A longitudinal dataset indicating the utility of plasma pTau for patient selection in clinical trials of patients with mild Alzheimer's Disease (AD) and the likely therapeutic benefit of oral Xanamem in this population
SYDNEY, March 30, 2023 /PRNewswire/ -- Actinogen Medical ASX: ACW ("ACW" or "the Company") is pleased to announce that its Chief Medical Officer, Dr Dana Hilt will make an oral presentation to the International Conference on Alzheimer's and Parkinson's Diseases and related neurological disorders (ADPD™ 2023) later today in Gothenburg, Sweden.
Dr Hilt was invited to present Actinogen's novel Phase 2a data as an oral presentation in a symposium session entitled AD Drug Development Clinical Trials. The presentation details the unique longitudinal dataset demonstrating 1) the utility of using the plasma biomarker pTau181 for selection of patients with a more progressive form of mild AD in clinical trials and 2) an encouraging beneficial effect of Xanamem on clinical endpoints of function (CDR-SB[1]) and cognition (NTB[1]) in these patients.
In his presentation Dr Hilt analyses four studies that have shown positive results for ACW's small molecule drug Xanamem® that pave the way for the 330-person XanaMIA Phase 2b AD trial to commence in the coming months. Key points include:
1. CDR-SB (Clinical Dementia Rating Scale – Sum of Boxes); NTB (Neurologic Test Battery of cognition) |
The upcoming XanaMIA Phase 2b trial will study 330 individuals treated with 5 mg, 10 mg or placebo over 24 weeks. Patients will have early stage, progressive AD defined as mild cognitive impairment (MCI) or mild AD and elevated plasma pTau181. Key endpoints will be a cognitive composite based on the NTB described in Dr Hilt's presentation and the CDR-SB.
Dr Hilt's presentation will be available at https://actinogen.com.au/corporate-presentations/
Dr Steven Gourlay, Actinogen's CEO and MD, said:
"Actinogen is excited to present its novel Phase 2a dataset that is one of the first to show that the blood pTau biomarker is a highly effective method for selection of patients with a progressive form of mild Alzheimer's disease. As a simulation of the upcoming Phase 2b XanaMIA trial the data give us confidence in our study design, endpoints and patient selection criteria."

About Actinogen Medical
Actinogen Medical (ACW) is an ASX-listed, biotechnology company developing a novel therapy for neurological and neuropsychiatric 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. Cognitive functions include memory, attention, reasoning, awareness and decision-making.
About Xanamem
Xanamem's novel mechanism of action is to block the production of cortisol inside cells 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 elevated cortisol is associated with cognitive decline in Alzheimer's Disease, and Xanamem has shown the ability to enhance cognition in healthy, older volunteers. Cognitive impairment is also a feature in Depression and many other diseases. Cortisol itself is also associated with depressive symptoms and when targeted via other mechanisms has shown some promise in prior clinical trials.
The Company has studied 11β-HSD1 inhibition by Xanamem in more than 300 volunteers and patients, so far finding a statistically significant improvement in working memory and attention, compared with placebo, in healthy, older volunteers in two consecutive trials and clinically significant improvements in patients with biomarker-positive mild AD. Previously, high levels of target engagement in the brain with doses as low as 5 mg daily have been demonstrated in a human PET imaging study. A series of Phase 2 studies in multiple diseases is being conducted to further confirm and characterize Xanamem's therapeutic potential.
Xanamem is an investigational product and is not approved for use outside of a clinical trial by the FDA or by any global regulatory authority. Xanamem® is a trademark of Actinogen Medical.
