The XanaMIA Phase 2b Alzheimer's Trial

What is the purpose of the XanaMIA phase 2b trial in mild to moderate Alzheimer’s disease?

The purpose of the trial is to test a potential new treatment for improving cognitive performance, including issues with memory, concentration, decision-making and the like.

This trial investigates the effectiveness of an oral medication called Xanamem® in improving cognitive symptoms in patients with MCI or mild or moderate dementia due to AD.

Xanamem was created to block the excess production of cortisol – the stress hormone – inside brain cells. High levels of cortisol are often seen in people with Alzheimer’s disease.

The trial medication is experimental.

®Xanamem is a registered trademark of Actinogen Medical Limited

What does the trial involve?

Participation in the trial will be required for approximately 11.5 months (50 weeks). This includes a pre-screening period (if required) of 6 weeks, a screening period of up to 4 weeks, a treatment period of 9 months (36 weeks) and a follow-up period of 4 weeks.

Randomized’ means that you will be assigned by chance (like flipping a coin) to receive either the research project treatment or a placebo (no active ingredients).

Double-blind’ means neither doctor, participant, nor Actinogen will know which treatment was assigned at randomization.
