Brief Summary
This randomised, double-blinded, placebo-controlled study aims to establish metabolic improvements in subjects diagnosed with Alzheimer's Disease (AD) by treatment with CMA2 including N-acetyl-L-cysteine (NAC), L-carnitine-L-tartrate (LCAT), nicotinamide (niacinamide), and L-serine. Participants will take the drug CMA2 or a placebo twice a day for 26 weeks. They will visit the clinic 4 times for checkups and tests.

Outcome Measures
Primary Outcomes (1)
Change in Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-Cog) score from baseline to end-of-treatment
The test administrator adds up points for the errors in each task for a total score ranging from 0 to 70. The greater the dysfunction, the greater the score. A score of 70 represents the most severe impairment and 0 represents the least impairment
Visit 1, Visit 5 (13 weeks), Visit 8 (26 weeks)
Secondary Outcomes (23)
Change in Mini Mental State Examination (MMSE) score from baseline to end-of-treatment
Visit 1, Visit 5 (13 weeks), Visit 8 (26 weeks)
Change in Alzheimer's Disease Cooperative Study - Activities of Daily Living (ADCS-ADL) score from baseline to end-of-treatment
Visit 1, Visit 5 (13 weeks), Visit 8 (26 weeks)
To evaluate compliance daily two doses treatment in patients
Visit 5 (13 weeks), Visit 8 (26 weeks)
Change in body weight from baseline through-out the study
Visit 1, Visit 5 (13 weeks), Visit 8 (26 weeks)

Treatment Arm
EXPERIMENTALPlacebo Arm
PLACEBO COMPARATORInterventions
A total of 20g of CMA2 with strawberry aroma and colouring agent will be given. The IMP will be provided as a soluble powder packed as individual dosages in identical sachets. The powder should be dissolved in 200 ml preferably cold water before use. The powder can also be used on yoghurt or other food. The subjects will take two daily oral doses of the IMP, one dose just after breakfast and one dose just after dinner. Subjects who cannot tolerate (e.g., diarrhoea) taking full dose will be withdrawn from the study.
As placebo, a total of 20g of compound primarily containing collagen and maltodextrin will be administered. Placebo contains strawberry aroma flavouring and colouring agent.

- Drug and/or alcohol abuse.
- Subjects considered as inappropriate for this study for any reason (noncompliance etc.) per investigator assessment.
- Administration of another new chemical entity (defined as a compound that has not been approved for marketing) or has participated in any other clinical study that included drug treatment with the last administration within 3 months prior to administration of IMP in this study.
