Lung tissue and cells from the blood vessels that pass through the lungs derived from people with pulmonary arterial hypertension (PAH) produced fewer vitamin D receptors (VDRs) than normal, a study shows. Treating PAH patient-derived blood vessel cells with calcitriol, the active form of vitamin D, reduced VDR deficiency…

LungFit PH, Beyond Air’s device for administering nitric oxide therapy, has received European CE mark approval for persistent pulmonary hypertension in newborns (PPHN). This approval allows the company to market the device in the European Union and all other countries that recognize this certification, and also extends its…

Winrevair (sotatercept-csrk) significantly reduced the risk of all-cause death, a lung transplant, or hospitalization among adults with pulmonary arterial hypertension (PAH) at a high risk of dying enrolled in a Phase 3 clinical trial. These top-line findings in the ongoing ZENITH trial (NCT04896008), testing the Merck…

Cereno Scientific has secured loan financing to continue developing CS1, its lead therapeutic candidate for pulmonary arterial hypertension (PAH). The funds, totaling at least 250 million Swedish crowns (nearly $23 million), will help the company reach its milestones into 2026. This includes the U.S. Food and Drug Administration…

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…

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…

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…

A SIRT3 protein deficiency in skeletal muscles, which are attached to bones, was related to pulmonary hypertension associated with heart failure with preserved ejection fraction (PH-HFpEF), a study shows. A lack of SIRT3 triggered the release of LOXL2, a protein that promotes lung tissue scarring, which stimulated the CNPY2…

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). TX45 is a long-acting formulation of relaxin, a protein involved in reproduction and cardiovascular function. It has anti-fibrotic, or anti-scarring,…

Third Pole Therapeutics said it has successfully completed an early feasibility study of its portable inhaled nitric oxide (iNO) delivery device, eNOfit, allowing the company to move to larger trials for pulmonary hypertension (PH) associated with interstitial lung disease. eNOfit is designed to provide patients with mobile treatment…

Note: This story was updated Jan. 30, 2024, to correct the approved indications of available treprostinil formulations. The U.S. Food and Drug Administration (FDA) has delayed its decision to extend the use of Yutrepia — Liquidia‘s inhaled dry powder formulation of treprostinil — to people with…

A protein known as MCJ might be a target of treatments needed to preserve heart function in people with pulmonary hypertension (PH), a study reports. Elevated levels of MCJ were found in the lung tissue of individuals affected by the low oxygen conditions of chronic obstructive pulmonary disease…
