  • For female participants of childbearing potential: an agreement to remain abstinent or use contraception.
  • Female participants of childbearing potential must have a negative serum pregnancy test result within 7 days prior to initiation of crovalimab.
  • Participants with a prior kidney transplant are eligible if they have a known history of complement-mediated aHUS prior to the kidney transplant.

Assessed by the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Questionnaire.

The FACIT-Fatigue (version 4) assesses self-reported fatigue and its impact upon daily activities and function. It consists of 13 items that assess fatigue using a 7-day recall period. Items are scored on a 0 (not at all) to 4 (very much) response scale. Relevant items are reverse scored and all items are summed to create total scores ranging from 0 \[worse score\] to 52 \[better score\].
