This document summarizes the results of a phase 3 clinical trial comparing the efficacy and safety of DVd (pegylated liposomal doxorubicin, vincristine, dexamethasone) versus VAd (doxorubicin, vincristine, dexamethasone) as first-line therapy for multiple myeloma. The trial found that DVd and VAd had comparable response rates, progression-free survival and overall survival. DVd had advantages of less neutropenia, alopecia, cardiac toxicity and fewer hospital visits, while having more hand-foot syndrome. DVd also had benefits of more convenient outpatient administration.

Final results from a phase III randomized study comparing DVd with VAd in first-line multiple myeloma.
1. Final Results: Multicenter Trial
of DVd vs VAd in Newly

2. Study Rationale
• VAD widely used as first-line therapy:
- Rapid response; 50%-80% response rate
- Efficacious cytoreductive therapy prior to stem
cell transplantation
• Decreased popularity due to:
- Inconvenience of 96-h doxorubicin/vincristine
continuous infusion
- Toxicity: neutropenia, cardiac, alopecia

3. Replacing Conventional
Doxorubicin with DOXIL
Changing VAd to DVd
DOXIL
(Pegylated liposomal doxorubicin)
• Longer half-life (>55 hours) Polyethylene
- Once monthly dosing that glycol
mimics continuous infusion
• Improves safety
- Less neutropenia
- Less alopecia
Liposome
- Lower risk of cardiac toxicity
Conventional
doxorubicin 3

4. Study Rationale
• Phase II Study of DVd (N = 33)*
- Lower dexamethasone dose
- Response rate
• 88% (12% CR, 76% PR)
• Median TTP, 23.1 months
• 3-year survival: 67%
- Safety
• Hand-foot syndrome: Grade 3/4 (18% / 3%)
• Neutropenia: Grade 3/4 (21% / 9%)
• Mucositis: Grade 3 (12%)
