Outcome Measures

Primary Outcomes (1)

  • Actual Fraction of Original Red Blood Cells Remaining to the Target Fraction of Cells Remaining (FCR).

    The primary endpoint will evaluate the mean ratio of the Actual FCR (FCRa) to Target FCR (FCRt) as measured by the patient's Hb S pre-procedure and post-procedure. The predefined mean ratio of the FCRa to FCRt is 0.75 to 1.25.

    Actual FCR will be assessed by taking a pre-procedure sample from the patient on the day of the procedure and a post-procedure sample approximately 10-15 min after procedure completion.

Secondary Outcomes (4)

  • Accuracy of Patient's End Hematocrit as Measured by the Patient's Post-procedure Hematocrit.

    Actual End Hematocrit will be measured by taking a sample from the patient approximately 10-15 min after procedure completion.

  • Subject Cell Loss Post-Procedure (WBC)

    Patient's blood cells will be measured by taking a sample from the patient approximately 10-15 min after procedure completion.

  • Serious Adverse Events

    During the procedure up to 24 hours post-procedure.

  • Subject Cell Loss Post-Procedure (Platelets)

    Patient's blood cells will be measured by taking a sample from the patient approximately 10-15 min after procedure completion.

Study Arms (1)

Amicus Red Cell Exchange in SCD patients

EXPERIMENTAL

Open arm. Patients with sickle cell disease (SCD) treated using one Amicus Red Cell Exchange procedure.

Device: Amicus Red Cell Exchange in SCD patients

Interventions

Each patient will be treated with one RBCx procedure using the AMICUS RBCx System

Also known as: AMICUS RBCx System
Amicus Red Cell Exchange in SCD patients

Eligibility Criteria

Age6 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects with documented diagnosis of a type of sickle cell disorder who require RBC Exchange or RBC Depletion/Exchange treatment.
  • Medically stable subjects who have been previously treated for sickle cell disease with RBC Exchange or RBC Depletion/Exchange.
  • Subjects, or subject's legal representative, who have provided signed informed consent, and assent when applicable, prior to participation.
  • Adequate availability of sickle trait negative, leukoreduced, Blood type (ABO) blood group, Rhesus factor D (Rh (D)) compatible, unexpired replacement RBC products.
  • Subjects with sufficient vascular access to accommodate the RBCx procedure as determined by the medical staff responsible for obtaining intravenous access.
  • Subjects who are able and agree to report adverse events (AEs) during the required reporting period.

You may not qualify if:

  • Procedures that occur during acute hospitalization.
  • Procedures prescribed within one week of discharge of a hospitalization.
  • Subjects with altered mental status that would prohibit the giving and understanding of informed consent, and assent when applicable, who do not have a legally authorized representative.
  • Drug abuse, alcohol abuse, or other factors that in the opinion of the investigator could affect the ability of the subject to comply with the requirements of the protocol.
  • Subjects who have experienced a serious adverse event associated with an RBCx procedure in the past.
  • In the opinion of the investigator, subjects who have a life expectancy fewer than 30 days.
  • Subjects who refuse blood products.
  • Subjects who are pregnant.
  • Subjects who fail to comply with site requirements for cessation of medication that interfere or increase procedure risk.
