AIM: Describe the general situation of the First-In-Human trials of the drugs, and summarize the design and results of the First-In-Human trials. METHODS: We searched the literature of the First-In-Human trials in 2009-2020 on PubMed and screened out the literature that met the research purpose. The basic information of the literature was collected. Data analysis was conducted to summarize relevant outcomes. RESULTS: A total of 559 First-In-Human trials were included in this study. The types of drugs included small molecule drugs (52.42%, 293/559), macromolecule drugs (45.62%, 255/559), and a small amount of cells and viruses (1.97%, 11/559) and so on. Regarding the determination of the starting dose, whether it was in macromolecules (23.86%, 21/88) or small molecules (30.15%, 41/136), No Observed Adverse Effect Level (27.68%, 62/224) was mainly used as the main reference basis, followed by preclinical research (21.88%, 49/224) and Minimal Anticipated Biological Effect Level (8.48%, 19/224), etc. In the dose escalation test, 50.19%(135/269) of the studies used the traditional standard 3+3 dose escalation method, followed by the accelerated titration method (7.06%, 19/269), and the improved 3+3 method (6.69%, 18/269), etc. CONCLUSION: The design of First-In-Human clinical trials has certain regularity in the content and results of the research design. In the subsequent trials, it is important to scientifically design the First-In-Human trials, and promote the safe and effective development of the First-In-Human trials of the drugs.
