• Measures to limit resistance development from the intended use of the product shall be proposed by the applicant.

• The purpose of clinical trials is to demonstrate or substantiate the effect of the product after administration at the proposed dosage regimen via the proposed route of administration and to specify its indications according to species, age, breed and sex, as well as its directions for use.
• Experimental data shall be confirmed by data obtained under normal field conditions.
• Dose determination studies: For each study, a summary of the study should be provided including including details on animals, test and control products, challenge, treatment, observation times and efficacy criteria. Results should be summarised. Tables of most relevant study results should be included.
• Dose confirmation studies: For each study, a summary of the study should be provided. Pivotal studies should be included. Results should be summarised. Tables of most relevant study results should be included.
• Field Trial: a short abstract should be provided, summarizing the study protocol and results. Tables of most relevant study results should be included.

• A tabular listing of all clinical studies and related information should be provided.
