Safety and Pharmacokinetics of Subcutaneous Injection of OCTA101 in Adult Patients With Severe Hemophilia A

Sponsor: Octapharma

Summary

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.
