A Phase I/II Study of the Histone Deacetylase (HDAC) Inhibitor LBH589 (Panobinostat) in Combination With mTOR Inhibitor RAD001 (Everolimus) in Patients With Relapsed Multiple Myeloma or Lymphoma


Rochester, Minn.

Trial status:
Open for Enrollment
Why is this study being done?

PRIMARY OBJECTIVES: I. To determine the maximum tolerated doses (MTD) of LBH589 and RAD001 when used in combination in patients with myeloma or lymphoma (Phase I). II. Arm A: To evaluate the therapeutic activity of the combination of LBH589 with RAD001 in patients with relapsed or refractory lymphoma. (Phase II) III. Arm B: To evaluate the therapeutic activity of the combination of LBH589 with RAD001 in patients with relapsed or refractory multiple myeloma (Phase II) SECONDARY OBJECTIVES: I. To further describe the toxicities associated with the combination of LBH589 with RAD001 in each arm independently. II. To evaluate overall survival, progression-free survival, and duration of response in each arm independently. TERTIARY OBJECTIVES: I. To evaluate the pharmacokinetic interaction of LBH589 and RAD001. II. To assess the correlation between clinical (toxicity and/or tumor response or activity) effects with the pharmacologic (pharmacokinetic/pharmacodynamic) parameters, and/or biologic (correlative laboratory) results. OUTLINE: Patients receive oral panobinostat and oral everolimus once daily. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study, patients are followed periodically for 2 years.

NOTE: (patients who have received prior RAD001 therapy will be allowed but must meet above requirements) - Receiving corticosteroids > 20 mg of prednisone per day (or equivalent)NOTE: Patients may be receiving stable (not increased within the last month) chronic doses of corticosteroids with a maximum dose of 20 mg of prednisone per day if they are being given for disorders other than lymphoma (with the exception of CNS lymphoma, which steroids are permitted at the lowest possible dose necessary and should not be escalated during treatment) such as rheumatoid arthritis, polymyalgia rheumatica or adrenal insufficiency or asthma. - Persistent toxicities >= grade 2 from prior chemotherapy or biological therapy regardless of interval since last treatment - Patients with congenital long QT syndrome - History or presence of sustained ventricular tachyarrhythmia (patients with a history of atrial arrhythmia are eligible but should be discussed with the sponsor prior to enrollment) - Any history of ventricular fibrillation or torsade de pointes - Bradycardia defined as HR < 50 bpm (patients with pacemakers are eligible if HR >= 50 bpm) - Right bundle branch block + left anterior hemiblock (bifascicular block) - Patients with myocardial infarction or unstable angina =< 6 months prior to starting study drug - Other clinically significant heart disease (e.g., CHF NY Heart Association class III or IV) , uncontrolled hypertension, history of labile hypertension, or history of poor compliance with an antihypertensive regimen - Pregnant women or women of reproductive ability who are unwilling to use effective contraception - Nursing women - Men who are unwilling to use a condom (even if they have undergone a prior vasectomy) while having intercourse with any woman, while taking the drug, and for 4 weeks after stopping treatment - Other concurrent chemotherapy, immunotherapy, radiotherapy, or any ancillary therapy considered investigational (i.e., utilized for a non-FDA-approved indication and in the context of a research investigation).

NOTE: Patients on therapeutic anticoagulatin should be monitored carefully to maintain therapeutic level of anticoagulation to avoid increased risk of bleeding due to concurrent drug induced thrombocytopenia. It is suggested that patients who require anticoagulation therapy while on therapy use low molecular weight heparin (LMWH). - Major surgery =< 4 weeks prior to registration or have not recovered from side effects of such therapy - Screening ECG with a QTcFredericia (QTcF) > 450 msec
