To strengthen its development efforts, Novo Nordisk A/S will collaborate in a deal that could bring Replicate Bioscience Inc. about $550 million. In return, Novo is getting an exclusive, worldwide license to use Replicate’s self-replicating RNA (srRNA) platform to develop the candidates. The two are aiming at targets in cardiometabolic diseases that include treatments for obesity and type 2 diabetes.

Leal Therapeutics Inc. is taking advantage of new genetic data that suggest products from metabolic pathways are involved in psychiatric and neurodegenerative diseases.

A few years after it was founded with the aim of taking RNA therapies to the next level, Arnatar Therapeutics Inc. emerged from stealth, disclosing a $52 million series A round raised in 2024 as well as U.S. FDA orphan and rare pediatric disease designations for ART-4, an antisense oligonucleotide candidate targeting the root cause of Alagille syndrome.

Eli Lilly and Co.’s regulatory ducks are lined up nicely with the latest positive top-line results from the phase III Attain-2 trial testing orforglipron, an oral glucagon-like peptide 1 (GLP-1) receptor agonist, in adults with obesity or overweight and type 2 diabetes.

Multiple datasets are due to roll out soon in the Prader-Willi syndrome (PWS) space, where contenders are trying varied mechanisms of action to tackle the rare genetic disorder characterized by insatiable hunger, or hyperphagia. In the mix are Aardvark Therapeutics Inc., Acadia Pharmaceuticals Inc., Rhythm Pharmaceuticals Inc. and Soleno Therapeutics Inc.

Rates of adverse events (AEs) gave pause to some on Wall Street, and shares of Viking Therapeutics Inc. (NASDAQ:VKTX) fell 42%, or $17.73, to close Aug. 19 at $24.36 after the firm reported 13-week data from the phase II trial with the oral tablet form of VK-2735, the company's dual agonist of the glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors.
