It was named for Max Delbrück, a physicist, biologist, and Nobel Prize winner. Currently the institute employs more than 1600 people from nearly 60 countries; over 1300 of those are directly involved in research. The MDC's annual budget is over 80 million Euros, along with substantial third-party funding obtained by individual scientific groups. As is the case with all Helmholtz institutes, the MDC receives 90 percent of its funding from the federal government and 10 percent from Berlin, the state where it resides. About Heidelberg Pharma's proprietary ATAC technology Antibody drug conjugates (ADCs) combine the high affinity and specificity of antibodies with the potency of cytotoxic small molecules for the treatment of cancer and inflammatory diseases. ATACs are ADCs that are bound to highly potent amatoxin molecules. Amatoxins are small bicyclic peptides naturally occurring in the death cap mushroom. They inhibit mRNA transcription by binding to RNA polymerase II, a mechanism that is crucial for the survival of eukaryotic cells. In preclinical testing, ATACs have been shown to be highly efficacious, overcoming frequently encountered resistance mechanisms and combatting even quiescent tumor cells. About WILEX and Heidelberg Pharma WILEX AG is a biopharmaceutical company based in Munich, Germany, that serves as a parent and holding company. The Company's research and development work is conducted by its subsidiary Heidelberg Pharma GmbH in Ladenburg. Heidelberg Pharma is the first company to develop the toxin Amanitin into cancer therapies using its proprietary Antibody Targeted Amanitin Conjugate (ATAC) technology and to advance the biological mode of action of the toxin as a novel therapeutic principle. This proprietary technology platform is being applied to develop the company's own therapeutic ATACs as well as in third-party collaborations to create a variety of ATAC candidates. The proprietary lead candidate is a BCMA ATAC for multiple myeloma. WILEX's clinical assets MESUPRON(R) and REDECTANE(R) have been partnered, while RENCAREX(R) is available for out-licensing and further development.
