Asian Phase II Study of INC424 in Patients With Primary Myelofibrosis (MF), Post-PV MF or Post-ET MF

This study is ongoing, but not recruiting participants.

Novartis ( Novartis Pharmaceuticals ) Identifier:
First received: July 11, 2011
Last updated: March 6, 2017
Last verified: March 2017
The objective of this study is to determine the efficacy of INC424 as assessed by reduction in spleen volume in patients with primary myelofibrosis (MF), post-polycythemia vera (PV) MF, or post-essential thrombocythemia (ET) MF. The safety and tolerability of INC424 and the effects of INC424 on patient reported outcomes and the duration of response as assessed by reduction in spleen volume will also be assessed.

Condition Intervention Phase
Primary Myelofibrosis (MF) Post-Polycythemia Vera (PV) MF Post-Essential Thrombocythemia (ET) MF Drug: Ruxolitinib Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Multi-national Open-label Phase II Study of the JAK Inhibitor INC424 in Patients With Primary Myelofibrosis, Post-polycythemia Vera Myelofibrosis or Post-essential Thrombocythemia Myelofibrosis

Drug: Ruxolitinib
INC424 Tablet for oral use, provided in 5 mg bottles. The dosage strength is 5 mg/tablet INC424 phosphate (free base equivalent). Medication labels will be in the local language and comply with the legal requirements of each country. equivalent).
