Ivy leaves extracts have been used successfully to treat acute cough, and data from well-controlled trials is accumulating. We present a meta-analysis of two double-blind, randomized, placebo-controlled trials. Patients with acute respiratory tract infection (ARTI) received ivy leaves dry extract EA 575 (n = 228) or placebo (n = 162) for 7 days, followed by a 7-day period without treatment. The main efficacy outcome was the Bronchitis Severity Score (BSS). Individual patient data meta-analyses were performed using mixed models for repeated measures, analysis of covariance and logistic ordinal regression. Significant BSS differences between EA 575 and placebo occurred already after 2 days and increased until treatment end, with BSS reductions of 8.6 ± 0.2 and 6.2 ± 0.2 (marginal means ± SEM; p < 0.001). The score reduction for placebo after 7 days was comparable to that for EA 575 after 4 days. In the EA 575 group, the proportion of cough-free patients was 18.1% at treatment end and 56.2% at end of follow-up, compared to 9.3% and 25.6% for placebo, respectively. Adverse event rates for EA 575 and placebo were comparable. EA 575 reduces effectively the intensity of acute cough associated with ARTIs and leads to a significant acceleration of recovery. No safety signals were observed., (© 2022. The Author(s).)

Background: The recommended first-line treatment for unspecific and degenerative back pain consists of movement exercises and patient education., Objective: Using a pragmatic, randomized controlled trial, we evaluated the effectiveness of a digital home exercise program on self-reported pain intensity compared with the standard of care for physiotherapy., Methods: Participant recruitment was based on newspaper advertisements and a consecutive on-site assessment for eligibility and enrollment. Participants with unspecific and degenerative back pain aged ≥18 years were randomly assigned in a 1:1 ratio to receive a 12-week stand-alone digital home exercise program or physiotherapy. The digital home exercise program included 4 exercises daily, while physiotherapy included 6 to 12 sessions, depending on the severity of symptoms. The primary outcome was pain, which was assessed using a verbal numerical rating scale. The clinical relevance of pain reduction was assessed using the following thresholds: improvement of at least 1.4 points on the verbal numerical rating scale and a pain reduction of at least 30%., Results: During the study period, 108 participants were assigned to the intervention group and 105 participants to the control group. The mean difference in pain scores between the 2 groups at 12 weeks was -2.44 (95% CI -2.92 to -1.95; P<.01) in favor of the intervention group. The group receiving the digital therapeutic achieved a clinically relevant reduction in pain over the course of the study (baseline vs 12 weeks), with a mean change of -3.35 (SD 2.05) score points or -53.1% (SD 29.5). By contrast, this change did not reach clinical relevance in the control group (mean -0.91, SD 1.5; -14.6%, SD 25.3). Retention rates of 89.9% in the intervention group and 97.3% in the control group were maintained throughout the study., Conclusions: The use of the app-based home exercise program led to a significant and clinically relevant reduction in pain intensity throughout the 12-week duration of the program. The intervention studied showed superior improvement in self-reported pain intensity when compared with the standard of care. Given the great demand for standard physiotherapy for unspecific and degenerative back pain, digital therapeutics are evolving into a suitable therapeutic option that can overcome the limitations of access and availability of conventional modes of health care delivery into this spectrum of indications. However, further independent evaluations are required to support the growing body of evidence on the effectiveness of digital therapeutics in real-world care settings., Trial Registration: German Clinical Trials Register DRKS00022781; https://tinyurl.com/hpdraa89., (©Hannes Weise, Benedikt Zenner, Bettina Schmiedchen, Leo Benning, Michael Bulitta, Daniel Schmitz, Kuno Weise.

Background: The favorable benefit-risk profile of topical nonsteroidal anti-inflammatory drugs (NSAIDs) makes them a preferred treatment for pain relief in soft tissue injuries., Purpose: To assess the efficacy and safety of a novel etofenamate 70-mg medicated plaster in patients with acute uncomplicated ankle sprain., Study Design: Randomized controlled trial; Level of evidence, 1., Methods: Patients with grade 1 or 2 ankle sprain of recent onset were randomized to etofenamate or placebo plasters (1:1) applied twice daily for 7 days. Clinical assessments, including ankle pain on movement (POM) in mm on a 100-mm visual analog scale (VAS), were made at predefined intervals during the treatment period., Results: In total, 156 male or female adult patients (mean age, 35.3 ± 11.8 years) were enrolled. The fall in VAS values for POM from baseline to 72 hours was markedly in favor of the etofenamate plaster, with respective reductions of 52.7% and 24.0% for active and placebo plasters (least squares mean treatment difference, 22.1 mm; P value for analysis of covariance < .0001). Similar clinically relevant differences between etofenamate and placebo were seen for POM at the 48-, 96-, and 168-hour visits ( P < .0001). These differences between etofenamate and placebo plasters were reflected in area under the curve for POM, pain at rest, and ankle swelling measured at various time points during the 7 days. Time taken to achieve a meaningful (30%) and optimal (50%) reduction of POM was significantly shorter in the etofenamate group. The responder rate (proportion of patients with at least 50% pain reduction at 72 hours) was 52.5% for the etofenamate plaster and 7.7% for the placebo. A significantly greater proportion of patients randomized to etofenamate rated their progress and/or the treatment as "good" or "very good." The medicated plasters adhered well over the 12-hour dosing period and were very well-tolerated., Conclusion: With respect to the investigated indication, uncomplicated ankle sprain, the etofenamate plaster has therapeutic efficacy that is similar to that for the best available topical NSAID formulations., Registration: 2016-000252-99 (EudraCT number)., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: This study was supported in full by Drossapharm AG.

