Study of the Efficacy and Safety of SCH 619734 in Subjects With Chronic Cough From an Unknown Cause (Study P04888)
26. november 2013 opdateret af: Merck Sharp & Dohme LLC
Study of the Efficacy and Safety of SCH 619734 in Subjects With Chronic Idiopathic Cough
This is a randomized, double-blind, placebo-controlled, crossover, single center study of SCH 619734 in subjects with chronic cough from an unknown cause.
Subjects will be randomized to receive SCH 619734 or placebo for 7 days with 7 days' follow-up.
After a 6 week washout period, subjects will be crossed over to the other treatment.
The primary objective is to evaluate the effectiveness of SCH 619734 in reducing cough reflex sensitivity as determined by a challenge with capsaicin, an agent that induces cough.

Beskrivelse
Inclusion Criteria:
- Male and female subjects, 18 to <65 years old, with a history of a dry cough for >6 months.
- By history, evaluation of gastroesophageal reflux disease was done and ruled out by a minimum of an 8-week trial of antacid therapy (with a proton-pump inhibitor [PPI] given twice daily) with no clinical response in cough.
- By history, if there are clinical signs and symptoms of postnasal drip, these signs and symptoms will have been treated with a combination of an antihistamine and decongestant for a minimum of 8 weeks with no clinical response in cough.
- By history, if there are clinical signs and symptoms of asthma, these signs and symptoms will have been treated with a combination of an inhaled steroid and a short-acting beta-agonist for a minimum of 8 weeks with no clinical response in cough.
Exclusion Criteria:
- Subjects with current evidence of clinically significant pulmonary (especially conditions that involve coughing), hematopoietic, cardiovascular, hepatic, renal, neurologic, psychiatric, autoimmune, or other disease that precludes the subject's participation in the study. In particular, diabetics, uncontrolled hypertensives, and subjects with clinically significant cardiomyopathy, prostatic hypertrophy, glaucoma, seizure disorders, and psychiatric disorders are to be excluded from participation in this study.
- Subjects with asthma or chronic obstructive pulmonary disease who require chronic use of inhaled or systemic corticosteroids.
- Subjects receiving concurrent prohibited medications unless they observe the washout period prior to the baseline visit. These medications would include opioid- and non-opioid-containing cough suppressants and potent CYP3A inhibitors, such as ritonavir, ketoconazole, and clarithromycin. Subjects receiving ACE inhibitors or MAOIs will be excluded from the study.
- Subjects with a history of allergies to more than two classes of medications.
- Current smokers, ex-smokers who stopped smoking in the previous 6 months, or subjects with a cumulative smoking history >10 pack-years will be excluded. (Pack-years is a way to measure the amount a person has smoked over a long period of time. It is calculated by multiplying the number of packs of cigarettes smoked per day by the number of years the person has smoked, eg, a 10 pack-year history is equal to smoking 1 pack per day for 10 years or 2 packs per day for 5 years, etc.)
