Active clinical trials for "Cystic Fibrosis"

In recent years, diabetes has emerged as one of the most significant co-diseases that many Cystic Fibrosis (CF) patients develop. Type 1 (T1D) and Type 2 (T2D) diabetes results when either the body does not make enough insulin or the body does not respond correctly to this insulin, respectively. Insulin is a hormone which is made by cells in the pancreas and helps carry glucose (sugar) from the food we eat to the cells of the body for energy. While cystic fibrosis related diabetes (CFRD) has many features similar to both T1D and T2D, patients with CF may not have the same symptoms as either T1D or T2D patients. Currently, there is little understanding of CFRD and the best options for treatment remain unclear. The purpose of this research study is to examine and understand the various mechanisms that contribute to CFRD and gain a better understanding of potential means to treat CFRD. In particular, we plan to study the effects of incretin hormones that can enhance insulin production in CF patients. Enrollment is complete for the protocol as initially written. In order to further study the role of the incretin hormone on Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) function , we have received approval to extend our investigation to include the following study groups: Cystic Fibrosis participants with normal glucose tolerance Non-Cystic Fibrosis controls

Five Cystic Fibrosis (CF) centers, key stakeholders, and a palliative care institute have collaborated to create a novel primary palliative care intervention for patients with CF, "Improving Life with CF: A Primary Palliative Care Partnership," and established the infrastructure and support necessary for a follow-on implementation study. This intervention provides a framework for a nationally generalizable model to improve best practices in generalist-level palliative care in CF. Objectives: Aim 1: Implement a primary palliative care intervention comprising screening-and-triage workflows, best practice treatment guides for high frequency problems, patient/family and provider education, and a quality improvement (QI) toolkit. Aim 2: Evaluate feasibility, uptake, and preliminary outcomes during a multisite pragmatic, implementation trial of the intervention at 5 diverse Cystic Fibrosis (CF) Centers. Subaim 2.1: Evaluate feasibility and uptake as measured by rates of screening and treatment delivery. Hypothesis 1: Related to feasibility and uptake of the intervention: > 80% of individuals with CF of all ages will receive an annual palliative care screening. > 25% of individuals with CF will receive a palliative care screening prompted by hospitalization, new diagnosis of CF-Related Diabetes, need for transplantation, or another disease- or treatment-specific trigger. Hypothesis 2: Related to provider education: a) > 80% will access >1 training(s) (on-demand webinars or in-service by trained site educators). Subaim 2.2: Evaluate data on preliminary outcomes for individuals with CF by comparing ratings on patient- and caregiver-reported outcome measures (e.g., Integrated Palliative Care Outcome Scale, Cystic Fibrosis Questionnaire-Revised, Memorial Symptom Assessment Scale-Cystic Fibrosis, and Brief Assessment Scale for Caregivers) during the trial to baseline ratings and exploring covariates of change (age, race/ethnicity, gender, disease severity, CFTR modifier treatment, psychological distress, and varied indicators reflecting intervention implementation).

This study is a cooperative investigation funded by the NIH. The project is a collaboration among three major NIH Clinical Translational Science Awardees: 1) UCI (lead site with its affiliate CHOC), 2) Northwestern University (with its affiliate Lurie Children's Hospital), and 3) USC (with its affiliate Children's Hospital of Los Angeles). There is an increasing number of children who, through medical advances, now survive diseases and conditions that were once fatal, but which remain chronic and debilitating. A major challenge to improve both the immediate and long term care and health of such children has been the gap in our understanding of how to assess the biological effects of exercise. Like otherwise healthy children, children with chronic diseases and disabilities want to be physically active. The challenge is to determine what constitutes safe and beneficial level of physical activity when the underlying disease or condition [e.g., cystic fibrosis (CF) or sickle cell disease (SCD)] imposes physiological constraints on exercise that are not present in otherwise healthy children. Current exercise testing protocols were based on studies of athletes and high performing healthy individuals and were designed to test limits of performance at very high-intensity, unphysiological, maximal effort. These approaches are not optimal for children and adolescents with disease and disability. This project (REACH-Revamping Exercise Assessment in Child Health) is designed to address this gap. Cohorts of children will be identified with two major genetic diseases (CF and SCD) and measure exercise responses annually as they progress from early puberty to mid or late puberty over a 3-4year period. In addition, in the light of the pandemic, a group of children will be added who were affected by SARS-CoV-2 and investigate their responses to exercise. SARS-CoV-2 has similar long-term symptoms than CF and SCD have. Novel approaches to assessing physiological responses to exercise using advanced data analytics will be examined in relation to metrics of habitual physical activity, circulating biomarkers of inflammation and growth, leukocyte gene expression, and the impact of the underlying CF, SCD or SARS-CoV-2 condition. The data from this study will help to develop a toolkit of innovative metrics for exercise testing that will be made available to the research and clinical community.

