New HIV prevention strategy for pregnant women could eliminate need for common drugs
NCT ID NCT02738502
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a single HIV drug, darunavir/ritonavir, could replace the usual combination therapy in pregnant women with well-controlled HIV. The goal was to prevent mother-to-child transmission without using a class of drugs called NRTIs. 91 pregnant women already on HIV treatment and with undetectable virus levels participated. The approach aims to simplify treatment while keeping the baby safe.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- darunavir/ritonavir (DRV/r) monotherapy
- What this could lead to
- If successful, this could offer a simpler, NRTI-free treatment option for pregnant women with HIV to prevent mother-to-child transmission.
- What could go wrong
- This is a small, early-phase pilot study with only 91 participants, so results may not apply broadly. The monotherapy may fail to keep viral load suppressed, risking transmission.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Pregnant woman, under 15 weeks gestational age at screening * Documented Human Immunodeficiency Virus (HIV) HIV-1 infection (serology and/or plasma HIV RNA viral load) * Current treatment with at least two ARVs * Virological suppression for at least 12 months, defined by a PVL \< 50 copies / mL. A blip (transiently ≥ 50 but \< 400 copies/mL) will not be considered as an exclusion criterion, if it is followed by 2 successive controls with CV \< 50 at least one month before enrollment * Plasma viral load \< 50 copies/mL at pre-inclusion * CD4 ≥ 250 cells/mm3 at pre-inclusion * Informed written consent * Health care coverage Inclusion criteria for the child : * Mother enrolled in the trial * Informed written consent by parents or legal guardians Exclusion Criteria: * Infection by HIV-2 * History of treatment failure and/or resistance with any Protease Inhibitor (PI). Treatment failure is defined by a viral replication (≥ 50 copies/mL) during antiretroviral treatment. An increasing CV due to treatment interruption will not be considered as a failure, providing that the absence of resistance mutations to at least one PI can be confirmed by genotyping. * Documented CD4 lymphocyte less than 200/mm3 * Known intolerance to darunavir or ritonavir * Hepatitis B Virus (HBV) co-infection (HBs Ag-positive and/or detectable HBV DNA) on therapy with analogs (tenofovir, emtricitabine, lamivudine) * Known resistance of maternal viral strain to darunavir or nevirapine * Intended absence (travel abroad, moving ...) * Expected delivery in a maternity hospital not participating in the trial * Participation in the trial during previous pregnancy * Persons under guardianship or deprived of liberty by a judicial or administrative decision Exclusion criteria for the child: * Refusal by parent (s) or legal guardian (s)