Introduction: The results of a clinical trial published in 2016 showed the efficacy of ivy leaves dry extract EA 575 versus placebo in the treatment of patients suffering from acute cough. A clinical trial with a very similar design was conducted to not only show the reproducibility of former results but also to investigate an alternative dosing scheme., Methods: This randomised, placebo-controlled, multicentre, double-blind clinical trial was conducted to assess the efficacy and safety of a liquid containing EA 575 in the treatment of acute bronchitis. A total of 209 patients were treated with a liquid containing EA 575 as an active investigational medicinal product (verum) either two (7.5 mL) or three (5 mL) times a day or placebo in the respective dosing scheme for 1 week, with a total observational period of 2 weeks. The primary efficacy outcome was a change in Bronchitis Severity Score (BSS) of the pooled placebo and pooled verum groups between visits 1 and 5. Additional secondary parameters were assessed, including, for example, change in cough severity as assessed by a visual analogue scale (VAS) and the Verbal Category Descriptive (VCD) score., Results: Superiority of verum over placebo was during and at the end of treatment, as measured by BSS. No significant differences between the dosing schemes were observed. VCD scores and VAS measurements also showed the superiority of verum over placebo., Conclusion: The existing data on the clinical efficacy of EA 575 were confirmed. Furthermore, a new dosing scheme was shown to be noninferior to the currently used scheme while maintaining the safety and tolerability of the well-established cough liquid containing EA 575., Competing Interests: Conflict of interest: A.

Background: A/H5N1 influenza virus has significant pandemic potential, and vaccination is the main prophylactic measure. This phase 2, randomized, observer-blind, multicenter study evaluated the safety and immunogenicity of two MF59-adjuvanted, cell culture-derived H5N1 (aH5N1c) vaccine formulations in healthy pediatric subjects 6 months to 17 years old., Methods: Subjects (N = 662) received 2 aH5N1c doses 3 weeks apart, containing either 7.5 μg (full dose) or 3.75 μg (half dose) hemagglutinin antigen per dose. Local reactions and adverse events (AEs) were assessed by age. Antibody responses were measured by hemagglutination inhibition assay and assessed as geometric mean titers, geometric mean ratios (GMRs) and percentages of subjects achieving titers ≥1:40 and seroconversion (NCT01776554)., Results: No vaccine-related serious AEs occurred. Incidence of solicited local reactions and systemic AEs were similar across vaccine groups. Tenderness and irritability in <6-year olds, and injection site pain, myalgia and fatigue in 6-17-year olds were the most commonly reported reactions in both full- and half-dose recipients. Frequencies of AEs were lower after the second dose than the first dose in all vaccine and age groups. Three weeks after the administration of a second dose, both full- and half-dose formulations met the Center for Biologics Evaluation Research and Review (United States) and Committee for Medicinal Products for Human Use (EU) licensure criteria for titers ≥1:40 (full dose 96% subjects; half dose 86%), seroconversion (full dose 96% subjects; half dose 86%), and GMR (full dose GMR 262; half dose 84). Antibody responses were highest in 6-35-month olds., Conclusions: In pediatric subjects, both aH5N1c vaccine formulations were well tolerated and highly immunogenic, meeting both US and EU licensure criteria for pandemic influenza vaccines.

Background: This randomized study was designed to investigate the superiority of gemcitabine (gem) plus nimotuzumab (nimo), an anti-epidermal growth factor receptor monoclonal antibody, compared with gem plus placebo as first-line therapy in patients with advanced pancreatic cancer., Patients and Methods: Patients with previously untreated, unresectable, locally advanced or metastatic pancreatic cancer were randomly assigned to receive gem: 1000 mg/m2, 30-min i.v. once weekly (d1, 8, 15; q29) and nimo: fixed dose of 400 mg once weekly as a 30-min infusion, or gem plus placebo, until progression or unacceptable toxicity. The primary end point was overall survival (OS), secondary end points included time to progression, overall response rate, safety and quality of life., Results: A total of 192 patients were randomized, with 186 of them being assessable for efficacy and safety (average age 63.6 years). One-year OS/progression-free survival (PFS) was 34%/22% for gem plus nimo compared with 19%/10% for gem plus placebo (HR = 0.69; P = 0.03/HR = 0.68; P = 0.02). Median OS/PFS was 8.6/5.1 months for gem plus nimo versus 6.0/3.4 mo in the gem plus placebo group (HR = 0.69; P = 0.0341/HR = 0.68; P = 0.0163), with very few grade 3/4 toxicities. KRAS wildtype patients experienced a significantly better OS than those with KRAS mutations (11.6 versus 5.6 months, P = 0.03)., Conclusion: This randomized study showed that nimo in combination with gem is safe and well tolerated. The 1-year OS and PFS rates for the entire population were significantly improved. Especially, those patients with KRAS wildtype seem to benefit. The study was registered as protocol ID OSAG101-PCS07, NCT00561990 and EudraCT 2007-000338-38., (© The Author 2017.

