The McCAVE Trial: Vanucizumab plus mFOLFOX‐6 Versus Bevacizumab plus mFOLFOX‐6 in Patients with Previously Untreated Metastatic Colorectal Carcinoma …

2019

Abstract Background Bevacizumab, a VEGF‐A inhibitor, in combination with chemotherapy, has proven to increase progression‐free survival (PFS) and overall survival in multiple lines of therapy of metastatic colorectal cancer (mCRC). The angiogenic factor angiopoetin‐2 (Ang‐2) is associated with poor prognosis in many cancers, including mCRC. Preclinical models demonstrate improved activity when inhibiting both VEGF‐A and Ang‐2, suggesting that the dual VEGF‐A and Ang‐2 blocker vanucizumab (RO5520985 or RG‐7221) may improve clinical outcomes. This phase II trial evaluated the efficacy of vanucizumab plus modified (m)FOLFOX‐6 (folinic acid (leucovorin), fluorouracil (5‐FU) and oxaliplatin) ver…

2022

Contains fulltext : 252214.pdf (Publisher’s version ) (Open Access) BACKGROUND: Geoeconomic variations in epidemiology, the practice of ventilation, and outcome in invasively ventilated intensive care unit (ICU) patients without acute respiratory distress syndrome (ARDS) remain unexplored. In this analysis we aim to address these gaps using individual patient data of four large observational studies. METHODS: In this pooled analysis we harmonised individual patient data from the ERICC, LUNG SAFE, PRoVENT, and PRoVENT-iMiC prospective observational studies, which were conducted from June, 2011, to December, 2018, in 534 ICUs in 54 countries. We used the 2016 World Bank classification to defi…

Geo-economic variations in epidemiology, patterns of care, and outcomes in patients with acute respiratory distress syndrome: insights from the LUNG …

2017

Background Little information is available about the geo-economic variations in demographics, management, and outcomes of patients with acute respiratory distress syndrome (ARDS). We aimed to characterise the effect of these geo-economic variations in patients enrolled in the Large Observational Study to Understand the Global Impact of Severe Acute Respiratory Failure (LUNG SAFE). Methods LUNG SAFE was done during 4 consecutive weeks in winter, 2014, in a convenience sample of 459 intensive-care units in 50 countries across six continents. Inclusion criteria were admission to a participating intensive-care unit (including transfers) within the enrolment window and receipt of invasive or non…

Final results of the McCAVE trial: A double-blind, randomized phase 2 study of vanucizumab (VAN) plus FOLFOX vs. bevacizumab (BEV) plus FOLFOX in pat…

2017

3539 Background: VEGF-A and ANG-2 have complementary roles in regulation of tumor angiogenesis. Targeting VEGF-A with BEV in combination chemotherapy (CT) in mCRC has proven to increase PFS and OS. ANG-2 is overexpressed and associated with poor outcome of mCRC pts receiving BEVcontaining treatment. Hence, dual blockade of VEGF-A and ANG-2 by the bispecific mAb VAN with standard CT may improve clinical activity in mCRC. Methods: All pts received mFOLFOX-6 and were randomized 1:1 to also receive intravenous VAN 2000 mg every other week (Q2W) (Arm A) or BEV 5 mg/kg Q2W (Arm B). The primary end point was investigator assessed progression-free survival (PFS). Key eligibility criteria included …

Hyperoxemia and excess oxygen use in early acute respiratory distress syndrome: Insights from the LUNG SAFE study

2020

Abstract Background Concerns exist regarding the prevalence and impact of unnecessary oxygen use in patients with acute respiratory distress syndrome (ARDS). We examined this issue in patients with ARDS enrolled in the Large observational study to UNderstand the Global impact of Severe Acute respiratory FailurE (LUNG SAFE) study. Methods In this secondary analysis of the LUNG SAFE study, we wished to determine the prevalence and the outcomes associated with hyperoxemia on day 1, sustained hyperoxemia, and excessive oxygen use in patients with early ARDS. Patients who fulfilled criteria of ARDS on day 1 and day 2 of acute hypoxemic respiratory failure were categorized based on the presence o…

Mitochondrial DNA haplogroups J and T increase the risk of glioma.

2021

The presence of different sets of mitochondrial polymorphisms generated by the accumulation of mutations in different maternal lineages has allowed differentiating mitochondrial haplogroups in human populations. These polymorphisms, in turn, may have effects at the phenotypic level, considering a possible contribution of these germinal mutations to the development of certain diseases such as cancer. The main goal of the present study is to establish a possible association between mitochondrial haplogroups and the risk of suffering glioma. Blood samples were obtained from 32 patients from Catalonia (Spain) diagnosed with different grades of glioma (II, III and IV), according to the World Hea…

Molecular polymorphism of the ABO blood group: A study in Poland, Spain, and Andorra

2014

Objectives The main goal of this study is to increase knowledge on the molecular level of the ABO blood group system in Europe by providing data for Poland, Spain, and Andorra populations. Methods A total of 172 oral scrapings samples from individuals of Polish origin, 108 peripheral blood samples of autochthonous individuals from the province of Zamora (Spain), and 81 peripheral blood samples from individuals with Andorran origin, were analyzed. Molecular characterization of the allelic variants was performed by the analysis of exons 6 and 7 of the ABO gene. Results Seven common alleles were identified, namely: A101, A102, A201, B101, O01, O02, and O03. Less common variants (O05, O09, O21,…

Validation and utility of ARDS subphenotypes identified by machine-learning models using clinical data: an observational, multicohort, retrospective …

2022

Item does not contain fulltext BACKGROUND: Two acute respiratory distress syndrome (ARDS) subphenotypes (hyperinflammatory and hypoinflammatory) with distinct clinical and biological features and differential treatment responses have been identified using latent class analysis (LCA) in seven individual cohorts. To facilitate bedside identification of subphenotypes, clinical classifier models using readily available clinical variables have been described in four randomised controlled trials. We aimed to assess the performance of these models in observational cohorts of ARDS. METHODS: In this observational, multicohort, retrospective study, we validated two machine-learning clinical classifie…

Outcomes of Patients Presenting with Mild Acute Respiratory Distress Syndrome: Insights from the LUNG SAFE Study

Editor's Perspective What We Already Know about This Topic Hospital mortality in acute respiratory distress syndrome is approximately 40%, but mortality and trajectory in "mild" acute respiratory distress syndrome (classified only since 2012) are unknown, and many cases are not detected What This Article Tells Us That Is New Approximately 80% of cases of mild acute respiratory distress syndrome persist or worsen in the first week; in all cases, the mortality is substantial (30%) and is higher (37%) in those in whom the acute respiratory distress syndrome progresses Background: Patients with initial mild acute respiratory distress syndrome are often underrecognized and mistakenly considered …
