The RV254/SEARCH 010 study is an ongoing prospective, open-label study in Bangkok, Thailand (clinicaltrials.gov identification NCT00796146). The study was approved by the institutional review boards (IRBs) of Chulalongkorn University in Thailand and the Walter Reed Army Institute of Research in the United States. All subjects gave informed consent. Samples from subjects who had VCT for HIV at The Thai Red Cross Anonymous Clinic and at the Silom Community Clinic were screened in real-time by pooled NAT and sequential EIA according to published methods [13] (link). Thai subjects who fit the AHI laboratory criteria for Fiebig stages I to IV [14] (link) were enrolled (Figure 1) and had clinical and laboratory assessments at days 0, 2, 3, 5, 7, 10, weeks 2, 4, 8, 12, 16, 20, 24, and every 12 weeks thereafter up to 192 weeks. A checklist of ARS symptoms was employed by an HIV physician to assess all potential symptoms at the baseline and subsequent visits until all symptoms had resolved.
Laboratory assessments included CD4, HIV RNA, liver transaminases, creatinine, lipids and urinalysis. Plasma and peripheral blood mononuclear cells (PBMCs) were cryopreserved at all visits. Sampling of gut-associated lymphoid tissue (GALT) occurred at weeks 0 and 24 by sigmoidoscopy as an optional procedure (24 subjects at baseline and 13 subjects at week 24), and mucosal mononuclear cells (MMCs) were isolated from GALT.
Initiation of ART was voluntary and done as part of enrollment in an accompanying local protocol (clinicaltrials.gov identification NCT00796263), approved by the Chulalongkorn University IRB, and all subjects gave informed consent. Treatment was started on average 3 days (range 0–5 days) from enrollment. The regimen consisted of 5 antiretrovirals [tenofovir (TDF) 300 mg once daily, emtricitabine (FTC) 200 mg once daily, efavirenz (EFV) 600 mg once daily, raltegravir (RAL) 400 mg twice daily and maraviroc (MVC) 600 mg twice daily] for the first 24 weeks followed by simplification to 3 drugs with TDF, FTC and EFV. EFV was discontinued in subjects with intolerance or resistance, in which case dose adjustment of MVC to 300 mg twice daily was implemented. The first 10 subjects received the 5-drug regimen. Subsequently subjects were randomized 1∶1 (in a block of 30) to 5 drugs (MegaHAART) vs. 3 drugs (HAART with TDF, FTC, EFV) ART.

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).

In total, 26 animals were intravenously infected with 2.2x105 IU (1mL) of transfection produced SIVmac239M. All 26 animals were used to enumerate the number of detectable barcodes measured during primary infection. Of these 26 animals, two animals were followed for over 3 months to assess early viral replication kinetics (peak and set point viral load) of SIVmac239M. Four of the other infected animals began antiretroviral treatment beginning at day 6 post infection and continued for 82 days. Each animal received a combination antiretroviral therapy (cART) regimen comprising a co-formulated preparation containing the reverse transcriptase inhibitors tenofovir (TFV: (R)-9-(2-phosphonylmethoxypropyl) adenine (PMPA), 20 mg/kg) and emtricitabine (FTC; 50 mg/kg) administered by once-daily subcutaneous injection, plus raltegravir (RAL; 150-200mg) given orally twice daily. At the time of interruption from cART, three animals were infused at the day of cART interruption with autologous CD8+ T cells transduced with an anti-SIV Gag T-cell receptor (animals MK9 and KTM) or with an irrelevant receptor (animals KMB and KZ2) plus daily subcutaneous injections of IL-2 at 10,000 IU/kg for 10 days. The total number of infused cells ranged from 4.6 to 6.4x109 cells with <1% of the cells CD4+. In these animals, infused cells did not traffic to lymphoid or GI tissues and persistence of the cells was poor. Animal KTM died due to procedural complications at the time of cART interruption and was therefore excluded from subsequent analyses. In a separate cohort of 6 animals (study 2), therapy was initiated on day 4 post-infection with the same therapeutic regimen (TFV, FTC, RAL) described above with the addition of the protease inhibitor indinavir (IDV; 120mg BID) and ritonavir (RTV; 100mg BID) for the first 9 months. In study 2, cART treatment was continued for 305, 374, or 482 days, with two animals discontinuing therapy at each time point. The remaining 14 animals were used to enumerate the number of replicating clonotypes during primary infection.

