One of the target areas for the development of the Russian pharmaceutical industry at present is the development of next-in-class drugs medicines. These are original, patent-protected drugs that act on known biological targets, improved or modified in structure and mechanism of action compared to existing, successfully proven medicine. The article presents the results of an expert council on the management of patients with multiple sclerosis and the place of new original medicines of the JSC BIOCAD company (SamPEG-IFN-β1a and divozilimab) in multiple sclerosis therapy algorithm.

Objective: Cognitive dysfunction is common in multiple sclerosis (MS). The Brief International Cognitive Assessment for MS (BICAMS) battery of tests has been suggested as a measure for the evaluation of the cognitive status of MS patients. This study aims to validate the BICAMS battery in the Russian population of MS patients.

Alemtuzumab (Lemtrada) is a recombinant humanized IgG1 kappa monoclonal antibody to the surface cell glycoprotein, a CD52 differentiation cluster. The drug is approved for use in more than 65 countries, including the Russian Federation. The drug is one of the most effective methods of treating patients with aggressive multiple sclerosis, but the risk management plan should be followed.

Multiple sclerosis is a central nervous system disease with autoimmune and neurodegenerative mechanisms of development. This disease can lead to severe disability and neurological defects. Although its etiology and pathogenesis remain unclear, research data show that multiple sclerosis is a multifactorial disease, the development of which depends on environmental factors, as well as a genetic predisposition.

The clinical course of multiple sclerosis (MS) is characterized by great variability. 'Aggressive' MS, a concept used in the last 10 years, is associated with atypical course of the disease, which is manifested by more frequent exacerbations, the rapid increase in disability and pronounced signs of radiological activity according to MRI. The review presents data on the effectiveness of three monoclonal antibody drugs - natalizumab, alemtuzumab and ocrelizumab.

Background: NTZ is approved in Russia for the treatment of highly active relapsing remitting multiple sclerosis and is reimbursed via federal budget program. However, no data about NTZ treatment in Russia and the effect of federal reimbursement have been performed so far.

Objective: To characterize the population of patients receiving natalizumab and assess the efficacy and risk-management plan (RMP) implementation of NTZ therapy in routine clinical practice in Russia.

New terminology used by neurologists with multiple sclerosis (MS). The current use of terms 'definite' MS, 'MS signs', 'retrobulbar neuritis' and 'optic neuritis', 'relapse and exacerbation, types of MS course, criteria of effectiveness of MS therapy, NEDA, NEP, NEPAD; the classification therapy methods - 'escalation', 'induction' and therapy of immune reconstitution (TIR), therapy of maintenance/escalation (TME) and discussed.

Modern multiple sclerosis therapy with disease-modifying drugs is characterized by the risks of dangerous infectious complications. In the last 5 years, there have been several reports of severe, sometimes lethal, listeriosis infection in patients treated with alemtuzumab. This article presents a clinical case of lethal listeriosis meningoencephalitis, which developed within 7 days after the completion of the first cycle of alemtuzumab therapy.

The emergence of modern methods of immunohistochemistry and further development of MRI has led to a deeper understanding of gray matter (GM) pathology in multiple sclerosis (MS). GM involvement can be extensive including both demyelination (cortical lesions) and neuroaxonal damage. The mechanisms of GM damage in MS remain insufficiently studied.

Long-term disease modifying therapy (DMD) therapy is the basis of modern MS treatment, effiecacy of which is modulated by the patient's adherence to therapy. One of the possible solutions of low adherence improvement is the use of innovative drugs and the development of more convenient regimens of injectable medications. This article gives a brief review of peg-interferon β-1a clinical trials.

Multiple sclerosis is a chronic demyelinating and neurodegenerative disease of the central nervous system, in which autoimmune inflammation and oxidative stress play essential pathogenetic roles. Activation and infiltration of immune cells in brain tissues, lipid peroxidation products, mitochondrial dysfunction, defective antioxidant protection, and many other pathological factors result in demyelination, axonal injury and death, and apoptosis of oligodendrocytes and neurons, all of which causes constant progression of the disease. The new oral agent for the treatment of relapsing-remitting multiple sclerosis (RRMS), dimethyl fumarate (DMF), helps change the pathogenetic mechanisms of the disease, thus decreasing the rate of exacerbations, slowing down disease progression, and reducing the risk of radiological progression of the disease.

The importance of MRI stuides in the control over treatment efficacy in multiple sclerosis and appropriate recommendations on drug substitution during treatment are discussed. We suggest low, middle or high risk in respect to the efficacy of current treatment. Accordingly, drug substitution can be related with the low level of fears for all three criteria or the moderate level for any two criteria or the high level for any one criterion.

Objective: To study the efficacy and tolerability of generics (interferon beta-1a biosimilans) cinnovex for intramascular introduction and genfaxon-44 for subcutaneous injections in multiple sclerosis (MS).

Material And Methods: One hundred patients were treated with cinnovex and 104 patients were treated with genfaxon-44 during one year. Patient's status was assessed using clinical approach, psychometric scales and MRI.

Unlabelled: The aim of the study was to assess the capabilities of diffusion kurtosis imaging (DKI) in diagnosis of the glioma proliferative activity and to evaluate a relationship between the glioma proliferative activity index and diffusion parameters of the contralateral normal appearing white matter (CNAWM).

Material And Methods: The study included 47 patients with newly diagnosed brain gliomas (23 low grade, 13 grade III, and 11 grade IV gliomas). We determined a relationship between absolute and normalized parameters of the diffusion tensor (mean (MD), axial (AD), and radial (RD) diffusivities; fractional (FA) and relative (RA) anisotropies) and diffusion kurtosis (mean (MK), axial (AK), and radial (RK) kurtosis; kurtosis anisotropy (KA)) and the proliferative activity index in the most malignant glioma parts (p<0.

We summarized the 1-year experience of using the Russian Β-interferon-1b biosimilar (infibeta) in 123 patients including 65 patients with relapsing-remitting multiple sclerosis (RMS) and 58 patients with secondary progressive multiple sclerosis (SPMS). The significant decrease in the frequency of exacerbations per year was seen during the first year of treatment. We also noted the stabilization of the process of disability without the rise in EDSS scores in more than 50% of patients.
