Phase 3
Conditions
Myeloma
Venous Thromboembolism
Interventions
Registration Number
NCT02066454
Lead Sponsor
University Hospital, Grenoble
Brief Summary

To evaluate:

* the incidence of venous thromboembolic event (VTE)

* the incidence of hemorrhagic complications, In a population of patients with myeloma who are treated with IMiDs and require thromboprophylaxis for 6 months, using an oral anti-Xa anticoagulant, Apixaban, in a preventive scheme, 2.5 mg x2/day

Detailed Description

MYELAXAT trial is multicentre, open trial which aims to evaluate the incidence of venous thromboembolic event (VTE) and the incidence of hemorrhagic complications. All patients with Myeloma treated with iMiDs and require thromboprophylaxis for 6 months, using an oral anti-Xa anticoagulant, Apixaban, in a preventive scheme, 2.5 mg x2/day

    • other antithrombotic treatment : salicylate derivates (aspirin, products containing aspirin), antiplatelet therapy, heparin (unfractionated heparin, low molecular weight heparin, danaparoide sodique, fondaparinux), hirudines, oral anticoagulants (vitamin K antagonists, rivaroxaban, dabigatran)
  • Patient with AST or ALT rate > 3 times upper limit of normal

  • Patient with Bilirubin rate > 1.5 times upper limit of normal

  • Patient with Platelets rate < 75 G/l

  • Patient with Creatinine Clearance (Cockcroft) < 30 ml/mn
