Summary
At the end of this activity, participants should understand:

Multiple myeloma is a cancer of the plasma
cells in the bone marrow dependent upon
signals from the bone marrow microenvironment for growth, survival, and drug
resistance
Summary

Therapy has been dramatically advanced since
the late 1990s, with the introduction of:
– Thalidomide (Thalomid) for multiple myeloma
resistant to conventional therapies
– The proteasome inhibitor bortezomib (Velcade)
– The second-generation immunomodulatory
drug lenalidomide (Revlimid)
Summary

Triple drug therapy is the standard of care in
multiple myeloma, but combinations appear
more effective the earlier in the disease course
they are used

The combination of bortezomib, lenalidomide,
and dexamethasone for newly diagnosed
cases achieved a 100% response rate in one
study with 57% of patients getting a complete
or near complete response
Summary

Saving the better combinations until later in
the disease course may compromise their
efficacy as drug resistance may develop

Maintenance therapy with lenalidomide
improved progression-free survival 60%
compared with placebo in the CALGB trial
100104 and nearly doubled survival without
progression in the IMF 2005-02 trial
Summary

Lenalidomide maintenance therapy was
associated with excess secondary cancers in
the CALGB 100104 and IMF 2005-02 trials,
though the risk-benefit ratio may still favor the
treatment

Genetics may hold the key to biomarkers that
could aid in personalizing drug combinations
for multiple myeloma patients.
