Study Summary

This trial will test if the drug Viagra® can help repair brain damage in babies suffering from asphyxia at birth, and may provide new solutions for improving their future life.

Who is the study for?
This trial is for newborns with a condition called asphyxia, which can lead to brain damage. They must be at least 36 weeks old at birth, weigh over 1800g, show signs of distress during and after birth, require ventilation, and have evidence of moderate to severe brain issues. Babies with complex heart disease, genetic syndromes, brain malformations or significant bleeding in the brain are not eligible.Check my eligibility
What is being tested?
The trial is testing if sildenafil (Viagra®), known for treating high blood pressure in babies' lungs, can also repair brain damage caused by asphyxia at birth. The study will give sildenafil orally to these babies alongside standard treatments like cooling the body and will check if it improves their brains' and hearts'/lungs' functions.See study design
What are the potential side effects?
While the side effects specific to neonates taking sildenafil are still being studied, potential risks may include low blood pressure reactions or other impacts on cardiovascular function due to its primary use for pulmonary hypertension.

Trial Design

2Treatment groups
Active Control
Placebo Group
Group I: SildenafilActive Control1 Intervention
Sildenafil per os twice a day for seven consecutive days (from day 2 of life to day 9 of life) if brain injury on day 2 of life (dose 1=2mg/kg/dose, dose 2=2.5mg/kg/dose, and doses 3-14=3mg/kg/dose)
Group II: Ora-BlendPlacebo Group1 Intervention
Ora-Blend per os twice a day for seven consecutive days (from day 2 of life to day 9 of life) if brain injury on day 2 of life (dose 1=2mg/kg/dose, dose 2=2.5mg/kg/dose, and doses 3-14=3mg/kg/dose)
