35 Clinical Trials for Various Conditions
Upper respiratory infections (URIs) have long posed a significant burden to the US healthcare system. Well before the coronavirus disease of 2019 (COVID-19) pandemic they have been among the most common acute outpatient illnesses, causing 75-100 million physician visits each year on average, and costing the health care system billions of dollars annually. This double-blind randomized placebo-controlled study tested the efficacy of two anti-inflammatory throat sprays against placebo and against a throat spray taken in conjunction with 325mg of aspirin, a well-known systemically administered cyclooxygenase (COX) inhibitor. Participants having common cold symptoms lasting less than two days were enrolled and given treatment to administer at home. Various common cold symptoms were assessed and measured via clinically validated self-assessment scales. Participants were screened for influenza and COVID-19 before enrollment and were excluded if found positive.

The study will also evaluate whether 3804-250A can prevent rhinovirus infection or common cold illnesses. The study will also evaluate the safety of 3804-250A.
Common Cold, Healthy
Pomegranate has a long history of use in folk medicine. There is vast data on the health benefits of pomegranate fruit and juice. Multiple studies have established the strong antioxidative effects of pomegranate polyphenols (primarily the ellagitannin punicalagin) and their health effects. A vast number of animal and human clinical studies have provided evidence on effect of pomegranate products on improving blood lipid profile, reducing blood pressure, improving endothelial function, anti-tumor activity, and its anti-atherosclerotic activity. We studied the protective effect of a pomegranate concentrate (POM Flu and Cold Formula®) in decreasing the incidence and duration of influenza-like illnesses and common cold among healthy adults.
Influenza, Common Cold, Cough, Headache, Fever
The design and interpretation of randomized trials is intimately connected to the use of "placebo". The nature and magnitude of placebo effects, however, is very poorly understood. This study will assess and compare placebo effects and physician interaction effects within a community-acquired common cold model. The goal of this study is to assess two kinds of placebo affects and how physician interaction effects; 1. The effect of receiving blinded placebo, compared to no treatment; and 2. The effect of receiving open-label active Echinacea treatment compared to blinded active treatment.
Common Cold
The purpose of this study is to determine whether three Echinacea preparations with different chemical compositions are effective for prevention or treatment of the common cold.
Common Cold
The purpose of this study to determine the therapeutic response of non-allergic rhinitis patients that have been subtyped as non-allergic rhinitis with local IgE elevation or non-allergic rhinopathy to intranasal capsaicin based on visual analog scale and optical rhinometry, to determine the prevalence of non-allergic rhinitis with local IgE elevation in this study's cohort of patients with non-allergic rhinitis identified by rhinitis history and negative skin testing for allergic rhinitis, and to determine the change, if any, in intranasal IgE levels after capsaicin treatment.
Non-allergic Rhinitis
The purpose of this study was to see if high dose esomeprazole (40mg bid) was effective in treating non-allergic rhinitis
Vasomotor Rhinitis
Nasal glucocorticosteroids (GCS) are considered first-line therapy for both allergic and non-allergic rhinitis.1-3 Nasal congestion can persist despite maximum treatment with intranasal GCS. No other drugs are superior to intranasal GCS in relieving nasal congestion. For example, antihistamines are not effective in relieving congestion.1 Oral decongestants are somewhat beneficial in relieving nasal congestion but can elevate blood pressure, cause restlessness, and cause urinary retention. Oxymetazoline, however, is a potent decongestant and the addition of it to a nasal GCS should add a considerable decongestant benefit. It may also be beneficial in patients with persistent nighttime congestion despite maximum dosages of nasal GCS. Oxymetazoline is currently recommended for three days use because of the proposed risk of rhinitis medicamentosa,4 which is increased nasal congestion caused by prolonged use of nasal decongestant sprays.5-8 The term RM was coined early in the twentieth century after several case reports described patients developing rebound congestion after using first generation intranasal decongestants such as privine hydrochloride and ephedrine for prolonged periods6,7. The histopathology and mechanism of RM has been based on animal models which may not be pertinent to humans.9-13 Studies using oxymetazoline, a newer intranasal decongestant, in individuals without rhinitis have shown conflicting evidence for the development of RM.14-16 For example, normal individuals without rhinitis using oxymetazoline three times daily for four weeks did not develop RM.17 Also, it is unknown the frequency of administration and dosage of oxymetazoline it takes to induce RM or whether RM is just a return to a patient's baseline nasal congestion as present before beginning oxymetazoline. It is also unknown whether RM is more likely or only occurs with older vasoconstrictors such as privine hydrochloride and ephedrine rather than oxymetazoline. Nasal GCS reduce the amount of rebound congestion in patients with perennial allergic rhinitis who have reportedly developed RM.18 Nasal GCS decrease nasal mucosa edema, recruitment of neutrophils and mononuclear cells, cytokine production, and late-phase nasal mediators.19-21 They may offer a protective benefit from the risk of developing RM. Oxymetazoline may also decrease inferior turbinate hypertrophy thereby permitting better adsorption of the nasal GCS. Hypothesis The addition of oxymetazoline to a nasal GCS for fourteen days will decrease the amount of congestion in subjects with allergic or non-allergic rhinitis with persistent congestion despite maximum recommended dosages of a nasal GCS. It is also hypothesized that nasal GCS protect against the development of RM secondary to oxymetazoline.

Respiratory Tract Infections, Influenza, Human, Common Cold
Colds and flu cause much loss of work and school. The purpose of this study is to try to reduce the transmission of colds and flu among household members with one of three interventions: some educational material, educational material and use of alcohol hand sanitizers, and educational material and use of alcohol hand sanitizers as well as face masks when somebody has symptoms of the flu. We will recruit 450 households in Northern Manhattan and each household will be randomly assigned to one of these three groups. We will then follow these households for 15 months to see how often they get cold and flu symptoms. We will also look at antibiotic use practices for symptoms of colds and influenza ; household member knowledge of prevention and treatment strategies for pandemic influenza and viral URIs; and rates of influenza vaccination among household members. When someone in the study has serious flu symptoms such as a high fever and cough or sore throat, we will also obtain a nasal culture (by swabbing the nose) to see if there is flu virus present.
Respiratory Tract Infections, Common Cold
This study examines the cold processes of children aged 6 to less than 14. Children will be seen by the study staff 6 days in a row during the course of their naturally-acquired colds. Nasal secretions will be examined for chemicals that the body creates during a cold. Skin cells will be collected by brushing the inside of the child's cheek with a small brush. The cells will be examined for genes that may hold control the creation of these chemicals.
Upper Respiratory Infection, Common Cold
OBOE is a prospective, pilot, parallel group RCT with the overall aim of examining the effect of a single dose of anti-IgE (omalizumab) vs. placebo administered at the onset of URIs in the fall season among highly exacerbation-prone, urban, and atopic youth aged 6-17 years with persistent asthma. OBOE will recruit and randomize participants over 3 years (3 annual cohorts of participants). Recruitment for each of the yearly cohorts of OBOE will begin in February. Each cohort will be followed for a 2-6-month run-in period with the objective to gain control of each participant's asthma and to stabilize the required controller medication step level. Participants will receive routine asthma care every 1-2 months (a total of 2-4 times) during run-in using a previously described algorithm developed by the Inner-city Asthma Consortium and successfully employed in the PROSE study. The primary outcome is the change in the amount of nasal IFN-α recovered by nasal fluid absorption between two time points, within 72 hours of onset of a URI as defined by onset of (or substantial worsening of) rhinorrhea, nasal congestion or sneezing (single or multiple symptoms) and 3-6 days after study drug injection.
