Clinical Trial Summary

RATIONALE: Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as doxorubicin and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) together with bortezomib may kill more cancer cells.

PURPOSE: This phase II trial is studying how well giving bortezomib together with doxorubicin and dexamethasone works in treating patients with multiple myeloma that has relapsed or not responded to treatment.

PATIENT POPULATION: Patients with relapsed or refractory multiple myeloma requiring therapy will be invited to participate in this study. Eligible patients will be >18 years old and able to give fully informed consent. Patients must have a Performance Score (PS) of 0-3 (ECOG), measurable serum and/or urine paraprotein, or serum free light chain, bilirubin value of less than one and a half times the upper limit of normal with ALT/AST values less than two and a half times the upper limit of normal. Patients with non-secretory multiple myeloma are excluded from this study.

Description:

OBJECTIVES:

Primary

• To assess the response (partial and complete response) in patients with relapsed or refractory multiple myeloma receiving bortezomib, doxorubicin hydrochloride, and dexamethasone (PAD) after prior treatment with a maximum of 6 courses of vincristine, doxorubicin, and dexamethasone (VAD) or VAD-like regimen.

Secondary

• To assess the safety and toxicity of PAD therapy in these patients.

• To determine the progression-free survival and overall survival of these patients.

• To compare the original response to VAD with the response obtained with PAD as assessed by percent fall in paraprotein or Bence Jones Protein, lowest level of abnormal protein achieved, and duration of response in these patients.

OUTLINE: This is a multicenter study.

STUDY DESIGN & METHODOLOGY:

This is a non-randomised, open labelled phase II trial in patients with relapsed or refractory multiple myeloma. Patients will be treated with: Bortezomib 1.3mg/m^2 bolus IV injection days 1, 4, 8 & 11 + Dexamethasone 40mg po on days 1, 2, 3, 4 + Doxorubicin 9mg/m^2/day IV continuous infusion over days 1 - 4. In addition, for the first cycle only, Dexamethasone will also be given at 40mg po on days 8 - 11 and 15 - 18.

Each treatment regimen will continue for a minimum of four - and up to six - cycles of 21 days (maximum response and 1 cycle).

This study planned to recruit a total of 69 patients in up to 8 centres in Ireland and the UK.

Patients will be enrolled in three groups of 23 patients:

• Relapsed patients, previously treated with VAD or VAD like regimen (VAMP, C-VAMP and Z-Dex are examples of VAD like therapy) and who have had autologous transplants at least 1 year previously. Patients may proceed directly to PAD therapy or have had a maximum of one other line of therapy before PAD.

• Relapsed patients, previously treated with VAD or VAD-like regimen who have not had autologous transplantation and achieved at least PR (Appendix A). Patients may proceed directly to PAD therapy or have had a maximum of two other lines of therapy before PAD.

• Patients refractory (MR, NC or PD) to VAD or VAD-like therapy. Patients should proceed directly to PAD therapy. Patients with NC or PD may proceed to PAD after a minimum of two cycles of VAD or VAD-like therapy or a minimum of 4 cycles, if MR.

After completion of study treatment, patients are followed every 2 months for 1 year.

14. Previous Bortezomib therapy

15. Patients who have a medical or psychiatric condition which, in the opinion of the investigator, contraindicates the patient's participation in this study

16. Previous or concurrent malignancies at other sites, with the exception of appropriately treated localized epithelial skin or cervical cancer. Patients with remote histories (>5 years) of other cured tumours may be entered

17. Plasma exchange within 21 days of enrolment
