[Reflections on supervision strategies of new Tibetan drug registration].

Tibetan medicine is an essential part of Chinese medicine and has unique theoretical experience and therapeutic advantages. According to the development principle of inheriting the essence, sticking to the truth, and keeping innovative, the supervision department should give clear and reasonable guidance considering the characteristics of Tibetan medicine, establish a standard system for quality control, clinical verification and evaluation, and accelerate the research and commercialization of new drugs. In view of the needs of drug supply-side reform and the current situation of Tibetan medicine and new pharmaceutical research, we ponder and provide suggestions on the confusion faced by the current supervision of Tibetan drug registration, hoping to contribute to the supervision strategy of Tibetan drug registration and the high-quality development of Tibetan medicine industry.

Hepatic Artery Injection of 131I-Metuximab Combined with Transcatheter Arterial Chemoembolization for Unresectable Hepatocellular Carcinoma: A Prospective Nonrandomized, Multicenter Clinical Trial.

This prospective nonrandomized, multicenter clinical trial was performed to investigate the efficacy and safety of 131I-labeled metuximab in adjuvant treatment of unresectable hepatocellular carcinoma. Methods: Patients were assigned to treatment with transcatheter arterial chemoembolization (TACE) combined with 131I-metuximab or TACE alone. The primary outcome was overall tumor recurrence. The secondary outcomes were safety and overall survival. Results: The median time to tumor recurrence was 6 mo in the TACE + 131I-metuximab group (n = 160) and 3 mo in the TACE group (n = 160) (hazard ratio, 0.55; 95% CI, 0.43-0.70; P < 0.001). The median overall survival was 28 mo in the TACE + 131I-metuximab group and 19 mo in the TACE group (hazard ratio, 0.62; 95% CI, 0.47-0.82; P = 0.001). Conclusion: TACE + 131I-metuximab showed a greater antirecurrence benefit, significantly improved the 5-y survival of patients with advanced hepatocellular carcinoma, and was well tolerated by patients.

Effects and safety of herbal medicines among community-dwelling residents during COVID-19 pandemic: A large prospective, randomized controlled trial (RCT).

BACKGROUND: Since the declaration of COVID-19 as a global pandemic by the World Health Organization, countries are struggling with a shortage of medical capacities. It would be essential if the risk for preventable comorbidities, such as the common cold, can be reduced or prevented, so that the scarce medical resources and facilities can be focused on COVID-19. PURPOSE: To evaluate the effects of two herbal medicines (Jinhaoartemisia antipyretic granules and Huoxiangzhengqi oral liquids) in reducing the risk of the common cold in community-dwelling residents in China during the COVID-19 outbreak. STUDY DESIGN: A prospective open-label, parallel-group, cluster-randomized controlled trial (RCT), was conducted in Chengdu, China. METHODS: A total of 22,065 participants from 11 communities were recruited during a period of one month. The trial started on 30 January and participants were followed up till 29 February 2020. Participants were randomly assigned to receive either a five-day herbal medicine therapy plus a reference manual or a reference manual only if they were allocated to the control group. The primary endpoint was the occurrence of patient-reported common cold symptoms. The secondary endpoint was the time in days from the receipt of herbal drugs/reference manual and the occurrence of the common cold symptoms. RESULTS: Use of herbal medicine reduced the risk of the common cold by 89.6% (95% CI, 52.9% to 97.7%) in all community-dwelling residents, and by 94.0% (95% CI, 52.1% to 99.2%) in residents aged between 16 and 59 years old. Sensitivity analyses showed similar results. CONCLUSION: This community-based RCT found that the use of a herbal medicine therapy (Jinhaoartemisia antipyretic granules and Huoxiangzhengqi oral liquids) could significantly reduce the risks of the common cold among community-dwelling residents, suggesting that herbal medicine may be a useful approach for public health intervention to minimize preventable morbidity during COVID-19 outbreak.

[Large- scale prospective clinical study on prophylactic intervention of COVID-19 in community population using Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules].

To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.

Safety profile of traditional Chinese herbal injection: An analysis of a spontaneous reporting system in China.

