  • Patent number: 9861735
    Abstract: Embodiments of the invention relate to an extracorporeal perfusion apparatus comprising an extracorporeal blood circuit for conveying blood, a filtrate circuit for conveying blood plasma, and a controller, wherein the filtrate circuit is connected to the extracorporeal blood circuit by means of a filter, wherein the filter has a sieving coefficient of 5% for substances having a molar mass of 340,000 g/mol (relative molecular mass of 340 kDa), and wherein a depletion agent comprising a first carrier having a neutral, hydrophobic surface is arranged in the filtrate circuit, wherein the perfusion apparatus comprises a dispensing means for feeding an endotoxin-binding lipopeptide into the extracorporeal blood circuit, wherein the endotoxin-binding lipopeptide is selected from the group consisting of polymyxins, polymyxin derivatives, prodrugs thereof, and a combination thereof.

  • Patent number: 9440019
    Abstract: The invention relates to a sorption agent for removing endotoxins from a biological fluid, comprising a water-insoluble, porous carrier having a neutral hydrophobic surface wherein the surface of the carrier has an adsorptive coating made of polymyxin and albumin, wherein polymyxin and albumin are bonded to the surface of the carrier in a noncovalent manner. The invention further relates to a method for producing such a sorption agent. The sorption agent is used in extracorporeal blood purification, in particular in order to treat individuals, who have sepsis.

  • Publication number: 20150190461
    Abstract: The invention relates to an endotoxin-binding lipopeptide selected from the group consisting of polymyxins, polymyxin derivatives, polymyxin analogues, prodrugs thereof and pharmaceutically acceptable salts thereof, and also relates to a preparation for parenteral administration comprising a lipopeptide of this type, for prophylaxis or for treatment of diseases and conditions caused by endotoxemia, by i) parenterally administering a bolus of the lipopeptide to achieve a lipopeptide serum concentration of 0.01 ?g/ml to 0.8 ?g/ml and ii) maintaining this lipopeptide serum concentration by parenterally administering the lipopeptide over a specifiable period of time.
