Enrollment Complete for Phase 3 Trial Testing INOpulse for PH

Enrollment is now complete in REBUILD, a Phase 3 clinical trial evaluating INOpulse, an investigational treatment for people with pulmonary fibrosis (PF) who are at risk of developing pulmonary hypertension (PH). According to the therapy’s developer, Bellerophon Therapeutics, the trial’s enrollment was completed earlier than expected. As…

Two Likely Biomarkers for PAH Diagnosis, Progression Identified

Two new biomarkers to assess pulmonary arterial hypertension (PAH) were discovered through large-scale analysis of gene activity profiles using computer software, a study reported. These biomarkers, the activity of the genes PNISR and HNRNPH1, may help diagnose PAH, monitor its progression, or measure responses to therapy. They also may highlight…

Care Center PAH Causes Differ from National Registry, Study Reveals

The identified cause of pulmonary arterial hypertension (PAH) in patients seen at a specialized care center differed substantially from national registry data, a study revealed. Most care center patients were diagnosed with PAH associated with connective tissue disorders and exposure to toxins, whereas idiopathic PAH (IPAH), of unknown cause,…

Study: Ang-2 Blood Test May Predict Treatment Outcomes in CTEPH

A blood test for angiopoietin-2 (Ang-2), a protein associated with forming new blood vessels, may predict treatment outcomes in people with chronic thromboembolic pulmonary hypertension (CTEPH), a study showed. Researchers found that the protein’s level was significantly higher in the bloodstream of patients with this rare form of…

Tissue Oxygenation Measure Predicts PH Outcomes: Study

Mixed venous oxygen tension (PvO2) — a measure for tissue oxygenation — is a significant predictor of outcomes in pulmonary hypertension (PH), a study suggested. Specifically, lower PvO2 was significantly associated with poor outcomes in people with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH),…

Kynurenine Levels Predict Severity, Treatment Response, Survival

Elevated metabolites of the kynurenine pathway in the bloodstream of people with pulmonary arterial hypertension (PAH) when they’re diagnosed predicted disease severity, their response to therapy, and survival, a study discovered. Activation of the kynurenine pathway, related to vitamin B3 production, was found to be linked to…
