Treatment: Drugs - DOR/ISL
Treatment: Drugs - BIC/FTC/TAF
Treatment: Drugs - Placebo to BIC/FTC/TAF
Treatment: Drugs - Placebo to DOR/ISL

Experimental: DOR/ISL and Placebo to BIC/FTC/TAF - Participants will receive DOR/ISL 100 mg/0.25 mg and Placebo to BIC/FTC/TAF once daily (QD) orally from day 1 to week 144. After week 144, eligible participants may continue on DOR/ISL and continue study treatment until week 240 or to when DOR/ISL becomes commercially accessible (whichever comes first).

Active comparator: BIC/FTC/TAF and Placebo to DOR/ISL - Participants will receive BIC/FTC/TAF 50 mg/200 mg/25 mg and Placebo to DOR/ISL once daily (QD) orally from day 1 to week 144. After week 144, eligible participants may switch to DOR/ISL and continue study treatment until week 240 or to when DOR/ISL becomes commercially accessible (whichever comes first).
