  • Change from baseline to end of study (EOS) in systolic blood pressure (SBP) [ Time Frame: From baseline (FUTURE 1) up to 28 days after study treatment discontinuation (EOS or premature study treatment discontinuation) ] [ Designated as safety issue: Yes ]
    The main study objective was to assess the long-term safety and tolerability of bosentan in children with PAH, including changes from baseline in blood pressure.
  • Change from baseline to end of study (EOS) in diastolic blood pressure (DBP) [ Time Frame: From baseline (FUTURE 1) up to 28 days after study treatment discontinuation (EOS or premature study treatment discontinuation) ] [ Designated as safety issue: Yes ]
    The main study objective was to assess the long-term safety and tolerability of bosentan in children with PAH, including changes from baseline in blood pressure.
  • Change from baseline to end of study (EOS) in pulse rate [ Time Frame: From baseline (FUTURE 1) up to 28 days after study treatment discontinuation (EOS or premature study treatment discontinuation) ] [ Designated as safety issue: Yes ]
    The main study objective was to assess the long-term safety and tolerability of bosentan in children with PAH, including changes from baseline in pulse rate.
  • Change from baseline to end of study (EOS) in body weight [ Time Frame: From baseline (FUTURE 1) up to 28 days after study treatment discontinuation (EOS or premature study treatment discontinuation) ] [ Designated as safety issue: Yes ]
    The main study objective was to assess the long-term safety and tolerability of bosentan in children with PAH, including growth as measured by changes from baseline in body weight and height.
  • Change from baseline to end of study (EOS) in height for age. [ Time Frame: From baseline (FUTURE 1) up to 28 days after study treatment discontinuation (EOS or premature study treatment discontinuation) ] [ Designated as safety issue: Yes ]

    The main study objective was to assess the long-term safety and tolerability of bosentan in children with PAH, including growth as measured by changes from baseline in body weight and height.

    For each patient, height was put in the perspective of the height of healthy children of the same age according to the WHO growth standards.

  • Proportion of patients with treatment-emergent liver function abnormalities [ Time Frame: After baseline, up to 1 calendar day after study treatment discontinuation in FUTURE 1 or FUTURE 2 ] [ Designated as safety issue: Yes ]

    The main study objective was to assess the long-term safety and tolerability of bosentan in children with PAH, including laboratory abnormalities related to liver enzymes.

    Proportion of patients with increase in alanine aminotransferase (ALT) or aspartate aminotransferase (AST) above 3 x ULN (upper limit of normal) is reported here.

  • Proportion of patients with treatment-emergent hemoglobin abnormalities [ Time Frame: After baseline, up to 1 calendar day after study treatment discontinuation in FUTURE 1 or FUTURE 2 ] [ Designated as safety issue: Yes ]

    The main study objective was to assess the long-term safety and tolerability of bosentan in children with PAH, including hemoglobin abnormalities.

    Proportion of patients with marked hemoglobin decreases (i.e., decrease of or above 15% of the lower normal limit (LL)) is reported here.

  • Number of subjects with adverse events leading to premature discontinuation of study treatment [ Time Frame: From the first study drug administration in FUTURE 1 ] [ Designated as safety issue: Yes ]
  • 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

Bosentan in Children With Pulmonary Arterial Hypertension Extension Study
An Open Label, Long-term, Safety, and Tolerability Extension Study Using the Pediatric Formulation of Bosentan in the Treatment of Children With Idiopathic or Familial Pulmonary Arterial Hypertension Who Completed FUTURE 1
The main objective of the FUTURE-2 study was to assess the long-term safety and tolerability of the pediatric formulation of bosentan in children with idiopathic pulmonary arterial hypertension or familial pulmonary arterial hypertension who completed FUTURE-1 study.

Interventional
Phase 3
Allocation: Non-Randomized
Endpoint Classification: Safety Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Pulmonary Arterial Hypertension
Drug: Bosentan
32-mg dispersible and breakable tablet. The body weight-adjusted dose of the dispersible tablet was dispersed in a teaspoon of water (not mixed with food) before being administered orally
Other Names:
  • Ro 47-0203
  • Tracleer
Experimental: Bosentan
Bosentan was administered at 4 mg/kg twice daily (b.i.d.) until the end of the study. It could be down-titrated to 2 mg/kg b.i.d. if not well tolerated.
Intervention: Drug: Bosentan
