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 Results may not be published yet.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.

Summary

This study is testing whether a fecal immunochemical test (FIT), which checks for blood in the stool, can accurately detect colorectal cancer in people with Lynch Syndrome. Lynch Syndrome increases the risk of colorectal cancer, and patients currently need regular colonoscopies. The study will compare FIT results to colonoscopy findings in 400 participants to see how well the simpler 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
Fecal immunochemical test (FIT)
What this could lead to
If successful, this could offer a less invasive, more convenient screening option for people with Lynch Syndrome, potentially reducing the need for frequent colonoscopies.
What could go wrong
This is an early-stage study focused on accuracy, not treatment. FIT may miss some cancers that colonoscopy would find, and results may not apply to all Lynch Syndrome patients.

Inclusion Criteria: * Have a diagnosis of LS with a confirmed pathogenic variant in MLH1, MSH2, MSH6, PMS2 or EPCAM genes. * Aged 20 - 80 years (for those with pathogenic variants in MLH1, MSH2, and EPCAM) * Aged 30 - 80 years (for those with pathogenic variants in PMS2 or MSH6). * Have an upcoming standard of care (SOC) colonoscopy appointment in line with standard LS surveillance guidelines (NCCN). * Patients with previous colon surgery who still have 20cm or more of colon remaining * Patients who are diagnosed with advanced neoplasia (e.g., advanced adenomas or cancers) and have NOT had endoscopic or surgical resection * Willing to sign informed consent, collect stools samples and complete surveys Exclusion Criteria: * Individuals who have not proceeded with genetic testing and therefore are not known to have LS, despite family history and/or criteria for testing. * Individuals who have previously undergone a subtotal or total colectomy. * Newly diagnosed Lynch Syndrome patients \< 20 years old with a pathogenic variant in MLH1, MSH2 or EPCAM, MSH6 or PMS2. * Newly diagnosed Lynch Syndrome patients \< 30 years old with a pathogenic variant in MSH6 or PMS2. * Individuals who are pregnant. * Individuals with inflammatory bowel disease or active malignancy. * Individuals not willing or able to sign informed consent.
