At present, the treatment for brain tumors is surgical removal. For now, the development candidate must first meet these expectations in further clinical studies. As this structure does not occur anywhere else in healthy cells of the body, we are expecting the drug candidate to be especially well tolerated,” explains Kaulfuss. Antibody-drug conjugates are particularly promising candidates. It paralyzes the DHODH enzyme that is important for biosynthesis. At the same time, however, it must be able to be cleaved later inside the lysosomes within the tumor cells so that the cell toxin can exert its action there.It will take some time until the most recent projects by Lerchen and his colleagues are ready to be marketed. Bayer is growing its prostate cancer portfolio with an androgen receptor inhibitor (ARi) for the treatment of non-metastatic castration-resistant prostate cancer (nmCRPC). What genetic and immunological changes led to the disease? Technician Seren Nesan prepares syringes to take blood samples from study animals in a Berlin laboratory.The first and most important prerequisite for precision therapy is that the physician must be thoroughly familiar with the patient’s tumor.Today, cancer drugs come from five major categories: small molecules, antibody therapies, cellular therapy, chemotherapy, and radiopharmaceuticals. Bayer provides free access to study plans and to results of clinical studies on several publically accessible Clinical Trial Registries on the internet. If these individual tumor biomarkers were to be identified, it would be possible to offer patients treatment that is tailor-made for their specific tumor. Adds Hägebarth, “I can imagine that in the long term we will even be able to cure some forms of cancer. certain proteins that play an important part in cancer-specific processes, known as oncogenic signaling. The approval of Vitrakvi means that certain types of highly advanced solid tumors that are metastatic (spreading), unable to be surgically removed and do not qualify for other treatments can now be effectively treated. The approval reflects a development in cancer treatment drugs away from body location-specific medicine to treatments based on genetic defects and mutations. It is the first commercial medicine for Loxo, a Connecticut company that develops treatments for genomically defined cancers. Research in this complex field is fraught with setbacks. These methods can be very successful in certain cases, but they also have limitations.“The fibroblast growth factor activates a signaling pathway that is important for the growth of normal cells, but also of tumor cells, via four different FGFRs,” says Ellinghaus. To illustrate why, Lerchen sketches the structure of a conjugate: antibody – linker – drug. So far, however, no research team has succeeded in finding suitable antibodies by means of which the FGFR proteins could be identified sensitively in the tumor.With many brain tumors we find a specific mutation in a particular enzyme.Biomarkers enable us to find out which patients could benefit from the active substance in question.“In many brain tumors we find specific mutations in a particular enzyme called isocitrate dehydrogenase (IDH),” explains Dr. Stefan Kaulfuss, senior scientist in the Oncogenic Signaling department. the individual tumor. That will play a very major role in particular for the condition of earlier diseases and residual diseases, i.e. Despite recent advances in nmCRPC treatments, there remains a unmet need for new therapeutic options that not only delay the time to metastases, but also have a favorable safety profile, which is important for these patients as …
And my parents always supported this path, which began when we set up a chemistry laboratory in our basement,” says Lerchen. Benefit: New Bayer drugs could help patients with brain tumors, acute myeloid leukemia and other forms of cancer in the future. The Challenge: Cancer drugs often have severe side effects because they attack not only the tumor but also other cells in the human body. Cancer researchers like us still have many things left to discover and questions to answer.”Every tumor is different. Learn more about Bayer and the opportunities available.In addition to the already approved indications, the use of rivaroxaban is also being investigated in other cardiovascular diseases such as prevention of major adverse cardiac events, embolic stroke of undetermined source or peripheral artery disease.Lab assistant Carolin Geier examinating round worms in a lab in Monheim.Bayer is the only global company simultaneously researching improvements in human, animal and plant health.
