Brief Summary:
The purpose of this study is to evaluate the safety and tolerability of orally administered TG101348 in patients with myelofibrosis.

Condition or disease Intervention/treatment Phase
Myelofibrosis Drug: TG101348 Phase 1

Detailed Description:
TG101348 is a potent small molecule inhibitor of Janus kinase 2 (JAK2). This is a first-in-human study that will include a dose-escalation phase, to establish the maximum tolerated dose, and an expanded cohort, dose-confirmation phase. The safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary clinical activity of TG101348 in patients with myelofibrosis will be evaluated.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 59 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1, Open-label, Dose-escalation Study Evaluating the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Orally Administered TG101348 in Patients With Primary, Post-polycythemia Vera, or Post-essential Thrombocythemia Myelofibrosis
Study Start Date : January 2008
Actual Primary Completion Date : October 2009
