NCT01720524
First received: September 17, 2012
Last updated: April 11, 2014

  Purpose

This study will evaluate whether IV sildenafil can reduce the time on inhaled nitric oxide treatment and reduce the failure rate of available treatments for persistent pulmonary hypertension of the newborn.

Drug: placebo
Drug: iv sildenafil
Phase 3

Study Type: Interventional

Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Treatment
Official Title: A Multi-Centre, Randomized, Placebo-Controlled, Double-Blind, Two-Armed, Parallel Group Study To Evaluate Efficacy And Safety Of IV Sildenafil In The Treatment Of Neonates With Persistent Pulmonary Hypertension Of The Newborn (PPHN) Or Hypoxic Respiratory Failure And At Risk For PPHN, With Long Term Follow-Up Investigation Of Developmental Progress 12 And 24 Months After Completion Of Study Treatment

Primary Outcome Measures:
  • Time on inhaled nitric oxide treatment after initiation of iv study drug [ Time Frame: Day 14 or hospital discharge ] [ Designated as safety issue: No ]
  • Treatment failure rate, defined as need for additional treatment targeting persistent pulmonary hypertension of the newborn. [ Time Frame: day 14 or hospital discharge ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Time to final weaning of mechanical ventilation for persistent pulmonary hypertension of the newborn [ Time Frame: Day 14 or hospital discharge ] [ Designated as safety issue: No ]
  • Time from initiation of study drug to treatment failure [ Time Frame: Day 14 or hospital discharge ] [ Designated as safety issue: No ]
  • Change in oxygenation parameters at 6, 12, and 24 hours from baseline [ Time Frame: Day 14 or hospital discharge ] [ Designated as safety issue: No ]
  • Sildenafil plasma concentrations and corresponding PK parameters [ Time Frame: Day 14 or hospital discharge ] [ Designated as safety issue: No ]
  • Safety parameters: incidence and severity of adverse events and abnormal laboratory parameters [ Time Frame: Day 14 or hospital discharge ] [ Designated as safety issue: Yes ]