PURPOSE: Although a series of serious adverse events have continually raised concerns about the potential toxicity of traditional Chinese medicine injections (TCM injections), studies on this subject are still sparse. We conducted a descriptive analysis of a spontaneous reporting system in China to describe the safety profile of TCM injections. METHODS: The safety profile of TCM injections is described by descriptive analysis of 559 066 adverse reports collected from Guangdong Provincial Center for adverse drug reaction (ADR) Monitoring in China during 2003 to 2017. RESULTS: The percentage of new or serious ADRs of TCM injections is much higher than average percentage of China's spontaneous reporting system (SRS) as a whole (48.70% vs <25%). Compared with conventional injections, TCM injections have a slightly lower percentage of serious ADRs (6.02% vs 6.72%) and much higher percentage of unknown (new) ADRs (46.74% vs 24.13%). The gender and age distribution for TCM injections are similar to conventional injections. The reporting rates of ADRs increased with age. Anaphylactic shock and anaphylactoid reaction are high-risk ADRs for TCM injections and, anaphylactic shock is ranked number 1 in causing deaths (50.00%). CONCLUSIONS: There are some differences and similarities on the safety profile between TCM injections and conventional injections. TCM injections have higher risk of adverse effects than any other dosage forms of TCM medications and higher percentage of new or serious adverse effects than conventional injections. A lot of work need to be done to clarify the huge amount of potential unknown adverse effects related to TCM injections.

Tumor Hypervascularity and hand-foot-skin reaction predict better outcomes in combination treatment of TACE and Sorafenib for intermediate hepatocellular carcinoma.

BACKGROUND: To validate the robust predictive values of tumor vascularity and hand-foot-skin reaction (HFSR) in combination treatment of transarterial chemoembolization (TACE) and sorafenib for patients with intermediate hepatocellular carcinoma (HCC), and then select the potential candidates who would survive best from such treatment. METHODS: A total of 132 treatment-naive patients with intermediate HCC undergoing combination therapy of TACE and sorafenib were recruited between January 2010 and December 2014. The tumor vascularity was defined according to digital subtraction angiography (DSA) and HFSR was assessed by the national cancer institute common terminology criteria for adverse events (NCI-CTCAE). The Mann-Whitney U test was used to assess the correlation between vascularity and radiologic response; time to radiologic progression (TTP) and overall survival (OS) were evaluated using Kaplan-Meier techniques and compared by log-rank test; factors associated with them were evaluated using multivariate Cox regression analysis. RESULTS: During a median follow up of 17.3 months, it was revealed that hypervascularity and development of ≥2 grade of HFSR within 60 days after sorafenib initiation were favorable predictors for TTP (HR 0.378, p < 0.001; HR 0.627, p = 0.018) and OS (HR 0.499, p = 0.002; HR 0.555, p = 0.004). The median TTP and OS for patients with both were 12.2 and 29.1 months, which were better than patients with either of them (6.0 months, HR 1.74, p = 0.012; 16.5 months, HR 1.73, p = 0.021), as well as those with neither (2.9 months, HR 3.74, p < 0.001; 11.9 months, HR 3.17, p < 0.001). CONCLUSIONS: Tumor hypervascularity and development of ≥2 grade of HFSR within 60 days were favorable predictive factors for the combination treatment of TACE and sorafenib, with both of which the patients survived longest and might be the potential candidates.

Hand-foot-skin reaction of grade ≥ 2 within sixty days as the optimal clinical marker best help predict survival in sorafenib therapy for HCC.

Background & Aims Sorafenib-related adverse events have been reported as clinical surrogates for treatment response in hepatocellular carcinoma (HCC); however, no consensus has been reached regarding the definition of responders. We evaluated the predictive abilities of different definitions for sorafenib response based on treatment-emergent adverse events, aiming to identify the most discriminatory one as a clinical marker. Methods From January 2010 to December 2014, 435 consecutive HCC patients treated with sorafenib were enrolled. Considering the type, severity and timing of adverse events, twelve different categories of sorafenib response were defined. By comparing their discriminatory abilities for survival, an indicative criterion was defined, the prognostic value of which was evaluated by time-dependent multivariate analysis, validated in various subsets and confirmed by landmark analysis. Results Using concordance (C)-index analysis and time-dependent receiver operating characteristic curves, the development of a hand-foot-skin reaction ≥ grade 2 within 60 days of sorafenib initiation (2HFSR60) showed the highest discriminating value. Based on this criterion, 161 (37.0%) sorafenib responders achieved decreased risk of death by 47% (adjusted HR 0.53, 95%CI 0.43-0.67, P < 0.001) and likelihood of progression by 26% (adjusted HR 0.74, 95%CI 0.58-0.96, P = 0.020) compared with non-responders. Notably, 2HFSR60 remained an effective discriminator among most subgroups and had superior predictive ability to previous definitions, even according to the landmark analysis. Conclusions Our study demonstrated that 2HFSR60, with the best discriminatory ability compared to currently available definitions of sorafenib-related adverse events, could be the optimal clinical marker to identify sorafenib responders with decreased risk of death by half.

