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.

Objective To explore the latest progress of oncology drug clinical trials in China under COVID-19, as well as to provide decision-making evidence for related stakeholders. Research progress of oncology drug trials and approved cancer drugs in China in 2020 were systematically summarized and compared with 2019. Methods Information Disclosure Platform for Drug Clinical Studies and China Food and Drug Administration Query System for Domestic and Imported Drug were searched for registered clinical trials and approved oncology drugs, respectively. The trial scope, stage, drug type, effect and mechanism of domestic and global pharmaceutical enterprises were compared between 2019 and 2020. Results A total of 722 cancer drug trials registered in China in 2020, with an annual growth rate of 52.3%, accounting for 28.3% of all registered trials. Among them, 603 (83.5%) trials were initiated by domestic pharmaceutical enterprises, and 105 (14.5%) were international multicenter trials, phase I trials accounted for 44.5%. For all those trials, there were 458 cancer drug varieties, with an annual growth rate of 36.7%, and 361 (85.8%) were developed by domestic enterprises. Most of the investigational products were therapeutic innovative drugs (77.1%), major in tumor treatment (92.8%). In terms of mechanism, targeted drugs were the most popular, accounting for 76.6%, and programmed cell death-1 (PD-1) and epithelial growth factor receptor (EGFR) were the most common targets. In addition, there were 19 anticancer drugs from 17 companies approved in China in 2019, with 10 drugs from domestic companies. Lung cancer and breast cancer are the most common indications for both registered trials and marketed drugs. No statistically significant differences were found between 2020 and 2019 in terms of the distribution of trial sponsor, scope and stage, as well as the distribution of drug type, effect and mechanism (P>0.05). Conclusions During the Covid-19 epidemic period, clinical trials of oncology drugs in China progress smoothly and maintain a high growth rate. Series of innovative products obtained by domestic enterprises in 2020 is the main driving force of development of oncology drug clinical trials in China. [ABSTRACT FROM AUTHOR]

Objective To deliver macro understanding of the latest research progress on clinical trials and approved products of cancer drugs in China in 2019. Methods The number of clinical trials and related investigational products by domestic and foreign enterprises in 2019 were acquired in the China Food and Drug Administration Registration and Information Disclosure Platform for Drug Clinical Studies, while listed drugs were obtained in the China Food and Drug Administration Query System for Domestic and Imported Drug. Characteristics on stage, scope, indication of those trials, classification and mechanism of involved products, as well as listed anticancer drugs were summarized and depicted. Results There were 474 cancer drug trials registered in China in 2019, accounting for 21.8% of the total, and 397 (83.8%) were initiated by domestic pharmaceutical enterprises. Overall, international multicenter trials accounted for 13.1%, and phase I trials accounted for 47.3%. Compared with global enterprises, the proportion of international multi-center trials initiated by domestic companies is lower (4.8% vs. 55.8%, P<0.001), and the proportion of phase I clinical trials and bioequivalence trials is higher (51.9% vs. 23.4%, 19.4% vs. 1.3%, P<0.001). An accumulative of 27 cancer types were involved for all the cancer drug trials, and lung cancer, solid tumor, and breast cancer were the most common cancer types, with 103, 95 and 49 trials, respectively. For the three cancer types unique to Chinese population, gastric, liver and esophageal cancer, the total number of initiated trials was 47. For all those trials, there were 335 cancer drug varieties, with 86.0% developed by domestic pharmaceutical enterprises, including 300 therapeutic drugs, 30 adjunctive drugs and 5 preventive drugs. In terms of mechanism, targeted drugs and immune drugs were the most popular, accounting for 74.6% and 20.3%, respectively. In addition, 17 anticancer drugs targeting on 11 cancer types were approved in China in 2019. Conclusions Clinical trials on cancer drugs in China have ushered a booming era, with large number of innovative agents represented by targeted drugs and immune drugs under clinical development or putting into clinical practice. Those local enterprises are playing more and more critical roles. Strengthening clinical research and development on Chinese unique cancer types is the key direction of future work.

Objective To quantify the medical expenditure per case of patients with hepatitis B virus-related diseases in Qidong, Jiangsu, China, and analyze its composition and related influencing factors. Methods Cluster sampling was used to select consecutive cases in The People′s Hospital of Qidong and Qidong Infectious Diseases Hospital. A total of 217 hospitalized patients of HBV related primary liver cancer, 234 hospitalized patients with HBV related B cirrhosis, and 136 hospitalized patients with chronic hepatitis B (CHB) were enrolled, and the total inpatient and outpatient costs (medical costs per case) from January 2010 to December 2012 and related clinical data were collected from the hospital records. Expert consultation was performed to investigate the costs per case of patients with acute hepatitis B, HBsAg asymptomatic carriers, and occult HBV infection. Costs in different years were converted based on the consumer price index for medical and health consumption in 2014. The independent samples t-test was used for comparison of continuous data between groups, an analysis of variance was used for comparison between multiple groups, and the SNK-q test was used for comparison within each group. Multiple linear regression analysis (stepwise regression) was used to investigate the influencing factors for medical costs per case. Results The medical costs per case of patients with HBV related primary liver cancer, patients with HBV related cirrhosis, and CHB patients from 2010 to 2012 were 30183 RMB, 22066 RMB, and 15703 RMB, respectively, and the inpatient costs were 29058 RMB, 21383 RMB, and 15394 RMB, respectively, which accounted for 96.3%, 96.9%, and 98.0% of the medical costs per case. Drug costs of these three groups accounted for 55.0%, 73.4%, and 78.2% of the medical costs per case, respectively. The number of times of hospitalization (F=89.1, 67.7, and 11.5, all P＜0.001), treatment regimen (F=21.8, t=-2.1, and t=-3.7, P＜0.001, P=0.039, and P＜0.001), and type of medical insurance (t=3.1, 2.6, and 2.7, P=0.002, 0.011, and 0.012) were influencing factors for medical costs per case, while clinical stage was an influencing factor for medical costs per case only in CHB patients (a multivariate analysis for patients mild, moderate, and severe CHB: β=1.238, F=5.9, P=0.021). The medical costs per case for patients with acute hepatitis B were 5950 RMB, and the annual medical costs for HBsAg asymptomatic carriers and patients with occult HBV infection ranged from 770 RMB to 1540 RMB. Conclusion The medical costs of HBV related is increasing as the illness progresses. Our results will provide baseline information for the following economic evaluation of vaccination or screening interrention. [ABSTRACT FROM AUTHOR]
