Filter by:This Phase 1/2 study will be a dose escalation study in adults in 5 cohorts (named cohorts 1, 2, 3, 5 and 6), with the main purpose to assess the safety of subcutaneous injection of OCTA101 (a human-cl rhFVIII and recombinant human von Willebrand Factor fragment dimer) in previously treated adult patients with severe hemophilia A. The study also aims to assess the pharmacokinetics (PK) characteristics, dose proportionality, and subcutaneous bioavailability of OCTA101 compared with intravenous administration of Nuwiq (Human-cl rh FVIII), in order to define the prophylactic treatment (dose and injection interval) that would result in protective trough levels of FVIII:C for future Phase 3 studies. Cohorts 1, 2, 3 and 5 will undergo a single injection of OCTA101, with cohorts 1, 2 and 3 proceeding to 3-month daily dosing prophylactic treatment for 3 months by Data Monitoring Committee recommendation. Cohorts 1 and 2 will undergo a further PK at the end of the daily injection period. A further cohort, cohort 6, will have an initial 4 to 6-week run-in treatment period with Nuwiq intravenous prophylaxis followed by 12.5 IU/kg OCTA101 subcutaneous daily prophylaxis for >3 up to 6-7 months.
A prospective, non-controlled, international, multi-centre phase 3 study to investigate the pharmacokinetics, efficacy, safety, and immunogenicity of Wilate in previously treated children with severe haemophilia A
The purpose of this study is to obtain additional data on the safety and efficacy of Wilate in PTPs with hemophilia A with at least 150 previous exposure days (EDs) to a FVIII concentrate who undergo prophylactic treatment with Wilate for 6 months and at least 50 EDs, thus supplementing the existing database to obtain approval of Wilate for the indication hemophilia A in the USA.
The primary objective of the study is to compare the pharmacokinetic (PK) of recombinant coagulation factor VIII Fc fusion protein (rFVIIIFc) manufactured at the current scale of 2000 L (2K) to the PK of rFVIIIFc manufactured at the 15,000 L (15K) scale in previously treated participants with severe hemophilia A. The secondary objectives are: to characterize the PK of rFVIIIFc manufactured at the 15K scale at the 15K baseline and after 13 weeks of treatment; to characterize the PK of rFVIIIFc manufactured at the 15K scale at 1000 IU/vial and 6000 IU/vial strengths; and to evaluate the safety of rFVIIIFc manufactured at the 15K scale.
This study will evaluate if Eloctate is superior to Emicizumab in reducing inhibitors in children with severe hemophilia when given before the first bleed (preemptive) and continued weekly to prevent bleeds (prophylaxis); and whether Eloctate immune tolerance induction (ITI) plus emicizumab is superior to Eloctate ITI alone in eradicating inhibitor formation in children and adults with severe hemophilia A.
This multicenter, open-label, phase 3 extension study will investigate the safety and efficacy of rVIII-SingleChain for prophylaxis and on-demand treatment of bleeding episodes in at least 200 previously treated patients (PTPs) with severe congenital hemophilia A and previous exposure to FVIII products who achieve at least 100 exposure days (EDs) to rVIII-SingleChain in this study, as well as in previously untreated patients (PUPs) with no previous exposure to any FVIII product who achieve at least 50 EDs to rVIII-SingleChain in this study. A substudy (open to both PTPs and PUPs) will investigate the use of rVIII-SingleChain in surgery. A substudy (open to PUPs who develop an inhibitor to rVIII-SingleChain) will investigate the use of rVIII-SingleChain in immune tolerance induction (ITI) therapy.
The primary objective of the study is to characterize the pharmacokinetics (PK) of rFVIIIFc administered at vial strengths of 1000 and 3000 IU in subjects with severe hemophilia A. The secondary objective of the study is to evaluate the safety of rFVIIIFc beyond the PK assessment for up to 6 months for a continued treatment period.
The purpose of the study is to collect long-term data on the inhibitor development rate of Human-cl rhFVIII in previously untreated patients with severe Hemophilia A.
Investigate the inhibitor development rate of Human cl rhFVIII in previously untreated patients with severe Hemophilia A.
The purpose of this pilot R34 trial is to determine the feasibility of a large single dose Phase III study of hemophilia adult prophylaxis comparing once weekly with thrice-weekly recombinant factor VIII. Efficacy will measured by bleeding frequency, factor usage, joint range of motion, cost, quality-of-life, F.VIII level, and inter-dose hypocoagulability by thrombin generation. Safety will be measured by inhibitor formation and bleeding events unresponsive to up to two rescue doses.
