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.

RECRUITING[Phase Ib] Objective response rate (ORR) According to response evaluation criteria in solid tumors (RECIST) v1.1 by Investigators (INVs)
ORR is defined as the percentage of participants with DOR of confirmed CR or confirmed PR per RECIST v1.1
Time frame: From the date of first dose until the date of disease progression or withdrawal from study, up to approximately 40 months
[Phase III] Progression-Free Survival (PFS) According to RECIST v1.1 by Independent Review Committee(IRC)
PFS is defined as the time from randomization until the date of objective disease progression or death, whichever occurred first, based on IRC using RECIST v1.1
Time frame: Up to approximately 40 months
[Phase Ib and III] Overall Survival (OS)
Overall Survival is defined as the time from the date of randomization to the date of participant's death due to any cause.
Time frame: Approximately 60 months
[Phase Ib and III] Disease control rate (DCR) According to RECIST v1.1 by INVs
DCR is defined as the percentage of patients who have a best overall response (confirmed CR, PR, or stable disease for at least 6 weeks) based on Investigator's assessment per RECIST v1.1.
Time frame: From the date of first dose until the date of disease progression or withdrawal from study, approximately 40 months.
[Phase Ib and III] Duration of response (DoR) According to RECIST v1.1 by INVs
DoR only applies to participants whose best overall response is CR or PR based on Investigator's assessment per RECIST v1.1. The start date is the date of first documented response of CR or PR (i.e. the start date of observed response, not the date when response was confirmed), and the end date is defined as the date of the first documented progression or death due to underlying disease.
Time frame: From the date of CR, PR until the date of disease progression or death, approximately 40 months.
[Phase Ib and III] Progression-Free Survival (PFS) According to RECIST v1.1 by INVs
PFS is defined as the time from randomization until the date of objective disease progression or death, whichever occurred first, based on IRC using RECIST v1.1
Time frame: Up to approximately 40 months
[Phase III] ORR According to RECIST v1.1 by INVs
ORR is defined as the percentage of participants with BOR of CR or PR per RECIST v1.1
Time frame: From the date of first dose until the date of disease progression or withdrawal from study, up to approximately 40 months
[Phase III] ORR According to RECIST v1.1 by IRC
ORR is defined as the percentage of participants with BOR of CR or PR per RECIST v1.1
Time frame: From the date of first dose until the date of disease progression or withdrawal from study, up to approximately 40 months
[Phase III] DCR According to RECIST v1.1 by IRC
DCR is defined as the percentage of patients who have a best overall response (confirmed CR, PR, or stable disease for at least 6 weeks)
Time frame: From the date of first dose until the date of disease progression or withdrawal from study, approximately 40 months.
[Phase III] DoR According to RECIST v1.1 by IRC
DoR only applies to participants whose best overall response is CR or PR. The start date is the date of first documented response of CR or PR (i.e. the start date of observed response, not the date when response was confirmed), and the end date is defined as the date of the first documented progression or death due to underlying disease.
Time frame: From the date of CR, PR until the date of disease progression or death, approximately 40 months.
[Phase Ib and III] Incidence and severity of treatment-emergent adverse events
Adverse event (assessed according to NCI CTCAE v5.0) is defined as any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.
Time frame: From the date of first dose until 90 days after the final dose. A cycle is 28 days.
[Phase Ib and III] Immunogenicity of HS-20117
Immunogenicity will be measured by the number of participants that are ADA positive.
Time frame: Cycle 1 Day 1: predose through EOT or follow up period (90 days after the last dose).
[Phase Ib] PK parameters: Maximum serum concentration (Cmax) of HS-20117
The Cmax is the maximum observed serum concentration of HS-20117
Time frame: From the date of first dose until 30 days after the final dose. A cycle is 28 days.
[Phase Ib] PK parameters: Trough serum concentration (Ctrough) of HS-20117
Ctrough is the observed serum concentration immediately prior to the next administration
