Active clinical trials for "Nasal Polyps"

The aim of this study is to evaluate the effect of the primary endoscopic frontal sinus surgery on the clinical outcome in patients having moderate to severe eosinophilic chronic rhinosinusitis with polyps with primary outcome measures in form of recurrence of polyp using endoscopic polyp score and Secondary outcome measures include Lund MacKay score, SNOT-22 and need for corticosteroid to control polyp postoperatively.

Chronic rhinosinusitis with nasal polyps is a common nasal comorbidity with a wide range of symptoms that might cause severe distress and disabilities for patients. Many patients undergo repeated courses of systemic steroids and are exposed to various adverse effects. many cases finally revert to surgery. Budesonide was safely used as a nasal wash in cases of nasal polyps, our aim to determine If intrapolyp injection is a better method for delivering budesonide.

The purpose of this study is to compare the efficacy and safety of rimegepant versus placebo in the acute treatment of chronic rhinosinusitis (CRS) with and without nasal polyps.

This is a 16-Week Randomized, Double-Blind, Placebo Controlled, Parallel-Group, Multicenter Study Evaluating the Efficacy and Safety of OPN-375 186 μg Twice a Day (BID) in Adolescents with Bilateral Nasal Polyps followed by a 12-Week Open-Label Treatment Phase. The total planned number of subjects is approximately 120 adolescents (12-17 years of age) who will be randomly assigned to receive 1 of 2 study treatments using a 2:1 ratio (OPN-375 186 μg: Placebo). For the PK sub-study, up to 14 subjects will be enrolled to obtain 10 completers.

Functional endoscopic sinus surgery (FESS) is the pimary surgical treatment of CRS, characterized with the preservation of nasal structure and function.But the control of disease by surgery has been unsatisfactory. Recent studies have shown that patients with recurrent CRSwNP (usually with severe eosinophilic inflammation), more radical surgery may be more effective. The purpose of this prospective and randomized study is to determine the effect of endoscopic sinus surgery for extensive mucosal removal in patients with eosinophilic chronic rhinosinusitus with nasal polyps.

The investigators believe that administering Dupilumab during the pre- and peri-operative period of surgery for chronic rhinosinusitis with nasal polyps (CRSwNP) will safely downregulate Type 2 inflammation of the healing sinus environment and will allow for better coordinated and more effective mucosal healing. Specifically, the investigators believe that endoscopic signs and symptoms of recurrence will be reduced in the Dupilumab-treated group, and that this will be reflected in quality of life (QOL). Additionally, by reducing Type 2 inflammation at the time of surgery, Dupilumab may offer an additional benefit by decreasing operative bleeding. The investigators propose to perform a placebo-controlled, prospective, real-world trial in patients with CRSwNP undergoing revision surgery for CRSwNP to verify whether recurrences after endoscopic sinus surgery (ESS) can be prevented by controlling Type 2 inflammation during the peri-operative period using Dupilumab. A series of seven injections of Dupilumab (or placebo) will be administered to symptomatic patients undergoing ESS for CRSwNP. Beginning 4 weeks prior to surgery and continuing for 8 weeks post-surgery, q2 weekly injections will be administered to reduce Type 2 inflammation at time of ESS and during the post-operative recovery period. Principal outcome will be absence of recurrence of mucosal oedema of the sinus cavity as assessed by endoscopy. Secondary objectives will assess Polyp size, sinus symptomatology, quality of life, smell and asthma control. Exploratory analyses will assess microbiome and gene expression profiles to better understand molecular mechanisms implicated in CRSwNP pathophysiology, and to identify the pathways implicated by modulation of Type 2 inflammation.

Chronic Rhinosinusitis (CRS) is a chronic inflammatory condition of the nasal passage and paranasal sinuses that places significant burden on affected patients and global healthcare systems. Current treatments for CRS such as long-term antibiotics, anti-inflammatory drugs, and surgery often reduce symptoms and signs of disease temporarily, however long-term results are much less satisfactory. Recently, the theory of a damaged microbiome (dysbiosis) as a cause or promoting factor behind CRS has gained increasing evidence from the scientific community. A condition of the gut with microbial dysbiosis (c.difficile) has previously employed microbiota transplant treatment with great success in long-term health outcomes. Such treatments are shown to repopulate bacterial microenvironment and restore protective commensal bacterial load. A pilot study conducted by this study team trialed a novel intervention of a Nasal Microbiota Transplant in a small group of participants. Preliminary results suggested significantly improved CRS symptoms after treatment with a healthy donor microbiota transplant, compared to the pre-transplant baseline. The addition of a randomized-control trial with inclusion of a placebo group is the next step. In this study, investigators aim to perform a two-arm, double-blinded, phase II randomized controlled clinical trial in order to assess the efficacy of a Nasal Microbiota Transplant against a placebo in a cohort of CRS patients without Nasal Polyps (CRSsNP).

The objective of this study is to compare the effectiveness of batten grafts plus septoplasty and turbinate reduction (intervention arm) compared to septoplasty and turbinate reduction alone (control arm), both in terms of subjective and objective assessments.

This is a multi-center, randomized, double blind, placebo-controlled study to evaluate the efficacy, safety, PK, PD and immumogenicity of GR1802 injection 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). Patients will receive GR1802 injection or Placebo every 2 Weeks.

The study is being conducted to evaluate the efficacy, and safety of SHR-1905 injection in subjects with chronic rhinosinusitis with nasal polyps (CRSwNP), as well as to explore the reasonable dosage of SHR-1905 injection for CRSwNP.
