12. Patients who could not discontinue therapy with potent CYP3A4 inhibitors or inducers within 1 week prior first dosing, or patients who need therapy with CYP3A4 inhibitors or inducers during the study.
13. Patients received medications known to be metabolized by CYP3A4 and with narrow therapeutic indices, who could not discontinue within 1 week prior to the start of WX-0593 administration. Patients who need therapy with those medications during the study.
14. Females who are pregnant or breastfeeding.
15. Patients with childbearing potential must agree to use adequate contraception for the duration of treatment and for 6 months after the study.
16. Drug abusers and alcoholics.
17. History of definite nerves or psychosis diseases including epilepsy or dementia.
18. History of other malignancy.
19. Concurrent condition that in the investigator's opinion would jeopardize compliance with the protocol or would impart excessive risk associated with study participation that would make it inappropriate for the patient to be enrolled.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: WX-0593 Tablets; The first part is a dose-escalation design in patients with ALK/ROS1-positive solid tumor. The second part is an expansion in non-small cell lung Cancer (NSCLC) characterized by abnormalities in ALK expression.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maximum 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.	28 days

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Tmax of WX-0593	Pharmacokinetics of WX-0593 by assessment of time to Cmax	28 days
Cmax of WX-0593	Pharmacokinetics of WX-0593 by assessment of maximum plasma WX-0593 concentration.	28 days
Cmin of WX-0593	Pharmacokinetics of WX-0593 by assessment of minimum plasma WX-0593 concentration.	28 days
AUC of WX-0593	Pharmacokinetics of WX-0593 by assessment of area under the plasma concentration time curve from zero to infinity	28 days

Cssmin of WX-0593	Cmin of WX-0593 at steady state	28 days
Cssmax of WX-0593	Cmax of WX-0593 at steady state	28 days
Css-av of WX-0593	Mean plasma concentration of WX-0593 at steady state	28 days

CLs of WX-0593	total plasma,serum or blood clearance of WX-0593 after administration	28 days
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.	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.	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.	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.	From fist administration of WX-0593 to 28 days after last medication.
