NCT04966429

Brief Summary

Hypotheses: 1. Subjects with mild post-stroke cognitive impairment (PSCI) are at risk of developing vascular dementia (VaD). Maraviroc treatment in patients suffering from mild PSCI will halt its progression and improve cognitive outcome by affecting synaptic plasticity. 2. CCR5 inhibition produces an anti-inflammatory and anti-atherogenic effect by lowering macrophage infiltration and adhesion molecules. Thus, PSCI patients treated with Maraviroc will present a better inflammatory profile and a deceleration of carotid atherosclerosis, vs. placebo. Objectives: To investigate the safety and efficacy of Maraviroc 150 mg and 600 mg per day vs. placebo in patients with recent subcortical stroke who experience mild PSCI on progression/improvement of clinical symptoms of post-stroke cognitive impairment, change in disease biomarkers and inflammatory profile. The study will include 150 participants aged 50-86 years treated with Maraviroc 150mg or 600mg per day compared to placebo for 12 months in 3 sites.

Eligibility Criteria

Age50 Years - 86 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Men and women aged 50 to 86 years;
  • Able to fully comprehend and sign an informed consent form;
  • Fulfill diagnostic criteria for Mild Cognitive Impairment (MCI), as outlined by Albert and colleagues, and indicated by: 1. concern about a change in cognition, in comparison with the person's previous level, expressed by the participant, an informant who knows the patient well, or an investigator; 2. Montreal Cognitive Assessment (MoCA) score lower than or equal to 26; 3. general preservation of independence in functional abilities; 4. no dementia.
  • Fulfill the diagnostic criteria for PSCI/subcortical vascular cognitive impairment that developed after the documented stroke/TIA, as outlined by Skrobot and colleagues. This requires the presence of a cognitive syndrome (as defined in Section A below) and SVD (as defined in Section B below). Impairment in at least one cognitive domain and mild to no impairment in instrumental activities of daily living (IADLs)/activities of daily living (ADLs), respectively (independent of the motor/ sensory sequelae of the vascular event); A. Cognitive Syndrome defined as: 1. Dysexecutive Syndrome: Some impairment in goal formulation, initiation, planning, organizing, sequencing, executing, set-shifting and maintenance, or abstracting; 2. Memory Deficit: Some impairment in recall, relative intact recognition, less severe forgetting, benefit from cues. B. Small Vessel Ischaemic Disease defined as: Evidence of relevant cerebrovascular disease by brain imaging (in the last 1-24 months) defined as the presence of both: (i) Periventricular and deep WMLs (grading scale \>1 on the Fazekas score) plus at least one lacunar infarct; and (ii) Absence of cortical and/or cortico-sub-cortical non-lacunar territorial infarcts and watershed infarcts, indicating large vessel disease, signs of normal pressure hydrocephalus, or other specific causes of WML.
  • Presence or a history of neurological signs as evidence for cerebrovascular disease at least 1 month prior to enrollment.
  • Community-dwelling;
  • Able to comply with scheduled visits, treatment plan, and other trial procedures;
  • Able to walk independently;
  • Modified Rankin score \<2.
  • Willing to have a study partner (see Appendix 1 for definition of study partner) throughout the study.

You may not qualify if:

  • Patients diagnosed with dementia or significant cognitive impairment as defined by a MoCA score \<17 at screening and clinical evaluation excluding diagnosis of dementia, or other neurological conditions (multiple sclerosis, Parkinson's disease, epilepsy, etc.) that affects cognition and mobility;
  • Hemorrhages and cerebral edema (e.g., subarachnoid hemorrhage, intracerebral hemorrhage, subdural hematoma, epidural hematoma).
  • Patients in a state of coma or with severe disturbance of consciousness, aphasia, agnosia, or deafness that subsequently affects expression and communication.
  • Significant acute medical illness including: drug overdose, severely disturbed liver, kidney or lung function, anemia, hypothyroidism, or uncontrolled diabetes
  • Presence of cortical involvement on neurologic examination including aphasia, extinsion etc.;
  • Diagnosed previously with a genetic cause of VCI (e.g., CADASIL);
  • Taking medications that may negatively affect cognitive function;
  • Unable to meet the specific scanning requirements of the 3T MRI;
  • History of hepatitis or elevated hepatic transaminases or bilirubin; positive serology for Hepatitis B or C; positive serology for HIV;
  • Serum creatinine over 1.8;
  • Subject has a current or past diagnosis of bipolar or related disorders, intellectual disability, or cluster b personality disorder (e.g., borderline personality disorder, antisocial personality disorder, histrionic personality disorder, and narcissistic personality disorder), psychotic disorder, schizophrenia, obsessive-compulsive disorder, and substance/alcohol use disorders other than nicotine in the past year (including barbiturates, methadone, opiates, cocaine, cannabinoids, and amphetamine/ methamphetamine).
  • Subject has suicidal ideation with intent to act during screening phase or on Day 1, or has a history of suicidal behavior within the past year.
  • Diagnosis of attention deficit disorder;
  • Prolongation of the corrected QT (CTc) interval;
  • Use of drugs with possible interactions with Maraviroc.
  • +5 more criteria
