NCT ID: NCT00927485 Completed - Clinical trials for Familial Adenomatous Polyposis

Use of Curcumin for Treatment of Intestinal Adenomas in Familial Adenomatous Polyposis (FAP)

Start date: November 2007
Phase: N/A
Study type: Interventional

Familial Adenomatous Polyposis (FAP) is an autosomal dominant disorder characterized by the formation of multiple adenomatous colorectal polyps usually in the teenage years. Virtually, all patients with FAP will develop colorectal cancer on average by the 5th decade of life if prophylactic surgery is not performed. Besides, these individuals must have lifelong cancer surveillance of the remaining colorectum or ileum. Use of nonsteroidal anti-inflammatory drug (NSAID), such as sulindac, or celecoxib, which selectively inhibits prostaglandin synthesis primarily via the inhibition of cyclogenase-2 (COX-2) have been shown to reduce the incidence and induce regression of adenomas in the rectum of patients with FAP. However, use of NSAIDs and COX-2 inhibitors is associated with significant comorbidity including renal and gastric toxicity and increased risk of vascular events. Therefore, identification of a chemopreventive agent that would have similar efficacy but less toxicity would enhance our ability to treat these patients. Therefore the following specific aim has been proposed:To determine in a randomized, double-blinded, placebo-controlled study the tolerability and efficacy of curcumin to regress intestinal adenomas by measuring duodenal and colorectal/ileal polyp number, and polyp size in patients with FAP.

NCT ID: NCT00808743 Completed - Clinical trials for Familial Adenomatous Polyposis

Prevention of Progression of Duodenal Adenomas in Patients With Familial Adenomatous Polyposis

PreDuoFAP
Start date: May 2009
Phase: Phase 2/Phase 3
Study type: Interventional

Duodenal carcinomas are the leading cause of mortality in patients with Familial Adenomatous Polyposis (FAP) who underwent prophylactic colorectal surgery. The purpose of this study is to determine wether celecoxib combined with ursodeoxycholic acid is an effective chemoprevention strategy to influence the progression of duodenal adenomas to carcinomas in patients with FAP.

NCT ID: NCT00770991 Completed - Clinical trials for Familial Adenomatous Polyposis

Lyophilized Black Raspberries in Adults With Familial Adenomatous Polyposis (FAP)

Start date: December 2005
Phase: Phase 1
Study type: Interventional

This is a 36 week dietary intervention pilot study to evaluate the effects of lyophilized black raspberries on rectal polyp burden and biomarkers in subjects with FAP. Subjects will undergo a colonoscopy or sigmoidoscopy before study treatment to determine eligibility for the study. Eligible participants will undergo a sigmoidoscopy at 36 weeks after the initiation of study treatment. The size and number of rectal polyps will be documented on a code sheet and by photograph. The efficacy outcome will include the percentage reduction in the number of rectal polyps between baseline and 36 weeks.

NCT ID: NCT00685568 Completed - Colorectal Cancer Clinical Trials

Celecoxib in Preventing Colorectal Cancer in Young Patients With a Genetic Predisposition for Familial Adenomatous Polyposis

Start date: November 21, 2002
Phase: Phase 1
Study type: Interventional

RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. The use of celecoxib may keep polyps and colorectal cancer from forming in patients with familial adenomatous polyposis. PURPOSE: This randomized phase I trial is studying the side effects and best dose of celecoxib in treating young patients with a genetic predisposition for familial adenomatous polyposis.

NCT ID: NCT00641147 Completed - Clinical trials for Familial Adenomatous Polyposis

Curcumin in Treating Patients With Familial Adenomatous Polyposis

Start date: October 2010
Phase: Phase 2
Study type: Interventional

This randomized phase II trial studies curcumin in treating patients with familial adenomatous polyposis. Curcumin may prevent colorectal cancer in patients with a history of rectal polyps or colorectal neoplasia.

NCT ID: NCT00525655 Completed - Colorectal Cancer Clinical Trials

Multimedia Intervention in Patients With Familial Adenomatous Polyposis (FAP)

Start date: August 2007
Phase: N/A
Study type: Interventional

The goal of this research study is to test the first version of a website that will offer information and support for adolescents and young adults with FAP. Researchers want to see if the website will be helpful, easy to understand, and easy to use for young patients with FAP.

NCT ID: NCT00510692 Completed - FAP Clinical Trials

Chemoprevention Trial in Familial Adenomatous Polyposis (FAP) Coli Using EPA

Start date: November 2006
Phase: Phase 2/Phase 3
Study type: Interventional

This purpose of this study is to investigate whether the number and size of rectal polyps can be reduced in patients with Familial Adenomatous Polyposis (FAP) by using a highly-purified form of a naturally occurring substance, the omega-3 fatty acid, eicosapentaenoic acid (EPA).

NCT ID: NCT00503035 Completed - Clinical trials for Familial Adenomatous Polyposis

Molecular Targeting of 15-Lipoxygenase-1 (15-LOX-1) for Apoptosis Induction in Human Colorectal Cancers

Start date: August 20, 2003
Phase: Phase 2
Study type: Interventional

Primary Objective: - To determine whether celecoxib downregulates GATA-6 expression to upregulate 15-LOX-1 expression and induce apoptosis in human rectal tumors, researchers will measure GATA-6 and 15-LOX-1 expression, 13-S-HODE levels, and apoptosis rates in normal and colorectal polyp epithelial tissues before and after 6 months of celecoxib treatment of patients with familial adenomatous polyposis (FAP).

NCT ID: NCT00033371 Completed - Colorectal Cancer Clinical Trials

Celecoxib With or Without Eflornithine in Preventing Colorectal Cancer in Patients With Familial Adenomatous Polyposis

Start date: December 13, 2001
Phase: Phase 2
Study type: Interventional

This randomized phase II trial studies how well giving celecoxib with or without eflornithine works in preventing colorectal cancer in patients with familial adenomatous polyposis. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of celecoxib and eflornithine may keep cancer from forming in patients with familial adenomatous polyposis.
