Active clinical trials for "Respiratory Tract Infections"

This study will assess the efficacy and safety of OM-85 compared to placebo in reducing the number of respiratory tract infections (RTIs) in children aged between 6 months and 5 years.

Acute respiratory tract infections (ARTIs), such as acute rhinosinusitis (ARS) and acute otitis media (AOM), are common worldwide and caused by viruses or bacteria entering the body through the mouth and nose. AOM frequently occurs in young children and is caused by bacterial reflux into the middle ear. ARS is a relatively common ARTIs and can occur at many ages. To accurately diagnose disease, careful clinical examination and accurate clinical judgment are required, as making a reasonable treatment regimen with the decision to use antibiotics. Probiotics have long been known to have beneficial effects on the digestive system. Not only limited to the gastrointestinal tract but probiotics are also known for their role in reducing infections in the respiratory system. Recently, the investigators have successfully conducted a clinical trial of nasal-spray Bacillus spore probiotics in children infected with respiratory syncytial virus (RSV), and the data show that the probiotics can rapidly and effectively relieve symptoms of RSV-induced ARTIs while exhibiting strong impacts in reducing viral load and inflammation. Here, the investigators conducted a study that directly spraying probiotics into the nose can effectively support to treatment of both ARS and AOM. The aim of the study about to evaluate the safety and effectiveness of nasal-spraying probiotics containing spores of Bacillus subtilis and Bacillus clausii in the supportive treatment of patients with ARS and AOM. Study Population: sample size is 120. Description of Sites: the study is carried out at Thai Binh Medical University Hospital and Thai Binh Children's Hospital. Description of Study Intervention: 120 eligible patients are divided into 2 groups (n=60/group) including the ARS group and the ARS accompanied by the AOM (ARS & AOM) group. 60 patients in each of the above groups were randomly assigned to two subgroups (n=30/subgroup): Patients in the Control-ARS and Control-ARS & AOM subgroups received the routine treatment and three times per day nasal-spraying 0.9% NaCl physiological saline. In contrast, the patients in the Navax-ARS and Navax-ARS & AOM subgroups received three times per day nasal-spraying LiveSpo Navax® in addition to the same standard of care treatment. The standard treatment regimen is 3-7 days, depending on the severity of the disease when the patient arrives for the exam and the progression of the disease during the treatment period. Study duration: 18 months

This project aims to study the benefits of probiotics namely Bifidobacterium infantis YLGB-1496 in modulating gut microbiota of children with respiratory symptoms, among pre-school children in Malaysia aged >12 months old, <7 years old.

A Phase 2a, randomized, double-blind, placebo-controlled, multiple ascending dose study in patients who are hospitalized with presumed pneumonia requiring supplemental oxygen therapy. The purpose of this study is to examine the safety, tolerability and efficacy of AV-001 Injection administration daily to the earlier of day 28 or EOT (day prior to hospital discharge). A total of 120 eligible patients (20 patients in each of cohort 1, 2 and 3 and 60 patients in cohort 4) will be recruited from up to 25 participating institutions/hospitals. Patients will be randomized in a 1:1 ratio to receive either AV-001 Injection or AV-001 placebo Injection, together with standard of care (SOC).

Phase II/Phase III study to evaluate the safety and efficacy of Ramatroban 75 mg tablet against Placebo in subjects hospitalized for pneumonia due to SARS-CoV-2 infection. Approximately 324 eligible subjects will be randomized in a 1:1 ratio to one of the two treatment groups. Group I: Ramatroban 75 mg tablet + Standard of care; Group II: Placebo + Standard of care. Phase 2 Primary Objective: To evaluate the safety of Ramatroban 75 mg tablet with the standard of care against Placebo with the standard of care in COVID-19 hospitalized subjects. Secondary Objective: To assess the efficacy of Ramatroban 75 mg tablet with the standard of care against Placebo with the standard of care in COVID-19 hospitalized subjects. Phase 3 Primary Objective: To evaluate the efficacy of Ramatroban 75 mg tablet with the standard of care against Placebo with the standard of care in COVID-19 hospitalized subjects. Secondary Objective: To evaluate the safety of Ramatroban 75 mg tablet with the standard of care against Placebo with the standard of care in COVID-19 hospitalized subjects. Long COVID [Follow-up Phase- Objectives- (Phase 2 & 3)] To examine lipid mediators, specifically thromboxane A2, prostaglandin D2, F2-isoprostane and/or their metabolites in convalescent subjects after treatment. To assess the efficacy of Ramatroban administered during the acute illness in preventing/mitigating subsequent development of long COVID / PASC

