Exclusion criteria
Exclusion criteria: Exclusion criteria amended as of 24/08/2007: Registration: 1. Received therapy for their relapsed disease other than local radiotherapy, therapeutic plasma exchange, or dexamethasone up to a maximum of 200 mg. (Radiotherapy since pervious transplant sufficient to alleviate or control pain of local invasion is permitted. Patients who have received hemi-body radiation or similar since previous transplant will not be eligible) 2. ECOG Performance Status 3-4 3. Greater than or equal to Grade 2 peripheral neuropathy within 14 days before registration 4. Known HIV or Hepatitis B/C seropositivity (testing is not required for the trial) 5. Use of any investigational drug within 4 weeks prior to registration, or scheduled to receive any investigational drug during the course of the study 6. Known resistance to combined bortezomib, doxorubicin and dexamethasone (PAD) therapy 7. Known history of allergy contributable to compounds containing boron or mannitol 8. Any medical or psychiatric condition which, in the opinion of the investigator, contraindicates the patient's participation in this study 9. Previous or concurrent malignancies at other sites, with the exception of appropriately treated localised epithelial skin or cervical cancer. Patients with remote histories (>5 years) of other cured tumours may be entered 10. Pregnant or breast feeding 11. Unwilling to use adequate contraception during the study and for 6 months after the end of the study treatment if female of childbearing potential, or male whose partner is a female of childbearing potential unless they are surgically sterile Randomisation: 1. Received any therapy for their relapsed disease, other than local radiotherapy or protocol PAD treatment, prior to randomisation. (Radiotherapy sufficient to alleviate or control pain of local invasion is permitted. Patients who have received hemi-body radiation or similar since previous transplant will not be eligible) 2. Progressive disease, according to International Uniform Response Criteria for myeloma following PAD re-induction therapy or stem cell mobilisation 3. Any contra-indication to protocol treatment that would make the patient ineligible Exclusion criteria provided at time of registration: Registration: 1. Patients who have received therapy for their relapsed disease other than local radiotherapy, therapeutic plasma exchange or dexamethasone up to a maximum of 200 mg 2. Females of child-bearing potential without a negative pregnancy test, immediately prior to the start of PAD therapy and/or unwilling to use barrier contraceptive precautions throughout the study or who are pregnant or breast-feeding 3. Non-secretory MM 4. Performance status three to four (ECOG) 5. Platelet count less than 50 x 10^9/L within 14 days before enrolment 6. Absolute neutrophil count less than 1.0 x 10^9/L within 14 days before enrolment 7. Grade two peripheral neuropathy within 14 days before enrolment 8.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary outcome measures amended as of 24/08/2007: Primary outcome measure is time to disease progression and is defined as time from randomisation to the consolidation part of the trial to first documented evidence of disease progression. Patients who die prior to documentation of disease progression will be censored in the analysis. Central analysis of blood and urine samples (and bone marrow if needed) will by monitored at regular internals (at least post-reinduction treatment, 100 days post autologous stem cell transplant/30 days post-end of cyclophosphamide weekly, annually thereafter and if clinically indicated) to assess response/progression. Disease progression and response rates will be determined according to the International Uniform Response Criteria for multiple myeloma.

Secondary
| Measure | Time frame |
|---|---|
| Secondary outcome measures amended as of 24/08/2007: 1. Response to PAD re-induction treatment will be determined according to the International uniform response criteria for multiple myeloma through central analysis of blood, urine and bone marrow aspirate (if complete response is indicated from local results). 2. Progression-free survival is defined as the time from randomisation to the consolidation part of the trial to first documented evidence of disease progression or death from any cause. Patients who do not progress will be censored at the last date they were known to be alive and progression free. 3. Overall survival is defined as the time from randomisation to the consolidation part of the trial to death from any cause or last follow-up. 4. The feasibility of stem cell collection will be determined by the satisfactory mobilisation of an adequate number of peripheral blood stem cells (greater than 10 CD34+ cells/µl blood) and the subsequent harvest of sufficient numbers of stem cells to support high-dose chemotherapy (greater than 2.0 x 109 CD34+ cells/kg). 5. European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C-30 (EORTC QLQ-C30) and EORTC-myeloma module (EORTC QLQ-MY20), the Leeds Assessment of Neuropathic Symptoms and Signs: Self-complete (LANSS) pain scale and the Brief Pain Inventory (short form) will be used to measure patient-assessed Quality of Life (QoL) and evaluate pain in detail. Questionnaires will be administered at baseline, post re-induction treatment, pre-randomisation (if greater than two weeks since the completion of questionnaires post re-induction treatment), 100 days post-randomisation, 6 months post-randomisation, 1 year post-randomisation and annually thereafter. 6. Toxicity and safety will be reported based on adverse events, as graded by Common Terminology Criteria for Adverse Events (CTCAE V | — |
