A Phase II Study of the Histone Deacetylase (HDAC) Inhibitor LBH589 (Panobinostat) in Patients With Relapsed or Refractory Non-Hodgkin Lymphoma

Location:

Rochester, Minn., Phoenix/Scottsdale, Ariz.

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

PRIMARY OBJECTIVES: I. To evaluate the proportion of confirmed response of LBH589 in patients with relapsed or refractory non-Hodgkin lymphoma. SECONDARY OBJECTIVES: I. To describe the toxicities associated with LBH589 in patients with NHL. II. To evaluate overall survival, progression-free survival, and duration of response in patients treated with LBH589. TERTIARY OBJECTIVES: I. To evaluate the pharmacokinetics of LBH589. 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 3 times weekly. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 6 months for up to 2 years.

nodal marginal zone B-cell lymphoma; splenic marginal zone B-cell lymphoma; peripheral T cell lymphoma, unspecified; anaplastic large cell lymphoma (T and null cell type); lymphoplasmacytic lymphoma (Waldenstrom Macroglobulinemia); CNS lymphoma; post transplant lymphoproliferative disorders; mycosis fungoides/Sezary syndrome; primary effusion lymphoma; blastic NK-cell lymphoma; adult T-cell leukemia/lymphoma; extranodal NK/T-cell lymphoma, nasal type; enteropathy-type T-cell lymphoma; hepatosplenic T-cell lymphoma; subcutaneous panniculitis-like T-cell lymphoma; angioimmunoblastic T-cell lymphoma; anaplastic large cell lymphoma - primary cutaneous type - For lymphoplasmacytic lymphoma patients without measurable lymphadenopathy, measurable disease can be defined by both of the following criteria: bone marrow lymphoplasmacytosis with > 10% lymphoplasmacytic cells or aggregates, sheets, lymphocytes, plasma cells, or lymphoplasmacytic cells on bone marrow biopsy and quantitative IgM monoclonal protein > 1,000 mg/dL - ANC >= 1000/uL - Hgb >= 9 g/dl - PLT >= 75,000/uL - Total bilirubin =< 1.5 x upper limit of normal (ULN) or if total bilirubin is > 1.5 x ULN the direct bilirubin must be normal - AST =< 3 x ULN - Albumin > 3.0 g/dl - Creatinine =< 2.5 x ULN - Serum potassium, magnesium and phosphorus >= LLN and =< 1.2 x ULN - Total serum calcium [corrected for serum albumin] or ionized calcium >= LLN - Clinically euthyroid; patients are permitted to receive thyroid hormone supplements to treat underlying hypothyroidism - Baseline MUGA or ECHO must demonstrate LVEF >= the lower limit of the institutional normal - Ability to understand and the willingness to sign a written informed consent document - Willingness to return to Mayo Clinic - Life expectancy >= 12 weeks - Willingness to provide blood and tissues samples for research studies as required by the protocol - Negative pregnancy test done =< 7 days prior to registration, for women of childbearing potential only - ECOG performance status (PS) 0, 1 or 2 Exclusion Criteria - Prior HDAC, DAC, HSP90 inhibitors or valproic acid for the treatment of cancer - Patients who will need valproic acid for any medical condition during the study or within 5 days prior to first panobinostat treatment - Candidate for known standard therapy for the patient's disease that is potentially curative - Uncontrolled infection requiring ongoing antibiotics - Any prior therapy for lymphoma within the previous 2 weeks for standard treatments and within 4 weeks for experimental therapies unless the patient has recovered from the nadir of the previous treatment to a level that meets the inclusion criteria - Receiving corticosteroids > 20mg of prednisone per day (or equivalent) - 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 study PI 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 - Screening ECG with a QTcFredericia (QTcF) > 450 msec - Right bundle branch block + left anterior hemiblock (bifascicular block) - Patients with myocardial infarction or unstable angina =< 6 months prior registration - 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 during the study and for 3 months after stopping treatment - 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 3 months after stopping treatment - Other concurrent chemotherapy, immunotherapy, radiotherapy, or any ancillary therapy considered investigational (utilized for a non-FDA-approved indication and in the context of a research investigation); patients should have recovered from any immunotherapy, chemotherapy, or radiation therapy related toxicities - Known positivity for human immunodeficiency virus (HIV) or hepatitis C with uncontrolled disease; baseline testing for HIV and hepatitis C is not required - Active other malignancy requiring treatment that would interfere with the assessments of response of the lymphoma to protocol treatment - Inability to swallow or impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of the drugs (e.g. ulcerative disease, uncontrolled nausea, vomiting, diarrhea > CTCAE Grade 2, malabsorption syndrome or small bowel resection) that would preclude use of oral medications - Thrombolic or embolic events such as a cerebrovascular accident including transient ischemic attacks within the past 6 months - Any severe and/or uncontrolled medical conditions or other conditions that, in the treating physician's opinion, could adversely impact their ability to participate in the study; patients on chronic oxygen therapy, those with liver disease such as cirrhosis, chronic hepatitis or chronic persistent hepatitis, or uncontrolled infections will be excluded - Concomitant use of strong or moderate CYP3A4 inhibitors - Using medications that have a relative risk of prolonging the QT interval or inducing torsade de pointes if treatment cannot be discontinued or switched to a different medication prior to starting study drug - Active bleeding tendency. NOTE: Patients on therapeutic anticoagulation 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 - History of other prior malignancies except for properly treated basal cell or squamous cell carcinoma of skin, in situ cervical cancer, in situ breast cancer or early stage prostate cancer
