EVANTHEA: Precision Medicine Approach for Early Dementia & Mild Cognitive Impairment
Study Details
Study Description
Brief Summary
The goal of this clinical trial is to compare a precision medicine approach to the standard-of-care for people with mild cognitive impairment or early-stage dementia. Precision medicine approach starts with the completion of many tests and then the study doctor uses the test results to carefully prepare a treatment plan that is best for the individual person to help treat many of the underlying causes of mild cognitive impairment or early-stage dementia.
The main question the study aims to answer is:
• Does the precision medicine approach improve memory (cognitive function) better than the current standard-of-care treatment in people with mild cognitive impairment or early-stage dementia during a 9-month treatment period? This is a randomized clinical trial which means that a group of people that meet the study requirements will be assigned at random or by chance (like toss of a coin) to receive either the precision medicine treatment or the current gold standard (standard-of-care). People assigned to the precision medicine group will receive precision medicine for 9-months while those assigned to the standard-of-care group will follow that approach for 9-months, followed by an opportunity to receive up to six months of precision medicine, if desired.
Participants will be asked to:
-
Have their blood drawn for extensive lab testing and collect urine and stool samples as well
-
Carefully follow instructions received from their study doctor and study team
-
Make lifestyle changes as prescribed by the study doctor and study team based on your precision medicine program
-
Take supplements and medications prescribed by the study doctor.
-
Once officially in the study (after meeting study entry or screening requirements), participate in ten (10) monthly visits with the study doctor, and other members of the study team as scheduled.
-
Complete cognitive tests at scheduled visits during the study
-
Have a study partner with you during visits and to help support you on the program Researchers will compare test results between the two study groups to see if the precision medicine approach improves those tests results over the time of the study, resulting in the improvement of cognition over a 9-month treatment period.

Detailed Description
The precision medicine treatment approach to be evaluated in this clinical trial is a novel, functional, lifestyle intervention for the treatment of mild cognitive impairment or early-stage dementia. The protocol focuses on optimization of a diverse set of metabolic parameters coupled with lifestyle medicine and clinical nutrition strategies that address the mismatch in these contributors. The approach is personalized for each participant and based on more than 150 data points, including lab evaluations, brain scans, genomic evaluation, cognitive testing, and a detailed medical and family history. Importantly, this progressive treatment approach is based on continued optimization through iterative treatment and metabolic characterization.
The precision medicine treatment approach includes a core set of interventions (Precision Medicine-Core) and a set of interventions that are based on the clinical subtype of dementia (Precision Medicine-Cognitive Subtypes). All participants randomized to the precision medicine treatment approach group will receive the core treatment program. The elements of the core treatment program include diet, physical exercise, mental exercise, sleep optimization, and stress reduction.
In addition, all participants randomized to the precision medicine treatment approach will be evaluated for all putative or potential underlying drivers of dementia including: 1) inflammatory factors (Type 1 Inflammatory), 2) glycotoxic factors (Type 1.5 Glycotoxic), 3) atrophic factors (Type 2 Atrophic), toxic factors (Type 3 Toxic), vascular factors (Type 4 Vascular), and traumatic factors (Type 5 Head Trauma).
This study will use a pragmatic, randomized, multicenter, control group design in which participants will be randomized to a 9-month precision medicine treatment approach or a 9-month standard-of-care treatment approach. Participants in the standard-of-care group will receive the standard-of-care mild cognitive impairment and early-stage dementia. Following completion of the 9-month intervention period, participants in the standard-of-care group will be eligible to receive the precision medicine treatment approach.
During the course of the 9-month precision medicine treatment approach, participants and study partners will be scheduled for regular visits with members of the study team at each practice. These visits will be scheduled at approximately 4-week intervals following randomization. Cognitive function tests will be performed at baseline (Visit 1), Month 3 (Visit 4), Month 6 (Visit 7), and Month 9 (Visit 10). Cognitive testing includes the MoCA to be performed by a blinded psychometrician prior to randomization and then 1-2 weeks before the 3-, 6-, and 9-month visits. The CNS Vital Signs will be performed by each staff at each of the six participating sites. Participants in the standard-of-care treatment group will complete a similar set of visits at the same intervals during this time.
