Evidence of active malignancy within the last 3 years prior to the first dose
Concurrent use of any of the prohibited food or drugs required in protocol within 12 days prior to the first dose of administration of lorlatinib
Other severe acute or chronic medical or psychiatric condition, or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, would make the subject inappropriate for entry into this study
