Our mission is to
Assess the health effects of compounds
without the use of animal tests
We can help you with
Developmental and Reproductive Toxicology (DART)
Adverse Outcome Pathways (AOPs)
Compounds of Unknown or Variable Composition, Complex Reaction Products and Biological Materials (UVCB Substances)
At Vivaltes we believe in reducing animal research to carry out toxicological and medicinal studies.

Our service pipeline supports more humane animal research and aims to reduce the cost of animal testing. We do this by introducing a Tier-1 phase of testing where animal-test free experimental models are used.
This follows the principle of 3Rs by the NC3Rs: Replacement, Reduction and Refinement.
While in vitro tests are an attractive alternative for animal testing, they can never replace full body effects of chemicals. In living organisms, cells and organs in the body communicate to each other, for example by hormones or other signalling molecules.
Additional 3R tests therefore include in vivo test systems, small organisms, like the 1-mm sized nematode Caenorhabditis elegans.
Our strategy allows us to pre-screen large amounts of compounds in a high-throughput fashion, to select the most promising compounds for product development pipelines. In addition, we can gain insight in how compounds cause their effects, in order to help to improve compound/drug design procedure.
The Experimental Model
Vivaltes’ core strength is the experimental model organism C. elegans, a 1-mm long transparent nematode.
These animals fall outside the definition of animals included in the animal testing law, and are thus considered animal test-free.
C. elegans was first used as a model organism in 1963 and the acquired knowledge made an invaluable contribution to the fields of developmental biology and genetics. The application of C. elegans in the field of toxicology is rising, evident from the increasing number of publications.
The C. elegans body plan
- C. elegans is a multicellular organism, it has neuronal, motor, digestive, and reproductive systems, endocrine signaling, and sensory/behavioral responses to stimuli, which are not present in cell and tissue cultures.
- The organism has been studied for over 55 years, there is thus a large body of knowledge to make use of.
- Humans and C. elegans have a common ancestor, many key pathways are conserved.
- The ease of handling allow multiple concentrations and exposure times to be assessed simultaneously.
- The rapid lifecycle allows for low-dose lifespan and multigeneration testing in a couple of weeks rather than years.
- Multiple types of toxicity ranking screens have demonstrated good correlation of endpoints in C. elegans to rat LD50s, with C. elegans data and mouse data predicting toxicity ranking in rat equally well.

Save the Date!
February 17, 2020
Save the Date! On May 15, 2020, Vivaltes together with Schenkeveld, Ockham, Greenport, and the NH Food team are organizing the Novel Foods event that takes place in Alkmaar. The speakers are experts of novel foods, test methods. and laws and regulations. The knowledge event is for farmers, horticulturists, seed breeders, developers of new foods and other professionals including regulators who are involved in novel foods.
Health benefits of Traditional Chinese Medicine
January 22, 2020
We’re very excited and proud! How does Traditional Chinese Medicine (TCM) work? Vivaltes and SU BioMedicine are collaborating to modernize herbal medicine, combining technology from the West with wisdom from the East. This project is supported by Provincie Noord-Holland, which is great!
Vivaltes is Sponsor of 12th Annual Global Discovery to Development Innovation Forum
May 10, 2019
The Annual Global Discovery to Development Innovation Forum (GDDIF) is the leading pharmaceutical Research & Development summit for pharma decision makers, scientific leaders, and solutions experts. Meet us there 14–15th May 2019!
NC3Rs Crack-It Phase II started
January 15, 2019
A consortium of academic institutions and SMEs (among which Vivaltes) has received £1 million from the NC3Rs to deliver Phase 2 of the DARTpaths CRACK IT Challenge. This project is led by Professor Raymond Pieters.
Hot peppers: a new weapon in the fight against obesity?
December 8, 2018
Hot peppers contain a substance that causes you to burn more fat. In that way, one can continue to eat the same and still lose weight. In America a medicine is being made from hot peppers. Dutch researchers want to make a food supplement or even a whole new pepper variety. Vivaltes is working on the subject with a team of researchers.
October 15, 2018
The goal of the TOX FLOW project is to set up a test method for animal test-free testing of effects of complex substances on reproduction and development (also called developmental and reproductive toxicology (DART)). Partners in this project are HU, IRAS-UU, WUR, RIKILT, Pamgene.
NC3Rs Crack-It Phase I
January 1, 2018
Vivaltes and collaborators obtained funding from NC3Rs to develop a proof-of-concept for DARTpaths CRACK-IT challenge to map developmental and reproductive toxicity (DART).
