Hemolytic Paroxysmal Nocturnal Hemoglobinuria, Eculizumab, PNH
Brief summary
The objective of this study was to assess the long-term safety and efficacy of eculizumab in hemolytic PNH patients who completed the 4-week screening and 12-week treatment period of the C07-001 study. In addition, pharmacokinetic and pharmacodynamic assessments of eculizumab were conducted.
Interventions
Each vial contains 30 mL of 10 mg/mL eculizumab; dose of 900 mg intravenous every 14 days.

| Change From Baseline in FACIT-Fatigue Scale Total Score | 52 weeks (includes 12 weeks of eculizumab treatment in the parent study and 40 weeks in the extension study) | The FACIT-Fatigue scale, Version 4.0, is a collection of quality of life questionnaires pertaining to the management of fatigue symptoms due to a chronic illness. The FACIT-Fatigue is a 13-item questionnaire that assesses self-reported fatigue and its impact upon daily activities and function over the preceding 7 days. Patients score each item on a 5-point scale: 0 (Not at all) to 4 (Very much). Total scores range from 0 to 52, with higher score indicating better quality of life. |