This randomized, placebo-controlled, double-blind trial was conducted to assess the efficacy and safety of ivy leaves cough liquid in the treatment of acute cough. A total of 181 adult patients with acute cough were treated with either ivy leaves cough liquid containing EA 575® or with placebo three times a day for one week. The primary efficacy outcome was cough severity (CS) assessed by Visual Analogue Scale (VAS) over the whole treatment period (area-under-the-curve (AUC0-168 h) over 7 days (visit (V)1, V2, V3, V4, and V5). The secondary endpoints were defined as the CS assessed by VAS over the whole observation period (V1 - V6) and by Bronchitis Severity Score (BSS) and Verbal Category Descriptive (VCD) score. The evaluation of the VAS, BSS and VCD score revealed that subjects treated with ivy leaves cough liquid showed statistically significant and clinically relevant reductions in CS, severity of symptoms associated with cough and bronchitis compared to the placebo group. Furthermore, a remarkable early onset of efficacy was observed as significant reductions of cough severity were detected within 48 hours after the first drug intake. At all following visits and even 7 days after the end of treatment (V6) this significant treatment advantage was detected in comparison to placebo. All adverse events (AEs) in this clinical trial were non-serious, mild or of moderate severity and not drug-related. This clinical trial proved consistent superiority of the ivy leaves cough liquid treatment versus placebo and confirmed the EA 575® preparation to be a safe and efficacious option for the treatment of acute cough.

Introduction: To evaluate whether alkaline phosphatase (AP) treatment improves renal function in sepsis-induced acute kidney injury (AKI), a prospective, double-blind, randomized, placebo-controlled study in critically ill patients with severe sepsis or septic shock with evidence of AKI was performed., Methods: Thirty-six adult patients with severe sepsis or septic shock according to Systemic Inflammatory Response Syndrome criteria and renal injury defined according to the AKI Network criteria were included. Dialysis intervention was standardized according to Acute Dialysis Quality Initiative consensus. Intravenous infusion of alkaline phosphatase (bolus injection of 67.5 U/kg body weight followed by continuous infusion of 132.5 U/kg/24 h for 48 hours, or placebo) starting within 48 hours of AKI onset and followed up to 28 days post-treatment. The primary outcome variable was progress in renal function variables (endogenous creatinine clearance, requirement and duration of renal replacement therapy, RRT) after 28 days. The secondary outcome variables included changes in circulating inflammatory mediators, urinary excretion of biomarkers of tubular injury, and safety., Results: There was a significant (P=0.02) difference in favor of AP treatment relative to controls for the primary outcome variable. Individual renal parameters showed that endogenous creatinine clearance (baseline to Day 28) was significantly higher in the treated group relative to placebo (from 50±27 to 108±73 mL/minute (mean±SEM) for the AP group; and from 40±37 to 65±30 mL/minute for placebo; P=0.01). Reductions in RRT requirement and duration did not reach significance. The results in renal parameters were supported by significantly more pronounced reductions in the systemic markers C-reactive protein, Interleukin-6, LPS-binding protein and in the urinary excretion of Kidney Injury Molecule-1 and Interleukin-18 in AP-treated patients relative to placebo. The Drug Safety Monitoring Board did not raise any issues throughout the trial., Conclusions: The improvements in renal function suggest alkaline phosphatase is a promising new treatment for patients with severe sepsis or septic shock with AKI., Trial Registration: www.clinicaltrials.gov: NCT00511186.

Purpose: More than 80% of patients with breast cancer undergoing postsurgical radiotherapy (RT) will develop radiodermatitis and approximately 10% of these patients show grade 3 lesions. Side effects may reduce the patient's compliance and can be limiting factors to follow RT protocols. Therefore, there is a high need for more effective prophylactic treatments. In this study, a silymarin-based cream (Leviaderm(®)) was tested in comparison to our standard of care (SOC) at the involved site., Methods: A total of 101 patients were evaluated after breast-conserving surgery followed by RT with 50.4 Gy plus boost 9-16 Gy. Of these, 51 patients were treated with the silymarin-based cream. In addition, 50 patients were documented receiving a panthenol-containing cream interventionally, if local skin lesions occurred. The acute skin reactions were classified according to the RTOG and VAS (Visual Analogue Scale) scores., Results: The median time to toxicity was prolonged significantly with silymarin-based cream (45 vs. 29 days (SOC), p < 0.0001). Only 9.8% of patients using silymarin-based cream showed grade 2 toxicity in week 5 of RT in comparison to 52% with SOC. At the end of RT, 23.5% of patients in the silymarin-based study group developed no skin reactions vs. 2% with SOC, while grade 3 toxicity occurred only in 2% in the silymarin-based arm compared to 28% (SOC)., Conclusions: Silymarin-based cream Leviaderm(®) may be a promising and effective treatment for the prevention of acute skin lesions caused by RT of breast cancer patients. To confirm the results of this nonrandomized, observational trial, this component should be tested in larger multicenter studies in this setting.

