Design outcomes

Primary

MeasureTime frame
Main Objective: To assess the long-term safety and tolerability of the pediatric formulation of bosentan in children with IPAH or familial PAH. The primary endpoint analysis will be the analysis of tolerability and safety endpoints: · Treatment-emergent adverse events up to 24 hours after permanent discontinuation of study drug. · Adverse events leading to premature discontinuation of study drug. · Serious adverse events up to 28 days after permanent discontinuation of study drug. · Changes from baseline to Study End in vital signs, body weight, and height. · Treatment-emergent marked laboratory abnormalities. ; Secondary Objective: Exploratory efficacy endpoints: · Change from Baseline in FUTURE 1 to Study End or Premature study drug discontinuation (FUTURE 1 or 2) in: - WHO functional class - Quality of life questionnaire (SF-10 for childrenTM) - Global Clinical Impression scale according to the parents/legal representatives - Global Clinical Impression scale according to the physician · From Baseline in FUTURE 1, time to worsening of PAH, defined as death or transplantation or hospitalization for PAH worsening. · From Baseline in FUTURE 1, time to worsening of PAH or initiation of new therapy for PAH or new right heart failure or worsening of right heart failure. ;Primary end point(s): In addition to long-term tolerability and safety information, the FUTURE 2 study will provide an opportunity to assess quality of life and functional status of the paediatric population using the new formulation.
