Biotechnology Developments

Developer of the Betusphere platform technology for the creation of subunit recombinant vaccines based on a corpuscular natural adjuvant, betulin, for the prevention of pathogenic infections.

The platform helps increase the effectiveness and safety of vaccines, the speed of development and duration of the immune response, optimize the antigen dose, reduce the cost of production, and prevent competition of antigens in combined vaccines.

SARS-CoV-2 vaccine Betuvax, quadrivalent subunit influenza vaccine TetraFluBet, and combined pentavalent flu and coronavirus vaccine Combi 5V have been developed based on the Betusphere platform.

Betusphere Platform

Platform for developing corpuscular adjuvant-based recombinant protein vaccines. The use of an adjuvant for betulin-based vaccines makes it possible to increase immunogenicity (efficacy, protectiveness), the speed of development and duration of the immune response, optimize the antigen dose, and prevent competition of antigens in combination vaccines.

  • Betuvax-CoV-2
    Indication:
    COVID-19
    Indication:

    Primary/booster vaccination SARS-COV-2

    Stage:
    Clinical (primary), Preclinical (booster)
    Description:

    Russia’s first subunit recombinant vaccine based on spherical particles with the surface protein of coronavirus.

    The antigen used is part of the RBD domain of the S protein of coronavirus SARS-CoV-2. It is the RBD domain in response to which the immune system produces the largest number of virus-neutralizing antibodies.

    The Betuvax-CoV-2 vaccine does not contain inactivated or weakened particles of the new SARS-COV-2 coronavirus, does not contain vector viruses (adenovirus, influenza, measles, etc.), does not contain genetic material (RNA or DNA), inorganic adjuvants, so it is designed as a tool for multiple revaccinations, since it potentially does not have any short-term adverse reactions and does not cause excessive antigenic load.

    The Betuvax-CoV-2 vaccine is designed so that it can be quickly optimized for new strains of coronavirus.

  • TetraFluBet
    Indication:
    Influenza
    Indication:

    Influenza vaccination

    Stage:
    Clinical
    Description:

    Quadrivalent subunit influenza vaccine consisting of surface antigens of the influenza virus adsorbed on the adjuvant surface. The drug does not contain preservatives or stabilizing agents that could cause post-vaccination complications.

    The vaccine showed a high safety profile and low reactogenicity in preclinical and clinical trials due to its low antigen content (one vaccine dose contains 5 μg of hemagglutinin from each of the four seasonal vaccine strains).

  • Combi 5V (Nacimbio)
    Indication:
    Influenza + COVID-19
    Indication:

    Influenza + COVID-19 Combi vaccine

    Stage:
    Preclinical
    Description:

    Combined recombinant vaccine for protection against four seasonal strains of influenza viruses, as well as a component protecting against the SARS-CoV-2 virus.

    The vaccine was developed on the basis of the TetraFluBet and Betuvax-CoV-2 vaccines.

  • Betusphere
    Indication:
    Immunomodulator
    Indication:

    Immunomodulator

    Stage:
    Preclinical
    Description:

    The company began developing a substance with immunobiological activity. Preclinical studies are currently being completed.

  • RBT-402
    Indication:
    HPV
    Indication:

    HPV vaccination

    Stage:
    DSCVRY
    Description:
    A technology platform developed to create recombinant surface proteins of the five current HPV strains: 6, 11, 16, 18, 31.

  • RBT-501
    Indication:
    Allergies
    Indication:

    Allergies

    Stage:
    DSCVRY
    Description:
    The company began developing adjuvant recombinant vaccines based on natural allergens: Fel d1 (major feline allergen), Can f5 (major canine allergen), and Der p1 (major house dust mite allergen). The effectiveness of this technology has been proven by extensive clinical, blind, placebo-controlled studies abroad. The use of recombinant allergens will allow us to standardize therapeutic allergens, guaranteeing stable antigen circulation in the blood and the predictable effect of allergen-specific immunotherapy for allergic diseases.