There is established evidence that patients with Cystic Fibrosis (CF) may have altered antibiotic pharmacokinetics compared with non-CF patients. Imipenem/cilastatin/relebactam is a novel broad spectrum intravenous beta-lactam/beta-lactamase inhibitor combination antibiotic with potent activity against multidrug resistant Gram-negative bacteria, including imipenem non-susceptible Pseudomonas aeruginosa. Relebactam has also been shown to restore imipenem activity in Burkholderia cepacia complex, a group of opportunistic multidrug resistant pathogens that commonly infect patients with CF. This study will determine the pharmacokinetics and tolerability of imipenem/cilastatin/relebactam in 16 adolescent and adult patients with CF acute pulmonary exacerbations at one of seven participating hospitals in the US, with exploratory aim of reporting relative percent increase in FEV1 from pre- to post-treatment and return to baseline FEV1 after treatment with imipenem/cilastatin/relebactam for acute pulmonary exacerbations due to P. aeruginosa in patients with CF. Patients will receive a 10-14 day course of imipenem/cilastatin/relebactam, dosed according to renal function every 6 hours over 30 mins, with or without adjunctive aminoglycoside or fluoroquinolone therapy per local hospital guidelines. Blood will be sampled during one dosing interval at steady-state (i.e. after at least 3 doses) to determine concentrations and pharmacokinetics of imipenem and relebactam. Relative change in pulmonary function will be assessed two weeks after end of therapy. Safety and tolerability will be assessed throughout the duration of the study.

This is a prospective, open-label, multicenter study (1 year) with 50 patients with cystic fibrosis for whom treatment with KAFTRIO® is prescribed.Cystic fibrosis is a rare autosomal recessive hereditary disease linked to a mutation of the CFTR (Cystic Fibrosis Transmembrane Regulator) protein gene. For the majority of patients, no treatment with a CFTR protein modulator was available until the arrival of the KAFTRIO® triple therapy (ivacaftor/tezacaftor/elexacaftor). Clinical studies on this triple therapy demonstrate significant improvements in FEV (forced vital capacity) and also very rapid health improvement of patients. However, there is a lack of data recorded in real life at home by patients to trace the evolution curves of health parameters and patient perceptions from the first days after initiation of treatment. The PHEAL-CR-K application, specially developed for the study, makes it possible to collect physiological parameters and perceptions collected via connected objects or declared manually in the application. These data will reflect the evolution of the parameters from the start of the treatment and over a period of 3 months. In addition, the composition of volatile organic compounds (VOCs) of the air exhaled in the early phase of treatment with KAFTRIO® will be monitored for the group of patients followed at Foch Hospital. Exhaled air is an ideal biological fluid for clinical monitoring (non-invasive collection and real-time analysis). In cystic fibrosis, biomarkers in the exhaled air have been correlated with functional and clinical parameters. The objective is to collect the air exhaled before initiating treatment with KAFTRIO® and during treatment, to identify VOCs whose expression would be modified early. Changes in the composition of the exhaled air will be correlated with follow-up clinical data collected with the PHEAL-CR-K application and with functional data obtained during measurements of breath by spirometry (FEV) and sweat concentrations of chloride ions collected at the during a sweat test. The identified COVs could become early predictive biomarkers of clinical response.

