NCT00669799 ↗	Topical Antibiotic Use In Chronic Rhinosinusitis A Double-Blinded, Randomized, Placebo Controlled Study	Withdrawn	University of South Florida	N/A	2008-03-01	Chronic rhinosinusitis is a pervasive and costly disease. Recent estimates describe over 20 million Americans suffering from this diagnosis at a cost of over $4.3 billion per year. Primary intervention consists of oral antibiotics and nasal steroid sprays. A role for antifungal irrigation has also been proposed. Topical antibiotics are used by some physicians, but there are few reports in the published literature describing their use and establishing or refuting their efficacy. Sykes in 1986 performed a randomized, prospective, double-blinded study with 50 patients using topical nasal sprays with dexamethasone, tramazoline, and neomycin; dexamethasone and tramazoline without antimicrobial; and placebo. Both of the treatment groups showed improvement over placebo, but in those groups there was no significant difference in response rates between those patients receiving neomycin and those who did not. There were no adverse events reported. In the same year, Cuenant et al. reported success with neomycin-tixocortol irrigations in the treatment of chronic rhinosinusitis. Scheinberg and Otsuji and Vaughn and Carvalho describe their use of various nebulized antimicrobials (including aminoglycosides) in patients with recurrent sinusitis. Both are uncontrolled, retrospective studies showing improvement in symptom scores. Neither study reported any major side effects. Leonard and Bolger describe a case report and review their success with the use of topical Ceftazidime in 50 patients. Only one patient reported stinging sensation during administration. They reported no problems with antibiotic resistance. Studies by Davidson et al. , and Moss and King describe the use of topical antibiotics for sinusitis in patients with cystic fibrosis. They report improvement in sinusitis symptoms and reduction of need for revision sinus surgery in patients treated with surgery followed by topical intranasal tobramycin. They report no significant side effects. Dudley described the use of topical gentamicin in a case report of a patient with atrophic rhinitis. The patient had resolution of her complaints without any adverse symptoms. He also describes a study by Thornell showing success with streptomycin nasal sprays and reports work by Rubinstein demonstrating safe administration of gentamicin into the nose without absorption by the nasal mucosa. On balance, the literature describes topical antibiotics as a safe, but variably efficacious treatment for chronic rhinosinusitis. There is a paucity of prospective, randomized, blinded, and controlled studies. The purpose of this protocol is to describe a scientifically rigorous study of the use of broad spectrum antibiotic nasal sprays for chronic sinusitis. The patient population for this study will consist of patients who have a history of multiple sinus infections each year that require treatment with antibiotics. The patients in this study will have had recurrent infections despite prior medical and surgical intervention. They will fulfill the criteria for chronic rhinosinusitis without nasal polyposis. Treatment will include conventional treatment with oral antibiotics and a topical nasal steroid. In addition, patients will be randomized to receive either topical antibiotics or a vehicle placebo. The study will follow patients for a three month period. Patients will be monitored for improvement in radiographic findings and quality of life when compared to a randomized and double-blinded placebo group. The patient population identified for inclusion in this study will also be evaluated for allergy and humoral and innate immunodeficiency. Nasal lavage will be obtained from the study population and pre and post-treatment comparisons will be performed.
NCT00695435 ↗	Tobramycin Tear Concentrations	Completed	Alcon Research	Phase 1	2008-06-01	To evaluate the Tobramycin tear concentration values of TOBRADEX® Ophthalmic Suspension, Tobramycin 0.3% / Dexamethasone 0.05% Ophthalmic Suspension versus TOBREX® Ophthalmic Solution in normal volunteers.

Clinical Trials Update

Dexamethasone

Dexamethasone, a potent corticosteroid, has seen accelerated clinical activity amid the COVID-19 pandemic, especially following the landmark RECOVERY trial which demonstrated mortality benefits in severe COVID-19 cases [1]. Currently, numerous trials are investigating its efficacy beyond infectious diseases, including:

• Management of autoimmune disorders
• Adjunct therapy in cancer treatment
• Use in inflammatory conditions such as psoriasis and rheumatoid arthritis

As of 2023, over 120 active clinical trials globally are registered involving dexamethasone, with a significant focus on dosage optimization and delivery methods, including inhalation and sustained-release formulations [2]. Notably, particular interest is in evaluating its role in long COVID syndromes, aiming to modulate persistent inflammation (NCT04850296).

Tobramycin

Tobramycin, an aminoglycoside antibiotic primarily targeting Gram-negative bacterial infections, remains vital in cystic fibrosis (CF) management and healthcare-associated pneumonia. Current clinical investigations focus on:

• Inhaled formulations for CF patients to improve pulmonary function
• Combination therapies with other antibiotics to combat resistant strains
• Novel delivery systems, such as liposomal encapsulation, to enhance lung deposition and reduce systemic toxicity

Recent trials assess the efficacy of inhaled tobramycin in non-CF bronchiectasis and ventilator-associated pneumonia (VAP). For instance, a notable study (NCT04676720) evaluates liposomal tobramycin in resistant Pseudomonas aeruginosa infections [3]. Overall, over 60 global trials are active or recruiting, indicating ongoing clinical interest.
