The drug was developed by Merck & Co. The phase III clinical trial for this medicine was stopped early after a review showed it was highly effective and had a good safety profile. Merck announced in 2014 that it would apply for regulatory approval in 2015.[4]

In 2016, Merck discontinued development of odanacatib and announced it would not seek regulatory approval after analysis discovered an increased risk of stroke.[5]

This drug was developed at Merck Frosst in Montreal.
