Panobinostat (LBH589) and Imatinib Mesylate in Treating Patients With Previously Treated Chronic Phase Chronic Myelogenous Leukemia

Completed · Phase 1

Conditions studied: Leukemia

In brief

RATIONALE: Panobinostat and imatinib mesylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase I trial is studying the side effects and best dose of panobinostat when given together with imatinib in treating patients with previously treated chronic phase chronic myelogenous leukemia.

• Impaired cardiac function including any one of the following: Screening ECG with a QTc > 450 msec; Patients with congenital long QT syndrome; History or presence of sustained ventricular tachycardia; Any history of ventricular fibrillation or torsades de pointes; Bradycardia defined as heart rate < 50 beats per minute (patients with a pacemaker and heart rate >= 50 beats per minute are eligible); Patients with a myocardial infarction or unstable angina within 6 months of study entry; Congestive heart failure (NY Heart Association class III or IV); Right bundle branch block and left anterior hemiblock (bifascicular block)
• Uncontrolled hypertension
• Concomitant use of drugs with a risk of prolonging the QT interval or inducing torsades de pointes
• Concomitant use of CYP3A4 inhibitors
