Interventions: Dietary Supplement: Cogmax®

Registration Number: NCT03835325

Lead Sponsor: Eurofarma Laboratorios S.A.

Brief Summary: Complaints about memory loss are very common in women in the menopausal transition period. The effectiveness of estrogen replacement therapy in cognitive improvement is controversial. Partial positive results were obtained in some studies with regard to memory improvement, so far no standard treatment considered effective in these cases. Effective pharmacological approaches to the treatment of memory loss associated with menopause are an unmet medical need. Cogmax® is a multivitamin and mineral supplement that contains numerous key elements for cognitive function, and may be a safe therapeutic option in these cases.

The multicenter, non-comparative (single-arm) phase IV clinical trial will be conducted with 80 female participants aged 45 to 60 years and menopausal memory loss complaint.

After 3 months of using multivitamin and mineral supplement, memory and attention will be reevaluated through specific questionnaire and the Stroop Test Victoria version.

Detailed Description: This multicenter, non-comparative phase IV clinical trial will be conducted at brazilian clinical trial centers under the auspices of Eurofarma Laboratories S.A. Recruitment for the study will begin after the relevant ethical and regulatory approvals and will have an estimated duration of 4 months.

The study will include 80 female participants aged between 45 and 60 years and menopausal memory complaints who consent to participate in the study by signing the informed consent form.

To be included, participants must meet all inclusion criteria and none of the exclusion criteria. Each participant will initially complete a selection period with a maximum duration of 14 days for evaluation of eligibility. Participants will then be treated with Cogmax® in the dosage of two capsules per day for 12 weeks.

Primary Outcome Measures

Name	Time	Method
Change From Baseline of the Score Number Relative to the Self-efficacy Factor, Consisting of Average Scores on the Domains Capacity, Control and Change of the Meta-memory in Adulthood Questionnaire - Portuguese Reduced Version	12 weeks after the start of the treatment (Baseline)	The primary outcome measure will evaluate the change from baseline in the score relative to the self-efficacy factor (SEF), consisting of arithmetic average on the domains capacity, control and change of the Meta-memory in Adulthood Questionnaire - Portuguese reduced version (MIAr) SEF final - SEF baseline ≤ 0 (no improvement in the measured memory capacity between the initial and final evaluations) SEF final - SEF baseline \> 0 (improvement in the memory capacity measured between the initial and final evaluations) The arithmetic average on the domains capacity, control and change range from 1 (worse) to 5 (better).

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in Stroop Test Victoria Version	12 weeks after the start of the treatment	Change from Baseline in Stroop Test Victoria version
Change From Baseline in the Score of the Meta-memory in Adulthood Questionnaire - Portuguese Reduced Version	12 weeks after the start of the treatment (Baseline)	The short version of Meta-memory in Adulthood Questionnaire is composed of 39 multiple-choice statements that are answered in a five-point likert scale, evaluating seven factors of meta-memory (strategy, task, capacity, change, anxiety, achievement and locus). Secondary Outcome Measures will evaluate the change from baseline of seven factors of meta-memory. The variation of the total sum obtained by means of the MIA questionnaire will be compared between all the visits in which the questionnaire was applied, ie, visit of selection (VS), visit 2 (V2) and final visit (VF).
The Overall Assessment of the Effectiveness of the Treatment by the Participant	12 weeks after the start of the treatment	The overall assessment of the effectiveness of the treatment by the participant, through multiple-choice statements in a five-point likert scale 1. My memory worsened in relation to the beginning of this treatment. 2. There has been no improvement in my memory, which remains the same as when I started this treatment. 3. My memory improved a little compared to how it was before the beginning treatment. 4. My memory improved a lot compared to how it was before the beginning of this treatment. 5. My memory returned to normal, that is, it returned to being as before the menopause.
