Animal welfare

TAG overview

International and national legislation mandate animal testing of medicinal compounds and chemicals during their development and prior to their approval for commercial use. In addition, from an ethical and scientific perspective, animal research is indispensable based on the current state of knowledge. We perform animal-using activities in all three of our business sectors.

Our approach to animal welfare

Our long-term aspiration is to be a pioneer in phasing out animal use and replacing animal work with better, cutting-edge alternatives. We aim to outperform as the leader in non-animal-derived products and testing in the life science and healthcare industries. Our business sectors develop individual strategic roadmaps, priorities and timelines towards this aspiration.

Animal testing will be an unavoidable necessity for many more years, especially in drug development to ensure the safety and efficacy of medical devices, medicines and vaccines. As long as animal usage cannot be completely avoided, we are committed to applying the highest ethical and animal welfare standards related to the housing, husbandry and veterinary care of all animals involved in our work. We ensure comprehensive transparency and ongoing assessment, monitoring, auditing, and improvement of all work involving the use of animals by our company and by trusted third parties. We continuously improve our animal testing processes, striving to enhance the animals’ quality of life. We always use as few animals as possible and replace their use whenever feasible with alternative methods. In addition, we advocate for the global acceptance of replacement methods. To this end, we join forces with industry and academia.

We subscribe to the internationally recognized 3Rs for animal-based research and have added Responsibility as our fourth animal welfare principle in line with the ethical considerations published in 2019 by David DeGrazia and Tom Beauchamp in Principles of Animal Research Ethics:

  • Replacement – replacing animal studies with non-animal systems
  • Reduction – using the minimum number of animals required
  • Refinement – minimizing distress or discomfort before, during and after testing
  • Responsibility – accepting responsibility for all animals in our reach internally and among our business partners

Within our Life Science business sector, animal activities include required regulatory safety testing of our own products and on behalf of customers. The Life Science product portfolio also includes various materials needed for research that are derived from animals or by-products from food production, such as blood, plasma, or serum, or items specifically produced in animals, such as antibodies. Our Healthcare business sector conducts animal testing as a mandatory part of the drug and medical devices development process and conducts biological quality control in animals. Our Electronics business sector conducts animal tests as required by applicable chemical regulations. In line with the EU Cosmetics Regulation, no animal tests are conducted for cosmetic ingredients.

Roles and responsibilities

Our Corporate Animal Affairs unit governs the implementation of the Corporate Animal Welfare strategy. The unit acts globally and locally, setting and overseeing guardrails for the use of laboratory animals based on four pillars:

  • Animal Welfare
  • Animal Using Vendor Management
  • Vivarium Oversight
  • The 4R principle

Our Group Animal Welfare Council, sponsored by the CEO of our company, comprises representatives from all business sectors and meets quarterly. The council acts as sounding and advisory board, assessing which of our services and product innovations can help to avoid animal testing in the future. Moreover, it consults on business-critical issues, adopts key indicators and serves as an escalation body.

In 2022, we established the Group´s Animal Usage Review (MAUR) boards in Europe by utilizing existing internal decision-making animal welfare bodies that review and approve all internal animal work conducted by our vivaria, where available. In the United States and Israel, these tasks are performed by already existing comparable company-owned boards such as the Institutional Animal Care and Use Committees (IACUC, in accordance with the U.S. ILAR Guide). In addition, these global MAUR / IACUC boards now also review and approve any animal-based activities at all our vendors, contract research organizations and academic partners.

Global and local animal welfare officers supporting the local business report directly to Corporate Animal Affairs and are advocates of the animals. Their tasks entail animal science and welfare management as well as acknowledging the individual skills and abilities of all personnel working with animals. Furthermore, they regularly inspect the animal facilities as well as review and approve protocols.

The Animal Using Vendor Management unit qualifies our suppliers with regard to animal science and welfare. The group also continuously monitors our contract research organizations, suppliers and business partners.

If employees identify an issue regarding animal welfare, they can report it directly to Corporate Animal Affairs, to local and global animal welfare officers or via our compliance hotline.

The 4R team and cross-functional workstreams develop and guide projects to implement our 4R principles. The 4R team regularly reports progress made with the 4Rs to the Group Animal Welfare Council. It also coordinates the 4R Award, with which we recognize contributions to the Replacement, Reduction, Refinement of, and Responsibility for our animal work.

