Study Arms:
- Part A (Renal Impairment): Moderate or Severe Renal Impairment (Type: EXPERIMENTAL): Participants with chronic hepatitis B (CHB) and moderate or severe renal impairment who were virologically suppressed and taking tenofovir disoproxil fumarate (TDF), a TDF-containing anti-hepatitis B virus (HBV) regimen, or other oral antivirals (OAVs), will switch to tenofovir alafenamide (TAF) and receive TAF 25 milligram (mg) tablet once daily orally for 96 weeks.
- Part A (Renal Impairment): End Stage Renal Disease (Type: EXPERIMENTAL): Participants with CHB and end stage renal disease who were virologically suppressed and taking TDF, a TDF-containing anti-HBV regimen, or OAVs, will switch to TAF and receive TAF 25 mg tablet once daily orally for 96 weeks.
- Part B: Hepatic Impairment (Type: EXPERIMENTAL): Participants with CHB and moderate or severe hepatic impairment who were virologically suppressed and taking TDF, a TDF-containing anti-HBV regimen, or OAVs, will switch to TAF and receive TAF 25 mg tablet once daily orally for 96 weeks.
