Active clinical trials for "Polyps"

This is a multi-center, randomized, double blind, placebo-controlled study to evaluate the efficacy, safety, PK, PD and immumogenicity of CM310 in comparison to placebo in addition to a background treatment of mometasone furcate nasal spray (MFNS) in patients with chronic rhinosinusitis with nasal polyposis (CRSwNP).

The purpose of this study is to evaluate the impact of implementing an integrated clinical care pathway for the diagnosis, referral, evaluation and treatment of large complex colorectal polyps on clinical outcomes

Bleeding is the most common complication associated with polypectomy of large pedunculated colonic polyp. Although several techniques have been developed to minimize bleeding, none of these methods has become the gold standard. To prevent post-polypectomy bleeding effectively, the investigators developed and attempted a new endoscopic technique for removal of large long-stalked pedunculated colonic polyps using band ligations. This study aims to evaluate the safety and efficacy of a novel technique using endoscopic band ligation for removal of long-stalked pedunculated colon polyps.

This is a Phase 4, open-label, single-arm, multicenter study to evaluate the efficacy and safety of dupilumab subcutaneous (SC) injection monotherapy in Japanese participants aged 18 or older with CRSwNP that is not adequately controlled with existing therapies. Duration of study period (per participant): Screening Period (2 to 4 weeks) Intervention Period (up to 52 weeks±3 days)

Cold snare polypectomy (CSP) is now common practice and has proven to be a safe and effective technique for removal of diminutive polyps. Both thick and thin wire snares are now commonly used for CSP. However, because of their physical characteristics, thick wire snares might leave a higher percentage of residual adenoma at the resection site. Since this may result in a higher risk of recurrence, the technique needs to be optimized. Experts have suggested that a thin wire snare might be more efficient, with a lower risk of residual adenoma at the resection site and consequently a lower risk of recurrence and interval cancer.

The purpose of this study is to evaluate safety, tolerability, pharmacokinetics, and pharmacodynamics of PF-06817024 in healthy volunteers, in participants with chronic rhinosinusitis, with nasal polyps and in participants with moderate-to-severe Atopic Dermatitis

Colorectal cancer accounted for 142,570 new cancer cases and 51,370 cancer deaths in USA in 2010 and worldwide has become the third most common cancer and second leading cause of cancer related deaths. Colonic adenomatous polyps are known precursors of colorectal cancer and endoscopic removal of the polyps prevents development of colon cancer. Removal of such large polyps requires special endoscopic techniques-endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), which are more technically difficult to perform, labor intensive, time consuming and carries higher risks of complications (bleeding, perforations, etc.). The purpose of this study is to determine the effectiveness and safety of the LumenR Retractor in performing EMR and ESD. It is hypothesized that the use of this modified colonic overtube will simplify colonoscopic removal of difficult polyps, decrease the time needed to complete the procedure and decrease the rate of complications post endoscopic removal of large and flat colonic.

The purpose of this study is to demonstrate safety and effectiveness of the MyoSure Tissue Removal System when used by community gynecologists in an office setting for the treatment of patients with symptomatic intrauterine polyps and submucosal fibroids.

Outpatient polyp treatment can be performed in a few different ways but generally involves passing a special type of hysteroscope (3-6 millimetre in diameter) into the womb through which specifically designed miniature operating instruments are passed to remove the polyp(s). At present the most commonly used instruments use an electrical cutting edge. However, a new instrument using a mechanical cutting edge has come to market. In patients having a general anaesthesia the mechanical cutting instrument has been shown to be easier to learn, more effective at completely removing polyps and quicker. However, the instrument is slightly larger, which could potentially cause more discomfort and prolong the procedure in the outpatient setting. Therefore, the investigators want to compare the electrical and mechanical instruments for speed, completeness of polyp removal and patient acceptability.

The investigators have recently become proficient in a new, and we believe more effective technique for polyp removal. Known as Endoscopic Submucosal Dissection (ESD). ESD involves removing the polyp in one piece. It is preferable to remove the polyp in one piece as it minimises the chance of leaving residual polyp tissue behind. There have also been recent studies overseas that have shown this new technique to be quite effective. In this study, half of the patients will receive the newly developed technique of polyp removal (ESD), while the other half will receive conventional Endoscopic Mucosal Resection (EMR) treatment. This study will allow us to show which technique results in lower recurrence rates and is more effective.
