Journal ArticleDOI
Dolutegravir versus raltegravir in antiretroviral-experienced, integrase-inhibitor-naive adults with HIV: week 48 results from the randomised, double-blind, non-inferiority SAILING study.
Pedro Cahn,Anton Pozniak,Horacio Mingrone,Andrey Shuldyakov,Carlos Brites,Jaime Andrade-Villanueva,Gary Richmond,Carlos Beltran Buendia,Jan Fourie,Moti Ramgopal,Debbie Hagins,Franco Felizarta,José Valdez Madruga,Tania Reuter,Tamara Newman,Catherine B. Small,John Lombaard,Beatriz Grinsztejn,David Dorey,Mark R. Underwood,Sandy Griffith,Sherene Min +21 more
TL;DR: Once-daily dolutegravir, in combination with up to two other antiretroviral drugs, is well tolerated with greater virological effect compared with twice-daily raltegravIR in this treatment-experienced patient group.
Journal ArticleDOI
In Vitro Antiretroviral Properties of S/GSK1349572, a Next-Generation HIV Integrase Inhibitor
Masanori Kobayashi,Tomokazu Yoshinaga,Takahiro Seki,Chiaki Wakasa-Morimoto,Kevin W. Brown,Robert G. Ferris,Scott A. Foster,Richard J. Hazen,Shigeru Miki,Akemi Suyama-Kagitani,Shinobu Kawauchi-Miki,Teruhiko Taishi,Takashi Kawasuji,Brian A. Johns,Mark R. Underwood,Edward P. Garvey,Akihiko Sato,Tamio Fujiwara +17 more
TL;DR: Findings demonstrate that S/GSK1349572 would be classified as a next-generation drug in the integrase inhibitor class, with a resistance profile markedly different from that of first-generation integrase inhibitors.
Journal ArticleDOI
Efficacy, safety, and tolerability of dolutegravir-rilpivirine for the maintenance of virological suppression in adults with HIV-1: phase 3, randomised, non-inferiority SWORD-1 and SWORD-2 studies
Josep M. Llibre,Chien-Ching Hung,Cynthia Brinson,Francesco Castelli,Pierre-Marie Girard,Lesley P Kahl,Elizabeth A. Blair,Kostas Angelis,Brian Wynne,Kati Vandermeulen,Mark R. Underwood,Kim Smith,Martin Gartland,Michael Aboud +13 more
TL;DR: Dolutegravir-rilpivirine was non-inferior to CAR over 48 weeks in participants with HIV suppression and showed a safety profile consistent with its components, which supports the use of this two-drug regimen to maintain HIV suppression.
Journal ArticleDOI
Dolutegravir (S/GSK1349572) Exhibits Significantly Slower Dissociation than Raltegravir and Elvitegravir from Wild-Type and Integrase Inhibitor-Resistant HIV-1 Integrase-DNA Complexes
Kendra E. Hightower,Ruolan Wang,Felix Deanda,Brian A. Johns,Kurt Weaver,Yingnian Shen,Ginger H. Tomberlin,H. Luke Carter,Timothy Broderick,Scott D Sigethy,Takahiro Seki,Masanori Kobayashi,Mark R. Underwood +12 more
TL;DR: The dissociation rates of these INIs with integrase (IN)-DNA complexes containing a broad panel of IN proteins, including IN substitutions corresponding to signature RAL and ELV resistance mutations are determined, consistent with the potential for DTG to have a higher genetic barrier to resistance and evidence that the INI off-rate may be an important component of the mechanism of INI resistance.
Journal ArticleDOI
Characterization of the R263K Mutation in HIV-1 Integrase That Confers Low-Level Resistance to the Second-Generation Integrase Strand Transfer Inhibitor Dolutegravir
Peter K. Quashie,Thibault Mesplède,Ying-Shan Han,Maureen Oliveira,Diane N. Singhroy,Diane N. Singhroy,Tamio Fujiwara,Mark R. Underwood,Mark A. Wainberg,Mark A. Wainberg +9 more
TL;DR: In vitro selection experiments with DTG using viruses of subtypes B, C, and A/G and showed that the most common mutation to emerge was R263K, which does confer low-level resistance to DTG and decreased integration in cell culture without altering reverse transcription.
