Primary	Number of Participants With Grade 3 and Grade 4 Adverse Events (AEs) Through Day 35	An AE is any untoward medical occurrence that occurs in a participant. An AE can be any unfavorable and unintended sign (including abnormal laboratory findings), symptom, or disease temporally associated with treatment, whether considered related to the product. AEs may include the onset of a new illness or undesirable medical condition or the exacerbation of pre-existing medical conditions. AE severity was graded as Grade 3 (Severe) and Grade 4 (Potentially Life-threatening) per the specific toxicity grading by the Division of Acquired Immunodeficiency Syndrome (DAIDS) AE Grading Table.	Up to Day 35
Primary	Number of Participants With AEs Resulting in Study Intervention Discontinuation Through Day 35	An AE is any untoward medical occurrence that occurs in a participant. An AE can be any unfavorable and unintended sign (including abnormal laboratory findings), symptom, or disease temporally associated with treatment, whether considered related to the product. AEs may include the onset of new illness or undesirable medical condition or the exacerbation of pre-existing medical conditions.	Up to Day 35
Primary	Number of Participants With Serious Adverse Events Through Day 35	A serious AE is any untoward medical occurrence or effect, that, at any dose: results in death; is life-threatening; requires hospitalization or prolongation of existing hospitalization; results in persistent or significant disability or incapacity; is an important medical event that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the participant or may require intervention to prevent one of the other outcomes.	Up to Day 35
Primary	Number of Participants Who Progressed to Moderate or Severe Disease or Higher Based on the Gates MRI Ordinal Scale Through Day 28	Participants who progressed to a moderate or severe disease category or higher (Bill & Melinda Gates Medical Research Institute [Gates MRI] ordinal scale =3) are reported.
