PH Seen in More Than Half of Preterm Infants in Dutch Study

More than half of babies born preterm at a center in the Netherlands were found to have pulmonary hypertension (PH), a new study reports. Babies with PH were more likely to develop bronchopulmonary dysplasia (BPD), a breathing disorder where the lungs don’t develop correctly, and survival outcomes were poorer…

Adempas Improves Blood Flow Parameters in PH-HFpEF Trial

Treatment with Adempas (riociguat) improved blood flow measurements in people with pulmonary hypertension and heart failure with preserved ejection fraction (HFpEF) in a clinical trial. Researchers say that further study is needed to determine the effect of Adempas on clinical outcomes like exercise capacity. The study, “…

Virtual Visits Likely Inadequate to Guide Pediatric PAH Care

Diagnostic testing plays an important role in guiding changes in treatment for children with pulmonary arterial hypertension (PAH), suggesting that virtual healthcare visits may not be an adequate substitute for in-person testing for many children with the disease. That’s according to the study, “Factors Determining Change in Treatment for…

PAH Patients Prefer Yutrepia Over Tyvaso in INSPIRE Study

Yutrepia, an inhaled formulation of treprostinil, was generally well tolerated and improved the quality of life for people with pulmonary arterial hypertension (PAH) in the Phase 3 INSPIRE clinical trial. The therapy was preferred by nearly all trial participants who switched to it from Tyvaso, an older inhaled…

Study Gauges Long-term Survival for PAH Patients on Opsumit

More than half of people with pulmonary arterial hypertension (PAH) who start daily treatment with oral Opsumit (macitentan) are expected to still be alive after nine years on the therapy, according to a new analysis of data from the SERAPHIN clinical trial and its open-label extension. “These analyses…

Pre-surgery Risk Assessments in CTEPH Did Not Foresee Outcomes

Among people with chronic thromboembolic pulmonary hypertension (CTEPH), risk assessments and treatment patterns prior to surgical procedures do not predict outcomes after surgery, a new study from Sweden shows. The results suggest that most CTEPH patients who don’t undergo surgery remain in the same risk category for at least…

FDA Approves LungFit PH to Treat Newborns

The U.S. Food and Drug Administration (FDA) has approved LungFit PH, Beyond Air‘s device to administer nitric oxide therapy, to treat persistent pulmonary hypertension of the newborn (PPHN). “The FDA approval of LungFit PH enables a new era of nitric oxide therapy and marks a pivotal event for…

Sotatercept Could Be Effective PAH Treatment, Rodent Models Suggest

Treatment with an analog of sotatercept, Acceleron Pharma’s experimental therapy, eased disease-associated inflammation and changes in blood vessel architecture in multiple rodent models of pulmonary arterial hypertension (PAH), a study reported. The study, “Sotatercept analog suppresses inflammation to reverse experimental pulmonary arterial hypertension,” was published in…

Tyvaso DPI Approved by the FDA for PAH and PH-ILD

The U.S. Food and Drug Administration (FDA) has approved Tyvaso DPI, a dry powder, inhaled formulation of treprostinil, to improve exercise ability in people with pulmonary arterial hypertension (PAH) or pulmonary hypertension associated with interstitial lung disease (PH-ILD). Tyvaso DPI is now the only dry powder inhaler approved…
