Perspectives of international multi-center clinical trials on traditional Chinese herbal medicine

Abstract

With the introduction of various subjects, such as clinical epidemiology and evidence-based medicine, the qualities and levels of Traditional Chinese Herbal Medicine (TCHM) in China improved substantially, and the processes of internationalization of Traditional Chinese Medicine (TCM) are further accelerated. Since, a variety of drug products in China have been approved for marketing in other countries, and approximately 10 products have submitted the IND application to FDA of United States, of which various Chinese herbal preparations such as compound Danshen dripping pills, Xingling granules, and HMPL-004 have been approved to be investigated in phase III clinical trials. In general, multi-center studies of TCHM are increasing with years, but most of the studies are performed in some certain country, and the actual international multi-center clinical trials are very rare. Number of SCI literatures on multi-center clinical trials of TCHM that published in the recent decade also showed increasing tendency with years, despite the evident reduction in the past 2 years due to the influence of COVID-19 pandemic. Of the multi-center clinical trials of TCHM that performed by mainland China and other oversees regions, except for Taiwan, China, nearly 70% were focused on classic Chinese medicinal formulae and Chinese patent medicine, while the other 30% were on dietary supplements and plant extracts. Facing the future, the “human experience” has attracted close attentions from researchers throughout the world. Effectively utilizing the historic “human experience” is an important method to vitalize potential of original scientific and technological resources of TCHM. Performing multi-center clinical trials with high qualities is still an essential method for TCHM in accessing the mainstream medicine market. In addition, it is also required to further improve the evaluation techniques and methods that not only meet the international standards but also meet the characteristics of TCHM. Furthermore, we should also focus on the TCHM specific clinical values and scientific reports.

Understanding Proteinuria in Patients with Diabetic Kidney Disease and Progress of Drug Therapy from a New Perspective

“…Therefore, Shenshuaining [122], Fufang Xueshuantong [123], Shenyan Kangfu tablets [124,125], and Liuwei Dihuang decoction [126], which are also combined with Western medicine for the treatment of DKD and effective reduction of proteinuria, should be further confirmed by real-world research and more high-quality, large-scale, and multicenter RCT studies. Chinese patent medicine has broad development potential and an upward space for treating DKD proteinuria [127][128][129].…”

Nanoemulsion and nanoencapsulation of a hydroethanolic extract of Nettle (Urtica dioica) and Wormwood (Artemisia absinthium): comparison of antibacterial and anticancer activity

“…There is a long history of using plants to treat diseases, and many traditional medical therapies have their roots in the use of medicinal plants. Today, medicinal plants are attractive for many researchers due to their low side effects, variety of effective ingredients, strong anti-inflammatory and antioxidant activity, and their ability to prevent tumor growth ( Chaleshtori et al, 2015 ; Wu et al, 2023 ). In this regard, in recent decades, plants have become globally significant sources of new anticancer drugs and antibiotics ( Kaur et al, 2023 ; Shehabeldine et al, 2023 ).…”

Cultivable Endophyte Resources in Medicinal Plants and Effects on Hosts

“…All or part of medicinal plants are used in medicine and will also be used as raw materials for the pharmaceutical industry, which have a wide range of medicinal and economic uses [ 2 ]. Especially in the field of traditional medicine represented by traditional Chinese medicine and Indian folk medicine, medicinal plants, as the main source of natural drugs, provide very important health care services for the population of developing countries [ 3 , 4 , 5 ]. With the rapid development of modern medicine, many clinical drugs still come from natural products extracted from medicinal plants [ 2 ].…”
