A Study of Thalidomide Plus Dexamethasone (Thal-Dex) Versus DOXIL plusThalidomide Plus Dexamethasone (DOXIL -Thal-Dex) in Patients With Newly Diagnosed Multiple Myeloma
- Conditions
- Multiple Myeloma
- Interventions
- Registration Number
- NCT00097981
- Brief Summary
The purpose of this study is to determine if Thalidomide + Dexamethasone or DOXIL (doxorubicin HCl liposome injection) + Thalidomide + Dexamethasone is more effective in treating newly diagnosed patients with multiple myeloma. The number of patients whose multiple myeloma disappears for a period of time (complete Response) will be studied to make the determination of which treatment is more effective.
- Detailed Description
This is a multi-center, open-label (all people know the identity of the intervention), randomized (the study medication is assigned by chance) study to compare the safety and effectiveness of Thalidomide + Dexamethasone versus DOXIL (doxorubicin HCl liposome injection) + Thalidomide + Dexamethasone in patients with newly diagnosed multiple myeloma. Treatments are administered in 28-day cycles. Patients will receive 4 to 12 treatment cycles, depending on the response of their multiple myeloma to the treatment (measured according to the European Group for Blood and Marrow Transplant Response Criteria). Patients will have additional tests that include Multiple Gated Acquisition (MUGA) scans or echocardiograms to assess the patients for potential cardiotoxicity that could be related to treatment with DOXIL (doxorubicin HCl liposome injection). Maximum duration of study participation for each participant will be 48 weeks.

- Primary Outcome Measures
Name Time Method Complete Response Rate: Number of Participants Who Achieved a Complete Response From Cycle 2 until 28 days following completion of treatment Complete response rate to study medication is defined as number of participants who acheived complete response by the local investigator according to the current European Group for Blood and Marrow Transplantation (EBMT) criteria. According to EBMT criteria, CR is defined as the absence of serum and urine monoclonal paraprotein + plus no increase in size or number of lytic bone lesions. Complete response was assessed at the beginning of every treatment cycle prior to treatment, starting at Cycle 2.
- Secondary Outcome Measures
Name Time Method Overall Response: Number of Participants Who Achieved a Complete Response (CR) or Partial Response (PR) From Cycle 2 until 28 days following completion of treatment Overall response to study medication is defined as number of participants who acheived a complete response (CR) or partial response (PR) by the local investigator according to the current European Group for Blood and Marrow Transplantation (EBMT) criteria. According to EBMT criteria, CR is defined as the absence of serum and urine monoclonal paraprotein + plus no increase in size or number of lytic bone lesions; and PR is defined as not all CR criteria + 50 percentage or more reduction in serum monoclonal paraprotein.
Time to 1st Response From Cycle 2 until 28 days following completion of treatment Time to first response was defined as the interval from date of randomization to date of achieving a partial response (PR) or better according to the current European Group for Blood and Marrow Transplantation (EBMT) criteria. According to EBMT criteria, PR is defined as not all CR criteria + 50 percentage or more reduction in serum monoclonal paraprotein.
Time to Progression From randomization until death or as assessed up to 2 years post last participant last treatment visit Time to progression is the interval between the date of randomization until disease progression or death due to progression.
Overall Survival: Number of Participants Died Due to Any Cause From randomization until death or as assessed up to 2 years post last participant last treatment visit Transplantation: Number of Participants Who Underwent Transplantation (Peripheral Stem Cell / Bone Marrow) From randomization until death or as assessed up to 2 years post last participant last treatment visit Engraftment: Number of Participants Who Underwent Engraftment From randomization until death or as assessed up to 2 years post last participant last treatment visit Engraftment is the process of transplanted stem cells reproducing new cells.
