Study Details

Study Description

Brief Summary

This is a Phase 3b, single-arm, open-label, multicenter study to evaluate the efficacy, safety, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of eculizumab in adult participants with paraxysmal noturnal hemoglobinuria (PNH) in China.

Condition or Disease Intervention/Treatment Phase
Phase 3

Detailed Description

This is a Phase 3b, single-arm, open-label, multicenter study to evaluate the efficacy, safety, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of eculizumab in adult participants with PNH in China who previously have not been treated with complement inhibitors. Approximately 25 eligible participants in China will be enrolled.

Outcome Measures

Primary Outcome Measures

  1. Percentage change from baseline in Lactate Dehydrogenase (LDH) at Week 12 [Baseline, Week 12]

    To assess efficacy of eculizumab in participants with PNH

Secondary Outcome Measures

  1. Number(%) of participants with Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) [Baseline through Week 64]

    To assess the safety and tolerability of eculizumab in participants with PNH

  2. Pharmacokinetics (PK): Serum Eculizumab Concentration [Baseline through Week 64 (predose and postdose)]

    To characterize the pharmacokinetics of eculizumab in participants with PNH

  3. Change from baseline in Serum Free and total Complement 5 (C5) Concentration [Baseline through week 64 (predose and postdose)]

    To characterize the pharmacodynamics of eculizumab in participants with PNH

  4. Number(%) of participants with Antidrug Antibodies (ADAs) to Eculizumab [Baseline through Week 64]

    To characterize the immunogenicity of eculizumab in participants with PNH

  5. Change from baseline in functional assessment of Chronic Illness Therapy (FACIT)-Fatigue Score at Week 64 [Baseline through Week 64]

    To assess the efficacy of eculizumab in participants with PNH

  6. Number(%) of participants with Breakthrough Hemolysis [Baseline through Week 64]

    To assess the efficacy of eculizumab in participants with PNH

  7. Number(%) of participants achieving LDH Normalization [Baseline through Week 64]

    To assess the efficacy of eculizumab in participants with PNH

  8. Number(%) of participants needing Blood Transfusion [Baseline through Week 64]

    To assess the efficacy of eculizumab in participants with PNH

  9. Number(%) of participants changes from baseline in vital signs and laboratory parameters at all scheduled visits. [Baseline through Week 64]

    To characterize the safety profile of eculizumab in participants with PNH
