How Metaphors shape Biotechnology Meeting

Nov 24, 2023 - Biotechnology meets Philosophy

The truly interdisciplinary workshop "How Metaphors shape Biotechnology" brought together Biologists and Philosophers to discuss the impact of the metaphors on biosciences. Scientific research uses metaphors to guide the perception of research itself (epistemological capacity of metaphors) and to frame public science communication (discursive capacity). The use of Metaphors is essential to describe previously unknown biological phenomena and formulate hypotheses. The choice of a particular metaphor may well bias the researcher's thinking, and thus influence the direction of future reserach, since it always never exactly matches the true biological phenomenon. Metaphors are also essential to convey scientific results to a wider public, thus shaping the public perception and affect their acceptance or repudiation.

West Nile Virus
Electron micrograph of the West Nile Virus

Sept 12, 2023 - Therapeutic antibodies and vaccines against West Nile virus

West Nile virus is transmitted by mosquitoes and is becoming increasingly prevalent in Europe, partly as a result of global warming. Infection with West Nile virus leads to encephalitis (inflammation of the brain) in about one in 100 infected persons, with about half of the patients suffering from late sequelae and cicra 10 percent of the patients die. So far, there is neither a specific therapy nor a vaccine against West Nile virus. Here, the TU Braunschweig will work together with partners in Spain, France and Denmark on new therapies and vaccines against this virus within the framework of an EU Horizon 2020 project.

Mutation positions (red) in the RBD of SARS-CoV-2 Omikron Spike Protein

Dec 17, 2021 - ABCALIS diagnostic/research antibody against anti-SARS-CoV-2 Spike Protein S1 (RBD) binds to Omikron

The phage display derived antibody AB68-A09 made by Abcalis shows the same detection sensitivity for Wuhan, Delta and Omikron variants of the spike protein. The antibody was generated with animal free methods (i.e. without an immunisation of an experimental animal, and with production methods that do not use animal materials) by recombinant means and detects the receptor binding domain of the COVID-19 causing virus SARS-CoV-2.

The antibody is available here


Braunschweig , Dec 10, 2021 / Jan 11, 2022 - Boost immunizations help against Omicron

After vaccination against the coronavirus, our body produces antibodies that contribute significantly to protection against COVID-19. The amount and strength of binding of these antibodies to the new omicron variant and the efficiency of different vaccination combinations have been investigated in two different studies by a team of researchers from the Technical University of Braunschweig together with partners from the EU consortium ATAC (Antibody Therapy Against Corona), as well as the Helmholtz Centre for Infection Research and the University of Rijeka. The results contribute to a better understanding of the spreading properties of the virus, and show that boost immunization increases the number of antibodies against the envelope protein of SARS-CoV-2 in all virus variants studied, including the new omicron variant. Important findings also relate to boost immunization following dual vaccination with the Sinovac or Sinopharm inactivated vaccines commonly used outside of Europe.

An important and somehow surprising finding of the first study is  that the Omicron variant of the spike protein bound the cell surface receptor less efficiently than the currently circulating virus (see figure). On the other hand, both COVID patients and vaccinated persons have reduced antibody responses against Omicron. This suggests that 15 mutations present in the Omicron RBD are there rather to allow the virus to escape recognition but not to infect cells more efficiently.

Braunschweig, Jan. 11, 2022 - Worldwide study on efficacy of cross-vaccinations

In a second study, serum samples from COVID-19 convalescents and people immunized with mRNA vaccines (BioNTech, Moderna) or inactivated vaccines (Sinovac, Sinopharm) were examined. It was shown that the amount of antibodies in the blood against the envelope protein of SARS-CoV-2 started to decrease about three months after the second vaccination. However, boost immunization again increased the amount of specific antibodies, even to higher levels than immediately after the second vaccination. This could be shown for all four virus variants of concern (VOC): the original Wuhan variant, as well as Beta, Delta and Omicron. For the Wuhan variant, the number of immune cells (B and T lymphocytes) reacting against the virus was also determined. Here again, boost immunization resulted in an impressively improved immune response. The highest antibody levels were found in triple mRNA vaccinated and – most important – also in those vaccinated first with an “inactivated vaccine” and then boosted with an mRNA vaccine.

