FCBP must also agree to ongoing pregnancy testing. Men must agree to use a latex condom during sexual contact with females of child bearing potential even if they have had a successful vasectomy. - Able to take aspirin daily as prophylactic anticoagulation (patients intolerant to ASA may use warfarin or low molecular weight heparin). - Life expectancy ≥ 3 months - Subjects must meet the following laboratory parameters: - Absolute neutrophil count (ANC) ≥1000 cells/mm3 (1.0 x 109/L) - Platelets count ≥ 75,000/mm3 (75 x 109/L) - Serum SGOT/AST <3.0 x upper limits of normal (ULN) - Serum SGPT/ALT <3.0 x upper limits of normal (ULN) - Serum creatinine <2.5 mg/dL (221 µmol/L) - Serum total bilirubin <2.0 mg/dL (34 µmol/L) Exclusion Criteria: - Patients with non-secretory MM (no measurable monoclonal protein, free light chains, and/or M-spike in blood or urine). - Prior history of other malignancies (except for basal cell or squamous cell carcinoma of the skin or carcinoma in situ of the cervix or breast) unless disease free for ≥ 5 years. - Myocardial infarction within 6 months prior to enrollment , or NYHA(New York Hospital Association) Class III or IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmias, electrocardiographic evidence of acute ischemia or active conduction system abnormalities. - Pregnant or lactating females are ineligible. - Given the potential of the study drugs to trigger or worsen HIV viremia and the incidence of opportunistic infections inpatients infected with the HIV virus, HIV-1 or HIV-2 positive patients will be excluded. The interactions of HAART with study drugs have not been determined. - Active hepatitis B or hepatitis C infection. - Active viral or bacterial infections or any coexisting medical problem that would significantly increase the risks of this treatment program. - Any coexisting medical problem or laboratory evaluation that, in the treating physician's or principal investigator's opinion, makes the patient unsuitable to participate in this clinical trial. - Known hypersensitivity to dexamethasone, lenalidomide, or thalidomide. - History of thromboembolic event within the past 6 months prior to enrollment.
|Official title||A Phase II Study of Dexamethasone (DECADRON®), Thalidomide (THALOMID®), and Lenalidomide (REVLIMID®) for Subjects With Relapsed or Refractory Multiple Myeloma|
|Principal investigator||Ruben Niesvizky, MD|
|Description||This phase II study is a treatment program for patients with relapsed or refractory multiple myeloma who have had prior treatment with both thalidomide and lenalidomide in separate regimens each used as a single agent or in combination with corticosteroids. Up to 45 patients will be enrolled. Patients who sign informed consent form and RevAssist® and S.T.E.P.S® patient agreement form and fulfill all eligibility criteria will be enrolled. DexTR therapy: Cycles 1-4 - Dexamethasone (40mg ) will be given on days 1-4, 9-12, 17-20 of a 28-day cycle. - Thalidomide will be given 50mg daily on days 1-7, thereafter 100mg daily on days 8-28 of the first 28-day cycle. Thalidomide will then be given at 100mg/daily for days 1-28 of each subsequent cycle. - Lenalidomide will be given 25mg daily for days 1-21 of each 28 day cycle. - Prophylactic medications, such as medications for thrombosis risk, will be given. After completing 4 cycles: - Patients who demonstrate disease progression at any time will be taken off study. - Patients who achieve a resolution of monoclonal gammopathy as detected on serum immunofixation or achieve a plateau of disease (no change in M-spike as detected on serum protein electrophoresis) for > 2 cycles will be transitioned to maintenance therapy. - Patients who continue to respond without achieving either a plateau or a CR will continue on induction therapy until plateau for >2 cycles or CR in the absence of untoward toxicity. These patients will be then transitioned to maintenance therapy. Maintenance therapy: Maintenance therapy will consist of: - Dexamethasone 20mg weekly days 1, 8, 15, 22 out of a 28 day cycle) - Lenalidomide 25 mg/daily days 1 - 21 out of a 28 day cycle. 15mg/daily on days 1-21 of a 28 day cycle of lenalidomide will be given to patients with a creatinine clearance of < 40cc/min* - Patients who finished induction therapy with DexTR at a reduced dose of lenalidomide will start maintenance therapy at the same dose of lenalidomide on which they ended induction therapy. For patients with a creatinine clearance of < 40cc / minute, the lenalidomide dose will be the lower of their last induction therapy dose or 15mg daily on days 1 - 21 out of a 28 day cycle. Serial clinic visits and laboratory measurements will be performed to monitor for treatment response. Those patients who demonstrate progression of disease at any point during DexTR therapy will be taken off study. At the end of every cycle (which may coincide with day 1 of the new cycle), response and toxicity will be evaluated. During cycle 1, patients will have lab work done weekly (CBC with differential and blood electrolytes). All patients will remain on study until disease progression or side effects become excessive. Patients who achieve a stable plateau and are on maintenance therapy as defined above may be taken off study if eligible to proceed to high dose chemotherapy and autologous stem cell transplantation.|
