Aquamin for preventing pouch inflammation in UC patients with a J-pouch

Official title: Aquamin® for Prevention of Ulcerative Colitis J-Pouch-associate Intestinal Inflammation

Run by University of Michigan · NCT07501078 · Data updated 2026-11-12

A Phase 2 study tests whether Aquamin®, a natural mineral supplement, can reduce inflammation and protect the gut lining in people with ulcerative colitis who have a J-pouch after ileal pouch-anal anastomosis.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with ulcerative colitis who recently had an IPAA with a J-pouch, able to consent, not pregnant, and able to use contraception or meet protocol requirements.

Probably not a fit

Patients who are pregnant, actively have Crohn's disease, or who cannot comply with study procedures may not benefit and could be excluded from the intervention.

What this trial studies

This Phase 2 interventional trial will evaluate the safety and potential anti-inflammatory effects of Aquamin® in UC patients with a J-pouch. Eligible participants have undergone IPAA surgery within the last nine months and may not be pregnant; premenopausal women must use contraception. The study uses Aquamin® versus placebo to see if it lowers pouch-related inflammation and supports mucosal health. Key measures include inflammation markers and gut lining integrity, along with regular surveys and sample collection. The trial is conducted at the University of Michigan with collaboration from the Crohn's & Colitis Foundation.

Why it matters

Potential benefit: If successful, Aquamin® could offer a new approach to preventing pouchitis and improving long-term gut health for people with a J-pouch.

How similar studies have gone: Prior research in similar mineral-based approaches has shown mixed results; this trial explores Aquamin® specifically for J-pouch inflammation, making findings important for this niche.

* History or diagnosis of any gastrointestinal malignancy
* Kidney disease, including kidney "stones" or hypercalcemia. acute renal failure (past 12 weeks). (Note: A doubtful stone passed in the urine more than three years ago is not considered evidence of current renal stone disease.)

* Participants will be excluded if they have used any of the following within the past 30 days or are unwilling to withdraw for 30 days prior to entering into the study:

  * Calcium, Magnesium, including multivitamins that have low amounts of Calcium/Magnesium and fiber supplements. (Multivitamins without any minerals are allowed).
  * Non-steroidal anti-inflammatory medications (NSAIDs), such as Naproxen or Ibuprofen (except for occasional pain control or low dose aspirin for cardiovascular disease prevention) per protocol.
  * Oral or rectal Corticosteroids (a type of steroid drug such as prednisone or cortisol that helps the body to regulate stress response, immune response and inflammation) and antibiotics (except these can be used briefly during a flare-up once the study treatment has begun after the subject enrolled, if prescribed by the personal physician). Inhaled and skin corticosteroids preparations are ok and not an exclusion criteria.
