The purpose of the study is to evaluate safety, pharmacokinetics and efficacy of WX-0593 alone in the treatment of advanced cancer.
The first part is a single-arm, phase 1, open label, dose-escalation design in patients with anaplastic lymphoma kinase(ALK)/receptor tyrosine kinase(ROS1) Positive ALK/ROS1-positive solid tumor. The second part is an expansion in non-small cell lung Cancer (NSCLC) characterized by abnormalities in anaplastic lymphoma kinase(ALK) expression.

RECRUITINGMaximum tolerated dose(MTD)
The MTD is determined by the number of the participants in cohort who suffer a dose-limiting toxicity (DLT). The MTD is defined as the former dose at which more than one third of the participants develop a DLT. If no DLTs are observed, the MTD is not reached.

Objective Response Rate (ORR)
Primary efficacy endpoint is a change in the proportion of subjects showing overall objective response rate (ORR) from baseline to final tumor assessment point after treatment. As Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria, the percentage of subjects indicating PR (partial response) and CR (complete response) will be calculated. According to RECIST 1.1 criteria, complete response (CR) - the disappearance of all target lesions and partial response ( PR ) - at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum of longest diameter.
Time frame: From fist administration of WX-0593 to 28 days after last medication.
Progression-free survival (PFS)
PFS defined as the time from baseline to first observed disease progression or death from any cause.
Time frame: From fist administration of WX-0593 to 28 days after last medication.
Disease Control Rate (DCR)
DCR is the percentage of patients with best response of CR, PR or Stable Disease (SD). SD was defined as neither sufficient shrinkage to qualify for a PR nor sufficient increase to qualify for PD, taking as reference the smallest sum of the longest diameter.
Time frame: From fist administration of WX-0593 to 28 days after last medication.
Duration of Response (DOR) and so on
The DOR is defined as the time from the date of the first response CR/PR (whichever is first recorded) to the date on which progressive disease (PD) is first noted or date of death.
Time frame: From fist administration of WX-0593 to 28 days after last medication.
