1C We recommend patients stopping a PI-containing regimen stop all drugs simultaneously and no replacement is required. 1C 6.3.2 We recommend in patients
on suppressive ART regimens, consideration phosphatase inhibitor library is given to differences in side effect profile, drug–drug interaction (DDIs) and drug resistance patterns before switching any ARV component. GPP We recommend, in patients with previous NRTI resistance mutations, against switching a PI/r to either an NNRTI or an INI as the third agent. 1B 6.3.3 We recommend continuing standard combination ART as the maintenance strategy in virologically suppressed patients. There are insufficient data to recommend PI/r monotherapy in this clinical situation. 1C 6.4 We recommend against treatment interruption or intermittent therapy in patients stable on a virally suppressive ART regimen. 1A 7.2 In patients on ART: A single VL 50–400 copies/mL preceded and followed by an undetectable VL is usually not a cause for clinical concern. GPP
We recommend a single VL >400 copies/mL is investigated further, as it is indicative of virological failure. 1C We recommend in the context of repeated viral blips, resistance testing is attempted. 1D 7.3 We recommend patients experiencing virological failure on first-line ART with wild-type (WT) virus at baseline and without emergent resistance mutations at failure switch to a PI/r-based combination Selleck Dabrafenib ART regimen. 1C We recommend patients experiencing virological
failure on first-line ART with WT virus at baseline and limited emergent resistance mutations (including two-class NRTI/NNRTI) at failure switch to a new PI/r-based regimen with the addition of at least one, preferably two, active drugs. 1C We recommend patients experiencing virological failure on first-line PI/r plus two-NRTI-based regimen, with major protease mutations, switch to a new active PI/r with the addition of at least one, preferably two, active agents of which one has a novel mechanism of action. 1C We recommend against switching a PI/r to RAL or an NNRTI as the third agent in patients with historical or existing reverse transcriptase (RT) mutations associated with NRTI resistance or past virological failure on NRTIs. 1B 7.4 We recommend patients with persistent viraemia and with limited options to construct a fully suppressive regimen are discussed/referred Liothyronine Sodium for expert advice (or through virtual clinic referral). GPP We recommend patients with triple-class resistance switch to a new ART regimen containing at least two and preferably three fully active agents with at least one active PI/r such as DRV/r or tipranavir/ritonavir (TPV/r) and one agent with a novel mechanism (CCR5 receptor antagonist or integrase/fusion inhibitor) with etravirine (ETV) an option based on viral susceptibility. 1C 7.5 We recommend accessing newer agents through research trials, expanded access and named patient programmes.
