NCT03591978

Brief Summary

We have demonstrated for the very first time that it is possible to isolate CPCs (circulating pulmonary cells) in patients with COPD in a sample of 17 patients (with a recovery rate of nearly 40%) and none of 10 healthy, non- smokers controls with a patented method \[provisional Spanish Patent Application (P201730724)\], based on liquid biopsy methodology (Romero Palacios et at, submitted 2017), showing that patients with COPD and isolation of CPCs have a more severe disease (expressed as higher BODEx index) and a trend towards a higher rate of decline of lung function as well as an increased rate of exacerbations, suggesting that CPCs isolation could be of value as a diagnostic and prognostic tool identifying patients with more active diseases. However, due to the small sample, no definitive conclusions could be made. Moreover, as there were no healthy smokers included in this study, we couldn´t evaluate if CPCs could be isolated in this type of population. The fact that CPCs could be isolated in a group of patients with COPD and its relationship with greater severity suggests that this could be a marker of progression of the disease and could detect those patients more likely to benefit from newer antiinflamatory therapies(17)

Outcome Measures

Primary Outcomes (1)

  • Evaluate the prevalence of CPCs isolation in peripheral blood from COPD patients, smoking and non-smoking healthy controls with a patented liquid-biopsy technique.

    1 year

Secondary Outcomes (6)

  • Establish if there are differences between CPCs isolation rates from COPD patients, smoking and non-smoking healthy controls

    1 year

  • Evaluate the relationship between CPCs isolation and the degree of parenchymal destruction and empyshema expresed as DLCO and kCO

    1 year

  • Evaluate the relationship between CPCs isolation and emphysema degree expressed as CT scan measurements (% LAA).

    1 year

  • Evaluate the relationship between historical FEV1decline and CPCs isolation in COPD patients.

    2 year

  • Evaluate the relationship between prospective 1 year FEV1 decline and CPCs isolation in COPD patients.

    1 year

  • +1 more secondary outcomes

Other Outcomes (5)

  • Evaluate the rate of moderate and severe exacerbations during 1-year follow up between COPD patients with and without CPCs isolation after adjustment for confounding variables

    1 year

  • Evaluate the time to first moderate and severe exacerbation during 1-year follow up between COPD patients with and without CPCs isolation after adjustment for confounding variables.

    1 year

  • Evaluate if there are differences in the rate of CPCs isolation between those patients with early onset COPD (defined as those with COPD before 60 years of age) and those with normal onset COPD (defined as those with COPD after 60 years of age).

    1 year

  • +2 more other outcomes

Sampling MethodProbability Sample
Study Population

20 healthy non-smokers, 30 healthy smokers and 100 patients with COPD (70 patients with mild to moderate disease- 35 of them below 60 years-old and 35 above 60 years-old-, and 30 patients with severe to very severe COPD -15 of them below 60 years-old and 15 above 60 years-old).

You may qualify if:

  • Adults of \>35 years-old.
  • Patients who have given written informed consent
  • Absence of respiratory infection or COPD exacerbation in the 4 previous weeks to baseline visit.

You may not qualify if:

  • Other respiratory condition apart from COPD, such as previous diagnosis of bronchial asthma, obstructive sleep apnoea, idiopathic pulmonary fibrosis, pulmonary tuberculosis, alpha1 antitrypsin deficiency.
  • Current or previous cancer history (even if the patient has been diagnosed \>5 years and there is no evidence of recurrence of disease).
  • Unwillingness to perform pulmonary function test or CT scan.
  • Participation in another investigational study or clinical trial.
