Study information
Scientific title
A randomised controlled trial to evaluate options for second-line therapy in patients failing a first-line 2 nucleoside reverse transcriptase inhibitors (2NRTI) and non-nucleoside reverse transcriptase inhibitor (NNRTI) regimen in Africa
Acronym
EARNEST
Study hypothesis
The trial aims to determine whether, in patients failing a first-line nucleoside reverse transcriptase inhibitor (NRTI) and non-nucleoside reverse transcriptase inhibitor (NNRTI)-containing regimen:
1. The use of boosted protease inhibitor (bPI) plus raltegravir (an integrase inhibitor) is superior to standard of care (bPI plus two new NRTIs) in achieving good human immunodeficiency virus (HIV) disease control at 96 weeks after randomisation
2. The use of bPI monotherapy is non-inferior to standard of care in achieving good HIV disease control at 96 weeks after randomisation

Condition
Human immunodeficiency virus (HIV)
Intervention
Arm A (bPI + NRTIs):
Patients randomised to this arm will receive Aluvia® (lopinavir/ritonavir 400 mg/100 mg) twice daily and 2 NRTIs. The choice of NRTIs will be at the discretion of the managing clinician and based on the local standard of care and drug availability, taking into account patient's previous drug exposure and side effects on first-line therapy. For patients who have been treated with a first-line regimen containing stavudine or zidovudine, clinicians will be encouraged to follow the current World Health Organization (WHO) recommendations for second-line treatment regimens of either:
1. Tenofovir with emtricitabine (Truvada®) or lamivudine
2. Didanosine with abacavir
The NRTIs will be given in the following standard doses:
Tenofovir - 300 mg once daily
Emtricitabine - 200 mg once daily
Lamivudine - 150 mg twice daily or 300 mg once daily
Didanosine - 400 mg once daily (250 mg once daily if weight is less than 60 kg)
Abacavir - 300 mg twice daily or 600 mg once daily
Zidovudine - 300 mg twice daily
Arm B (bPI + raltegravir):
Patients randomised to this arm will receive Aluvia® (lopinavir/ritonavir 400 mg/100 mg) twice daily and raltegravir 400 mg twice daily.
Arm C (bPI monotherapy):
Patients randomised to this arm will receive Aluvia® (lopinavir/ritonavir 400 mg/100 mg) twice daily (and raltegravir 400 mg twice daily for the first 12 weeks only). If patients interrupt treatment for more than 4 weeks (in induction phase or in Aluvia® monotherapy phase), treatment will be resumed with a further induction period of raltegravir for the first 12 weeks.
Patients will be randomised to receive study drugs according to the treatment arms. Treatment will be open-label, and will be distributed at 4 to 16 weekly intervals from a dedicated supply of study drugs that will be stored separately from routine clinic drug supplies in a designated section of the research pharmacy at the study site. Each patient will be treated and followed up for a total of 144 weeks regardless of which arm of the trial they are randomised to. All trial drugs will be in tablet form.

Eligibility
Participant inclusion criteria

4. Naive to protease inhibitor therapy
5. Good adherence to anti-retroviral therapy (ART) in the 12 weeks prior to screening defined as no more than 10% of doses missed (patients who do not have good adherence should be given adherence
counselling and re-assessed after an appropriate time interval of not less than 4 weeks)
6. Clinically stable and receiving treatment for any known opportunistic infections
7. HIV treatment failure defined by the one or more of the following clinical, immunological and virological criteria (modified from World Health Organization [WHO] 2006 criteria):
7.1. Clinical: A1 and A2 and A3 must be fulfilled:
A1: New or recurrent WHO stage 4 condition occurring after at least 12 months on ART
A2: CD4 cell count less than 200 cells/mm^3 after at least 12 months on ART, and confirmed at screening
A3: Viral load (VL) greater than 400 copies/ml at screening
7.2. Immunological: (B1 or B2 or B3) and B4 must be fulfilled:
B1: Fall of CD4 count to pre-therapy baseline (or below) after at least 12 months on ART and confirmed at screening
B2: Fall of CD4 count from previous value greater than 400 cells on treatment (x 2) to less than 200 cells/mm3 after at least 12 months on ART and confirmed at screening
B3: CD4 count less than 100 cells after at least 12 months on ART and confirmed at screening
B4: VL greater than 400 copies/ml at screening
7.3. Virological: VL greater than 10,000 copies/ml after at least 6 months on ART, and confirmed at screening after at least 12 months on ART
