Details and patient eligibility


The purpose of this study is to determine efficacy of treatment with bortezomib (in combination with doxorubicin and dexamethasone) in previously untreated patients with Multiple Myeloma.

Full description

This is an open-label, single-arm, multicentre study which will enroll approximately 105 patients. Open-label means all people involved in the study know the identity of the intervention. Single-arm means there is one group of patients, all receiving the same treatment. Four 21-day cycles of a combination of bortezomib i.v. (intravenous) 1.3 mg/m2 (Days 1, 4, 8 and 11), doxorubicin i.v. 20 mg/m2 (days 1 and 4) and dexamethasone p.o. (by mouth) (days 1, 2, 4, 5, 8, 9, 11 and 12) (PAD) will be given. Patients will be discontinued if disease progresses, or unacceptable treatment-related toxicity occurs. Following PAD treatment, patients will have peripheral blood stem cells (PBSC) collected, and an autologous stem cell transplant (ASCT) will be performed. Patients will then make monthly visits to the Study Doctor until 1 year after start of treatment, and attend a final follow-up visit at 2 years. Efficacy assessment of response to PAD will be made using the International Myeloma Working Group (IMWG) criteria. The primary outcome is to compare the overall response rate following 4 cycles of PAD induction therapy between patients with and without extra copies of the long arm of the first chromosome (1q21) measured by fluorescent in situ hybridisation (FISH) in their marrow at baseline. Patient reported outcomes will be assessed using the AQoL (Assessment of Quality of Life). Safety will be evaluated throughout the study by assessment of adverse events including changes in physical examination, concomitant medication, ECOG (Eastern Cooperative Oncology Group) scores, vital signs and clinical laboratory findings. A sample size of 105 provides 80% power (a=0.05) to detect a difference in overall response rate of 28% at the end of 4 cycles of PAD. This is based on the assumptions that 44% of patients have amplification of 1q21 1, 2, the overall response rate with PAD combination therapy is 80%; the overall response rate with PAD if PAD therapy does not overcome 1q21 amplification is assumed to be 64%, while without 1q21 amplification it is assumed to be 92%. That is: Overall Response Rate (ORR) = P1q21 amplified x ORRamplified + P1q21 not amplified x ORRnot amplified i.e. 80% = 44% x 64% + 56% x 92%. The sample size of 105 allows for a 20% drop-out rate. Four 21-day cycles of PAD: a combination of bortezomib i.v. (intravenous) 1.3 mg/m2 (Days 1, 4, 8 and 11), doxorubicin i.v. 20 mg/m2 (days 1 and 4) and dexamethasone p.o. (by mouth) (days 1, 2, 4, 5, 8, 9, 11 and 12).
