Panobinostat/Velcade in Multiple Myeloma

Stopped early · Phase 1

Conditions studied: Multiple Myeloma

In brief

Multiple myeloma (MM) accounts for approximately 1% of all malignancies and 10% of hematological tumors, representing the second most frequently occurring hematological malignancy in the United States. At any one time, 50,000 people suffer from MM, and approximately 15,000 are diagnosed each year. The median age is approximately 65 years, although occasionally MM occurs in the second decade of life. Bortezomib and panobinostat intravenous (IV) are active agents in multiple myeloma and appear to work through different biochemical pathways, suggesting that there may be a synergistic effect using the combination. Both compounds have shown anabolic bone effect, which has been associated to significant anti-myeloma activity. Primary objectives: * To assess the toxicity of bortezomib combined with one of 4 doses of panobinostat IV in patients with relapsed/refractory multiple myeloma, and * To find the most appropriate doses of bortezomib and panobinostat IV in the combination. Secondary objective: * To assess the effect of bortezomib in combination with panobinostat IV on inducing osteoblast activation in patients with relapsed/refractory myeloma.

You may not qualify if…

• Prior HDAC, DAC, HSP90 inhibitors or valproic acid for the treatment of cancer
• Patients who have received Velcade within 2 months of enrollment
• Patients who will need valproic acid for any medical condition during the study or within 5 days prior to first panobinostat IV treatment
• Peripheral neuropathy > grade 2.
• Impaired cardiac function or clinically significant cardiac diseases, including any one of the following:
• 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 Novartis 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)
• Other concurrent severe and/or uncontrolled medical conditions (e.g., uncontrolled diabetes or active or uncontrolled infection) including abnormal laboratory values, that could cause unacceptable safety risks or compromise compliance with the protocol
• Patients 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
• Concomitant use of CYP3A4 inhibitors (See Appendix 2)
• Patients who have received targeted agents within 2 weeks or within 5 half-lives of the agent and active metabolites (which ever is longer) and who have not recovered from side effects of those therapies.
• Patients who have received either immunotherapy (e.g. vaccines) within < 8 weeks; chemotherapy 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.
• Patients with an active bleeding tendency or is receiving any treatment with therapeutic doses of sodium warfarin (Coumadin®) or coumadin derivatives. Low doses of Coumadin® (e.g. ≤ 2.0 mg/day) to maintain line patency (if applicable) is allowed.
• Patients who have undergone major surgery ≤ 4 weeks prior to starting study drug or who have not recovered from side effects of such therapy
• Women who are pregnant or breast feeding or women of childbearing potential (WOCBP) not using an effective method of birth control. WOCBP are defined as sexually mature women who have not undergone a hysterectomy or who have not been naturally postmenopausal for at least 12 consecutive months (i.e., who has had menses any time in the preceding 12 consecutive months). Women of childbearing potential must have a negative serum pregnancy test within 24hrs of receiving the first dose of study medication.
• Male patients whose sexual partners are WOCBP not using effective birth control
• Patients with a prior malignancy with in the last 5 years (except for basal or squamous cell carcinoma, or in situ cancer of the cervix)
