About the trial

What the trial wants to find out

This study will use a prospective, open, single-arm design, in which a group of 100 patients with a diagnosis of prolonged COVID, previously selected according to inclusion and exclusion criteria, and who have undergone informed consent process and have signed the informed consent form, undergo two hemoperfusion procedures with the Seraph 100 filter, on consecutive days. They are then evaluated at day 3 and 4 weeks, to complete the safety and effectiveness assessment.

The group in the trial

  • Seraph® 100 Microbind® Affinity Blood Filter (Seraph 100) is a single useTreatment being tested

    The Seraph® 100 Microbind® Affinity Blood Filter (Seraph 100) is a single use, disposable column packed with ultra-high molecular weight polyethylene (UHMWPE) beads. These beads have been modified to contain endpoint-attached heparin on the surface, thus forming a new chemical entity, the polymer now containing material of animal origin (porcine mucosa). The devices are sterilized using a standard ethylene oxide (EtO) cycle, following ISO 11135:2014.
