Between July 2006 and May 2008, we enrolled pregnant women with HIV-1 infection in the Mma Bana Study (meaning “mother of the baby” in Setswana) in southern Botswana. Women with CD4+ cell counts of 200 or more were randomly assigned (in permuted blocks stratified according to clinical site) to receive either 300 mg of abacavir, 300 mg of zidovudine, and 150 mg of lamivudine coformulated as Trizivir (GlaxoSmith-Kline) twice daily (the NRTI group) or 400 mg of lopinavir and 100 mg of ritonavir coformulated as Kaletra (Abbott) with 300 mg of zidovudine and 150 mg of lamivudine coformulated as Combivir (GlaxoSmithKline) twice daily (the protease-inhibitor group). Women with CD4+ cell counts of less than 200 cells per cubic millimeter or with an acquired immunodeficiency syndrome (AIDS)–defining illness received standard-of-care treatment for Botswana: 200 mg of nevirapine, 300 mg of zidovudine, and 150 mg of lamivudine twice daily (after a 2-week lead-in period of oncedaily nevirapine at a dose of 200 mg) (the observational group). Women in the randomized groups began to receive HAART between 26 and 34 weeks’ gestation and continued it through weaning or 6 months post partum (whichever occurred first), and women in the observational group began to receive HAART between 18 and 34 weeks’ gestation and continued treatment indefinitely. We report results for the primary end points at 6 months post partum.
Infants received single-dose nevirapine (6 mg) at birth and received zidovudine (4 mg per kilogram of body weight twice daily) from birth through 4 weeks. Women were counseled to exclusively breast-feed and to complete weaning 3 days before the 6-month study visit. Infants were provided free formula and foods from the time of weaning (whenever it occurred) through 12 months.
Study drugs were provided by GlaxoSmith-Kline (Trizivir and Combivir) and Abbott Pharmaceuticals (Kaletra), but these companies had no other role in the design of the study, the accrual or analysis of the data, the preparation of the manuscript, or the decision to submit the manuscript for publication. The Botswana government provided nevirapine, Combivir, additional medications, and some laboratory testing. The Health Research Development Committee of Botswana and the Human Subjects Committee of the Harvard School of Public Health approved the study protocol and amendments. An independent data and safety monitoring board reviewed safety and efficacy data approximately every 6 months. The full study protocol including the statistical-analysis plan, is available with the full text of this article at NEJM.org. All authors vouch for the completeness and veracity of the reported data and analyses and attest that the study as reported conforms with the protocol.

We conducted a randomized, open-label, non-inferiority trial between June 2010 and December 2013 at Rahima Moosa Mother and Child Hospital in Johannesburg, South Africa. Children were randomized to switch to efavirenz-based therapy or to continue on ritonavir-boosted lopinavir-based therapy and were followed for 48 weeks after randomization. The non-inferiority design was chosen as efavirenz was not expected to have better virologic outcomes than the standard regimen. The study was approved by the Institutional Review Boards of Columbia University and the University of the Witwatersrand. The child’s mother or legal guardian provided signed informed consent.
Children were eligible for enrollment if they had nevirapine exposure as part of PMTCT, were currently receiving ritonavir-boosted lopinavir-based therapy started <36 months of age provided for at least one year, and had an HIV RNA test <50 copies/ml. All children in the control arm of our prior trial10 (link),11 (link) still in follow-up were screened for eligibility. In addition, clinicians responsible for the care of HIV-infected children at other clinics in the area were approached about referring children meeting our eligibility criteria. Random assignments were generated by the study statistician using a permuted block design with block sizes between 8 and 12 and were concealed in opaque envelopes opened on-site at the time of randomization. Children were followed at 4, 8, 16, 24, 32, 40, and 48 weeks after randomization.

The PubMed/MEDLINE, Embase, and Cochrane databases were systematically searched (up to August 2013) to identify randomized controlled trials (RCTs) evaluating efficacy and/or safety of ATV/r, DRV/r, DTG, EFV, EVG/c, LPV/r, RAL, or RPV in treatment-naive HIV-1 patients. PubMed and EMBASE search terms were “HIV-1 [mesh] OR HIV infections [mesh] NOT pregnancy [mesh] AND ((dolutegravir OR GSK1349572) OR (efavirenz OR Sustiva OR Stocrin OR DMP-266) OR (raltegravir OR Isentress OR MK-0518) OR (elvitegravir OR GS-9137 OR JTK-303) OR (rilpivirine OR Edurant OR TMC 278) OR (darunavir OR Prezista OR TMC-114) OR (atazanavir OR Reyataz OR BMS-232632) OR (lopinavir OR ABT-378 OR Aluviran OR Koletra OR Kaletra) OR (Atripla OR Quad OR Stribild OR Eviplera OR Complera))”. The ClinicalTrials.gov registry, US FDA summary basis of approvals, EMA EPAR scientific discussions, and references of published systematic reviews and meta-analyses were also searched for any additional data. Abstracts of the 2013 meeting of the International AIDS Society and the Interscience Conference on Antimicrobial Agents and Chemotherapy were searched to identify recent presentations. Two phase 3 studies of DTG with data available after August 2013 were also included.
Study selection was conducted by two independent researchers who performed an initial review and selection of study titles/abstracts followed by full text review and selection. Disagreements between the reviewers were resolved by consensus. Pre-specified inclusion criteria included treatment-naive patients with HIV-1 infection; studies published in English; phase 3 or 4 RCT; patients aged ≥13 years; use of at least one of the third agents of interest; and reporting at least one of the efficacy outcomes of interest after 48 weeks of treatment. Non-randomized observational studies; single-arm studies; and studies examining different dosages of the same drug, structured treatment interruptions, maintenance treatments, or treatment switching were excluded, as were publications where outcomes specific to a treatment-naive population could not be distinguished. Studies reporting outcomes such that results could not be obtained for each treatment arm individually were also excluded. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed through all phases in the study [14] (link).
Three researchers independently abstracted data from the final selection of studies into a structured Microsoft Access database and data were reconciled for accuracy. The Effective Public Health Practice Project Quality Assessment, a quality assessment tool, was used to assess selection bias, study design, confounders, blinding, data collection methods, and withdrawals and dropouts [15] (link).

