• Malignancy in the last 5 years before screening (except adequately treated basal or squamous cell skin cancer)
• Have a history of alcohol or substance abuse within the preceding 6 months that, in the opinion of the Investigator, may increase the risks associated with study participa-tion or study agent administration, or may interfere with interpretation of results,

• Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study

Életkor
