Intervention model description: The decision to implement Kaftrio treatment is made completely independently of the decision to enter the study. The investigators will follow the requirements of the local approved Kaftrio SmPC for the patient management as detailed in the 'special warnings and precautions for use' (e.g. management of hepatic impairment, rash, ophthalmological monitoring, between others), and for the management of interaction with other medicinal products and other forms of interactions. The 12+ cohort will be enrolled first on the basis the drug will be approved for children aged 12 and over first. The 6-11 year cohort will only be enrolled when the license is extended to this age group, and treatment with Kaftrio will only occur in the context of prescription by a physician in compliance with marketing authorization and the SPC.
Primary purpose: OTHER

Brief summary: RECOVER is a prospective, multicenter observational study designed to measure the real world clinical effectiveness of elexacaftor, tezacaftor and ivacaftor triple combination therapy (Kaftrio) in people with cystic fibrosis over a two year period. Measured outcomes include measures of lung function, lung inflammation, lung imaging, abdominal symptoms, gut inflammation, liver function, pancreatic exocrine function, nasal inflammation, quality of life and adherence to therapy. The study will examine outcomes in children aged six years and above over a period of two years. The first phase of the study will commence in 2020, recruiting children 12 years and older who have started on clinical treatment with Kaftrio.

Detailed description: Our aim with RECOVER is to examine the clinical impact of Kaftrio on key clinical outcomes in people with CF in a real-world setting. For this study, in addition to some of the more traditional ways of monitoring clinical outcomes in people with CF such a standard lung function, nutrition, exacerbations and liver disease, we are proposing to include some novel outcome measures not typically used in clinical trials such as lung clearance index (LCI) and spirometry controlled chest CT.

By implementing an extensive study protocol that will include important outcomes in a number of areas of health in people with CF, and matching this to a comprehensive biosample collection plan, we will have the power to gain important insight into how Kaftrio works, and what impact it has on rescue of CFTR function in this group of people.

Data on the following outcomes will be collected during the study:

Lung Clearance Index Ultra-low dose, spirometry-controlled CT scanning Sweat Chloride Nasal Lavage (inflammatory markers and microbiome) Fraction of Exhaled Nitric Oxide (FeNO) Liver Ultrasound Liver examination (signs of liver disease) Sputum Collection (inflammatory markers and microbiome) Stool Collection (inflammation, microbiome, fecal elastase) Abdominal symptom questionnaire CFQ-R (quality of life) Adherence to treatment Height, weight, BMI Forced Expiratory volume in 1 second (FEV1) Microbiological culture of airway specimens (clinical laboratories at sites)

The Lead Investigator is Paul McNally, with Prof. Jane Davies as Co-Lead Investigator. The study will operate in collaboration with our academic and clinical partners and the CF registries in Ireland and the UK. The study is supported by the European CF Society Clinical Trials Network (ECFS-CTN). The study is being run as a CTIMP in the UK clinical sites, as determined by the MHRA. In the Irish sites, the HPRA has determined this study to be an observational research study.

Eligibility criteria: Inclusion Criteria:

Inclusion criteria People with CF aged 12 years and over: Participants may only be selected for inclusion in RECOVER if they have been independently determined by their treating physician to be suitable for treatment with Kaftrio in compliance with the official marketing authorization and summary of product characteristics (SPC). The decision to include participants in the study is independent of decision to prescribe Kaftrio. Participants will receive treatment only through prescription by their physician through usual clinical treatment pathways.

Children aged 6-11 years: Children aged 6-11 years will be included in the study only if and when Kaftrio is licenced, approved and funded for this age group. Participants may only be selected for inclusion in RECOVER if they have been independently determined by their treating physician to be suitable for treatment with Kaftrio in compliance with the official marketing authorization and summary of product characteristics (SPC). The decision to include participants in the study is independent of decision to prescribe Kaftrio. Participants will receive treatment only through prescription by their physician through usual clinical treatment pathways.

Subjects on Kaftrio In exceptional circumstances where baseline clinical data has been collected prior to the start of treatment either through clinical care or ethically approved research projects (including a cohort of subjects initially recruited to this study on the understanding that it was a non-regulated observational study) subjects already receiving Kaftrio may be recruited to this study and undergo on-treatment visits. Any additional patient data can only be added with written informed consent from the patients/parents concerned.

All Subjects (people with CF aged 12 years and over, children aged 6-11 years and subjects on Kaftrio) must be taking the full dose of Kaftrio (in accordance with the age appropriate posology in the SmPC).

All subjects must have a signed informed consent form and/or signed assent form when appropriate, as determined by the subjects age and individual site and country standards.

Male and female participants of childbearing potential must agree to adhere to contraception requirements as detailed in the local Kaftrio SmPC and in line with the standard of care.

Exclusion Criteria:

Patients not willing to comply with study procedures or assessments.

Individuals on clinical trials of investigational CFTR modulators.

Clinical instability at baseline assessments. Subjects undergoing an active exacerbation and at the beginning of their treatment should be excluded from the study as this is likely to skew the data.

Any contraindication to Katrio treatment as per the local approved SmPC.

Severe hepatic impairment.

Pregnant and breastfeeding women.
