In Part 2b, a dose selected from Part 2a will be administered to participants randomized into 4 cohorts where they will be dosed weekly (QW) or bi-weekly (Q2W).
Each of the cohorts in Part 2b will include participants receiving active drug or placebo in a 3:1 ratio.

Measure Description |
Time Frame |
---|---|---|
Percentage of Participants With Adverse Events (AEs) and AEs of Special Interest
Time Frame: Up to day 113
|
An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. AEs of Special Interest were defined as: i.) elevated ALT/AST in combination with elevated bilirubin/clinical jaundice, ii.) suspected transmission of infectious agent by the study drug, iii.) severe injection site reactions, iv.) ALT elevation ≥10x ULN, v.) creatinine elevation ≥1.5x ULN or ≥50% from baseline. |
Up to day 113

Percentage of Participants With Laboratory Abnormalities Based on Hematology, Blood Chemistry, Coagulation, and Urinalysis Test Results - Part 1
Time Frame: Screening, Days -1, 2, 8, 15, 29, 85
|
Marked reference range has been predefined for each laboratory parameter.
The marked reference range is broader than the standard reference range.
Values falling outside the marked reference range that also represent a defined change from baseline will be considered marked laboratory abnormalities (i.e., potentially clinically relevant).
If a baseline value is not available for a study subject, the midpoint of the standard reference range will be used as the study participant baseline value for the purposes of determining marked laboratory abnormalities.
