Background: Virological and Immunological Studies in CONtrollers after Treatment Interruption (VISCONTI) are required to understand the benefits of an early treatment at acute HIV-1 infection on the HIV reservoir. We studied the distribution, magnitude and inducibility of the HIV reservoir in VISCONTI patients.
Methods: The prospective VISCONTI study included twelve patients controlling HIV for a median of 76[IQR:67.5-84.5] months after interruption of a 3[IQR:1.7-5.9] years long HAART initiated within 10 weeks post-infection. Circulating resting CD25-CD69-HLADR- CD4+T cell subsets were sorted as naive (TN), central-memory (TCM), transitional-memory (TTM) and effector-memory cells (TEM) for further cell-associated HIV-DNA quantification by ultrasensitive real-time-PCR, and viral inducibility by culture with anti-CD3/anti-CD28/IL-2/IL-7. Reservoir distribution was compared to the one observed in 8 untreated Elite-Controllers for whom 90% of HIV-RNA measures was undetectable (below 200 copies) over 12[9-14] years.
Results: In the VISCONTI group, activated CD4+T cells had significantly higher HIV-DNA levels than resting ones (median 2.7[IQR:2.4-3.4] and 2[IQR:1.8-2.5] log copies/million cells, p=0.005). HIV-DNA was detected in all subsets from all patients except for 8 out of 12 TN-sorted cells, which were 10 fold less infected than all memory subsets (median TN:1.5[IQR:1.2-1.6], TCM:2.5[IQR:1.8-2.9], TTM:2.6[IQR:2.2-2.8] and TEM:2.4[IQR:2-2.8] log copies/million cells, p< 0.007). TTM was the major subset contributing to 56% of this reservoir. The same HIV reservoir characteristics were observed in Elite-Controllers in term of magnitude and distribution, except that both TCM and TTM equally contributed to the Elite-Controllers HIV reservoir. The VISCONTI HIV reservoir was inducible after TCR-stimulation in all sorted memory subsets from all patients, except in TN where no virus was recovered in 6 out of 8 patients.
Conclusions: In VISCONTI patients, treatment initiated at primary HIV-1 infection leads, after treatment interruption, to a low -but inducible- durable HIV reservoir distributed mainly in short-lived memory CD4+T cells that mimicks the natural distribution observed in Elite-Controllers.

GSK is Exploring a Once a Month Injectable HIV Treatment Regimen
Presented at the International AIDS Conference in Washington this weekPharmacokinetics, Safety and Tolerability of the HIV Integrase Inhibitor S/GSK1265744 Long Acting Parenteral Nanosuspension Following Single Dose Administration to Healthy Adults
Discussion-- S/GSK1265744 long acting parenteral administration prolonged plasma levels (apparent t1/2of 2150days; Figure 4) compared with oral administration (oral t1/2of 30-40 hours)-- AUC(0-∞)appeared to increase in a dose-proportional manner; Cmax increased greater than proportional to dose following 800 mg IM, suggesting the rate of absorption was higher for this dose (Table 2)-- 800 mg IM achieved a mean S/GSK1265744 Cday 1021-fold above PA-IC90; this exposure is comparable to exposure observed with 30 mg oral, once-daily dosing, which produced a -2.5 log10decrease in HIV RNA following 10 days of monotherapy in HIV-infected subjects. Mean Cday28following 800 mg IM was 14-fold above PAIC90, making this a viable loading dose for S/GSK1265744 LAP-- Modeling and simulation (not shown) suggest S/GSK1265744 LAP 200-400 mg monthly is an appropriate maintenance dose for HIV treatment
ConclusionsS/GSK1265744 LAP single dose IM or SC 100-800 mg was safe and generally well tolerated in healthy adult subjects. Both IM and SC routes of administration will be evaluated in repeat-dose clinical trialsSingle SC or IM doses of the long-acting formulation yielded sustained S/GSK1265744 plasma concentrations previously shown to produce robust antiviral activity as oral monotherapy and suggest monthly to quarterly dosing intervals using clinically practical dose volumesStudy results support continued development; S/GSK1265744 is under evaluation for both HIV prevention as pre-exposure prophylaxis as well as HIV therapy with a partner antiretroviral agent, rilpivirine (TMC278-LA)AbstractBackground: S/GSK1265744, an HIV integrase inhibitor with proven antiviral activity following oral monotherapy, is under development as a long-acting parenteral (LAP) depot formulation. Antiretrovirals dosed monthly to quarterly may provide clinical utility for HIV treatment and prevention. This study evaluated pharmacokinetics (PK), safety, and tolerability of single S/GSK1265744 LAP doses in healthy adults.Methods: This was a phase I, randomized, double-blind, placebo-controlled, dose escalation study. S/GSK1265744 200 mg/mL nanosuspension was administered by intramuscular (IM) gluteal injection (100 mg, 200 mg, 400 mg, 800 mg [400 mg x2]) or subcutaneous (SC) abdominal injection (100 mg, 200 mg, 400 mg [200 mg x2]) to cohorts of eight (6 active/2 placebo) subjects. Safety and PK were assessed prior to dose escalation and continued until plasma S/GSK1265744 was <0.1 μg/mL by LC/MS/MS; PK parameters were determined by noncompartmental methods.Results: 25 females and 31 males were dosed; S/GSK1265744 LAP was generally well tolerated with mild-moderate, self-limited injection site reactions (ISR) reported as the most common adverse event (AE); ISR erythema and nodules were more frequent following SC dosing. Systemic safety was good with no drug-related serious AEs or grade 3-4 AEs. S/GSK1265744 was detected in plasma up to 48 weeks and exhibited absorption-limited kinetics; mean apparent terminal phase t1/2ranged 2150days vs. 40 h following oral dosing. S/GSK1265744 AUC(0-∞) appeared to increase proportionally to dose. Split dosing increased the apparent absorption rate. Mean S/GSK1265744 Cday 10 following 800 mg IM was similar to geometric mean Cτ,ss of 3.28μg/mL associated with -2.5 log10mean change in plasma HIV RNA following 10 days of 30 mg PO QD monotherapy.Conclusions: S/GSK1265744 LAP single dose IM or SC 100-800 mg was safe and generally well tolerated. Achievement of sustained plasma concentrations previously shown to produce >2.5 log10mean reduction of HIV RNA as monotherapy suggests S/GSK1265744 LAP may exhibit prolonged antiviral activity at clinically practical doses and supports continued development.S/GSK1265744 is an integrase strand transfer inhibitor in development as both an oral formulation and LAP injection. The compound has attributes that enable formulation and delivery as a nanosuspension for injection:-- High potency: deliver monthly or longer dose in clinically practical volume-- Low aqueous solubility and correct particle size to control release kinetics-- Low metabolic clearance: reduced drug input requirement-- Formulation prerequisites: withstand nanomilling forces, stability in formulation with excipients and stabilizers, a sterile productPrior clinical studies have demonstrated S/GSK1265744 oral monotherapy produces a vigorous antiviral effect in HIV-infected subjects at 5 or 30 mg once daily for 10 days (Figure 1). In vitro resistance studies suggest a favorable profile. The current study was undertaken to evaluate the safety and PK of single IM or SC doses of S/GSK1265744 LAP formulation in healthy adult subjects
