- Three of the subjects discontinued due to hypersensitivity reactions3
- One hypersensitivity event was considered related to the study drug and led to discontinuation3
- No discontinuations due to injection site reactions, and most injection site reactions resolved within 1 hour (70.2%) or 1 day (92.6%)3
