Hi! My mom has st4 nsclc with Mets to the brain. She had one dose of Keytruda but ended up with Pnemonitis and on 15L of oxygen. She has thankfully recovered (mostly-still on 2L of oxygen). They are now ready to restart treatment and we’re waiting to hear what it will be. My question is has anyone been on another immunotherapy after an adverse reaction to Keytruda? Or done Keytruda again after an adverse reaction? Thanks in advance.
