Study Description

Brief Summary:

The investigators hypothesize that following virological failure of a standard NNRTI+2N(T)RTI regimen second-line antiretroviral therapy consisting of ritonavir-boosted lopinavir and 2N(T)RTIs will offer comparable efficacy to that provided by ritonavir-boosted lopinavir and raltegravir.

The study will be conducted for 96-weeks with the primary endpoint analyzed after 48-weeks.

The primary endpoint is virological: a comparison of virological suppression in plasma < 200 copies/mL between the randomized arms after 48 weeks.

Secondary and exploratory endpoints include virological, immunological, safety, clinical, metabolic, drug adherence, drug resistance and quality of life.

Condition or disease	Intervention/treatment	Phase
HIV Infections	Drug: raltegravir Drug: 2N(t)RTI Drug: Ritonavir-boosted lopinavir	Phase 4

Detailed Description:

In HIV-infected subjects who have virologically failed first-line antiretroviral therapy comprising 2N(t)RTI + NNRTI a regimen of second-line therapy incorporating ritonavir-boosted lopinavir and raltegravir provides comparable (i.e., non-inferior) antiretroviral efficacy over 48 weeks to a regimen containing ritonavir-boosted lopinavir and 2-3N(t)RTIs.

Eligible patients will be randomised to one of two arms:

I. ritonavir boosted lopinavir (LPV/r) 200mg/50mg 4 tabs once daily or 2 tabs twice daily + 2-3N(t)RTIs

II. ritonavir boosted lopinavir (LPV/r) 200mg/50mg 4 tabs once daily or 2 tabs twice daily + raltegravir 400 mg twice daily

The primary objective of this study is to compare the virological efficacy of the two strategies as measured by the proportion of participants with HIV RNA < 200 copies/mL 48 weeks after randomisation.

Secondary objectives include virological, immunological, safety and antiretroviral therapy endpoints.

Exploratory endpoints include clinical, metabolic, drug resistance, medication adherence and quality of life endpoints.

Arms and Interventions

Arm	Intervention/treatment
Active Comparator: Ritonavir-boosted lopinavir and 2N(t)RTI This is the current standard of care for second line therapy following failure of standard first-line NNRTI+2N(t)RTIs according to WHO guidelines.	Drug: 2N(t)RTI 2N(t)RTIs as prescribed Other Name: nucleosides, nucleotides, nuncleoside backbone Drug: Ritonavir-boosted lopinavir 2 heat-stable tablets of ritonavir-boosted lopinavir taken every 12 hours Other Name: Aluvia, Kaletra
Experimental: Ritonavir-boosted lopinavir and raltegravir This is an experimental arm which is likely to be fully active in the presence of N(t)RTI mutations and which preliminary evidence suggests should be potent and durable.	Drug: raltegravir 400 mg raltegravir tablet taken every 12 hours Other Name: Isentress Drug: Ritonavir-boosted lopinavir 2 heat-stable tablets of ritonavir-boosted lopinavir taken every 12 hours Other Name: Aluvia, Kaletra

Outcome Measures

Primary Outcome Measures :

Participants With Plasma HIV RNA < 200 Copies/mL 48 Weeks After Randomization [ Time Frame: 48 weeks following randomization ]

Secondary Outcome Measures :

Participants With Plasma HIV RNA < 200 Copies/mL 48 Weeks After Randomization, Per-protocol Population [ Time Frame: 48 weeks ]
The per- protocol population includes those participants who fulfil the protocol in the terms of the eligibility, interventions, and outcome assessment
Participants With Plasma HIV RNA < 200 Copies/mL 48 Weeks After Randomization, Per-protocol Population, Non-completer Classed as Failure [ Time Frame: 48 weeks ]
The non-completer classed as failure analysis will include all randomised participants; participants who meet the following criteria will be defined as failures:

i. week 48 HIV RNA being above each threshold ii. has missing HIV-1 RNA data for any reason iii. stops randomly assigned therapy
Participants With Plasma HIV RNA < 200 Copies/mL 48 Weeks After Randomization, Per-protocol Population, Baseline VL >100,000 Copies Per mL [ Time Frame: 48 weeks ]
The difference between treatment arms in proportion of participants with plasma HIV RNA < 200 copies/mL 48 weeks after randomization, per-protocol population: stratified analysis by baseline plasma viral load (less than or equal to 100,000 copies per mL or >100,000 copies per mL) on those participants who fulfil the protocol in the terms of the eligibility, interventions, and outcome assessment
Participants With Plasma HIV RNA < 200 Copies/mL 48 Weeks After Randomization, Per-protocol Population, VL Less Than or Equal to 100,000 Copies Per mL [ Time Frame: 48 weeks ]
The per- protocol population includes those participants who fulfil the protocol in the terms of the eligibility, interventions, and outcome assessment
