Effects of fortified eggs and time-restricted eating on cardiometabolic health: The prosperity trial.

Background: Given the increasing interest in dietary interventions to improve cardiovascular health, this trial assessed the impact of fortified eggs (FE) versus nonegg supplemented diet and time-restricted eating (TRE) versus usual care diet on cardiovascular biomarkers.

Methods: The study was a unblinded, 2-by-2 factorial design, which randomized patients, with either a prior cardiovascular event or 2 cardiovascular risk factors, to FE or a nonegg supplemented diet and TRE or usual care diet. Patients randomized to FE were instructed to consume at least 12 FE/week (with eggs provided); those on a nonegg supplemented diet restricted egg consumption to <2 eggs/week.

Comparison of Radial Access, Guided Femoral Access, and Non-Guided Femoral Access Among Women Undergoing Percutaneous Coronary Intervention.

Objectives: This study was conducted to determine the association between radial access, guided femoral access, and non-guided femoral access on postprocedural bleeding and vascular complications after percutaneous coronary intervention (PCI).

Background: Bleeding events and major vascular complications after PCI are associated with increased morbidity, mortality, and cost. While the radial approach has been shown to be superior to the femoral approach in reducing bleeding and vascular complications, whether the use of micropuncture, fluoroscopy, or ultrasound mitigates these differences is unknown.

A randomized, blinded, multicenter trial of a gentamicin vancomycin gel (DFA-02) in patients undergoing abdominal surgery.

Background: SI is a significant medical problem. DFA-02 is an investigational bioresorbable modified release gel consisting of both gentamicin (16.8 mg/mL) and vancomycin (18.

A registry-based randomized trial comparing radial and femoral approaches in women undergoing percutaneous coronary intervention: the SAFE-PCI for Women (Study of Access Site for Enhancement of PCI for Women) trial.

Objectives: This study sought to determine the effect of radial access on outcomes in women undergoing percutaneous coronary intervention (PCI) using a registry-based randomized trial.

Background: Women are at increased risk of bleeding and vascular complications after PCI. The role of radial access in women is unclear.

Losmapimod, a novel p38 mitogen-activated protein kinase inhibitor, in non-ST-segment elevation myocardial infarction: a randomised phase 2 trial.

Background: p38 MAPK inhibition has potential myocardial protective effects. We assessed losmapimod, a potent oral p38 MAPK inhibitor, in patients with non-ST-segment elevation myocardial infarction (NSTEMI) in a double-blind, randomised, placebo-controlled trial.

Methods: From October, 2009, to November, 2011, NSTEMI patients were assigned oral losmapimod (7·5 mg or 15·0 mg loading dose followed by 7·5 mg twice daily) or matching placebo in a 3:3:2 ratio.

Use of the REG1 anticoagulation system in patients with acute coronary syndromes undergoing percutaneous coronary intervention: results from the phase II RADAR-PCI study.

Aims: We sought to determine the feasibility of conducting percutaneous coronary intervention (PCI) in high-risk acute coronary syndrome (ACS) patients utilising the REG1 system consisting of pegnivacogin, an aptameric factor IXa inhibitor, and its controlling agent anivamersen.

Methods And Results: In RADAR, ACS patients were randomised to pegnivacogin 1 mg/kg with 25%, 50%, 75%, or 100% anivamersen reversal or unfractionated heparin. Of the 640 patients randomised, 388 (61%) underwent PCI.

Safety of very early sheath removal in patients treated with REG1 for acute coronary syndromes: insights from the RADAR trial.

Background: RADAR compared REG1 (25%, 50%, 75%, 100% reversal) with unfractionated heparin (UFH) in 640 acute coronary syndrome (ACS) patients (479 REG1 patients, 161 UFH patients) undergoing an invasive management strategy. We sought to determine whether the REG1 anticoagulation system allows for safer early arterial sheath removal following cardiac catheterization.

Methods: REG1 patients had arterial sheath removal immediately post catheterization.

Embedding a randomized clinical trial into an ongoing registry infrastructure: unique opportunities for efficiency in design of the Study of Access site For Enhancement of Percutaneous Coronary Intervention for Women (SAFE-PCI for Women).

Women are at higher risk than men for bleeding and vascular complications after percutaneous coronary intervention (PCI). Compared with femoral access, radial access reduces these complications but may be more challenging in women because of higher rates of radial artery spasm, tortuosity, and occlusion as well as lower rates of procedure success. Whether the safety advantages of radial versus femoral access in women undergoing PCI are outweighed by reduced effectiveness has not been studied.