Children with HIV infection were eligible for the study if they had not previously been exposed to antiretroviral agents (except for those used to prevent mother-to-child transmission of HIV), if they required treatment according to WHO criteria, and if their baseline level of plasma HIV type 1 (HIV-1) RNA was above 5000 copies per milliliter. Children (and their mothers) could not have had previous exposure to non-nucleoside reverse-transcriptase inhibitors (NNRTIs) such as nevirapine or efavirenz (hereinafter referred to as an absence of exposure to nevirapine).
The children were stratified by age (2 to <6, 6 to <12, or 12 to 36 months) and randomly assigned in equal numbers to either nevirapine or ritonavir-boosted lopinavir, combined with zidovudine and lamivudine. Nevirapine was initially given in a dose of 4 mg per kilogram of body weight once daily for 14 days, with a dose of 7 mg per kilogram twice daily thereafter (the dose approved by the Food and Drug Administration). An amendment to the protocol (September 4, 2007) increased the nevirapine dose to 160 to 200 mg per square meter of body-surface area (once daily for 14 days, then twice daily) in line with newly instituted WHO recommendations.
Children were enrolled at one site in India and at nine sites across sub-Saharan Africa (four in South Africa and one each in Zimbabwe, Zambia, Malawi, Uganda, and Tanzania). The study was approved by the ethics review committee at each site, the Ministries of Health (where appropriate), and the institutional review board at each partner institution in the United States. Each child’s parent or legal guardian provided written informed consent. Study visits and laboratory testing were conducted as previously described.1 (link)All the authors vouch for the completeness and accuracy of the data presented. The study was conducted in accordance with the protocol, available with the full text of this article at NEJM.org. The antirectroviral drugs used in this study were donated by Abbott, Boehringer Ingelheim, and GlaxoSmithKline. Representatives of these three pharmaceutical manufacturers participated in early discussions of the trial design but not in final design decisions or in trial implementation or analyses.

At 4 weeks of age, male wild type (WT; n = 17) and IL-10−/− mice (n = 40) were randomly assigned to either a placebo or combined antiretroviral therapy (cART) for 12 weeks ± 1 week. The chosen cART regimen using repurposed HIV nucleoside/nucleotide reverse transcriptase inhibitors and protease inhibitors had been evaluated for activity in antagonizing MMTV in vitro and demonstrated antiviral activity in vivo corresponding with improvement of inflammatory disease in prior studies [21 (link)]. Animals were fed ad libitum with cART added to the drinking water, freshly prepared every second day for 12 weeks, to achieve a daily dose of 1 mg emtricitabine and 1.5 mg tenofovir disoproxil fumarate nucleoside/nucleotide reverse transcriptase inhibitors as well as 4 mg lopinavir boosted with 1 mg ritonavir protease inhibitors, as described previously [21 (link)]. Control treatment group mice received ground placebo tablets in their drinking water. Water consumption was monitored daily and mouse weights measured weekly.

OATP1B1, OATP1B3, NTCP and vector control cell lines were cultured and subsequent transporter assays conducted as described above using the same transporter‐specific probe substrates and incubation times. For OATP1B1, the probe substrate was [3H]‐estradiol 17β‐D‐glucuronide (0.02 μM) incubated for 2 min, with rifamycin SV (100 μM) as positive control inhibitor. For IC50 determinations, the only difference to the method performed above was that the 15‐min pre‐incubation step contained a range of six concentrations of protease inhibitor drug, and subsequent incubations were conducted with the same six concentration levels of drug rather than with a single concentration. All four protease inhibitor drugs were studied against OATP1B1 using pre‐incubation/incubation concentrations of either 0.1, 0.3, 1, 3, 10 and 30 μM for atazanavir and darunavir, or 0.03, 0.1, 0.3, 1, 3 and 10 μM for lopinavir and ritonavir. Based upon the results determined from the inhibition screen, only atazanavir and lopinavir were studied against OATP1B3 or NTCP using concentrations of 0.1, 0.3, 1, 3, 10 and 30 μM and 0.03, 0.1, 0.3, 1, 3 and 10 μM, or 0.3, 1, 3, 10, 30 and 50 μM and 0.1, 0.3, 1, 3, 10 and 20 μM, respectively.
For each drug, determined percentage (vehicle) control transport activity was plotted against nominal inhibitor concentration and fitted using SigmaPlot 12.5 (Systat Software Inc., Chicago, IL; four parameter logistic equation) to determine the concentration that produces half‐maximal inhibition of probe substrate transport (IC50; equivalent to Ki assuming competitive inhibition as probe substrate concentration in the assay is at least 10‐times lower than its Km).
