简要总结
This is a randomized, open-label, multicenter Phase III clinical trial, designed to evaluate the efficacy and safety of SYS6010 versus docetaxel in participants with Locally Advanced or Metastatic EGFR Wild-type Non-squamous Non-small Cell Lung Cancer who Have Failed Standard Therapy. The primary Objective is to evaluate the efficacy of SYS6010 versus docetaxel in participants with EGFR wild-type locally advanced or metastatic non-squamous non-small cell lung cancer (nsq-NSCLC). Secondary Objectives includes safety, quality of life, immunogenicity, biomarkers, and efficacy correlations of SYS6010 compared to docetaxel in the same patient population.
详细描述
This is a randomized, open-label, multicenter, Phase III clinical study designed to evaluate the efficacy and safety of SYS6010 compared with docetaxel in participants with locally advanced or metastatic EGFR wild-type nsq-NSCLC who have failed standard therapy.
Approximately 506 participants will be enrolled and randomized 1:1 to receive either SYS6010 or docetaxel. Randomization will be stratified by: (1) brain metastases (yes vs no) and (2) EGFR high expression (yes vs no). EGFR protein expression will be assessed by immunohistochemistry (IHC).
Key eligibility criteria include: age ≥18 years; histologically or cytologically confirmed locally advanced or metastatic nsq-NSCLC; and EGFR mutation negative confirmed for the EGFR wild-type population. For participants who are driver gene-negative, prior therapy must have included immunotherapy and platinum-based chemotherapy ± anti-angiogenic therapy with documented treatment failure. For participants who are driver gene-positive, prior therapy must have included appropriate targeted therapy for the driver alteration and platinum-based chemotherapy, with treatment failure.
The study includes a screening/baseline period, treatment period, safety follow-up (30 days after the last dose), PFS follow-up, and survival follow-up.

Stage IIIB or IIIC patients unsuitable for surgical resection or radical chemoradiotherapy, or Stage IV NSCLC patients. EGFR mutations (currently approved by regulatory authorities for targeted therapy) must be confirmed negative. If test results are unavailable, participants need to provide tumor tissue to undergo genetic testing.

- •Driver gene-negative population must have failed only immune therapy and platinum-based chemotherapy ± anti-angiogenic therapy (limited to first-line regimens approved by regulatory authorities).
- •Other driver gene-positive populations must have received and failed only targeted therapy for the driver gene and platinum-based chemotherapy ± anti-angiogenic therapy (limited to first-line regimens approved by regulatory authorities).
- •5. Have at least one measurable lesion confirmed by CT or MRI according to RECIST v1.1 criteria;
- •ECOG performance status score 0-1;
- •Expected survival ≥3 months as judged by the investigator.
- •Within 7 days before the first administration, the body organs and bone marrow function meet the requirements, defined as follows (Note: For hematological tests, participants must not have received blood component transfusion, G-CSF, TPO, TPO-RA, IL-11, or EPO within 2 weeks prior to randomization):
- •ANC ≥1.5×10⁹/L
- •Platelets (PLT) ≥100×10⁹/L
- •Hemoglobin (HGB) ≥100 g/L
- •Serum creatinine (Cr) ≤1.5×ULN AND creatinine clearance ≥50 mL/min (calculated by Cockcroft-Gault formula)
- •Total bilirubin (TBIL): ≤1.5×ULN for patients without liver metastases; ≤3×ULN for patients with Gilbert's syndrome or liver metastases
- •ALT/AST: ≤2.5×ULN for patients without liver metastases; ≤5×ULN for patients with liver metastases
- •APTT and INR ≤1.5×ULN
- •Female participants of childbearing potential must have a negative pregnancy test within 7 days before randomization. All participants must agree to use effective contraception from the time of signing the ICF until 7 months after the last dose. During this period, female participants must not be breastfeeding, and male participants must refrain from sperm donation.
