What is being measured

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

  1. Serum concentration of TWEAK at day 1

    Measured: Day 1

Secondary outcomes (4)
  1. Relative expression levels of TWEAK mRNA in muscle biopsy at day 1

    Measured: Day 1

  2. Relative expression levels of Fn14 mRNA in muscle biopsy at day 1

    Measured: Day 1

  3. Correlation between serum TWEAK levels and muscle strength

    Measured: Day 1

  4. Incidence of AEs and SAEs

    Measured: Screening through Day 14

Questions about this trial

What is this clinical trial studying?

An observational study of Sarcopenia, run by University of Florida at 1 site 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 15 inclusion and 12 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 11 Apr 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 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.

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?

Serum concentration of TWEAK at day 1 (time frame: Day 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 11 Apr 2019.
