About this study

Official title: A Randomized, Double-blind, Sponsor Un-blinded, Placebo-controlled, Phase 2a Crossover Study to Evaluate the Effect of the TRPV4 Channel Blocker, GSK2798745, on Pulmonary Gas Transfer and Respiration in Patients With Congestive Heart Failure

This study is a single centre, randomised, double-blind, sponsor-unblinded, placebo-controlled, 2 by 2 crossover study in adults with heart failure. In blocking the TRPV4 ion channel and reducing pulmonary interstitial fluid, GSK2798745 may improve pulmonary function, respiration, and gas exchange as well as sleep-disordered breathing in patients with heart failure. Therefore, the current study is designed to investigate the effect of repeat administration of GSK2798745 on pulmonary gas exchange and pulmonary function.

A sufficient number of subjects with heart failure will be enrolled so that 12 subjects complete the two study periods and critical assessments. Subjects will be randomised to receive either GSK2798745 or placebo once daily for a period of 7 days in one treatment period and alternate study medication in the second treatment period. Both the treatment periods will be separated by a washout period of at least 14-days.

This study will consist of a Screening visit within 14 days of the start of Period I and two treatment periods wherein eligible subjects will be randomised to one of the two treatment sequences, a follow-up visit approximately 2 weeks after the completion of second study period. The total duration of the study is approximately 8 weeks from screening to follow-up visit.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in the Diffusing Capacity of the Lung for Carbon Monoxide (DLco) on Pulmonary Gas Transfer (Site: Mayo)

    DLco is a measure of the ability of a gas to transfer from alveoli across the alveolar epithelium and capillary endothelium to the red blood cells. Changes in DLco reflect the alveolar-capillary membrane conductance. Acute pulmonary congestion causes a reduction in DLco. In participants with heart failure, decrease in DLco serves as a predictor of disease progression. An impairment in the diffusing capacity of the lung may be related to symptoms and exercise intolerance associated with heart failure. DLco was measured just prior to and after the 3- minute step test on Days -1, and 7 and just prior to and after an intravenous saline infusion on Day 5. Day -1 was Baseline and change from Baseline was calculated from Day -1 pre-exercise of the respective period, except when calculating the post-infusion change from Baseline, where the pre-infusion value was used as Baseline. Data of DLco (milliliter per millimeter of mercury per minute [mL/mmHg/min]) for Mayo site is presented.

    Measured: Baseline, Day 4, Day 5 and Day 7 of each treatment period

  2. Change From Baseline in the Diffusing Capacity of the Lung for DLco on Pulmonary Gas Transfer (Site: Hennepin)

    DLco is a measure of the ability of a gas to transfer from the alveoli across the alveolar epithelium and the capillary endothelium to the red blood cells. Changes in DLco reflect the alveolar-capillary membrane conductance. Acute pulmonary congestion cause a reduction in DLco. In participants with heart failure, decrease in DLco serves as a predictor of disease progression. An impairment in the diffusing capacity of the lung may be related to the symptoms and exercise intolerance associated with heart failure. DLco was measured just prior to and after the 3- minute step test on Days -1, and 7 and just prior to and after an intravenous saline infusion on Day 5. Day -1 was Baseline and change from Baseline was calculated from Day -1 Pre-Exercise of the respective period, except when calculating the post-infusion change from Baseline, where the pre-infusion value was used as the Baseline.

Secondary outcomes (36)

  1. Change From Baseline in Diffusing Capacity of the Lung for Nitric Oxide (DLno) and Membrane Conductance (DM)

    DLno is a measure of the ability of a gas to transfer from the alveoli across the alveolar epithelium and the capillary endothelium to the red blood cells. Changes in DLco reflect the alveolar-capillary DM.

  5. Change From Baseline in the Ventilation/Volume of Carbon Dioxide Production (VE/VCO2) Ratio

    Participants were asked to participate in a submaximal exercise test that consisted of 3 parts: a 2-minute (min) resting Baseline, a 3-min step exercise and a 1-min recovery period. Throughout the test, breathing pattern, gas exchange, and heart rate were monitored using a simplified gas analysis system. Respiratory exchange ratio and the Borg Rating of Perceived Exertion measures were utilized to ensure participants perform progressive exercise while maintaining a submaximal level throughout the exercise period. Minute ventilation, breath frequency, tidal volume, oxygen consumption, carbon dioxide (CO2) production, Respiratory exchange ratio (RER) and end tidal CO2 were obtained from the breath-by-breath gas measurements. The VE/VCO2 slope and other variables were derived from this data. Day -1 was Baseline and change from Baseline was calculated by subtracting the Baseline value from value at specified time point.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing GSK2798745 in people with Heart Failure, run by GlaxoSmithKline at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Sep 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in the Diffusing Capacity of the Lung for Carbon Monoxide (DLco) on Pulmonary Gas Transfer (Site: Mayo) (time frame: Baseline, Day 4, Day 5 and Day 7 of each treatment period). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02497937.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Sep 2018.
