In vivo testing of human monoclonal antibodies in a hamster model

Project leader: Prof. Dr. Albert Osterhaus

Antibodies represent a unique and highly adaptive option for the development of customised therapeutics. The natural healing of viral infections or effective protection against reinfection is crucially supported by highly effective virus-neutralising antibodies. Preclinical testing of different human or humanised antibodies in suitable hamster models with the respective SARS-CoV-2 VOCs was successfully performed as a first step towards the development of SARS-CoV-2-VN HuMabs for clinical use.

Key area

  • Antiviral strategies: agents and vaccines, antibodies

Who is involved?

  • Prof. Dr. Albert Osterhaus (Project leader, TiHo)
  • Prof. Dr. Ulrich Kalinke (TWINCORE)

What is the aim?

The main objective is to individually test SARS-CoV-2 neutralising human monoclonal antibodies (VN-HuMabs) in their ability to prevent SARS-CoV-2 lung infection and clinical disease upon preventive and post-exposure administration in a hamster model of SARS-CoV-2 infection. This is a first step towards the development of SARS-CoV-2 VN HuMabs for clinical use.
