Who this trial is looking for
This trial is looking for people with chronic myeloid leukemia who have already tried other treatments without success. Participants will help researchers learn about the safety of a new medication called MK-4208 at different doses.
Are You a Good Fit for This Trial?
You may be able to join if
I have a diagnosis of chronic myeloid leukemia in the chronic phase.
I have received treatment with at least one prior tyrosine kinase inhibitor.
I have not had success or tolerated my previous treatments well.
I have an ECOG performance status score of 0 to 2.
I have adequate organ function.
I have completed previous anticancer therapy without significant ongoing side effects.
You may not be able to join if
I have had any systemic antineoplastic therapy in the last 7 days.
I have not resolved all associated clinically significant toxicity from previous treatments.

Researchers are looking for a new way to treat a blood cancer called chronic myeloid leukemia (CML). Researchers want to learn if MK-4208 (Tern-701) can treat this type of blood cancer.
The goal of this study is to learn about the safety of different doses (amounts) of MK-4208 (Tern-701) and if people tolerate them. Researchers also want to find the highest dose of MK-4208 (Tern-701) that people …
