Response Adapted Therapy With Bortezomib/Dexamethasone Followed by Addition of Lenalidomide in Non Responders as Initial Treatment for Patients With Multiple Myeloma
Response Adapted Therapy With Bortezomib/Dexamethasone Followed by Addition of Lenalidomide in Non Responders as Initial Treatment for Patients With Multiple Myeloma
The purpose of this study is to see if researchers could get the same good results with less toxicity by using this new approach.
We already know that the three drugs bortezomib, lenalidomide, and dexamethasone given together at the same time are effective. Most physicians therefore treat patients with multiple myeloma with the 3 drug combination. However, the researchers also know that the three drugs given together result in more side effects than when only 2 drugs (bortezomib and dexamethasone or lenalidomide and dexamethasone) are given. The researchers believe that all patients may not necessarily need the three drugs to have good results. In this study, the researchers will first treat your disease with bortezomib and dexamethasone. If the disease is not well controlled with these 2 drugs, only then the third drug, lenalidomide, will be added. By using this sequential approach we may reach the same good results with fewer side effects.
Inclusion Criteria:
Age 18 or greater at the time of signing the informed consent document.
• Patients diagnosed with symptomatic multiple myeloma based on IMWG Diagnostic Criteria. According to these criteria, patient must have
Patients must have symptomatic multiple myeloma without advanced organ damage (such as multiple fractures or advanced bone disease causing immobilization, renal failure, spinal cord compression, or organ compromise due to soft tissue plasmacytoma). If immediate therapy with radiation and high-dose steroids (eg, for spinal cord compression) or if triple therapy is clearly advisable from the start, the patient is not eligible for this trial.
Patients with measurable disease defined as one or more of the following: serum M protein ≥ 1.0 g/dl, urine M-protein ≥ 200 mg/24h, and/or serum FLC assay: involved FLC level ≥ 10 mg/dl with abnormal serum FLC ratio.
Only non transplant candidates or those who opt to forgo ASCT during first line therapy are eligible
ECOG performance status ≤ 2
Female patients must:
Male patients, even if surgically sterilized (ie, status post-vasectomy), must:
Patients must be able to provide voluntary written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care.
Exclusion Criteria:
Participant treated with any prior systemic therapy with the exception of the following:
Presence of Primary or associated amyloidosis (AL)
Participants who plan to proceed with ASCT as part of first line therapy
Poor tolerability or known allergy to lenalidomide, bortezomib and/or dexamethasone or compounds that have similar chemical or biologic composition to these study drugs.
Platelet count < 50,000/mm3 within 21 days of initiation of protocol therapy for patients in whom <50% of bone marrow nucleated cells are plasma cells; or platelet count <30,000/mm3 for patients in whom ≥ 50% of bone marrow nucleated cells are plasma cells. Transfusion is not allowed to meet platelet eligibility criteria.
ANC < 1,000 cells/mm3 within 21 days of initiation of protocol therapy. Growth factor administration is not allowed to meet ANC eligibility criteria.
Hemoglobin < 8 g/dL within 21 days of initiation of protocol therapy. Transfusion may be used to meet hemoglobin eligibility criteria.
Hepatic impairment, defined as bilirubin > 1.5 x institutional upper limit of normal (ULN) Patients with benign hyperbilirubinemia (e.g., Gilbert's syndrome) are eligible or AST (SGOT), or ALT (SGPT), or alkaline phosphatase ≥ to 2 x ULN, within 21 days of initiation of protocol therapy.
Renal insufficiency, defined as creatinine clearance < 30 ml/min within 21 days of initiation of protocol therapy. Creatinine clearance will be the primary eligibility criteria in determining renal insufficiency. The Cockcroft-Gault formula.
Active hepatitis B or C infection
HIV 1 or 2 positivity
Female participant who is pregnant or breast-feeding.
Inability to comply with an anti-thrombotic treatment regimen (e.g., administration of aspirin, enoxaparin, or low molecular weight heparin administration).
Peripheral neuropathy ≥ Grade 2 on clinical examination, within 21 days of initiation of protocol therapy.
Participant who had myocardial infarction within 6 months prior to enrollment or has New York Heart Association (NYHA) Class III or IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities.
Participant who has hypersensitivity to bortezomib, boron, or mannitol.
Serious medical or psychiatric illness likely to interfere with participation in this clinical study.
Participant diagnosed or treated for another malignancy within 2 years of enrollment, with the exception of complete resection of basal cell carcinoma or squamous cell carcinoma of the skin, an in situ malignancy, or low-risk prostate cancer after curative therapy. Patients who have had prior malignancies within the past 2 years but are considered to be "cured" with a low likelihood of recurrence may be eligible at the discretion of the Principal Investigator.
Any other medical condition or laboratory evaluation that, in the treating physician's or principle investigator's opinion, makes the patient unsuitable to participate in this clinical trial.