Objective: To test the efficacy of calcium dobesilate (CaD) in chronic venous insufficiency (CVI)., Method: Double-blind, parallel groups, placebo-controlled, multicentre trial in adult patients with symptomatic CVI and pitting oedema. Wearing of compression stockings Class II was admitted. During treatment period of eight weeks, the patients received CaD 3 × 500 mg/day or placebo. The leg volume calculation was based on a truncated cone model., Results: A total of 256 patients was randomized to treatment (dobesilate: n = 132, placebo: n = 124); the demographic and anamnestic data at admission were comparable in the two therapeutic groups. The volume of the lower calf diminished in the dobesilate group at the end of the active treatment period by -64.72 ± 111.93 cm³ (mean ± SD), independent of the concomitant usage of compression stockings versus placebo +0.8 ± 152.98 cm³ (P = 0.0002). The symptoms of pain, discomfort, heavy legs, tired legs, tingling, itching and cramps, as well as the global assessments by investigators and patients, also improved significantly (P < 0.05) better in the dobesilate group at the end of the treatment. The observed adverse events correspond to the known profile., Conclusion: Dobesilate reduces leg oedema and improves the symptoms of objectively diagnosed CVI, independent of the concomitant usage of compression stockings.

Objective: The objective was to show the superiority of comfrey root extract ointment to placebo ointment in patients with acute upper or lower back pain., Design: The study was conducted as a double-blind, multicentre, randomised clinical trial with parallel group design over a period of 5 days (SD 1). The patients (n = 120, mean age 36.9 years) were treated with verum or placebo ointment three times a day, 4 g ointment per application. The trial included four visits., Main Outcome Measures: The primary efficacy variable was the area under the curve (AUC) of the visual analogue scale (VAS) on active standardised movement values at visits 1 to 4. The secondary efficacy variables were back pain at rest using assessment by the patient on VAS, pressure algometry (pain-time curve; AUC over 5 days), global assessment of efficacy by the patient and the investigator, consumption of analgesic medication and functional impairment measured using the Oswestry disability index., Results: There was a significant treatment difference between comfrey extract and placebo regarding the primary variable. In the course of the trial the pain intensity on active standardised movement decreased on average (median) approximately 95.2% in the verum group and 37.8% in the placebo group., Conclusions: The results of this clinical trial were clear-cut and consistent across all primary and secondary efficacy variables. Comfrey root extract showed a remarkably potent and clinically relevant effect in reducing acute back pain. For the first time a fast-acting effect of the ointment (1 h) was also witnessed.

Background: Increased activity of intestinal alkaline phosphatase (AP) occurs locally in patients with ulcerative colitis (UC), aimed at repairing inflammatory tissue damage. We evaluated the safety and preliminary efficacy of exogenous AP administered to patients with UC in an open-label, first-in-patient exploratory trial, conducted in the Internal Medicine and Gastroenterology hospital departments in the Czech Republic and Italy., Methods: Twenty-one patients were enrolled (13 females), age 23-54 years, with steroid- and/or immunosuppressant-refractory, moderate/severe UC (Mayo score 6-11). Oral AP enzyme 30,000 U was administered daily for 7 days, intraduodenally. Efficacy outcomes were changes in Mayo score at Day 21 posttreatment; changes in Modified Truelove-Witts Severity index (MTWSI) at Days 21, 63; C-reactive protein and stool calprotectin levels at Days 7, 21, 63. Safety evaluations were adverse events and laboratory abnormalities reported up to Day 63 posttreatment., Results: No clinically relevant adverse events causing withdrawal or considered serious, or laboratory abnormalities or antibody formation against AP were observed. Mayo scores were significantly decreased at Day 21, and MTWSI at Days 21 and 63. C-reactive protein and stool calprotectin levels were decreased at Days 21 and 63. Clinical response on the Mayo score after a single 7-day AP course was 48% at Day 21., Conclusions: In this uncontrolled trial, administration of exogenous AP enzyme daily over a 7-day course to patients with UC was associated with short-term improvement in disease activity scores, with clinical effects being observed within 21 days and associated with reductions in C-reactive protein and stool calprotectin. AP enzyme treatment was well tolerated and nonimmunogenic.

