摘要:
To understand the current status and characteristics of clinical trials for oral diseases in China, for the purpose of providing a reference for the research and development of oral diseases in China. Retrieving the information on clinical trials related to oral diseases registered on the"Platforms for drug clinical trial registration and information"of the National Medical Products Administration from the date of the database establishment to December 31, 2024. The number of clinical trials, type of drugs, trial phases, indication, trial scope, design types were statistically analyzed. As of December 31, 2024, a total of 578 drug clinical trials for oral disease were registered, accounting for 2.1% (578/27 905) of the clinical trials disclosed on the platform during the same period. Bioequivalence clinical trials accounted for the highest proportion [73.9% (427/578)], followed by Phase Ⅰ [9.0% (52/578)], Phase Ⅱ [8.0% (46/578)], and Phase Ⅲ [4.5% (26/578)]. The 578 clinical trials involved 149 types of trial drugs, mainly chemical drugs, among which 127 were developed by domestic pharmaceutical enterprises and 27 by international pharmaceutical enterprises (the five investigational drugs have undergone clinical trials by both domestic and international pharmaceutical companies). The project leader units of the 578 drug clinical trials were distributed in 27 provinces, autonomous regions, municipalities, and Hong Kong Special Administrative Region. Excluding 427 bioequivalence clinical trials, the project leader units of 151 new drug clinical trials showed a significant aggregation phenomenon, and only three specialized oral hospitals have served as project leader units for drug clinical trials. The number of drug clinical trials for oral disease in China has generally shown an increasing trend, but there are still problems such as small number of clinical trials, low proportion of investment in new drug development and international multicenter trials, concentra
