Abstract
Aim. To study the efficacy and safety of a drug product based on the succinic acid complex with trimethylhydrazine used to treat patients with asthenic syndrome after a new coronavirus infection (COVID-19).
Materials and methods. A prospective, multicenter, comparative, randomized, double-blind, placebo-controlled study of the safety and efficacy of sequential therapy with Brainmax® enrolled 160 patients 12–16 weeks after coronavirus infection (no more than 12 months). The study was conducted at 6 healthcare centers in different regions of the Russian Federation. At the enrollment, clinical and neurological examination and the following tests were performed: complete blood count, urinalysis, blood chemistry, coagulation test, pulse oximetry, electrocardiography, glomerular filtration rate calculation (according to Cockcroft–Gault formula) were performed. Also, the patients were assessed using the following tools: VAS headache rating scale, MFI-20 asthenia scale, PSQI index, FAS-10 fatigue assessment scale, Dizziness Handicap Inventory (DHI), MoCA-test for cognitive impairment assessment, Beck Anxiety Inventory, Kérdö Autonomic Index.
Results. The primary endpoint was the mean reduction in the MFI-20 asthenia scale score after the therapy (Visit 5, 41st day of therapy) compared to data from Visit 0 (beginning of therapy). A clinically significant advantage of the study drug versus the placebo was demonstrated, with a median absolute change in the MFI-20 score of -19.5 [-27; -11] points in the Brainmax® drug group and -3 [-7; 1] score in the placebo group (p<0.001). A significant sleep quality improvement according to the PSQI index was shown in the study group: by -2.5 [-4; -1] points versus no improvement in the placebo group (0 [-3; 0], p<0,001). Significant differences were also noted for the following secondary endpoints: PSQI sleep quality scale, FAS-10 fatigue assessment scale, DHI, and Beck Anxiety and Depression Inventory. There was also a decrease in patients' complaints of cognitive deterioration according to the CGI scale.
Conclusion. Our study clearly demonstrated the efficacy and high safety profile of Brainmax® in a representative sample of patients with the post-COVID syndrome.
