The toxic effects of high glucose concentrations contribute to the formation of ketoaldehyde free radicals, which, at an increased rate of their formation, leads to the development of oxidative stress in the nervous tissue. The planned study of the use of Cytoflavin® in diabetic polyneuropathy is substantiated by its antioxidant effect, which, by analogy with alpha-lipoic acid preparations, suggests its efficacy in the combined treatment of such patients. This clinical study is being conducted to assess the efficacy and safety of Cytoflavin® versus Placebo in diabetic polyneuropathy patients with type 2 diabetes. Study patients will receive study medication, 10 IV infusions followed by 75 days of oral intake. Clinical efficacy will be assessed by alleviation of symptoms (burning, numbness, pain and pricking), using the total symptoms score(TSS), after the completion of the treatment course.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '74 Years', 'minimumAge': '45 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Signed informed consent form;\n* Men and women aged 45 to 74 (inclusive);\n* Confirmed diagnosis of type 2 diabetes lasting for 1 year or more;\n* Permanent scheme of therapy (without changing doses and drugs) by oral hypoglycemic drugs and / or insulin, long-term or ultra-long (adjustment of insulin dose is possible within 10% from baseline dose) and / or agonists of glucagon-like peptide-1 receptors (GLP-1) for at least 12 weeks before screening;\n* HbA1c from 7.0 and not higher than 10.0%;\n* BMI 22-40 kg / m2;\n* Symptomatic distal sensorimotor diabetic polyneuropathy;\n* Baseline TSS (Total Syptom Score) ˃5 points;\n* Score ≥2 by at least one of the TSS symptoms;\n* The severity of pain by the corresponding TSS subscale ≤ 2;\n* NISLL (Neuropathy Impairment Score Low Limbs) ≥ 2 points;\n* Patient consent to use adequate contraceptive methods for the entire study;\n* Consent to maintain a stable diet, exercise, therapy and diabetes control throughout the study;\n* Ability to comply with all protocol requirements.\n\nExclusion Criteria:\n\n* Pregnant or lactating women, or women planning a pregnancy during a clinical trial;\n* Type 1 diabetes and other specific types of diabetes;\n* Acute metabolic complications of diabetes such as ketoacidosis or hyperosmolar state within 6 months prior to screening;\n* Therapy with short and ultra-short insulin within 3 months before screening;\n* Fasting plasma glucose at screening\\> 15 mmol / l;\n* The presence of severe complications of diabetes;\n* Epilepsy, epileptiform seizures, head trauma with loss of consciousness, tumor, inflammatory and demyelinating diseases of the central nervous system;\n* Diseases requiring prior or current treatment by systemic corticosteroid drugs, cytostatics or penicillamine;malignant neoplasms within the last 5 years (excluding basal cell carcinoma);\n* Cardiovascular diseases in the stage of decompensation at present or within 3 months before screening;\n* Uncontrolled arterial hypertension with systolic arterial pressure\\> 180 mm Hg and diastolic blood pressure\\> 110 mm Hg at screening;\n* Nephrotic syndrome, severe chronic renal failure or significant kidney disease with a level of glomerular filtration rate (GFR) \\<30 ml / min;\n* Active viral (hepatitis B and C) or cirrhotic liver disease;
