A Multicenter, Single-Arm, Open-Label Expanded Access Program for Lenalidomide Plus Dexamethasone in Previously Treated Subjects With Multiple Myeloma

• Status: Completed
• Trial end date: 2009-08-01
• Target enrollment: 0
• Participant gender: All

Summary

This was a multicenter, open-label, single-arm phase 3B study of the combination lenalidomide plus pulse high-dose dexamethasone.

This study (CC-5013-MM-019) was set up and executed primarily as an expanded access program in Germany.

Screening procedures were to take place within 28 days prior to Cycle 1 Day 1 (baseline) with the exception of hematology assessments that were to be performed within 14 days prior to Cycle 1 Day 1. Randomization, blinding, and stratification were not applied in this open-label single-arm study.

Eligible subjects given open-label treatment and received treatment with lenalidomide plus high-dose dexamethasone in 28-day cycles.

Lenalidomide (hard capsules) was to be administered orally (PO) at a dose of 25 mg daily (QD) for the first 21 days of each 28-day cycle. According to the protocol, accrual of subjects to the study was to be terminated within 2 months of commercial availability of lenalidomide for this indication in Germany.

Upon discontinuation from study, minimal information was collected in order to identify when disease progressed.

• Phase: Phase 3

• Must be diagnosed with multiple myeloma that is progressing after at least 2 cycles of anti-myeloma treatment or that has relapsed with progressive disease after treatment.

• Subjects may have been previously treated with thalidomide and/or radiation therapy. In addition, radiation therapy initiated prior to or at baseline (Day 1) may be given concurrently with study therapy, provided that all other eligibility criteria are satisfied.

• Subjects must discontinue all anti-myeloma drug or non-drug therapy prior to the first dose of study drug with the exception of radiation therapy initiated prior to or at baseline (Day 1).

• Measurable levels of myeloma paraprotein in serum (>0.5 g/dL) or urine (>0.2 g excreted in a 24-hour collection sample).

• Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1, or 2.

• Females of childbearing potential (FCBP) must agree to use two reliable forms of contraception simultaneously or to practice complete abstinence from heterosexual intercourse during the following time periods related to this study: 1) for at least 28 days before starting study drug; 2) while participating in the study; and 3) for at least 28 days after discontinuation from the study.

Exclusion Criteria:

• The presence of any of the following will exclude a subject from study enrollment:

• Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form.

• Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study.

• Any of the following laboratory abnormalities:

• Absolute neutrophil count (ANC) <1,000 cells/mm^3 (1.0 x 10^9/L)

• Platelet count <75,000/mm^3 (75 x 109/L) for subjects in whom <50% of the bone marrow nucleated cells are plasma cells.

• Platelet count <30,000/mm^3 (30x10^9/L) for subjects in whom ≥50% of bone marrow nucleated cells are plasma cells.

• Serum SGOT/AST or SGPT/ALT >3.0 x upper limit of normal (ULN)

• Serum total bilirubin >2.0 mg/dL (34 µmol/L)

• Prior history of malignancies other than multiple myeloma (except for basal cell or squamous cell carcinoma of the skin or carcinoma in situ of the cervix or breast) unless the subject has been free of the disease for ≥1 year.

• Prior history of stroke and/or thromboembolic event
