Eligibility
Inclusion criteria
Inclusion criteria: 1. Patients =18 years old 2. Have COPD as the predominant respiratory diagnosis 3. Meet Medical Research Council (MRC) definition of chronic bronchitis, defined epidemiologically as cough and sputum production for =3 months per year in at least 2 consecutive years and/or have associated bronchiectasis on computed tomography of the chest 4. Self-reported difficulty in expectoration (determined from the medical notes and/or participant). If from the participant, this will be documented in the medical notes
Exclusion criteria
Exclusion criteria: Current participant exclusion criteria as of 16/12/2022: 1. Patients that do not have the capacity to consent (determined by clinician or member of the research team) 2. Patients with active malignancy 3. Patients with a solid organ transplant 4. Patients with active tuberculosis 5. Patients who are in end-of-life care 6. Patients who have had treatment with nebulised hypertonic sodium chloride, carbocisteine or any muco-active treatments within the past 7 days* 7. Patients who are established on long-term antibiotic therapy for less than 3 months 8. Patients who have had an exacerbation within the past 14 days requiring treatment with antibiotics and/or steroids** 9. Known contraindication or intolerance to nebulised 7% sodium chloride or carbocisteine or any hypersensitivity to the active ingredients or the excipients of carbocisteine 10. Active peptic ulceration; any known hereditary galactose intolerance, Lapp-Lactase deficiency or glucose-galactose malabsorption 11. Women who are pregnant or currently breastfeeding 12. Women of childbearing potential*** not taking appropriate contraception****. Contraception must be continued for a minimum of 30 days after the end of the IMP dosing schedule. 13. Participation in another Clinical Trial of an Investigational Medicinal Product (CTIMP) within the last 30 days 14. Previous recruitment to the study 15. Participants indicating that they are unable to comply with the study protocol prior to randomisation including those unable to complete participant questionnaires *If participants have been on treatment with nebulised 7% sodium chloride, carbocisteine or any muco-active treatments within the past 7 days, they need to come off these treatments for 7 days and remain clinically stable in order to be eligible for the study **14 days from the start of the recent exacerbation *** A woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle-stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormone replacement therapy. However, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient. ****Acceptable contraception in women of childbearing age is a “highly effective” contraceptive measure as defined by the Clinical Trials Facilitation Group and includes combined (oestrogen and progesterone containing) or progesterone-only contraception associated with inhibition of ovulation, or intrauterine device or bilateral tubal occlusion (http://www.hma.eu/fileadmin/dateien/Human_Medicines/01-About_HMA/Working_Groups/CTFG/2014_09_HMA_CTFG_Contraception.pdf). Previous participant exclusion criteria: 1. Patients that do not have capacity to consent (determined by clinician or member of the research team) 2. Patients with an active malignancy 3. Patients with a solid organ transplant 4. Patients with active tuberculosis 5. Patients who are in end-of-life care 6. Patients who have had treatment with nebulised hypertonic sodium chloride, carbocisteine or any muco-active treatments within the past 30 days* 7. Patients established on long-term antibiotic therapy for less than 3

Number of exacerbations over a one year period requiring antibiotic therapy and/or systemic steroid treatment measured using exacerbation diaries when exacerbation is reported by the patient 2.2. Time to first exacerbation requiring antibiotic therapy and/or systemic steroids over one year measured using exacerbation diaries when exacerbation is reported by the participant 2.3. Proportion of exacerbations needing antibiotic therapy over one year measured using exacerbation diaries when exacerbation is reported by the patient and concomitant medication recording 2.4. Number of upper respiratory tract infections (URTI) over a one year period) assessed using the Wisconsin Upper Respiratory Symptom Survey-24 (WURSS-24) 2.5.