Purpose: To evaluate the clinical pharmacology of exogenous alkaline phosphatase (AP)., Methods: Randomized, double-blind, placebo-controlled sequential protocols of (1) ascending doses and infusion duration (volunteers) and (2) fixed dose and duration (patients) were conducted at clinical pharmacology and intensive care units. A total of 103 subjects (67 male volunteers and 36 patients with severe sepsis) were administered exogenous, 10-min IV infusions (three ascending doses) or 24-72 h continuous (132.5-200 U kg(-1) 24 h(-1)) IV infusion with/without preceding loading dose and experimental endotoxemia for evaluations of pharmacokinetics, pharmacodynamics, safety parameters, antigenicity, inflammatory markers, and outcomes., Results: Linearity and dose-proportionality were shown during 10-min infusions. The relatively short elimination half-life necessitated a loading dose to achieve stable enzyme levels. Pharmacokinetic parameters in volunteers and patients were similar. Innate immunity response was not significantly influenced by AP, while renal function significantly improved in sepsis patients., Conclusions: The pharmacokinetics of exogenous AP is linear, dose-proportional, exhibit a short half-life, and are not influenced by renal impairment or dialysis.

Objectives: A previously published study comparing the efficacy of comfrey extract to a commercial diclofenac (CAS 78213-16-8) preparation in the treatment of unilateral ankle sprains is critically re-evaluated. The study was designed to show non-inferiority of the comfrey extract. The data were re-evaluated for superiority according to CPMP guidelines. The study was an observer-blind, randomised, multi-centre clinical trial with two independent treatment groups "comfrey extract" and "diclofenac gel" (parallel group design) and included a total of 164 patients (82 in the comfrey group and 82 in the diclofenac group, intention-to-treat (ITT) analysis). Key variables were the area under the curve (AUC) from Visits 1 to 2 of the difference of the tenderness values contra-lateral minus injured side (primary variable), pain assessment (Visual Analogue Scale, VAS) at rest and on movement by patient, swelling (figure-of-eight method) and ankle movement (neutral zero method). On average (mean difference comfrey extract minus diclofenac), the AUC was +61.1 h x N/cm2 greater for patients treated with comfrey extract compared to diclofenac treated patients (95% confidence interval: 19.08; 103.09 h x N/cm2). The difference between the two treatment groups was statistically significant (analysis of variance with factors "study drug", "centre", and "drug x centre interaction"). Safety was excellent in both treatment groups. The re-evaluation of the data showed superiority of the plant based ointment over the diclofenac gel in the treatment of distortions. It is encouraging and impressive to realize that a natural product seems to be an effective and safe alternative to the standard topical treatment with diclofenac.

Context: Policosanol is a natural substance derived from sugar cane that is advertised for its lipid-lowering effects as a nonprescription drug. More than 80 placebo-controlled or comparative trials, performed mostly by a single research institute, suggest that policosanol at doses of 5 to 40 mg/d has lipoprotein-lowering effects comparable with statins., Objectives: To determine the lipoprotein-lowering effects of Cuban sugar cane-derived policosanol and to establish, if effective, dose-dependency up to 80 mg/d in patients with hypercholesterolemia or combined hyperlipidemia., Design, Setting, and Participants: A multicenter (lipid outpatient clinics and general practitioners in Germany), randomized, double-blind, placebo-controlled, parallel-group trial conducted from September 29, 2000, to May 10, 2001, of patients with hypercholesterolemia or combined hyperlipidemia having baseline low-density lipoprotein cholesterol (LDL-C) levels of at least 150 mg/dL (> or =3.88 mmol/L) and either no or 1 cardiovascular risk factor other than known coronary heart disease, or baseline LDL-C levels of between 150 and 189 mg/dL (3.88-4.89 mmol/L) and 2 or more risk factors., Interventions: Open-label 6-week placebo and diet run-in phase followed by a double-blind 12-week treatment phase after randomization to 5 groups: 10, 20, 40, or 80 mg/d of policosanol or placebo., Main Outcome Measure: The percentage change of LDL-C, with changes in other lipoproteins as secondary outcome measures., Results: A total of 143 patients were randomized to 5 equal groups and were analyzed on an intention-to-treat basis. In none of the 5 treatment groups did LDL-C levels decrease more than 10% from baseline. No statistically significant difference between policosanol and placebo was observed. A nonparametric test analyzing dose-dependency yielded nonsignificant results. In none of the secondary outcome measures, namely total cholesterol, high-density lipoprotein cholesterol (HDL-C), very low-density lipoprotein cholesterol, triglycerides, lipoprotein(a), and ratio of total or LDL-C to HDL-C, were there any significant effects of policosanol. Policosanol was tolerated well without serious adverse events., Conclusion: In patients with hypercholesterolemia or combined hyperlipidemia, the sugar cane-derived policosanol in usual and high doses does not demonstrate a reduction in lipid levels beyond placebo., Trial Registration: clinicaltrials.gov Identifier: NCT00288483.

