The first economic modelling of Boston Scientific Corp.’s pulsed field ablation system in U.K.’s National Health Service showed that it is more cost-effective as a treatment for paroxysmal atrial fibrillation compared to standard cryoablation.

Viking Therapeutics Inc. is diving more deeply into developing obesity treatments and investors like an accelerated timetable the company has proposed. On June 25, Viking shares (NASDAQ:VKTX) catapulted 28.3% upward to close at $64.68 each.

A phase II failure with SAGE-324 in essential tremor (ET) had Wall Street speculating about the fate of Sage Therapeutics Inc.’s partnership with Biogen Inc. Shares of Cambridge, Mass.-based Sage (NASDAQ:SAGE) ended July 24 at $10.38, down $2.70, or 20.6%, after the firm disclosed top-line results from the phase II Kinetic 2 dose-ranging study of oral SAGE-324 (also known as BIIB-124) for ET. The trial did not show a statistically significant dose-response relationship based on the primary endpoint, the Essential Tremor Rating Assessment Scale (TETRAS) Performance Subscale Item 4 (upper limb) total score.

Aussie biotech Alterity Therapeutics Ltd. released interim data of an open-label phase II trial for lead candidate ATH-434 for treating multiple system atrophy that showed 43% of participants improved, with 29% showing either stable or improved neurological symptoms.

Many respiratory syncytial virus (RSV) disease vaccines are for older adults but Merck & Co. Inc.’s monoclonal antibody, MK-1654 (clesrovimab), which just produced positive top-line phase IIb/III data, aims at a far smaller and younger market. Data for protecting healthy preterm and full-term infants from RSV disease show the double-blind, randomized, placebo-controlled clinical trial hit all its primary efficacy and safety endpoints, including the incidence of RSV-associated medically attended lower respiratory infection for 150 days compared to placebo.

Innovent Biologics Inc.’s glucagon-like peptide-1 receptor (GLP-1R) and glucagon receptor (GCGR) dual agonist, mazdutide, met the primary endpoint and all key secondary endpoints in a phase III type 2 diabetes trial in Chinese adults. “Mazdutide is the first and fastest-developed GLP-1R/GCGR dual agonist in the world, and we are actively promoting the development of mazdutide for weight loss, T2D and other indications,” Lei Qian, Innovent’s vice president of clinical development, said.

The U.S. FDA approval won in June by Argenx SE of subcutaneously given Vyvgart Hytrulo (efgartigimod alfa and hyaluronidase) for adults with chronic inflammatory demyelinating polyneuropathy (CIDP) sparked interest in other prospects taking aim at the rare disease. Some – including Argenx – are going after generalized myasthenia gravis and multifocal motor neuropathy with their compounds.
