Efficacy and safety of Ban-Lan-Gen granules in the treatment of seasonal influenza: study protocol for a randomized controlled trial.

ABSTRACT: Ban-Lan-Gen (BLG) is a traditional Chinese herbal medicine. It has been used for the prevention and treatment of virus-related respiratory diseases such as influenza virus infection. BLG contains some antiviral compounds, but few evidence-based clinical studies have been conducted to assess its efficacy against influenza. We assessed the effects of BLG (including efficacy and safety) on the treatment of seasonal influenza in an evidence-based clinical trial.We conducted a randomized, double-blinded, oseltamivir- and placebo-controlled, parallel-design clinical trial. A total of 177 subjects are going to be recruited after satisfying the criteria: (i) 18 to 65 years of age; (ii) illness onset within 36 h; (3) axillary temperature ?38.0°C; and (iv) positive influenza (type A/B) virus test. Subjects will be assigned randomly into three groups in equal proportions: oseltamivir treatment, BLG granule treatment, and placebo treatment. Each group receives 5-day treatment and is followed up 1, 3, 5, 7 and 21 days later. Symptoms and patient compliance are recorded, and virus/serum viral antibodies tested. We will use the primary outcome, secondary outcome, and safety indicators to evaluate the efficacy and safety of BLG granules in the treatment of seasonal influenza.We have described the first clinical trial for treatment using a single herb against influenza A and B viruses in China. We will hold a large-scale clinical trial to comprehensively evaluate the effectiveness and safety of BLG against influenza infection based on the results of this pilot study. And this clinical trial will serve as an example for the study of other traditional herbal medicines in evidence-based clinical trials.This study has been registered at ClinicalTrials.gov: NCT02232945 (3 September 2014).

Project description:INTRODUCTION:Chou-Ling-Dan (CLD) (Laggerapterodonta) granules are an ethnic herbal medicine from Yunnan province of China. CLD granules have been used for the treatment of inflammatory conditions and feverish diseases in China, including seasonal influenza, but few evidence-based medicine (EBM) clinical studies have been conducted to assess its efficacy and safety in the treatment of influenza. Here, we performed an EBM clinical trial combining Western Chinese medicine and traditional Chinese medicine (TCM) evaluation systems to evaluate the efficacy and safety of CLD granules in the treatment of seasonal influenza. METHODS AND ANALYSIS:The study is designed as a multicentre, randomised, double-blinded, double-simulation, oseltamivir-controlled and placebo-controlled, parallel-design clinical trial. Eligible subjects (n=318) will be allocated after satisfying the criteria (Western medicine). Subjects will be randomised to receive CLD granules, oseltamivir, or a placebo for 5 days of treatment and with follow-up after treatment to record symptoms and signs and to collect pharyngeal/throat swabs and serum samples for detecting the virus and antibodies. At the same time, the syndrome differentiation criteria of TCM, such as tongue body, furred tongue and type of pulse, will be recorded as determined by doctors of both Western and Chinese medicine. Participants will be instructed to comply with the protocol and to keep a daily record of symptoms. The primary and secondary outcomes and safety indicators will be used to evaluate the efficacy and safety of CLD granules in the treatment of seasonal influenza based on both Western Chinese medicine and TCM evaluation systems. ETHICS AND DISSEMINATION:The CLD granules clinical trial will be conducted in accordance with the Declaration of Helsinki and Good Clinical Practice and has been approved by the Ethics Committee of the First Affiliated Hospital of Guangzhou Medical University. All participants must provide written informed consent. The results obtained will be disseminated at international medical conferences and in peer-reviewed publications.

Project description:Background. Oxaliplatin-induced peripheral neuropathy (OIPN) is one of the most common side effects of oxaliplatin, which can cause reduction and cessation of oxaliplatin-based chemotherapy and significantly affect patients' quality of life. However, no drug has got recognition to prevent or treat OIPN. Yiqi-Wenjing-Fang (YWF) is a joint name of Chinese medicine prescriptions with similar effects of tonifying qi and warming meridians, represented by Huangqi Guizhi Wuwu decoction (HGWD) and Danggui Sini decoction (DSD), both from "Treatise on Cold Pathogenic and Miscellaneous Diseases." YWF granules, including HGWD granules and DSD granules, have been, respectively, demonstrated to be effective in preventing OIPN in previous small-sample observations. The purpose of this study is to enlarge the sample size for further evaluation of the preventive efficacy and safety of YWF granules on OIPN. Methods and Analysis. This study is a randomized, double-blind, placebo-controlled, and multicenter clinical trial. 360 postoperative patients with stage IIa-IIIc colorectal cancer will be randomly assigned into placebo-control group, intervention group I, and intervention group II, taking the mimetic granules of YWF as placebo, HGWD granules and DSD granules, respectively. All subjects will receive oxaliplatin-based chemotherapy regimen at the same time. EORTC QLQ-CIPN20 will be used to assess the degree of OIPN as the primary outcome measure. The grades of OIPN, quality of life, chemotherapeutic efficacy, and the number of completed chemotherapy cycles are selected as the secondary outcome measures. Discussion. Based on the condition of no recognized effective drugs in preventing OIPN, evidence-based medical study will be conducted for seeking a breakthrough in the field of Chinese herb medicine. This protocol could provide reliable and systemic research basis about the efficacy of YWF granules and the differentiation of two classical prescriptions of YWF on preventing OIPN objectively. Trial Registration. This study was registered at ClinicalTrials.gov on 26 December 2020 (ID: https://clinicaltrials.gov/ct2/show/NCT04690283).
