  Purpose

OPTIMS is a non interventional validation study of the calculator developed by Bayer for clinician's use in the prophylactic treatment by factor VIII of patients with severe or moderate Haemophilia A with a severe clinical profile.

The study takes place during a single visit, at the time of patient enrollment in the study


Condition Intervention
Haemophilia A
Drug: Recombinant Factor VIII (Kogenate FS, BAY14-2222)

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Validation Study of the OPTIMS Pharmacokinetic Calculator for Clinician Use in Prophylactic Treatment of Patients With Haemophilia A.

Further study details as provided by Bayer:

Primary Outcome Measures:
  • The difference of the recovery rate calculated by the physician and the recovery rate calculated by an independent calculator With OPTIMS Tool [ Time Frame: after 1 month ] [ Designated as safety issue: No ]
  • The difference of the elimination half-life calculated by the physician and the ones calculated by an independent calculator With OPTIMS Tool [ Time Frame: after 1 month ] [ Designated as safety issue: No ]
  • The difference of the clearance calculated by the physician and the ones calculated by an independent calculator With OPTIMS Tool [ Time Frame: after 1 month ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The dosage of factor VIII calculated by OPTIMS calculator [ Time Frame: within 48 hours after enrollment ] [ Designated as safety issue: No ]
  • The practicality of the OPTIMS calculator by a physician's satisfaction questionnaire [ Time Frame: within 48 hours after enrollment ] [ Designated as safety issue: No ]

Estimated Enrollment: 100
Study Start Date: October 2011
Estimated Study Completion Date: September 2014

  Eligibility

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
  • Patient with severe haemophilia A defined as residual factor VIII activity < 1%
  • or Patient with moderate haemophilia A (residual factor VIII activity >1% and <5%) with clinical signs of frequent, severe bleeding episodes
  • Patient treated prophylatically with the same plasma or recombinant factor VIII for at least 6 months
Criteria

Inclusion Criteria:

  • Patient with severe haemophilia A defined as residual factor VIII activity < 1%
  • or Patient with moderate haemophilia A (residual factor VIII activity >1% and <5%) with severe clinical profile
  • Patient treated in prevention with the same plasma or recombinant factor VIII for at least 6 months
  • Patient whose inclusion visit is performed during a routine visit including a measurement of plasma residual factor VIII :c level
  • In the medical file (retrospective data) the pharmacokinetic parameters are available and have been obtained from a PK analysis of factor VIII level performed with the same anti haemophilic factor than the one used on the inclusion day

Exclusion Criteria:

  • Patients with haemophilia B
