Spectra Optia® Apheresis System
Red Blood Cell Exchange (RBCX)*
Clinical Trial


To evaluate the performance of the Spectra Optia system RBCX protocols (exchange and depletion/exchange) in adults and children with sickle cell disease


Prospective, multi-center, single-arm, open-label study design

Study Population

  • Forty adults (≥ 18 years old) and 20 children (≥ 12 but < 18 years old) were a part of the study
  • Patients were treated chronically with RBCX
  • Patients received a single RBCX either for the initiation of a chronic RBCX program or as a treatment in anticipation of surgery
  • More than 60 percent of patients were prophylactically treated with RBCX as part of their primary or secondary stroke prevention treatment


Primary Endpoint

  • The Spectra Optia system decreased the percentage of hemoglobin S as expected for the amount of replacement red blood cells administered

Secondary Endpoint

  • Post-procedure patient hematocrit was within 1.03 percent (standard deviation of 0.065 percent) of the Spectra Optia system's target

Safety Profile

  • No serious adverse events were reported for 72 investigational subjects
  • Thirteen of 72 subjects (18.1 percent) experienced at least one apheresis-related adverse event
    • Mild to moderate dizziness and nausea were reported most frequently, in 10 of the 13 cases
  • Four subjects experienced a decrease in platelet count following the RBCX procedure but did not require transfusion
  • There was no difference in the types or severity of adverse events reported for the study's adult and pediatric participants
Safety Information


  • No known contraindications for the system's use, except for those associated with all automated apheresis systems
  • The infusion of certain solutions and replacement fluids may be contraindicated in some patients

Possible patient reactions

  • Anxiety, headache, light-headedness, digital and/or facial paresthesia, fever, chills, hematoma, hyperventilation, nausea and vomiting, syncope (fainting), urticaria, hypotension and allergic reactions

Reactions to transfused blood products can include1

  • Fever, circulatory overload, shock, allergic reactions, alloimmunization, graft-versus-host disease and transmission of infection

Restricted to prescription use only

  • Operators must be familiar with the system's operating instructions
  • Procedures must be performed by qualified medical personnel
  • A supervisory practitioner may supervise from a physician office or other nonhospital space that is not officially part of the hospital campus as long as he or she remains immediately available2
