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

Study Type : | Observational |
Actual Enrollment : | 69 participants |
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. |
Study Start Date : | October 2011 |
Actual Primary Completion Date : | June 2014 |
Actual Study Completion Date : | July 2015 |

Group/Cohort | Intervention/treatment |
---|---|
Group 1 |
Drug: Recombinant Factor VIII (Kogenate FS, BAY14-2222)
Prophylactic treatment : 20-40 UI /Kg administered all 2 in 3 days . |
- 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 ]
- 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 ]
- 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 ]
- The dosage of factor VIII calculated by OPTIMS calculator [ Time Frame: within 48 hours after enrollment ]
- The practicality of the OPTIMS calculator by a physician's satisfaction questionnaire [ Time Frame: within 48 hours after enrollment ]

Ages Eligible for Study: | Child, Adult, Older Adult |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Sampling Method: | Non-Probability Sample |
- 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
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
