Bomedemstat en pacientes con policitemia vera
Un estudio abierto, multicéntrico de fase 2 para evaluar la seguridad, la eficacia, la farmacocinética y la farmacodinámica de bomedemstat en pacientes con policitemia vera (PV)
Este es un estudio abierto de Fase 2 de un inhibidor de LSD1 administrado por vía oral, bomedemstat (IMG-7289), en pacientes con policitemia vera.
Este estudio investiga lo siguiente:
- La seguridad y tolerabilidad de bomedemstat
- El efecto farmacodinámico de bomedemstat
Descripción general del estudio
Descripción detallada
Este es un estudio abierto, multicéntrico y de fase 2 que evalúa la seguridad, la eficacia, la farmacocinética y la farmacodinámica de bomedemstat administrado por vía oral una vez al día en pacientes con policitemia vera.
Los pacientes recibirán 36 semanas de dosificación y pueden calificar para un tratamiento adicional a partir de entonces.
Los pacientes serán seguidos de cerca durante todo el estudio para ambos eventos adversos mediante el control frecuente de los signos y síntomas clínicos, así como los laboratorios de seguridad. La eficacia y los efectos farmacodinámicos se controlarán de cerca mediante evaluaciones hematológicas frecuentes de sangre periférica. A lo largo de la dosificación, se pueden administrar transfusiones o flebotomías si es necesario de acuerdo con las pautas institucionales estándar.
Para garantizar la seguridad, un Consejo Asesor de Seguridad realizará revisiones periódicas de los parámetros de seguridad y los marcadores farmacodinámicos.
