A New Therapeutic Approach
How It Works
The components of AXS-05, DM and bupropion, each target different CNS receptor systems. Combining the distinct and independent mechanisms of action of these two compounds may be useful in the treatment of CNS disorders. However DM is rapidly metabolized in humans. As a result, it is difficult to attain potential therapeutic blood levels of DM when it is dosed as a single agent. In addition to its activity at CNS receptors, the bupropion component of AXS 05 serves as a novel drug delivery method to inhibit DM metabolism and thereby increase its blood concentrations.
AXS-05 is currently in a Phase 3 trial for the treatment of treatment resistant depression (TRD), a Phase 2/3 trial for the treatment of agitation associated with Alzheimer’s Disease (AD) and a Phase 2 trial for the cessation of smoking.
An Independent Data Monitoring Committee (IDMC) conducted an interim analysis of the Phase 3 STRIDE-1 trial of AXS-05 in TRD in April 2018 and recommended that the study continue to full enrollment as well as indicating that AXS-05 appeared safe and well-tolerated.
Treatment Resistant Depression (TRD)
Patients diagnosed with major depressive disorder (MDD) are defined as having TRD if they have failed two or more antidepressant therapies. There are approximately 3 million estimated patients with TRD in the United States.

Agitation in Patient’s with Alzheimer’s Disease (AD)
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that manifests initially as forgetfulness advancing to severe cognitive impairment and memory loss. It is a common form of dementia and afflicts an estimated 5 million individuals in the United States, a number that is anticipated to increase to approximately 14 million by 2050. In addition to cognitive decline, individuals diagnosed with AD typically experience behavioral and psychological symptoms including agitation which is reported in approximately 45% of patients. Agitation is characterized by emotional distress, aggressive behaviors, disruptive irritability, and disinhibition.
More about AD
The modulation of DM allows it to reach therapeutic plasma levels allowing DM to act on targeted CNS receptor systems. Combining the distinct and independent mechanisms of action of these two compounds with AXS-05 may be useful in the treatment of a variety of CNS disorders.
