• Major surgery or significant traumatic injury that has not been recovered from by 14 days before the initiation of study drug
• Current or prior participation in a study of an investigational agent or investigational device within 2 weeks of first dose of study treatment

Más betegség

• Presence of leptomeningeal disease
• Interstitial lung disease that is symptomatic or may interfere with the detection or management of suspected drug-related pulmonary toxicity
• Known medical condition that, in the investigator's opinion, would increase the risk associated with study participation or study drug(s) administration or that would interfere with the interpretation of safety results
• Positive test for: a. Hepatitis B virus using Hepatitis B virus surface antigen (Hepatitis B virus surface antigen) test b. Hepatitis C virus (HCV) using HCV ribonucleic acid or HCV antibody test that indicates acute or chronic infection c. Exception: Individuals with a positive test for HCV antibody but no detection of HCV ribonucleic acid indicating no current infection are eligible

• Inadequate hepatic function
• Inadequate pancreatic function

• Provides signed and dated informed consent
• Stated willingness to comply with all study procedures and availability for the duration of the study
• Age 18 or older
