ANRS 12372 MODERATO

Details and patient eligibility

About

MODERATO is a phase III, open-label, randomized, multicenter, non-inferiority trial conducted in West and Central Africa (Cameroon, Côte d'Ivoire, Burkina Faso).

HIV-1 infected adults receiving first line ART with TDF+XTC+EFV or DTG+XTC+TDF virologically suppressed will be recruited and followed during 100 weeks.

The objective is to assess the non-inferiority of a strategy consisting of switching to a dual maintenance therapy (DTG+3TC or ATV/r+3TC), comparing to WHO standard first line regimen (TDF+3TC+EFV or DTG+3TC+TDF), in terms of virological success at 96 weeks

Full description

In HIV-1 infected adults receiving first line ART with TDF+XTC+EFV or DTG+XTC+TDF virologically suppressed (viral load < detection limit of the technique used) for at least two years: to assess the non-inferiority of a strategy consisting of switching to a dual maintenance therapy (DTG+ 3TC or ATV/r+3TC), comparing to WHO standard first line regimen (TDF+3TC+EFV or DTG+3TC+TDF), in terms of virological success at 96 weeks, in Cameroon, Côte d'Ivoire and Burkina Faso.

This is a trial including two strategies (dual maintenance therapy and triple reference therapy) and three ART regimens (DTG+3TC and ATV/r+3TC used in the maintenance strategy and TDF+3TC+EFV/ DTG+3TC+TDF used in the reference strategy).

The primary analysis will compare the two strategies. Secondary analyses will compare the three ART regimens two by two.

In order to make these secondary analyses possible, participants will be randomly assigned, at inclusion, to each of the three ART regimens (arm 1: DTG+3TC; arm 2: ATV/r+3TC; arm 3: TDF+3TC+EFV / DTG+3TC+TDF). The maintenance strategy will include arm 1 and 2. The reference strategy will include arm 3

Number of participants : 480 (160 in each ART regimen, ie 320 in the dual maintenance therapy strategy and 160 in the triple therapy reference strategy)

The primary endpoint is treatment success, as defined by using the FDA snapshot algorithm : patients who are still continuing the assigned strategy and whose last available plasma HIV-1 RNA in the the window analysis (90 to 102 weeks) is <50 copies/ml at the end of the window analysis (90 to 102 weeks)

Enrollment: 480 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
