Brief Summary:
Around the time of birth, some babies experience a condition called asphyxia, which means that their brain and other organs do not receive enough blood and/or oxygen to work properly. This life-threatening condition accounts for nearly 1 out of 4 deaths of all babies around the world, and often leads to severe brain damage, cerebral palsy, epilepsy, and trouble with learning and functioning in everyday life. At this time, no treatment is available to repair the brain damage caused by asphyxia. Excitingly, a drug called sildenafil (Viagra®) is already given safely to babies who suffer from increased blood pressure in their lungs' vessels. Recent studies using a laboratory model of asphyxia at birth suggest that sildenafil may also repair the brain damage caused by asphyxia. Similarly, recent small studies have shown that it is both feasible and safe to give sildenafil to human babies, who suffered from asphyxia at birth. These studies also highlight the first promising signs that sildenafil may improve how the brains of these babies work, which is consistent with the abovementioned laboratory studies.
On the basis of these previous researches, the investigators predict that sildenafil can repair the damage to a baby's brain. The investigators will test whether sildenafil can be safely given to a large group of human babies who suffer from asphyxia at birth, and will confirm whether sildenafil improves or not how their brains and hearts/lungs work.
This project will enable to determine whether sildenafil is a promising treatment for repairing brain damage in babies who suffer from asphyxia at birth. This project may also provide new solutions for these babies to improve their future life.

Detailed Description:
The investigators will enroll neonates with HIE treated with TH from NICUs in a multicentre, randomized, double-blind, placebo-controlled phase 2 clinical trial to evaluate the safety and efficacy of sildenafil to repair brain injury. Neonates with moderate-severe HIE on admission and with brain injury on a day-2 brain MRI (during TH) will be randomized to sildenafil or placebo (allocation 2:1) for 7 consecutive days.
Aim 1: Evaluate the efficacy of sildenafil to improve brain injury (primary outcome). The investigators will determine whether sildenafil reduces brain injury on a day-30 MRI compared to the baseline day-2 MRI.
Aim 2: Determine the safety of sildenafil (secondary outcome). The investigators will assess the safety of sildenafil by recording the incidence of adverse events.
Aim 3: Evaluate the efficacy of sildenafil to improve cardiopulmonary hemodynamics (secondary outcome). The investigators will determine whether sildenafil improves pulmonary pressure and right/left ventricular function on day 4 of life (after TH completion) compared to baseline day-2 measurements
