3ROCKIT
3ROCKIT stands for Replace Reduce Refine Organismal Research by Computational and Cellular technologies@KIT. Research groups at KIT develop novel in vitro and in silico technologies to ultimately replace animal studies and methods for personalized medicine, the development of biomaterials and for automated and intelligent surgical assistance and for future autonomous interventions.
Heading towards the next-generation 3R Centers
Today, the enormous development in the health technologies sector would not be possible without interventions and tests in living organisms. To analyze the effects of novel technologies, drugs and implants inside the body in health and disease and to transfer this knowledge into the clinic, conducting research on living organisms is therefore still indispensable. Today, the 3Rs, Reducing, Replacing and Refining the animal research, are reflecting the awareness and responsibility of scientists and society towards a more ethical use of animals in product testing and scientific research. At KIT we have strongly committed ourselves to the 3R principles by using non-animal research wherever it is possible and by encouraging technology development of alternative methods. In the last years we set up a Research Field on “Lifescience Technologies” and funded the KIT Center "Health Technologies" with a strong focus on in vitro and especially on in silico alternatives to animal testings and the research on digitalized process technologies for the accelerated transfer of these these alternatives to the market.
With the FDA Modernization Act 2.0 in effect and the European Parliament adopting a new resolution to phase out animal testing, the need for a transition is more pressing than ever. At KIT, we're fully committed to advancing our research in animal replacement technologies by using digital methods and the emulation of the digital patient and multi-level twins. In addition, we will focus our research on alternative technologies and the digital process development to accelerate the transfer of alternative technologies and innovations to the market. This innovative approach leverages intelligent technologies and deep neural network algorithms to deliver highly precise results in significantly shorter timeframes along with the severe reduction of the animal numbers. Our flagship 3R Center, 3ROCKIT, encompasses six Core Units, which are all dedicated to promote research on alternatives to the wellbeing of animals and humans by building up highly valuable training datasets for the "Virtual Human Twin", by carefully validating our technologies and by promoting innovation transfer.
Computational models and artificial intelligence, also known as in silico models, present an additional avenue for reducing reliance on animal testing. In silico models encompass various techniques such as structure-activity relationship assessments, which compare how different chemicals affect cellular functions. They also include software predicting a chemical's potential actions or adverse effects based on its structure, as well as physiologically-based models providing insights into biological distribution and effects through mathematical derivations of tissue entry or exit rates. Furthermore, artificial intelligence and deep learning methodologies, involving computer-based simulations aimed at mimicking human organ functions, are being developed to generate study results for new compounds based on existing data, thereby potentially eliminating the need for animal testing. AI can also support the design of in vitro based models replacing animal experiments to understand the microphysiology in health and disease.
If animal experiments are absolutely necessary only the minimum number of animals to achieve a significant result should be used. This can be achieved by smart experimental design, technological optimization and data sharing with other scientists.

Experimental conditions are being constantly optimized in order to significantly reduce the burden of the animal. This can be done by reducing stress during long term experiments, using anaesthetics against pain, and providing a modern husbandary etc.
The 6R Principle
Apart from the widely recognized 3Rs (Replacement/Reduction/Refinement), a conscientious culture in animal research encompasses three additional principles: A statistically robust experimental design (Robustness), the registration of all experiments (Registration) and the publication of negative results (Reporting). At KIT we are dedicated to implement the additional R's (Robustness, Registration, and Reporting) in our guidelines for animal research. This includes the following meseausures:
(1) Conceptualization of the benchmarks of robustness
(2) Setting up guidelines for registration of mandatory information
(3) Introducing an ELN for the results that allow the storage of all reported results
(4) Installing a committee for auditing 6R compliance.
With the help of our proprietary electronic lab notebook (labImotion) that supports the storage of all data from animal experiments in a repository using a doi for findable and easily accessible data we are dedicated to share and published complete data sets.
In vivo preclinical studies are still mandatory and strictly regulated for most health technology approvals. They are required by law to ensure a proper risk assessment of the devices, therapies and diagnostics and are allowing the maximum protection of the patient’s health. At the PreClinical Research Center at 3ROCKIT we are highly committed to conduct all studies according to the 3R principles whenever it is possible. To fullfil a long-term perspective on reducing animal studies the PreClinical Research Center supports this 3R research by operating a validation pipeline for alternative methods to make future health technology research more reliable and animal friendly.

Many in vitro pharmacological test systems and engineered tissue replacements especially in personalized medicine applications require the use of patient derived biopsies, primary cells or stem cells so-called induced pluripotent stem cells (iPS) that are are capable of giving rise to an infinite number of other cells. At BioBanK we store biopsies, primary cells and iPS cells from patients acquired through our collaboration with the different stakeholders from KARE for applications in innovative health technologies research.

The 3D-reconstruction of tissues either for all kinds of preclinical testings or for human organ/ tissue replacements is becoming one of the disruptive technologies that besides the digitalization will have an enormous impact on health Technologies of the future. Tissue reconstruction requires a highly interdisciplinary team of scientists from biology, chemistry, engineering to data science and market analysts and platform technologies such as tissue culture automation and imaging facilities. At 3ROCKIT the tissue model unit will serve as an enabler by providing expertise in all kinds of 3D tissue generation.

Creating a Virtual Human Twin across all scale is a unique possibility to replace many animal experiments according to the 3R Principles. At the Virtual Human Twin Core Unit we develop all kinds of AI-supported methods for the computational modelling of small units such as cell distribution and cell fate in biopsies to microenvironments in tumors and organoidsor even larger entities such as whole organs such as the heart and establish trained machine learning models of dynamic models such as body fluid flow and gas exchange. Our expertise is comprising technologies from computational image analysis, 3D tissue modelling, biomechanics modelling, molecular biodiversity to BioMedical Data Science.

Medical imaging and image processing plays a central role in medical diagnostics and therapy. Multimodal data from a wide variety of imaging methods, large data volumes due to increasingly higher image resolution and three-dimensional images are just some of the challenges faced by doctors in differential diagnostics. At the Tissue Imaging Core we are providing you with a broad expertise on tissue imaging and image data processing ranging from high resolution and high throughput microscopical imaging to NMR, X-ray and sophisticated MRI and ultrasound technologies.
