NCT07062198

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)

  • Change in body height from baseline through-out the study

    Visit 1, Visit 5 (13 weeks), Visit 8 (26 weeks)

  • +18 more secondary outcomes

Study Arms (2)

Treatment Arm

EXPERIMENTAL
Drug: Combined metabolic activators

Placebo Arm

PLACEBO COMPARATOR
Other: Collagen and maltodextrin

Interventions

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 Subjects who cannot tolerate (e.g., diarrhoea) taking full dose will be withdrawn from the study.

Treatment Arm

As placebo, a total of 20g of compound primarily containing collagen and maltodextrin will be administered. Placebo contains strawberry aroma flavouring and colouring agent.
