About this study

This is a single-center, non-randomized, open-label, single-arm pilot study investigating the systemic immune response to histotripsy in patients with colorectal cancer with liver metastasis. Histotripsy is an FDA-approved, non-invasive therapeutic modality for the treatment of liver tumors, including both primary and metastatic lesions. In this study, investigators aim to evaluate the kinetics of peripheral T-cell response following histotripsy of colorectal cancer liver metastases (CRCLM). Given the well-documented immune-tolerant tumor microenvironment of liver metastases and their role in systemic resistance to checkpoint inhibitors, investigators hypothesize that histotripsy-induced tumor disruption will lead to measurable alterations in peripheral T-cell clonal expansion and exhaustion markers. Investigators will assess these changes via serial blood draws before and after histotripsy, with the goal of characterizing the systemic immune impact of local tumor ablation. Findings from this study may inform future combination strategies integrating histotripsy with immunotherapy to enhance treatment response in microsatellite-stable CRC

What is being measured

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

  1. Measure of System Immune Modulation via T-cells

    To evaluate whether histotripsy of CRCLM induces systemic immune modulation, as measured by changes in peripheral T-cell clonal expansion and markers of T-cell exhaustion.

    Change in peripheral T-cell clonal expansion measured in the week prior to histotripsy, directly after histotripsy, and at 14, 28, and 90 days following histotripsy.

    Change in markers of T-cell exhaustion measured in the week prior to histotripsy, directly after histotripsy, and at 14, 28, and 90 days following histotripsy.

    Measured: 2 years

Secondary outcomes (1)
  1. Assess the Kinetics of Peripheral Immune Cell Response via T-cells

    Change in the kinetics of T-cell clonal expansion measured at the week prior to histotripsy, directly after histotripsy, and at 14, 28, and 90 days following histotripsy via blood samples will be analyzed using statistical analysis.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Histotripsy in people with Colorectal (Colon or Rectal) Cancer, run by Northwell Health 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 19 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: looking for participants now, as of the sponsor's last update on 22 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.

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?

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?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Measure of System Immune Modulation via T-cells (time frame: 2 years). 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 22 Jan 2026.
