This is a double-blind Phase 3 clinical trial evaluating the efficacy and safety of TRS003 and paclitaxel-carboplatin versus China-approved bevacizumab and paclitaxel-carboplatin in patients with unresectable, locally advanced, or metastatic non-squamous non-small cell lung cancer (NSCLC). Approximately 608 patients will be enrolled in this study from America, Europe, and Asia. Patients who sign the informed consent and meet the inclusion criteria, will be randomized (1:1) to receive either TRS003 in combination with paclitaxel and carboplatin or China-approved bevacizumab in combination with paclitaxel and carboplatin for 4 to 6 cycles.


This is a randomized, double-blind, multinational, multicenter, active-control, parallel two-group Phase 3 clinical trial evaluating the efficacy and safety of TRS003 plus paclitaxel-carboplatin versus China-approved bevacizumab plus paclitaxel-carboplatin in patients with unresectable, locally advanced, recurrent or metastatic non-squamous NSCLC. Approximately 608 subjects will be enrolled into this study from America, Europe and Asia. Patients who sign the informed consent and meet the inclusion criteria will be randomized (1:1) to receive either TRS003 or China-approved bevacizumab in combination with paclitaxel-carboplatin for 4 to 6 cycles. Patients will be stratified by region (Asia, Europe and America), gender, and cigarette smoking habit (previous smoker, smoker and non-smoker).

Patients will receive either TRS003 (Arm A), or China-approved bevacizumab (Arm B) first followed by the administration of paclitaxel and carboplatin. TRS003 or China-approved bevacizumab will be administered at 15 mg/kg by intravenous (IV) infusion on Day 1 of each cycle (every 3 weeks, Q3W). Paclitaxel will be administered at a dose of 200 mg/m^2 by IV infusion (over 3 hours) Q3W on Day 1 of each cycle and carboplatin will be administered at an area under the plasma concentration-time curve (AUC) 6 mg/mL/ min (the maximum dose capped at 900 mg) by IV infusion (over 15 - 30 minutes) Q3W on Day 1 of each cycle. Each cycle is 3 weeks. Treatments will continue until disease progression, death, intolerable toxicity, withdrawal of consent, investigator decision, or completion of 4-6 cycles of therapy. Maintenance therapy may be given at the discretion of the patient's primary oncologist.

Efficacy will be evaluated by the investigator per RECIST v1.1 (Eisenhauer et al., 2009). Efficacy evaluation will be performed at baseline and every 6 weeks 7 days during the 4-6 cycle combination treatment periods. After completion of combination treatments, efficacy evaluations will be performed every 9 weeks 7 days (if patients received maintenance therapy). The analysis of Investigator-determined objective response rate (ORR) (RECIST v1.1) will be based on information obtained prior to Week 19. Investigator-determined duration of response (DOR) and progression-free survival (PFS) will also be evaluated according to RECIST v1.1. Data on overall survival (OS) will be collected. Central radiology review will not be required. However, for the purpose of quality control, the Sponsor may elect to have some or all tumor assessments to be reviewed by an independent imaging vendor.

Safety will be evaluated throughout the study. Adverse events will be recorded from the time of informed consent. Safety will be assessed based on periodically physical examination findings, vital signs, Eastern Cooperative Oncology Group (ECOG) performance status, laboratory variables (hematology, coagulation tests, serum chemistries, urinalysis and pregnancy tests), and electrocardiogram (ECG) findings. Adverse events and laboratories will be graded according to National Cancer Institute (NCI) CTCAE v5.0.

Immunogenicity will be assessed in all patients who received at least one dose of TRS003 or China-approved bevacizumab. Samples will be assessed for the development of antidrug antibodies to either TRS003, or China-approved bevacizumab. Neutralizing antibodies (NAb) will assessed in samples that are antidrug antibody (ADA) positive. Trough pharmacokinetics (PK) samples will be collected and will be analyzed for interpretation of immunogenicity data and exploratory analysis when needed.
