Brief Summary
This is a prospective, randomized, double-blind, controlled study to determine the effectiveness of Mirasol-treated fresh whole blood (FWB) versus Standard-issue FWB for preventing transmission of transfusion-transmitted infections (TTIs). The incidence of pre-defined viral, bacterial, or parasitic TTIs in previously negative participants will be assessed by changes in laboratory findings at multiple time points over the course of the clinical trial.

Outcome Measures
Primary Outcomes (1)
Cumulative incidence of at least one (1) pre-defined TTI
New case of any pre-defined TTIs (HIV, HBV, HCV, HEV, HHV-8, malaria, and/or bacterial infection) in a previously negative patient and matched from the blood donor, indicated by changes in laboratory findings at Day 2, Day 7, Week 4, or Week 10 after the first transfusion.
Up to 10 weeks
Study Arms (2)
Mirasol-treated Fresh Whole Blood
EXPERIMENTALStandard Fresh Whole Blood, treated with Mirasol Pathogen Reduction Technology
Standard Fresh Whole Blood
PLACEBO COMPARATORStandard-issue fresh whole blood
Interventions
Standard issue FWB, which gave negative serological assay results for HIV, HBV, HCV, and syphilis will subsequently be treated with Mirasol PRT, then stored at 1 - 6 degrees Celsius and transfused within 21 days of collection.
Fresh whole blood that gave negative serological assay results for HIV, HBV, HCV, and syphilis will be stored at 1 - 6 degrees Celsius and transfused within 21 days of collection.
Eligibility Criteria
You may qualify if:
- Willing to participate in study and patient or legally authorized representative has given written informed consent (IC)
- Hemoglobin \< 7 g/dL or decision to transfusion by clinical team
- Transfusion necessary based on clinical judgment of attending physician
- Agree to return to the hospital for the follow-up visits
You may not qualify if:
- Presence of red cell alloantibodies
- Incompatible red cell crossmatch
- Not expected to survive for 10 weeks
- Expected to require plasma or platelets within next 10 weeks outside of the FWB provided in the trial
- Blood type AB (due to concern of limited supply)
- Weight \< 30 kg (due to concern for sufficient blood draws to detect bacteria and other TTIs)
- HIV-infected
- Clinical suspicion of sepsis
- Anti-malarial treatment within 7 days prior to randomization
- Fever (central body temperature greater than 38.5°C)
- Transfusion(s) of a blood product within 1 month prior to randomization
- Acute or chronic medical disorder that, in the opinion of the investigator, would impair the ability of the patient to receive protocol treatment
