What is "cabotegravir"

Cabotegravir (USAN and INN) (also known as S/GSK1265744 or GSK744) is an investigational new drug under development for the treatment of HIV infection. It is an integrase inhibitor, with a carbamoyl pyridone structure similar to dolutegravir. In investigational studies, the agent has been packaged into nanoparticles (GSK744LAP) conferring an exceptionally long half-life of 21–50 days following a single dose. In theory, this would make possible suppression of HIV with dosing as infrequently as once every three months.
