FormUlation of bosenTan in pUlmonary arterial hypeRtEnsion (FUTURE) 3 was a 24-week open-label, prospective, and randomized phase 3 study that assessed the pharmacokinetics of bosentan 2 mg/kg b.i.d.

The composite primary end-point was the time to the first morbidity/mortality event, defined as all-cause death, hospitalisation for PAH worsening or intravenous prostanoid initiation, atrial septostomy, lung transplant, or PAH worsening.

In this collaboration, we assess the external validity (or generalisability) of the FPHN ItinérAIR-HTAP predictive equation and the REVEAL risk score calculator. Validation cohorts approximated the eligibility criteria defined for each model.

However, information about its burden in low- and middle-income countries (LMICs) is scant. We thus set out to review both published and unpublished information on the presentation, causes, management, and outcomes of heart failure in LMICs.

We report on the efficacy, safety, disease worsening, survival and prognostic factors in mildly symptomatic pulmonary arterial hypertension (PAH) patients treated with bosentan in the open-label extension phase of the EARLY study.
Methods: Exploratory efficacy outcomes included 6-minute walk distance (6 MWD) and WHO FC.

Background: Epoprostenol sodium with arginine-mannitol excipients (epoprostenol AM; Veletri [Actelion Pharmaceuticals Ltd, Allschwil, Switzerland]) and epoprostenol sodium with glycine-mannitol excipients (epoprostenol GM; Flolan [GlaxoSmithKline, Triangle Park, NC]) are intravenous treatments for pulmonary arterial hypertension (PAH). Epoprostenol AM contains different inactive excipients, resulting in greater stability at room temperature compared with epoprostenol GM.
Methods: In this prospective, multicenter, open-label, randomized, phase IV exploratory study, epoprostenol-naïve patients in need of injectable prostanoid therapy were randomized 2:1 to open-label epoprostenol AM or epoprostenol GM.
Background: Continuous infusion of epoprostenol is the treatment of choice in patients with pulmonary arterial hypertension in functional classes III to IV. However, this treatment's limitations include instability at room temperature. A new epoprostenol formulation offers improved storage conditions and patient convenience.

Methods: A splice variant array-based signature for early detection of Alzheimer's disease (AD) was developed using 315 AD or normal subjects processed in three disparate microarray batches.
Results: A modified top scoring pair classifier using the signature, is robust to batch effects and outperforms other common classifiers, with sensitivity and specificity of 88.
Biomarkers have gained an increased importance in the past years in helping physicians to diagnose Alzheimer's disease (AD). This study was designed to identify a blood-based, transcriptomic signature that can differentiate AD patients from control subjects. The performance of the signature was then evaluated for robustness in an independent blinded sample population.

Proof-of-concept, randomized, double-blind, placebo-controlled, multiple-cross-over n-of-1 study in patients with PD with wearing-off and dyskinesias. Naftazone was titrated up to 120 mg/day during an initial single-blind dose-finding phase.
View Article and Find Full Text PDFTreatment algorithms in pediatric pulmonary arterial hypertension (PAH) are derived from clinical trials in adult populations and from clinical practice, but experience in children is limited. In this retrospective cohort study, we analyzed outcomes in a previously identified cohort of 86 consecutive children with PAH treated with bosentan as part of their treatment regimen. All children with idiopathic PAH or heritable PAH and PAH associated with congenital heart disease or connective tissue disease who started bosentan treatment from May 2001 to April 2003 in 2 tertiary pediatric referral centers were followed, with data collection ending August 2006.
