AbstractIt’s a challenge for detecting the therapeutic targets of a polypharmacological drug from variations in the responsed networks in the differentiated populations with complex diseases, as stable coronary heart disease. Here, in an adaptive, 31-center, randomized, double-blind trial involving 920 patients with moderate symptomatic stable angina treated by 14-day Danhong injection(DHI), a kind of polypharmacological drug with high quality control, or placebo (0.9% saline), with 76-day following-up, we firstly confirmed that DHI could increase the proportion of patients with clinically significant changes on angina-frequency assessed by Seattle Angina Questionnaire (ΔSAQ-AF ≥ 20) (12.78% at Day 30, 95% confidence interval [CI] 5.86–19.71%, P = 0.0003, 13.82% at Day 60, 95% CI 6.82–20.82%, P = 0.0001 and 8.95% at Day 90, 95% CI 2.06–15.85%, P = 0.01). We also found that there were no significant differences in new-onset major vascular events (P = 0.8502) and serious adverse events (P = 0.9105) between DHI and placebo. After performing the RNA sequencing in 62 selected patients, we developed a systemic modular approach to identify differentially expressed modules (DEMs) of DHI with the Zsummary value less than 0 compared with the control group, calculated by weighted gene co-expression network analysis (WGCNA), and sketched out the basic framework on a modular map with 25 functional modules targeted by DHI. Furthermore, the effective therapeutic module (ETM), defined as the highest correlation value with the phenotype alteration (ΔSAQ-AF, the change in SAQ-AF at Day 30 from baseline) calculated by WGCNA, was identified in the population with the best effect (ΔSAQ-AF ≥ 40), which is related to anticoagulation and regulation of cholesterol metabolism. We assessed the modular flexibility of this ETM using the global topological D value based on Euclidean distance, which is correlated with phenotype alteration (r2: 0.8204, P = 0.019) by linear regression. Our study identified the anti-angina therapeutic module in the effective population treated by the multi-target drug. Modular methods facilitate the discovery of network pharmacological mechanisms and the advancement of precision medicine. (ClinicalTrials.gov identifier: NCT01681316).

A prospective, double-blind clinical study was performed to evaluate the combination of dipyridamole(Persantin)225 mg/day and acetyl salicyclic acid (ASA) 1 g/day prophylaxis of post-operative venous thromboembolism in elective total hip replacement. Patients were stratified according to age, and randomly assigned to receive drug or placebo. All patients were followed with 125I-labelledfibrinogen scanning for one week post-operatively, or until fully mobile. Venography was performed in 67/129 patients; in 27 patients the venogram was obtained to confirm a positive fibrinogen scan, in 40 patients an elective venogram was obtained on the 7th post-operative day to evaluate the operated thigh (a blind area for scanning). Thrombosis (by scan or venogram) was found in 16/66(24%) in the control group, and in 21/63(33%) in the treated group. Overall incidence was 37/129 (29%). Correlation of scan with venography was 90%. There were no clinically significant pulmonary emboli in either group. We conclude that the combination of ASA and dipridamole as given in this study is not effective prophylaxis in elective total hip replacement.

Patient Related Outcome

Meniscal tears are the most common orthopaedic injuries, with chronic lesions comprising up to 56% of cases. In these situations, no benefit with surgical treatment is observed. Thus, the purpose of this study was to investigate the effectiveness and safety of percutaneous intrameniscal platelet rich plasma (PRP) application to complement repair of a chronic meniscal lesion. This single centre, prospective, randomized, double-blind, placebo-controlled study included 72 patients. All subjects underwent meniscal trephination with or without concomitant PRP injection. Meniscal non-union observed in magnetic resonance arthrography or arthroscopy were considered as failures. Patient related outcome measures (PROMs) were assessed. The failure rate was significantly higher in the control group than in the PRP augmented group (70% vs. 48%, P = 0.04). Kaplan-Meyer analysis for arthroscopy-free survival showed significant reduction in the number of performed arthroscopies in the PRP augmented group. A notably higher percentage of patients treated with PRP achieved minimal clinically significant difference in visual analogue scale (VAS) and Knee injury and Osteoarthritis Outcome Score (KOOS) symptom scores. Our trial indicates that percutaneous meniscal trephination augmented with PRP results in a significant improvement in the rate of chronic meniscal tear healing and this procedure decreases the necessity for arthroscopy in the future (8% vs. 28%, P = 0.032).

