A Phase Ib Study of Tislelizumab Plus SYS6010 in Immunotherapy-Pretreated Locally Advanced or Metastatic NSCLC (SYS6010)
Introduction: Patients with driver gene-negative non-small cell lung cancer (NSCLC) who experience treatment failure following immune checkpoint inhibitor (ICI) therapy have limited subsequent treatment options, representing an unmet clinical need. EGFR is commonly expressed in EGFR wild-type NSCLC and represents a potential target for therapeutic intervention. Antibody-drug conjugates (ADCs) combine the high targeting specificity of antibodies with the potent cytotoxic effects of payloads. SYS6010 is an EGFR-targeting ADC conjugated to a topoisomerase I inhibitor. Preclinical and clinical studies suggest that the combination of ADCs and ICIs can synergistically enhance anti-tumor efficacy through multiple immunomodulatory mechanisms. Tislelizumab is an approved PD-1 inhibitor for advanced NSCLC. This study aims to evaluate the safety and efficacy of SYS6010 in combination with tislelizumab in patients with driver gene-negative NSCLC who have failed prior PD-1/PD-L1 inhibitor therapy.
Methods: This is an exploratory clinical trial enrolling patients with driver gene-negative NSCLC who have failed prior PD-1 or PD-L1 inhibitor therapy. The primary objective is to evaluate the safety of the combination therapy, with primary endpoints including the incidence, severity, and type of adverse events (AEs) according to NCI-CTCAE v6.0 criteria. Secondary objectives include assessing efficacy (objective response rate [ORR], disease control rate [DCR], duration of response [DOR], progression-free survival [PFS], overall survival [OS]) and exploring the association of potential predictive or prognostic biomarkers (e.g., EGFR and PD-L1 expression levels) with response to study treatment.

Hepatic function: Total bilirubin ≤ 1.5 × upper limit of normal (ULN) (or ≤ 3 × ULN in the presence of liver metastases); aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 × ULN (or ≤ 5.0 × ULN in the presence of liver metastases); albumin ≥ 28 g/L.
Renal function: Serum creatinine ≤ 1.5 × ULN or creatinine clearance ≥ 50 mL/min (calculated using the Cockcroft-Gault formula; see Appendix 3).
Coagulation function: International normalised ratio (INR) and activated partial thromboplastin time (APTT) ≤ 1.5 × ULN.
Subjects with chronic hepatitis B virus (HBV) infection must have HBV-DNA < 1000 IU/mL and be willing to receive antiviral therapy throughout the study period.
Toxicities from prior therapy must have recovered to ≤ Grade 1 (CTCAE v5.0) or to a stable condition per investigator assessment at the time of the first study dose (alopecia and pigmentation excepted).
Subjects of childbearing potential must agree to use highly effective contraceptive methods (including vasectomy, abstinence, etc.; see Appendix 4) throughout the study period (from signing the ICF until 6 months after the last dose of investigational product).
Subjects must be able to communicate well with the investigator and comply with protocol-required follow-up.
