Amylyx Pharmaceuticals Inc.’s acquisition of GLP-1 receptor antagonist avexitide for $35.1 million from Eiger Biopharmaceuticals Inc. could bring the firm “to the forefront of the obesity and diabetes drug landscape in a unique way,” said H.C. Wainwright analyst Andrew Fein. Co-CEO and co-founder Justin Klee said the deal came after Amylyx checked out “hundreds of assets” over the last few years, and its closing brought added attention to phase III-ready, first-in-class avexitide.
Acorda Therapeutics Inc. has filed for bankruptcy and agreed to sell its assets, including rights to its three commercialized drugs, to German biopharma Merz Therapeutics GmbH for $185 million. Palo Alto, Calif.-based Eiger Biopharmaceuticals Inc. also filed for bankruptcy.
One hepatitis delta virus player (HDV) has dropped out after Eiger Biopharmaceuticals Inc.’s phase III effort with peginterferon lambda turned up safety issues, while others remain busy in a space highlighted during last November’s meeting of the American Association for the Study of Liver Diseases. Shares of Palo Alto, Calif.-based Eiger (NASDAQ:EIGR) closed Sept. 13 at 41 cents, down 28 cents, or 40.6%, on word that the company is stopping the Limt-2 study in patients with chronic HDV.
Strong data for pegylated interferon lambda, Eiger Biopharmaceuticals Inc.’s experimental COVID-19 treatment, boosted the company stock (NASDAQ:EIGR) 23% on Feb. 9 as the company continues to seek regulatory approval. That approval path is blocked as interferon lambda is not currently approved by the U.S. FDA for any use. In October, the company said it would not submit emergency authorization use request after feedback from the FDA.
Top-line primary data from week 48 of Eiger Biopharmaceuticals Inc.'s phase III D-LIVR study of lonafarnib, a prenylation inhibitor for treating chronic hepatitis delta virus, also known as hepatitis D, hit statistical significance vs. a placebo in the composite primary endpoint.
Despite global drops in COVID-19 infections and because variants never rest, Eiger Biopharmaceuticals Inc. is taking its strong top-line phase III data of pegylated interferon lambda to global regulatory agencies for approval. The type III interferon that stimulates immune responses significantly reduced the risk of COVID-19-related hospitalizations or emergency room visits longer than six hours by 50% and death by 60%. The results prompted Eiger to say it would submit the data to the FDA for an emergency use authorization – and also to the EMA and Asian agencies – as soon as it could.
Gilead Sciences Inc.’s move to grab Myr GmbH for about €1.15 billion (US$1.39 billion) in cash up front, with €300 million if the latter’s Hepcludex (bulevirtide) wins FDA clearance, put chronic hepatitis delta virus (HDV) in the headlines and benefited the stock of another player in the space: Eiger Biopharmaceuticals Inc. (NASDAQ:EIGR), which closed at $10.27, up $1.51, or 17%.
Although Eiger Biopharmaceuticals Inc. sees more would-be opportunities with ultra-rare disease-targeting Zokinvy (lonafarnib), the company’s vice president of clinical and development operations, Colin Hislop, said that “at the moment, we’re very clearly focused on the population identified in the label, because it fits most closely with the mechanism of action.”
