Criteria

Inclusion Criteria:

Patients must meet all of the following criteria to be eligible for enrollment into the study:

≥ 18 years of age
Histologically or cytologically confirmed locally advanced or metastatic NSCLC
Positivity of ROS1 fusion is determined by the local qualified laboratories by using the FISH, RT-PCR or NGS assay, and the subject must provide archival tumor tissue sample for the confirmation by a sponsor-designated central laboratory
The subject is either TKI treatment naïve(Cohort A)， or has disease progression following the treatment of crizotinib （Cohort B）
The patient with brain metastases is either asymptomatic, or neurologically stable for at least 2 weeks prior to study entry
Prior therapies (including chemotherapies [less than 3 lines of regimen], radiotherapy [except for palliative], or surgery) should be completed at least 2 weeks prior to study entry. The palliative radiotherapy (≤10 times) should be completed within 48 hours prior to study entry. Any acute toxic effect must be resolved to CTCAE Grade ≤1 except for alopecia
At least one measurable target tumor lesion (as accessed by RECIST v1.1) that has not been irradiated
ECOG Performance Status: 0 or 1
Patient with a life expectancy ≥ 3 months based on the judgement of investigators

Adequate organ functions defined by the following criteria：

Aspartate Aminotransferase (AST) and Alanine Aminotransferase (ALT) ≤2.5 x ULN; or ≤5 x ULN， if there is liver metastases involvement；
Total serum bilirubin ≤1.5 x ULN；
Absolute neutrophil count（ANC） ≥1500/µL；
Platelet count≥100,000/µL；
Hemoglobin≥8.0 g/dL；
Serum creatinine ≤2 x ULN. 11. Evidence of a personally signed and dated informed consent document indicating that the patient has been informed of the pertinent aspect of the study 12. Willingness and ability to comply with the study scheduled visits, treatment plans, laboratory tests and other procedures 13. Male and female patients of childbearing potential must agree to sue effective methods of contraception throughout the study and for 90 days after the last dose of study medication.

Exclusion Criteria:

Patient presenting with any of the following criteria will not be included in the study：
