The purpose of this study is to compare the efficacy of a low-volume bowel preparation versus a high-volume bowel preparation for bowel cleansing on hospitalized patients undergoing colonoscopies.

The primary purpose of this study is to evaluate the safety of the Check-Cap C-Scan System.

The purpose of this study is to compare the effectiveness of Colon Capsule Endoscopy versus Computed Tomographic Colonography for the screening of colon polyps in the usual screening population.

This study first is designed to see what dose of indigo carmine ingested orally mixed with the standard colonoscopy prep is needed to provide adequate staining of the right colon. It then will use this adequate staining concentration of Indigo Carmine to study whether this dye will increase the detection of polyps during colonoscopy.

The primary aim of the study is to compare safety and effectiveness of two methods of endoscopic resection of large colorectal polyps: cold snare EMR (without electrocautery) vs. hot snare EMR (with electrocautery).

The purpose of this research is to evaluate the accuracy of a medical device that has been developed to automatically find polyps (small growths) during colonoscopies. The device uses a computer to detect and highlight potential polyps from the usual video images made during a colonoscopy, and such detections will be visible to  the doctor during the regular colonoscopy procedure. This medical device is called Endoscopy Video Assistance for Colonoscopy (EVA-C). EVA-C, an investigational device, has been developed to assist the doctor in identifying possible polyps, but is not meant to replace their decision making. 

The purpose of this study is to evaluate the safety and effectiveness of CapsoCam® Colon (CV-3) endoscope system for the detection of colonic polyps. It is anticipated that the data from this clinical trial will be used to support marketing authorizations to commercialize the CapsoCam® Colon (CV-3).

The main objective of the study is to determine the ability of the C-Scan system to identify subjects who are at elevated risk for colon polyps. This will be evaluated by comparing the C-Scan data to colonoscopy data. The C-Scan procedure is therefore performed before the colonoscopy procedure, in order to compare these tests and evaluate the C-Scan system's effectiveness. During the C-scan procedure, Subjects will be asked to come for an appointment in a clinic. during this appointment, The C-Scan Track will be attached to the subject's back. Subjects then will be asked to swallow the C-Scan capsule ...

This phase II trial is studying how well giving acetylsalicylic acid together with eflornithine works in treating patients at high risk for colorectal cancer. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of acetylsalicylic acid and eflornithine may prevent colorectal cancer.

The primary purpose of this study is to collect de-identified, clinically-characterized stool and whole blood specimens for use in developing and evaluating the performance of new biomarker assays for the detection of colorectal cancer (CRC).

The purpose of this study is to understand how to improve polyp resection of large polyps, and how to make it as effective and as safe as possible.

The purpose of this study is to assess the effectiveness of SIC 8000 injected into the submucosa under polyps, adenomas, early-stage cancers or other gastrointestinal mucosal lesions to provide a lift to them prior to grasping and cutting with a snare during endoscopic removal procedures.

The purpose is to investigate whether a simple additional treatment applied during colonoscopy (called 'soft' coagulation) can reduce the risk of recurrence of polyp at the area where the polyp was removed. After a large polyp is removed it is known that there is a 20% chance that a small recurrence of polyp occurs at the site of removal can occur within 5 months of the polyp being removed. This in theory will burn off tiny polyp tissue, which is usually not visible to the naked eye. This additional treatment may possibly reduce the risk of polyp recurrence.

The purpose of this study is to confirm the performance of the CB-17-08 software as a medical device (SaMD) to help endoscopist during the colonoscopy procedure to find potential mucosal lesions, including polyps, adenomas and carcinomas, without significant noise disturbing the endoscopist attention, nor negative interference with the lesions detection than with the standard endoscopy video alone. The study will evaluate whether high-definition white-light (HDWL) colonoscopy using CB-17-08 SaMD will have a lower miss rate of clinically significant polyps, as compared to standard HDWL colonoscopy alone (the current standard of care for colonoscopy).

Colorectal cancer is the third most commonly diagnosed cancer in both men and women in the United States (1). Colorectal cancer arises from colonic polyps. The major types of polyps associated with colorectal cancer development are adenomatous (tubular which is most common and other types are villous and tubulovillous) and serrated (hyperplastic, sessile or traditional) polyps with varying degrees of dysplasia (2). Hyperplastic polyps are common but they have a low malignancy potential (3). There is evidence that colonic inflammation plays a major role in colon polyp and colorectal cancer development. For example, inflammatory bowel disease is a major ...

The purpose of this study is to see if advanced endoscopic imaging may be helpful to accurately distinguish pathological tissue from normal tissue and guide therapy of endoscopically identified pathology.

This is a proof-of-concept study to evaluate the preliminary clinical activity of guselkumab in subjects with Familial Adenomatous Polyposis. The study is designed to determine if guselkumab has clinical activity in the colorectum and duodenum, by reducing the number of polyps over a period of 24 weeks.

The purpose of this study is to form processes to get findings from targeted gene sequencing that can be acted on using two common actionable genetic disorders–familial hyperlipidemia and familial colorectal cancer.
