Carfilzomib, Pomalidomide, and Dexamethasone in Treating Patients With Relapsed or Refractory Multiple Myeloma

Patients receive carfilzomib, pomalidomide, and dexamethasone in 28 days treatment cycles.
Study treatment continues for as long a their myeloma does not worsen and they do not have
unacceptable side effects. After completion of study treatment, patients are followed for up
to 2 years.
