Publication number: 20210403534Abstract: A therapeutic composition is described that can be used for treating or prevention of diseases association with modulation of activity of human IL-1?. In certain aspects, the disclosed composition is based on engineering of a heterodimeric protein assembly that is capable of binding to human IL-1? and attenuating its function. The heterodimeric protein assembly comprises extracellular portions of human IL1-R1 and of human IL-1RAcP, or their functional fragments. Each, the IL1-R1 portion and the IL-1RAcP portion, is fused to a distinct mutant of Fc portion of the human Ig Gamma-1. The two distinct Fc mutants in the heterodimeric protein assembly are engineered as to favor the heteromeric dimer formation between the two Fc mutants over any homomeric assembly. The therapeutic composition has been formulated for administration into humans and animals.Type: ApplicationFiled: September 14, 2021Publication date: December 30, 2021Inventors: Yan Lavrovsky, Alexey Repik, Mikhail Samsonov, Sergei BARBASHOV, Vasily IGNATIEV

Publication number: 20210115143Abstract: Fully human anti-PD-L1 antibodies and their corresponding applications. Fully human antibodies capable of specifically binding to human PD-L1 were obtained by employing a yeast display library-based screening technique and also by affinity maturation to further improve their affinity for PD-L1. The fully human anti-PD-L1 antibodies show good specificity, affinity and stability. They are capable of enhancing T cell activity by binding to activated T cells, while significantly inhibiting tumor growth, and can be used in the diagnosis and treatment of PD-L1-related cancers and other associated diseases.Type: ApplicationFiled: April 18, 2018Publication date: April 22, 2021Applicant: R-PHARM OVERSEAS, INC.Inventors: Yan LAVROVSKY, Ting XU, Sergei BARBASHOV, Alexey REPIK, Mikhail SAMSONOV, Vasily IGNATIEV, Shorena ARCHUADZE

Publication number: 20170073391Abstract: A pharmaceutical composition is described that can be used for treating or prevention of diseases association with bone resorption, particularly of a metastatic carcinoma. In certain aspects, the composition is based on a polypeptide which includes the leading 215 amino acids of the human osteoprotegerin followed by the Fc portion of the human IgG1 protein. Pharmaceutical formulations are provided that are suitable for administering the pharmaceutical composition into primates via subcutaneous and intravenous routes.Type: ApplicationFiled: March 6, 2014Publication date: March 16, 2017Inventors: Yan Lavrovsky, Ting Xu, Irina Kostareva, Shorena Archuadze, Vasily Ignatiev, Mikhail Samsonov, Alexey Repik

Patent number: 7288293Abstract: A process for plasma treatment of an object's surface to be treated comprising the creation of a plasma, the application of the plasma to the surface to be treated, and the excitation of the surface to be treated, such that it vibrates and undulates. The energy for excitation of the surface may come from the process creating the plasma, from an external source, or from a combination of these two sources. The vibration preferably takes place while the plasma is being applied to the surface to be treated, but depending on the treatment to carry out, it may also take place just prior to and/or just after the application phase.Type: GrantFiled: March 26, 2003Date of Patent: October 30, 2007Assignee: APIT Corp. S.A.Inventors: Pavel Koulik, Mikhail Samsonov, Alexander Cherepanov, Evguenii Petrov

Patent number: 6278241Abstract: A four-nozzle plasma generator comprising two anode electrode chambers and two cathode electrode chambers connected to DC power sources and generating four plasma jets of which the shape and the path are determined by an external magnetic field system. The plasma jets converge on a central area into which the material to be processed is injected, in order to form a single plasma stream. The nozzles are symmetrically arranged on a hood which includes a flat water-cooled diaphragm provided with a central aperture.Type: GrantFiled: November 23, 1998Date of Patent: August 21, 2001Assignee: TePla AGInventors: Vladimir Enguelcht, Pavel Koulik, Evgenia Zorina, Stanislav Begounov, Rudolph Konavko, Anatolii Saitschenko, Mikhail Samsonov, Ioulia Tsvetkova

Patent number: 6050215Abstract: A plasma stream generator with a closed-configuration arc for achieving a stream comprising a central area at a uniform or very low temperature. The generator comprises a higher or even much higher number of electrode pairs than is usual, whereby rows may be formed and, in particular, an elongate stream, i.e. a curtain, may be achieved. The orientation problems resulting from the closeness of the jets and the increased attraction/repulsion therebetween are solved by means of magnetic devices (coils) of which there are generally three for a pair of electrode chambers.Type: GrantFiled: September 8, 1998Date of Patent: April 18, 2000Assignee: IST Instant Surface Technology S.A.Inventors: Pavel Koulik, Rudolph Konavko, Anatolii Saishenko, Mikhail Samsonov
