Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | HyQvia New Starters | Participants who were treated with non-HyQvia treatment by time of enrollment were enrolled in Epoch 1 (ramp-up) and treated with HyQvia SC with a dose or interval ramp-up period of up to 6 weeks. HyQvia dose was planned to be equivalent to 100% (±5%) of pre-study treatment. Dosage Frequency was one treatment interval of one week, then one treatment interval of two weeks, then one treatment interval of three weeks (for participants in whom treatment was expected to be every four weeks). The ramp-up period was followed by Epoch 2 (no ramp-up) with HyQvia SC treatment at every 3 or 4 weeks, depending on the participant's previous dosing schedule and the discretion of the investigator and participant, for up to 20 months. | 2 | 23 | EG000 |
| Group 2 | HyQvia Pre-treated | Participants already treated with HYQVIA by the time of enrollment were directly enrolled in Epoch 2 and treated with HyQvia SC at every 3 or 4 weeks for up to 20 months. HyQvia dose was planned to be equivalent to 100% (±5%) of pre-study treatment with a dosage frequency of once every three or four weeks, based on the participants previous dosing schedule and the discretion of the investigator and participant. | 5 | 19 | EG001 |