The goal of this study is to execute a small clinical proof of concept trial: To examine the effects of losartan on mucociliary clearance (MCC) in patients not eligible for CFTR rescue therapies

Lung transplant is an option for treating end-stage lung disease in cystic fibrosis (CF). In the United States, more people with CF and low lung function die each year than undergo lung transplant. More than half of people with CF who die without a lung transplant were never referred for consideration. Patient preference not to undergo lung transplant may account for 25-40% of decisions to defer referral. Rates of death without transplant are higher for people with CF who are members of marginalized communities, including those with Black race, Hispanic ethnicity, or low socioeconomic status. Increasing awareness of lung transplant among people with CF, and promoting understanding of the risks and benefits of transplant, can potentially reduce the number of people with CF who die without a lung transplant. The CF Foundation (CFF) lung transplant referral guidelines were developed to optimize the timing of referral for lung transplant. These guidelines recommend annual conversations with people with CF once their forced expiratory volume in one second (FEV1) is <50% predicted. Considering lung transplant as a treatment option before it is medically needed will allow more time to learn about lung transplant and address any barriers to lung transplant that may exist. Investigators are interested in understanding how people with CF use lung transplant educational resources and how one prepares for having discussions and/or making decisions about lung transplant as a treatment option for advanced CF. The purpose of this study is to test whether a research website improves patient preparedness for discussions about lung transplant. Investigators also aim to understand whether there are unique factors that affect people with CF from communities with decreased access to transplant ("communities of concern"). Study involvement will span 6 months and study activities will involve the following: Four Zoom research sessions (15-30 minutes each) Survey assessments Access to a research website that contains educational resources about lung transplant Audio recording of a routine CF clinic visit to determine if and how lung transplant is discussed between a participant and his/her/their CF doctor

The pandemic forced us to develop home follow-up for patients with chronical diseases . In the same time, the new era of treatment for cystic fibrosis considerably improves the health of patients with this pathology. This study aims to assess the satisfaction of patients and care providers for an alternated follow-up between tele-consults and in-hospital consults during one year for patients with cystic fibrosis treated by Kaftrio® since at least one year and stable.

The purpose of this prospective study is to analyze function and phenotype of blood neutrophils in cystic fibrosis patients and the impact of Pseudomonas aeruginosa chronic infection, treatment with CFTR modulators and acute exacerbation on blood neutrophils phenotype and function.

The exercise test provides prognostic information about clinical outcomes and quality of life to optimize care for cystic fibrosis patients (pwCF). The exercise test identifies the causes of exercise restriction, adverse exercise reactions, and exercise-related symptoms. The results help to determine and evaluate the impact of exercise programs at PWCF. Peak oxygen uptake (VO2peak) is a prognostic measure of maximum exercise capacity that usually worsens as CF lung disease progresses. The recommended gold standard exercise test at PWCF is a cardiopulmonary exercise test (CPET) performed on a loop ergometer to assess VO2peak and cardiopulmonary responses to exercise. the recommended incremental protocol, consisting of 1-minute phases, should reach VO2peak within 8-12 minutes. Trained operators perform cpets with complex and expensive laboratory equipment, and it is inaccessible and little used by many people internationally. Step tests are low-cost, portable, easily standardized and require minimal space to perform. The 3-Minute Step Test (3MST) is an externally paced test for the assessment of exercise tolerance set at 30 steps/minute for 3 minutes. In adults with CF, 3MST is useful for assessing oxygen desaturation and predicting future increased use of healthcare services. Limitations include the ceiling effect in less severe CF lung disease, and it is very difficult for some with more advanced lung disease. An incremental maximum A-STEP step test has been developed to assess exercise capacity in the CF lung disease December, without floor or ceiling effects, within clinical space constraints and the need for strict infection prevention. A-STEP is a new incremental maximum step test to assess exercise capacity in PWCF without floor or ceiling effects, as an alternative field test to CPET.