Abstract Background Lasmiditan (LTN) is a selective 5-HT1F receptor agonist for the acute treatment of migraine in adults. We present detailed safety findings from the placebo-controlled, double-blind Phase 3 study, of LTN treatment across 4 attacks (CENTURION). Methods Patients were randomized 1:1:1 to LTN 200 mg (LTN200), LTN100, or a control group that received placebo for 3 attacks and LTN50 for either the 3rd or 4th attack (1:1). Safety analyses were conducted for patients who took ≥1 dose of study drug and, in some cases, those who took all 4 doses. Results Overall, 1471 patients treated 4494 attacks. The incidences of treatment-emergent serious adverse events (SAEs) were - placebo, n=2 (0.4 %); LTN100, n=1 (0.2 %); LTN200, n=2 (0.4 %); no specific treatment-emergent SAE was reported in more than one patient. The most common treatment emergent adverse events (TEAEs) with lasmiditan were dizziness, paresthesia, fatigue, nausea, vertigo, and somnolence; the vast majority were mild or moderate in severity. The incidences of these TEAEs were highest during the first attack and decreased during subsequent attacks. For patients who experienced a common TEAE with the first attack, less than 45 % experienced the same event in subsequent attacks. Patients who did not experience an event in the 1st attack infrequently experienced the same event in subsequent attacks. The time of onset of the common TEAE ranged from ~40 min to 1 h (dependent upon TEAE) and, for individual TEAE, the onset was similar across attacks. Duration was dependent upon TEAE and attack. It was shortest for paresthesia (< 2 h for all attacks); it ranged from 1.8 to 5.5 h for other common TEAEs and was generally similar across attacks. Serotonin syndrome was reported for 2 patients post LTN dosing; there were no meaningful differences across treatment groups in suicidality; there was no evidence of an increase in motor vehicle accidents. Conclusion In this blinded, controlled, multiple-attack study, LTN was associated with generally mild or moderate CNS-related TEAEs of short duration. TEAEs tended to decrease in frequency across the 4 attacks. Trial registration NCT03670810

Danhong Injection

To systematically evaluate the efficacy and safety of Danhong injection (DH) in treating acute coronary syndrome (ACS), randomized controlled trials (RCTs) regarding ACS treated by DH were searched in Chinese and English electronic databases from inception until June 2013. Two reviewers independently retrieved RCTs and extracted information. The Cochrane risk of bias method was used to assess the quality of the included studies, and a meta-analysis was conducted with Review Manager 5.2 software. About 26 RCTs with 2660 participants were included. The methodological quality was usually not high, and only one study used a randomized, double-blinded method. The meta-analysis indicated that on the basis of conventional therapy with Western medicine (WM), DH was more effective in increasing the total effective rate [RR = 1.24, 95%CI (1.17, 1.32), p < 0.00001]. Additionally, DH can decrease inflammatory cytokines, including high sensitive C-reactive protein (Hs-CRP) and interleukin-6 (IL-6), lower plasma viscosity, plasma endothelin-1 (ET-1) and brain natriuretic peptide (BNP), reduce the generation of myeloperoxidase (MPO), and decrease the number of T-wave inversion. There were no adverse drug reactions (ADR) reported in the experimental group, while one case occurred in the control group. Based on the systematic review, DH combined with WM was effective in the treatment of ACS. However, the safety of DH in the treatment of ACS should be further carefully interpreted by more large-scale and double-blind RCTs.

