Limitations and caveats
The study was uncontrolled and exploratory. The main purpose of exceptional use treatment period of FUTURE 3 extension was to provide participants with bosentan beyond 12-month treatment period of FUTURE 3 extension. Providing bosentan as a study treatment required monitoring safety on an individual participant-level. No formal hypothesis was formulated, therefore results were exploratory.

Registered outcomes17

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryTreatment Emergent Adverse Events (AEs) up to 7 Days After Permanent Study Drug DiscontinuationUp to 62 weeks in average
This is the total number of subjects with at least one adverse event (serious or not serious) whether or not causally related to the study drug and presented cumulatively in the FUTURE 3 and FUTURE 3 Extension study. NOTE: FUTURE 3 extension study was exploratory and no primary efficacy and safety endpoints were defined in the protocol. So, this safety outcome measure was selected and reported as primary endpoint here.
OtherChange From Baseline up to 12 Months of Study Treatment in the World Health Organization Functional Classification (WHO FC)At Month 12
The WHO FC indicates the severity of Pulmonary Arterial Hypertension: class I (none) to class IV (most severe). Changes from baseline to month 12 and month 18 of treatment with bosentan included: improvement (change from a higher to a lower FC), worsening (change from a lower to a higher FC) or no change/stable (same FC at baseline and at the post-baseline time point). Baseline was defined as the last valid assessment performed prior to first study drug intake in the FUTURE 3 core study.
OtherChange From Baseline up to 18 Months of Study Treatment in the World Health Organization Functional Classification (WHO FC)At Month 18
The WHO FC indicates the severity of Pulmonary Arterial Hypertension: class I (none) to class IV (most severe). Changes from baseline to month 12 and month 18 of treatment with bosentan included: improvement (change from a higher to a lower FC), worsening (change from a lower to a higher FC) or no change/stable (same FC at baseline and at the post-baseline time point). Baseline was defined as the last valid assessment performed prior to first study drug intake in the FUTURE 3 core study.
OtherChange From Baseline up to 12 Months of Study Treatment in the Global Clinical Impression Scale (GCIS)At Month 12
The GCIS is a scale used to rate the patient's current overall clinical condition ("Very Good", "Good", "Neither Good or Bad", "Bad", and "Very Bad"). Rating was performed independently by the physician and parents or legal representatives. Baseline was defined as the last valid assessment performed prior to first study drug intake in the FUTURE 3 core study.
OtherChange From Baseline up to 18 Months of Study Treatment in the Global Clinical Impression Scale (GCIS)At Month 18
The GCIS is a scale used to rate the patient's current overall clinical condition ("Very Good", "Good", "Neither Good or Bad", "Bad", and "Very Bad"). Rating was performed independently by the physician and parents or legal representatives. Baseline was defined as the last valid assessment performed prior to first study drug intake in the FUTURE 3 core study.
OtherNumber of Patients With Pulmonary Arterial Hypertension (PAH) Worsening Components up to the Last Day of Treatment + 7 DaysUp to 62 weeks in average
Number of patients with at least one PAH-worsening component (death, lung transplant, hospitalization due to PAH progression, initiation of new therapy for PAH, new/worsening right heart failure) reported cumulatively over FUTURE 3 core and extension study.
OtherPulmonary Arterial Hypertension (PAH) Progression up to End of Treatment + 7 DaysFrom baseline to Month 18
PAH progression was defined by time elapsed from the first study drug administration in the FUTURE core study to the day of the first occurrence of any of the following PAH worsening events: death, lung transplant, hospitalization due to PAH progression, initiation of new therapy for PAH or new / worsening right heart failure. Subjects without a PAH worsening event were censored at EOT + 7 days. PAH progression was estimated by Kaplan-Meier methodology and expressed by the percentage of participants free of events at different time points.
OtherOverall SurvivalFrom baseline to month 18
Overall survival was defined as the time elapsed between the first study drug administration and death (any cause) up to end of study (Month 18 survival follow-up), regardless of whether the patient was on study treatment. Patients who died, regardless of the cause of death, were considered to have had an event. Patients last known to have been alive were censored on their date of last contact. Percentage of participants without death at different time points was estimated using Kaplan-Meier methodology.
OtherExceptional Use Treatment Period (EUTP): Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) up to 7 Days After Permanent Discontinuation of Study DrugUp to 7 days after discontinuation of study drug (up to 3 years and 4 months)
An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. TEAEs are defined as AEs with onset during the treatment period or that are a consequence of a pre-existing condition that has worsened since baseline.
OtherEUTP: Percentage of Participants With Treatment-emergent Serious Adverse Events (SAEs) up to 7 Days After Permanent Discontinuation of Study DrugUp to 7 days after discontinuation of study drug (up to 3 years and 4 months)
An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. TEAE are defined as AEs with onset during the treatment period or that are a consequence of a pre-existing condition that has worsened since baseline. A SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.

Exceptional-use set included all patients who entered the EUTP. Due to change in study conduct, patients treated with bosentan t.i.d. switched to b.i.d. after local Amendment B to global protocol version 2 (17 March 2015 for Belarus and Ukraine, 1 April 2015 for China) and displaying summaries in the EUTP period by dose were not significant. Therefore, the results were reported combined for bosentan b.i.d./t.i.d.
