Bomedemstat hos patienter med polycytemi Vera
En fas 2 multicenter, öppen etikettstudie för att bedöma säkerheten, effekten, farmakokinetiken och farmakodynamiken hos Bomedemstat hos patienter med polycytemi Vera (PV)
Detta är en öppen fas 2-studie av en oralt administrerad LSD1-hämmare, bomedemstat (IMG-7289), hos patienter med polycytemi vera.
Denna studie undersöker följande:
- Säkerheten och tolerabiliteten för bomedemstat
- Den farmakodynamiska effekten av bomedemstat
Studieöversikt
Detaljerad beskrivning
Detta är en öppen fas 2 multicenterstudie som utvärderar säkerheten, effekten, farmakokinetiken och farmakodynamiken för bomedemstat administrerat oralt en gång dagligen till patienter med polycytemia vera.
Patienterna kommer att få 36 veckors dosering och kan kvalificera sig för ytterligare behandling därefter.
Patienterna kommer att följas noga under hela studien för båda biverkningarna genom frekvent övervakning av kliniska tecken och symtom samt säkerhetslabb. Effekt och farmakodynamiska effekter kommer att övervakas noggrant genom frekventa hematologiska bedömningar av perifert blod. Under hela doseringen kan transfusioner eller flebotomi administreras vid behov i enlighet med institutionella standardriktlinjer.
För att garantera säkerheten kommer en säkerhetsråd utföra periodiska granskningar av säkerhetsparametrar och farmakodynamiska markörer.
