At the Breakthroughs in Muscular Dystrophy special meeting held in Chicago Nov. 19-20, 2024, and organized by the American Society of Gene & Cell Therapy (ASGCT), multiple interventions at the RNA level were among the approaches that were presented to fight muscular dystrophies.

Edwards Lifesciences Corp. revealed excellent one-year data highlighting the performance of its newest generation Sapien 3 Ultra Resilia valve. Patients treated with the transcatheter aortic valve replacement system experienced lower rates of mortality and reintervention compared to its predecessors.

Pulmonary arterial hypertension (PAH) is a condition characterized by high blood pressure in the pulmonary arteries, potentially leading to heart failure. Previous research had found that knockout of Egln1 specific to endothelial cells, which encodes prolyl 4-hydroxylase-2, led to spontaneous PAH development.

Since the isolation of the gene that causes Duchenne muscular dystrophy (DMD), scientists have progressed in understanding the mechanisms that lead to muscular diseases that can be evident from the early stages of childhood. This has led to the development of diagnostics and therapeutics, some approved by the FDA.

With the U.S. FDA approval of Attruby (acoramidis) for transthyretin amyloidosis with cardiomyopathy (ATTR-CM), Bridgebio Pharma Inc. is taking on an industry giant. The next-generation, oral, small-molecule stabilizer of transthyretin will take on Pfizer Inc.’s Vyndamax (tafamidis, Vyndaqel), a TTR stabilizer approved in 2019 for ATTR-CM but expected to lose exclusivity in late 2028. The approval was based on a phase III study that showed Attruby significantly reduced death and cardiovascular-related hospitalizations. The NDA, which had a Nov. 29 PDUFA date, was approved Nov. 22.

Ultromics Ltd. received clearance from the U.S. FDA for Echogo Amyloidosis, its artificial intelligence-enhanced software that helps with the early diagnosis of cardiac amyloidosis, enabling timely intervention that can significantly improve patients' quality of life and extend survival.

Medtronic plc and Tempus AI Inc. launched the ALERT study to better understand and address the racial, ethnic, gender and geographic disparities associated with guideline-recommended treatments for aortic stenosis and mitral valve regurgitation. Currently, white patients represent 91% of people who receive TAVR procedures, a minimally invasive procedure that sharply reduces complications and improves quality of life in patients with narrowed heart valves.

The U.S. FDA granted Brightheart SAS 510(k) clearance for its artificial intelligence software which helps doctors detect congenital heart defects in fetuses. The software will transform prenatal ultrasound evaluations of the fetal heart and improve the outcomes for newborns, Cécile Dupont, Brightheart’s CEO, told BioWorld.

At the American Heart Association’s Scientific Sessions, E-Therapeutics plc presented preclinical data for ETX-258, a Galomic siRNA being developed for the treatment of heart failure.
