Outcome Measures

Primary Outcomes (4)

• Number of Participants With Success of RBCs in Vivo Recovery After 42-day Storage (Single-label Method)

  The primary outcome of this study is to demonstrate that LR-RBCs collected on the Trima Accel system using non-DEHP disposable tubing sets with AS-3 meet the FDA criteria for 24-hour recovery after 42 days of refrigerated storage in non-DEHP storage bags. The 3 parts of FDA RBC recovery criteria that must be met (below) are presented in Primary Outcome 1 and Primary Outcome 2. The derivation of the sample size was based on the level of precision attained with 26 subjects relative to the 1st part of the criteria. 1. A one-sided lower confidence limit for the proportion of RBC components with 24-hour RBC in vivo recovery less than 75% is 70%\* (Primary Outcome 1), \*Allows for low recoveries (\< 75%) in up to 3 out of 24 to 26 participants 2. A sample mean of in vivo 24-hour RBC percent recovery ≥ 75% (Primary Outcome 2) 3. A sample standard deviation of in vivo 24-hour percent RBC recovery ≤ 9% (Primary Outcome 2)

  43 days

• Number of Participants With Success of RBCs in Vivo Recovery After 42-day Storage (Dual-label Method)

  The primary outcome of this study is to demonstrate that LR-RBCs collected on the Trima Accel system using non-DEHP disposable tubing sets with AS-3 meet the FDA criteria for 24-hour recovery after 42 days of refrigerated storage in non-DEHP storage bags. The 3 parts of FDA RBC recovery criteria that must be met (below) are presented in Primary Outcome 1 and Primary Outcome 2.

Study Arms (1)

Healthy adult participants

EXPERIMENTAL

Performance criteria will be evaluated in healthy adult participants, who receive radiolabeled, autologous infusions of LR-RBC components after being stored for 42 days at 2-6°C.

Device: Trima Accel Auto RBC Collection

Interventions

Trima Accel Auto RBC Collection DEVICE

This is a non-interventional study, observing the in vivo performance of LR-RBC units derived from Trima Accel Auto RBC collection.

Healthy adult participants

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Given written informed consent.
• Age 18 years or older.
• Normal health status as per AABB criteria for healthy donor.
• Able to commit to the study schedule.
• a. Note: Participants who are deferred from volunteer community donations due to certain restrictions may participate in the study, as products are not used for allogeneic transfusion; however, sites may or may not implement this depending on their standard procedures.
• Participants of childbearing potential (either male or female) must agree to use a medically acceptable method of contraception throughout the study.
• Female participants of childbearing potential must agree to take a pregnancy test prior to the apheresis procedure and prior to reinfusion of radiolabeled LR-RBCs.
• Participants must agree to report AEs throughout their participation in the study

You may not qualify if:

• Currently pregnant or nursing females.
• Serum ferritin less than12 ng/mL
• Has previously completed this study with data included in the EAS.
• Participation currently, or within the past 30 days, in another investigational trial that would potentially interfere with the analysis of this investigation (eg, pharmaceutical trial).
• As determined by the Investigator:
• Has been diagnosed with a blood disorder(s) affecting RBC characteristics (eg, Glucose 6 Phosphate Dehydrogenase Deficiency \[G6PD\]),
• Reported history of RBC autoantibodies/autoimmune hemolytic anemia, RBC alloantibodies,
• Clinically significant acute or chronic disease, or
• Reported history of hypersensitivity to technetium or chromium
• Other unspecified reason that, in the opinion of the Investigator, makes the healthy adult volunteer unsuitable for enrollment.
• Treatment with any medication as specified in site deferral list (based on AABB medication deferral list for apheresis donors).
• Previously transfused/reinfused with RBCs within the last 120 days.
