What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This pilot study compares two ways of collecting blood to detect circulating tumor DNA (ctDNA) in people with liver or pancreatic cancers. Researchers will take blood from a standard arm vein and also from the vein that drains directly from the tumor during a biopsy. The goal is to see if the tumor-draining vein sample contains more or different tumor DNA. Only 15 participants are being enrolled, so this is an early-stage exploration.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to a more sensitive way to detect tumor DNA, potentially improving cancer monitoring and treatment decisions.
What could go wrong
This is a very small pilot study with only 15 participants, so results may not apply broadly. The procedure is also more invasive than a standard blood draw.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 15 people

The number the study aims to enrol. It can still change while the study runs.

Started

Sep 2022

Expected to finish

Jun 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * 18 years of age or older * Have or are undergoing work-up for hepatobiliary and/or pancreatic carcinoma (such as hepatocellular carcinoma, cholangiocarcinoma, ampullary carcinoma, pancreatic carcinoma) * Scheduled for an image-guided percutaneous or trans-jugular biopsy of a lesion * Must be able to provide a written informed consent Exclusion Criteria: * Patients unable to hold reasonably still on a procedure table or hold their breath during imaging or needle passes * Patients with a gross body weight over 375 pounds (upper limit of the CT and angiography tables) * Patients with uncorrectable coagulopathy * Platelet count \< 30,000/ul * International Normalized (INR) \> 1.5 * Patients with moderate to severe ascites who cannot undergo trans-jugular biopsy or sufficient drainage * No clear reachable target for percutaneous or trans-jugular biopsy * Patient who cannot have a peripheral blood draw for ctDNA
