Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The investigational medicinal product (study medication) is F03 and the comparator is F03- matching placebo. F03 will be in the form of capsules in 5 mg strength.
Dose administered in each cohort will be as follows:
Cohort 1: F03 5mg or placebo once daily
Cohort 2: F03 5mg or placebo twice daily
Duration of administration: 8 weeks.
Mode of administration: oral capsule
Adherence of study drug administration will be checked at each visit (Baseline, Weeks 1, 2, 4, 6 and 8) through the study diary cards that the participants are required to complete and study medication returns.

Eligibility
Key inclusion criteria
- Be male or a postmenopausal female and be > or = 50 to < or = 75 years of age at screening
- Have a diagnosis of Mild Cognitive Impairment (MCI) due to Alzheimer’s Disease (AD) consistent with the criteria established by Petersen et al (1999) and the 2011 recommendations from the National Institute of Aging-Alzheimer’s Association workgroups within six (6) months of the screening visit based on:

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The study will be stratified by Centre only and a randomisation list will be prepared for each centre. A randomised block design will be used for each randomisation list. The randomisation number will be used for the medication kits and the numbering system for the case report form. An independent statistician will be assigned to prepare the final randomisation list.
This study is double - blind; therefore the Sponsor personnel, Investigator, site staff and patient will not know which treatment has been assigned.
If an emergency treatment code break is required then the Sponsors Medical Monitor and the site pharmacist will have access to the treatment assignment for each randomisation number.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
An independent statistician will be assigned to prepare the final randomisation list. The randomisation list will be produced by using a randomisation table created by computer software (namely SAS version 9.2).
