Sinusitis

Chronic rhinosinusitis (CRS) is one of the most common medical conditions in the US, affecting an estimated 13% of adults, or some 30 million people. It accounts for 12.5 million physician office visits each year and an annual health care expenditure of $5.8 billion (National Health Interview Survey 2009, CDC). Major symptoms include nasal obstruction, facial pain/pressure, nasal discharge, purulence in the nasal cavity, and loss of smell. These symptoms significantly impact patient quality of life, even compared to chronic debilitating diseases such as diabetes and congestive heart failure. Topical therapies play an integral role in the management of CRS, and high-volume irrigation delivery (e.g., neti pot, squeeze bottles) is more effective for achieving distribution to the sinuses than other topical delivery methods such as nasal sprays, nebulizers, or atomizers. Saline irrigations have been recommended in a number of clinical scenarios, including initial management of CRS and postoperative care. High-volume irrigations have also shown benefits for medication delivery, such as with mupirocin and corticosteroids. However, due to the intricate and variable anatomy of the human nasal airway, the efficacy of topical irrigations is inconsistent and difficult to predict. Previous studies from our group and others have shown that nasal irrigant may not reliably penetrate all sinuses, and the effectiveness varies depending on specific sinuses, head positions, injection angle, pressure, flow rates, and other factors. We currently do not have a clear understanding of the optimal delivery technique(s). In efforts to improve these outcomes, the efficacy of topical irrigation delivery to target sinuses is an area of active research. Yet, investigations have been limited by labor-intensive methodologies, such as cadaver studies or using colored dyes followed by endoscopy to visualize where the irrigation might have reached. Other studies have used irrigations with iodinated contrast followed by computed tomography (CT) scans to determine which sinuses collect contrast material. Similarly, technetium 99m sulfur colloid and fluorescein have also been used as tracers to visualize the distribution of sinus irrigations. These labor-intensive techniques are difficult to apply to a large sample size. They increase patient risk and commonly capture only where the irrigation fluid has been at the end of irrigation, but not the details of irrigation flow paths that would allow us to understand why the irrigation outcomes vary. From both patients' and clinicians' perspectives, the lack of clear prediction of patient-specific irrigation outcomes can be frustrating, as clinicians prescribe a rigorous daily irrigation routine but have no assurance that what patients are doing is effective. When symptoms fail to improve after courses of irrigation, it is difficult to determine whether the added medication is not working, or the irrigation does not reach clinically relevant targets deep within the sinuses. Many patients and surgeons thus opt for systemic medication or surgery, which increases risk of overmedication, growth of resistant organisms, systemic side effects, and serious risk from surgery. The purpose of this study was to propose a novel idea: applying three-dimensional (3D)-printing technology based on individual patients' computed tomography (CT) scans to determine an optimal personalized nasal irrigation strategy (head positions, angle of injection, flow rates, etc.).

The aim of the present study is to establish a modified minimally invasive surgical technique for sinus floor augmentation with a residual bone height of 3-6mm. Hypothesis: The investigators expect that the present surgical technique allows to achieve an adequate implant bed of at least 10mm height after a healing period of 3-5 months. Further the modification of the technique enables a reduced patient stress level.

EFC18419 is a multinational, randomized, double-blind, placebo-controlled, parallel-group, Phase 3 study with 3 treatment groups. The purpose of the study is to evaluate the efficacy, safety and tolerability of 2 dosing regimens of itepekimab compared to placebo as add-on therapy to intranasal corticosteroids (INCS) in male and female participants with chronic rhinosinusitis with nasal polyps (CRSwNP) aged 18 years of age and older. Study details include: * The study duration per participant (4-week screening, 52-week treatment, 20-week safety follow-up) will be up to 76 weeks. For participants transitioning to the LTS18420 study, the study duration will be 56 weeks. * The treatment duration will be up to 52 weeks. * The number of visits will be 9 site visits and 20 phone/home visits.

The goal of this clinical study is to evaluate the safety, tolerability, and pharmacokinetics (PK) of VVN432 Nasal Spray in healthy volunteers (Phase Ia) and in patients with chronic rhinosinusitis (Phase 1b). This study consists of two parts (Phase 1a and Phase 1b): Phase 1a (SAD) is a single-center, randomized, double-masked, vehicle-controlled study to assess the safety, tolerability, and PK of VVN432 Nasal Spray in healthy adult subjects. Phase 1b (MAD) is a multi-center, randomized, double-masked, vehicle-controlled study to assess the safety, tolerability, PK/PD, and preliminary efficacy of VVN432 Nasal Spray in patients with chronic rhinosinusitis.

It is a multicenter, adaptive open-label, non-randomized, dose-escalation, and expansion study to assess safety, tolerability, and efficacy following intracochlear administration of SENS-501.

Participants will receive Adebrelimab intravenously in combination with carboplatin /Cisplatin and etoposide during the induction phase (2 Cycles ). Thereafter, participants will receive concurrent chemoradiotherapy(thoracic radiation therapy and SBRT for metastases,combination with carboplatin /Cisplatin and etoposide for 1-2 Cycles).Then participants will receive Adebrelimab combination with carboplatin /Cisplatin and etoposide for 1-2 Cycles,followed by Adebrelimab maintenance until persistent radiographic PD, intolerable toxicity or withdrawal of consent during the maintenance phase.

The main purpose of this study is to evaluate the efficacy and safety of lebrikizumab in participants with chronic rhinosinusitis and nasal polyps treated with intranasal corticosteroids. The study will last about 18 months.

This is a multicentre, open-label, single-arm, phase IIIb study is to describe changes from baseline in (1) participant-reported nasal congestion as evaluated by the nasal congestion score (NCS) and (2) participant-reported sino-nasal symptoms as evaluated by sino-nasal outcome test, 22 item (SNOT-22) following initiation of tezepelumab treatment. Approximately 60 sites in 10 countries will enrol adult patients with physician determined surgery eligible CRSwNP. The study is divided into 3 periods as described below: * Screening Period (from Week -4 until Week 0, up to 4 Weeks) * Treatment period (Week 0 to Week 24) * Safety Follow-up Period (Week 24 to Week 36)

Respiratory signs and symptoms consisting of wheeze, cough, and breathlessness are obtained in a manual fashion through history taking and physical examination by the healthcare professional. Auscultation of the lung assesses airflow through the trachea-bronchial tree and is helpful in diagnosing various respiratory disorders. AeviceMD is a wearable device that can acquire and process lung sounds, thus assisting in the detection of abnormal lung sounds. The primary objective of this study is to determine if AeviceMD can detect wheeze of pediatrics and adults as accurately as a physician through auscultation. The secondary objective is to investigate if AeviceMD can be used for remote auscultation of breath sounds.
