Pulmonary arterial hypertension (PAH) is a severe condition characterized by vasoconstriction and remodeling of the small pulmonary arteries, driven by a complement-dependent activation of macrophages, for which an effective treatment is lacking. Chinese researchers have investigated the potential of a complement C3 inhibitor polypeptide, CP40-KK, as an approach for treating PAH. To do this, they used a model in which PAH was induced in rats by monocrotaline.
Zymedi Co. Ltd. has signed a clinical cooperative research and development agreement (CRADA) with the National Heart, Lung and Blood Institute (NHLBI), part of the National Institutes of Health (NIH), to develop ZMA-001 for the treatment of pulmonary arterial hypertension (PAH).
Gossamer Bio Inc. shares (NASDAQ:GOSS) fell 74.6% to $2.36 Dec. 6 after the disclosure of phase II results that, while meeting the study's primary endpoint of reducing pulmonary vascular resistance vs. placebo, failed to show the company's pulmonary arterial hypertension (PAH) candidate, seralutinib, holding its own against the performance of Merck & Co. Inc.'s PAH candidate, sotatercept, in separate PAH studies.
The closely watched pivotal phase III trial called Stellar by Merck & Co. Inc. with sotatercept delivered in a big way for the company, helping to validate the firm’s $11.5 billion buyout about a year ago of Acceleron Pharma Inc.
Aqualung Therapeutics Corp. has been awarded two 3-year National Institutes of Health (NIH) Fast Track awards to support development of ALT-100 (enamptcumab), a humanized monoclonal antibody therapy for the chronic indications of pulmonary arterial hypertension (PAH) and inflammatory bowel disease (IBD).
Sonivie Ltd. has won breakthrough device designation from the U.S. FDA for the Therapeutic Intra-Vascular Ultrasound (TIVUS) system for renal artery denervation (RDN) to treat resistant hypertension. At the same time, the company revealed that it has bought the remaining intellectual property and other assets related to the use of the TIVUS System from Cardiosonic Inc.
A promising but side effect-ridden phase III study by Novartis AG with oral imatinib in pulmonary arterial hypertension (PAH) led Boston-based Aerovate Therapeutics Inc. to start exploring two years ago an aerosol form of the kinase inhibitor, and the project has won backing to the tune of $72.6 million in series A money.
