Criteria

Inclusion Criteria:

1. ≥18 years.

2. Female or male;

3. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2.

4. Expected survival no less than 12 weeks.

5. Patient should have at least one measurable lesion (RECIST 1.1); Lesions previously treated with radiotherapy can be considered target lesions only if there is a clear evidence of progression after radiotherapy.

6. Histologically or cytologically confirmed advanced ALK-positive NSCLC in upper first-class hospitals，or histologically or cytologically confirmed advanced ROS1-positive NSCLC in a central laboratory. Admission of ROS1-positive patients will be based on the positive test results confirmed by the central laboratory or by the local-approved method.

1. Patients with ALK-positive NSCLC who had been progressive disease after at least 12 weeks of continuous treatment with crizotinib .

2. Patients with ROS1-positive NSCLC who failed in standard treatment (eg.resistant /intolerance of crizotinib or chemotherapy).

3. Patients with ROS1-positive NSCLC who cannot accept chemotherapy.

4. ROS1-positive NSCLC patients who could not afford crizotinib treatment.

7. Patients with or without asymptomatic CNS metastases, or symptomatic brain metastasis after treatment stabilized for more than 4 weeks, and with stopping systemic sex hormone therapy for more than 2 weeks.

8. Organ functions should meet the following requirements (Blood components, cell growth factors, drugs that stimulate the growth of WBC or platelets, or drugs used to correct anemia are not permitted within 14 days prior to the laboratory examination): ANC≥1.5*10^9/L PLT≥90*10^9/L,Hb≥90 g/L, Total Bilirubin （TBIL）≤1.5*Upper Limit of Normal（ULN） ( Gilbert's Syndrome TBIL ≤3.0*ULN and DBIL≤1.5*ULN )，Alanine Transaminase （ALT）and Aspartate Aminotransferase （AST）≤2.5*ULN. For liver metastasis patients, ALT and AST≤5*ULN, Cr≤1.5*ULN, LVEF≥50%.

9. Any surgery, prior radiotherapy (except for palliative radiotherapy)/procedures must be completed at least 4 weeks prior to starting the treatment with study drug. Palliative radiotherapy must be completed within 48 hours prior to starting treatment.

10. Subject understands and voluntarily provides informed consent.

Exclusion Criteria:

1. Received any prior ALK inhibitors other than crizotinib.

2. Patients with brain meningeal metastasis.

3. Any clinically significant cardiovascular disease within 6 months prior to the first dose of the investigational drug, including but not limited to: myocardial infarction, severe/unstable angina, coronary artery/peripheral artery bypass graft, congestive heart failure, cerebrovascular accident (including transient ischemic attack).

4. Two consecutive corrected QT interval (QTc) > 480 ms through ECG examination during screening, patients with NCI-CTCAE v4.03 Grade ≥2 arrhythmia, Grade ≥2 heart failure, atrial fibrillation and ventricular fibrillation of any grade, or clinically significant supraventricular or ventricular arrhythmia requiring treatment or intervention.

5. Concomitant use of medications that may cause QTc prolongation or induce Torsades de pointes within 14 days prior to the first dose of the investigational drug or during treatment.

6. Continuous use of corticosteroids for more than 30 days, or require chronic use of corticosteroids or other immunosuppressants.

7. Past history of a large area of diffuse/interstitial pulmonary fibrosis, or known history of Grade 3 or 4 interstitial pulmonary fibrosis or interstitial lung disease, including a history of pneumonitis, hypersensitivity pneumonitis, interstitial pneumonitis, interstitial lung disease, obliterative bronchiolitis, or pulmonary fibrosis, but does not include local radiation pneumonitis or radiation-induced pulmonary fibrosis.

8. Patients with Grade > 1 nausea, vomiting, or diarrhea (CTCAE 4.03), other GI dysfunction or GI disease that may potentially affect drug absorption (such as ulcerative disease or malabsorption syndrome).

9. Subject received other clinical trial treatment within 1 month prior to the first dose of the investigational drug (if the medication received is a marketed drug, then refer to exclusion criteria #11).

10. Patients who are HBsAg-positive and/or HBcAb positive and HBV DNA >10^3 copies/mL, or HCV antibody-positive, or syphilis antibody- positive or known HIV infected.

11. No more than 2 weeks between the most recent use of another anti-cancer treatment (half life ≤3 days) and the first dose of the investigational drug, or the most recent use of another anti-cancer treatment (half life > 3 days) is less than 4 weeks. Patients previously treated with crizotinib could take WX-0593 tables after 1 week from the last dose.

12. Patients who cannot suspend the use of a strong CYP3A4 inducer or inhibitor at least 1 weeks prior to this study and during the study. These drugs include but are not limited to carbamazepine, phenobarbital, phenytoin, rifabutin, rifampicin, rifapentine, tipranavir, ritonavir, St. John's wart, and ketoconazole.

13. Patients who cannot suspend the use of a CYP3A4 substrate at least 1 weeks prior to this study and during the study, and the therapeutic index is low.

14. Pregnant or lactating female patients or a positive pregnancy test at baseline for females of childbearing potential.

15. Childbearing potential female patients who are unwilling to use effective contraceptive measures during the entire course of the study and within 6 months after the end of the study, or male patients who plan to have children.

16. Concurrent diseases that may seriously affect patient safety or impact patient completion of the study as determined by the investigator (such as clinically uncontrolled hypertension (blood pressure > 160/110 mmHg), severe diabetes, or thyroid disease).

17. Drug or alcohol abuse. Alcohol abuse refers to drinking 14 units of alcohol per week:

1 unit = 285mL of beer, or 25mL of spirits, or 100mL of wine.

18. History of definitive neurological or mental disorder, including epilepsy or dementia.

19. Patients with other malignant tumors within 3 years prior to screening (except for cured basal cell carcinoma of the skin, cervical carcinoma in situ, thyroid carcinoma in situ, and papillary thyroid carcinoma).

20. Patients with added risks associated with the study or may interfere with the interpretation of study results as determined by the investigator, or deemed unsuitable by the investigator and/or sponsor.
