That’s different for each type of cancer that Keytruda is used to treat. And your individual response to Keytruda treatment will also be unique based on the form of cancer you have and your overall health.
In many clinical studies, Keytruda was successful in shrinking the size of people’s tumors and reducing how quickly their cancer worsened.
For example, in one study, up to 6% of people taking Keytruda for melanoma had their cancer completely go away. In another study, 22% of people taking Keytruda for classical Hodgkin lymphoma (cHL) had their cancer completely go away.
The number of people who had their cancer partially go away was typically much higher in each study. (For example, it was up to 47% for people with cHL).
