Active clinical trials for "Cough"

The Pilot of Zinc Acetate to Improve Chronic Cough (ZICO) is a study of 36 patients with chronic refractory cough that will be used to (1) assess if zinc acetate (150 mg/day) will improve patient reported measures of cough, (2) to establish if treatment with zinc acetate is well tolerated, and (3) to determine if the trial logistics are feasible.

The primary objective of this study is to evaluate the safety of two doses of gefapixant (MK-7264) in Japanese adult participants with refractory or unexplained chronic cough.

This is a research study to find out if superior laryngeal nerve blocks are an effective way to reduce cough when compared to placebo (a substance without any medical value). Eligibility for the study include the following: age >18, cough history suggestive that the nerve to the voice box is overactive, non-smoker, Patients will be followed over time and assigned to either the treatment or placebo group at random. The treatment would be four superior laryngeal nerve blocks and the placebo would be four saline injections (the inactive substance). Study team will measure if the injection improved cough and ask patients to keep a log of symptoms and fill out questionnaires at each visit. After the four injections, patients will follow up in 3 months to see if cough has returned and if so, how severe the cough is.

Coughing during extubation of endotracheal tube (ETT) is a common problem that leads to poor surgical results including hemodynamic change, rebleeding at the surgical wound and wound dehiscence. Recently, lidocaine has been introduced for reducing coughing during extubation. However, data comparing routes of lidocaine application are lacking, thus, this study compared the combination of lidocaine sprayed on laryngeal inlet and cuff of ETT versus intravenous lidocaine injection for efficacy in reducing coughing

Cough of children is one of the most frequent events for which parents ask for a medical consult and it is a true challenge for pediatrics during daily practice. In the majority of cases, it is self-limiting, but its persistence could become exasperating and it could reduce quality of life and social activities. Even if inappropriate prescription of antitussive pharmacological treatment in children has been reduced, pediatrics prescribing attitudes do not still always are reflecting accurate treatment of cough. Furthermore, pediatric approach is always compromised by parental exaggerate perception of symptoms and usual consequent requirement of pharmacological prescription of antibiotics, that they consider the appropriate and effective therapeutic option for cough. The World Health Organization identifies honey as a potential demulcent treatment for cough. On the light of the above considerations and since available pediatric treatments for acute cough are limited by lack of demonstrated efficacy, a pediatric cough syrup product containing Acacia honey as well as specific fractions of resins, polysaccharides, saponins, flavonoids and sugars derived from Malva sylvestris extract, Inula helenium, Plantago major extract, Helichrysum stoechas (KalobaTuss) was developed to be clinically tested on persisting cough of children. Investigators evaluated through a randomized, double blind controlled clinical study the effects of KalobaTuss on persistent cough in children aging 3-6 years. The effects of Kalobatuss were compared with effects of placebo on nocturnal and daytime persistent cough for eight days. Objective of the study was to evaluate the clinical efficacy of KalobaTuss by using as primary endpoint the assessment of changes in day- and night-time cough score.

To determine the effectiveness of manually assisted cough technique on peak cough flow and pulmonary functions in patients with incomplete cervical spine injury. Previous studies were designed to target only a small sample. Level and American Spinal Cord Injury Association (ASIA) scale were not specified so this study covers this aspect.

Researchers in this study want to find the optimal therapeutic dose of drug BAY1817080 for patients with long-standing cough with or without clear causes (refractory and/or unexplained chronic cough, RUCC). Study drug BAY1817080 is a new drug under development for the treatment of long-standing cough. It blocks proteins that are expressed by the airway sensory nerves which are oversensitive in patients with long-standing cough. This prevents the urge to cough. Researchers also want to learn the safety of the study drug and how well it works in reducing the cough frequency, severity and urge-to-cough. Participants in this study will receive either the study drug or placebo (a placebo looks like the test drug but does not have any medicine in it) tablets twice daily for 12 weeks. Observation for each participant will last about 18 weeks in total. Participants will be asked to wear a digital device to record the cough and to complete questionnaires every day to document the symptoms. Blood samples will be collected from the participants to monitor the safety and measure the blood level of the study drug.

The primary objective of this study will be to evaluate the efficacy of gefapixant (MK-7264) in reducing cough frequency as measured over a 24-hour period. It is hypothesized that at least one dose of gefapixant is superior to placebo in reducing coughs per hour (over 24 hours) at Week 24.

This study is designed to evaluate the effect of GSK2339345 relative to placebo on the number of coughs in patients with Chronic Idiopathic Cough (CIC) administered by an Aqueous Droplet Inhaler (ADI). The primary aim is to investigate the efficacy of GSK2339345 on reducing objective cough frequency in CIC patients. The secondary aim of this study is to investigate the efficacy of GSK2339345 in inhibiting a hypertussive cough response elicited by capsaicin and citric acid in CIC patients which have a hyperresponsive cough reflex. Following the screening visit, all eligible subjects will attend the unit for dosing at Visits 1-7. At Visits 1, 2 and 3 (Part A of the study), subjects will receive two doses of either GSK2339345 or placebo, 4 hours apart and will undergo 8 hours of cough monitoring. At Visits 4 and 5 (Part B of the study) and Visits 6 and 7 (Part C of the study), subjects will be administered a single dose of either GSK2339345 or placebo. Subjects will then undergo capsaicin (Part B) or citric acid (Part C) tussive challenge and will undergo cough monitoring for 1 hour post dose. The maximum study duration will be approximately 11 weeks, including 3 weeks screening and 2 weeks follow-up. Approximately 30 patients will be randomised into the study, such that approximately 24 patients complete dosing and critical assessments.

The purpose of this trial is to determine the efficacy of spinal cord stimulation, using wire leads, to produce an effective cough in patients with spinal cord injuries.
