Study design details

• Study design:
  This study will utilize existing data collected during 2 large Phase 3 clinical studies of FTC/TDF and F/TAF to conduct an indirect comparison of F/TAF (DISCOVER) and placebo treatment groups (iPrEX), using the common FTC/TDF treatment groups as negative controls.
• Main study objective:
  To compare weight change/trajectory distributions between F/TAF and placebo cohorts from the DISCOVER and iPrEx studies
• Setting:
  Both studies that will be used for this study recruited individuals not living with HIV, all of whom were adults aged at least 18 years, and with 1 or more behavioral risk factors for contracting HIV-1. ; All iPrEx study participants were born male, and were recruited from North and South America, South Africa, and Thailand. ; All DISCOVER study participants were born male or were TGW, and were recruited from North America, 8 European Union (EU) countries, and the UK. ; ;
