Description:
GSK1265744 (GSK744) is an integrase strand-transfer inhibitor that has been formulated as a long-acting (LA) injectable suitable for monthly to quarterly clinical administration. GSK744 LA was administered at two time points 4 weeks apart beginning 1 week before virus administration, and macaques were challenged weekly for 8 weeks. GSK744 LA, at plasma concentrations achievable with quarterly injections in humans, protected all animals against repeated low-dose challenges. In a second experiment, macaques were given GSK744 LA 1 week before virus administration and challenged repeatedly until infection occurred. Protection decreased over time and correlated with the plasma drug levels. With a quarterly dosing schedule in humans, our results suggest that GSK744 LA could potentially decrease adherence problems associated with daily preexposure prophylaxis (PrEP).〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4308974/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4308974/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andrews, Chasity D -- Spreen, William R -- Mohri, Hiroshi -- Moss, Lee -- Ford, Susan -- Gettie, Agegnehu -- Russell-Lodrigue, Kasi -- Bohm, Rudolf P -- Cheng-Mayer, Cecilia -- Hong, Zhi -- Markowitz, Martin -- Ho, David D -- 1DP1-DA033263/DA/NIDA NIH HHS/ -- 2P51-OD11104-52/OD/NIH HHS/ -- P51 OD011104/OD/NIH HHS/ -- R0-AI100724/AI/NIAID NIH HHS/ -- R01 AI100724/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1151-4. doi: 10.1126/science.1248707.
