Conditions

Extensive-stage Small-cell Lung Cancer

Brief summary

This is an open label, phase 2 clinical study to evaluate the safety, tolerability, efficacy, pharmacokinetic (PK) profile, and immunogenicity of QL1706 plus carboplatin and etoposide as first-line therapy in patients with extensive-stage small cell lung cancer.

Interventions

DRUGQL1706

Intravenous infusions of QL1706 5mg/kg on Day 1 of every 21-day cycle.

DRUGCarboplatin

Carboplatin intravenous infusion to achieve an initial target AUC of 5 mg/mL/min was administered on Day 1 of each 21-day cycle for 4-6 cycles.

DRUGEtoposide

Etoposide intravenous infusion was administered at a dose of 100 mg/m\^2 on Days 1, 2, and 3 of each 21-day cycle for 4-6 cycles.

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants Who Experienced At Least One Adverse Event (AE)Up to approximately 2 yearsAn AE was defined as any untoward medical occurrence in a participant administered a study treatment and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the study treatment or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that is temporally associated with the use of study treatment, is also an AE. The number of all participants who experienced at least one AE is presented.

Secondary

MeasureTime frameDescription
Percentage of Participants With Objective Response (OR)Up to approximately 2 yearsThe efficacy outcome of objective response rate (ORR) as assessed by the investigator using RECIST v1.1
Duration of Response (DOR)Up to approximately 2 yearsThe efficacy outcome of DOR as assessed by the investigator using RECIST v1.1
Duration of Progression-Free Survival (PFS)Up to approximately 2 yearsThe efficacy outcome of PFS as assessed by the investigator using RECIST v1.1
Duration of Overall Survival (OS)Up to approximately 2 years and a halfBaseline until death from any cause
