The U.S. Food and Drug Administration (FDA) has approved an intravenous form of Uptravi (selexipag) — one infused directly into the bloodstream — for people with pulmonary arterial hypertension (PAH) temporarily unable to take oral medicines. The new intravenous, or IV, formulation is intended to prevent treatment interruptions in adults…

A protein called TIFA is elevated in the blood cells of people with pulmonary arterial hypertension (PAH), suggesting this protein is involved in the biological processes that drive the disease, according to a new study. The findings were published in the journal Scientific Reports, in the study, “…

An upcoming series of educational virtual events for people with pulmonary arterial hypertension (PAH) and their caregivers will offer insights and perspectives about how to manage life with PAH. The National Broadcast Series will include three talks from August to October. Each of the one-hour talks is scheduled to…

Dosing has begun in a clinical trial testing AER-901, Aerami Therapeutics‘ inhaled formulation of imatinib, which is being investigated as a potential treatment for pulmonary arterial hypertension (PAH). “We are pleased to announce that the dosing of subjects in our Phase 1 trial is ongoing and that we expect to…

The U.S. Food and Drug Administration (FDA) has granted orphan drug designation to PT001, an investigational treatment for pulmonary arterial hypertension (PAH). The FDA gives this designation to therapies with the potential to treat rare disorders, defined as those that affect fewer than 200,000 people in the U.S. The designation…

A new metric for assessing cardiac health, called pulmonary artery proportional pulse pressure or PAPP, could help to identify people at high risk of hospitalization or death due to pulmonary hypertension or heart failure, allowing for more timely and effective treatment, a study reported. Researchers at the University of…

Eurordis opened a campaign, called Rare 2030 Action, that is seeking to establish a European action plan for rare diseases to ensure that none of the 30 million people in Europe living with rare diseases are left behind by the start of a new decade. As part of…

Sandoz‘s generic treprostinil injection now is available for subcutaneous (under-the-skin) administration to treat  pulmonary arterial hypertension (PAH), the company announced in a press release. Treprostinil first was approved to treat PAH in the U.S. in 2002. It was developed by United Therapeutics, which markets the…

A new analysis suggests that the doses of rodatristat ethyl — an investigational therapy for pulmonary arterial hypertension (PAH) — now being evaluated in the Phase 2b ELEVATE 2 clinical trial are likely to reduce levels of the hormone serotonin to an extent that has been demonstrated to…

An updated application has been filed with the U.S. Food and Drug Administration (FDA), again asking that LIQ861 be approved as an inhalation treatment of pulmonary arterial hypertension (PAH), its developer Liquidia announced. The company first made this request in an application to the FDA submitted in April 2020. But the…

By screening thousands of potential candidates, researchers have identified a compound, called AG1296, that may be useful for the treatment of pulmonary arterial hypertension (PAH). Their findings were published in the journal Science Translational Medicine, in a study, “iPSC–endothelial cell phenotypic drug screening and in silico…

Activation of a protein called aryl hydrocarbon receptor (AHR) is essential for the development of pulmonary arterial hypertension (PAH), a study found. The findings imply that targeting AHR could be a useful strategy to treat PAH, according to researchers. The results were published in the journal PNAS, in…
