Further study details as provided by TargeGen:

Primary Outcome Measures:
  • Safety (i.e., adverse events; effects on laboratory parameters, vital signs, and ECGs; dose-limiting toxicities), tolerability, and MTD [ Time Frame: 28 days ]

Secondary Outcome Measures:
  • Pharmacokinetics and pharmacodynamics [ Time Frame: 28 days ]

Enrollment: 59
Study Start Date: January 2008
Study Completion Date: October 2009
Primary Completion Date: October 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1 Drug: TG101348
Orally administered, once a day, for 28 days, up to 6 cycles.

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.
