Summary

This trial is testing whether giving more transfusions to premature babies leads to better survival rates and brain development.

Who is the study for?
The TOP trial is for extremely low birth weight infants with a gestational age of 22-28 weeks, admitted to the NICU within 48 hours of life, and weighing less than or equal to 1000 grams. Infants who've had prior transfusions (beyond first 6 hours), received erythropoietin, have congenital conditions affecting survival/neurodevelopment, severe acute conditions, or whose parents cannot attend follow-up are excluded.
What is being tested?
This study tests if higher hemoglobin thresholds in red cell transfusions for very small premature babies can improve survival and neurodevelopment at around two years old. Babies will be randomly assigned to receive either more frequent 'liberal' or less frequent 'restricted' blood transfusions.
What are the potential side effects?
Potential side effects from blood transfusions may include allergic reactions, infections, iron overload in the body, lung injury related to transfusion (TRALI), and immune system complications.

Awards & Highlights

No Placebo-Only Group
All patients enrolled in this study will receive some form of active treatment.
Pivotal Trial
The final step before approval, pivotal trials feature drugs that have already shown basic safety & efficacy.

Trial Design

2Treatment groups
Active Control
Group I: High Threshold TransfusionActive Control1 Intervention
Transfusions will be administered using a higher threshold hemoglobin value.
Group II: Low Threshold TransfusionActive Control1 Intervention
Transfusions will be administered using a lower threshold hemoglobin value. The low threshold values reflect more common practice, so this is considered the 'usual treatment' group
