A Phase 1/2 Study of SB1518 for the Treatment of Advanced Myeloid Malignancies
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
This 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 advanced myeloid malignancies; the second portion of the study is a Phase 2 study to define the efficacy and safety profile of single-agent SB1518 at the recommended dose in subjects with chronic idiopathic myelofibrosis (CIMF).

In Phase 2, subjects with CIMF (as well as post ET/PV MF)
Eastern Cooperative Oncology Group (ECOG) performance status 0-2
All men of reproductive potential and women of child-bearing potential must agree to practice effective contraception during the entire study period and for one month after the last study treatment, unless documentation of infertility exists.

Able to understand and willing to sign the informed consent form
Subjects with Chronic Myelogenous Leukemia (CML) in chronic phase;
Uncontrolled inter-current illness including, but not limited to, ongoing active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements as judged by treating physician. Subjects receiving antibiotics for infections that are under control may be included in the study;