A Phase 2, randomized, partially blinded, active-controlled study assessing the efficacy and safety of variable anticoagulation reversal using the REG1 system in patients with acute coronary syndromes: results of the RADAR trial.

Aims: We sought to determine the degree of anticoagulation reversal required to mitigate bleeding, and assess the feasibility of using pegnivacogin to prevent ischaemic events in acute coronary syndrome (ACS) patients managed with an early invasive approach. REG1 consists of pegnivacogin, an RNA aptamer selective factor IXa inhibitor, and its complementary controlling agent, anivamersen. REG1 has not been studied in invasively managed patients with ACS nor has an optimal level of reversal allowing safe sheath removal been defined.

Characteristics of clinical trials registered in ClinicalTrials.gov, 2007-2010.

Context: Recent reports highlight gaps between guidelines-based treatment recommendations and evidence from clinical trials that supports those recommendations. Strengthened reporting requirements for studies registered with ClinicalTrials.gov enable a comprehensive evaluation of the national trials portfolio.

The database for aggregate analysis of ClinicalTrials.gov (AACT) and subsequent regrouping by clinical specialty.

Background: The ClinicalTrials.gov registry provides information regarding characteristics of past, current, and planned clinical studies to patients, clinicians, and researchers; in addition, registry data are available for bulk download. However, issues related to data structure, nomenclature, and changes in data collection over time present challenges to the aggregate analysis and interpretation of these data in general and to the analysis of trials according to clinical specialty in particular.

First clinical application of an actively reversible direct factor IXa inhibitor as an anticoagulation strategy in patients undergoing percutaneous coronary intervention.

Background: The ideal anticoagulant should prevent ischemic complications without increasing the risk of bleeding. Controlled anticoagulation is possible with the REG1 system, an RNA aptamer pair comprising the direct factor IXa inhibitor RB006 and its active control agent RB007.

Methods And Results: This phase 2a study included a roll-in group (n=2) treated with REG1 plus glycoprotein IIb/IIIa inhibitors followed by 2 groups randomized 5:1 to REG1 or unfractionated heparin.

A phase II multicenter double-blind placebo-controlled study of ethyl pyruvate in high-risk patients undergoing cardiac surgery with cardiopulmonary bypass.

Objective: Ethyl pyruvate (EP) is an investigational drug that has been shown to protect animals in several models of critical illness including myocardial or mesenteric ischemia/reperfusion injury, sepsis, and hemorrhagic shock. The purpose of this study was to assess the safety of EP administration to patients undergoing higher-risk cardiac surgery and to obtain preliminary efficacy data for the prevention of single and multisystem organ dysfunction.

Design: Double-blind, randomized, placebo-controlled study.

Phase 1b randomized study of antidote-controlled modulation of factor IXa activity in patients with stable coronary artery disease.

Background: Whether selective factor IXa inhibition produces an appropriate anticoagulant effect when combined with platelet-directed therapy in patients with stable coronary artery disease is unknown. REG1 consists of RB006 (drug), an injectable RNA aptamer that specifically binds and inhibits factor IXa, and RB007 (antidote), the complementary oligonucleotide that neutralizes its anti-IXa activity.

Methods And Results: We evaluated the safety, tolerability, and pharmacodynamic profile of REG1 in a randomized, double-blind, placebo-controlled study, assigning 50 subjects with coronary artery disease taking aspirin and/or clopidogrel to 4 dose levels of RB006 (15, 30, 50, and 75 mg) and RB007 (30, 60, 100, and 150 mg).

First-in-human experience of an antidote-controlled anticoagulant using RNA aptamer technology: a phase 1a pharmacodynamic evaluation of a drug-antidote pair for the controlled regulation of factor IXa activity.

Background: Selectivity, titratability, rapidity of onset, and active reversibility are desirable pharmacological properties of anticoagulant therapy administered for acute indications and collectively represent an attractive platform to maximize patient safety. A novel anticoagulation system (REG1, Regado Biosciences), developed using a protein-binding oligonucleotide to factor IXa (drug, RB006) and its complementary oligonucleotide antidote (RB007), was evaluated in healthy volunteers. The primary objective was to determine the safety profile and to characterize the pharmacodynamic responses in this first-in-human study.
