Experimental: Active arm
Valaciclovir 1 gram orally three times daily for 8 weeks.
Participants will self-administer Valaciclovir 1 gram three times daily for 8 weeks.
Placebo Comparator: Placebo arm
Matching placebo capsules (containing Avicel blend). Two capsules three times daily for 8 weeks.
Drug: Placebo capsules (containing Avicel blend)
Participants will self-administer two matching placebo capsules (containing Avicel blend) three times daily for 8 weeks.
- Incidence of Serious Adverse Reactions (SARs) [ Time Frame: Up to 28 days after completion of the study drug ]The primary outcome measure will be drug safety of valaciclovir (1 gram three times daily for 8 weeks) as defined by the incidence of Serious Adverse Reactions (SARs).
- EBV viral load [ Time Frame: Change from baseline to 8 weeks. ]The primary efficacy outcome is suppression of Epstein-Barr virus in the sputum measured using quantitative PCR at baseline and 8 weeks.
- Forced expiratory volume in 1 second (FEV1) [ Time Frame: Change from baseline to 8 weeks ]Lung function measured by spirometry, the principal component will be the change in FEV1 from baseline to week 8.
- Drug tolerability as measured by the proportion of tablets self-administered. [ Time Frame: 8 weeks ]Drug tolerability will be measured by total number of tablets self-administered as a proportion of total number of tablets supplied.
- COPD assessment test (CAT) score [ Time Frame: Change from baseline to 8 weeks ]This instrument is a disease specific questionnaire that can quantify the impact of COPD on the patient's health. The CAT has a scoring range of 0-40. Higher scores indicate more severe impact of COPD.
- EQ-5D-5L health status questionnaire [ Time Frame: Change from baseline to 8 weeks ]The EQ-5D-5L is a standardised questionnaire designed to measure health status (quality of life) in patients. The EQ-5D-5L comprises five dimensions (mobility, self-care, usual activities, pain/discomfort and anxiety/depression). Each dimension may be scored from one to five enabling the description of 3125 different health states.
