In short
In vivo toxicology should be designed around a clear safety question, justified dose selection, appropriate observations, predefined stopping criteria and transparent reporting. Manna Biotech supports suitable non-clinical toxicology workflows subject to feasibility, facility scope and required approvals.
What a defensible toxicology study needs
- A defined safety question and test-article identity
- A scientifically justified dose range
- Appropriate control groups
- Predefined clinical observations and stopping criteria
- Planned sample collection and laboratory endpoints
- Transparent documentation of deviations, exclusions and interpretation
Dose planning and preliminary evidence
Dose selection should be based on the available evidence and the purpose of the study rather than chosen arbitrarily. Existing in vitro, formulation, chemical or prior non-clinical information can inform the design where appropriate.
Safety endpoints and reporting
- Clinical and behavioural observations appropriate to the model
- Body-weight or intake measurements when relevant
- Biochemical, haematological or histological endpoints where planned
- Molecular endpoints where they address a defined safety question
- Clear reporting of methods, observations, limitations and interpretation
Ethical and facility requirements
Non-clinical toxicology involving animals must proceed only after scientific feasibility, facility suitability, welfare requirements and the applicable approvals have been established.
Frequently asked questions
Does Manna Biotech support in vivo toxicology research?+
Manna Biotech supports suitable non-clinical toxicology research workflows subject to scientific feasibility, facility scope and required approvals.
Is OECD 423 part of this area?+
OECD 423 is one recognized acute oral toxicity framework. The exact study approach must be selected according to the research or regulatory objective and applicable requirements.
Can toxicology be combined with biochemical or histological analysis?+
Yes, where those endpoints are scientifically justified and included in the approved study design.
Does Manna Biotech guarantee a safety classification or regulatory outcome?+
No. The research workflow can support evidence generation and interpretation, but regulatory or biological outcomes cannot be guaranteed.
