Brief summary: 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.

Detailed description: This will be a prospective, open-label, single-arm, pilot study, in which a group of 100 PC patients will undergo two hemoperfusion procedures, to verify the safety and preliminary efficacy of the Seraph 100 device. Eligible patients will be invited to participate and once they sign the Informed Consent (IC) they will undergo two hemoperfusion procedures, on consecutive days, of -4 hours duration each time, using a multicomponent apheresis machine with the Seraph 100 filter. Patients will be followed for a total of 30 days, to monitor the presence of AEs (safety) and possible changes in clinical outcomes (preliminary efficacy).
