Shares of Axsome Therapeutics Inc. (NASDAQ:AXSM) hit a 52-week low on Aug. 9, falling 46.5% to close at $24.37, after the FDA said deficiencies in an NDA in major depressive disorder for its drug, AXS-05 (dextromethorphan + bupropion), would "preclude labeling discussions" for now.
With regard to agitation in Alzheimer’s disease (AD), doctors “are in a very difficult position right now,” said Axsome Therapeutics Inc. CEO Herriot Tabuteau. That’s because the products currently used off-label are antipsychotics – all of which carry an FDA black box warning “specifically against their use in elderly patients with dementia, including AD,” since they double the risk of stroke and of mortality.
Fueled by new positive data, Axsome Therapeutics Inc. plans to seek approval during the second half of 2020 for its dextromethorphan/bupropion modulated delivery tablet, AXS-05, an oral NMDA receptor antagonist to treat major depressive disorder.
Word from the FDA to Axsome Therapeutics Inc. about the effort with oral N-methyl-D-aspartate (NMDA) receptor antagonist AXS-05 in depression – and the company's accelerated push with the compound – had Wall Street watching the NMDA space with even more interest than usual.
