Protein Biomarker Discovery and Validation in Chronic Obstructive Pulmonary Disease (COPD) And Asthma (Proteomics)

April 14, 2023 updated by: The University of Texas Medical Branch, Galveston

Protein Biomarker Discovery and Validation in COPD And Asthma

The purpose of the study is to better understand proteomics of asthma and COPD, and response to therapy. There are two Phases to this study broken into two arms. In Phase I, we propose is to use discovery proteomics and techniques to identify protein expression signatures. Subjects who complete Phase I are eligible, but not required, to enroll in Phase II. In Phase II, we propose to establish and validate the predictive value of protein signatures for treatment responses using inhaled corticosteroids.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

There are two Phases to this study broken into two arms. In Phase I, our propose to use discovery proteomics and high throughput techniques to identify protein expression signatures. The total planned size of Phase I is 100 patients. Patients will be divided into two arms based on disease status (COPD or asthma). Active smoking will be defined as daily use of cigarettes, pipes, cigarillos or cigars at time of entry into the study and through duration of study. No active smoking defined as never smoking or having stopped smoking for 5 years or greater.

In the Phase II, we aim to establish and validate the predictive value of proteomic signatures for therapeutic responses using inhaled corticosteroids. For Phase II, subjects who completed Phase I are eligible, but not required to participate in Phase II.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
9

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients will be divided into two identical arms based on smoking status. One arm will contain subjects who are active smokers and the other arm will contain subjects with no active smoking.

Each arm will contain 50 subjects, 26 with COPD (Stage II and III with 13 subjects in each) along with 24 asthmatics (Mild to Moderate disease with 12 subjects in each).
