Bomedemstat chez les patients atteints de polycythémie vraie
Une étude ouverte multicentrique de phase 2 pour évaluer l'innocuité, l'efficacité, la pharmacocinétique et la pharmacodynamique du bomedemstat chez les patients atteints de polycythémie vraie (PV)
Il s'agit d'une étude ouverte de phase 2 portant sur un inhibiteur du LSD1 administré par voie orale, le bomedemstat (IMG-7289), chez des patients atteints de polycythémie vraie.
Cette étude examine les éléments suivants :
- L'innocuité et la tolérabilité du bomedemstat
- L'effet pharmacodynamique du bomedemstat
Aperçu de l'étude
Description détaillée
Il s'agit d'une étude ouverte multicentrique de phase 2 évaluant l'innocuité, l'efficacité, la pharmacocinétique et la pharmacodynamique du bomedemstat administré par voie orale une fois par jour chez des patients atteints de polycythémie vraie.
Les patients recevront 36 semaines de dosage et pourront bénéficier d'un traitement supplémentaire par la suite.
Les patients seront suivis de près tout au long de l'étude pour les deux événements indésirables par une surveillance fréquente des signes et symptômes cliniques ainsi que des laboratoires de sécurité. L'efficacité et les effets pharmacodynamiques seront étroitement surveillés par des évaluations hématologiques fréquentes du sang périphérique. Tout au long du dosage, des transfusions ou une phlébotomie peuvent être administrées si nécessaire conformément aux directives institutionnelles standard.
Pour assurer la sécurité, un comité consultatif de sécurité effectuera des examens périodiques des paramètres de sécurité et des marqueurs pharmacodynamiques.
