Overview
Brief Summary
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.
Detailed Description
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.
Study Treatments:
SYS6010: intravenous infusion 4.5 mg/kg Q3W. Docetaxel: intravenous infusion 75 mg/m² Q3W. Treatment will continue until meeting any protocol-defined treatment discontinuation criteria.
Dose modifications may include dose interruption, dose reduction, and permanent discontinuation.
Safety Assessments: Safety will be assessed from informed consent through 30 days after the last dose, including collection of all adverse events (AEs), clinical symptoms, vital signs, and laboratory abnormalities, and assessment of relationship to study treatment. Safety-related examinations (e.g., physical examination, ECOG performance status, laboratory tests) will be performed during screening/baseline and throughout treatment.
Efficacy Assessments: Tumor response will be evaluated per RECIST v1.1. The first post-randomization tumor assessment will occur at 6 weeks (+7 days). Subsequent assessments will be performed every 6 weeks (±7 days) through Week 54 (excluding the first assessment), and every 12 weeks (±7 days) from Week 55 onward, and at the end of treatment if no assessment has been performed within the prior 4 weeks. Participants who discontinue treatment prior to disease progression will enter PFS follow-up until disease progression, initiation of new anticancer therapy, death, loss to follow-up, or withdrawal (whichever occurs first).
Pharmacokinetics and Immunogenicity: Participants in the SYS6010 arm will undergo blood sampling for pharmacokinetics (PK) and immunogenicity assessments during the study.

Inclusion Criteria
- •1\. Voluntarily participate in this clinical study, understand the study procedures, and be able to sign the written ICF (Informed Consent Form);
- •Age ≥18 years, with no restriction on sex;
- •Patients with pathologically confirmed locally advanced or metastatic EGFR wild-type non-squamous non-small cell lung cancer (nsq-NSCLC). 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.
- •4\. Meet either of the following requirements regarding prior treatment for locally advanced or metastatic EGFR wild-type nsq-NSCLC:
- •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):
Exclusion Criteria
- •Histologically or cytologically confirmed small cell lung cancer, squamous cell carcinoma, neuroendocrine carcinoma, or sarcomatoid carcinoma
- •Patients with: Leptomeningeal metastasis, brainstem metastasis, spinal cord metastasis and/or compression, or active CNS metastases.
- •Exception: Supratentorial and/or cerebellar metastases (excluding midbrain, pons, or medulla) are allowed if: Received local therapy (e.g., radiation/surgery) Stable for ≥2 weeks before randomization (no new lesions/enlargement on imaging, stable/improved neurological symptoms). No corticosteroids or ≤10 mg prednisone (or equivalent) daily.
- •Other malignancies within 3 years before randomization, except: Cured basal/squamous cell skin cancer, superficial bladder cancer, prostate/cervical carcinoma in situ.
- •Known allergies: To any component of SYS6010 or humanized monoclonal antibodies. Contraindications/hypersensitivity to docetaxel.
- •Residual toxicities from prior antitumor therapy \> Grade 1 (per NCI-CTCAE v6.0), except: Grade 2 alopecia or other toxicities deemed non-risky by investigators.
- •Prior treatment with topoisomerase I inhibitors (including ADCs).
- •Inadequate washout periods:
- •Major surgery (excluding biopsies) within 4 weeks before first dose.
- •Last antitumor therapy before first dose:

Outcomes
Primary Outcomes
PFS (Progression-Free Survival) assessed by IRC (Independent Review Committee) in the EGFR high-expression population.
Time Frame: Up to approximately 22 months
PFS is defined as the time from the date of randomization to the first documentation of PD as assessed by IRC per RECIST v.1.1, or death due to any cause, whichever occurs earlier.
