Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Change in ADAS-Cog11 scale score from treatment restart to 12 months post-restart (0–9 points: normal; 10–15 points: mild cognitive impairment [MCI]; 16–24 points: mild stage, GDS 3 or GDS 4; 25–30 points: moderate stage, GDS 4; 31–45 points: moderate-to-severe stage, GDS 4 or GDS 5; >45 points: severe stage, GDS 6 or higher). Measurement time: At baseline and Week 52.

Key secondary outcomes:

1.- Proportion of patients with stability/improvement in ADAS-Cog11 at 24 months (0–9 points: normal; 10–15 points: mild cognitive impairment [MCI]; 16–24 points: mild stage, GDS 3 or GDS 4; 25–30 points: moderate stage, GDS 4; 31–45 points: moderate-to-severe stage, GDS 4 or GDS 5; >45 points: severe stage, GDS 6 or higher). Measurement time: Week 104. 2.- Degree of dementia (Measured by GDS, where 1 = no cognitive deficit, 2 = very mild cognitive deficit, 3 = mild cognitive deficit, 4 = moderate cognitive deficit, 5 = moderately severe cognitive deficit, 6 = severe cognitive deficit, 7 = very severe cognitive deficit). Measurement time: At baseline, weeks 52, and 104. 3.- General cognitive status (Measured by MoCA, where ≥26 points: normal; 25–22 points: MCI; 21–18 points: mild impairment; 17–14 points: moderate impairment; <14 points: severe impairment). Measurement time At baseline, weeks 52, and 104. 4.- Functional status index for basic activities of daily living (Measured by the Katz Index, where: A. Independent in all functions; B. Independent in all functions except one; C. Independent in all functions except bathing and one other; D. Independent in all functions except bathing, dressing, and one other; E. Independent in all functions except bathing, dressing, toileting, and one other; F. Independent in all functions except bathing, dressing, toileting, mobility, and one other; G. Dependent in all functions; H. Dependent in at least two functions but not classifiable as C, D, E, or F). Measurement time: At baseline, weeks 52, and 104. 5.- Functional status index for instrumental activities of daily living (Measured by the Lawton Index, where: Women: 0-1 point = total dependence, 2-3 points = severe, 4-5 points = moderate, 6-7 points = mild, 8 points = independent; Men: 0 points = total dependence, 1 point = severe, 2-3 points = moderate, 4 points = mild, 5 points = independent). Measurement time: At baseline, weeks 52, and 104. 6.- Psycho-behavioral manifestations (Measured by the NPI, where the maximum score is 120 points; a higher score indicates a worse condition for the patient). Measurement time: At baseline, weeks 52, and 104. 7.- Mini-Mental State Examination (MMSE) (30–27 points: no cognitive impairment; 26–24: possible or questionable cognitive impairment; 23–17: mild cognitive impairment; 16–10: moderate cognitive impairment; <10: severe cognitive impairment). Measurement time: At baseline, weeks 52, and 104. 8.- Adverse Events (AEs) (AE severity: serious, non-serious; AE type: classified according to categories established in CECMED Regulation 45/2007; AE intensity: mild, moderate, severe; AE causality: definite, very probable, probable, possible, unlikely, unrelated, not evaluable; Action taken regarding the drug: no change, dose modification, temporary or permanent discontinuation; Outcome: recovered, recovered with sequelae requiring treatment, recovered with sequelae not requiring treatment, death; AE duration: time elapsed between AE detection and resolution; Organ and system: according to CTCAE v5.0 terminology, identifying them based on anatomical or physiological system, etiology, or purpose). Measurement time: Up to week 104. 9.- Laboratory parameters (Hemoglobin; Hematocrit, according to values stipulated at each center). Measurement time: At baseline, weeks 26, 52, 78, and 104.
