NCT04395131

Brief Summary

The study will be a prospective, interventional, non-randomized, single-center study in 20 ESRD patients on hemodialysis. The study will compare performance of the Clearum HS dialyzer to typical values obtained with other commercially available high flux dialyzers. In addition, the Clearum HS dialyzer will be compared to a Fresenius FX80 dialyzer for a baseline (control) comparison. This will be a post-market study. The duration of the trial is 2 weeks for the FX80 control dialyzer + 6 weeks with the Clearum HS dialyzer used for 3x weekly high flux hemodialysis.

Outcome Measures

Primary Outcomes (1)

  • Evaluate performance of small-solute (toxin) removal

    The primary objective of this study is to evaluate performance of small-solute (toxin) removal, represented by urea, under standard high flux hemodialysis conditions with a mean urea reduction ratio (URR) of 65% or greater.

    End of dialysis treatment

Secondary Outcomes (8)

  • Adverse Events

    8 weeks, 3 sessions per week

  • B2M reduction ratio

    5 sampling at mid-week session of week 1, 2, 3, 5 and 8

  • Instantaneous clearance of B2M during specified time-points

    1 sampling at mid-week session of week 7

  • Reduction ratio of albumin during hemodialysis

    5 sampling at mid-week session of week 1, 2, 3, 5 and 8

  • Follow-up of CRP for patients treated with Clearum dialyzer

    Kinetic over 6 week period

  • +3 more secondary outcomes

You may not qualify if:

  • Patients who have acute renal failure with the chance for recovery.
  • Patients who are pre-scheduled for a living kidney transplant within the next two months, who plan a change to PD within the next two months or who require single needle dialysis therapy.
  • Pregnant and lactating women.
  • Patients with a history of positive serology tests for Hepatitis B surface antigen, positive Hepatitis C total antibody, HIV and syphilis.
  • Patients with known hemodynamic instability, anemia (Hgb \< 90 g/L), and/or severe bleeding risks secondary to coagulation disorders.
  • Patients with active or ongoing infection per investigator's judgement.
  • Patients with a history of solid tumors requiring anti-cancer therapy in the past or next 6 months or a life expectancy less than 1 year or patients with a history of a hematology neoplasm.
  • Patients diagnosed with a NYHA Class IV congestive heart failure, or acute coronary syndrome and/or who have suffered a myocardial infarction within three months prior to the start of the study.
  • Patients with a history of severe mental disorders.
  • Patients who are currently participating or have previously participated in another interventional clinical trial in the past 4 weeks.
  • Patients who have had an allergic response to polyarylethersulfone (PAES) or polysulfone membranes or have a history of poor tolerance to dialyzers with synthetic membranes.
  • Patients with advanced liver, heart or pulmonary disease as judged by the Investigator
  • Patients with any comorbidity possibly conflicting with the study purpose or procedures as judged by the Investigator.
