Brief Summary:
A study to assess the safety and efficacy of eculizumab in Japanese patients with hemolytic PNH.

Condition or disease Intervention/treatment Phase
Paroxysmal Nocturnal Hemoglobinuria Biological: Eculizumab Phase 2

Detailed Description:
The objective of this study was to assess the safety and efficacy of eculizumab in Japanese patients with hemolytic PNH. In addition, the pharmacokinetics (PK) and pharmacodynamics (PD) of eculizumab in Japanese patients were assessed and compared to that of non-Japanese patients who had participated earlier studies of eculizumab treatment in hemolytic PNH.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 29 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase II Clinical Study of Eculizumab (h5G1.1-mAb) in Hemolytic Paroxysmal Nocturnal Hemoglobinuria (PNH) Patients
Study Start Date : November 2007
Primary Completion Date : June 2008
Study Completion Date : June 2008

Arm Intervention/treatment
Experimental: Eculizumab
Eculizumab intravenous infusions every week x 4 doses, then 900 mg 1 week later for 1 dose, then 900 mg every 2 weeks for 4 doses
Biological: Eculizumab
Other Name: Soliris

Primary Outcome Measures :
  1. Change From Baseline in Lactate Dehydrogenase [ Time Frame: Baseline, Week 12 ]

Secondary Outcome Measures :
  1. Change From Baseline in Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale Total Score [ Time Frame: Baseline, Week 12 ]
    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.

  2. Change From Baseline in Paroxysmal Nocturnal Hemoglobinuria (PNH) Red Blood Cell (RBC) Count [ Time Frame: Baseline, Week 12 ]
  3. Number of Units of Packed Red Blood Cells (pRBCs) Transfused [ Time Frame: 12 weeks pre-treatment, baseline, 12 weeks post-treatment ]
    Comparison of number of units of pRBCs transfused in the 12 weeks prior to the first dose of eculizumab, and between baseline and 12 weeks after the first dose of eculizumab

  4. Change From Baseline in Lactate Dehydrogenase (LDH) Area Under the Curve (AUC) [ Time Frame: Baseline to Week 12 ]
  5. Change From Baseline in Plasma Free Hemoglobin [ Time Frame: Baseline, Week 12 ]
  6. Change From Baseline in European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30 Score (Global Health Status) [ Time Frame: Baseline, Week 12 ]
    The European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ) incorporates 5 functional scales (physical, role, cognitive, emotional, and social), 3 symptom scales (fatigue, pain, and nausea and vomiting), a global health status scale, and a number of single items assessing additional symptoms commonly reported by cancer patients (dyspnoea, loss of appetite, insomnia, constipation and diarrhea) and perceived financial impact of the disease. All of the scales and single-item measures range in score from 0 to 100. For global health status, a high score represents a high quality of life.
