Optimized Trial Design for Xanamem in Alzheimers

Sep 26, 2023

Actinogen Medical (ASX: ACW) has optimized the design of the XanaMIA Phase 2b Alzheimer's disease trial to expedite results and reduce costs. The FDA-approved three-arm trial aimed at confirming Xanamem®'s safety and clinical benefits remains unchanged, except for the elimination of the 5 mg dose group, postponing dose-ranging to a potential Phase 3 trial. The trial still demonstrates Xanamem's clinical benefit in Alzheimer's patients.

Changes include a 10 mg or placebo daily regimen, a reduced cohort of 220 patients with elevated blood pTau biomarkers (previously 330 patients), Australian sites enrolling the initial 100 patients, and an interim analysis at 24 weeks for initial efficacy and safety results. These modifications are expected to save approximately $30 million by June 2025. Further expansion depends on data from the XanaCIDD trial in mid-2024 and the redesigned XanaMIA interim analysis in H1 2025. Patient recruitment for XanaMIA Phase 2b is set to begin by year-end, building on Xanamem's established safety profile from over 300 participants.
