What the trial is, and whether it could suit you
This is a Phase I clinical study to evaluate the safety and tolerability, pharmacokinetic characteristics and preliminary efficacy of oral WJ01024 administered as monotherapy and in combination with ruxolitinib in patients with myelofibrosis（MF）. The study will be conducted in two phases: Phase IA and Phase IB.
Phase IA is a dose-escalation and dose-expansion study of WJ01024 monotherapy in patients with MF after failure of JAK inhibitor (JAKi) therapy (relapsed/refractory/intolerant). Phase IB is a dose-escalation and dose-expansion study of WJ01024 in combination with ruxolitinib in JAKi-naïve patients with intermediate- or high-risk MF.
