In silico (QSAR) consulting and training solutions that fast-track innovation and compliance
Leveraging two decades of CEHTRA’s regulatory expertise, we deliver cutting-edge in silico toxicology and QSAR training solutions to support Human Health, Ecotoxicology, and Environmental Risk Assessment.
Next-Gen Toxicology Insights.
No Animals. Just Science.
We deliver expert-driven predictions using advanced in silico New Approach Methodologies (NAMs), notably QSAR models & Read-across to help you meet global regulatory requirements efficiently and ethically.
REACH-compliant in silico predictions, supported by comprehensive documentation (QMRF, QPRF, and QAF)
In silico risk assessment for cosmetics (CPSR), to support safe ingredient selection and regulatory compliance
Mutagenicity assessment of impurities for ICH M7 compliance, using expert rule-based and statistical QSAR models
Read-across (Bridging) and in silico predictions to address data gaps for regulatory submissions.
Toxicological profiling of active substances and co-formulants in crop protection products and agrochemicals
In silico evaluation targeting EATS modalities (Estrogen, Androgen, Thyroid, and Steroidogenic receptors)
In silico predictions to support the risk assessment of food and feed substances, including novel proteins and peptides
In silico toxicology assessment (including CMR endpoints) of cosmetic packaging and food contact materials
In silico toxicological assessment of medical devices based on structural alerts and QSAR modeling
Unlock the full potential of in silico models
Your shortcut to smarter submissions
A smart way to save time, cut costs, and streamline resources for your R&D and regulatory needs.
​Driving the Future of Non-Animal Testing
Increasingly used in the context of New Approach Methodologies (NAMs), Next Generation Risk Assessment (NGRA), and the 3Rs principles (Replacement, Reduction, and Refinement of animal testing).
Compliant by Design
Recognized by regulatory authorities, including for dossier submissions to ECHA, EFSA, as well as in the context of ICH M7 for pharmaceuticals and cosmetic regulations.

Why choose Simply Predict?
Combined expertise
for a decisive strategy
Our QSAR specialists select and apply the most fit-for-purpose battery of models, while our regulatory experts validate the overall strategy and ensure the conclusions are compliant and robust.
100% non-conflicted and
unbiased solutions
We do not develop in-house prediction models, nor do we promote a preferred list of tools or developers. Instead, we curate the most suitable in silico models from a broad range of available solutions—tailored case by case to best meet your needs.
Timely Support
You Can Rely On
We strive to respond to all standard inquiries within 2 business days.
