Lenalidomide in Treating Patients With Progressive or Recurrent Multiple Myeloma After a Donor Stem Cell Transplant

This phase II trial studies how well lenalidomide works in treating patients with progressive or recurrent multiple myeloma after a donor stem cell transplant. Lenalidomide may stop the growth of multiple myeloma by blocking blood flow to the cancer. It may also stimulate the immune system in different ways and stop cancer cells from growing.

PRIMARY OBJECTIVES:

I. To evaluate response of relapsed or progressive multiple myeloma to lenalidomide after allogeneic stem cell transplant.

II. Proportion of patients achieving a complete, partial or minor response.

SECONDARY OBJECTIVES:

I. Evaluate toxicity and tolerability of lenalidomide in this setting.

II. For patients with chronic graft-versus-host disease (GVHD), evaluate the response to lenalidomide.

III. Evaluate time to progression (TTP).

IV. Evaluate overall survival (OS).

OUTLINE:

Patients receive lenalidomide orally (PO) on days 1-21. Courses repeat every 28 days for 2 years or longer in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 3 months thereafter.

Eligibility Criteria:
Inclusion Criteria:

* Relapse is defined as reappearance of monoclonal protein in serum or urine by immunofixation, new or increased bone lesions or hypercalcemia
* Disease progression is define as a 25% increase in monoclonal protein in serum or a 50% increase in 24 hour urinary monoclonal protein from the lowest level attained at any time point after allogeneic transplant or new or increased bone lesions or hypercalcemia
* All previous cancer therapy, including radiation, hormonal therapy and surgery, must have been discontinued at least 4 weeks prior to treatment in this study, excluding corticosteroids for GVHD

Exclusion Criteria:

* Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form
* Pregnant or breast feeding females; (lactating females must agree not to breast feed while taking lenalidomide)
* 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
* Use of any other experimental drug or therapy within 28 days of baseline
