Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants With HIV-1 RNA < 50 Copies/mL at Week 24 as Defined by the Food and Drug Administration (FDA)-Defined Snapshot Algorithm	The percentage of participants with HIV-1 RNA < 50 copies/mL at Week 24 was analyzed using the snapshot algorithm, which defined a participant's virologic response status using only the viral load at the predefined timepoint within an allowed window of time, along with study drug discontinuation status.	Week 24
Secondary	Percentage of Participants Experiencing Adverse Events (AEs) Through Week 24	An AE was any untoward medical occurrence in a clinical study participant administered a medicinal product, which did not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and/or unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. AEs may also included pre- or post-treatment complications that occurred as a result of protocol specified procedures, lack of efficacy, overdose, drug abuse/misuse reports, or occupational exposure. Preexisting events that increased in severity or changed in nature during or as a consequence of participation in the clinical study were also considered AEs.	First dose date up to Week 24
Secondary	Percentage of Participants Experiencing AEs Through Week 48	An AE was any untoward medical occurrence in a clinical study participant administered a medicinal product, which did not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and/or unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. AEs may also included pre- or post-treatment complications that occurred as a result of protocol specified procedures, lack of efficacy, overdose, drug abuse/misuse reports, or occupational exposure. Preexisting events that increased in severity or changed in nature during or as a consequence of participation in the clinical study were also considered AEs.	First dose date Up to Week 48
Secondary	Percentage of Participants Experiencing AEs Through Week 72	An AE was any untoward medical occurrence in a clinical study participant administered a medicinal product, which did not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and/or unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. AEs may also included pre- or post-treatment complications that occurred as a result of protocol specified procedures, lack of efficacy, overdose, drug abuse/misuse reports, or occupational exposure. Preexisting events that increased in severity or changed in nature during or as a consequence of participation in the clinical study were also considered AEs.	First dose date Up to Week 72
Secondary	Percentage of Participants Experiencing AEs Through Week 96	An AE was any untoward medical occurrence in a clinical study participant administered a medicinal product, which did not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and/or unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. AEs may also included pre- or post-treatment complications that occurred as a result of protocol specified procedures, lack of efficacy, overdose, drug abuse/misuse reports, or occupational exposure. Preexisting events that increased in severity or changed in nature during or as a consequence of participation in the clinical study were also considered AEs.	First dose date Up to Week 96
