Kalvista Pharmaceuticals Inc.’s positive phase III news Feb. 13 with sebetralstat, an oral on-demand kallikrein inhibitor, in hereditary angioedema (HAE), sparked Wall Street speculation about competitor Pharvaris BV with deucrictibant, a bradykinin B2 receptor antagonist.
Alnylam Pharmaceuticals Inc.’s decision to change its analysis plan for the phase III Helios-B trial of RNAi therapeutic Amvuttra (vutrisiran) to treat transthyretin amyloidosis with cardiomyopathy, pushing top-line results back by three months, pressured its share price (NASDAQ:ALNY) down by 10% on Feb. 15, while also boosting shares of competitor Bridgebio Pharma Inc. (NASDAQ:BBIO) by 14%.
Inventiva SA has halted enrollment in its pivotal phase III Nativ3 trial with nonalcoholic steatohepatitis (NASH) candidate lanifibranor after a patient experienced raised liver enzymes indicative of autoimmune hepatitis. The resulting delays to the study could spell trouble for the firm, which estimates its cash runway will only see it through to the start of the third quarter 2024.
Based on positive phase III study data, Applied Therapeutics Inc. plans to take its CNS-penetrant aldose reductase inhibitor to the U.S. FDA to talk about an NDA for treating the rare disease sorbitol dehydrogenase (SORD) deficiency. Interim data from 12 months of treatment showed govorestat (AT-007) hit the study’s primary endpoints along with several key secondary endpoints. The double-blind, placebo-controlled registrational study of patients ages 16 to 55 is ongoing, with another 12 months of data yet to come. SORD, a hereditary axonal neuropathy created by sorbitol dehydrogenase gene mutations, affects about 3,300 people in the U.S. and about 4,000 in Europe, according to Applied Therapeutics.
South Korean biopharmaceutical firm GNT Pharma Co. Ltd. on Feb. 13 reported positive findings from a domestic phase III trial of its neuroprotectant therapy, nelonemdaz (NEU-2000), for patients with acute ischemic stroke.
Otsuka Pharmaceutical Co. Ltd.’s AVP-786 missed the primary endpoint for a third time in a phase III trial for agitation associated with dementia due to Alzheimer’s disease (AD). Two previous phase III trials also failed to show statistical significance for AVP-786.
Kalvista Pharmaceuticals Inc. is promising to “change the paradigm” in the treatment of hereditary angioedema, after announcing positive phase III data for its oral on-demand kallikrein inhibitor sebetralstat. Rather than waiting four to five hours to self-administer therapy, as is the case for approved injectable on-demand therapies, there was a median time to dosing of 10 minutes after the start of an attack in the ongoing open label extension trial and a median time to dosing of 41 minutes in the 136-patient placebo-controlled phase 3 trial.
CSL Ltd. will review the data further to see if there is a path forward for CSL-112 (human apolipoprotein A-I) after the phase III AEGIS-II trial failed to meet the primary efficacy endpoint in reducing the risk of major adverse cardiovascular events in patients following an acute heart attack.
AN2 Therapeutics Inc.’s decision to pause enrollment in the phase III portion of its phase II/III testing epetraborole in treatment-refractory Mycobacterium avium complex lung disease, citing potentially lower-than-expected efficacy from a blinded aggregate analysis of the phase II portion, left analysts and investors with little to do but speculate on the program’s viability going forward.
Synlogic Inc. jolted Wall Street with news that the firm is scrapping for futility Synpheny-3, its pivotal study with labafenogene marselecobac (SYNB-1934) for phenylketonuria, and will evaluate strategic options. Shares of the Cambridge, Mass.-based firm (NASDAQ:SYBX) fell 48.7%, or $1.68, to end Feb. 9 at $1.77.
