Evaluation of Safety of Contraloid Acetate in Patients With Mild Cognitive Impairment Due to Alzheimer's Disease

• Status: Recruiting
• Trial end date: 2021-11-01
• Target enrollment: 0
• Participant gender: All

Summary

Patients with mild cognitive impairment due to Alzheimer's disease (MCI due to AD) are at high risk to develop Alzheimer´s dementia. The therapeutic agent Contraloid has the potential to influence the chronic neurodegenerative process of AD. As Contraloid was so far only administered to healthy subjects, the rational of the proposed study is first to collect safety data in patients diagnosed with MCI due to AD, as the absorption, distribution, metabolism and excretion processes may be altered by disease, aging, comorbidities and concomitant drug therapies. Additionally, the design of a subsequent phase II study will be based on the data of this study. The results of the exploratory analyses will enable power calculations and the identification of the most useful and reliable biomarkers for the subsequent proof of concept phase II study.