Every six months the CPQA PT program offered prepared plasma samples containing pre-specified concentrations (unknown to CPLs) of up to 21 ARV analytes: abacavir (ABC), amprenavir (APV), atazanavir (ATV), darunavir (DRV), didanosine (DDI), efavirenz (EFV), emtricitabine (FTC), etravirine (ETR), indinavir (IDV), lamivudine (3TC), lopinavir (LPV), maraviroc (MVC), nelfinavir (NFV), nevirapine (NVP), raltegravir (RGV), ritonavir (RTV), saquinavir (SQV), stavudine (D4T), tenofovir (TFV), tipranavir (TPV), zidovudine (ZDV). In each round and for each ARV, 5 concentrations, spanning an expected therapeutic range of each ARV, as well as occasional concentrations below or above, were provided. Samples are prepared by an outside subcontractor and tested by the CPQA lab prior to distribution. PT samples were stored at −70 ± 15°C and then shipped on dry ice to participating laboratories with detailed instructions. Upon arrival, each laboratory confirmed sample integrity and indicated planned reporting of specific analytes. Results were reported either through an online Laboratory Data Management System (LDMS) or via a template which was then uploaded into the LDMS database. At the end of the submission period, a completeness evaluation was performed to confirm that all planned results were received; discrepancies were queried for resolution. To summarize the proficiency of individual labs, a pre-specified scoring algorithm was applied to the RCs (see next paragraph). The scoring algorithm reflects US Clinical Laboratory Improvement Act (CLIA) PT regulations[13 (link)]. After review and approval by the CPQA advisory board chair, a final report was sent to the participating laboratories (with laboratories de-identified) and key leadership (laboratories identified per network leader).
An individual RC is deemed Acceptable provided a concentration is present where expected, and the concentration is within 20% of the final target (FT)[14 (link)]. (If a concentration is reported as below the lower limit of quantification (BLQ), and the run lower limit was below 80%*FT, the concentration was labeled Unacceptable.) For a given prepared sample, if the number of labs reporting for that sample is large enough, the variability between CPLs is small enough (≤15%) and the percent deviation of the group mean (GM, determined after removal of outliers, if any)from the weighed-in value (WIV) is >5%, the FT is set to the GM. Otherwise, FT is set to the WIV. At the analyte level, a CPL’sperformance is deemed Satisfactory for the round provided at least 80% of RCs are Acceptable. If the CPL score is <80% for an analyte, the CPL submits a corrective action plan to reestablish accuracy; a root cause is requested. Finally, in accordance with CLIA rules, a lab is classified as successful for an analyte provided the round-specific score was Satisfactory in at least 2 of the last 3 rounds (including the current).

The
assay for the detection of HIV-1 integrase strand transfer (ST) inhibitors
was adapted from previously described methods.21 (link) A double-stranded biotinylated donor DNA, corresponding
to the HIV U5 viral DNA end, was added to the wells of Streptavidin-coated
96-well microtiter plates (R&D systems). Following a 1 h incubation
at r.t. and three wash steps with PBS, purified recombinant integrase
(1 μM) was assembled using DTT (dithiothreitol, 1 M) onto the
preprocessed donor DNA through incubation for 30 min at 22 °C.
After the wash step, the test compounds and a positive control inhibitor
(Raltegravir, Merck) were added into individual wells at a final concentration
of 10 μM. The microtiter plates were incubated for 30 min at
37 °C and washed. The strand transfer reaction was initiated
through the addition of FITC-labeled target dsDNA (5′-TGACCAAGGGCTAATTCACT-FITC-3′
and 5′-AGTGAATTAGCCCTTGGTCA-FITC-3′).
The plates were incubated for a period of 1 h at 37 °C followed
by washing as before. An AP (Alkaline S2 phosphatase)-conjugated anti-FITC
secondary antibody (Sigma) was added and the plates were washed. The
chromogenic substrate (BluePhos, KPL) was added to allow for photometric
measurement at 620 nm using a microplate reader (xMark, Biorad). Percentage
inhibition was calculated utilizing the formula: where A620(Comp) = Absorbance at 620 nm with compounds, A620_No_integrase_control = Absorbance at 620 nm containing no enzyme, and A620_No_inhibitor_control = Absorbance at 620 nm containing
no inhibitor. All inhibition values are the average of triplicate
experiments.

Chinese rhesus macaques (n = 18) that were confirmed to be seronegative for SIV, STLV-1 (simian T leukemia virus type 1), SRV-1 (simian type D retrovirus 1) and herpes B viruses were infected with SIVmac251 at 10 AID50 intravenously. Four days post-infection, 11 out of 18 animals were treated daily with tenofovir (TFV, 20 mg/kg; Gilead, Foster City, CA, USA) and emtricitabine (FTC, 40 mg/kg; Gilead) subcutaneously and raltegravir (RAL, 20 mg/kg; Merck, Kenilworth, NJ, USA) or dolutegravir (DTG, 5 mg/kg; ViiV, London, UK) and ritonavir (RTV, 20 mg/kg; Abbvie, North Chicago, IL, USA) orally, as previously described [48 (link)]. From the 11 ART-treated animals, n  =  3 received ART for the duration of the study until they had an undetectable plasma viral load and were euthanized at that time (SIV[+]/ART). n  =  8 had analytic therapy interruption (SIV[+]/ATI) at different time points after SIV suppression, and the animals were euthanized when they had a detectable plasma viral load. This duration varied from 10 to 28 days, with two animals requiring 159 and 161 days to rebound. Several animals (n = 7) did not receive ART (SIV[+]) and were euthanized 38 to 104 days post-infection. The animals were sacrificed at different time points post-infection, and the harvesting of the plasma, CSF and brain was performed immediately after the sacrifice [48 (link)].
