Six-month freedom from treatment failure is an important end point for acute GVHD clinical trials.

ABSTRACT: We studied the American Society for Blood and Marrow Transplantation (ASBMT) 6-month (m) freedom from treatment failure (FFTF) as a predictor of survival for patients with acute GVHD (aGVHD) requiring treatment. Adult patients undergoing allogeneic hematopoietic cell transplant (HCT) from February 2007 to March 2009 who were enrolled in a prospective biomarker clinical trial and developed aGVHD requiring systemic corticosteroids by day +100 were included (N=44). Six-month FFTF was defined as per the ASBMT guidelines (absence of death, malignancy relapse/progression or systemic immunosuppression change within 6 months of starting steroids and before chronic GVHD development). aGVHD was treated with systemic corticosteroids in 44 patients. Day 28 response after steroid initiation (complete response+very good partial response+partial response) occurred in 38 (87%) patients, but only 28 (64%) HCT recipients met the 6-m FFTF end point. Day 28 response predicted 6-m FFTF. Achieving 6-m FFTF was associated with improved 2-year (y) OS (81% vs 48%; P=0.03) and decreased 2-y non-relapse mortality (8% vs 49%; P=0.01). In multivariate analysis, 6-m FFTF continued to predict improved OS (hazard ratio, 0.27; P=0.03). The 6-m FFTF end point measures fixed outcomes, predicts long-term therapeutic success and could be less prone to measurement error than aGVHD clinical response at day 28.

Project description:BackgroundThe primary cause of ischemic heart failure (HF) is myocardial infarction (MI) resulting in left ventricle (LV) wall motion abnormality secondary to ventricular remodeling. A prospective, nonrandomized study conducted in China was designed to assess safety and efficacy of the percutaneous ventricular restoration therapy using Parachute device (CardioKinetix, Inc., CA, USA) in ischemic HF patients as a result of LV remodeling after anterior wall MI.MethodsThirty-one patients with New York Heart Association (NYHA) Class II, III ischemic HF, ejection fraction between 15% and 40%, and dilated akinetic or dyskinetic anterior-apical wall without the need to be revascularized were enrolled from seven sites in China from October to December 2014. The Parachute device was implanted through femoral artery. All patients received low-dose aspirin and anticoagulation with warfarin for at least 12 months postdevice implantation. The primary end-point was the assessment of efficacy as measured by the reduction in LV end-systolic volume index (LVESVI) against baseline LVESVI at 3 months postdevice implantation, determined by the echocardiography and measured by echocardiography core laboratory. Quality of life was assessed using EQ-5D and visual analog scale (VAS). For quantitative data comparison, paired t-test (normality data) and signed-rank test (abnormality data) were used; application of signed-rank test was for the ranked data comparison.ResultsA change in LVESVI as measured by echocardiography from the preimplant baseline to 3-month postdevice implantation revealed a statistically significant reduction from 77.5 ± 20.0 ml/m2 to 53.1 ± 17.0 ml/m2 (P < 0.0001). The trial met its primary end-point. Of the 31 patients, the procedural success was 96.8%. Overall, NYHA HF class assessment results showed an improvement of more than half a class at 3 months (P < 0.001). Quality of life assessed by the VAS value increased 11.5 points (P < 0.01), demonstrating improvement at 3 months.ConclusionThe favorable outcomes observed in the high-risk patients provide reassuring safety and efficacy data to support adoption of this technology as a therapeutic option for ischemic HF patients.Trial registrationClinicalTrials.gov, NCT02240940; https://clinicaltrials.gov/ct2/show/NCT02240940.

Project description:INTRODUCTION: Acute kidney injury (AKI) has high incidence among the critically ill and associates with dismal outcome. Not only the long-term survival, but also the quality of life (QOL) of patients with AKI is relevant due to substantial burden of care regarding these patients. We aimed to study the long-term outcome and QOL of patients with AKI treated in intensive care units. METHODS: We conducted a predefined six-month follow-up of adult intensive care unit (ICU) patients from the prospective, observational, multi-centre FINNAKI study. We evaluated the QOL of survivors with the EuroQol (EQ-5D) questionnaire. We included all participating sites with at least 70% rate of QOL measurements in the analysis. RESULTS: Of the 1,568 study patients, 635 (40.5%, 95% confidence interval (CI) 38.0-43.0%) had AKI according to the Kidney Disease Improving Global Outcomes (KDIGO) criteria. Of the 635 AKI patients, 224 (35.3%), as compared to 154/933 (16.5%) patients without AKI, died within six months. Of the 1,190 survivors, 959 (80.6%) answered the EQ-5D questionnaire at six months. The QOL (median with Interquartile range, IQR) measured with the EQ-5D index and compared to age- and sex-matched general population was: 0.676 (0.520-1.00) versus 0.826 (0.812-0.859) for AKI patients, and 0.690 (0.533-1.00) versus 0.845 (0.812-0.882) for patients without AKI (P?<0.001 in both). The EQ-5D at the time of ICU admission was available for 774 (80.7%) of the six-month respondents. We detected a mean increase of 0.017 for non-AKI and of 0.024 for AKI patients in the EQ-5D index (P?=?0.728). The EQ-5D visual analogue scores (median with IQR) of patients with AKI (70 (50-83)) and patients without AKI (75 (60-87)) were not different from the age- and sex-matched general population (69 (68-73) and 70 (68-77)). CONCLUSIONS: The health-related quality of life of patients with and without AKI was already lower on ICU admission than that of the age- and sex-matched general population, and did not change significantly during critical illness. Patients with and without AKI rate their subjective health to be as good as age and sex-matched general population despite statistically significantly lower QOL indexes measured by EQ-5D.
