Study of COPD Subgroups and Biomarkers (SPIROMICS)

Subpopulations and Intermediate Outcome Measures in COPD Study

SPIROMICS I, SPIROMICS II, and SPIROMICS III are longitudinal observational studies of Chronic Obstructive Pulmonary Disease (COPD) cohort.

SPIROMICS I had two primary aims: (1) To find groups of patients with COPD who share certain characteristics; (2) To find new ways of measuring whether or not COPD is getting worse and to provide new ways of testing whether a new treatment is working.

SPIROMICS II had three primary aims: (1) To define the natural history of "smokers with symptoms despite preserved spirometry" and characterize the airway mucus abnormalities underlying this condition; (2) To determine the radiographic precursor lesion(s) for emphysema and identify the molecular phenotypes underlying airway disease and emphysema; (3) To advance understanding of the biology of COPD exacerbations through analysis of predisposing baseline phenotypes, exacerbation triggers and host inflammatory response.

SPIROMICS III has three primary aims: (1) To identify the main forms of smoking-related airway disease that are caused by pathological airway mucus, their biological underpinnings, and their physiological significance; (2) To identify longitudinal trajectories in established and novel CT measures of emphysema, test how they predict COPD progression, and define their underlying biology; (3) To identify environmental and social determinants of health that impact disease severity and progression and their influence on lung structure, biology, and health disparities in COPD.

Study Overview

• Status: Active, not recruiting
• Conditions: Chronic Obstructive Pulmonary Disease; Emphysema; COPD; Chronic Bronchitis

Detailed Description

SPIROMICS was initially funded through contracts from the NIH. That phase of SPIROMICS is now referred to as SPIROMICS I. SPIROMICS II was funded as a grant from the NIH to continue the longitudinal observation of the SPIROMICS cohort recruited in SPIROMICS I. The current phase, referred to as SPIROMICS III, is funded through a contract from the NIH to continue the longitudinal observation of the SPIROMICS cohort that remain active (not withdrawn, lost to follow-up, or deceased).

Description of SPIROMICS I:

The purpose of SPIROMICS was to learn about chronic obstructive pulmonary disease (COPD), which is sometimes called emphysema or chronic bronchitis. Millions of Americans have COPD, and it is the fourth leading cause of death in the country. The most common cause of COPD is cigarette smoking, although not all smokers get COPD. The discovery of new treatments for COPD has been slowed by a poor understanding of different types of COPD and a lack of ways to measure whether or not COPD is getting worse.

The study had two main goals. The first was to find groups of patients with COPD who share certain characteristics. Certain groups may respond differently to certain treatments. The second was to find new ways of measuring whether or not COPD is getting worse. This would provide new ways of testing whether a new treatment is working.

SPIROMICS I had three sub studies and two key ancillary studies.

Sub studies:

1. Repeatability Substudy: The entire baseline clinic visit was repeated on 100 participants on a volunteer basis. The goal of this substudy was to determine reliability of measurement procedures.
2. Bronchoscopy Substudy: ~300 participants were enrolled for two additional study visits, including a bronchoscopy. The goal of this substudy was to collect and assess biological specimens and relate those results to clinical measurements.
3. Exacerbation Substudy: ~400 participants were enrolled in this substudy. A daily symptom diary was collected on all participants. Participants were also seen in the clinic during a pulmonary exacerbation. The goals of this substudy were to 1) better understand the relationship between symptoms and exacerbations and 2) obtain clinical data and specimens during a pulmonary exacerbation.

Ancillary Studies:

1. Air Pollution Ancillary Study: The SPIROMICS Air Pollution ancillary study used state-of-the art air pollution exposure assessments to determine individual-level outdoor and indoor air pollution exposure. The goals of this substudy were to determine the effect of long-term air pollution exposure on COPD morbidity and to determine whether short-term changes in outdoor air pollution are associated with changes in COPD morbidity.
2. Parametric Response Mapping in COPD: The Parametric Response Mapping (PRM) in COPD ancillary study collected an additional CT scan during the final study visit and used a new analysis technique (PRM) to assess the functional small airways of the lung and emphysema.

Description of SPIROMICS II:

Aim 1 was to define the natural history of "smokers with symptoms despite preserved spirometry" and characterize the airway mucus abnormalities underlying this condition. Aim 2 was to determine the radiographic precursor lesion(s) for emphysema and identify the molecular phenotypes underlying airway disease and emphysema. Aim 3 was to advance understanding of the biology of COPD exacerbations through analysis of predisposing baseline phenotypes, exacerbation triggers and host inflammatory response.

SPIROMICS II continued follow-up of active participants, with no new enrollment. Each participant had one clinic visit at 5-7 years of follow-up from SPIROMICS I baseline and was contacted by telephone every 4 months to assess respiratory health status.

Description of SPIROMICS III:

Aim 1 is to identify the main forms of smoking-related airway disease that are caused by pathological airway mucus, their biological underpinnings, and their physiological significance. Aim 2 is to identify longitudinal trajectories in established and novel CT measures of emphysema, test how they predict COPD progression, and define their underlying biology. Aim 3 is to identify environmental and social determinants of health that impact disease severity and progression and their influence on lung structure, biology, and health disparities in COPD.

