  • People with a history of or current heart rhythm problems, or other conditions that increase the risk of a specific type of heart electrical abnormality (QT prolongation), such as heart failure or a genetic heart condition
  • People who have had major surgery within the past 4 weeks, wide-area radiation therapy within the past 4 weeks, limited-area radiation therapy within the past 2 weeks, any anti-cancer treatment within the past 2 weeks, or another experimental drug within 4 weeks or 5 half-lives of that drug (whichever is shorter)

  • People with a known active serious infection anywhere in the body
  • People with a known history of or currently active scarring/inflammation of the lungs (interstitial lung disease, drug-induced lung disease, or radiation pneumonitis) that required steroid treatment
  • People who have had a heart attack, severe unstable chest pain, or significant heart failure within the past 6 months (those with these conditions more than 6 months ago may be considered if heart function is normal and they have no cardiac symptoms — confirm with trial site)
  • People with known severe chronic kidney disease
  • People who test positive for HIV, hepatitis B surface antigen, or hepatitis C antibody (although people who test positive for hepatitis C antibody but negative for active hepatitis C virus may still be considered — confirm with trial site)
  • People with another separate active cancer, unless it is a very early-stage or previously cured cancer of specific types (such as early cervical changes, treated skin cancer, or any cancer fully treated more than 5 years ago — confirm with trial site)
  • Women who are able to become pregnant, or men whose partners could become pregnant, who do not agree to use effective contraception during the study and for a specified period after the last dose of study drugs
  • People who have previously been treated with certain immunotherapy drugs (checkpoint inhibitors such as anti-PD-1, anti-PD-L1, or anti-CTLA-4 therapies), except in certain specific cohorts where prior immunotherapy is part of the eligibility criteria
  • People who have received a live vaccine (such as measles, mumps, rubella, chickenpox, yellow fever, or BCG) within the 30 days before starting study treatment