Comprehensive employee training

With our new Animal Affairs Academy, we define a holistic training concept for our entire company, provide training sessions on animal welfare, and oversee and provide staff training on practical work, rules and regulations. All employees involved in animal activities receive appropriate training and continuing education. For example, through our Vivarium Rotation Program, employees of each of our vivaria visit another vivarium every year to exchange knowledge and share best practices. The program has been successful, and the University of Heidelberg in Germany has expressed its interest in collaboration.

Additionally, our employees regularly participate in external continuing education programs.

Work with committees and associations

As part of our efforts to improve animal welfare, we are involved in several organizations and initiatives, including the European Federation of Pharmaceutical Industries and Associations (EFPIA) and Interpharma, a federation of research-based pharmaceutical companies in Switzerland. Interpharma conducts audits at contract research organizations and animal breeders together with selected member companies.

We are a member of the European Animal Research Association (EARA), a communications and advocacy organization representing both public and private institutions in the biomedical sector. We are also involved with the Association for Assessment and Accreditation of Laboratory Animal Care International (AAALAC). This private, nonprofit organization promotes the humane treatment of animals in science through voluntary accreditation and assessment programs. In 2022, one of our employees served as the chair of the AAALAC International Board of Directors.

Our commitment: Group-wide standards

Beyond compliance with all applicable laws and regulations, we are committed to our own set of internal guidelines. Our Animal Affairs Policy, our Group animal welfare standards and our procedures for animal testing conducted internally and by trusted third parties corroborate a comprehensive and stringent governance framework based on our four pillars of animal use governance.

Our standards and procedures entail, for example, the housing and husbandry standards that also apply to external partners, and how we monitor them, including audit procedures. The Animal Using Vendor Management standard describes the requirements for the approval of contract research organizations and suppliers. Further documents, including guidance for our 4R efforts, incident reporting and risk management, augment the governance framework. In 2022, we implemented further company-wide standards such as the Global Blood Sampling Standard (GBSS), which defines parameters and methods for blood collection, maximum blood sampling frequencies and volumes in a given time frame. We are convinced that the right level of transparency has the potential to improve the scientific outcome and value of animal testing and creates benefits for society, patients and animal well-being. After joining the German Transparency Initiative in 2021, we were awarded the Seal of Quality for Best Practice in Animal Research communication particularly for our achievements in communicating transparent and open about animal experiments in research.

Number of laboratory animals used for medical study purposes

In 2022, a total of 149,643 animals were used within the scope of our business activities, either in our own vivaria or on the premises of organizations contracted on our behalf. This represents an overall decrease of 17% compared with 2021. Rodents (mice or rats) comprised 144,941 of all animals used in 2022, compared to 175,522 in 2021. Regulatory agencies sometimes require studies of the safety of investigational drugs in non-rodent species. This allows researchers to identify potential adverse effects accurately and include them in the risk assessment of a substance.

Collaborating with partners and suppliers

We perform the majority (94%) of our animal studies ourselves and procure the required animals from specialized breeders. We also commission contract research organizations to conduct animal studies on our behalf. Furthermore, we work with academic institutions. Whenever we collaborate with such organizations, we require them to comply with our standards.

Conducting animal welfare audits

Corporate Animal Affairs conducts an audit of each of our vivaria every three years. In 2022, two vivaria were audited. Furthermore, we improved Corporate Animal Affairs’ oversight of internal animal work regarding aspects such as animal usage, purpose and incidents. In the reporting year, we implemented a digital solution that monitors our key indicators.

An integral part of our strategy is the qualification of all animal-using vendors we conduct business with. We completed the implementation of an auditing strategy and developed procedures to identify and train auditors. In 2022, a total of 45 vendor audits were performed, 38 of them on-site and 7 virtually due to the Covid-19 pandemic.

4R Award for animal welfare

We aim to motivate all our employees to contribute to the 4R principle. Therefore, with our biannual 4R Award, we recognize best practices in animal work, such as pioneering better solutions to Reduce, Replace or Refine or leading by example in Responsibility.

Our annual 4R Day in 2022 focused on the new Corporate Animal Welfare strategy and gave an overview of current 4R activities, highlighting company-wide project submissions representing each of the 4R categories. The grand prize was split evenly between two outstanding projects representing the Replacement and Reduction categories.
