Outcome Measures
Primary Outcomes (8)
Change From Baseline in Plasma Human Immunodeficiency Virus (HIV) Ribonucleic Acid (RNA) on Day 10 (Cohort I)
Mean change from baseline on Day 10 in plasma Human Immunodeficiency Virus (HIV) Ribonucleic acid (RNA) (copies/mL)
Baseline and Day 10
Number of Patients With Clinical Adverse Experiences (CAEs) and Number of Patients With Serious CAEs at Day 10 (Cohort I)
An adverse experience (AE) is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR'S product, whether or not considered related to the use of the product. Serious CAEs are any AEs occurring at any dose that; Results in death; or Is life threatening; or Results in a persistent or significant disability/incapacity; or Results in or prolongs an existing inpatient hospitalization; or Is a congenital anomaly/birth defect; or Is a cancer; or Is an overdose.
10 days
Number of Participants With HIV RNA Levels Below 400 Copies/mL at Week 24 (Cohort II)
Week 24
Number of Patients With Clinical Adverse Experiences (CAEs)
An adverse experience (AE) is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR'S product, whether or not considered related to the use of the product.
48 weeks
Number of Patients With Serious CAEs (Cohort I and II Combined)
Serious CAEs are any AEs occurring at any dose that; Results in death; or Is life threatening; or Results in a persistent or significant disability/incapacity; or Results in or prolongs an existing inpatient hospitalization; or Is a congenital anomaly/birth defect; or Is a cancer; or Is an overdose
48 weeks
Number of Patients With Serious CAEs and Non-serious CAEs at Week 144
An adverse experience (AE) is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR'S product, whether or not considered related to the use of the product An adverse experience (AE) is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR'S product, whether or not considered related to the use of the product
144 Weeks
Number of Participants With Clinical Adverse Experiences (AEs)and Serious Adverse Experiences (SAEs)
An AE was defined as any unfavorable \& unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study drug, whether or not considered related to its use. Any worsening of a preexisting condition which was temporally associated with the use of the study drug, was also an AE. A SAE was any AE that resulted in death, was life threatening, resulted in a persistent or significant disability/incapacity, resulted in or prolonged an existing inpatient hospitalization, was a congenital anomaly/birth defect, was cancer, or was an overdose.
Week 240
Number of Participants With HIV RNA (Human Immunodeficiency Virus Ribonucleic Acid) Levels Below 50 Copies/mL at Week 240
HIV RNA levels were determined by AMPLICOR HIV-1 Monitorâ„¢ UltraSensitive Assay.
