A Bridge from Preclinical to Clinical Development: Insights from Official FDA, EMA, and PMDA Guidelines and Approval Cases
In pharmaceutical development, it is crucial to connect data obtained in non-clinical studies to clinical trials and ultimately to approval. The FDA, EMA, and PMDA, through ICH guidelines and their own directives, respectively, provide concepts regarding non-clinical safety, First-in-Human (FIH), Good Clinical Practice (GCP), trial design, and dose optimization. This page introduces official guidelines that are highly valuable for practical reference, as well as case studies of approvals that are useful for deepening understanding.
A core document outlining when and to what extent non-clinical safety studies should be conducted and how data can be bridged to clinical trials and regulatory submissions.

In drug discovery, the quality and efficiency of non-clinical studies have a direct impact on clinical success rates, development costs, and overall length of time required in R&D.
In recent years, there has been more demand for clinically relevant data, globally accepted reliability, and accurate early-stage screening.
Thus, it is more important than ever to select the right CRO (Contract Research Organization) for strategic approach.
In this article, we highlight three CROs with proven technical capabilities, expertise, and long standing track records. These are our TOP 3 choices based on their capabilities and the specific target goals of the researchers for their non-clinical studies.
