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.

Condition or disease	Intervention/treatment	Phase
Refractory Multiple Myeloma	Drug: azacitidine; Drug: lenalidomide; Drug: dexamethasone; Other: DNA methylation analysis; Other: gene expression analysis; Other: bone marrow aspiration; Other: immunohistochemistry staining method; Other: reverse transcriptase-polymerase chain reaction; Other: flow cytometry	Phase 1; Phase 2

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 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.

Outcome Measures

Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :

1. Phase I: Highest tolerated low dose (HTLD) [ Time Frame: during the first 28-day cycle ]
   azacitidine given at low but increasing doses up to 50mg/m2 twice a week
2. Phase II: Response rate as evidence of progressive or new bone lesions [ Time Frame: after 6 months (cycles) of treatment ]
   Response according to international response criteria (>= PR) and 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.
3. Phase II: Response rate as evidence of progressive or new bone lesions [ Time Frame: after 12 months (cycles) of treatment ]
   Response according to international response criteria (>= PR) and 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.

Secondary Outcome Measures :

1. Progression-free survival [ Time Frame: followed up every 3 months for 3 years. ]
2. Overall survival [ Time Frame: followed up every 3 months for 3 years. ]
3. CD34+ cell yield and time to neutrophil and platelet recovery [ Time Frame: after cycle 1 (28 days) ]
   CD34+ cell yield will be calculated based on flow cytometry of mononuclear cells harvested following stem cell mobilization. Time to neutrophil (> 1,000/mm3) and platelet (> 100,000/mm3) recovery will be counted from the day of stem cell infusion (=day 0)
4. Promoter demethylation and gene reactivation [ Time Frame: within 7 days before treatment start and at the end of cycle #1 ]
   Promoter demethylation and gene reactivation will be measured at least at the HTLD level using the Illumina® HumanMethylation27 BeadChip array on CD138 purified and CD34 purified cells obtained from bone marrow aspirates
5. Changes in global gene expression [ Time Frame: before and after the first cycle of therapy ]
   The RNA harvested from myeloma cells before and after the first cycle of therapy at the HTLD level will furthermore be used to identify changes in global gene expression using the Illumina® HT12 array.
6. Quantify the activity of azacitidine inactivating enzyme cytidine deaminase (CDA) [ Time Frame: at 6 months ]
   Plasma from peripheral blood draws will be used to quantify the activity of CDA using an HPLC method.The enzymatic activity is determined by comparison of cytidine deamination achieved by plasma samples with deamination achieved by incubation of cytidine with dilutions of pure CDA enzyme standards.
