This study focused on some of the sickest pulmonary arterial hypertension patients – those with advanced disease who were already on the best available treatments but still faced a high risk of dying within the next year. For these patients, doctors have traditionally had limited options. Researchers enrolled 172 high-risk patients who were already receiving […]
TPIP is a new version of an existing pulmonary arterial hypertension medication called treprostinil. It is designed as a “prodrug” – meaning it becomes active only after the body processes it. The key advantage is that TPIP can be taken as a dry powder in a capsule-based inhaler, once daily. In a 102-patient phase 2b
Patients with pulmonary hypertension are classified according to clinical criteria to inform treatment decisions. Knowledge of the molecular drivers of pulmonary hypertension might better inform treatment choice, say researchers involved in a study published in May in the American Journal of Respiratory and Critical Care Medicine. The researchers studied blood samples from 470 people who
Selexipag is an oral selective IP prostacyclin receptor agonist. This study, presented during an oral session at the International Society for Heart and Lung Transplant (ISHLT) congress on April 29, 2025, provides the longest follow-up data available for any pulmonary arterial hypertension therapy, tracking 574 patients originally randomized to selexipag in the GRIPHON trial, with
The investigational drug CS1 aims to reverse the pathological vascular remodeling of the small pulmonary arteries. A successful Phase IIa trial was concluded in 2024 (see our article here). Insights into the long-term use of CS1 are being gathered in an expanded access program with 10 patients from the Phase IIa trial. Preparations are currently
Imperial College London is working with Apollo Therapeutics to develop a prospective monoclonal antibody treatment for pulmonary arterial hypertension (PAH). The potential treatment is based on a protein that was identified in original research by the university, and is currently undergoing a proof of concept trial at Hammersmith Hospital, part of Imperial College Healthcare NHS Trust. To
Sleep difficulties are commonly reported by individuals living with pulmonary hypertension (PH); however, there is limited research examining their impact. In other chronic health conditions, sleep problems can affect health-related quality of life and mental wellbeing, potentially increasing the likelihood of experiencing anxiety and low mood. Establishing this relationship in adults with pulmonary hypertension could
Early diagnosis of pulmonary hypertension has become critical now that effective treatment options exist. A study has shown that Corvista Health’s machine-learned algorithm can accurately diagnose pulmonary hypertension in a non-invasive way by assessing the elevation of mean pulmonary arterial pressure (mPAP). This system could potentially transform the approach to pulmonary hypertension diagnosis as a
A pivotal study is evaluating a non-evasive device, the Cardiac Performance System, (CPS), for pulmonary hypertension (PH) to reduce reliance on right heart catheterization. The study will compare the measurements obtained with the Cardiac Performance System with those obtained through right heart catheterization, the current gold-standard test used to measure pulmonary artery pressure. If validated,
Prostacyclin therapies, for pulmonary arterial hypertension, especially the parenteral ones, are associated with treatment burden, risks, and high costs. Authors Karen M Olsson, Jan Fuge, Da-Hee Park,Jan C. Kamp, and Marius M. Hoeper have investigated this possibility in a small series of pulmonary arterial hypertension patients treated with sotatercept. Withdrawal of selexipag was found safe,
A study published in Pulmonary Circulation on April 16, 2025 investigated whether Fitbit wearable devices can provide meaningful clinical information about activity and sleep patterns in pulmonary arterial hypertension (PAH) patients. A total of 110 participants completed the 12-week baseline monitoring period. The cohort was median age 52.7 years (IQR: 40.9–60.5), female predominant (84% female),
Pulmonary Artery Denervation (PADN) shows promise as a novel therapeutic approach targeting the sympathetic nervous system’s role in pulmonary hypertension, reveal the findings of a metanalysis reviewing 14 studies, involving 372 patients. Pulmonary Artery Denervation improved several key hemodynamic parameters and clinical outcomes. The meta-analysis was published in the May 2025 edition of the International Journal
The findings of a prospective study on 93 patients (66% women, 75% PAH, 25% CTEPH, 57±17 years), all on pulmonary hypertension-targeted oral medication, between 2013 and 2023, were recently published in the British Medical Journal Open Respiratory Research. These reveal that mean MPR (Medication Possession Ratio) and self-reported adherence were overall high, with 78% of patients
Pulmonary arterial hypertension (PAH), once seen mostly in young, healthy women, is now common among older adults with comorbidities in North America and Europe. In contrast, Latin American patients remain younger and healthier, with fewer related conditions. Possible Reasons Current Situation Latin American pulmonary arterial hypertension patients have: Future Concerns Rising obesity and aging populations
An article published in the New England Journal of Medicine on March 31 titled “Sotatercept in Patients with Pulmonary Arterial Hypertension at High Risk for Death” reports on the findings of ZENITH, a phase 3 trial which evaluated sotatercept as an add-on therapy for high-risk pulmonary arterial hypertension patients (functional class II-IV) already on maximum
A very important update on the phase 3 ZENITH trial for Winrevair (sotatercept) in pulmonary arterial hypertension was presented today at the American College of Cardiologists Annual Scientific Session in Boston, USA. The ZENITH trial evaluated Winrevair compared to placebo in adults with PAH, WHO Group 1, functional class III or IV, at high risk
Imatinib for pulmonary arterial hypertension was the first antiproliferative approach in this condition’s treatment and may still be relevant today despite its complicated history. Originally developed as a cancer therapy (tyrosine kinase inhibitor), it showed very good results in pulmonary arterial hypertension, creating a lot of expectation when the IMPRES study was presented at the
In a multicenter study from the FOCUS-PAH registry (2001-2022), researchers examined sex differences among 410 pulmonary arterial hypertension patients, and found that women represented 2 out of 3 patients (66.6 %) vs 33.4%). The findings, published in the International Journal of Cardiology on March 20, 2025 in an article titled “Sex differences in pulmonary arterial
The authors of a study titled “Engineered pulmonary artery tissues for measuring contractility, drug testing and disease modelling”, published in the British Journal of Pharmacology on Ferbruary 20, 2025, present an innovative technique to allow proxy evaluation of human pulmonary artery contractility. Vasoreactivity of the pulmonary arteries regulates blood flow through the lungs,they say, and
An article titled “Future treatment paradigms in pulmonary arterial hypertension: a personal view from physicians, health authorities, and patients”, was published in The Lancet on February 20, 2025. It reports on discussions held between a group of international experts at the 20th Global CardioVascular Clinical Trialists Forum, CVCT (Washington DC, USA), patients’ representatives, and members
