Melphalan and Panobinostat (LBH589) for the Treatment of Patients With Recurrent Multiple Myeloma

Completed · Phase 1/Phase 2

Conditions studied: Multiple Myeloma

In brief

RATIONALE: Drugs used in chemotherapy, such as melphalan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Panobinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving melphalan together with panobinostat may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of melphalan when given together with panobinostat in treating patients with recurrent multiple myeloma.

You may qualify if…

• Diagnosis of multiple myeloma, based on the following criteria:
• Major criteria
• Plasmacytomas on tissue biopsy (1)
• Bone marrow plasmacytosis (> 30% plasma cells) (2)
• Monoclonal immunoglobulin (Ig) spike on serum electrophoresis, IgG > 3.5 g/dL or IgA > 2.0 g/dL, and kappa or lambda light chain excretion > 1 g/day on 24-hour urine protein electrophoresis (3)
• Minor Criteria
• Bone marrow plasmacytosis (10-30% plasma cells) (a)
• Monoclonal immunoglobulin present but of lesser magnitude than given under major criteria (b)
• Lytic bone lesions ©)
• Normal IgM < 50 mg/dL, IgA < 100 mg/dL, or IgG < 600 mg/dL (d)
• Meets any of the following sets of multiple myeloma diagnostic criteria:
• Any two of the major criteria
• Major criterion 1 plus minor criterion b, c, or d
• Major criterion 3 plus minor criterion a or c
• Minor criteria a, b, and c, OR a, b, and d
• Measurable disease, defined as a monoclonal immunoglobulin spike on serum electrophoresis of ≥ 1 g/dL and/or urine monoclonal immunoglobulin spike of ≥ 200 mg/24 hours, or evidence of lytic bone disease
• Must have received ≥ 1 prior treatment regimen OR refractory to most recent chemotherapy
• Relapsed following stabilization or response to standard first-line chemotherapy (e.g., vincristine, doxorubicin hydrochloride, and prednisone or melphalan and prednisone) or first-line high-dose chemotherapy
• Refractory (i.e., failure to achieve at least complete or partial response or stable disease) to most recent chemotherapy, whether or not containing systemic corticosteroids
• Prior treatment with ≤ 4 days of a total of 400 mg of prednisone (or an equivalent potency of another steroid) for myeloma is not considered a regimen
• Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
• Life expectancy > 3 months
• Platelet count ≥ 75 x 10\^9/L (≥ 50 x 10\^9/L if bone marrow is extensively infiltrated)
• Absolute neutrophil count ≥ 1.5 x 10\^9/L (≥ 1.0 x 10\^9/L if bone marrow is extensively infiltrated)
• Aspartate transaminase (AST) and Alanine transaminase (ALT) ≤ 2.5 times upper limit of normal (ULN)

You may not qualify if…

• Plasma cell dyscrasia with polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes (POEMS syndrome)
• Plasma cell leukemia
• Pregnant or nursing females; fertile patients must use effective contraception
• Peripheral neuropathy > grade 2
• Impaired cardiac function or clinically significant cardiac disease (including congenital long QT syndrome, history or presence of sustained ventricular tachyarrhythmia; history of ventricular fibrillation or Torsade de Pointes; bradycardia, defined as heart rate (HR) < 50 beats per minute (bpm) [pacemaker allowed provided HR ≥ 50 bpm]; corrected QT interval > 450 msec on screening ECG; left ventricular ejection fraction below normal on screening ECHO or multigated acquisition (MUGA) scan; right bundle branch block with left anterior hemiblock (bifascicular block); myocardial infarction or unstable angina within the past 6 months; New York Heart Association class III-IV congestive heart failure; uncontrolled hypertension; history of labile hypertension; history of poor compliance with an antihypertensive regimen)

• Prior malignancy within the past 5 years except basal cell or squamous cell carcinoma or carcinoma in situ of the cervix
• Other concurrent severe and/or uncontrolled medical or psychiatric conditions (e.g., uncontrolled diabetes or active or uncontrolled infection), including abnormal laboratory values that could cause unacceptable safety risks or compromise protocol compliance
• Known positivity for HIV or hepatitis B or C
• Severe hypercalcemia (i.e., serum calcium ≥ 14 mg/dL)
• Significant history of non-compliance to medical regimens or unwillingness or inability to comply with instructions given by the study staff
• Concurrent medication that risk prolonging the QT interval or inducing Torsades de Pointes
• Prior panobinostat
• Received chemotherapy, bortezomib, thalidomide, lenalidomide or arsenic trioxide within 3 wks of enrollment (with the exception of nitrosoureas within 6 wks of enrollment)
• Received corticosteroids (>10 mg/day prednisone or equivalent) within three weeks before enrollment.
• Received immunotherapy within < 8 weeks; antibody within < 4 weeks; or radiation therapy to > 30% of marrow-bearing bone within < 2 weeks prior to starting study treatment; or who have not yet recovered from side effects of such therapies.
