T Cells study: Naproxen vs Aspirin
Official title A Phase IIa Randomized, Double-Blinded Clinical Trial of Naproxen or Aspirin for Cancer Immune Interception in Lynch Syndrome
ClinicalTrials.gov ID: NCT05411718
What this study is testing
What is Naproxen?
An investigational oral medication being studied for its effects on immune cells in people with Lynch Syndrome.
Also referred to as Naproxen.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study aims to learn how naproxen and aspirin influence the normal colon in individuals with Lynch syndrome.
- Who it's for
- The study looks for people who have Lynch syndrome.
- What's involved
- Participants will be randomly assigned to take either naproxen or aspirin in a double‑blind manner, with scheduled visits and tests to monitor the colon.
- Phase 2: a mid-size study of how well it works
- Which group you join is decided by chance.
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.

- Participants must not have evidence of active/recurrent malignant disease for 6 months.
- Participants must be at least 6 months from any prior cancer-directed treatment (such as surgical resection, chemotherapy, immunotherapy, hormonal therapy or radiation).
- Participants must have endoscopically accessible distal colon and/or rectal mucosa (i.e., partici-pants must have at least part of the descending/sigmoid colon and/or rectum intact).

- Participants must consent to refrain from using aspirin or NSAIDs or COX-inhibitors for the du-ration of the trial
- Age ≥18 years. Because no dosing or adverse event data are currently available on the long-term use of naproxen or aspirin in patients \<18 years of age, children are excluded from this study but will be eligible for...
