The primary purpose of the study was to compare progression-free survival of JYP0322 vs. platinum-based doublet chemotherapy in patients previously treated with ROS1-TKIs. Patients in the chemotherapy arm are given the option to switch to JYP0322 after BICR confirmed progressive disease (PD), while also have the choice to pursue with other drugs after discussing with their physicians.
This is a phase III, open label, randomized study assessing JYP0322 (150 mg, orally, tid) versus platinum-based doublet chemotherapy in subjects with confirmed diagnosis of ROS1 fusion positive NSCLC, who have progressed following prior therapy with one or two approved ROS1 Tyrosine Kinase Inhibitor (ROS1-TKI) agents and whose tumors harbors a ROS1 fusion positive. Subjects must agree to provide a biopsy for central confirmation of ROS1 fusion status. A total of 207 patients will be randomly assigned in a 2:1 ratio to receive oral JYP0322 (at a dose of 150mg tid) or intravenous pemetrexed (500 mg per square meter of body-surface area) plus carboplatin (target area under the curve 5 \[AUC5\]) every 3 weeks for up to six cycles. Patients without disease progression after four cycles of platinu

Randomization to either JYP0322 or platinum-based doublet-chemotherapy on Day 1 of every 21d cycle in a 2:1 (JYP0322: platinum-based doublet-chemotherapy) ratio
Once subjects on the platinum-based doublet chemotherapy arm are determined to have objective radiological progression according to RECIST 1.1 by the investigator and confirmed by BICR, they will be given the opportunity to begin treatment with JYP0322 150mg tid. These subjects may continue treatment with JYP0322 if they are continuing to show clinical benefit until disease progression as judged by the investigator.
JYP0322, 150 mg, administered orally three times daily (tid) after meals; sample size (N) = 60.
Progression Free Survival (PFS) by BICR Assessment
Per Response Evaluation Criteria in Solid Tumours (RECIST v1.1) assessed by MRI or CT: Progressive Disease (PD): \>= 20% increase in the sum of diameters of TLs and an absolute increase in sum of diameters of \>=5mm (compared to the previous minimum sum) or progression of NTLs or a new lesion. PFS is the time from date of randomization until the date of PD (by BICR assessment) or death (due to any cause) regardless of whether the patient withdrew from randomized therapy. Patients who had not progressed or died at the time of analysis were censored at the time of the latest date of assessment from their last evaluable RECIST 1.1 assessment.
Time frame: UP to 3 years
Progression Free Survival (PFS) by investigators Assessment
Per Response Evaluation Criteria in Solid Tumors (RECIST v1.1) assessed by MRI or CT: Progressive Disease (PD): \>= 20% increase in the sum of diameters of TLs and an absolute increase in sum of diameters of \>=5mm (compared to the previous minimum sum) or progression of NTLs or a new lesion. PFS is the time from date of randomization until the date of PD (by investigators assessment) or death (due to any cause) regardless of whether the patient withdrew from randomized therapy. Patients who had not progressed or died at the time of analysis were censored at the time of the latest date of assessment from their last evaluable RECIST 1.1 assessment
Time frame: UP to 3 years
Overall Survival (OS)
OS is defined as the time from date of randomization until the date of death (due to any cause) regardless of whether the patient withdrew from randomized therapy. Patients who had not died would be censored at the last known alive date.
Time frame: UP to 5 years
Objective Response Rate (ORR) by Investigator and BICR assessment
Per Response Evaluation Criteria in Solid Tumors (RECIST v1.1) assessed by MRI or CT: Complete Response (CR): Disappearance of all target and non-target lesions and no new lesions; Partial Response (PR): \>= 30% decrease in the sum of diameters of Target Lesions (compared to baseline) and no new lesions. ORR is the percentage of patients with at least 1 visit response of CR or PR prior to progression or any further therapy.

Time frame: RECIST tumor assessments every 6 weeks from randomization up to 3 years.
Duration of Response (DOR) by Investigator and BICR assessment
Per Response Evaluation Criteria in Solid Tumors (RECIST v1.1) assessed by MRI or CT: Complete Response (CR): Disappearance of all target and non-target lesions and no new lesions; Partial Response (PR): \>= 30% decrease in the sum of diameters of Target Lesions (compared to baseline) and no new lesions. DOR is the time from the date of first documented response until the date of documented progression or death in the absence of disease progression for patients who had conformed CR or PR.
Time frame: RECIST tumor assessments every 6 weeks from randomization up to 3 years.
Disease Control Rate (DCR) by Investigator and BICR assessment
Per Response Evaluation Criteria in Solid Tumors (RECIST v1.1) assessed by MRI or CT: Complete Response (CR): Disappearance of all target and non-target lesions and no new lesions; Partial Response (PR): \>= 30% decrease in the sum of diameters of Target Lesions (compared to baseline) and no new lesions; Stable disease (SD): Neither sufficient shrinkage to qualify as a response nor sufficient growth to qualify as progression; Progressive Disease (PD): \>= 20% increase in the sum of diameters of TLs and an absolute increase in sum of diameters of \>=5mm (compared to the previous minimum sum) or progression of NTLs or a new lesion. DCR is the percentage of patients with best response of CR, PR or SD at \>=6 weeks, prior to any progressive disease (PD).
Time frame: RECIST tumor assessments every 6 weeks from randomization up to 3 years.
Time to Response (TTR) by Investigator and BICR assessment
Per Response Evaluation Criteria in Solid Tumors (RECIST v1.1) assessed by MRI or CT: Complete Response (CR): Disappearance of all target and non-target lesions and no new lesions; Partial Response (PR): \>= 30% decrease in the sum of diameters of Target Lesions (compared to baseline) and no new lesions; Stable disease (SD): Neither sufficient shrinkage to qualify as a response nor sufficient growth to qualify as progression; TTR is defined as time from the date of randomization to the first documented response for patients who had confirmed CR or PR at least once.
Time frame: RECIST tumor assessments every 6 weeks from randomization up to 3 years.