In the treatment of minor blunt injuries several topical drugs are known to have anti-inflammatory and analgesic properties. They represent, however, two fundamentally different major pharmacological therapy approaches: the "chemical-synthetical" and the "phytotherapeutical" approach. The main objective of this trial (CODEC&#95;2004) was to compare the efficacy and tolerability of an ointment of Comfrey extract (Extr. Rad. Symphyti) with that of a Diclofenac gel in the treatment of acute unilateral ankle sprain (distortion). In a single-blind, controlled, randomized, parallel-group, multicenter and confirmatory clinical trial outpatients with acute unilateral ankle sprains (n=164, mean age 29.0 years, 47.6% female) received either a 6 cm long ointment layer of Kytta-Salbe f (Comfrey extract) (n=82) or of Diclofenac gel containing 1.16 g of diclofenac diethylamine salt (n=82) for 7 +/- 1 days, four times a day. Primary variable was the area-under-the-curve (AUC) of the pain reaction to pressure on the injured area measured by a calibrated caliper (tonometer). Secondary variables were the circumference of the joint (swelling; figure-of-eight method), the individual spontaneous pain sensation at rest and at movement according to a Visual Analogue Scale (VAS), the judgment of impaired movements of the injured joint by the method of "neutral-zero", consumption of rescue medication (paracetamol), as well as the global efficacy evaluation and the global assessment of tolerability (both by physician and patient, 4 ranks). In this study the primary variable was also to be validated prospectively. It was confirmatorily shown that Comfrey extract is non-inferior to diclofenac. The 95% confidence interval for the AUC (Comfrey extract minus Diclofenac gel) was 19.01-103.09h*N/cm2 and was completely above the margin of non-inferiority. Moreover, the results of the primary and secondary variables indicate that Comfrey extract may be superior to Diclofenac gel.

Objectives: To investigate the clinical efficacy and safety of a newly developed diclofenac patch in the topical treatment of blunt impact injuries., Methods: This was a randomised, placebo controlled, double blind, multicentre study in 120 patients with traumatic blunt soft tissue injury. Within 3 h of the injury participants of sport competitions and training camps were enrolled and treated twice daily with the diclofenac or a placebo patch over a period of 7 days. Patients were randomised (1:1) to two parallel groups. Tenderness produced by pressure was measured twice daily during the first 3 days after enrollment as well as at day 7. Tenderness was defined as the amount of pressure (measured by a calibrated caliper at the centre of the injury) that first produced a pain reaction as reported by the patient., Results: The primary efficacy variable was the area under the curve for tenderness over the first 3 days. The diclofenac patch was significantly more effective than placebo (p<0.0001). The treatment effect was 64.7 kp h/cm2 (95% confidence interval 48.7 to 80.9) between diclofenac and placebo patches. These results were supported by all secondary efficacy variables. The diclofenac patch produced rapid pain relief as reflected by the time to reach resolution of pain at the injured site which was significantly shorter compared to placebo (p<0.0001). The diclofenac patch was well tolerated. The most frequently observed adverse events were local cutaneous adverse reactions (pruritus, rash) of minor severity occurring with the same frequency as in the placebo group., Conclusions: A newly developed diclofenac patch is effective and safe for the treatment of blunt impact injuries.

Objectives: Primary objective of this meta-analysis was to produce a systematic and quantitative review of two independent clinical trials of 20 mg trospium chloride (TCI) twice daily (b.i.d.) in patients with detrusor overactivity [Alloussi et al. 1998, Cardozo et al. 2000]., Patients and Methods: In two placebo-controlled, double-blind, multi-center studies, the effect of TCl on detrusor function was evaluated using urodynamic measurements. All 517 patients were randomized to receive TCl or placebo for 3 weeks. Urodynamic variables were measured at the beginning and at the end of the treatment. Safety was evaluated on the basis of adverse events (AEs), vital signs and laboratory tests., Results: TCl produced significant improvements in 'maximum cystometric bladder capacity' (median treatment effect = 52 ml, 95% confidence interval 32-71 ml, p<0.0001) and 'urinary volume at first unstable contraction' (median treatment effect = 48 ml, 95% confidence interval 28 to 68 ml, p = 0.0001). The patients' assessment of efficacy also showed significantly greater clinical improvement in the TCl group than in the placebo group (p < 0.0001). The patients recorded a 'cure' or a 'marked improvement' more often in the TCl group than in the placebo group (47.9% and 19.7%, respectively). TCl was well tolerated, with similar frequencies of AEs reported in both groups (TCl: 35.7%, placebo group: 38.9%)., Conclusions: Trospium chloride (20 mg twice daily) is an effective and safe medication for the treatment of detrusor overactivity.

