extension observational phase up to 1 year. The trial will include Canadian hospital sites enrolling 124 patients. Patients ≥18 years old with either refractory or unexplained chronic cough will undergo 1:1:1:1 randomization to receive either low-dose morphine (up to 5 mg twice daily) or pregabalin (up to a maximum tolerated dose of 150 mg twice daily) with or without cough control therapy. The cough control therapy will consist of five virtual sessions delivered over 6 weeks by a trained physiotherapist and speech-language pathologist.

Those who, in the opinion of the investigator, have previously tried low-dose morphine, pregabalin, and/or CCT with full intervention fidelity for the treatment of RCC/UCC;\n2. Are currently taking morphine or pregabalin for the treatment of any indication (i.e., RCC/UCC or chronic pain);\\*\n3. Are currently taking other centrally-acting medication (i.e., gabapentin, amitriptyline, dextromethorphan) for the treatment of any indication (i.e., RCC/UCC, seizures, or depression);\\*\n4. Have a history of opioid or substance abuse that, in the opinion of the investigator, may interfere with the conduct of the study;\n5. Are a current smoker, or ex-smoker with a \\>20 pack-year history who have abstained from smoking for \\<6 months;\n6. Have cough due to angiotensin-converting enzyme inhibitor use;\n7. Have symptoms of an upper respiratory infection within the last month that have not resolved;\n8. Had an asthma exacerbation within the last month that requires an increase or start of an oral corticosteroid;\n9. Have other primary pulmonary disorders, including pulmonary embolism, pulmonary hypertension, lung cancer, cystic fibrosis, radiologically-proven emphysema, interstitial lung disease, or severe bronchiectasis;\n10. Have language, memory, cognitive, or psychiatric issues that may prevent optimal participation;\n11. Have creatinine clearance \\<15 mL/min, including individuals with end-stage renal disease who require hemodialysis or peritoneal dialysis;\n12. Have any other condition that, in the opinion of the qualified investigator, may adversely affect the participant's ability to complete the study or its measures or pose significant risk to the participant;\n13. Have participated in another clinical trial of an investigational medicinal product within 30 days;\n14. Pregnant or breastfeeding; or\n15. Females of child-bearing potential who:\n\n 1. Do not agree to use a medically approved method of birth control for the duration of the study. All hormonal birth control must have been in use for a minimum of 3 months.\n 2.

Females who are not of child-bearing potential will be defined as females who have undergone a sterilization procedure (e.g., hysterectomy, bilateral oophorectomy, bilateral tubal ligation, complete endometrial ablation) or have been post-menopausal for at least 1 year prior to screening.\n\n * Participants taking any of the above medications at baseline will only be eligible if they are willing and medically able to safely discontinue them at least 2 weeks prior to the first study visit.
