Brief Summary:
COPD is a major public health problem and will shortly become the third most common cause of global mortality. There are currently no treatments that can meaningfully alter the progression of COPD or the time to death. Consequently novel therapeutic strategies for COPD are urgently required. This will be a randomised, double-blind, placebo-controlled, trial of Epstein-Barr virus suppression in COPD. Participants will be randomised to receive valaciclovir 1 gram three times daily for 8 weeks or matching placebo. The study will measure EBV suppression using quantitative PCR. Secondary outcomes will include Lung function quality of life and drug tolerability. The exploratory analysis will evaluate biomarkers of airway inflammation within the sputum and blood.

Arm Intervention/treatment
Experimental: Active arm
Valaciclovir 1 gram orally three times daily for 8 weeks.
Drug: Valaciclovir
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.

Primary Outcome Measures :
  1. 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).

  2. 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.

Secondary Outcome Measures :
  1. 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.

  2. 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.

Other Outcome Measures:
  1. 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.

  2. 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.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Age over 18 years.
  2. Clinical diagnosis of COPD as defined by the Global Initiative for Chronic Obstructive Lung Disease criteria (FEV1/FVC <70%) with GOLD 2 and GOLD 3 airflow obstruction (FEV1 30-80% predicted) with significant symptoms.
  3. Presence of Epstein-Barr virus on sputum PCR analysis.

Exclusion Criteria:

  1. Respiratory failure (defined as long-term oxygen therapy).
  2. An acute exacerbation of COPD in the previous month (defined as an acute, sustained worsening of symptoms that is beyond normal day-to-day variations).
  3. A diagnosis of asthma.
  4. Patients with known hypersensitivity to valaciclovir or aciclovir.
  5. Patients unable to swallow study drug capsules.
  6. Established diffuse interstitial lung disease (e.g. Idiopathic Pulmonary Fibrosis).
  7. Established diagnosis of symptomatic bronchiectasis.
  8. Patients known to be pregnant or breastfeeding.
  9. Patients with an estimated creatinine clearance less than 50ml/minute.
  10. Known participation in investigational medicinal product trials within 30 days.
  11. Patients who do not adequately understand verbal or written information.
  12. Concomitant use of nephrotoxic medicinal products or medicines associated with altered renal tubular secretion. These include aminoglycosides, organoplatinum compounds, methotrexate, pentamidine, foscarnet, ciclosporin, tacrolimus,tenofovir, cimetidine and probenecid. As iodinated contrast used in radiological examinations can be nephrotoxicity patients with planned radiological contrast studies will be deferred for a reasonable time until after their contrast.
  13. For the exploratory bronchoscopy sub-study patients will require adequate oxygen saturations, FEV1 >0.5 L and will not be performed while patients are taking aspirin or clopidogrel (BTS guidelines 2013).