Objectives: To investigate the clinical efficacy and safety of escin-containing gels in the topical treatment of blunt impact injuries., Methods: Competitors in soccer, handball, or karate competitions were enrolled within two hours of sustaining a strain, sprain, or contusion and treated three times with the trial gel within a period of eight hours. Patients were randomised to three parallel groups consisting of two active treatment gels, containing escin (1% or 2%), 5% diethylammonium salicylate, and 5000 IU heparin, or placebo gel. Tenderness produced by pressure was measured at 0 (baseline), 1, 2, 3, 4, 6, and 24 hours after enrollment (within two hours of the injury). Tenderness was defined as the amount of pressure (measured by a calibrated caliper at the centre of the injury) that first produced a pain reaction as reported by the patient., Results: A total of 158 patients were enrolled; 156 were evaluated in the intention to treat analysis. The primary efficacy variable was the area under the curve for tenderness over a six hour period. The gel preparations containing 1% and 2% escin were significantly more effective (a priori ordered hypotheses testing controlling the multiple alpha = 5% significance level) than placebo (p(1) = 0.0001 and p(2) = 0.0002 respectively). The treatment effects were 5.7 kp h/cm(2) (95% confidence interval (CI) 2.9 to 8.5) and 5.9 kilopond (kp) h/cm(2) (95% CI 2.9 to 8.8) between 1% escin and placebo and between 2% escin and placebo respectively. These results were supported by secondary efficacy variables. The time to reach the baseline contralateral tenderness value (resolution of pain) at the injured site was shorter in the treatment groups than in the placebo group (p<0.0001). Both active gel preparations produced more rapid pain relief than the placebo gel. No relevant differences were detected between the two active gels. The safety and tolerability of the escin-containing gels were excellent., Conclusions: Escin/diethylammonium salicylate/heparin combination gel preparations are effective and safe for the treatment of blunt impact injuries.

The aim of this confirmative, monocentre, double-blind, controlled clinical trial was to investigate whether different escin combinations show differences in comparison to placebo with regard to pain reactions in the topical treatment of sports injuries. A total of 126 patients with blunt injuries of the extremities were randomly allocated to four parallel groups: Reparil-Gel N (n = 32), Reparil-Gel (n = 31), Reparil-Sportgel (n = 32) and a placebo gel (n = 31). All patients were evaluated for efficacy (intention to treat) and tolerability. A per-protocol analysis was also carried out, in which 12 of the 126 patients were excluded due to protocol violations. The intention-to-treat and per-protocol analyses produced similar results. The patients had suffered contusions while participating in soccer, hockey, karate, tae-kwon-do, handball, American football, rugby or tennis. The measured variable was the pressure required at the centre of the lesion to elicit the first pain reaction (tenderness reaction) at measuring time 0 (baseline) and then 1, 2, 3, 4, 6 and 24 h after the injury. The primary variable was the area under the curve (AUC) for tenderness over a six-hour period. The mean AUC differed significantly in the four groups (Kruskal-Wallis test p = 0.0001). Then six pairwise comparisons of two treatment groups each were carried out using the Mann-Whitney test. To control the multiple significance level of 5%, the adjusted p-values according to the Holm-Shaffer method were used in these tests. The three active gels were significantly superior to the placebo gel (Mann-Whitney test, p = 0.0004 in each case) in terms of the AUC. There were no significant differences between the active test substances in terms of the primary variable. The intensity of the pain was also measured on a visual analogue scale (VAS). The pain diminished more rapidly with the Reparil gels than with the placebo. The tolerability of all test substances was good. No adverse events were observed in any of the 126 patients. Escin combination gels are more effective than a placebo and are also well tolerated. Therefore, they can be recommended for the treatment of blunt injuries caused during sports and leisure activities.

Common colds are one of the most frequent acute illnesses with major economical impact. Echinaceae purpureae herba (Echinacin, EC31J0) has shown promising results in the relief of common cold symptoms and the time taken to improvement compared to placebo. This study was aimed to confirm these findings by performing a randomised, double-blind, placebo-controlled clinical trial. A total of 80 adult male or female patients with first signs of a cold were recruited. The number of days of illness with a complete picture of the common cold (defined by the modified Jackson score of at least 5 points and experience of rhinorrhea and/or a subjective sensation of having a cold) was the primary end-point. In the verum group the median time of illness was 6.0 days compared to 9.0 days in the placebo group, assigning zero time for patients without a complete picture (one-sided p = 0.0112). EC31J0 was well tolerated and clinically effective in alleviating symptoms more rapidly than placebo in patients with a common cold.

The objective of the present study was to investigate the effects of a locally applied aqueous mistletoe extract (AME) on the growth of urinary bladder carcinoma MB49 in an orthotopic murine model. On day 1, a total of 4 x 10(4) tumor cells was implanted into the bladder of female C57BL/6J mice. The animals were then randomly allocated to three groups of 13 mice each. From day 11 onwards, AME was given intravesically 3 days a week for 4 consecutive weeks at concentrations related to 30 or 300 ng bioactive mistletoe lectin (ML)/ml. The animals received a total volume of 0.1 ml. In the control group, 39% of the mice survived to the end of the scheduled study period in comparison to 69% and 85% in the groups treated with 30 or 300 ng ML/ml, respectively. At necropsy, 80% of the surviving control animals showed a visible solid bladder tumor, whereas only 56% and 18% had tumors in the treated groups. In both cases, the differences were statistically significant at the high concentration in comparison to controls (p < 0.05). A non-significant effect was observed regarding the formation of multiple metastases (40% in controls vs 33% and 18% in the treated groups). From the results, it was concluded that under the conditions described, AME shows antitumoral activity which is considered to be mainly due to the cytotoxic properties of mistletoe lectins, the main effective constituents of mistletoe extracts.

