NCT01064284
First received: February 4, 2010
Last updated: August 19, 2011
Last verified: August 2011
  Purpose

The primary objective of the study is to assess the immunogenicity of VWF/FVIII and of rFVIII concentrates by determining the frequency of inhibitor development in previously untreated patients (PUPs) or minimally blood component-treated (MBCTPs) in the first 50 EDs or in the first 3 years from enrollment, whichever occurs first.

Masking: Open Label
Primary Purpose: Basic Science
Official Title: Inhibitor Development in Previously Untreated Patients (PUPs) or Minimally Blood Component-Treated Patients (MBCTPs) When Exposed to Plasma-derived Von Willebrand Factor-Containing Factor VIII (VWF/FVIII) Concentrates and to Recombinant Factor VIII (rFVIII) Concentrates: An Independent, International, Multicentre, Prospective, Controlled, Randomised, Open Label, Clinical Trial

Primary Outcome Measures:
  • Frequency of FVIII inhibitor formation in patients treated with plasma-derived vWF/FVIII compared to patients treated with recombinant FVIII [ Time Frame: During the first 50 exposure days or first 3 years of enrollment, whichever occurs first ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To evaluate the frequency of transient inhibitors [ Time Frame: in the 6 months after inhibitor development or untill the immunosoppresive treatment ] [ Designated as safety issue: Yes ]
  • To evaluate the modality of occurrence of inhibitors (number of EDs, titre at onset, etc) [ Time Frame: During the first 50 exposure days or first 3 years of enrollment, whichever occurs first ] [ Designated as safety issue: No ]
  • Evaluate clinical factors potentially associated to inhibitor development(age at first treatment, severity of bleeding,surgery,intensity of treatment,time of treatment in relation to vaccinations,concurrent disease) [ Time Frame: During the first 50 exposure days or first 3 years of enrollment, whichever occurs first ] [ Designated as safety issue: No ]
  • To evaluate the incidence of all other adverse events related and not related to the products used [ Time Frame: During the first 50 exposure days or first 3 years of enrollment, whichever occurs first ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 300

Detailed Description:

Patients meeting the enrollment criteria will be consecutively enrolled at each participating centre, randomized to be treated exclusively with a single FVIII product either plasma-derived or recombinant, and followed up until inhibitor development or until 50 exposure days (EDs) or 3 years from enrolment have elapsed, whichever comes first. Study products, belonging to the class of rFVIII concentrates and to the class of plasma-derived VWF/FVIII concentrates, will be provided for free to the patients for all the duration of the study

  Eligibility

Ages Eligible for Study:   up to 6 Years
Genders Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Male subjects
  • Any ethnicity
  • Age <6 years
  • Severe haemophilia A (FVIII:C <1%), as confirmed at enrolment by the central laboratory.

    o Those patients diagnosed locally as severe but subsequently found to have FVIII levels >= 1% on testing at the central laboratory will be separately recorded in the screening list.

  • Previously untreated (0 EDs to any FVIII concentrates or blood products) or minimally treated (<5 EDs) with blood components, namely whole blood, fresh frozen plasma, packed red blood cells, platelets or cryoprecipitate.

    o Patients not meeting these criteria will be separately recorded in the screening list.

  • Negative inhibitor measurement at both local and central laboratory at screening
  • Ability to comply with study requirements
  • Signed informed consent of legal tutors o Patients who will not accept to enter into the study or to be randomized will be separately recorded.

Exclusion Criteria:

  • Previous history of FVIII inhibitor
  • Other congenital or acquired bleeding defects
  • Plasma FVIII level >= 1%, as assayed at the central laboratory

    o Those patients originally diagnosed locally as severe but subsequently found to have FVIII levels ranging from 1% to 2% on testing at the central laboratory will be separately recorded in the screening list.

  • Concomitant congenital or acquired immunodeficiency
  • Concomitant treatment with systemic immunosuppressive drugs
  • Concomitant treatment with any investigational drug
