ABSTRACT
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.
ABSTRACT
AIM: In order to bridge the gap between pharmacogenomic research and its clinical application, we propose the concept of genetic electronic identity, named "GeneFace", and developed an electronic information system which integrated "drug-gene" interactions and recommendations for personalized medicine. METHODS: Based on the self-developed Precision Medicine knowledgebase, which concludes drug directions, guidelines or important literatures with high level of evidence, we developed GeneFace with Java-based open-resource application framework Spring Boot, further developed a mobile App with cross-platform framework Uni-APP. RESULTS: The App includes six modules: genetic testing appointment, genetic knowledge introduction, individualized medication advice, medication records, Geneface interpretation, and Precision Medicine knowledgebase. By detecting the genotype of more than 300 gene loci upon first use, users import the results to form a personal "drug-gene identity card". Then scan or enter the drug name in "GeneFace", the App would automatically give corresponding medication recommendations, including: risks for possible adverse drug reactions, risks for reducing the efficacy or even ineffectiveness, and possibility for dose adjustment, etc., which increase the safety of clinical drug use. People can obtain pharmacogenomics knowledge and basic drug information in the "GeneFace" app. CONCLUSION: Development as a digital therapeutic product, the expanded application of GeneFace can rapidly promote clinical applications of basic pharmacogenomics research and significantly improve drug use safety, which creating a new model for accelerating the clinical application of personalized medicine.
ABSTRACT
AIM: To study the pharmacokinetic characteristics of single-dose oral moxifloxacin hydrochloride tablets under fasting and fed conditions, and use moxifloxacin hydrochloride tablets produced by Bayer Pharma AG as a reference to compare the pharmacokinetic parameters of the two preparations, and evaluate the human bioequivalence of the two preparations. METHODS: A single-center, randomized, open, two-period, and self-crossover design was adopted to conduct a fasting and fed bioequivalence study of 23 healthy subjects each. The 0.4 g dose preparations were taken orally per cycle on fasting or fed administration. The plasma concentrations of moxifloxacin at different times after administration were determined by HPLC-MS/MS. The main pharmacokinetic parameters were calculated, and the bioavailability of the test preparation relative to the reference preparation was evaluated. RESULTS: After subjects in the fasting group took the test preparation T and the reference preparation R, the main pharmacokinetic parameters of moxifloxacin hydrochloride were: C
