About

To evaluate changes in coagulation (blood clotting) factors and platelet function in multiple myeloma participants undergoing VELCADE treatment for the first time.

Full description

Cardiovascular complications during the treatment of patients with multiple myeloma are not uncommon, (10%) and the frequency clearly increases with the use of regimens containing thalidomide in combination with glucocorticosteroids or chemotherapy especially adriamycin. Even with prophylactic anticoagulation, DVT still occurs in 10% of such patients. The use of full anticoagulation raises considerable concern of bleeding especially during the post chemotherapy thrombocytopenic period. We observed no thromboembolic episodes when Velcade was added to thalidomide and adriamycin containing chemotherapy.

Therefore, we would like to investigate this protective antithrombotic effect of VELCADE in a malignancy associated with a hypercoagulable state in a group of 10 patients with Relapsed/Refractory Multiple Myeloma.

Enrollment: 11 patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Patients with myeloma who had relapsed after one prior treatment and who have demonstrated resistance to their last treatment, who are candidate to receive Velcade and had normal PT and PTT, will be evaluated for inclusion in the present study.

Exclusion criteria

• Previous history of venous thromboembolism, myocardial infarction, stroke, TIA
• Hypercoagulable state (deficit ATIII, Factor V Leiden, deficit protein S, deficit protein C, prothrombin gene mutation), antiphospholipid syndrome.
• Von Willebrand disease, inherited platelet abnormalities.
• Familiar history of hypercoagulable state.
• Anticoagulant therapy, aspirin, non-steroidal anti-inflammatory drugs, beta blockers, tricyclic antidepressant, hormone replacement therapy, BCPs, and all other agents able to interfere with platelet function in the previous two weeks.
• Non-secretory MM, unless the patient has measurable lesions on CT, MRI and/or PET.

Trial design

11 participants in 1 patient group

Velcade

Experimental group

Description:

Treatment on this study will last 2 cycles. Each cycle consists of 3 weeks, or 21 days. After you have gone off study, you will be followed every three months for approximately 2 years. Each cycle will consist of 3 weeks (21 days) according to the schedule below. DRUG ROUTE DOSE DAYS Velcade IV 1.3 mg/m2 1,4,8, and 11 This 21-day period will be considered one treatment cycle; Cycle 2 would commence on Day 22 (Cycle 2, Day 1). Patients may continue to receive treatment every 21 days, provided there is no evidence of disease progression or no unacceptable toxicity for a two cycles.
