Evaluating Safety ,Tolerability, Pharmacokinetic,Efficacy of WJ01024 or WJ01024 Combined With Ruxolitinib in Patients With Myelofibrosis

1 september 2026 uppdaterad av: zhou, Henan Cancer Hospital

A Phase I Clinical Study Evaluating the Safety and Tolerability, Pharmacokinetic Characteristics and Preliminary Efficacy of Oral Administration of WJ01024 as a Monotherapy and in Combination With Ruxolitinib in Patients With Myelofibrosis

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.

Detaljerad beskrivning

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).Dose escalation is carried out by combining accelerated titration and the traditional 3+3 design. During the accelerated titration phase, if no dose-limiting toxicity (DLT) and no ≥2 episodes of grade ≥2 treatment-related adverse events (TRAEs) occur within the first cycle (DLT observation period), no further subjects are enrolled at that dose level, and the study proceeds to the traditional 3+3 phase starting with the 60 mg group. At present, it is expected that the dose will be increased in four groups . If the researchers elects to explore intermediate doses or higher doses during the trial, adjustments will be made based on the actual situation. It is planned to expand the dosage by two groups. The final expanded dosage will be determined based on emerging safety and efficacy data. Dose escalation is stratified by background therapy (with vs. without background medication). Phase IB involves dose escalation and dose expansion studies of WJ01024 combined with ruxolitinib. Phase IB is planned to be conducted in JAKi-naïve patients with intermediate- or high-risk MF. Initiation of Phase IB requires that the group in Phase IA has completed the DLT observation period. Two combination dose groups are planned. Intermediate or higher doses may be explored at the investigator's discretion.Two combination dose levels are planned for expansion ;final expansion dose(s) will be determined based on emerging safety and efficacy data.
