About
This phase II trial studies how well edicotinib (JNJ-40346527) works in treating participants with acute myeloid leukemia that has come back or does not respond to treatment. JNJ-40346527 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
Full description
PRIMARY OBJECTIVE:
Evaluate preliminary efficacy of JNJ-40346527 in participants with relapsed/refractory AML.
I. Best objective response rate (> PR).
SECONDARY OBJECTIVES:
Assess safety and survival associated with JNJ-40346527 to treat participants with relapsed/refractory AML. Assess the duration of disease response associated with JNJ-40346527.
I. Overall incidence of treatment-related and non-treatment related toxicity. II. Duration of response. III. 12-month event-free survival. IV. 12-month overall survival.
EXPLORATORY OBJECTIVES:
I. Evaluate the pharmacokinetics of JNJ-40346527 and effective inhibition of CSF-1R in marrow aspirates using plasma inhibitory assays, with established CSF-1R-sensitive cell lines.
II. Identify the effect of JNJ-40346527 on leukemia cells and the immune microenvironment.
III. Identify and quantify the specific subpopulation of cells that express CSF-1R in participants and correlate these with clinical response to JNJ-40346527.
IV. Analyze the frequency of mutations using genomic deoxyribonucleic acid (DNA) from leukemia participants to determine if there is a genetic signature that predicts response to JNJ-40346527.
V. Using ribonucleic acid (RNA) sequencing (RNAseq), identify an expression signature in CSF-1R+ cells that predicts patient response.
VI. Evaluate the effect of JNJ-40346527 on immune cell populations (cytotoxic T cells, etc.) and phospho-signaling proteins by mass cytometry (CyTOF) analysis in pre- and post-treatment samples in order to identify biomarkers that predict patient response and prioritize potential combination strategies for future clinical trials.
VII. Determine how leukemia cells change in response to CSF-1R inhibition by assessing cells collected pre- and post-treatment using an ex vivo sensitivity to a panel of small molecule inhibitors to determine what new drug sensitivities may emerge in AML cells after CSF-1R inhibition.
OUTLINE:
Participants receive JNJ-40346527 orally (PO) twice a day (BID) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, participants are followed up within 2 weeks, at 4-6 weeks until death or minimum of 12 months.
