Different Uptravi maintenance doses led to similar outcomes: Study

Differences in Uptravi (selexipag) maintenance doses have no impact on the risk of hospitalization among adults with pulmonary arterial hypertension (PAH), a real-world claims analysis suggests. While different maintenance doses did not affect treatment adherence or discontinuations among U.S. patients in the real world, dose adjustments were more…

PH worsens patient outcomes after hip fracture surgery: Study

People with pulmonary hypertension (PH) see worse outcomes following surgery to correct a hip fracture, a study shows. Among hip fracture patients, PH was associated with higher rates of post-surgical mortality, major in-hospital complications, and hospital re-admissions within three months. Those with severe PH had the worst outcomes after…

FDA tentatively approves generic selexipag as PAH treatment

The U.S. Food & Drug Administration (FDA) has tentatively approved Alembic Pharmaceuticals‘ generic formulation of injectable selexipag as a treatment for pulmonary arterial hypertension (PAH). As a generic drug, which contains the same chemical substance as an approved treatment, it’s equivalent to Uptravi (selexipag) for injection (1,800…

Trial enrollment begins to test long-acting relaxin formula in PH-HFpEF

Enrollment has begun in a Phase 1b study of Tectonic Therapeutic’s TX45, an investigational treatment for people with pulmonary hypertension and heart failure with preserved ejection fraction (PH-HFpEF).

Widening of the pulmonary artery in PH is common: Large-scale study

Pulmonary arterial dilatation — the abnormal widening of the main pulmonary artery leading from the heart — was a common feature among people with pulmonary hypertension (PH) in a large-scale study. The clinical characteristics related to a dilated pulmonary artery, such as heart function and blood flow parameters, varied widely…

Early study of inhaled nitric oxide delivery system doses 1st patient

The goal for the investigational device is to provide patients…

HDL component ApoA-I predicts mortality in PAH: Study

Lower levels of apolipoprotein A-I (ApoA-I), a component of high-density lipoprotein (HDL), or “good cholesterol,” is a significant predictor of mortality in people with pulmonary arterial hypertension (PAH), a study suggests. “Our study identified the significance of ApoA-I as a biomarker for predicting the survival outcome of PAH patients,”…
