All 20 US trial sites are now open in the XanaMIA phase 2b/3 trial that is studying oral Xanamem® vs. placebo for 36 weeks, followed by an open label extension of active Xanamem for up to 24 months

SYDNEY, July 22, 2025 /PRNewswire/ -- Actinogen Medical Limited (ASX: ACW) is encouraging individuals and their loved ones affected by Alzheimer's disease to take part in a groundbreaking clinical trial that could transform the way we treat this devastating condition.

The trial is enrolling people diagnosed with mild to moderate Alzheimer's disease, offering them a chance to participate in cutting-edge research aimed at stabilizing the cognitive and functional decline of Alzheimer's.

Xanamem inhibits the production of the "stress hormone", cortisol, in key areas of the brain that are linked to memory and critical thinking. Watch a two-minute explainer video on how Xanamem works here.

The trial involves taking a single pill once a day of Xanamem or matching placebo ("sugar pill") and a series of clinic visits for the assessment of Alzheimer's progress. It does not involve frequent brain scans or complicated procedures such as lumbar puncture.

All participants at the end of the XanaMIA trial are eligible for Actinogen's open-label extension trial of active Xanamem for up to 24 months. This extension trial will open to completed XanaMIA participants in early 2026.

About Xanamem (emestedastat)

Xanamem's novel mechanism of action is to control the level of cortisol in the important areas of the brain through the inhibition of the cortisol synthesis enzyme, 11β-HSD1, without blocking normal production of cortisol by the adrenal glands. Xanamem is a first-in-class, once-a-day pill designed to deliver high levels of brain cortisol control in regions where 11β-HSD1 is highly expressed such as the hippocampus. Chronically elevated cortisol is associated with progression in Alzheimer's Disease and excess cortisol is known to be toxic to brain cells. Elevated cortisol is also associated with depressive symptoms. Xanamem has demonstrated excellent brain target engagement and in human trials has shown potential to slow progression of Alzheimer's disease and improve depressive symptoms in patients with moderately severe depression.
