How to Conduct a Veterinary Clinical Study
Run a study in the target species, where the owner consents and the food chain is in scope.
What a how-to is not
A how-to is SPEQ’s practitioner method, not a procedure. It does not replace your own SOP, it is not a validated approach, and the judgement calls in it belong to your quality unit.
Veterinary good clinical practice governs studies of veterinary products in the species the product is intended for. It is a distinct standard from human clinical practice for structural reasons, not stylistic ones: the subject cannot consent, the owner or producer can, and where the animals are food-producing the study has to protect the human food chain as well as the animal. Applying human trial assumptions here produces a study that is well run and non-compliant.
- 1
Define the target species, class and use conditions
The study must be conducted in the species and class the product is intended for, under conditions of use that resemble the intended ones. Evidence generated in a convenient species or under artificial husbandry does not support the claim being sought.
- 2
Obtain the owner’s or producer’s informed consent in writing
The consent runs to the animal’s owner or keeper, and it must cover the study procedures, the obligations placed on them, and any restrictions on the animals afterwards. Companion-animal owners and commercial producers need materially different explanations of the same study.
- 3
Address animal welfare and the ethical review the study requires
Welfare is a design constraint, not a compliance annex: humane endpoints, pain management, and the criteria for withdrawing an animal are specified before the study starts. Independent ethical review is expected, and its scope covers the animals and the personnel handling them.

Protect the human food chain where food-producing animals are involved
Establish withdrawal periods and the disposal or restriction rules for milk, eggs, meat and tissues from treated animals, and evidence that they were followed. This obligation has no equivalent in human trials, and it is the one most often underestimated by teams arriving from that side.
- 5
Assign and document the investigator and monitor responsibilities
The investigator is responsible for study conduct at the site and for the animals in it; the monitor verifies conduct against the protocol. Roles, delegation and qualifications are documented as they are in human trials, and the record has the same evidential purpose.
- 6
Record adverse events in the treated animals and in exposed people
Adverse events cover reactions in the treated animals and in humans exposed through handling or administration. A safety record that captures only the animals misses a category the standard explicitly includes.
- !Human trial assumptions carried across, so consent, welfare review and food-chain obligations are mis-scoped.
- !Study run in a convenient species or under husbandry conditions unlike the intended use.
- !Withdrawal periods set but not evidenced, leaving no proof that treated product stayed out of the food chain.
- !Human exposure during handling or administration omitted from the safety record.
How to Conduct a Veterinary Clinical Study: frequently asked questions
Common questions on conduct a veterinary clinical study.
Who gives consent in a veterinary study?
The animal’s owner or keeper, in writing, after being told what the study involves and what it requires of them. For a companion animal that is an individual owner; for food-producing animals it is the producer, whose obligations extend to withdrawal periods and product restrictions after treatment.
Why can a human clinical practice standard not be used instead?
Because the structural facts differ. The subject cannot consent, welfare and humane endpoints are design constraints, the study must run in the target species under realistic use conditions, and food-producing animals bring an obligation to protect the human food chain. A study run to human trial standards can be rigorous and still fail on all four.
What safety information has to be captured?
Adverse events in the treated animals, and also adverse reactions in people exposed to the product through handling or administration. Human exposure is a defined part of veterinary safety reporting and is routinely omitted by teams who think of the animals as the only subjects.
