Doxil® + Melphalan + Velcade (DMV) in Relapsed/Refractory Multiple Myeloma

• Status: Terminated
• Trial end date: 2010-01-12
• Target enrollment: 0
• Participant gender: All

Summary

The median overall survival (OS) of relapsed/refractory multiple myeloma (MM) is less than nine months. However, phase II data with the proteasome inhibitor bortezomib (Velcade®) has been heartening, with 35% overall response rates and median survival of 16 months. In-vitro data has shown that this agent dramatically increases the sensitivity to chemotherapeutic agents. Liposomal doxorubicin (Doxil), melphalan, and bortezomib all have different mechanisms of action and toxicity profiles. Clinical studies employing two drug combinations with these agents in patients with refractory MM have found favorable efficacy (nearly no progression of disease) and tolerance data. Thus, the investigators are initiating a phase I/II study to examine the safety and efficacy of combining all three agents into the regimen DMV (Doxil® + melphalan + Velcade).

Alternatively, development of new or worsening of existing lytic bone lesions or soft tissue plasmacytomas, or hypercalcemia (serum calcium >11.5 mg/dL), or relapse from complete response.

Patient Characteristics:

1. 18 yrs or older

2. Patient has given voluntary written informed consent.

3. Unless post-menopausal or surgically sterilized, a female must be willing to use an acceptable method of birth control

4. Male patient must agree to use an acceptable method for contraception for the duration of the study.

5. Eastern Cooperative Oncology Group (ECOG) Performance Status 0-2.

6. Life expectancy is at least 3 months.
