Outcome
Type	Measure	Description	Time frame
Primary	Percentage of Participants with One or More Adverse Event (AE)	An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The percentage of participants who experience an AE through Week 102 will be presented.	Up to 102 Weeks
Primary	Percentage of participants who Discontinue Study Intervention Due to an AE	An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The percentage of participants who discontinue study intervention due to an AE through Week 96 will be presented.	Up to 96 Weeks
Secondary	Percentage of Participants with HIV-1 Ribonucleic Acid (RNA) =50 copies/mL at Week 96	The percentage of participants with HIV-1 RNA =50 copies/mL at Week 96 will be reported.	Week 96
Secondary	Percentage of Participants with HIV-1 RNA <50 copies/mL at Week 96	The percentage of participants with HIV-1 RNA <50 copies/mL at Week 96 will be reported.	Week 96
Secondary	Percentage of Participants with HIV-1 RNA =200 copies/mL at Week 96	The percentage of participants with HIV-1 RNA =200 copies/mL at Week 96 will be reported	Week 96
Secondary	Percentage of Participants with Evidence of Viral Drug Resistance-Associated Substitutions	Viral drug resistance is defined as participants with HIV-1 RNA =400 copies/mL and/or genotypic or phenotypic data showing evidence of resistance to the study intervention. The percentage of participants who demonstrate drug resistance through Week 96 will be presented.	Up to Week 96
