Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Adverse Events (AEs) | Up to 18 months | An AE is defined as any untoward medical occurrence in a participant including unfavorable and unintended signs, symptoms or disease temporally associated with the use of a medicinal product and which does not necessarily have to have a causal relationship to this treatment. AEs include illnesses with onset during the trial, or exacerbations of pre-existing illnesses. Exacerbation of pre-existing illness is defined as a significant increase in the severity of the illness as compared to the start of the trial and was considered when a participant requires new or additional treatment for that illness. Lack of or insufficient clinical response or efficacy was not recorded as an AE. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Anti-drug Antibody (ADA) | Up to 18 months | Number of participants with ADA = Post-baseline positive (in Baseline negative group) + treatment-boosted ADA positive (in Baseline positive group) / participants with a Baseline and at least one post-baseline sample. For participants whose ADA status is positive at Baseline, a post-baseline titer value that is \>= 4 times higher than the Baseline is considered treatment-boosted ADA. |
| Plasma Concentrations of ACP | Months 1, 2, 4, 7, 13, and 18 | Concentrations below the lower limit of quantification (3.36 ng/mL) are set to zero for calculation of summary statistics. |
