Armetheon, Inc., is a privately held San Francisco Bay area based clinical stage biopharmaceutical company
focused on the development of novel drugs for highly
unmet need in cardiovascular diseases. The company was founded by three successful biotech entrepreneurs and
pharmaceutical executives with several years of drug R&D and
company building experience.
Armetheon’s late-clinical stage oral anticoagulant addresses a major unmet need:
- Oral anticoagulants (or blood thinners) are one of the most commonly prescribed class of drugs and
tecarfarin, if approved, could be the first oral anticoagulant in modern medical history that could be labeled
for all indications for anticoagulation.
- Despite introduction several years ago, the newly approved oral anticoagulants that target thrombin or
Factor Xa have not displaced warfarin as the no. 1 prescribed oral anticoagulant. Unlike tecarfarin, lack
of an antidote and inability to monitor are major disadvantages of these newer agents which work thru different
mechanism of action.
- In addition, these newly approved agents can’t be used in patients with prosthetic heart valves (especially
mechanical heart valves) as per March 2014 American College of Cardiology/American Heart Association guidelines
as well as having contraindication or not-recommended warnings on the labels granted by FDA and the European
- There is high interest from both regulatory authorities and the medical community for a safer and better
drug to replace warfarin, because it is the no. 1 reason for hospitalization due to adverse and fatal drug
- Vitamin K antagonist (VKA) class of oral anticoagulants where warfarin is the dominant drug will remain an
important class of drugs for chronic oral anticoagulation.
- The new VKA tecarfarin solves majority of the problems associated with warfarin and so, upon approval, it
is anticipated to become the best-in-class for all patients requiring chronic oral anticoagulation in
particular for those patients with prosthetic heart valves where there is no alternative but warfarin. Previous
clinical and non-clinical studies suggest a superior profile of tecarfarin compared to warfarin.
- Tecarfarin is a potential blockbuster drug candidate in the major therapeutic areas of cardiovascular
disease and thrombosis at a time when there is a shortage of late stage products in the pipelines of major
Potentially best-in-class, late clinical trial stage orally active anticoagulant. It is a potent
inhibitor of VKOR that is not metabolized by CYP2C9 enzyme. Unlike, non-monitored oral
anticoagulant drugs that are direct inhibitors of thrombin or Factor Xa, tecarfarin, is being
developed for use in patients with (i) prosthetic heart valves, and/or (ii) who have renal
