Outcome Measures

Primary Outcomes (1)

  • Mean Ratio Actual Fraction of Cells Remaining (FCRa; as Measured by Post-Procedure % HbS) to the Predicted Fraction of Cells Remaining (FCRp; as Predicted by the Spectra Optia System FCR Algorithm Multiplied by the Pre-Procedure % HbS)

    The primary endpoint evaluated the mean ratio of the Actual Fraction of Cells Remaining (FCRa: as measured by Post-Procedure % HbS) to the Predicted Fraction of Cells Remaining (FCRp: as predicted by the Spectra Optia system FCR algorithm multiplied by the Pre-Procedure % HbS), in the evaluable population (60 pts). The pre-defined range for the mean ratio of the FCRa to the FCRp was 0.75 to 1.25.

    Length of the procedure

Secondary Outcomes (3)

  • Procedural Success of the Spectra Optia System in the Evaluable Population

    Length of the procedure

  • Spectra Optia System's Ability to Achieve the Desired Final Hematocrit in the Evaluable Population

    Length of the procedure

  • Device-related Serious Adverse Events (SAE) in the Full Analysis Set

    upon signing consent to 24 hours post-procedure

Study Arms (1)

Red cell exchange in sickle cell

EXPERIMENTAL

Open arm; Red cell blood exchange for patients with sickle cell disease

Device: Red blood cell exchange in sickle cell

Interventions

One Red Blood Cell Exchange using Spectra Optia Apheresis System per enrolled patient

Also known as: Specta Optia Apheresis System
Red cell exchange in sickle cell

Eligibility Criteria

Age12 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • At least 12 years old
  • Enrolled in a program of regular red blood cell exchange (RBCx) to prevent symptoms/complications of sickle cell disease (SCD) or Initiating a program of regular RBCx or Receiving RBCx as a pre-surgical procedure.
  • Medically stable
  • Previous documentation of diagnosis by hemoglobin electrophoresis of a type of sickle cell disorder requiring RBCx.
  • Sufficient vascular access to accommodate the RBCx procedure as determined by the apheresis technician performing the procedure or phlebotomist responsible for obtaining intravenous access.
  • Availability of sickle trait negative, leukoreduced, ABO blood group, Rhesus factor D (Rh (D)) compatible, unexpired replacement blood. See Glossary for definition of replacement blood.
  • Able to commit to the study follow-up schedule.
  • Agree to report adverse events (AEs) during the required reporting period.

You may not qualify if:

  • Inability to obtain informed consent/assent from patient, or permission from parent or guardian.
  • Pregnancy (negative serum pregnancy test required for females of childbearing potential).
  • Life expectancy is fewer than 30 days from time of procedure.
  • Incarcerated or a ward of the court.
  • Refusal of blood products.
  • Failure to comply with site standard requirements for cessation of medications (e.g., angiotensin converting enzyme (ACE) inhibitors) that interfere with or increase risk of RBCx procedures.
  • History of drug or alcohol abuse that, in the opinion of the investigator, could affect the ability of the patient to comply with the study requirements Inability to comply with the protocol in the opinion of the investigator.
