Plasma samples were collected for the quantitative analysis of plasma HIV-1 RNA. The maximum change from baseline was calculated by determining the largest change from baseline value across all assessment timepoints during the monotherapy period. This is identified by subtracting the lowest post-dose visit value up to Day 10 (inclusive) from the baseline value. The baseline was defined as the most recent pre-dose assessment with a valid, non-missing value, including measurements from any unscheduled visits.
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. Related AE = AE assessed by the investigator as related to the study drug.
Severity of AEs will be assessed using Division of AIDS Table for Grading the Severity of Adult Adverse Events (DAIDS). DAIDS grading scale is used to grade the toxicity associated with injection site reactions (ISR) including injection site pain (or tenderness), erythema (or redness), induration (or swelling), and pruritis. The toxicity level is graded from Grade 1 (lowest toxicity) to 4 (highest toxicity). Higher grade indicates higher toxicity.
The liver panel laboratory parameters are assessed after the administration of long-acting injectable (LAI) VH4524184.
The liver panel laboratory parameters are assessed after the administration of LAI VH4524184.
The liver panel laboratory parameters are assessed after the administration of LAI VH4524184.
Assessed ISRs are pain, tenderness, infections, erythema, swelling, induration, or nodules (granulomas or cysts). Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, and Grade 4 = potentially life threatening.
Blood samples will be collected at indicated timepoint for plasma EE and NEA PK analysis.
