About this study

Official title: Pilot Study to Evaluate the Feasibility of Measuring (a) Intratumoral Pressures Using a Novel Piezo- Resistive Semiconductor Catheter and (b) Intratumoral Stiffness Using Shear Wave Elastography With Ultrasound

This trial studies how well a Millar Mikro-tip catheter and shear wave elastography measure pressure and stiffness inside tumors among patients with solid tumors undergoing an ultrasound-guided biopsy. A Millar Mikro-tip catheter measures the pressure inside the tumor. Shear wave elastography is similar to an ultrasound and uses sound waves to vibrate the tissue in order to study tissue stiffness. These measurements may help doctors learn if pressure and stiffness are related to intratumoral fibrosis (the thickening and scarring of connective tissue).

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the feasibility of measuring tumor intratumoral pressures in vivo using a commercially available, sterile, single use, cardiovascular catheter device.

II. To determine the feasibility of measuring tumor intratumoral stiffness in vivo using a commercially available shear wave elastography with ultrasound.

SECONDARY OBJECTIVES:

  1. To assess the relationship of tumor pressure, stiffness, and fibrosis.

OUTLINE:

Patients scheduled for an ultrasound-guided tumor biopsy undergo stiffness assessment of the tumor with shear wave elastography over 2 minutes and pressure measurements of the tumor using a Millar Mikro-tip catheter before and after the biopsy is collected.

After completion of the study, patients are followed up at 24-48 hours and at 30 days.

Device Feasibility (Millar Mikro-tip catheter, elastography)ExperimentalPatients scheduled for an ultrasound-guided tumor biopsy undergo stiffness assessment of the tumor with shear wave elastography over 2 minutes and pressure measurements of the tumor using a Millar Mikro-tip catheter before and after the biopsy is collected.
Receives: Device: Shear Wave Elastography; Procedure: Tumor Interstitial Fluid Pressure Measurement

What is being measured

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

  1. The change in Tumor pressure

    Measured by Millar Microcath (Millar Mikro-Tip Pressure Catheter). Tumor pressure and its change will be summarized using mean, standard deviation, and range by time point.

    Measured: Up to 30 days

  2. The change in Tumor stiffness

    Measured by General Electric LOGIQ Shear Wave Elastography. Tumor stiffness and its change will be summarized using mean, standard deviation, and range by time point.

    Measured: Up to 30 days

Secondary outcomes (1)
  1. Tumor pressure

    As a secondary endpoint, the relationship of tumor pressure with tumor fibrosis will be assessed for each patient. An ordinary least squares regression will be fit to the data to investigate the potential relationship between tumor stiffness, pressure, and fibrosis.

    Measured: Up to 30 days

Questions about this trial

What is this clinical trial studying?

A study testing Shear Wave Elastography and Tumor Interstitial Fluid Pressure Measurement in people with Solid Neoplasm, run by M.D. Anderson Cancer Center 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 2 inclusion and 3 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 13 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 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?

The change in Tumor pressure (time frame: Up to 30 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 13 Jan 2026.
