What was measured

To characterize the preliminary pharmacokinetics including Cmax f X-396 given as a single agent

Analysis population: Histologically or cytologically confirmed diagnosis of advanced solid tumor malignancy that is not responsive to at least 1 prior standard regimen for advanced disease or for which there is no approved therapy or for patients that decline standard therapy.For Phase II of the study, patients must have NSCLC with ALK genomic alterations.
