Prophylaxis With Apixaban in Transplant Eligible Patients With Multiple Myeloma Receiving Induction Therapy With IMiDs
- Registration Number
- NCT04106700
- Lead Sponsor
- Instituto de Investigacion Sanitaria La Fe
- Brief Summary
Interventional, no-randomized, open-label, and single arm multicentre study of apixaban for the prevention of thromboembolic events during induction therapy in transplant-eligible patients with newly diagnosed multiple myeloma who receive bortezomib, thalidomide, and dexamethasone (VTD) during the induction phase of therapy prior to autologous stem cell transplantation (ASCT). The current study is designed to evaluate the efficacy and safety of apixaban during the induction period. Efficacy will be defined as a composite endpoint of acute symptomatic proximal and distal deep venous thrombosis, pulmonary embolism, VTE related deaths, and acute ischemic stroke.
- Detailed Description
This study is designed to test the efficacy and safety of the oral anti factor Xa apixaban 2.5 mg given twice daily as a prophylaxis of VTE in transplant-eligible patients with multiple myeloma during the induction therapy with VTD.
Induction therapy prior to ASCT will consist in no less than 4 and no more than 6 cycles of VTD, depending on treatment response. Duration of each cycle is 4 weeks if there is not any disease or treatment-related complication; therefore, treatment duration will be around 4-6 months. Daily Prophylaxis with apixaban will continue up to a maximum of 14 days after the last dose of thalidomide. In addition, there will be an additional observation period of 14 (± 7) days, starting the day after the last dose of study medication (until 28 days after the end of the last cycle of VTD).

- Primary Outcome Measures
Name Time Method Symptomatic deep-vein thrombosis (DVT) 14 days after last dose of apixaban Lower extremity DVT: erythema (redness of the skin), warmth, pain, swelling, tenderness
Pulmonary embolism (PE) 14 days after last dose of apixaban Pleuritic chest pain, dyspnea (shortness of breath), cough, hemoptysis (expectoration of blood or blood-stained sputum), syncope (fainting), lightheadedness/dizziness, tachypnea (rapid breathing), tachycardia (fast heart rate).
Venous thromboembolism (VTE)- related death 14 days after last dose of apixaban i.e. death for which VTE can not be excluded as a cause
Asymptomatic proximal DVT as detected by systematic compression ultrasound Cycle 6 Day 43 (each cycle is 28 days. Treatment will finish on cycle 4 or 6. Treatment with Apixaban will continue until 14 days after cycle 4/6) Diagnostic assessment of DVT. Presence of any one of the following will be considered diagnostic for the presence of DVT:
1. New or previously undocumented non-compressibility of one or more proximal venous segments (popliteal vein or higher) of the legs on compression ultrasound.
2. Constant intraluminal filing defect(s) in two or more views on contrast venography in one or more venous segments in the legs or pelvis, or involving the inferior vena cava.
