Sponsored by Inmune Bio, Inc. · Phase 2, Interventional, and Treatment
The goal of this Phase 2 MCI study is to determine whether 1.0 mg/kg XPro1595 is superior to placebo at improving measures of cognition, functioning and brain quality in individuals with MCI and biomarkers associated with neuroinflammation (APOE4) and to evaluate safety, tolerability, and efficacy of XPro1595.
This study is designed as a Phase 2, double-blind randomized, placebo-controlled study investigating the safety, tolerability, and efficacy of XPro1595 in patients with MCI. The planned dose is 1.0 mg/kg of XPro1595 and matching placebo.

Change in Mean Computer-based Cognitive Assessment (Cogstate) Composite score from Screening to Week 12
Change from Screening to Week 12 in Cogstate Composite mean score. Cogstate is a brief, computerized, neuropsychological battery to evaluate cognitive impairments in mild cognitive impairment (MCI), and Alzheimer's disease (AD). CogState assesses attention and memory functions - including Information processing speed, Visual attention, Working memory and Visual learning. Cogstate scores are measured on a linear scale (with no maximum score). A reduction in scores compared to baseline signifies an improvement in cognitive functions. The Cogstate battery will be administered at Screening and each week for 12 weeks. To assess the efficacy of XPro1595 compared with placebo on cognitive performance in patients with MCI

Change in imaging markers of brain quality
Change from Screening to Week 12 in regional brain glucose uptake as measured by F-fluorodeoxyglucose-Positron Emission Tomography (FDG-PET) scans Alzheimer's Disease (AD) is characterized by a chronic brain glucose deficit. White matter glucose deterioration is also evident in Mild Cognitive Impairment (MCI) and specific to limbic fascicles. We will quantify the change in regional brain glucose uptake for gray matter and white matter tracts using PET imaging and the F-fluorodeoxyglucose (FDG) radiotracer. PET maps will be registered to Magnetic Resonance (MR) anatomical images and corrected for partial volume effect. Standard uptake value ratios (SUVr) will be calculated using the cerebellum as a reference region. FDG-PET scans will be performed at Screening and Week 12.

Change in Alzheimer's Disease Cooperative Study - Mild Cognitive Impairment Activities of Daily Living (ADCS-MCI ADL)
Change from Screening to Week 12 in Alzheimer's Disease Cooperative Study - Mild Cognitive Impairment Activities of Daily Living (ADCS-MCI ADL) The 23-item ADCS-MCI-ADL Scale has good test-retest reliability, will be utilized to assess performance functioning in MCI patients (Galasko et al., 1997; Douglas Galasko et al., 2006; Pedrosa et al., 2010). The ADCS-ADL includes 18 items from traditional basic ADL scales and 5 items from instrumental activities of daily living scales (IADL) The possible range of total scores for the ADL Scale is 0-53 and higher scores indicate better functioning. The internal reliability was .91( Galasko et al., 1997; Douglas Galasko et al., 2006; Pedrosa et al., 2010). The ADCS-MCI ADL will be performed at Screening and Week 12. To assess the effect of XPro1595 compared with placebo on Activities of Daily Living (ADL) in patients with MCI

Change in Clinical Dementia Rating Scale Sum of Boxes (CDR-SB)
Change from Screening to Week 12 in Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) The CDR scale is a clinician-rated dementia staging system that tracks the progression of cognitive impairment in 6 categories (memory, orientation, judgement and problem solving, community affairs, home and hobbies, and personal care). Each category is scored on a 5-point scale in which None = 0, Questionable = 0.5, Mild = 1, Moderate = 2, and Severe = 3. The global CDR score is established by clinical scoring rules and has values of 0 (no dementia), 0.5, (questionable dementia), 1 (mild dementia), 2 (moderate dementia), and 3 (severe dementia). The Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) is obtained by adding the ratings in each of the 6 categories and ranges from 0 to 18 with higher scores indicative of greater impairment. To assess the effect of XPro1595 compared with placebo on cognition and global function in patients with MCI
Time frame: 12 Weeks
Number of participants who experience adverse events and serious adverse events
Clinically significant abnormalities of laboratory values, physical findings, electrocardiogram findings and other safety assessments will be recorded as adverse events if the findings meet the defined criteria for adverse events.
Time frame: Screening up to 28 days post last dose
Change in Goal Attainment Scale (GAS)
Change in Goal Attainment Scale (GAS) The achievement of each goal is rated on a 5-point attainment scale (-2, -1, 0, +1, +2) to allow standardized scoring of personalized outcomes. A participant's overall goal attainment is quantified using a formula that takes into account the number of goals that have been set, and the extent to which they are correlated with each other. For each identified goal area, the caregiver will be asked to give a detailed description of the patient's current (baseline) status and goal status, which will be recorded at the -1 and 0 levels on the 5-point scale, respectively. The remaining levels of the scale will then be set: somewhat better than the goal (+1), much better than the goal (+2), and much worse than the goal (-2). To evaluate the effect of XPro1595 compared with placebo on goal attainment scores
Time frame: 12 Weeks
Change in measures of activity
Change from Screening to Week 12 in activity metrics (time spent lying, sitting, standing, stepping, upright, in walking bouts, in-context specific walking bouts; number of steps, and sit-to-stand transitions) as measured by the activity monitor. Physical activity will be measured in real time using the activity monitor worn on the patient's wrist. Total activity counts per minute (higher activity counts = more activity) and number of steps taken will be derived from data. Patients will be equipped with the monitoring device during the screening period and activity metrics will be measured for 7 days prior to each EMACC assessment. Data will be measured at Screening, Week 1, Week 3, Week 6, Week 9 and Week 12. To assess the effect of XPro1595 compared to placebo on measures of activity
Time frame: 12 Weeks
Evaluate predictability of patient response after placebo administration and potential influence of study partners on outcome evaluation using the Multidimensional Psychological Questionnaire (MPsQ) with a 5 point scale
The Multidimensional Psychological Questionnaire (MPsQ) questionnaires have been designed to specifically measure patient personality characteristics associated with the placebo response. The MPsQ questionnaires are self-reported, and each item is rated on a 5-point scale ranging from 1 (strongly disagree) to 5 (strongly agree). MPsQs will be completed by the patient and separate MPsQs will be completed by the study partner at screening. MPsQs will be completed by the patient and separate MPsQs will be completed by the study partner prior to investigational product administration. The patient and study partner will complete MPsQs at Screening and Week 1. To measure patient personality characteristics associated with the placebo response.
