Any adverse event not specifically listed in the WHO Toxicity Grading Scale was assessed according to the following levels of severity: Grade 1 is mild; Grade 2 is moderate; Grade 3 is severe; and Grade 4 is life-threatening. Investigator text for adverse events were encoded using the Medical Dictionary for Regulatory Activities (MedDRA) version 21.1. After informed consent had been obtained but prior to initiation of study drug, only serious adverse events (SAEs) caused by a protocol-mandated intervention were to have been reported. After initiation of study drug, all adverse events, regardless of relationship to study drug, were to have been reported until the participant completed his last study visit. After this period, any SAEs believed to be related to prior study drug treatment were to be reported.

'Total ADA Positive' is the sum of all participants who tested positive for ADA in the 2 following categories: 'ADA Positive (Treatment Induced)', those who were ADA negative at baseline and tested positive for ADA following study drug administration; and 'ADA Positive (Treatment Boosted)', those who were pre-dose ADA positive and had post-baseline samples with a titer that was at least 4-fold greater compared to the baseline measurement.

Note that samples from all participants were analyzed for each laboratory parameter. Values falling above or below the Roche predefined standard reference range were laboratory abnormalities labelled accordingly as 'high' or 'low'. Not every laboratory abnormality qualified as an adverse event; only if it was accompanied by clinical symptoms, resulted in a change in study treatment or in a medical intervention, or was clinically significant in the investigator's judgment.

    Time frame: From screening to study completion (20 weeks)

    The original terms recorded by the investigator for concomitant medications were standardized by the sponsor by assigning preferred terms. The duration of treatment with the concomitant medications ranged from 1 day to 5 days. Except for 1 participant who was treated during the in-clinic period (Days -1 to 4), all other concomitant medications were recorded during the ambulatory period (Days 6 to 113).