Braunschweig, Sept 6, 2021 - Substantial support for CORAT Therapeutics by the German federal government

Federal Secretary of Research Anja Karliczek and Federal Secretary of Health Jens Spahn announced today the funding of CORAT through the programme "Clinical Development of Care-Related COVID-19 Drugs and Their Manufacturing Capacities" by BMG and BMBF.

Federal Research Minister Anja Karliczek explains: "For several weeks now, the delta variant of the SARS-CoV-2 virus has clearly shown us that we will unfortunately have to expect that people will continue to fall ill with COVID-19 in the future. Even with widespread availability of COVID-19 vaccines, not all people will be able to receive vaccination. Therefore, more effective drugs are needed to treat the ill."

Federal Secretary of Health  Jens Spahn stated:
"At the moment, only vaccination against Corona helps. But we also want to take the horror out of the pandemic in the long term. That's why we are supporting the development of new drugs so that we can continue to treat Corona patients well in the future. And we are investing in the future because in doing so we are also strengthening Germany as a biotechnology research and development location."

COR-101 blocks SARS-CoV-2 Spike

Braunschweig, Germany, June 22, 2021 - CORAT antibody COR-101 binds and inhibits all B.1.617 SARS-CoV-2 variants, including the fast proliferating “delta” variant

The newest laboratory tests indicate that COR-101 binds and inhibits the particularly aggressive new „delta” variant B.1.617.2, which is rapidly replacing the “alpha” variant B.1.1.7. On May 10th, the WHO classified the B.1.617.2 SARS-CoV-2 variant, first detected in India, as “of concern”. According to current data from the European Centre for Disease Prevention and Control (ECDC) the “delta” variant B.1.617.2 has replaced previous SARS-CoV-2 variants, including the “alpha” variant B.1.1.7, currently prevalent in Germany. According to ECDC analysis, the mutations likely increase transmissibility and decrease neutralization by convalescent plasma and currently approved therapeutic antibodies, explaining the sharp increase in the number of cases in India in recent weeks. The currently used vaccines obviously have different efficacies against the newly emerging variants. Also, while vaccines can protect healthy people, they cannot cure people already suffering from COVID-19; moreover, not everyone responds to vaccination. For these patient groups, CORAT Therapeutics GmbH is developing a drug that has an effect against SARS-CoV-2 directly.

4/23/2021 - First COVID-19 patients treated with COR-101 drug developed in Braunschweig, Germany.

Effective drugs against COVID-19 remain scarce in the current coronavirus pandemic. Even though the focus for months has been primarily on enabling rapid vaccination, there will be many people in the future who cannot be vaccinated, for example, due to concomitant diseases, or in whom the vaccination effect fails. Therefore, it is essential to quickly develop specific drugs for the treatment of COVID-19 disease.

The Corona Antibody Team (CORAT) of TU Braunschweig, led by Prof. Michael Hust and Prof. Stefan Dübel, and the biotechnology company YUMAB GmbH in Braunschweig have developed the virus-neutralizing antibody COR-101, which is highly effective against SARS-CoV-2 in laboratory tests. For the clinical development of COR-101, CORAT Therapeutics GmbH was founded with the support of the state of Lower Saxony, which has now started the first clinical trials in collaboration with t the University Hospital of Tübingen. Further clinical study centers are located in Braunschweig, Stuttgart (Robert Bosch Hospital), Leipzig and Dresden. The Phase Ib/II study is being conducted at these sites. In Phase-I, the tolerability of the antibody is initially being investigated in four dose cohorts. Phase II results on efficacy may form the basis for a marketing authorization application for the drug. Initial interim results are expected in the summer.

The antibody COR-101 differs in one important respect from the antibody preparations previously approved in the USA, which were procured by the German Federal Ministry of Health: COR-101 is specifically designed to treat hospitalized moderately to severely ill patients, for whom the U.S. antibodies must not be used because of their side effects. COR-101 avoids these side effects through a different, specially adapted molecular design.