A final follow-up visit will occur within 4 weeks of completion of Visit 10 to complete all effectiveness and safety follow-up assessments. Following completion of the final follow-up visit, all participants in the standard-of-care treatment group will be eligible for initiation of a 6-month precision medicine treatment approach. Safety data will be collected for participants in both groups through completion of the 6-month precision medicine intervention period for participants initially randomized to the standard-of-care treatment group. Periodic unblinded safety reviews are planned at approximately 1-month intervals for the full duration of the trial. These reviews will be conducted by the Study Oversight and Safety Review Committee.
Participants will be enrolled from six geographically-diverse clinical practices and randomized to either the precision medicine treatment approach (Group A) or the standard-of-care control group (Group B). The population to be enrolled will be heterogenous in terms of demographic and clinical characteristics of their cognitive dysfunctions. In addition, the precision medicine intervention will be heterogenous because, by definition, precision medicine is personalized to target the specific metabolic abnormalities that are identified in each participant as uniquely associated with mild cognitive impairment or early-stage dementia. Given the real-world settings, heterogeneity in study participants, and heterogeneity of the specific precision medicine components, a pragmatic, randomized, controlled trial will provide the best evaluation of the precision medicine treatment approach while offering maximum external validity and the ability to generalize findings from this study to precision medicine practice settings and patients who are treated in the US.
Study Design
Arms and Interventions

Outcome Measures
Primary Outcome Measures
- Changes in mean Montreal Cognition Assessment (MoCA) scores over 9 months [Baseline and Months 3, 6, and 9 (end of study treatment)]
Compare changes over time between Group A and Group B in mean MoCA scores over 9 month treatment period
- Changes in mean CNS Vital Signs Neurocognitive Index Scores over 9 months [Baseline and Months 3, 6, and 9 (end of study treatment)]
Compare changes over time in mean score on the CNS Vital Signs Neurocognitive Index over 9 month treatment period. Standard scores are used. 100 is the mean score with standard deviation of 15. No min/max value for the Index. Standard scores are normal distribution but there is a limit to human performance, towards 200. Higher score over time is better outcome.
Secondary Outcome Measures
- Changes over time in mean score on the Alzheimer's Questionnaire-21 (AQ-21) / Alzheimer's Questionnaire-20 (AQ-20) [Baseline and Months 3, 6, and 9 (end of study treatment)]
Compare changes over time between Group A and Group B in mean Alzheimer's Questionnaire scores. AQ-21 is baseline; AQ-20 is a modified version of the AQ-21 to address changes from baseline. The AQ© total score is based on the sum of points for items with a yes response. The range of possible scores is 0 to 27. Score interpretation: A score of four points or less is regarded as normal. A score between five and 14 points inclusive suggests mild cognitive impairment. A score of 15 or more points suggests dementia. Lower score over time is a better outcome.
- Changes over time in mean score on the Patient-reported Outcome Measurement Information System (PROMIS-10). [Baseline and Month 9 (end of study treatment)]
Evaluate Group A treatment compared with Group B treatment with regard to changes over time in mean PROMIS-10 score. The PROMIS Global-10 is a 10-item patient-reported questionnaire in which the response options are presented as 5-point (as well as a single 11-point) rating scales. The results of the questions are used to calculate two summary scores: a Global Physical Health Score and a Global Mental Health score. The possible score ranges from 0 to 20 points in each case. 0 points represent the patient's most severe physical and/or mental impairment, while 20 points represent the best possible state of health.
- Discontinuation rates [Throughout 9-month study treatment period]
Evaluate acceptability of the precision medicine intervention approach by comparing discontinuation rates in Group A and Group B participants
- Safety: Type, frequency, severity, relatedness, and expectedness of adverse events and serious adverse events. [Throughout 9-month study treatment period]
Determine the safety of the Group A treatment compared with Group B treatment based on the type, frequency, severity, relatedness, and expectedness of adverse events and serious adverse events.
Other Outcome Measures
- Changes over time in findings on volumetric magnetic resonance imaging (MRI). [Baseline and Month 9 (end of study treatment)]
Compare the impact of a Group A treatment approach with Group B treatment in regards to changes over time in findings on volumetric magnetic resonance imaging (MRI).
- Change in serum biomarker, methylation epigenetics. [Baseline and Month 9 (end of study treatment)]
Compare changes in methylation epigenetic results between Group A and Group B participants at the same timepoints, beginning and end of treatment.
- Changes in serum biomarker, P-tau. [Baseline and Month 9 (end of study treatment)]
Compare changes P-tau results between Group A and Group B participants at the same timepoints, beginning and end of treatment. Lowering of P-Tau over course of the study is positive outcome.
