Actinogen is advancing a revolutionary oral therapeutic, Xanamem®, through pivotal trials to transform treatment for Alzheimer’s disease and major depressive disorder. Our vision is to improve lives by targeting brain cortisol with precision and innovation.
Our Fundamentals
In conjunction with the US FDA and other regulatory authorities, we strive for excellence in science and clinical data within our programs. As a result, we’ve conducted multiple high-quality clinical trials to bring our molecule, Xanamem, to this Phase 2 stage of development.
We are valued and respected by patients, physicians, and industry peers to bring Xanamem’s development forward. Science, data and transparency guide us to bring hope and potentially change the world of cognitive impairment forever.
Building on the solid scientific rationale for Xanamem’s action, we are rapidly developing programs in multiple disease areas, with a priority on Alzheimer’s disease and depression.
Xanamem is a cutting-edge therapy and world-class product that reduces cortisol (the “stress hormone”) levels in the brain. As a result, it is a catalyst for new approaches in managing neurodegenerative and other illnesses.
About Us
Actinogen Medical (ACW) is an ASX-listed, biotechnology company developing a novel therapy for neurological diseases associated with dysregulated brain cortisol. There is a strong association between cortisol and detrimental changes in the brain, affecting cognitive function, harm to brain cells and long term cognitive health.
Cognitive function means how a person understands, remembers and thinks clearly. Important cognitive functions include episodic and working memory, attention, problem solving, and language.
We are currently developing our lead compound, Xanamem®, as a revolutionary new therapy for Alzheimer’s Disease, Major Depressive Disorder, Fragile X Syndrome, and other neurological diseases where reducing cortisol inside brain cells could have a positive impact. The cognitive dysfunction, behavioral abnormalities, and neuropsychological burden associated with these conditions is significantly debilitating for patients, and there is a substantial unmet medical need for new and improved treatments.
About Xanamem® (emestedastat)
Xanamem’s novel mechanism of action works by blocking the production of intracellular cortisol through the inhibition of the 11β-HSD1 enzyme in the brain. Xanamem is designed to get into the brain after it is absorbed in the intestines upon swallowing its capsule.
Chronically increased cortisol is associated with cognitive decline in Alzheimer’s Disease, potentially linked to cognitive impairment in Depression and cognitive impairment and anxiety in Fragile X Syndrome, and other diseases.
The Company has studied 11β-HSD1 inhibition by Xanamem in more than 300 volunteers and patients, so far finding a statistically significant improvement in cognition over placebo in healthy, older volunteers. A series of Phase 2 studies in multiple diseases is being conducted to further confirm and characterize Xanamem’s therapeutic potential.
