Why This Trial Is Important

Multiple myeloma is a type of blood cancer that develops in plasma cells. Treatment for multiple myeloma is usually effective in bringing about remission or stopping disease progression, but it rarely provides a cure. Most patients will eventually have a relapse or progression and die from their disease.

Multiple myeloma treatment usually starts with chemotherapy to reduce the amount of disease. This initial treatment, called induction therapy, is often followed by consolidation therapy, which consists of high-dose chemotherapy, single or tandem autologous or allogeneic stem cell transplantation (SCT), or both. Maintenance therapy is then sometimes given in an attempt to prolong the duration of remission.

The addition of the drug lenalidomide (Revlimid; CC-5013) to induction therapy for multiple myeloma has been found to increase both the rate and the duration of remission compared to earlier regimens. In this trial, researchers are exploring whether maintenance therapy with lenalidomide following autologous SCT can slow or prevent the return of cancer. Patients who have had induction therapy will undergo single autologous SCT and then be randomly assigned to receive either maintenance lenalidomide or placebo.

"An earlier clinical trial has shown that maintenance therapy with thalidomide improves survival after autologous SCT in patients with myeloma," said Dr. McCarthy. "However, a high number of patients stopped treatment because of toxicity associated with thalidomide.

"Lenalidomide is a derivative of thalidomide that may be more potent and less toxic, so we have good reason to believe that lenalidomide maintenance therapy may help extend the length of remission in patients who respond to autologous SCT and perhaps help those with partial responses to SCT achieve complete response," Dr. McCarthy said.

"Another exciting aspect of this study is that it demonstrates an important initiative among U.S. researchers to coordinate and collaborate on multiple myeloma clinical trials," he added. "We believe this cooperative effort will improve the efficiency of multiple myeloma trials and ultimately benefit patients by speeding up the development and validation of new treatments."

Glossary Terms

allogeneic stem cell transplantation (A-loh-jeh-NAY-ik stem sel tranz-plan-TAY-shun)
A procedure in which a person receives blood-forming stem cells (cells from which all blood cells develop) from a genetically similar, but not identical, donor. This is often a sister or brother, but could be an unrelated donor.
autologous stem cell transplantation (aw-TAH-luh-gus ... tranz-plan-TAY-shun)
A procedure in which blood-forming stem cells (cells from which all blood cells develop) are removed, stored, and later given back to the same person.
lenalidomide (leh-nah-LIH-doh-mide)
A drug that is similar to thalidomide, and is used to treat multiple myeloma and certain types of anemia. It is also being studied in the treatment of other types of cancer. Lenalidomide belongs to the family of drugs called angiogenesis inhibitors. Also called CC-5013 and Revlimid.
maintenance therapy (MAYN-teh-nunts THAYR-uh-pee)
Treatment that is given to help keep cancer from coming back after it has disappeared following the initial therapy. It may include treatment with drugs, vaccines, or antibodies that kill cancer cells, and it may be given for a long time.
plasma cell (PLAZ-muh sel)
A type of immune cell that makes large amounts of a specific antibody. Plasma cells develop from B cells that have been activated. A plasma cell is a type of white blood cell. Also called plasmacyte.
remission (reh-MIH-shun)
A decrease in or disappearance of signs and symptoms of cancer. In partial remission, some, but not all, signs and symptoms of cancer have disappeared. In complete remission, all signs and symptoms of cancer have disappeared, although cancer still may be in the body.
remission induction therapy (reh-MIH-shun in-DUK-shun THAYR-uh-pee)
Initial treatment with anticancer drugs to decrease the signs or symptoms of cancer or make them disappear.
thalidomide (tha-LIH-doh-MIDE)
A drug that is used to treat multiple myeloma in patients who have just been diagnosed, and a painful skin disease related to leprosy. It is also being studied in the treatment of other types of cancer. Thalidomide belongs to the family of drugs called angiogenesis inhibitors. Also called Thalomid.
