研究概览
简要总结
This multicenter, open-label, phase 1 study designed to evaluate safety and tolerability of multi-kinase inhibitor LNK01002 in patients with primary myelofibrosis (PMF), or MF due to polycythemia vera (PV-MF), or essential thrombocythemia (ET-MF), polycythemia vera (PV), or with acute myeloid leukemia (AML).
详细描述
This is a Phase I, open-label, dose-finding study of the triple kinase inhibitor LNK01002 in patients with Malignant Myeloid Hematologic Neoplasms. The study consists of two periods: the dose escalation, main period and a dose expansion period. In the dose escalation period, successive cohorts of patients with Malignant Myeloid Hematologic Neoplasms will be enrolled to establish the maximum tolerated dose. In the dose expansion period (dose-confirmation phase), three cohorts of patients will be enrolled: AML patients with confirmed FLT3-ITD mutations, AML patients without FLT3-ITD mutations, and patients with primary MF ,PV or PV/ET-MF.
The safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary clinical activity of LNK01002 in patients with Malignant Myeloid Hematologic Neoplasms will be evaluated.
