Arsenic Trioxide and Dexamethasone in Treating Patients With Recurrent or Refractory Stage II or Stage III Multiple Myeloma

Status:
Terminated
Trial end date:
2005-01-01
Target enrollment:
0
Participant gender:
All
Summary
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combining arsenic trioxide and dexamethasone in treating patients who have recurrent or refractory stage II or stage III multiple myeloma.
Phase:
Phase 2
