Eliquis (Apixaban) FDA-Approved for DVT and PE Treatment

Stephan Moll, MD writes…  Apixaban (Eliquis®) was approved by the FDA this week (Aug 21, 2014) for the treatment of DVT and PE.  The approval covers (a) acute DVT/PE management and (b) the longer-term prevention of recurrent DVT/PE.

 

Drug Dosing

  • For acute management of VTE: 10 mg taken twice daily for 7 days, followed by 5 mg twice daily. 
  • For secondary prevention of VTE recurrence: 2.5 mg taken twice daily.

 

The Clinical Studies

Approval was based on 2 large clinical  trials, the AMPLIFY [ref 1] and AMPLIFY-EXTENSION [ref 2] trials.  The acute treatment trial (5,244 patients enrolled) showed that apixaban, given immediately upon the diagnosis of new DVT or PE, was as effective as conventional therapy (an injection blood thinner followed by warfarin) and was associated with significantly less major and relevant bleeding.  Thus: Apixaban was as effective as warfarin, but safer.  In the extension trial 2,486 patients received either apixaban or placebo for 12 months after they had completed 6-12 months of standard blood thinner therapy for DVT or PE.  Apixaban reduced the risk of recurrent clots without increasing the rate of major bleeding.

Blood Thinner Choices for Treatment of DVT and PE

Three new oral blood thinners (also referred to as NOACs) are now FDA-approved and available for the treatment of DVT and PE.  A fourth one, edoxaban (Savaysa®), is not available at this time, but is under FDA review.  This Clot Connect document provides a summary table of the pros and cons of the NOACs compared to warfarin, and also a table comparing the 3 available NOACs amongst each other.  The lower risk of major and clinically relevant non-major bleeding makes Eliquis® an attractive choice; the once daily dosing regimen makes Xarelto® an attractive choice.  I do not see any advantage of Pradaxa® over the other two drugs.
