UARK 2003-41: A Study of High-Dose Density Therapy in Patients With Multiple Myeloma

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to find out if treating multiple myeloma (MM) patients with more intense chemotherapy and autologous transplant (high dose density therapy) early in the disease course will result in better treatment outcomes compared to patients treated in the past.

Detailed Description
-----------------
This study will evaluate whether high-dose density treatment during the initial seven months, including tandem transplants within six months after starting therapy, results in superior event-free and overall survival rates as compared to historical controls.

Eligibility Criteria
-----------------
Inclusion Criteria: Patients with symptomatic multiple myeloma, previously treated or untreated. Patients previously untreated must not be eligible for UARK 2003-33. Karnofsky performance score > 60%, unless due to MM Patients must be <75 years of age at the time of registration Patient must not have had a prior auto- or allotransplant Patient must have signed an IRB-approved informed consent and understand the investigational nature of the study. Negative serology for HIV. Baseline studies within 60 days prior to registration; patients must not have a history of chronic obstructive or chronic restrictive pulmonary disease. Patients must have adequate pulmonary function studies > 50% of predicted on mechanical aspects (FEV1, FVC, etc) and diffusion capacity (DLCO) > 50% of predicted. Patients unable to complete pulmonary function tests because of myeloma-related chest pain, must have a high resolution CT scan of the chest and must also have acceptable arterial blood gases defined as P02 greater than 70. Patients with recent (< 6 months) myocardial infarction, unstable angina, difficult to control congestive heart failure, uncontrolled hypertension, or difficult to control cardiac arrhythmias are ineligible. Ejection fraction by ECHO or must be > 40% and must be performed within 60 days prior to registration, unless the patient has received chemotherapy within that period of time (dexamethasone and thalidomide excluded), in which case the LVEF must be repeated. Exclusion Criteria: Uncontrolled infection as defined in protocol section 5.1.11 Liver function abnormalities with total bilirubin more than twice the upper limit of normal or AST or ALT more than three times the upper limit of normal Severe renal dysfunction, defined as a creatinine > 3mg/dl or a creatinine clearance of < 30ml/min Significant neurotoxicity, defined as grade > 2 neurotoxicity per NCI Common Toxicity Criteria Platelet count < 100,000/mm3, or ANC < 1,000/μl POEMS Syndrome Clinically significant hepatic dysfunction as noted by direct bilirubin or AST >3 times the upper normal limit or clinically significant concurrent hepatitis New York Hospital Association (NYHA) Class III or Class IV heart failure Myocardial infarction within the last 6 months Patients with a history of treatment for clinically significant ventricular cardiac arrhythmias Poorly controlled hypertension, diabetes mellitus, or other serious medical illness or psychiatric illness that could potentially interfere with the completion of treatment according to this protocol Pregnant or potential for pregnancy. Women of childbearing potential will have a pregnancy [β-HCG] test at screening, and will be required to use a medically approved contraceptive method. Pregnancy testing will be performed prior to administration of each dose of study drug Breast-feeding women may not participate Prior adriamycin exposure >450 mg/m2
