Primary | Percentage of participants reporting AEs and related AEs | 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. | From first study dose administration (Day 1) up to study end (Week 52 post last dose) | |
Primary | Percentage of participants with AEs by severity | Severity of Adverse Events 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. | From first dose administration (Day 1) up to study end (Week 52 post last dose) | |
