April 30, 2026 updated by: Eric Grogan, Vanderbilt-Ingram Cancer Center

A Combined Biomarker Model for Risk Stratification of Indeterminate Pulmonary Nodules A Multicenter Prospective Observational Pilot Study

This is a prospective, multicenter observational study aim at estimating the potential clinical utility of the CBM and at establishing the SOPs and protocols for a future randomized control trial.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Objectives:

  • To obtain the combined biomarker model (hs-CYFRA 21-1, radiomics, Mayo) score in a prospective observational trial and estimate potential clinical utility compared to the Mayo Model.
  • To establish standard operating procedures (SOPs) and protocols in a prospective observational trial in anticipation of a future randomized control trial. These include the REDCAP data input protocols, the radiomic protocols, blood draws in the CLIA environment, and estimating the CBM score in a time reasonable for clinical practice (< 2 weeks).

Study Type

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
