About

This research study is being done to see if combining the investigational chemotherapy drug, MEDI-551 with the known anti-myeloma drugs, Lenalidomide and Dexamethasone will reduce your myeloma cancer stem cells.

Full description

To explore the effect of Lenalidomide, dexamethasone and Medi-551 on multiple myeloma cancer stem cells (CSCs). Myeloma CSCs will be assessed by a clonogenic assay from the bone marrow and flow cytometry from peripheral blood.

Enrollment: 20 patients

Sex: All

Ages: 18 to 100 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Age 18 to 100 years at the time screening

Exclusion criteria

• Any condition that, in the opinion of the investigator, would interfere with evaluation of the investigational product or interpretation of patient safety or study results.
• Concurrent enrollment in another clinical study, except for non-interventional, observational studies.

• Active hepatitis B as defined by seropositivity for hepatitis B surface antigen. Or patients with positive hepatitis B core antibody titers.
• Patients with hepatitis C antibody will be eligible provided that they do not have elevated liver transaminases or other evidence of active hepatitis.
• Documented current central nervous system involvement by multiple myeloma.
• Previous medical history or evidence of an intercurrent illness that may, in the opinion of the investigator, compromise the safety of the patient in the study.
• Diagnosis of plasma cell leukemia
• Diagnosis of POEMS syndrome
• Diagnosis of Amyloidosis
• Diagnosis of non-secretory myeloma

Lenalidomide, Dexamethasone, and MEDI-551

Experimental group

Description:

Eligible patients will receive Lenalidomide and dexamethasone as per standard of care guidelines for 2 cycles. Patients with a clinical response to lenalidomide and dexamethasone after 2 cycles will proceed to get MEDI-551 for 2 cycles. MEDI-551 will be dosed at 4mg/kg IV on days 1 and 8 of cycle 3 and 4mg/kg IV on day 1 of cycle 4.
