Merry, Thanks for posting this information about the new dosage and protocol of Keytruda (pembrolizumab) for all cancer types for which this drug is used, including lung cancer. I moved your post to this discussion where members are talking about this drug.

I too would like to hear from anyone who is getting the new dose of 400 milligrams (mg) every six weeks instead of the current dose of 200 mg every three weeks.
