Why was Xigris pulled from the market?
FDA Drug Safety Communication: Voluntary market withdrawal of Xigris [drotrecogin alfa (activated)] due to failure to show a survival benefit | FDA.
What happened to Xigris?
Xigris was removed from the worldwide market in October 2011 after PROWESS-SHOCK’s preliminary results were published, so this is all moot of course.
How does drotrecogin alfa work?
Drotrecogin alfa is similar to a natural protein produced by the body (activated protein C). In patients with severe, life-threatening bacterial infections, drotrecogin alfa decreases inflammation and the formation of blood clots in blood vessels. It also increases the breakdown of blood clots.
Is Xigris an antibiotic?
Xigris (drotrecogin alfa) contains no antibacterial preservatives; the intravenous solution should be prepared immediately after reconstitution of the Xigris (drotrecogin alfa) in the vial(s).
What is Xigris used for?
Xigris is a recombinant version of naturally occurring activated protein C. This medication has been approved for the reduction of mortality in adults with severe sepsis (sepsis associated with acute organ dysfunction) who have a high risk of death.
Who made Xigris?
Xigris is the current brand name of activated drotrecogin alfa, manufactured by Eli Lilly. The drug is sold in vials containing either 5 mg or 20 mg, respectively. The United States’ Food and Drug Administration (FDA) approved the drug in 2001 as was the case with the drug authorities in many other countries.
What does Activated Protein C do?
Protein C, also known as autoprothrombin IIA and blood coagulation factor XIX, is a zymogen, the activated form of which plays an important role in regulating anticoagulation, inflammation, and cell death and maintaining the permeability of blood vessel walls in humans and other animals.
How much did Xigris cost?
Xigris was designed to fight sepsis, a condition that kills more than 200,000 Americans annually. It was the only approved drug for sepsis, and it costs $8,000 to treat a single patient.
Did Vioxx test on animals?
Vioxx had tested safe in at least eight studies in African green monkeys and five other animal species. But it later killed an estimated 60,000 Americans and 140,000 persons worldwide from heart attacks and other adverse cardiovascular events. In the year before it was withdrawn, Vioxx earned $2.5 billion for Merck.
Can you donate blood if you have protein C deficiency?
If you have an inherited condition that makes it more likely that you would have a DVT, such as Factor V Leiden or Protein C or Protein S deficiency, and you have not had a DVT, you can give blood. However, if these conditions caused even one DVT, you cannot give blood.

How is Drotrecogin alfa used to treat bacterial infections?
Treating life-threatening bacterial blood infections in certain adults. Drotrecogin alfa is similar to a natural protein produced by the body (activated protein C). In patients with severe, life-threatening bacterial infections, drotrecogin alfa decreases inflammation and the formation of blood clots in blood vessels.
What is the molecular weight of Drotrecogin alfa?
Drotrecogin alfa is activated human protein C that is synthesized by recombinant DNA technology. It is a glycoprotein of approximately 55 kilodalton molecular weight, consisting of a heavy chain and a light chain linked by a disulfide bond.