SPIROMICS III will enroll and consent approximately 1800 participants to conduct (a) a single in-person clinic visit at approximately 11-16 years of follow-up for those originally enrolled into SPIROMICS I and approximately 5-6 years of follow-up for those originally enrolled into SOURCE (and MAP COPD) (NCT05033990), (b) follow-up telephone calls every 4 months to assess respiratory health status, and (c) to assess indoor and outdoor environmental monitoring.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Morbidity	Morbidity in SPIROMICS will primarily be measured by assessing acute exacerbations in the SPIROMICS cohort.	Through study completion, an average of 18 years.
Lung Function	COPD is characterized by physiological problems, such as airflow limitations and abnormalities of gas exchange and lung hyperinflation. These features of lung function are accessed objectively in the laboratory setting using spirometry/plethysmography, which can measure such parameters as FEV1 (forced expiratory volume in one second), FVC (forced vital capacity or total volume of air exhaled after full inspiration), FRC (functional residual capacity or volume of gas remaining in the lung at the end of tidal expiration), and IC (inspiratory capacity or maximum volume of gas that can be inspired from end-tidal expiration). The FDA preferred primary endpoint for assessment of alteration in disease progression in COPD is serial measurements of FEV1 over three years.	Through study completion, an average of 18 years.
Mortality	Deaths of SPIROMICS participants will be identified during follow-up calls and attempts to schedule clinic exams during the three-year study period, and deaths will be recorded in the clinical database. The cause of death will be determined via chart review and adjudication, and deaths attributable to COPD worsening or exacerbation will be recorded as confirmed clinical endpoints, in addition to contributing to the endpoint of all-cause mortality.	Through study completion, an average of 18 years.
SPIROMICS III: Radiology - Emphysema Volume	Percent Emphysema (percent <-950HU)	Through study completion, an average of 18 years.
SPIROMICS III: Radiology - Functional Small Airway Disease through Parametric Response Mapping (PRM)	PRM metrics will be used to non-invasively evaluate the regional structural heterogeneity of the lung, including small airways disease and emphysema, and its relationship to clinical measurements. The metric is PRMfSAD.	Through study completion, an average of 18 years.
SPIROMICS III: Radiology - Functional Small Airway Disease through Disease Probability Method (DPM)	Patients undergo both full-inspiration and full-expiration chest CT scans. These scans are coregistered-aligned voxel-by-voxel-to allow for direct comparison of lung tissue characteristics between breathing phases. Each voxel (3D pixel) in the lung is classified into one of three categories: Normal: No signs of disease, Emphysema: Identified by low attenuation on inspiratory CT, Gas Trapping (SAD): Identified by abnormal retention of air on expiratory CT without emphysema features. The proportion of voxels classified as emphysema, gas trapping, or normal is calculated.	Through study completion, an average of 18 years.
SPIROMICS III: Radiology - Airway Wall Thickness	Pi10 as a measure of airway wall thickness	Through study completion, an average of 18 years.
SPIROMICS III: Physiology - Lung function (Spirometry)	Lung function will be assessed as FEV1 through spirometry using forced and slow vital capacity before and after bronchodilator (BD) administration.	Through study completion, an average of 18 years.
SPIROMICS III: Physiology - Lung function (Respiratory Oscillometry)	Assessment of lung function through respiratory oscillometry.	Through study completion, an average of 18 years.
SPIROMICS III: Biological - Mucin concentrations	Mucus samples obtained from sputum, bronchial brushings, and Bronchoalveolar Lavage (BAL) will be analyzed for total mucin concentration.	Through study completion, an average of 18 years.
SPIROMICS III: Biological - MUCQ index	The MUCQ index which integrates mucin concentration with MUC5AC/MUC5B ratios will be calculated and provide more detailed understanding of mucin composition and regulation. The formula MUCQ=[total mucin] x [5AC]/[MUC5B] / 100 will be used.	Through study completion, an average of 18 years.

Plan for Individual participant data (IPD)

• Plan to Share Individual Participant Data (IPD)?: YES
• IPD Plan Description: Data and biospecimens collected in SPIROMICS I were submitted to the NHLBI data and biospecimen repository known as BioLINCC. Data, including genetics and genomics, from SPIROMICS I and SPIROMICS II are submitted to the NIH data repository known as dbGaP. All data and biospecimens are also available through the SPIROMICS Genomics and Informatics Center (GIC) at the Collaborative Studies Coordinating Center (CSCC) at The University of North Carolina at Chapel Hill, by request, and according to study policies and procedures.
• IPD Sharing Time Frame: Data and biospecimens from SPIROMICS I and SPIROMICS II are currently available and will remain available indefinitely. The same for data and biospecimens from SPIROMICS III on an annual basis.

IPD Sharing Access Criteria

Access criteria for data from BioLINCC are determined by NHLBI, not by the SPIROMICS Investigators.

Criteria, policies, and procedures for obtaining data and biospecimens directly from the SPIROMICS Genomics and Informatics Center (GIC) at the Collaborative Studies Coordinating Center (CSCC) at The University of North Carolina at Chapel Hill are available on the web site listed below.
