- Brief Summary
RATIONALE: Drugs used in chemotherapy, such as azacitidine and dexamethasone, work in different ways to stop the growth of cancer cells either by killing the cells or by stopping them from dividing. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. Giving azacitidine together with lenalidomide and dexamethasone may kill more cancer cells.
PURPOSE: This phase I/II trial is studying the side effects and best dose of azacitidine when given together with lenalidomide and low-dose dexamethasone in treating patients with relapsed or refractory multiple myeloma.
- Detailed Description
PRIMARY OBJECTIVES:
Define the highest tolerated low dose (HTLD) and safety of azacitidine given at low but increasing doses up to 50mg/m2 twice a week concurrently with Glomerular filtration rate (GFR)-adjusted lenalidomide and low dose dexamethasone in patients with relapsed or refractory multiple myeloma.
SECONDARY OBJECTIVES:
* Response according to international response criteria (≥PR) and clinical benefit response (≥minor response according to adapted EBMT criteria)
* Correlate response with plasma activity of the azacitidine inactivating enzyme cytidine deaminase (CDA)
* Progression-free survival and overall survival
* Peripheral blood hematopoietic progenitor (CD34+) yield and time to neutrophil and platelet recovery in patients undergoing autologous stem cell transplantation
* Promoter demethylation and gene reactivation in myeloma cells and hematopoietic progenitors treated at the HTLD / HTLD-CKD level after cycle 1
* Changes in global gene expression in myeloma cells treated at the HTLD / HTLD-CKD level after cycle 1
OUTLINE:
This is a phase I, dose-escalation study of azacitidine followed by a phase II study.
Patients receive azacitidine subcutaneously once or twice weekly and oral dexamethasone once weekly starting on day 1. Patients also receive oral lenalidomide once daily on days 1-21. Treatment repeats every 28 days for 6 courses. Patients then continue to receive lenalidomide as maintenance therapy. Treatment continues in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 3 years.

- Primary Outcome Measures
Name Time Method Phase I: Highest Tolerated Low Dose (HTLD) During the first 28-day cycle Azacitidine given at low but increasing doses up to 50mg/m2 twice a week. Maximum tolerated dose reported.
- Secondary Outcome Measures
Name Time Method Overall Survival up to 3 years Overall survival will be measured from study entry to death from any cause - median months survival will be reported
Percent of Participants With Clinical Benefit and Response According to International Response Criteria at 12 months Percent of participants with response according to international response criteria (\>= PR) and percent of participants with clinical benefit response (\>= minor response according to adapted EBMT criteria). Determined with serum and 24 hour urine protein electrophoresis, and as appropriate, supplemented by immunofixation, serum free light chain assay, and bone marrow examination. Response before high dose melphalan and autologous stem cell transplant will also be confirmed by two separate blood and 24 hour urine tests between the last dose of combination therapy and the first dose of the mobilizing agent.
Median Progression-free Survival (PFS) Up to 3 years Median PFS, measured in months from study entry to progression as defined by international response criteria or death of any cause, whichever comes first
