A Study of HS-20093 vs Active Surveillance in Limited-Stage Small Cell Lung Cancer

ARTEMIS-009: A Phase 3, Randomized, Controlled, Multi-center, Open-label Study of HS-20093 Versus Active Surveillance As Consolidation Therapy After Chemoradiotherapy in Subjects With Limited-Stage Small Cell Lung Cancer

This study will evaluate the efficacy, safety and tolerability of HS-20093 compared with active surveillance as consolidation therapy after chemoradiotherapy in participants with limited-stage small cell lung cancer.

Study Overview

• Status: Not yet recruiting
• Conditions: Limited-stage Small-cell Lung Cancer
• Intervention / Treatment: Drug: HS-20093

Detailed Description

This is a randomized, controlled, open-label, multi-center, phase III clinical study to evaluate the efficacy and safety of HS-20093 versus active surveillance as consolidation therapy in participants with limited-stage small cell lung cancer (LS-SCLC) who have not progressed after receiving chemoradiotherapy (CRT).

This study consists of an experimental arm and a control arm. The experimental arm will be administered HS-20093, and the control arm will only receive active surveillance. Efficacy and safety were assessed in both arms by follow-up analyses.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: HS-20093; Patients with LS-SCLC who have not progressed following CRT. Patients in this arm will be administrated HS-20093 intravenously at a dose of 8.0 mg/kg, Q3W continuously until disease progression or until other criteria for discontinuation of treatment are met.	Drug: HS-20093; Subjects in experimental arm will be given HS-20093 intravenously at a dose of 8.0 mg/kg every 3 weeks, until disease progression or until other criteria for treatment discontinuation are met.
No Intervention: Active surveillance; Patients with LS-SCLC who have not progressed following CRT. Patients in this arm will receive active surveillance until disease progression or until other criteria for discontinuation of active surveillance are met.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression-free survival (PFS) According to RECIST v1.1 by Independent Review Committee (IRC)	To assess the efficacy of HS-20093 vs active surveillance in terms of PFS. 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.	Approximately 6 years
Overall survival (OS)	To assess the efficacy of HS-20093 vs active surveillance in terms of OS. Overall Survival is defined as the time from the date of randomization to the date of participant's death due to any cause.	Approximately 6 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
PFS at 12 Months (PFS12) or 18 Months (PFS18) According to RECIST v1.1 by IRC	PFS12 and PFS18 are defined as the progression-free survival at 12 months and 18 months from the date of randomization, respectively, based on IRC using RECIST v1.1.	Approximately 6 years.
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	From the date of randomization until the date of disease progression or withdrawal from study, up to approximately 6 years.
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)	From the date of randomization until the date of disease progression or withdrawal from study, approximately 6 years.
DoR 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, and the end date is defined as the date of the first documented progression or death due to underlying disease.	From the date of CR, PR until the date of disease progression or death, approximately 6 years.
PFS According to RECIST v1.1 by investigators (INVs)	PFS is defined as the time from randomization until the date of objective disease progression or death, whichever occurred first, based on INVs using RECIST v1.1	Approximately 6 years.
PFS12 or PFS18 According to RECIST v1.1 by INVs	PFS12 and PFS18 are defined as the progression-free survival at 12 months and 18 months from the date of randomization, respectively, based on INVs using RECIST v1.1.	Approximately 6 years.
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 by INVs.	From the randomization until the date of disease progression or withdrawal from study, up to approximately 6 years.
DCR According to RECIST v1.1 by INVs	DCR is defined as the percentage of patients who have a best overall response (CR, PR, or stable disease).	From the randomization until the date of disease progression or withdrawal from study, up to approximately 6 years.
DoR According to RECIST v1.1 by INVs	DoR is defined as the percentage of patients who have a best overall response (CR, PR, or stable disease).	From the date of first dose until the date of disease progression or withdrawal from study, up to approximately 6 years.
Proportion of patients alive at 24 months (OS24) or 36 months (OS36)	OS24 and OS36 are defined as the proportion of patients alive at 24 months and 36 months from the date of randomization, respectively, based on INVs using RECIST v1.1.	Approximately 6 years.
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 without regard to possibility of causal relationship.	From the date of first dose until 90 days after the final dose. A cycle is 21 days.
