A Study of HS-20117 Combined With Aumolertinib in Participants With Advanced Non-Squamous Non-Small Cell Lung Cancer

HS-20117 is a fully-human EGFR-MET immunoglobulin G1(IgG1)-like bispecific antibody. The purpose of this study is to assess the safety, efficacy, pharmacokinetics and immunogenicity of HS-20117 combined with Aumolertinib in participants with epidermal growth factor receptor (EGFR) mutation (Exon 19 deletions \[Exon 19del\] or Exon 21 L858R substitution) positive, locally advanced or metastatic non-squamous non-small cell lung cancer (NSCLC).

This is a multicenter Phase Ib/III clinical study evaluating the safety, efficacy, pharmacokinetics (PK), and immunogenicity of HS-20117 in combination with aumolertinib in subjects with locally advanced or metastatic non-squamous non-small cell lung cancer (NSCLC). The study is divided into two phases, Phase Ib, a dose expansion study and Phase III, a confirmatory study. In the dose expansion phase (Phase Ib), HS-20117 will first be studied in combination with the standard dose of aumolertinib, to assess the efficacy, safety, tolerability, PK profile, and immunogenicity of HS-20117 in combination with aumolertinib in the target population, as well as to determine the recommended Phase III dose (RP3D). Following confirmation of the safety and efficacy of HS-20117 in combination with aumolertinib and RP3D in Phase Ib, a randomized, active-controlled, open-label, multicenter Phase III study will be initiated to assess the efficacy and safety of HS-20117 in combination with aumolertinib versus aumolertinib in the target population in the confirmatory study phase.
