Brief Summary
This is an open-label, single-arm, multi-center phase II study consisting of two cohorts. Cohort 1 evaluates the pharmacokinetics (PK) of TQ05105 in myelofibrosis participants with normal, mild, or moderate renal impairment to guide dosing. Cohort 2 evaluates the efficacy and safety of TQ05105 in participants with intermediate/high-risk myelofibrosis who are refractory, relapsed, or intolerant to prior Janus kinase (JAK) inhibitor therapy.
