Active clinical trials for "Polyps"

The purpose of this study is to determine the efficacy and safety of omalizumab compared with placebo in adult participants with chronic rhinosinusitis with nasal polyps (CRSwNP) who have had an inadequate response to standard-of-care treatments. Study GA39855 (POLYP 2; NCT03280537) was another Phase III study by the Sponsor with identical objectives and design and was run in parallel with this study.

This study will evaluate the effectiveness and safety of MFNS in improving nasal congestion/obstruction and in reducing bilateral nasal polyps.

The purpose of this study is to find out if guided fluid administration with the esophageal monitor is superior to standard fluid administration and whether use of the hetastarch or lactated ringers offers different benefits with respect to length of stay in the hospital after hand-assisted colorectal surgery.

The aim of these studies is to study the natural history, the symptoms of, as well as the effect of hysteroscopic resection of endometrial polyps. Furthermore, another aim is to study new diagnostic techniques to differentiate between malignant and benign endometrial polyps.

Complete polypectomy is one of the major factors for effectiveness of colonoscopy to prevent colon cancer. Given the prevalence of the 4-6 mm polyp, and the concern about interval cancers at polypectomy sites, there is a clear and significant need to determine which technique(s) are most appropriate for clinical practice. This study was to compare the three commonly used polypectomy techniques in terms of efficacy and efficiency.

This is an open-label, multicenter study designed to assess the safety of intranasal administration of 400 μg of fluticasone propionate twice a day delivered by the OptiNose device in subjects with chronic sinusitis with or without nasal polyps. The study consists of an up-to-7-day pretreatment phase followed a 12-month open-label treatment phase. The duration of each subject's participation is approximately 53 weeks.

Phase 2, open-label, multi-center study to evaluate the clinical effects of oral administration of dexpramipexole for 6 months in subjects with chronic sinusitis with nasal polyps and eosinophilia.

Colorectal cancer is a major cause of morbidity and mortality in Western countries. Scientific studies have shown that endoscopic polypectomy is efficacious in preventing CRC incidence and mortality. Endoscopic polypectomy carries a risk of major complications, such as bleeding or bowel perforation, so that a careful balance between efficacy and safety appears to be clinically relevant. Most of the polypectomies are performed for diminutive (<5 mm) or small (6-9 mm) lesions, which represent over 90% of all the polyps. To minimize the risk of complications when removing <10 mm polyps, cold-polypectomy techniques - i.e. without electric current - by means of biopsy forceps or snare, have been proposed. Although the risk of perforation is virtually excluded by cold-polypectomy, the lack of electrocautery may result in an increased risk of bleeding. The safety of cold-snare polypectomy has however been recently shown in controlled trials. Regarding the efficacy of cold-polypectomy for subcentimetric polyps, very few studies have assessed the post-polypectomy completeness of the removal of polyp tissue (i.e. residual disease), and no studies have compared it to conventional polypectomy. The investigators perform this study to assess both the efficacy and safety of a novel snare (Exacto™) for polyp removal.

The use of an exclusive cold polypectomy snare enables a clean cut of diminutive colorectal polyps, resulting in an increase in the complete resection rate and a decrease in the adverse events.

Colorectal cancer is the second most common cancer in the world and the second leading cause of cancer-related mortality. Colorectal cancers arise from precursor adenomatous polyps in a well characterized adenoma to carcinoma progression. The removal of such precursor lesions reduces colorectal cancer mortality between 30 to 50%. Colonoscopy is used for detection of neoplastic polyps but significant miss rates of such lesions are reported. Methods to reduce spasm of the colon have been investigated to increase adenoma detection rates including the use of warm water irrigation and hyoscine butyl bromide. Carbon dioxide warmed to body temperature is postulated to have spasmolytic effects. Administration of warmed carbon dioxide during colonoscopy may improve polyp detection. Objective: In this study, colonoscopy using warmed carbon dioxide insufflation will be compared to standard room temperature air insufflation to see if there is a greater detection of polyps per patient. Methods: Patients undergoing colonoscopy for screening and surveillance indications will be included and randomized to receive either room temperature room air or warmed carbon dioxide (37 degrees Celsius). Endoscopists and patients will be blinded to the intervention. Data on indication, preparation, sedation, withdrawal time will be recorded. Polyp detection rate will be the primary outcome. Secondary outcomes will include adenoma detection rate and advanced lesion detection rates.