Traditional Chinese herbal injection: Current status and future perspectives.

Traditional Chinese herbal injection, frequently referred to as TCM injection, has evolved over 70 years as a treatment modality that parallels injections of pharmaceutical products. As the market reach has not been analyzed systematically in the past literature this article performed a descriptive analysis of various aspects of TCM injections based on the following data sources: (1) information retrieved from website of drug registration system of China, and (2) regulatory documents, annual reports and ADR Information Bulletins issued by drug regulatory authority. As of December 31, 2017, 134 generic names of TCM injections from 224 manufacturers were approved for sale. Only 5 of the 134 TCM injections are documented in the present version of Ch.P (2015). Most TCM injections are documented in drug standards other than Ch.P. The formulation, ingredients and routes of administration of TCM injections are more complex than conventional chemical injections. Ten TCM injections are covered by national lists of essential medicine and 58 are covered by China's basic insurance program (2017). ADR reports related to TCM injections accounts for >50% of all ADR reports related to TCMs and the percentages have been rising annually. Making traditional medicine injectable might be a promising way to develop traditional medicines. However, many practical challenges need to be overcome by further development before a brighter future for injectable traditional medicines can reasonably be expected.

mRECIST response combined with sorafenib-related adverse events is superior to either criterion alone in predicting survival in HCC patients treated with TACE plus sorafenib.

The mRECIST and dermatologic adverse events (AEs) can be used to assess the patient response to transarterial chemoembolization (TACE) and/or sorafenib for hepatocellular carcinoma (HCC). Here, we aimed to combine the two criteria to stratify the prognosis in patients with unresectable HCC receiving TACE plus sorafenib (TACE-S). In total, 176 consecutive HCC patients treated with TACE-S were enrolled. CT scans and laboratory tests were conducted pretreatment (at baseline, 5-7 days before the TACE-S) and post-treatment (at 1, 2 and 3 months). The radiological response was assessed according to mRECIST. Sorafenib-related AEs were recorded every 2 weeks after oral administration, and patients with dermatologic AEs of Grade 2 or more were defined as dermatologic responders. The earliest time at which mRECIST and dermatologic responses correlated with survival was 2 months after therapy. The mRECIST-dermatologic AE combination assessment stratified patients into three different prognoses; responders on both assessments exhibited the longest median overall survival (OS), followed by responders on one assessment and non-responders on both assessments (30.5, 17.4 and 8.3 months, respectively; p < 0.001). Achieving the highest C-index, the mRECIST-dermatologic AE combination showed better performance in predicting survival than either mRECIST or dermatologic AEs alone. Furthermore, the mRECIST-dermatologic AE combination remained a significant predictor of OS, even when the patients were stratified according to the BCLC stage, ECOG score or alpha-fetoprotein (AFP) value. This study showed that the combination of mRECIST response and dermatologic AEs is superior to either criterion used alone for predicting the survival of HCC patients treated with TACE-S.

[Evaluation of the effect of ilaprazole on intragastric pH in patients with duodenal ulcer].

OBJECTIVE: To evaluate the effect of ilaprazole enteric tablets on intragastric pH in duodenal ulcer patients. METHODS: A randomized, double blind, positive controlled clinical trial was carried out. A total of forty-two patients with duodenal ulcer were randomized into low dose ilaprazole group (5 mg/d), medium dose ilaprazole group (10 mg/d), high dose ilaprazole group (20 mg/d) and omeprazole group (20 mg/d). An ambulatory 24 hour intragastric pH study was performed at the fifth treatment day. Fraction time pH above 3, 4 or 5, median values of 24 hour diurnal pH and 12 hour nocturnal pH, the percentage of patients with total time pH above 3, 4 or 5 at least for 18 hours were evaluated. RESULTS: There were no significant differences of fraction time pH above 3 or 4, median values of 24 hour diurnal pH and 12 hour nocturnal pH and the percentage of patients with total time pH above 3, 4 or 5 at least for 18 hours among all the groups with different doses of ilaprazole and the omeprazole group. The fraction time pH above 5 in medium and high dose ilaprazole groups were (87.96 + or - 12.29)% and (89.86 + or - 15.18)% respectively, which was higher than that in low dose ilaprazole group [(67.17 + or - 30.16)%] and omeprazole group [(76.14 + or - 16.75)%], P < 0.05. CONCLUSION: Ilaprazole has a strong effect on intragastric acid control with a dose dependent trend.
