Randomized Trial of Lenalidomide, Bortezomib, Dexamethasone vs High-Dose Treatment With SCT in MM Patients up to Age 65
Purpose
In this research study, we are looking to explore the drug combination, lenalidomide, bortezomib and dexamethasone alone or when combined with autologous stem cell transplantation to see what side effects it may have and how well it works for treatment of newly diagnosed multiple myeloma. Specifically, the objective of this trial is to determine if, in the era of novel drugs, high dose therapy (HDT) is still necessary in the initial management of multiple myeloma in younger patients. In this study, HDT as compared to conventional dose treatment would be considered superior if it significantly prolongs progression-free survival by at least 9 months or more, recognizing that particular subgroups may benefit more compared to others.

Patients with benign hyperbilirubinemia are eligible. - Renal insufficiency (serum creatinine >2.0 mg/dl or creatinine clearance <50 ml/min, within 21 days of registration) - Respiratory compromise (DLCO < 50%) - Clinical signs of heart or coronary failure or LVEF < 40%. Myocardial infarction within 6 months prior to enrollment, NYHA Class III or IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conductive system abnormalities - Intercurrent illness including, but not limited to ongoing or active severe infection, known infection with hepatitis B or C virus, poorly controlled diabetes, severe uncontrolled psychiatric disorder or psychiatric illness/social situations that would limit compliance with study requirements - Previous history of another malignant condition except for basal cell carcinoma and stage I cervical cancer. If malignancy was experienced more than 2 years ago and confirmed as cured, these participants may be considered for the study on case by case basis with PI discussion. - Inability to comply with an anti-thrombotic treatment regimen - Peripheral neuropathy >/= Grade 2

Experimental RVD Alone |
All participants received one cycle of Lenalidomide (R), bortezomib (V) and dexamethasone (D) and then were randomized. All participants then received two additional RVD cycles, followed by stem-cell collection. RVD Alone participants received five additional RVD cycles. Maintenance in both arms comprised daily lenalidomide 10 mg, escalated to 15 mg if tolerated, until disease progression, unacceptable toxicity, or withdrawal from treatment or study. After finishing protocol-specified treatment, off-study salvage transplantation was recommended but not mandated for RVD Alone participants at relapse. RVD cycle duration=21 days R: 25 mg oral on days 1-14 V: 1.3 mg per square meter of body surface area IV or subcutaneous on days 1, 4, 8, and 11 D: 20 mg oral (cycles 1-3) or 10 mg (cycles 4-8) on days 1, 2, 4, 5, 8, 9, 11, and 12 |

Active Comparator RVD plus ASCT |
All participants received one cycle of Lenalidomide (R), bortezomib (V) and dexamethasone (d) and then were randomized. All participants then received two additional RVD cycles, followed by stem-cell collection. RVD plus autologous stem cell transplant (ASCT) participants received high-dose melphalan (200 mg/m2, adjusted for ideal body weight) ASCT and, upon recovery (~day 60), two additional RVD cycles. Maintenance in both arms comprised daily lenalidomide 10 mg, escalated to 15 mg if tolerated, until disease progression, unacceptable toxicity, or withdrawal from treatment or study. After finishing protocol-specified treatment, RVD plus ASCT participants could undergo a second transplant. RVD cycle duration=21 days R: 25 mg oral on days 1-14 V: 1.3 mg per square meter of body surface area IV or subcutaneous on days 1, 4, 8, and 11 D: 20 mg oral (cycles 1-3) or 10 mg (cycles 4-8) on days 1, 2, 4, 5, 8, 9, 11, and 12 |

Detailed Description
The drugs, lenalidomide, bortezomib, and dexamethasone, are approved by the FDA. They have not been approved in the combination for multiple myeloma or any other type of cancer. Bortezomib is currently approved by the FDA for the treatment of multiple myeloma. Lenalidomide is approved for use with dexamethasone for patients with multiple myeloma who have received at least one prior therapy and for the treatment of certain types of myelodysplastic syndrome (another type of cancer affecting the blood). Dexamethasone is commonly used, either alone, or in combination with other drugs, to treat multiple myeloma. Please note that Bortezomib and Lenalidomide are provided to patients participating in this trial at no charge. Melphalan and cyclophosphamide, the drugs used during stem cell collection and transplant, are also approved by the FDA. Melphalan is an FDA-approved chemotherapy for multiple myeloma and is used as a high-dose conditioning treatment prior to stem cell transplantation. Cyclophosphamide is used, either alone, or in combination with other drugs, to treat multiple myeloma. These drugs have been used in other multiple myeloma studies and information from those studies suggests that this combination of therapy may help to treat newly diagnosed multiple myeloma. After screening procedures determine if a patient is eligible for this research study, the patient will be randomized into one of the study groups: lenalidomide, bortezomib and dexamethasone without autologous stem cell transplantation, followed by lenalidomide maintenance (Arm A) or lenalidomide, bortezomib and dexamethasone with autologous stem cell transplantation, followed by lenalidomide maintenance (Arm B). There is an equal chance of being placed in either group. Randomization was stratified by International Staging System (ISS) disease stage (I, II, or III) and cytogenetics (high-risk [presence of 17p deletion, t(4;14), or t(14;16) on fluorescence in-situ hybridization], standard-risk [absence of high-risk abnormalities], or undetermined [test failure]) assessed locally in a screening bone marrow sample, with positivity cut-offs per institutional standards.
