 | May 23, 2017 05:21AM ET

Merck (NYSE:MRK) presented data from a phase II study on its pipeline candidate MK-7264 (formerly AF-219) at the American Thoracic Society (ATS) Annual Conference. The study was designed to evaluate the safety, efficacy and therapeutic dose range of MK-7264 for the treatment of chronic cough.

Data from the study revealed that the highest dose of 50 mg, given twice daily, resulted in reduction of Awake Cough Frequency (coughs/hour), the primary endpoint, by 37% from baseline compared to placebo after 12 weeks of treatment. The 50 mg dose also demonstrated a reduction in patient-reported cough severity. However, lower doses (7.5 mg and 20 mg) were not statistically significant.

The company plans a discussion with regulatory agencies for initiating phase III clinical development of MK-7264 by the end of 2017.

Shares of Merck have outperformed the Zacks-classified Large Cap Pharma industry in the last year. The stock has gained 15.2% during the period, while the broader industry witnessed an increase of 4.3%.
