Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

MARCH is an international, multicentre trial planning to enroll 380 HIV-1 infected patients who are currently on 2N(t)RTI + PI/r regimen and virologically suppressed. Participants will be randomized (1:2:2) to one of three treatment groups: to continue their current treatment regimen, maraviroc dose at 150 mg twice daily with PI/r, or maraviroc at 300 mg twice daily with 2N(t)RTI. As the participants population have HIV RNA \<200 copies/mL, the phenotypic assessment of tropism cannot be used to determine tropism, instead we will employ the genotypic assessment of tropism by sequencing the V3 loop of the HIV envelope. The main aim of this study is to investigate whether switching to maraviroc, in combination with either RTI or PI/r, is as good at keeping the HIV viral load undetectable as the combination of RTI with PI/r. The other aim is to see if switching to these combinations with maraviroc will improve some of the side effects that can be seen when people take combination therapy including RTI and PI/r.

The study hypothesis is that in stable, virologically suppressed (plasma HIV-RNA \<200 copies/mL) patients with no history of prior virological failure, a switch to either MVC dosed at 300mg twice daily (bid) combined with the same 2N(t)RTI backbone regimen or MVC dosed at 150mg twice daily (bid) with the current PI/r (or 300mg bid at the discretion of the investigator if the PI/r is fosamprenavir/r) provides similar (non-inferior) antiretroviral efficacy compared to continuation of the current 2N(t)RTI + PI/r regimen.

Group Type ACTIVE_COMPARATOR

Maraviroc

Intervention Type DRUG

Maraviroc is a marketed drug for the treatment of HIV-infection. Maraviroc will be supplied in two different oral dose forms, 150mg and 300mg given twice a day. The drug will be dosed according to the recommendations in the product label i.e. with PI/r the dose is 150mg bid except, Maraviroc 300mg bid can be used at the discretion of the investigator if the PI/r is fosamprenavir/r; those randomised to the 2N(t)RTI arm, will receive Maraviroc 300mg bid. Patients randomised to receive Maraviroc will be provided with bottles of Maraviroc which contain a 30-day supply.

Replace PI/r drugs with Maraviroc

Replace PI/r drugs with MVC at a dose of 300mg bid and continue 2N(t)RTI.

* Provision of written, informed consent.

Exclusion Criteria

* CXCR4 or CCR5/CXCR4 dual tropic HIV tropism or a non-reportable tropism result based on assessment using proviral DNA
* Anticipated need to modify current cART regimen for toxicity management in the next 6 months
