About this study

Official title: The Effects of Non-steroidal Anti-inflammatory Drugs on Circulating Markers of Bone Metabolism Following Plyometric Exercise in Humans

The purpose of this study is to determine the effects of a single dose of non-steroidal anti-inflammatory drugs on post-exercise markers of bone and muscle metabolism.

Read the detailed description

This protocol intends to determine how consuming a single dose of a non-steroidal anti-inflammatory drug (NSAID) affects circulating bone metabolism biomarkers and markers of damage skeletal muscle in response to a bout of plyometric exercise. This will be accomplished using a four trial, placebo-controlled crossover design with trials examining ibuprofen, celecoxib, flurbiprofen and placebo. These particular NSAIDs were chosen because of their widespread use in military populations and differing molecular mechanisms, which could cause differing effects on bone and muscle. Two hours after of consuming a single dose of an NSAID, participants will perform 10 sets of 10 plyometric jumps to induce a mechanical loading stimulus the bone and muscle tissues. Blood, urine, and muscle biopsy samples will be collected before and up to four hours after exercise. Biomarkers representing bone and muscle metabolism will determine the magnitude of adaptive responses to plyometric exercise while using NSAIDs.

Being tested
Ibuprofen 800 mg, Celecoxib 200mg, Flurbiprofen 100 mg, Placebo
Medical subject headings

What is being measured

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

  1. Change from baseline circulating marker of bone formation

    Concentration (pg/mL) of serum N-terminal propeptide of type 1 collagen (P1NP)

    Measured: Change from pre-exercise to 4 hours post-exercise

Secondary outcomes (2)
  1. Change from baseline circulating marker of bone resorption

    Concentration (pg/mL) of serum C-terminal propeptide of type I collagen (CTX)

    Measured: Change from pre-exercise to 4 hours post-exercise

  2. Markers of muscle inflammation

    Interlukin-6 (IL-6), Interlukin-10 (IL-10), and tissue necrosis factor (TNF-a) messenger ribonucleic acid (mRNA) concentration in muscle biopsy tissue

    Measured: Change from pre-exercise to 3 hours post-exercise

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 4 inclusion and 13 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 29 Nov 2023. 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 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. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

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?

Change from baseline circulating marker of bone formation (time frame: Change from pre-exercise to 4 hours post-exercise). 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 NCT05512013, which also lists 6 linked publications.

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 29 Nov 2023.
