Descriptive Information
Brief Title  ICMJE Efficacy, Safety, and Pharmacokinetic Study of Prophylactic Emicizumab Versus No Prophylaxis in Hemophilia A Participants
Official Title  ICMJE A Randomized, Multicenter, Open-Label, Phase III Clinical Trial to Evaluate the Efficacy, Safety, and Pharmacokinetics of Prophylactic Emicizumab Versus No Prophylaxis in Hemophilia A Patients
Brief Summary This randomized, multicenter, open-label, Phase 3 study is designed to investigate the efficacy, safety, and pharmacokinetics of emicizumab in participants with hemophilia A regardless of factor VIII (FVIII) inhibitor status. Participants who received episodic therapy with FVIII or bypassing agents prior to study entry and experienced at least 5 bleeds over the prior 24 weeks will be randomized in a 2:2:1 ratio to the following regimens: 1) Emicizumab prophylaxis at 3 milligrams per kilogram (mg/kg) every week (QW) subcutaneously (SC) for 4 weeks, followed by 1.5 mg/kg QW SC; 2) Emicizumab prophylaxis at 3 mg/kg QW SC for 4 weeks, followed by 6 mg/kg every 4 weeks (Q4W) SC; 3) No prophylaxis (control arm).
Detailed Description Not Provided
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 3
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Condition  ICMJE Hemophilia A
Intervention  ICMJE Drug: Emicizumab
Emicizumab will be administered via SC injection.
Other Name: RO5534262
Study Arms  ICMJE
  • Experimental: Prophylactic Emicizumab 1.5 mg/kg QW
    Participants will receive prophylactic emicizumab at a dose of 3 mg/kg via SC injection QW for first 4 weeks, followed by 1.5 mg/kg via SC injection QW up to 24 weeks. After 24 weeks treatment, participants will be allowed to continue emicizumab until marketing authorization as part of this study or a separate extension study.
    Intervention: Drug: Emicizumab
  • Experimental: Prophylactic Emicizumab 6 mg/kg Q4W
    Participants will receive prophylactic emicizumab at a dose of 3 mg/kg via SC injection QW for first 4 weeks, followed by 6 mg/kg via SC injection Q4W (or 3 mg/kg Q2W if Q4W is not to be pursued) up to 24 weeks. After 24 weeks treatment, participants will be allowed to continue emicizumab until marketing authorization as part of this study or a separate extension study.
    Intervention: Drug: Emicizumab
  • Control Arm: No Prophylaxis
    Participants will not receive any prophylactic treatment up to 24 weeks. After 24 weeks, participants will have the opportunity to switch to receive emicizumab prophylaxis at 3 mg/kg QW via SC injection for 4 weeks, followed by 6 mg/kg Q4W (or 3 mg/kg Q2W if Q4W is not to be pursued), until marketing authorization as part of this study or a separate extension study.
    Intervention: Drug: Emicizumab

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Diagnosis of severe congenital hemophilia A or hemophilia A with FVIII inhibitors
  • Body weight greater than or equal to (>/=) 40 kilograms at the time of screening
  • Participants without FVIII inhibitors (< 0.6 Bethesda unit per milliliter [BU/mL]) who completed successful immune tolerance induction (ITI) must have done so at least 5 years before screening and have no evidence of inhibitor recurrence (permanent or temporary)
  • Documentation of the details of episodic therapy (FVIII or bypassing agents) and of number of bleeding episodes for at least the last 24 weeks and >/=5 bleeds in the last 24 weeks prior to study entry
  • Adequate hematologic, hepatic, and renal function
  • For women of child bearing potential: agreement to remain abstinent or use a protocol defined contraceptive measures during the treatment period and for at least 5 elimination half-lives (24 weeks) after the last dose of study drug

Exclusion Criteria:

  • Inherited or acquired bleeding disorder other than hemophilia A
  • Participants who are at high risk for thrombotic microangiopathy, in the investigator's judgment
  • History of illicit drug or alcohol abuse within 48 weeks prior to screening, in the investigator's judgment
  • Previous (in the past 12 months) or current treatment for thromboembolic disease (with the exception of previous catheter-associated thrombosis for which anti-thrombotic treatment is not currently ongoing) or signs of thromboembolic disease
  • Other conditions that may increase risk of bleeding or thrombosis
  • History of clinically significant hypersensitivity associated with monoclonal antibody therapies or components of the emicizumab injection
  • Known human immuno-deficiency virus (HIV) infection with cluster of differentiation (CD)4 count <200 cells/microliter (cells/mcL) within 24 weeks prior to screening. Participants with HIV infection who has CD4 >200 cells/mcL and meet all other criteria are eligible
  • Use of systemic immunomodulators at enrollment or planned use during the study, with the exception of anti-retroviral therapy
  • Concurrent disease, treatment, or abnormality in clinical laboratory tests that could interfere with the conduct of the study, may pose additional risk, or would, in the opinion of the investigator, preclude the participant's safe participation in and completion of the study
  • Planned surgery (excluding minor procedures such as tooth extraction or incision and drainage) during the study
  • Receipt of: Emicizumab in a prior investigational study; An investigational drug to treat or reduce the risk of hemophilic bleeds within 5 half-lives of last drug administration; A non-hemophilia-related investigational drug concurrently, within last 30 days or 5 half-lives, whichever is shorter
  • Pregnant or lactating, or intending to become pregnant during the study
  • Women with positive serum pregnancy test result within 7 days prior to initiation of study drug
