Bomedemstat em pacientes com policitemia vera
Um estudo multicêntrico de Fase 2, aberto para avaliar a segurança, eficácia, farmacocinética e farmacodinâmica do Bomedemstat em pacientes com policitemia vera (PV)
Este é um estudo aberto de Fase 2 de um inibidor de LSD1 administrado por via oral, bomedemstat (IMG-7289), em pacientes com policitemia vera.
Este estudo investiga o seguinte:
- A segurança e tolerabilidade do bomedemstat
- O efeito farmacodinâmico do bomedemstat
Visão geral do estudo
Descrição detalhada
Este é um estudo aberto multicêntrico de Fase 2 que avalia a segurança, eficácia, farmacocinética e farmacodinâmica do bomedemstat administrado por via oral uma vez ao dia em pacientes com policitemia vera.
Os pacientes receberão 36 semanas de dosagem e podem se qualificar para tratamento adicional a partir de então.
Os pacientes serão acompanhados de perto durante todo o estudo para ambos os eventos adversos por monitoramento frequente de sinais e sintomas clínicos, bem como laboratórios de segurança. A eficácia e os efeitos farmacodinâmicos serão monitorados de perto por avaliações hematológicas frequentes do sangue periférico. Ao longo da dosagem, transfusões ou flebotomia podem ser administradas, se necessário, de acordo com as diretrizes institucionais padrão.
Para garantir a segurança, um Conselho Consultivo de Segurança realizará revisões periódicas dos parâmetros de segurança e marcadores farmacodinâmicos.