Objective. This double-blind and randomized placebo-controlled trial evaluated the safety and efficacy of Danhong injection combined with Naoxintong capsule in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI). Methods. ACS patients scheduled to undergo PCI (n=130) were equally and randomly apportioned to either a treatment or control group. After PCI, the treatment group received Danhong injection combined with Naoxintong capsule for 12 weeks, while the control group was given placebo. Both groups were otherwise treated with conventional secondary prevention of coronary artery disease. The groups were primarily evaluated for clinical efficacy and cardiovascular events. Evaluative indicators of safety included adverse events, platelet count, and liver, renal, and blood coagulation functions. Result. No cardiovascular events or adverse reactions were observed in either group. The treatment group demonstrated better signs of clinical efficacy, including left ventricular ejection fraction, higher nitric oxide levels, and lower levels of endothelin-1 (ET-1) and von Willebrand factor (VWF). Conclusion. ACS patients treated with Danhong injection combined with Naoxintong capsule after PCI demonstrated better improvement with regard to markers associated with atherosclerosis and adverse cardiovascular events, without apparent adverse effects. Thus, Danhong injection combined with Naoxintong capsule was safe and effective for treating ACS patients after PCI.

Background and Aims: Although irritable bowel syndrome is one of the most common gastrointestinal disorders presented to gastroenterologists, therapeutic strategies are not yet well-established. Accordingly, we conducted a randomized, double-blind, placebo-controlled, clinical trial to evaluate the possible superiority of adding glutamine supplement to low fermentable oligo- di- monosaccharides and polyols (FODMAP) diet in patients with irritable bowel syndrome (IBS).Methods: Eligible adults were randomized to receive a low FODMAP diet either with glutamine (15 g/day) or a placebo for 6 weeks. The primary endpoint was a significant reduction in IBS-symptom severity score (IBS-SSS). Secondary endpoints were changes in IBS symptoms, stool frequency, consistency, and quality of life.Results: The study group enrolled 50 patients, among which 22 participants from each group completed the study protocol. The glutamine group had significant changes in total IBS-severity score, dissatisfaction of bowel habit and interference with community function (58% reduction; P &lt; 0.001, 57% reduction; P &lt; 0.001, 51% reduction; P = 0.043, respectively). Improvement in IBS-severity score of more than 45% was observed in 22 of 25 participants (88%) in the glutamine group, while it was only 15 of 25 participants (60%) in the control group (p = 0.015). No serious adverse events were observed.Conclusions: Our findings indicated the superiority of adding glutamine supplementation to a low FODMAP diet in amelioration of IBS symptoms while confirming the beneficial effects of a low FODMAP diet in IBS management.

Treatment of osteoarthritis (OA) patients with comorbidities can be challenging due to adverse events and non-sufficient efficacy of modern drugs. A safe and effective alternative could be the methods of traditional medicine and their combinations. The aim of this study was to evaluate efficacy and safety of combination of curcuma-based parapharmaceutical preparation and acupuncture in metabolic phenotype of OA (MPOA). The trial design was pilot open-label “before – after” study with the duration of 12 weeks. The patients with MPOA received parapharmaceutical preparation Epigenorm Antivir in a daily dose of 1000 mg and underwent 15-20 sessions of classical acupuncture. We enrolled twenty three women with metabolic syndrome (MS), clinical and radiographic signs of gonarthrosis, mean age 66.5 years, mean body mass index 34.5. At the end of treatment there was a decrease in pain levels according to visual analogue scale (VAS) (before 65 (12.7), after 24.6 (21.0), р=0.001), WOMAC pain scale (before 210.6 (102.2), after 103 (80.8), p = 0.014), KOOS (before 47.8 (12.1), after 66.7 (16.2), р = 0.001). The treatment resulted in statistically significant improvement of daily and social activities, role functioning, and quality of life. The results were clinically significant as evidenced by the moderate (Cohen d > 0.5) and large (Cohen d > 0.8) effect sizes of most outcome changes in accordance with the Cohen classification. The clinical improvement was accompanied by the decrease in MS components – LDL cholesterol (before 3.26 (0.26) mmol/l, after 2.43 (0.2) mmol/l, р = 0.001), triglycerides (before 2.02 (0.16) mmol/l, after 1.31 (0.1) mmol/l, р = 0.005). The treatment resulted in the reduction of systemic inflammation as evidenced by the decrease in the concentrations of TNFα (before 15.9 (1.2) pg/ml, after 12.4 (0.8), р = 0.002), histamine (before 1.6 (0.2) ng/ml, after 0.7 (0.2) pg/ml, р = 0.034), IL-18 (before 208.8 (32.6 ) pg/ml, after 160.0 (26.0) pg/ml, р = 0.002) and CRP (before 6.05 (1.3) mg/l, after 3.2 (0.7) mg/l, р = 0.022). At the same time there was an increase of concentration of IL-10 (before 1.5 (0.7) pg/ml, after 3.8 (1.2), р = 0,006) and adiponectin (before 34.0 (5.6) pg/ml, after 40.0 (6.9), р = 0.034). The treatment was well tolerated, no serious adverse events were registered. The pleiotropic actions of combination treatment occured probably due to synergistic effects of herbal therapies and acupunctures. The results provide a rationale for larger scale, randomized controlled double-blind clinical trials.

