Trials Tracker

Welcome to the Trials Tracker, bringing together all the cystic fibrosis (CF) trials currently recruiting in the UK so that you can find clinical trials you can take part in both in your region and further afield. The Trials Tracker is a new resource that we’ll be developing over time based on your feedback.

Trial to Evaluate Efficacy and Safety of Lenabasum in Cystic Fibrosis

This is a Phase 2 multicenter, double-blind, randomized, placebo-controlled study assessing the efficacy and safety of lenabasum for the treatment of cystic fibrosis in patients 12 years of age or older. Approximately 415 subjects will be enrolled in this study

Glycaemic Index Dietary Education for glucose abnormalities in Cystic Fibrosis

Few people with Cystic Fibrosis have normal blood glucose control and these glucose abnormalities eventually progress to cystic fibrosis-related diabetes (CFRD), the most common complication of Cystic Fibrosis. People with Cystic Fibrosis are encouraged to consume a high calorie diet to maintain weight. This typically means eating food and drinks that are often high in fat and/or sugar. For people with Cystic Fibrosis who also need to control their blood glucose levels, high sugar intake can make this difficult. There is limited evidence to guide dietary therapy for blood glucose abnormalities in Cystic Fibrosis. Manipulating the glycaemic index (GI) and glycaemic load (GL) of what is consumed may be a possible area for intervention to improve blood glucose control without compromising energy intake. This study will explore the feasibility of delivering glycaemic index/glycaemic load dietary education (GLIDE) in a sample of 20 young people with CF and abnormal blood glucose control. GLIDE intervention will be implemented by participants for 12 weeks. Dietary intake and glycaemic control will be measured at baseline and at 12 week follow-up using an on-line dietary recording tool and continuous glucose monitoring, respectively. The primary objective of this study is to investigate the feasibility of GLIDE intervention in young people with CF and abnormal blood glucose control. Secondary objectives include measuring glycaemic control, energy and nutrient intake, body weight and lung function before GLIDE intervention and at 12-week follow-up.

    Restore CFTR Function


Lung clearance index (LCI) measure by multi-breath washout (MBW) has been shown to be sensitive and a non-invasive way of picking up early airways disease in infants with cystic fibrosis (CF). Abnormal measurements at a young age have been shown to track into later life and could identify children who need more aggressive treatment early. Currently there is a lack of data and suitable ways of performing this in multiple, non-specialised centres. This is a multi-centre longitudinal observational study of this measurement in children under 3 years of age with CF with a healthy control group and a disease comparison group of babies who are born early. A novel method for MBW in infants will be used which has been developed and assessed in a pilot study prior to this. We aim to show that LCI can be reliably measured across multiple centres using this method with high rates of success and that the measurements are repeatable in the short term (2-3 months). Any changes in this measurement in the CF infants and children will also be shown over 12-18 months. All parents will be consented prior to taking part and the children will be sedated as per local protocol at lower doses than usual. The CF children will be seen after recruitment, 2-3 months and 12-18 months later. The babies will be seen prior to discharge from the neonatal unit and 12 months later. The healthy children will be seen opportunistically when sedated for MRI scans in radiology and measurements taken whilst still asleep.
