About this study

Official title: A Multi-Center Observational Study to Validate RNA-Biomarkers as Prognostic of Fracture Healing

The purpose of this study is to test the accuracy of using RNA in blood as a way to forecast new fracture healing outcome.

Read the detailed description

This study will follow a registry + biospecimen collection format. Subjects will be enrolled at participating Sites as they present for care for new traumatic appendicular skeletal fractures (0 - ≤7 Days post-injury) and will provide blood specimens for study analysis and future use at up to 4 post-injury windows of treatment (i.e., Window 1, 0 - ≤7 Days; Window 2, 8 - ≤14 days; Window 3, 15 - ≤42 Days; and Window 4, 43 - ≤84 Days post-injury).

What is being measured

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

  1. Proportion of subjects with correct predicted outcome

    The proportion of Subjects who have a correctly prognosed Fracture Healing Outcome (Normal Healing vs. Delayed Healing vs Nonunion) via RNA in peripheral blood when captured during four specific Windows:

    1. 0 - ≤7 Days post-injury; and/or
    2. 8 - ≤14 days post-injury; and/or
    3. 15 - ≤42 Days post-injury; and/or
    4. 43 - ≤84 Days post-injury as compared to clinically determined outcomes up to 270 Days post-injury.

    Measured: 0 - 270 days

  2. Intra-Patient Correlation

    The intra-patient correlation of RNA-biomarker-driven prognostic calls made by the blinded statistician across windows for those patients who contribute >1 specimen for RNA-biomarker analysis.

    Measured: 0 - 270 days

Questions about this trial

What is this clinical trial studying?

An observational study of Fractures, Bone, run by University of Pennsylvania at 7 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 31 inclusion and 5 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: enrolling by invitation, as of the sponsor's last update on 16 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 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.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

Proportion of subjects with correct predicted outcome (time frame: 0 - 270 days). 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?
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 16 Jan 2026.
