Diaphragm neurostimulation eases PH during mechanical ventilation

Lungpacer Medical’s AeroNova diaphragm neurostimulation system significantly reduced pulmonary hypertension (PH) among critically ill patients with lung failure while they were on mechanical ventilation, according to data from the STIMULUS trial. The device, which electrically stimulates nerves to activate the diaphragm muscles in synchrony with mechanical ventilation, also…

GLS1 immune blockade reduces PAH indications in rat model

Blocking GLS1, an enzyme that drives pro-inflammatory immune macrophages, reduces the signs and symptoms of pulmonary arterial hypertension (PAH) in rats, a study reports. “This study offers a fresh outlook upon understanding the role of macrophages in PAH and provides experimental evidence in developing targeted therapeutic strategies,” the researchers…

Right heart size differs between men and women with PAH: Study

Men with pulmonary arterial hypertension (PAH) have a larger right heart size and worse survival rates than women, independent of body size and functional status, a study reports. Moreover, sex-specific mortality risk thresholds, with higher risk indicated by a larger area of the right pulmonary artery, as measured by…

Winrevair regimen balances efficacy, safety in PAH: Analysis

The dosing regimen for Winrevair (sotatercept-csrk) is optimal for balancing efficacy and safety in adults with pulmonary arterial hypertension (PAH), an analysis of clinical trial data shows. This regimen is “well-justified based on the totality of the observed safety and efficacy data from Phase 2 and Phase 3…

CS1 expanded access program for PAH now covers 10 patients

Cereno Scientific said it has enrolled nine additional people with pulmonary arterial hypertension (PAH) in its expanded access program (EAP) for investigational therapy CS1, bringing the total number of patients in the program to 10. The patients will continue receiving CS1 after completing a Phase 2a clinical trial.

LungFit PH receives European CE mark approval to treat newborns

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…

Cereno secures loan financing to continue developing CS1 for PAH

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…

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…
