Amylyx Pharmaceuticals Inc. has nominated AMX-0318, a long-acting glucagon-like peptide-1 (GLP-1) receptor antagonist, as a development candidate for post-bariatric hypoglycemia and other rare diseases.
The U.S. FDA has issued yet another complete response letter (CRL) for dasiglucagon, a glucagon receptor agonist, being developed by Zealand Pharma A/S for treating congenital hyperinsulinism, an ultra-rare disease that is also being targeted by at least two other companies. This CRL is pegged to the timing of a third-party manufacturing facility reinspection that was done in August and September. The agency also wants some additional clinical analysis from the phase III study.
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.
With the recent removal of its amyotrophic lateral sclerosis drug from the market, Amylyx Pharmaceuticals Inc. is looking to revive investor interest with interim data from its phase II Helios study testing the same drug, AMX-0035 (sodium phenylbutyrate plus taurursodiol), in Wolfram syndrome, a rare indication in which Amylyx could be leading the charge.
Less than a month after disclosing that its confirmatory phase III trial of Relyvrio (sodium phenylbutyrate plus taurursodiol) fell short of its endpoint, Amylyx Pharmaceuticals Inc. is withdrawing the amyotrophic lateral sclerosis (ALS) drug from the market.
Tweaks made to the design of the phase III trial called Phoenix (vs. the narrowly positive phase II Centaur study) with Amylyx Pharmaceuticals Inc.’s amyotrophic lateral sclerosis (ALS) drug Relyvrio (sodium phenylbutyrate plus taurursodiol) didn’t work. Now, the Cambridge, Mass.-based firm is facing possible withdrawal of the treatment from the U.S. and Canada, where it’s known as Albrioza. Shares of Amylyx (NASDAQ: AMLX) closed March 8 at $3.36, down $15.61, or 82.3%, after the firm disclosed top-line results from Phoenix, a global, 48-week, randomized, placebo-controlled phase III effort with Relyvrio, also known as AMX-0035.
Axonal degeneration is a key early pathogenic driver of amyotrophic lateral sclerosis and other neurodegenerative diseases. Activation of calpain-2 (CAPN2) is thought to be the critical effector behind axonal degeneration. Amylyx Pharmaceuticals Inc. has presented data on their CAPN2 inhibitor antisense oligonucleotide (ASO) AMX-0114 as a potential therapeutic for axonal degeneration.
The EMA is standing firm on its refusal to recommend approval of the amyotrophic lateral sclerosis (ALS) treatment Albrioza in Europe after re-examining Amylyx Pharmaceuticals Inc.’s marketing authorization application and remaining unconvinced that the main study demonstrated the drug effectively slows disease progression.
