Understanding Maintenance Therapy for Multiple Myeloma
- Once you have been through the first two phases of treatment for multiple myeloma, the next step is called maintenance therapy.
- The term "maintenance therapy" means the treatment is aiming to keep the patient in a state of remission.
- The standard of care for multiple myeloma maintenance therapy is immunotherapy drug lenalidomide (brand name: Revlimid). This drug is also given during the induction therapy phase in combination with other drugs.
Dr. Dickran Kazandjian, a multiple myeloma specialist at the Sylvester Comprehensive Cancer Center in Miami, Fla., has called other terms, such as "induction therapy," for treating myeloma "misnomers." However, he says that maintenance therapy is the only term in multiple myeloma treatment that actually makes sense, as doctors are literally trying to maintain a patient's remission.

"It's rare," he adds. "It's not the rule, but it happens."
What Drugs Should Patients Take During Maintenance Therapy?
Right now, the standard of care for multiple myeloma maintenance therapy is immunotherapy drug lenalidomide (brand name: Revlimid). This drug is also given during the induction therapy phase in combination with other drugs in order to get the deepest remission possible.
With continued treatment with lenalidomide, the maintenance therapy phase has proven effective in keeping multiple myeloma at bay for long stretches of time, as Dr. Kazandjian alluded to.

In Miami, Dr. Kazandjian says he and his colleagues generally agree that lenalidomide is the way to go when it comes to maintenance therapy.
"Most of us at our center (in Miami) believe in still doing lenalidomide maintenance," he says, adding that there is some disagreement among other multiple myeloma specialists when it comes to which drug is the best to use during this treatment phase.
"I think there are some folks (who) believe that giving potentially more maintenance therapies … for high-risk disease may help," he says.
One of those maintenance therapies Dr. Kazandjian speaks of is proteasome inhibitor carfilzomib (brand name: Kyprolis), which is also a drug that is given during the induction therapy phase in combination with other drugs.
"I don't think we're so convinced about that fact."
