Detailed Description

STUDY DESIGN:

This is a single institution open label, pharmacokinetic validation study of the combination of lenalidomide with dexamethasone for firstline induction therapy in transplant-eligible MM ( Multiple Myeloma ) patients with various degrees of renal failure. There will be 4 patient groups with various degrees of renal function (based on creatinine clearance calculated from a 24 hour urine collection and requirement for dialysis). Each group will receive lenalidomide dosing as per official recommended guidelines:

Group 1 Normal {CrCl(creatinine clearance)>60 mL/min}25 mg (full-dose)-Daily for 21 days of a 28 Day cycle1 Group 2 Moderate renal impairment {30 ≤ CrCl (creatinine clearance) <60 mL/min}10 mg Daily for 21 days of a 28 day cycle Group 3 Severe renal impairment {CrCl (creatinine clearance)<30 mL/min, not requiring dialysis}15 mg Every 48 hours for 21 days of a 28 day cycle (11 PLANNED DOSES EACH 28 DAY CYCLE) Group 4 End-stage renal failure {CrCl (creatinine clearance)<30 mL/min, requiring dialysis}5 mg Once daily for 21 days of a 28 day cycle On dialysis days the dose should be administered following dialysis.

Pharmacokinetic (PK) studies: We will be evaluating PK studies following single and multiple doses of lenalidomide during Cycle 1.Patients will receive their first dose of lenalidomide (Cycle 1, day 1) as per the above designated patient group. PK (pharmacokinetic)sampling for 1st dose only will be drawn at 0, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 24 hours post-dose for group 1 and at 0, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 24, 48, 72 hours for all other groups. The 2nd dose of lenalidomide will be administered on Day 4 for all patients (i.e. no doses on Days 2 and 3). On Day 17 (after 14 doses of lenalidomide administered), repeat PK sampling will be performed at 0, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 24 hours for groups 1, 2 and 4 (before next hemodialysis for those in group 4). Repeat PK sampling for group 3 will be performed at 0, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 24, 48 hours.

Eligibility Criteria

Inclusion Criteria

Patients must fulfill all of the following criteria to be eligible for admission to the study:

1. Understand and voluntarily sign an informed consent form

2. Age≥18 years at the time of signing the informed consent form.

3. Able to adhere to the study visit schedule and other protocol requirements.

4. Previously untreated, symptomatic multiple myeloma as defined by ALL 3 criteria below:

• Monoclonal plasma cells in the bone marrow ≥10% and/or presence of a biopsy-proven plasmacytoma
• Monoclonal protein present in the serum and/or urine
• Myeloma-related organ dysfunction (at least one of the following):

C - Calcium elevation in blood (serum calcium >upper limit of normal) R - Renal insufficiency (serum creatinine >177umol/L) A - Anemia (hemoglobin <100g/L or 20g/L below normal) B - Lytic bone lesions or osteoporosis

5. Eligible for autologous stem cell transplantation as per Princess Margaret Hospital criteria.

6. Disease measurable by serum or urine M (monoclonal) protein, free light chain assay, bone marrow plasmacytosis or plasmacytoma.

7. No prior myeloma therapy (Exception: up to 480 mg of dexamethasone is allowed within the past 28 days, as well as palliative, localized radiation therapy, without the requirement of a washout period prior enrollment).

8. ECOG (Eastern Cooperative Oncology Group) performance status of ≤ 2 at study entry.

9. Laboratory test results within these ranges:

• Absolute neutrophil count ≥ 1,000/mm³
• Platelet count ≥ 50,000/mm³ (untransfused)
• Total bilirubin ≤ 22 umol/L
• Aspartate transaminase (AST) also called serum glutamic oxaloacetic transaminase (SGOT) and Alanine transaminase (ALT) also called serum glutamic pyruvic transaminase (SGPT) ≤ 2 x ULN (upper limit number) or ≤ 5 x ULN if hepatic metastases are present.
• Renal function must be measured by 24hour urine for creatinine clearance (CrCl) - any level of CrCl is allowed for eligibility.

FCBP (Females of childbearing potential) must also agree to ongoing pregnancy testing. Men must agree to use a latex condom during sexual contact with a FCBP even if they have had a successful vasectomy. All patients must be counseled at a minimum of every 28 days about pregnancy precautions and risks of fetal exposure.

Exclusion Criteria

• Patients who fulfill any of the following criteria are not eligible for admission to the study:
