytochrome CYP3A inducers or inhibitors. * Patients in whom there is a contraindication for use according to the established in the technical data sheet or known hypersensitivity to the drugs under investigation or who, according to the investigator's criteria, it is not advisable to participate.