Dr. Bernd Althusmann, Lower Saxony Minister of Economic Affairs, comments: "The promising antibody drug COR-101 shows that research made in Lower Saxony can provide an important building block on the way out of the pandemic. The clinical test phase that started yesterday gives hope that the Braunschweig project can soon save lives."

An international research team of the Technische Universität Braunschweig and the Helmholtz Centre for Infection Research (HZI), led by the Department of Biotechnology of the TU Braunschweig, reported  the development of virus-neutralizing antibodies against SARS-CoV-2 in the journal Nature Communications. These antibodies prevent the viruses from entering host cells and were isolated from an antibody gene library that had already been produced from immune cells of healthy donors before the pandemic. The study shows how, in the future, active substances to previously unknown, emerging viruses can be produced very quickly without the need for patient-derived material.

December 18, 2020 - Human SARS-CoV-2 neutralizing antibody COR-101 demonstrates high efficacy in a COVID-19 animal model and is ready to be used in clinical studies to treat COVID-19 patients

  • COR-101 decreased virus load in the lung by more than 99 %
  • COR-101 induced recovery after 2 days, compared to 7 days untreated

CORAT Therapeutics GmbH today reports the successful conclusion of hamster disease model tests of their lead candidate COR-101 against COVID-19. "Our antibody induced recovery of SARS-CoV-2 infected hamsters within two days. In contrast, without treatment, the hamsters only started to reach the same health status after a full week." comments Dr. Andreas Herrmann, CEO of CORAT Therapeutics.
Treatment with COR-101 substantially reduced the weight loss after infection, which indicates the general health state. But since the main life-threatening effects of the virus are happening in the lung, the virus titer was measured directly in this organ which mainly contributes to lethality of SARS-CoV-2.

Dr. Herrmann says: "We are especially happy to report that COR-101 drastically reduced the amount of SARS-CoV-2 in the lung. Already after three days, an average of less than 1 % of the virus titer of the untreated control group could be detected after treatment with COR-101. This confirms the excellent neutralizing capability that we already measured in the laboratory. It demonstrates that COR-101 efficiently neutralizes the virus in a living organism and prevents disease progression".

In that respect, Dr. Herrmann also emphasized the difference in effector mechanisms compared to other antibodies: "In contrast to plasma therapy and the currently emergency approved antibodies in the US, our recombinant antibody is especially designed not to induce overshooting immune responses which contribute to the lethality in the lung. We achieved this by carefully removing the respective signals from the molecule before starting its production."

How COR-101b locks SARS-CoV-2

4.12.2020 - CORAT today published how COR-101 blocks SARS-CoV-2 and prevents infection with the coronavirus. The fully human antibody COR-101 showed an IC50 of 0.56 nM in a plaque-based live SARS-CoV-2 neutralization assay. The crystal structure of COR-101 in complex with SARS-CoV-2-RBD was solved at 2.0 A resolution showing that the antibody binds at the same region as the human coronavirus receptor ACE2 to SARS-CoV-2-RBD. In contrast to other published anti-SARS-CoV-2 antibodies, the binding of STE90-C11 is not blocked by known virus mutations, endowing COR-101 with higher intrinsic resistance to those possible escape mutants.

CORAT CEO Dr. Andreas Herrmann explains: "We know that a vaccine does not work in every person, and this is especially observed in older people. There are patients with other diseases that cannot be vaccinated as well. Unfortunately, these are precisely the two groups of people who usually have a higher risk of developing COVID-19. This is where COR-101 should help. Since COR-101 permanently occupies the essential contact point between the virus and our body, the virus can no longer use its "spike" proteins to infect us. We therefore expect COR-101 to be able to help all those who already have COVID-19 but whose immune system was unable to initiate its own antibody response."

Unlike the typical vaccines currently under investigation, antibody drugs do not require sophisticated freezing logistics, they are very stable and robust molecules. A century ago, doctors carried vials of antibodies in their pockets for weeks without refrigeration, so that they were always ready for use against tetanus or diphtheria, for example. COR-101 is therefore expected to have much simpler and cheaper logistics for the distribution than RNA vaccines.

With acute case numbers rising fast, CORAT hopes to make a difference by providing an option soon to directly treat the Coronavirus-Infected. We hope that the clinical studies now can commence very soon.“
