• Patient has any other concurrent severe and/or uncontrolled medical condition that would, in the investigator's judgment, cause unacceptable safety risks, contraindicate patient participation in the clinical study or compromise compliance with the protocol (e.g., chronic pancreatitis, chronic active hepatitis, active untreated or uncontrolled fungal, bacterial, or viral infections etc.)

• Patient is currently receiving any of the following medications and cannot be discontinued 7 days prior to starting study drug (for details):
