View clinical trials related to Nasal Polyposis.
Filter by:"Nasal polyposis is a chronic inflammation of the sinonasal mucosa which is characterized by the development of polyps in the sinonasal cavities. In the general population, its prevalence is 4% with a clear increase from the age of 50 years. When drug treatment is not effective, and the patient's quality of life is impaired, surgery is proposed. It allows to widen the nasal cavities with aerodynamic and acoustics effects on speech. There are few studies, that have focused on the impact of NP and its treatment on speech. Yet there is a real demand from patients to obtain answers related to the impact of this surgery on their voice. Preoperatively and postoperatively, the resonance will be disturbed: polyps will impacted the quality of the nasal sounds. And after surgery, the new anatomical shape can create an excessive resonance in the nasal cavities. Indeed, there is a diversity of acoustic effects that differ according to the sinuses involved, the nature and type of surgery and the anatomical and physiological specificities of the patient. The impairment of acoustic properties after surgery is diverse and little known. The surgery improves the communication between sinuses and nasal cavities but the real impact on nasal resonance still unknown. The particularity of this pathology stands in the obstruction of the sinonasal cavity by polyps. On this study, it represents a model of nasality disturbance/impairment ? Indeed, all aspects of nasality will be altered : the articulation by the obstruction of the sino-nasal cavities, the aerodynamic by a disturbance of the circulation of the airflow within the nasal cavity, acoustics by an alteration of the resonance of this flow, and finally the perception of speech by others where the comprehension of speech is difficult. Thus, the investigators wish to observe this dysfunction in a multipara metric way in order to have an accurate approach. This population is therefore ideal. In preoperative, it will allow to measure by aerodynamic, articulatory, acoustic, and perceptive data taking this dysfunction, to give precise answers. Then, postoperatively, these measurements will be repeated to observe a return to the expected functioning of the nasal cavity. Indeed, the cavities being no longer congested, a greater flow of nasal air would be expected, which would have acoustic consequences on the resonance of nasal sounds. This could be accentuated because of the new anatomical configuration due to the surgery. Perceptually, the voice after surgery should no longer be considered as pathological. In addition to the linguistics aspect, this population has the particularity of having a strongly impacted quality of life. The investigators would therefore like to measure this impact on quality of life before and after surgery. For this study, the main objective is to measure the articulatory, aerodynamics, acoustics and perceptive impact of the nasal polyposis on speech before and after surgery. the secondaries objectives are to: - Compare the differences in aerodynamic, acoustic, articulatory and perceptual changes between the ""presence of polyps in the nasal and sinus cavities"" group and the ""presence of polyps in the sinus cavities"" group - Compare the modifications on the speech of the pathology before and after surgical treatment - Identify the elements related to the quality of life impacted by this pathology. - Identify the glottic compensation strategies induced by the pathology - Compare preoperative and postoperative nasal resonance and the relationship between nasal and sinus cavities using 3D models - Validate the adequacy of the nasality-speech questionnaire for patients with sinonasal polyposis"
nasosinus polyposis (=PNS) is a chronic inflammatory disease of the nasal cavity and sinus cavity with a prevalence of 2 to 4% in the general population. The functional impact of PNS has a major impact on one's quality of life.Medical treatment, nasal irrigations and local glucocorticoids as well as short treatment of oral glucocorticoids have shown a short-term benefit versus placebo. Surgery improves the efficacy of local treatments, but 40% of patients have a recurrence of polyps at 18 months and 20% of patients require a surgery recovery at 5 years. The development of monoclonal antibodies directly targeting the inflammatory way is a real public health issue. Bachert C. et al recently demonstrated the efficacy of Dupilumab (anti-IL-4/13 antibody) injected subcutaneously on the overall symptomatology of PNS. The marketing authorization (AMM) for the first biotherapy to be available soon includes PNS's severe nature and resistance to treatment, although there is no consensus definition or score to characterize this severity. This study aims at developping a score for assessing severity in PNS. We suggest that this assessment strategy could be applied to the PNS. The originality and the innovative character of this project is the statistical modeling behind the creation of the score. Thus, the importance of symptoms, anatomical and biological factors, the estimation of the quality of life of the patients, the level of care use and the number of surgeries all become measurable indicators that are a direct reflexion of the severity and the control of PNS, called latent variables because they cannot be directly measured. To consider this detail, modeling using structural equations seems optimal to develop a severity score (PSI score) of PNS in order to personalize the therapeutic care of patients. Main Objective: To develop a severity score for PNS using latent variable modeling: Polyps Severity Index (PSI)
