Abstract Background: COVID-19 is a respiratory disease caused by a novel coronavirus (SARS-CoV-2) and causes substantial morbidity and mortality. At the time this clinical trial was planned, there were no available vaccine or therapeutic agents with proven efficacy, but the severity of the condition prompted the use of several pharmacological and non-pharmacological interventions. It has long been hypothesized that the use of convalescent plasma (CP) from infected patients who have developed an effective immune response is likely to be an option for the treatment of patients with a variety of severe acute respiratory infections (SARI) of viral etiology. The aim of this study is to assess the efficacy and safety of convalescent plasma in adult patients with severe COVID-19 pneumonia. Methods/Design: The ConPlas-19 study is a multicenter, randomized, open-label controlled trial. The study has been planned to include 278 adult patients hospitalized with severe COVID-19 infection not requiring mechanical ventilation (invasive or non-invasive). Subjects are randomly assigned in a 1:1 ratio (139 per treatment arm), stratified by center, to receive intravenously administered CP (single infusion) plus SOC or SOC alone, and are to be followed for 30 days. The primary endpoint of the study is the proportion of patients that progress to categories 5, 6 or 7 (on the 7-point ordinal scale proposed by the WHO) at day 15. Interim analyses for efficacy and/or futility will be conducted once 20%, 40%, and 60% of the planned sample size are enrolled and complete D15 assessment.Discussion: This clinical trial is designed to evaluate the efficacy and safety of passive immunotherapy with convalescent plasma for the treatment of adult patients hospitalized with COVID-19. The results of this study are expected to contribute to establishing the potential place of CP in the therapeutics for a new viral disease.

Abstract Background: Currently, coronavirus disease-2019 (COVID-19) is continuously and rapidly circulating, resulting in serious and extensive impact on human health. Due to the absence of antiviral medicine for COVID-19 thus far, it is desperately need to develop the effective medicine. Traditional Chinese medicine (TCM) has been widely applied in the treatment of epidemic diseases in China, hoping to produce clinical efficacy and decrease the use of antibiotics and glucocorticoid. The aim of this study is to evaluate the efficacy and safety of Baidu Jieduan granule in curing COVID-19. Methods/design: This multicenter, open-label randomized controlled trial is conducted 300 cases with COVID-19. The patients will be randomly (1:1) divided into treatment group or control group. All cases will receive standard therapy at the same time. The experiment group will receive Baidu Jieduan granule treatment twice a day for 14 days. The outcomes are assessed at baseline and at 3, 5, 7, 14 days after treatment initiation. The primary outcome is the rate of symptom (fever, fatigue, and coughing) recovery. Adverse events (AEs) will be monitored throughout the trial.Discussion: The study will provide a high-quality clinical evidence to support the efficacy and safety of Baidu Jieduan granule in treatment of moderate COVID-19, and also enrich the theory and practice of TCM in treating COVID-19.

Background: Mycophenolate mofetil (MMF) is an immune suppressant that selectively inhibits activated lymphocytes. Its usefulness in treating psoriasis has not been systematically investigated. Objective: To evaluate efficacy and safety of MMF as a monotherapy for psoriasis. Methods: This is a two-center, prospective, open-label clinical trial. Results: Twenty-three patients with moderate to severe psoriasis [mean psoriasis area and severity index (PASI) of 21.7] were treated with MMF 2–3 g/day for 12 weeks. Eighteen patients completed the study. The PASI was reduced by 24% ( p < 0.001) at 6 weeks, and by 47% ( p < 0.001) at 12 weeks. At the end of the treatment phase, 77% of the patients had significant reduction of PASI while 22% did not respond. The treatment was well tolerated. Five patients experienced mild nausea. One patient each had periorbital edema and pruritus. One patient had transient leukopenia. Conclusion: In this noncontrolled trial, the majority of patients with moderate to severe psoriasis responded to mycophenolate mofetil monotherapy with few adverse events. A randomized, controlled trial should be considered to confirm the usefulness of MMF as a monotherapy for psoriasis.

Severe Influenza

Abstract Background: Influenza can fall into three categories according to severity: mild influenza, severe influenza, and critical influenza. Severe influenza can result in critical illness and sometimes death particularly in patients with comorbidities, advanced age, or pregnancy. Neuraminidase inhibitors (NAIs) are the only antiviral drugs in widespread use for influenza. However, the effectiveness of NAIs against severe influenza is uncertain. New effective drugs or regimens are therefore urgently needed. Qiangzhu-qinggan (QZQG) formula has been found to be effective against influenza virus infection during long-term application in China, which lacks support of evidence-based clinical trial till now. This study is designed to assess the efficacy and safety of QZQG formula as an adjuvant therapy in adult patients with severe influenza. Methods: This protocol is drawn up in accordance with the SPIRIT guidelines and CONSORT Extension for Chinese herbal medicine formulas. This is a randomized, placebo-controlled, double-blind, multicenter trial. 228 adults with severe influenza are randomly assigned in a 1:1 ratio to QZQG or placebo for 7 days and receive 1 day of screening, 7 days of intervention and 21 days of observation. The primary outcome is the proportion of clinical improvement, defined as the proportion of patients who met the criteria of 3 points or less in the seven-category ordinal scale or 2 points or less in National Early Warning Score 2 within 7 days after randomization. Discussion: This is the first randomized, controlled, parallel, double-blind clinical trial to evaluate the efficacy and safety of traditional Chinese herbal formula granules as an adjuvant therapy in adult patients with severe influenza. This study aims to redefine the value of traditional Chinese herbal medicines in the treatment of virus-related respiratory infectious diseases and serves as an example of evidence-based clinical trials of other Chinese herbal medicines.

Abstract Background: Coronary microvascular disease (CMVD) refers to cardiovascular diseases with normal coronary angiography but evidence of myocardial ischemia or microcirculation lesions, often presenting as angina pectoris attack. Coronary artery of microtubules dysfunction is one of the pathogenesis of coronary heart disease,but the occurrence and development and the current of CMVD intervention therapy remains to be further researched.Chinese traditional medicine (TCM)has advantages in the treatment of cardiovascular diseases, therefore, this article describes an ongoing randomized controlled clinical trial, based on the theory of TCM, for the purpose of evaluating the efficacy and safety of Guhong injection ,a Chinese patent medicine,compared with placebo in patients suffering from CMVD. Methods/design: This is a multicenter, randomized, parallel arm, open-label, double-blind, placebo-controlled clinical trial. A total of 260 eligible patients will be allocated and randomly assigned, in a ratio of 1:1, to either the experimental group or the control group. The treatment course is 10 consecutive days, with a 8-week follow-up. The primary outcome is the frequency of angina attacks, Secondary outcomes include myocardial metabolites, ecg changes, quantitative score of TCM syndromes, inflammatory response and endothelial function indicators. Discussion: This trial is strictly designed in accordance with principles and regulations issued by the China Food and Drug Administration (CFDA). The results will provide high quality evidence on the efficacy and safety of Guhong injection in the treatment of CMVD. Trial registration: Chinese Clinical Trials Registry, ChiCTR1900022902.
