Key inclusion & exclusion criteria
|
Inclusion criteria: In order to qualify for study enrolment, the following criteria must be fulfilled before study entry: 1. Male patients 2. Severe haemophilia A (FVIII:C < 1%) 3. No previous treatment with FVIII concentrates or other blood products containing FVIII 4. Voluntarily given, fully informed written and signed consent given before any study related procedures are conducted (obtained from the patient?s parent(s)/legal guardian(s)) Are the trial subjects under 18? yes Number of subjects for this age range: 100 F.1.2 Adults (18-64 years) no F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range
Exclusion criteria: Patients will not be included if any of the following exclusion criteria are met: 1. Diagnosis of a coagulation disorder other than haemophilia A 2. Severe liver or kidney disease (ALT or AST levels >5 times of upper limit of normal (ULN), creatinine >120 µmol/L) 3. Concomitant treatment with any systemic immunosuppressive drug 4. Participation in another interventional clinical study currently or during the past 4 weeks

Severe Haemophilia A MedDRA version: 15.1

Intervention(s)
|
Product Name: Human cell line recombinant factor VIII Product Code: Human-cl rhFVIII Pharmaceutical Form: Powder and solvent for solution for injection INN or Proposed INN: Human-cl rhFVIII CAS Number: N.A Current Sponsor code: 140 Other descriptive name: Human Coagulation Factor VIII Concentration unit: IU international unit(s) Concentration type: range Concentration number: 250-2000
|
Primary Outcome(s)
|
Main Objective: To investigate the immunogenicity of Human-cl rhFVIII in 100 PUPs suffering from severe haemophilia A (FVIII:C < 1%).
|
Secondary Objective: - To assess the efficacy of Human-cl rhFVIII during prophylactic treatment (based on the frequency of spontaneous break-through bleeds) - To assess the efficacy of Human-cl rhFVIII during treatment of bleeds - To assess the efficacy of Human-cl rhFVIII in surgical prophylaxis - To assess the safety and tolerability of Human-cl rhFVIII
|
Timepoint(s) of evaluation of this end point: -At baseline (Screening Visit) - Every 3-4 EDs until ED 20 - Every 10-12 EDs or every 3 months ± 2 weeks (whichever comes first) after ED 20 until 100 EDs are reached - Any time in the case of suspicion of an inhibitor development
|
Primary end point(s): Immunogenicity of Human-cl rhFVIII is the primary endpoint. Inhibitor activity will be determined by the modified Bethesda assay (Nijmegen modification), using congenital FVIIIdeficient human plasma, spiked with Human-cl rhFVIII. In case of a positive inhibitor result, an inhibitor retesting, using a second separately drawn sample, should be performed. A FVIII inhibitor is defined as ?positive?, if the retesting confirms the positive result, otherwise the result is considered as being ?negative?.
|
Secondary Outcome(s)
|
Secondary end point(s): 1)Efficacy a) Efficacy of prophylactic treatment The efficacy of Human-cl rhFVIII in the prophylactic treatment will be investigated by calculating the frequency of spontaneous break-through bleeds under prophylactic treatment. Study drug consumption data (FVIII IU/kg per month, per year) per patient and in total will be evaluated. The dates and times of study drug infusions, the details of dose(s), and the product batch numbers used for the prophylactic treatment will be documented. b) Efficacy of treatment of bleeds The efficacy of Human-cl rhFVIII in the treatment of bleeds will be investigated by using a 4-point ordinal haemostatic efficacy scale. Details of the bleed, the amount of Human-cl rhFVIII needed and the number of injections necessary to stop the bleed will be documented. c) Efficacy of surgical prophylaxis In surgical procedures, the following parameters will be documented: ? Overall efficacy assessment (taking into account the intra- and post-operative assessment) after the end of surgical prophylactic treatment phase, performed by the surgeon and by the haematologist. ? Average and maximum expected estimated blood loss, compared to the actual estimated blood loss. ? Details on surgical procedure: location, severity, type, expected and actual duration ? Pre-, intra-, and post-operative FVIII plasma levels, if appropriate ? Details of administered dose(s) of Human-cl rhFVIII given pre-, intra- and/or postoperatively including dates, times and batch numbers ? Details on concomitantly administered drugs, including all blood and blood product transfusions, excluding standard anaesthetic drugs ? Details on all wound haematomas in terms of capturing, analysing, and reporting these, including any need for surgical evacuation ? Outcome of the intervention, described by means of a brief narrative 2.Safety Safety and tolerability will be assessed by monitoring vital signs, standard laboratory parameters, and by monitoring adverse events (AEs).

Timepoint(s) of evaluation of this end point: 1)Efficacy In the prevention and the treatment of bleeds, the frequency of break-through bleeds in case of prophylactic treatment, the efficacy in surgical prophylaxis of Human-cl rhFVIII will be thoroughly assessed. In the course of the follow-up visits (i.e. every 3-4 EDs until ED 20, then every 10-12 EDs until ED 100), scheduled to be performed after the Screening Visit, FVIII inhibitor levels will be assessed. These visits may be combined with the additional regular 3 monthly (± 2 weeks) follow-up visits. 2) Safety AEs and changes in concomitant medication, overall safety and tolerability will be checked and documented at each follow-up visit.
