Study summary

This study will evaluate the use of the AMICUS device in patients where Therapeutic Plasma Exchange (TPE) is prescribed by their physicians.

Read the detailed description

Therapeutic plasma exchange (TPE) is intended for efficient removal of circulating plasma, with the return of replacement fluids to the patient. In the majority of cases, the treatment goal is to selectively remove the substance directly responsible for the patient's disease process.

Fenwal's AMICUS separator platform is a centrifuge-based apheresis system which collects the blood components of interest and returns the remaining blood components along with saline back to a donor/patient. The device has been cleared for the following:

  • The collection of platelets and plasma in Japan, Europe and the US (BK960005), 1996.
  • The collection of mononuclear cells (MNCs) in the US (BK000047), 2002.
  • The collection of a concurrent red blood cell (cRBC) product collected in ACD-A anticoagulant and stored in ADSOL® Preservation Solution (BK000039), 2002.

Fenwal has developed a new protocol on the AMICUS separator that enables the device to perform TPE procedures. The procedure is similar to the FDA cleared platelet and concurrent plasma collections, except that in TPE procedures the majority of plasma is retained and the red blood cells (RBCs), white blood cells (WBC) and the majority of the platelets are returned to the patient.

Study arms

  • Experimental
    AMICUS Therapeutic plasma exchange, TPE

    Patients are randomized to either TPE on AMICUS or Spectra.

    Device: Therapeutic plasma exchange

  • Active comparator
    Spectra Therapeutic plasma exchange, TPE

    Patients are randomized to either TPE on AMICUS or Spectra.

    Device: Therapeutic plasma exchange

Interventions

What researchers measure

Primary outcomes

  1. Percent Efficiency of Plasma Removal During the Therapeutic Plasma Exchange Procedure

    The calculation is based on the volume of plasma that was processed through the machine compared to the volume of patient plasma that was actually removed during the procedure. Plasma Efficiency = (plasma removed/plasma processed)\*100

    Time frame: After completion of the TPE procedure.

Secondary outcomes

  1. Safety Measured by Adverse Events During the TPE Procedure

    Time frame: Adverse events were collected during each TPE procedure.
