Groups2
Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Ravulizumab | Participants received weight-based dosages of ravulizumab for 26 weeks during the Initial Treatment Period. Participants received a loading dose of ravulizumab intravenously on Day 1, followed by maintenance dosing on Day 15 and once every 8 weeks thereafter. | 4 | 9 | OG000 |
| Group 2 | Placebo | Participants received weight-based dosages of placebo matched to ravulizumab for 26 weeks during the Initial Treatment Period. Participants received a loading dose of placebo matched to ravulizumab intravenously on Day 1, followed by maintenance dosing on Day 15 and once every 8 weeks thereafter. | 4 | 7 | OG001 |

Outcome
- Type
- SECONDARY
- Title
- Number of Participants With Renal Response at Week 26
- Description
Renal response is improvement in eGFR of \>= 30% compared to baseline. If a participant is on dialysis ≤5 days prior to the date of eGFR assessment, the eGFR will be set to 10 milliliter/minute/1.73 meter square (mL/min/1.73 m\^2) for that assessment. If a participant is on dialysis during the entire 26 week randomized Treatment Period, or through early discontinuation of study drug, then the change in eGFR was not calculated.
- Time frame
- Week 26
- Population
The Modified Intent-to-Treat Analysis Set included all randomized participants, excluding participants who enrolled prior to availability of ST-HUS and ADAMTS13 central laboratory results and were subsequently found to be ineligible after randomization.
