A Phase 1/2 Study of Oral SB1518 in Subjects With Chronic Idiopathic Myelofibrosis

Summary

The study consists of two phases: The first portion of the study is a Phase 1 dose escalation study to determine the maximum tolerated dose and the dose limiting toxicities of SB1518 when given as a single agent orally once daily in subjects with Chronic Idiopathic Myelofibrosis (CIMF) regardless of their JAK2 mutational status.
