Randomized Controlled Trial Multicenter Study
A phase II, sham-controlled, double-blinded study testing the safety and efficacy of the coronary sinus reducer in patients with refractory angina: study protocol for a randomized controlled trial.
A growing population of patients lives with severe coronary artery disease not amenable to coronary revascularization and with refractory angina despite optimal medical therapy. Percutaneous reduction of the coronary sinus is an emerging treatment for myocardial ischemia that increases coronary sinus pressure to promote a transcollateral redistribution of coronary artery in-flow from nonischemic to ischemic subendocardial territories. A first-in-man study has demonstrated that the percutaneous reduction of the coronary sinus can be performed safely in such patients. The COSIRA trial seeks to assess whether a percutaneous reduction of the coronary sinus can improve the symptoms of refractory angina in patients with limited revascularization options. ⋯ Based on previous observations, the COSIRA is expected to provide a significant positive result or an informative null result upon which rational development decisions can be based. Patient safety is a central concern and extensive monitoring should allow an appropriate investigation of the safety related to the coronary sinus Reducer.

Randomized Controlled Trial Multicenter Study Comparative Study
Oral flucloxacillin and phenoxymethylpenicillin versus flucloxacillin alone for the emergency department outpatient treatment of cellulitis: study protocol for a randomised controlled trial.
Oral flucloxacillin, either alone or in combination with phenoxymethylpenicillin, is a commonly prescribed antibiotic for the treatment of cellulitis, particularly in Ireland and the United Kingdom. This study aims to establish the non-inferiority of oral monotherapy (flucloxacillin alone) to dual therapy (flucloxacillin and phenoxymethylpenicillin) for the outpatient treatment of cellulitis in adults. ⋯ This trial aims to establish the non-inferiority of flucloxacillin monotherapy to dual therapy in the treatment of uncomplicated cellulitis among ED patients. In doing so, this trial will bridge a knowledge gap in this understudied and common condition and will be relevant to clinicians across several different disciplines.

Randomized Controlled Trial Multicenter Study Comparative Study
Steroids or pentoxifylline for alcoholic hepatitis (STOPAH): study protocol for a randomised controlled trial.
Alcoholic hepatitis is the most florid presentation of alcohol-related liver disease. In its severe form, defined by a Maddrey's discriminant function (DF) ≥32, the 28-day mortality rate is approximately 35%. A number of potential treatments have been subjected to clinical trials, of which two, corticosteroids and pentoxifylline, may have therapeutic benefit. The role of corticosteroids is controversial as trial results have been inconsistent, whereas the role of pentoxifylline requires confirmation as only one previous placebo-controlled trial has been published. ⋯ STOPAH aims to be a definitive study to resolve controversy around the existing treatments for alcoholic hepatitis. Eligibility criteria are based on clinical parameters rather than liver biopsy, which are aligned with standard clinical practice in most hospitals. The use of a factorial design will allow two treatments to be evaluated in parallel, with efficient use of patient numbers to achieve high statistical power.

Randomized Controlled Trial Multicenter Study Comparative Study
A phase 3 tRial comparing capecitabinE in combination with SorafenIb or pLacebo for treatment of locally advanced or metastatIc HER2-Negative breast CancEr (the RESILIENCE study): study protocol for a randomized controlled trial.
Sorafenib is an oral multikinase inhibitor with antiangiogenic/antiproliferative activity. A randomized phase 2b screening trial in human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer demonstrated a significant improvement in progression-free survival (PFS) when sorafenib was added to capecitabine versus placebo (median 6.4 versus 4.1 months; hazard ratio = 0.58; P = 0.001). Most drug-related adverse events were Grade 1/2 in severity with the exception of Grade 3 hand-foot skin reaction/syndrome (44% versus 14%, respectively). These results suggest a role for the combination of sorafenib and capecitabine in breast cancer and supported a phase 3 confirmatory trial. Here we describe RESILIENCE - a multinational, double-blind, randomized, placebo-controlled, phase 3 trial - assessing the addition of sorafenib to first- or second-line capecitabine in advanced HER2-negative breast cancer. ⋯ RESILIENCE will provide definitive PFS data for the combination of sorafenib and capecitabine in advanced HER2-negative breast cancer and better characterize the benefit-to-risk profile.

Randomized Controlled Trial Multicenter Study
Mobile phone text message intervention to reduce binge drinking among young adults: study protocol for a randomized controlled trial.
Heavy episodic (binge) drinking is common among young adults and can lead to injury and illness. Young adults who seek care in the Emergency Department (ED) may be disproportionately affected with binge drinking behavior, therefore provide an opportunity to reduce future risk through screening, brief intervention and referral to treatment (SBIRT). Mobile phone text messaging (SMS) is a common form of communication among young adults and has been shown to be effective at providing behavioral support to young adult drinkers after ED discharge. Efficacy of SMS programs to reduce binge drinking remains unknown. ⋯ This study will test the hypothesis that a mobile phone text-messaging program will result in immediate and durable reductions in binge drinking among at-risk young adults. By testing an intervention group to an assessment-only and control group, we will be able to separate the effect of assessment reactivity. By collecting pre-weekend drinking intentions and post-weekend consumption data in the SA+F group, we will be able to better understand mechanism of change.
