Aspirin or naproxen to prevent cancer in Lynch syndrome

T CellsColorectal CancerLynch Syndrome

Treatments studied

Part of Cancer, Digestive system, Genetic & congenital, Hormones & metabolism clinical trials.

This trial tests whether daily aspirin or naproxen can “intercept” (stop) cancer from starting or coming back in people with Lynch syndrome who are currently cancer-free. Participants are randomly assigned to one of the two drugs, and neither the participant nor the team knows which one you’re taking.

Summary written for real people, not researchers, by Clin2.

Who can take part

  • You must have Lynch syndrome confirmed by genetic testing, or by specific tumor/test findings
  • You must be cancer-free or without active/recurrent cancer for at least 6 months
  • You must be at least 6 months away from any cancer treatment like surgery, chemo, radiation, or immunotherapy
  • You need bowel anatomy that can be checked with colonoscopy or sigmoidoscopy (part of the left colon or rectum must still be there)
  • You must agree to stop using aspirin/NSAIDs/COX-inhibitors during the study (with special rules if you take low-dose daily aspirin for heart protection)
  • You must be able to do two lower-bowel endoscopy visits with biopsies, about 12 months apart, plus yearly screening for the study

Mesalamine to help prevent colon cancer in Lynch syndrome

This trial tests whether mesalamine, a medicine used for bowel inflammation, can help prevent colorectal cancer in people with Lynch syndrome who do not currently have cancer. It may help by lowering the chance that new pre-cancer growths form over time.

Preventing cancer in Lynch syndrome carriers with dendritic cell vaccine

This trial tests whether a personalized vaccine made from your own immune cells can help prevent cancer in people with Lynch syndrome. You must have no history of cancer and be willing to have regular colonoscopies.

Vaccine trial to prevent cancer in Lynch syndrome

This trial tests a preventive vaccine for people with Lynch syndrome. It aims to train your immune system to recognize and stop cancer before it starts. The vaccine is made from your own immune cells (dendritic cells).

Lynch syndrome and gut immune system study

This study looks at how the immune system interacts with the gut lining in people with Lynch syndrome and those without. It may help us better understand how Lynch syndrome affects the body.

Testing blood and stool for colon cancer in Lynch syndrome

This study collects blood and stool samples to see how well they can detect colorectal cancer or advanced growths in people with Lynch syndrome (an inherited colon cancer risk) or suspected Lynch syndrome. It may help find cancer or precancer earlier, which can improve next-step decisions.

NCT07609901Not yet recruiting· Phase 3
Vaccine Study for Lynch Syndrome Prevention

This study tests whether a new vaccine made from dendritic cells (immune cells) can help prevent cancer in people with Lynch syndrome, a genetic condition that increases cancer risk. The vaccine is designed to train your immune system to catch and destroy precancerous cells before they become cancer.
