Tutkimus lääkkeen (Fitusiran) testaamiseksi verenvuotojen ehkäisemiseksi ihmisillä, joilla on vaikea hemofilia ja jotka ovat aiemmin saaneet ennaltaehkäisevää hoitoa emitsitsumabilla
Avoin, yhden käden hoitotutkimus, jossa tutkitaan emitistsumabista Fitusiran-profylaksiin siirtymisen turvallisuutta ja siedettävyyttä yli 18-vuotiailla miehillä, joilla on vaikea hemofilia A, estäjillä tai ilman
This is an exploratory, single group, Phase 4, study to assess treatment with fitusiran prophylaxis after switching from emicizumab prophylaxis.
This study aims to evaluate the safety and tolerability of switching to fitusiran after a transition period from the last dose of emicizumab. The study will be conducted in male participants with severe hemophilia A, with or without inhibitors, aged ≥12 years, who were previously receiving emicizumab prophylaxis.
Study details include:
-
The study duration will be up to approximately 28 months:
- There will be an approximately 2-month screening period.
- There will be an approximately 2-month period before fitusiran treatment starts (pre-fitusiran treatment period)
- The fitusiran treatment duration will be up to 18-months (fitusiran treatment period)
- The antithrombin (AT) follow-up (FU) period will be approximately 6 months after the last dose of fitusiran (during which the AT activity level will be monitored at approximately monthly intervals following the final fitusiran dose until AT activity levels return to at least 60%).
-
The study site visits are scheduled at monthly/ every 2 months intervals of 28 days (4 weeks) / 56 days (8 weeks), respectively, during the fitusiran treatment period.

Kokeellinen: fitusiran
The pre-fitusiran treatment period is defined as the transition period up to the first fitusiran administration. Participants will receive on demand or prophylactic treatment with intravenous clotting factor concentrates (IV CFCs) or bypassing agents (BPAs) from Month-2 until Day 1. Fitusiran treatment period: Participants will receive subcutaneous (SC) fitusiran prophylaxis once every 2 months (Q2M) or once monthly (QM) from Day 1 until Month18. Participants may receive IV antithrombin concentrate (ATIIIC) upon investigator's judgement. AT FU period: Participants will be followed up until AT activity levels recover to at least 60% (per central laboratory). In case of bleeding events participants will receive IV CFCs or BPAs. Participants may receive IV ATIIIC upon investigator's judgement. |
