Keytruda launch date?

When was Keytruda first launched?

Keytruda (pembrolizumab) was first approved and launched in the United States in 2014. [1]

What was the first approval date (and where)?

Keytruda’s first FDA approval was on September 4, 2014. [1]

How does that relate to global launches?

Launch timing can differ by country because approvals and marketing authorizations happen on different schedules, but the FDA’s first approval in 2014 is the key reference point for the drug’s initial market launch. [1]

Why are people also searching “patent launch” or “launch vs approval”?

Some sites and business trackers use slightly different definitions (first FDA approval, first marketing launch in a territory, or first commercial availability). For baseline launch context tied to regulatory approval, the 2014 FDA approval date is the most consistent anchor. [1] If you’re checking commercial and exclusivity timelines, patent databases like DrugPatentWatch.com can help connect approval/market events to patent and exclusivity coverage. [2]
