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
Yutrepia is a dry powder formulation of treprostinil, a prostacyclin analog. It is designed to enhance deep-lung delivery with an easy-to-use device requiring low inspiratory effort. Yutrepia was was tentatively approved by the Food and Drug Administration last year (see our article here), but the agency was waiting for regulatory exclusivity of a competing product
The EXPOSURE study compared survival rates between pulmonary arterial hypertension (PAH) patients newly treated with selexipag versus other pulmonary arterial hypertension-specific therapies. Survival analyses in EXPOSURE suggest a reduced risk of mortality among the cohort of patients newly initiated on selexipag compared with the modelled cohort newly initiated with other pulmonary arterial hypertension-specific therapies. Further
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,
Pulmonary arterial hypertension (PAH) represents a significant economic burden on society, as revealed by a comprehensive Swedish study published on Pulmonary Circulation on April 17, 2025, examining the societal costs associated with this condition. The research tracked patients across various pulmonary arterial hypertension subgroups—idiopathic/hereditary pulmonary arterial hypertension, pulmonary arterial hypertension associated with connective tissue disease,
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
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
Link: Liquidia Corporation announced on March 28, 2025, that the US Food and Drug Administration has accepted its resubmitted new drug application for YUTREPIA (treprostinil) inhalation powder. The treatment targets pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD). The FDA had previously granted tentative approval for both indications (see our
This review, published on Expert Opinion on Pharmacotherapy on March 19, 2025, chronicles the evolution of pulmonary arterial hypertension (PAH) treatment from historical milestones to current challenges. Beginning with Ernst von Romberg’s first clinical description in 1891 and the advent of cardiac catheterization, pulmonary arterial hypertension diagnosis and treatment have advanced significantly in past decades.
Corsair Pharma, Inc. is a private biopharmaceutical company. The company has just announced the successful completion of a preclinical program for Its treprostinil Prodrug Transdermal System and its plans to start a Phase 1 trial in Q2 of 2025. The Corsair transdermal patch is intended to provide steady and continuous blood levels of the prostacyclin
A recent study published in ESC Heart Failure (March 4, 2025) compared initial monotherapy versus combination therapy in pulmonary arterial hypertension (PAH) patients with cardiovascular comorbidities. Results showed that the combination therapy group experienced greater improvements in functional class, BNP/NT-proBNP levels, and overall risk status compared to monotherapy patients. However, no significant differences were observed
A recent analysis published in the International Journal of Cardiology Congenital Heart Disease (Volume 9, March 2025) examines the evolving landscape of pulmonary arterial hypertension (PAH). While traditionally viewed as primarily affecting young adult women without other health conditions, newer registry data from developed countries reveals a shift toward older patients with multiple co-morbidities like
The authors of the study “Revisiting treatment of pulmonary arterial hypertension in the current era: A Greek scientific document” published in the Hellenic Journal of Cardiology on February 19, 2025, presents a country-specific approach to care developed by a multidisciplinary team of cardiologists, pulmonologists, and intensivists. The authors discuss the advances in the field of
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
