NCT ID NCT06304168

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests a new blood and urine test that looks for DNA markers to detect cancer early and identify where it started. Researchers at Mayo Clinic will enroll about 6,150 people, including those with and without cancer. The goal is to see if these tests can accurately find cancer and guide next steps.

Inclusion Criteria: * Aim 1 Tissue * Cases: * Patient has a biopsy confirmed diagnosis of target histology * Tissue samples from synchronous or metachronous primary cancers may be used as long as they are clearly of a different target organ. * Tumors from patients with an underlying genetic disorder pre-disposing to cancer may be included as long as they are stratified from those without * Controls: * Patient does not have the diagnosis of target histology * Aim 2 Blood * Cases: * Patient has a biopsy confirmed diagnosis of target histology or radiographic criteria that are unequivocal for diagnosis (example, meets radiographic criteria for hepatocellular carcinoma) * Controls: * Patient does not have a documented diagnosis of cancer within 1 year following blood collections * Aim 3 Urine * Cases: * Patient has a biopsy confirmed diagnosis of target histology or radiographic criteria that are unequivocal for diagnosis (example, meets radiographic criteria for hepatocellular carcinoma) * Controls: * Patient does not have a diagnosis of the target histology Exclusion Criteria: * Aim 1 Tissue * Cases and Controls: * Patient has had any transplants prior to tissue collection * Patient has received chemotherapy class drugs within 5 years prior to tissue collection * Cases: * Patient has had radiation to the current target lesion prior to tissue collection * Patient has multi-centric/multi-focal breast cancer with differing genetic profiles (ER/HER2/PR status differ; if multiple masses are present and not all are tested then exclude patient) * Patient has bilateral breast cancer/Ductal carcinoma in situ (DCIS) * Aim 2 Blood * Controls: * Patient has known cancer prior to current sample acquisition (not including basal cell or squamous cell skin cancers) (if patient has not been seen or if information is not available, the patient is still eligible) * Cases: * Patient has known cancer outside of the target cancer 5 years prior to blood collection (not including basal cell or squamous cell skin cancers) * Patient has received chemotherapy class drugs in the 5 years prior to blood collection * Patient has had any prior radiation therapy to the target lesion prior to blood collection * Patient has had an intervention to completely remove current target pathology * The current target pathology is a recurrence * Patient has had a biopsy to the target organ and/or lesion within 3 days before blood collection * Aim 3 Urine * Patient has known cancer outside of the target cancer 5 years prior to urine collection (not including basal cell or squamous cell skin cancers) * Patient has received chemotherapy class drugs in the 5 years prior to urine collection * Patient has had any prior radiation therapy to the target lesion prior to urine collection * Patient has had a biopsy to the target organ and/or lesion within 3 days before urine collection * The current target pathology is a recurrence * Patient has chronic indwelling urinary catheter * Patient has had a urinary tract infection within the 14 days prior to sample collection * If patient does not have a primary bladder, ureter or urethral cancer, patient has a history of bladder ureter, or urethral cancer * Cases: * Patient has had an intervention to completely remove current target pathology * The current target pathology is a recurrence
