RNA Molecule FGF21 May Be Therapeutic Target

The blood levels of a signaling molecule called fibroblast growth factor 21 (FGF21) are significantly reduced in people with high-altitude pulmonary hypertension (PH) and in mice with hypoxia-induced PH, a study shows. Hypoxia refers to low oxygen conditions and chronic hypoxia is a common cause of PH. Also, treatment with…

Vascular Progenitor Cells’ Receptor Protein May Be New PAH Target

A receptor protein at the surface of lung vascular progenitor cells regulates the cells’ growth and maturation into smooth muscle cells, contributing to the vascular remodeling that characterizes pulmonary arterial hypertension (PAH), a study shows. Suppressing this protein — called platelet-derived growth factor receptor alpha (PDGFR-alpha) — prevents these progenitor…

Ferrer Will Market Tyvaso for PH-ILD in More Countries

Ferrer has acquired exclusive rights to commercialize Tyvaso (inhaled treprostinil) for the treatment of pulmonary hypertension associated with interstitial lung disease (PH-ILD) outside North America, Japan, China, and Israel. The therapy, developed by United Therapeutics, is currently approved for that indication only in the U.S.,…

CTEPH Study Ties Lung Arterial Obstruction to Airflow Obstruction

Increased lung arterial obstruction is significantly associated with greater airflow obstruction in people with chronic thromboembolic pulmonary hypertension (CTEPH) and without a smoking history, a study shows. Notably, airflow obstruction, reflected by a reduced ability to exhale quickly, was lessened with reduced arterial obstruction and improved blood flow following…

Aerami Therapeutics Goes Public Through SPAC Merger

Aerami Therapeutics, a biopharmaceutical company focused on developing inhaled therapies for severe respiratory diseases — including pulmonary arterial hypertension (PAH) — has entered into a merger agreement with FoxWayne Enterprises Acquisition, a special purpose acquisition company (SPAC). The goal of this merger is to accelerate the development of…

Patterns in HRCT Lung Scans May Predict Survival Rates in IPAH

The presence of specific patterns called centrilobular ground-glass opacifications (cGGOs) in high-resolution computed tomography (HRCT) lung scans is associated with a two-year higher risk of death in people with idiopathic pulmonary arterial hypertension (IPAH), according to a small study in Poland. These findings suggest that chest HRCT data could…