ABSTRACTST-246 is being evaluated as a treatment for pathogenic orthopoxvirus infections in humans. To this end, a phase 2, double-blind, randomized, placebo-controlled, multicenter trial was conducted to assess the safety, tolerability, and pharmacokinetics (PK) of ST-246 when administered as a single daily oral dose (400 mg or 600 mg) for 14 days in fed adult volunteers. ST-246 was safe and well tolerated, with no deaths or serious adverse events reported during the study. There was a low incidence of treatment-emergent adverse events (TEAEs), the most common of which were mild nausea and headache. There were no clinically significant results from laboratory assessments, vital sign measurements, physical examinations, or electrocardiograms. The PK and dose proportionality of ST-246 were determined. The PK analysis showed that steady state was achieved by day 5 for the ST-246 400-mg treatment group and by day 6 for the 600-mg group. The dose proportionality analysis showed that the 400- and 600-mg ratio of dose-normalized peak drug concentration in plasma (Cmax) and relative exposure for each dosing interval (AUCτ) ranged from 80% to 85%. However, the 90% confidence intervals did not include 1.0, so dose proportionality could not be concluded. Overall, ST-246 was shown to be safe, and the PK was predictable. These results support further testing of ST-246 in a multicenter pivotal clinical safety study for licensure application.

We studied the effect of experimenter expectations and different instructions in a balanced placebo design. 157 subjects were randomized into a 2 × 4 factorial design. Two experimenters were led to expect placebos either to produce physiological effects or not (pro- vs. antiplacebo). All subjects except a control group received a caffeine placebo. They were either made to expect coffee, no coffee, or were in a double-blind condition. Dependent measures were blood pressure, heart rate, well-being, and a cognitive task. There was one main effect on the instruction factor (p = 0.03) with the group “told no caffeine” reporting significantly better well-being. There was one main effect on the experimenter factor with subjects instructed by experimenter “proplacebo” having higher systolic blood pressure (p = 0.008). There was one interaction with subjects instructed by experimenter “proplacebo” to receive coffee doing worse in the cognitive task than the rest. Subjects instructed by experimenter “antiplacebo” were significantly less likely to believe the experimental instruction, and that mostly if they had been instructed to receive coffee. Contrary to the literature we could not show an effect of instruction, but there was an effect of experimenters. It is likely, however, that these experimenter effects were not due to experimental manipulations, but to the difference in personalities.

SummaryThe pharmacokinetics and tolerability of factor XIII (FXIII) from plasma were compared with those of FXIII from placenta in a randomised, double-blind, crossover study involving 13 patients with congenital FXIII deficiency. Both FXIII activity and FXIII antigen were monitored. No difference was seen in the mean half-lives of the two preparations (9.3 days and 9.1 days for plasma and placenta FXIII activity, respectively). Response was similar for both preparations, but was slightly greater for FXIII from plasma.Similar results were found for recovery (65% vs 60%). The area under the data completed by extrapolation was significantly higher for FXIII from plasma. No differences between preparations in terms of efficacy or tolerability were observed. It can be concluded that treatment with FXIII concentrate from plasma is as efficient as with FXIII concentrate from placenta in terms of recovery and half-life. Both preparations were equivalent in terms of safety during the observation period. With the administration of monthly injections of approximately 30 U/kg serious bleeding events were prevented and no other serious adverse events occurred.
