- Patient Information:
Details with Side Effects
Xigris (drotrecogin alfa (activated)) is a recombinant form of human activated protein C. An established human cell line possessing the complementary DNA for the inactive human protein C zymogen secretes the protein into the fermentation medium. Fermentation is carried out in a nutrient medium containing the antibiotic geneticin sulfate. Geneticin sulfate is not detectable in the final product. Human protein C is enzymatically activated by cleavage with thrombin and subsequently purified.
Drotrecogin alfa (activated) is a serine protease with the same amino acid sequence as human plasma-derived activated protein C. Drotrecogin alfa (activated) is a glycoprotein of approximately 55 kilodalton molecular weight, consisting of a heavy chain and a light chain linked by a disulfide bond. Drotrecogin alfa (activated) and human plasma-derived activated protein C have the same sites of glycosylation, although some differences in the glycosylation structures exist.
Xigris (drotrecogin alfa) is supplied as a sterile, lyophilized, white to off-white powder for intravenous infusion. The 5 and 20 mg vials of Xigris contain 5.3 mg and 20.8 mg of drotrecogin alfa (activated), respectively. The 5 and 20 mg vials of Xigris (drotrecogin alfa) also contain 40.3 and 158.1 mg of sodium chloride, 10.9 and 42.9 mg of sodium citrate, and 31.8 and 124.9 mg of sucrose, respectively.
