NCT02918851

Brief Summary

This is a single-center, randomized, partially blinded study to determine whether 42-day old red blood cells (RBCs) deliver oxygen as effectively as 7-day old RBCs and also to determine whether transfusion with 28-day old RBCs is non-inferior to 7-day old RBCs with respect to oxygen delivery. In this study, subjects will be randomized to be transfused with 2 units of autologous (one's own) RBCs that are either 7-, 28-, or 42-days old. Endpoints include changes in exercise duration and VO2 max (test of oxygen consumption/delivery) between groups.

Outcome Measures

Primary Outcomes (1)

  • Percent Change From Baseline in Maximal Oxygen Uptake (VO2 Max) After Blood Cell Transfusion

    Percent Change From Baseline in Maximal Oxygen Uptake (VO2 Max) on Day 2 After Blood Cell Transfusion

    Baseline (prior to receiving blood) and Day 2 after receiving blood

Secondary Outcomes (1)

  • Percent Change in Duration of Exercise From Baseline to Day 2 After RBC Transfusion

    Baseline and Day 2 after transfusion

Study Arms (3)

7-day old RBCs

EXPERIMENTAL

Transfusion of 7-day stored red blood cells: Subjects will be transfused with their own 7-day old red blood cells

Biological: Transfusion of 7-day stored red blood cells

28-day old RBCs

EXPERIMENTAL

Transfusion of 28-day stored red blood cells: Subjects will be transfused with their own 28-day old red blood cells

Biological: Transfusion of 28-day stored red blood cells

42-day old RBCs

EXPERIMENTAL

Transfusion of 42-day stored red blood cells: Subjects will be transfused with their own 42-day old red blood cells

Biological: Transfusion of 42-day stored red blood cells

Interventions

Subjects will donate blood at Week 0 and Week 5 of their participation and receive, at Week 6, back a transfusion of their Week 5 (7-day old) red blood cells.

7-day old RBCs

Subjects will donate blood at Week 2 and Week 5 of their participation and receive, at Week 6, back a transfusion of their Week 2 (28-day old) red blood cells.

28-day old RBCs

Subjects will donate blood at Week 0 and Week 5 of their participation and receive, at Week 6, back a transfusion of their Week0 (42-day old) red blood cells.

42-day old RBCs

Eligibility Criteria

Age18 Years - 40 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Habitual exerciser defined as ≥ 30 minutes of at least moderate or high intensity exercise ≥ 3 times per week. After consent, and at the subsequent screening visit, a VO2 max test will be performed, and subjects with a low value (\< 35 mL/kg/min) will be excluded (screen failure). Based on our previous experience, we anticipate that \<10% of the subjects will fall into this category
  • Calculated total blood volume (TBV) ≥4,500 mL using an established formula:
  • Men: (0.006012 x H3) + (14.6 x W) + 604 = TBV
  • Women: (0.005835 x H3) + (15 x W) + 183 = TBV \[H=height in inches; W=weight in pounds\]
  • Has access to transportation to visit the blood collection facility and to return to Stony Brook for all study visits.

You may not qualify if:

  • Any significant acute or chronic medical illness or problem, including, but not limited to, diabetes, hypertension, cardiac disease, asthma, chronic obstructive lung disease
  • Current or recent (last 60 days) tobacco or nicotine use
  • History of sickle cell trait or disease or any other acquired or hereditary hematological abnormality
  • History of fainting or other significant adverse reaction during phlebotomy or donation of blood
  • Known prolonged corrected QT interval (or evidence of such at screening) on electrocardiogram defined as \>470 ms
  • Known or suspected illicit drug or alcohol abuse
  • Known or suspected HIV, Hepatitis B, or Hepatitis C infection
  • History of thrombophilia or anticoagulant therapy
  • Pregnancy
  • Obesity defined as BMI\>30
  • Recent history of blood donation: a) Single whole blood unit donation within the past 8 weeks; b) Double RBC donation by apheresis within the past 16 weeks; or c) Plasma donation by apheresis within the past 4 weeks
  • Inadequate RBC mass based on TBV \<4500 ml (above) or screening Hb \<14 g/dL
