Switching from efavirenz/emtricitabine/tenofovir disoproxil fumarate (EFV/FTC/TDF) to the new bictegravir/ emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) regimen maintained high rates of virological suppression in adults who are living with HIV*, according to a study presented at AIDS 2020.

Monthly prophylaxis with the fixed-dose combination of naphthoquine-azithromycin (NQAZ) is well tolerated and confers significant protection against infection with Plasmodium parasites among individuals residing in malaria-endemic areas in Southeast Asia, as shown in the results of a phase III trial.
