Pilot Study For Hypothermia Treatment In Hyperammonemic Encephalopathy In Neonates And Very Young Infants

Study Summary

This is a pilot study which will test the safety and feasibility of hypothermia treatment as adjunct therapy to conventional treatment of hyperammonemic encephalopathy (HAE) in neonates versus conventional treatment (dialysis, nutritional therapy, and ammonia scavenging drugs) only. The endpoint of the pilot study will be reached when either 24 patients have been enrolled and no serious adverse events were observed, when no patient has been enrolled in 5 years, or when serious adverse events occur which are clearly linked to the use of hypothermia. These would be serious complications not seen in patients on conventional therapy (dialysis , nutritional therapy, ammonia scavenging drugs) for HAE.

Primary Outcome

The DSMB meets within 3 weeks of each case, no later than 5 weeks after initiation of hypothermia therapy and assesses the safety and feasibility of adjunct hypothermia treatment in this patient group. The treatment of neonates and very young infants in hyperammonemic coma is very complex and adding hypothermia therapy to this treatment could not be feasible, the pilot study therefore also assesses the feasibility of adding hypothermia therapy to the standard of care treatment.
