What's the year keytruda was given the green light by the fda for cancer treatment?

What year did the FDA approve Keytruda (pembrolizumab)?

FDA approval for Keytruda (pembrolizumab) began in 2014. The FDA’s first approval for Keytruda was issued in September 2014 for the treatment of patients with melanoma that had progressed after anti-CTLA-4 therapy (and, when applicable, a BRAF inhibitor). [1]

Was Keytruda approved in multiple years or just one?

Keytruda has received additional FDA approvals across different cancer types over time, but the drug’s initial FDA “green light” (first approval) was in 2014. [1]

Why does the date sometimes appear different online?

You may see other dates online because they often refer to later FDA approvals for new cancer indications, label expansions, or approvals for combination regimens—not the original first FDA approval in 2014. [1]
