About this study

Official title: A Randomized, Open-label, Multicenter Phase III Study Comparing SYS6010 With Docetaxel in Patients With Locally Advanced or Metastatic EGFR Wild-type Non-squamous Non-small Cell Lung Cancer Who Have Failed Standard Therapy

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.

Read the 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. PFS (Progression-Free Survival) assessed by IRC (Independent Review Committee) in the EGFR high-expression population.

    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.

    Measured: Up to approximately 22 months

  2. OS (Overall Survival) in the overall population

    Overall survival is defined as the time from the date of randomization to the date of death due to any cause. In the absence of confirmation of death, survival time will be censored at the last date the participant is known to be alive.

    Measured: Up to approximately 39 months

Secondary outcomes (10)
  1. Progression Free Survival (PFS) evaluated by investigator

    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.

    Measured: Up to approximately 22 months

  2. Objective Response Rate (ORR)

    Objective response rate is defined as the percentage of participants with a confirmed complete response (CR) or partial response (PR) per RECIST v.1.1.

    Measured: Up to approximately 22 months

  3. Duration of Response (DOR)

    DOR is defined as the time from the date of the first confirmed objective response (CR or PR that is subsequently confirmed) to the date of the first documented disease progression (PD) per RECIST v1.1 or death from any cause, whichever occurs first.

    Measured: Up to approximately 22 months

  4. Disease Control Rate (DCR)

    The percentage of participants who experience a best response of CR, PR or stable disease (SD).

    Measured: Up to approximately 22 months

  5. Incidence of adverse events

    Measured: Up to approximately 21 months

  6. Quality of life assessed by EORTC QLQ-C30

    Quality of life will be assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). Scores are linearly transformed to a 0-100 scale. For Global Health Status/QoL and functional scales, higher scores indicate better health status/functioning; for symptom scales/items, higher scores indicate worse symptom burden.

    Measured: Up to approximately 21 months

  7. Quality of life assessed by EORTC QLQ-LC13

    Quality of life will be assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Lung Cancer 13 (EORTC QLQ-LC13). Scores are linearly transformed to a 0-100 scale, and higher scores indicate worse lung cancer-related symptoms (greater symptom burden).

    Measured: Up to approximately 21 months

  8. Anti-SYS6010 antibodies (ADA)

    Incidence of SYS6010 anti-drug antibodies

    Measured: Up to approximately 21 months

  9. EGFR protein expression lever (IHC)

    EGFR protein expression assessed by immunohistochemistry (IHC)

    Measured: Up to approximately 21 months

  10. Exploratory Genomic Analysis by Next-Generation Sequencing (NGS)

    Tumor samples will be assessed by next-generation sequencing (NGS) to characterize genomic alterations.

    Measured: Up to approximately 21 months
