Filter by:This study is a multicenter, randomized, double-blind, placebo-controlled Phase Ib/II clinical trial to evaluate the effectiveness, safety, tolerability and pharmacokinetics (PK) of TCR1672 Tablets in patients with refractory chronic cough.
A 2-period crossover study for the treatment of cough in patients with Refractory Chronic Cough via Nalbuphine ER (NAL ER). Each period will last 21 days and are separated by 21 days. Subjects will be randomized in Treatment Period 1 to either NAL ER or matching placebo and evaluated for 21 days. After completion of the first phase, subjects who received NAL ER will crossover to placebo and subjects who received placebo will crossover to NAL ER to complete Treatment Period 2.
This is a phase II study that will investigate the efficacy, safety and tolerability of HRS-2261 in subjects with refractory chronic cough using a double blind, placebo controlled, randomized study design.
Part 1 will evaluate the safety, tolerability and PK of single doses of three dose levels of NTX-1175 drug substance administered by dry powder inhaler (NOC-110) compared to a single dose reference nebulizer (NOC-100) treatment in healthy participants. Part 2 will evaluate the safety, tolerability and PK of multiple doses of NTX-1175 drug substance administered by dry powder inhaler (NOC-110) to participants with refractory chronic cough. Part 2 will also evaluate the treatment effect of multiple doses of one dose level of NTX-1175 drug substance administered by dry powder inhaler (NOC-110).
This is a randomized, double-blind, placebo-controlled, parallel-arm, Phase 3 study of BLU-5937 in participants with Refractory Chronic Cough (RCC).
This is a randomized, double-blind, placebo-controlled, parallel-arm, Phase 3 study of BLU-5937 in participants with Refractory Chronic Cough (RCC).
This is a prospective case - control study to investigate ATP level in induced sputum and cough sensitivity to ATP in subjects with refractory chronic cough. 60 refractory chronic cough and 30 matched healthy controls were recruited. Medical history records, cough severity assessment, induced sputum for ATP measurement, ATP evoked cough and capsaicin evoked cough were completed. The difference of sputum ATP level between patients and control and the correlation between sputum ATP level and cough sensitivity to ATP were analyzed.
This research study is evaluating the effectiveness of escalating doses of Amitriptyline and Duloxetine in reducing cough frequency in patients with refractory chronic cough (RCC)
Chronic cough (TC), defined by a duration exceeding 8 weeks, is a particularly frequent symptom with a prevalence observed at 9.6% 1. Chronic cough is the cause of a major handicap for patients with a impact on their quality of life 2. Although CT is common, management is often delicate and complex. In studies, asthma, gastroesophageal reflux disease, posterior flushing, rhino-sinusitis, or taking tussigenic medications are common causes of chronic coughs. However, chronic refractory or unexplained cough, which corresponds to cough for which no cause has been found or the treatments directed against the cause of the cough have not made it possible to resolve the cough, is a real problem in practice. nick3. There is currently no prospective data in France on the characteristics of chronic cough (etiologies, response to treatment) and the percentage of refractory cough. The aim of the study is to constitute a French prospective multicenter hospital cohort of chronic cough patients in order to identify, for the first time in France in a prospective and multicenter manner, the frequency of patients with refractory cough among chronic cough patients.
This is a randomized, double-blind, placebo-controlled, parallel-arm, Phase 2b adaptive dose-finding study of BLU-5937 in participants with Refractory Chronic Cough (RCC).
