The Multicenter Topic Trial

January 11, 2022 updated by: Mark Dransfield, MD, University of Alabama at Birmingham

A Multicenter Randomized, Double-blind, Phase 2, Placebo Controlled Study to Determine the Safety and Efficacy of Ivacaftor (VX-770) for the Treatment of Chronic Obstructive Pulmonary Disease (The Multicenter Topic Trial)

The purpose of this protocol is to test the safety, pharmacokinetics, and pharmacodynamics of the Cystic fibrosis transmembrane conductance regulator (CFTR) potentiator, ivacaftor in patients with chronic obstructive pulmonary disease (COPD) and chronic bronchitis. This project will investigate the hypothesis that ivacaftor can augment CFTR activity in individuals with COPD who exhibit chronic bronchitis, resulting in meaningful improvements in epithelial function and respiratory health. The study is a multicenter, randomized, double-blind, placebo-controlled, stratified study of orally-administered ivacaftor.

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

Like CF, COPD is characterized by small airway mucus obstruction that is associated with accelerated loss of lung function and mortality. Our preliminary data indicate that cigarette smoke exerts deleterious effects on airway epithelial function including the reduction of CFTR activity, enhanced mucus expression, and a pronounced reduction in mucociliary transport (MCT). Preliminary data also indicate that approximately 50% of patients with COPD have reduced CFTR activity, as detected in the upper airways, lower airways, and sweat glands. Furthermore, CFTR dysfunction is independently associated with chronic bronchitis, can persist despite smoking cessation, and can be reversed by the CFTR potentiator ivacaftor (VX-770) in vitro by activating wild-type CFTR, resulting in a robust increase in MCT. Combined with unprecedented clinical improvement via augmented mucociliary clearance in CF patients with a responsive CFTR mutation treated with ivacaftor, these data indicate that CFTR represents a viable therapeutic target to address mucus stasis in a large subset of COPD patients (potentially representing over 4 million patients in the U.S. alone). This project will investigate the hypothesis that ivacaftor can augment CFTR activity in individuals with COPD who exhibit chronic bronchitis, resulting in meaningful improvements in epithelial function and respiratory health. Our initial pilot study in patients with COPD and chronic bronchitis demonstrated that ivacaftor was safe, demonstrated stable pharmacokinetics, and exhibited a trend towards efficacy in patient-reported outcomes (PROs) and sweat chloride. The current trial will test the safety, pharmacokinetics, and pharmacodynamics of ivacaftor in a larger number of COPD patients with chronic bronchitis and for a longer treatment period, evaluating the potential of CFTR potentiator therapy to address acquired CFTR dysfunction in this population and set the stage for larger and longer-term trials in the future.

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.
Interventional

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

40 years to 80 years (ADULT, OLDER_ADULT)

  • Documented history of drug abuse within the last year
  • Subjects should not have a pulmonary exacerbation or changes in therapy for pulmonary disease within 28 days before receiving the first dose of study drug.
  • Cirrhosis or elevated liver transaminases > 3X ULN
  • GFR < 50 estimated by Cockroft-Gault
  • Any illness or abnormal lab finding that, in the opinion of the investigator might confound the results of the study or pose an additional risk in administering study drug to the subject.