Background: Recurrent respiratory papillomatosis (RRP) is a rare disease that causes wart-like growths in the airways. These growths come back when removed; some people may need 2 or more surgeries per year to keep their airways clear. Better treatments are needed. Objective: To see if a drug called bevacizumab can reduce the number of surgeries needed in people with RRP. Eligibility: People aged 18 and older with recurrent RRP; they must need surgery to remove the growths in their airways. Design: Participants will be screened. Their ability to breathe and speak will be evaluated. They will have an endoscopy: a flexible tube with a light and camera will be inserted into their nose and throat. They will have a test of their heart function and imaging scans of their chest. Participants will have surgery to remove the growths in their airways. Bevacizumab is given through a small tube placed in a vein in the arm. After the surgery, participants will receive 11 doses of this drug: every 3 weeks for 3 doses, and then every 6 weeks for 8 more doses. They will come to the clinic for each dose; each visit will be about 8 hours. Tissue samples of the growths will be collected after the second treatment; this will be done under general anesthesia. Participants may undergo apheresis: Blood will be drawn from a needle in an arm. The blood will pass through a machine that separates out the cells needed for the study. The remaining blood will be returned to the body through a second needle. Follow-up will continue for 1 year after the last treatment.

Respiratory syncytial virus (RSV) infection and bacterial co-infection are the most common causes of pneumonia. Currently, there is no vaccine available for RSV prevention, and the use of the antiviral medication ribavirin is not widely recommended for children. Therefore, the primary treatment approach follows the general protocol for pneumonia, and oxygen therapy is recommended for all cases of pneumonia with respiratory failure. However, in children, the treatment of RSV and bacterial pneumonia remains supportive to prevent bacterial co-infection and respiratory failure. Probiotics have emerged as promising and safe options for supporting the treatment of acute respiratory tract infections (ARTIs) and reducing dependence on antibiotics in recent years. In this study, investigators propose that the direct administration of probiotics through a nasal spray can offer rapid and effective symptomatic treatment for children with pneumonia who require oxygen therapy due to RSV and bacterial co-infections. The aim of the study is to evaluate the effectiveness of nasal-spraying probiotics containing spores of two bacterial strains, Bacillus subtilis and Bacillus clausii (LiveSpo Navax), in preventing and supporting the treatment of severe pneumonia in children (who require oxygen therapy) caused by RSV infection and bacterial co-infection. Study population: The sample size was 100, and the study was conducted at the Vietnam National Children's Hospital. Description of Study Intervention: All 100 eligible patients were randomly divided into two groups (n = 50/each): Patients in the Control group received routine treatment and were administered 0.9% NaCl physiological saline 3 times/day, while the patients in the Navax group received LiveSpo Navax 3 times/day in addition to the same standard of care treatment. The standard treatment regimen typically lasts for 5-7 days, but its duration can be extended based on the severity of the patient's respiratory failure. Study duration: 12 months.

The purpose of this study is to investigate the effects of a training program in patients that have suffered a COVID infection

The study hypothesis is that cromolyn, when combined with standard COVID-19 treatment, will improve patient symptoms and reduce the number of days to improved quality of life. Investigators will study the effects of adding cromolyn to the standard treatment of hospitalized patients with COVID-19 pneumonia and who require supplemental oxygen. Cromolyn will be administered as a nebulized treatment four times a day for four days followed by intranasal administration for two weeks. Investigators may also screen for biomarkers that could indicate inflammatory responses and treatment-induced improvement. Participants will receive either study drug or placebo which will be administered by nebulization for 4 days followed by 14 days of intranasal administration. Participants will be followed while in the hospital and then as outpatients up to day 21 following randomization.

Respiratory viruses pose a permanent threat to humans and society as demonstrated by the current Covid-19 pandemic. Novel drugs and vaccines provide a means for controlling illness. Infections and symptomatic presentation of illness may be reduced, but it remains to be determined to which extent viral shedding and transmission (e.g. by silent transmitters) can be controlled. Lack of such activity may result in continuing viral spread by assumed healthy but asymptomatic spreaders. Echinacea is an established and readily-accessible product with demonstrated in vitro antiviral activity (including coronaviruses). This study aims to estimate the potential of different Echinacea formulations (head-to-head) to reduce concentration infectivity and shedding of SARS-CoV-2 under in vivo conditions.
