Trial summary

Preliminary evidence suggest that patients with chronic obstructive pulmonary disease (COPD) suffer from lower-limb muscle dysfunction. This may, at least in part, be due to a combination of physical inactivity and muscle oxidative stress. Read more about this study

About this study

Official title: Oral β-Alanine Supplementation in Patients With COPD: Structural, Metabolic and Functional Adaptations

Preliminary evidence suggest that patients with chronic obstructive pulmonary disease (COPD) suffer from lower-limb muscle dysfunction. This may, at least in part, be due to a combination of physical inactivity and muscle oxidative stress. Pilot data (not published) clearly show that patients with COPD have significantly lower carnosine, which is a pH (acidity-basicity level) buffer and antioxidant, levels in the m. vastus lateralis compared to healthy subjects. Beta-alanine supplementation has shown to increase muscle carnosine in trained and untrained healthy subjects. This study will assess if muscle carnosine can be augmented by beta-alanine supplementation in 40 COPD patients (20 patients receive beta-alanine, 20 patients receive placebo). 10 healthy elderly controls will also be assessed to compare baseline muscle carnosine levels.

The aims of this study are to:

  1. Investigate baseline muscle carnosine levels to confirm the pilot data in a larger sample of patients with COPD compared with healthy elderly subjects
  2. Investigate if beta-alanine supplementation augments muscle carnosine in COPD patients and whether it has an influence on exercise capacity, lower-limb muscle function and quality of life
  3. To investigate baseline and post supplementation structural and metabolic muscle characteristics and markers of oxidative stress and inflammation in COPD patients and it's association with muscle carnosine levels

Questions about this trial

What is this clinical trial studying?

A study testing beta-alanine in people with Chronic Obstructive Pulmonary Disease (COPD), run by Hasselt University at 1 site in Belgium.

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 2 inclusion and 8 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 22 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

muscle carnosine (time frame: change from baseline to 12 weeks). The study lists 3 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 NCT02770417, which also lists 1 linked publication.

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 22 Feb 2019.
