NCT03485495

Brief Summary

The purpose of this study is to obtain additional data on efficacy and safety of Divaza for adjustment of oxidative disorders in patients with cerebral atherosclerosis. It is assumed that the inclusion of the drug Divaza in the basic therapy will help reduce the severity of cognitive disorders, other clinical symptoms of cerebral atherosclerosis, reduce the impact of the disease on the quality of life of the patient. Participate in the study may be patients with a diagnosis of "cerebral atherosclerosis", which, against the backdrop of basic therapy with constant doses of drugs (within the last 4 weeks), to achieve a stable course of cerebral atherosclerosis, cognitive disorders without significant disability are detected.

  • underlying vascular disease (atherosclerosis and/or hypertension) and focal neurological symptoms combined with cerebral symptoms (headache, dizziness, tinnitus, impaired memory, working capacity);
  • ultrasound signs of atherosclerotic cerebrovascular lesions (according to MAH duplex scanning within 6 months preceding the patient enrollment into the study);
  • signs of morphological changes in the brain based on neuroimaging (CT/MRI 1.0-1.5 T) (subcortical and periventricular leukoaraiosis and/or focal changes in grey matter and white matter in the form of postischemic cysts and/or lacunar strokes and/or diffuse atrophic changes in the form of dilated cardiovascular system or subarachnoidal spaces).
  • Cognitive disorders (MoCa \<26).
  • Patients with unchanged dose and combination of basic therapy of cerebral atherosclerosis and hypertension during the previous month.
  • Patients who gave their consent to use reliable contraception during the study.
  • Availability of signed patient information sheet and informed consent form for participation in the clinical trial.

You may not qualify if:

  • History of subarachnoidal/parenchymatous/ventricular hemorrhage, cerebral tumour or another disease resulting in neurological disorders.
  • Ischemic-type stroke or any other acute cerebrovascular accident less than 6 months prior to the study with Modified Rankin Scale (mRs) \> 1 .
  • Cardiac sources of high risk or medium risk embolism (TOAST criteria).
  • Signs of acute or exacerbated chronic infectious diseases at or less than 2 weeks prior to screening.
  • History of CNS diseases including:
  • Inflammatory CNS diseases (G00-G09)
  • Systemic Atrophies Primarily Affecting the CNS (G10-G13)
  • Other degenerative diseases of the nervous system (G30-G32)
  • Demyelinating diseases of the CNS (G35-G37).
  • Dementia (F00-F03).
  • Previously diagnosed cardiovascular diseases with functional class III or IV (according to New York Heart Association, 1964).
  • Hypothyroidism, diabetes mellitus and other somatic diseases at decompensation stage.
  • Uncontrollable hypertension: SBP \> 180 mm Hg and/or DBP \> 110 mm Hg.
  • Diseases of lower limb veins (lower limb varicose veins, deep venous thrombosis, etc.) at decompensation stage.
  • Any other severe concomitant pathology which, according to the investigator, may interfere with the patient's participation in the study.
