NCT ID NCT07598747

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study is testing a new blood test that looks for DNA from cancer cells. The goal is to see if an artificial intelligence program can accurately detect many different types of cancer at an early stage. The study will include 6,000 adults, some with cancer and some healthy volunteers, to see how well the test works.

What this could mean

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

Active substance
blood test (circulating DNA analysis with artificial intelligence)
What this could lead to
If successful, this could lead to a simple blood test that catches many types of cancer early, when they are easier to treat.
What could go wrong
This is an early-stage study focused on developing and validating the test. It is not yet proven to work in the real world, and there is a risk of false positives or false negatives.

Inclusion Criteria: 1. Adults aged 19 years or older 2. Individuals who understand the study and voluntarily provide informed consent. 3. (only for cancer participants) Participants with newly diagnosed solid tumors (Stage I-IV, including brain tumors) or hematologic malignancies who: * Have a histologically confirmed diagnosis (including bone marrow biopsy), or * Are highly suspected of having cancer based on clinical and/or radiologic evaluation and are scheduled for surgical resection after blood collection; and * Have not yet initiated any treatment (chemotherapy, targeted therapy, hormonal therapy, immunotherapy, radiotherapy, surgical resection, etc.). 4. (only for non-cancer participants) Individuals with no prior history of cancer. 5. (only for non-cancer participants) Individuals scheduled to undergo chest and/or abdominal CT or MRI imaging. Exclusion Criteria: 1. Pregnancy (self-reported pregnancy status). 2. Individuals for whom blood collection is deemed difficult by the investigator. 3. Individuals with a history of infection with HIV, HTLV, or syphilis. 4. (only for non-cancer participants) Individuals diagnosed with another malignancy within the past 5 years (exceptions: non-melanoma skin cancer, in-situ malignancies, thyroid cancer, and cervical intraepithelial neoplasia treated with curative intent). 5. (only for non-cancer participants) Individuals with cancer of unknown primary origin. 6. (only for non-cancer participants) Individuals with synchronous or metachronous multiple primary cancers.
