ABSTRACT

Objective: Systematically summarize the research progress of clinical trials of gastric cancer oncology drugs and the overview of marketed drugs in China from 2012 to 2021, providing data and decision-making evidence for relevant departments. Methods: Based on the registration database of the drug clinical trial registration and information disclosure platform of Food and Drug Administration of China and the data query system of domestic and imported drugs, the information on gastric cancer drug clinical trials, investigational drugs and marketed drugs from January 1, 2012 to December 31, 2021 was analyzed, and the differences between Chinese and foreign enterprises in terms of trial scope, trial phase, treatment lines and drug type, effect and mechanism studies were compared. Results: A total of 114 drug clinical trials related to gastric tumor were registered in China from 2012 to 2021, accounting for 3.7% (114/3 041) of all anticancer drug clinical trials in the same period, the registration number showed a significant growth rate after 2016 and reached its peak with 32 trials in 2020. Among them, 85 (74.6%, 85/114) trials were initiated by Chinese pharmaceutical enterprise. Compared with foreign pharmaceutical enterprise, Chinese pharmaceutical enterprise had higher rates of phase I trials (35.3% vs 6.9%, P=0.001), but the rate of international multicenter trials (11.9% vs 67.9%, P<0.001) was relatively low. There were 76 different drugs involved in relevant clinical trials, of which 65 (85.5%) were targeted drugs. For targeted drugs, HER2 is the most common one (14 types), followed by PD-1 and multi-target VEGER. In the past ten years, 3 of 4 marketed drugs for gastric cancer treatment were domestic and included in the national medical insurance directory. Conclusions: From 2012 to 2021, China has made some progress in drug research and development for gastric carcinoma. However, compared with the serious disease burden, it is still insufficient. Targeted strengthening of research and development of investment in many aspects of gastric cancer drugs, such as new target discovery, matured target excavating, combination drug development and early line therapy promotion, is the key work in the future, especially for domestic companies.

ABSTRACT

Ephedra herb is a traditional Chinese medicine with a long history. Conventionally, it was used as a folk phytomedicine in many ancient medical books and traditional prescriptions. Up to date, a variety of specific ingredients have been found in Ephedra herb, mainly including alkaloids, flavonoids, tannins, polysaccharides, organic acids, volatile oils, and many other active compounds. These components from Ephedra herb account for its use as the accurate treatment of cold, cough, cardiovascular and immune system disease, cancer, microbial infection, and other diseases. Moreover, with the fast development of novel chemistry and medicine technology, new chemical constituents and pharmacological effects of Ephedra herb are increasingly identified, demonstrating their great potential for various diseases treatment. Therefore, further detailed understanding and investigation of this ancient herb will offer new opportunities to develop novel therapeutics. This study systematically reviews its progress of phytochemistry, traditional and modern pharmacology based on research data that have been reported, aiming at providing useful insight for commercial exploitation, further study and precision medication of Ephedra herb in future.