Objectives: To assess the efficacy and safety of trospium chloride (TCl, 20 mg twice daily) in the treatment of detrusor instability, compared with placebo., Patients and Methods: In all, 208 patients were allocated at random to either TCl or placebo in a double-blind clinical study; the patients were treated for 3 weeks. Urodynamic values were measured at the beginning and end of the treatment period. Adverse events were recorded on patient diary cards. A confirmatory adaptive procedure with one planned interim analysis was used to evaluate efficacy., Results: Trospium chloride produced significant improvements in maximum cystometric bladder capacity (median treatment effect 22.0 mL, mean 37.3 mL, one-sided P = 0. 0054) and urinary volume at first unstable contraction (median treatment effect 45.0 mL, mean 63.6 mL, one-sided P = 0.0015). The patients' assessment of efficacy showed significantly greater clinical improvement in the TCl group than in the placebo group (two-sided P = 0.0047). Furthermore, TCl was well tolerated, with similar frequencies of adverse events reported in both groups (68% in the TCl and 62% in the placebo group)., Conclusion: Trospium chloride (20 mg twice daily) is an effective and safe option for the treatment of detrusor instability.

Therapy of detrusor hyperactivity with anticholinergic agents often is followed by adverse drug reactions. Intravesical application may be an interesting alternative. A randomised, single-blind, placebo-controlled, mono-centre clinical trial was carried out in 84 patients with urgency or urge incontinence. Due to intravesical administration of oxybutynin (CAS 5633-20-5) (n = 21) and trospium chloride (CAS 10405-02-4) (n = 21), respectively, a significant increase in maximum bladder capacity and decrease of detrusor pressure accompanied by an increase of residual urine were found in comparison to placebo in urodynamical investigations. Improvement of uninhibited bladder contractions occurred leading to higher filling volume. Under verapamil (CAS 152-11-4) (n = 21) no marked changes in the efficacy variables were found compared with placebo. All patients completed the study and were assessed with regard to efficacy and safety. No adverse events or marked changes in the vital signs were reported. The immediate onset of effect and the lack of adverse drug reactions suggest that treatment with topical oxybutynin or trospium chloride is an effective alternative in patients with intolerable side effects when orally treated. In addition, intravesical administration may be indicated in patients with bladder spasms due to indwelling catheter or in order to increase bladder capacity before percutaneous cystostomy.

The therapeutic effects of IS-5-MN and s.r. nifedipine were investigated in this double-blind, randomized, group-comparative, multicenter study over 2 weeks, in 251 patients with stable reproducible exercise-induced angina. After 2 weeks' treatment with IS-5-MN 20 mg b.i.d. or t.i.d., 61% of the patients were responders who showed an increase in total exercise time (to moderately severe angina) of greater than or equal to 20% in comparison with placebo in the run-in phase. The corresponding responder rate after s.r. nifedipine 20 mg b.i.d. or 40 mg b.i.d. was 53%. Both IS-5-MN and s.r. nifedipine significantly increased the total exercise time, the time to angina onset and to greater than or equal to 1 mm ST-depression, and significantly reduced the rate pressure product and the ST-segment depression at peak exercise in comparison with placebo in the run-in phase. The improvement in quality of life as indicated by the reduction in anginal episodes and intake of short-acting nitrates was comparable with both drugs. The pattern and incidence of all AEs were as expected in the two active treatment groups. The daily treatment costs for a 20 mg b.i.d. dosing regimen for both drugs in the Federal Republic of Germany was 64% higher for s.r. nifedipine than with IS-5-MN.

Sulotroban, a sulphonamide derivative, causes an inhibition of platelet aggregation by blocking thromboxane A2 receptors. We tested the effects of Sulotroban (4 x 800 mg per day) on acute events during and recurrence rate after coronary angioplasty, and compared it with placebo in a double-blind randomized fashion. The follow-up protocol included regular compliance control by pill count, stress testing, and coronary angiography at 6 months. Restenosis was defined as a loss of 50% of the initial gain in luminal diameter. A total of 107 patients were randomized. There were no differences between the groups in terms of age, sex, artery distribution, or left ventricular function. Primary success per vessel was 86% for the Sulotroban group (50/58), and 88% for the placebo group (51/58). Complications occurred in nine patients (8%): five emergency bypass operations and three myocardial infarctions. There were no differences between the centers, or the study groups. The study protocol was completed for 57 patients. There was one death in the placebo group. Restenosis was found in 65% of patients in the Sulotroban group (19/29) and 61% of patients in the placebo group (17/28) (ns). If all patients were included on an intention to treat basis, regardless of primary success and compliance with the protocol, the recurrence rate was 57% in the Sulotroban group (20/35), compared with 56% in the Placebo group (20/36) (ns). This randomized, double-blind study failed to show that Sulotroban is superior to placebo in preventing acute problems during, or restenosis after, coronary angioplasty.
