It was said that Evaluators / EC may object to fund Phase 3/4 trials due to high costs. What if the proposals apply for partial costs, for example only certain sites?

Funding of Phase 3 or Phase 4 Trials depends on the topic. Some topics might even require later phases of trials as well. Generally, it is possible to claim partial costs. Just make sure to explain how you will cover the remaining costs that won’t be requested from the EC, so it will be clear to the reviewers that you will be able to conduct the CT properly. If you will apply only for partial costs of the study in the scope of the EU project, e.g. for certain study sites but will cover other sites by yourself, you will have to convince the reviewers that data of those sites not included in your project will still be obtained to ensure the feasibility of your project.