Chronic rhinosinusitis with nasal polyposis (CRwNP) is an inflammatory disease of the nasal mucosa. It is presented with severe stuffiness, nasal discharge, facial pressure/pain, and sleep disorders. It leads to severe inconvenience to social life and the quality of life. The first step standard medical therapy consists of the topical intranasal or systemic corticosteroids. Surgery should be considered in the case of medical treatment failure. However, the recurrences are common after both surgery and medical therapies in severe disease and usually require revision surgeries or high dose corticosteroid regimens. On the contrary, either the revision surgeries or the high dose corticosteroid therapies are not capable of preventing the recurrences, treatment failures. Besides, revision surgeries usually lead to high complication rates and high dose corticosteroids usually cause severe adverse effects. The use of the short course topical intranasal corticosteroids after the surgery is generally advocated for these patients. However, the recurrence rates are still high. Hence a new and effective maintenance treatment algorithm with no severe adverse effects is required. The hypothesis of the clinical trial is an estimated symptom recovery and superiority in both efficacy and safety by the use of low-dose methylprednisolone or methotrexate as compared to the standard maintenance therapy in treatment-resistant CRwNP patients. Therefore, the results of the present study are believed to provide data on novel maintenance therapy and suggest an alternative to the topical intranasal corticosteroids or the high-risk revision surgery.
This is a randomized, double-blind, placebo-controlled, parallel-group, international, multicenter, Phase 3 study to evaluate the efficacy and safety of repeat dosing of benralizumab 30 mg administered subcutaneously (SC) versus placebo in patients with severe nasal polyposis.
Nasal polyposis (NP) is a disease affecting 4% of the population. This disease is frequently accompanied by olfactory disorders (41%-84% of patients) that affect patients' quality of life. The aim of this study is to show brain activity differences in olfactory areas before and after surgery in each patient and between patient groups (normosmic, hyposmic and anosmic one) using functional Magnetic Resonance Imaging (fMRI). Brain activity will be measured by the intensity of brain signals and of the size of olfactory areas during olfactory stimulation before and after surgery. We suppose that fMRI could predict whether or not the patient will be able to recover smell after surgery.
This is a 24-week, open-label, multi-center study designed to assess the efficacy and safety of OPN-375 186 μg twice a day in subjects with nasal polyps using Nasoendoscopic video. The total planned number of subjects is approximately 10, with each subject receiving OPN-375 186 μg twice a day.
The aim of this present study is to investigate the use of benralizumab as treatment for severe nasal polyposis. The effect of benralizumab on nasal polyps will be assessed over a 56 weeks of treatment period in patients with severe bilateral nasal polyposis who are still symptomatic despite standard of care therapy, i.e current use of intranasal corticosteroids (INCS) and prior surgery and/or use of systemic corticosteroids. The first 200 patients that complete the 56-week treatment will have a 6 month follow-up (FU) period without dosing.
The ENCORE Study is designed to evaluate the repeat administration of the S8 Sinus Implant in chronic sinusitis (CS) patients with recurrent nasal polyps.
Chronic rhinosinusitis (CRS) with nasal polyps is a particularly challenging form of chronic rhinosinusitis in several ways. Patients have significantly more severe symptom burden and worse quality of life than patients with chronic rhinosinusitis without nasal polyps. Many patients return to the health care providers with persistent symptoms after repeated medical and surgical treatment. Patients have usually tried several different types of treatments, ranging from less invasive procedures to extensive surgical treatment. The surgical treatment is often repeated several times. The most common surgical treatment is functional endoscopic sinus surgery, another established procedure is Vidian neurectomy. The main object of this pilot study is to investigate the safety of onabotulinumtoxin A towards the sphenopalatine ganglion (SPG) in CRS patients with nasal polyps. Efficacy data will also be collected to provide indication on whether future placebo-controlled studies should be performed. Onabotulinumtoxin A inhibits the secretion of acetylcholine, blocking the parasympathetic reflex cascade in the SPG. As a result, the investigators expect less mucosal swelling, secretion and nasal polyps. The duration of such a blockade is believed to last for 3-9 months and will not lead to damage of the nerve. This study opens up for improved treatment with less complications.
This is a phase 2 study to evaluate multiple doses of AK001 across 2 active doses. Pharmacodynamic activity will also be evaluated.
