Safety and Efficacy Study of First-line Treatment With QL1706 Plus Chemotherapy in Extensive-Stage Small Cell Lung Cancer
Study Details
Study Description
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.

Experimental: QL1706+chemotherapy Participants received intravenous infusions of QL1706 5mg/kg in combination with carboplatin to achieve an initial target area under the concentration-time curve (AUC) of 5 mg/mL/min followed by etoposide 100 mg/m^2 on Day 1 of every 21-day cycle for 4-6 cycles. On Days 2 and 3 of every 21-day cycle, etoposide 100 mg/m^2 was administered alone for 4-6 cycles. Thereafter, participants received maintenance QL1706 5mg/kg on Day 1 of every 21-day cycle until progressive disease, intolerable toxicity, withdrawal of consent, death, or study termination by the Sponsor. |
Drug: QL1706
Intravenous infusions of QL1706 5mg/kg on Day 1 of every 21-day cycle.
Drug: Carboplatin
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.
Drug: Etoposide
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.

Outcome Measures
Primary Outcome Measures
- Number of Participants Who Experienced At Least One Adverse Event (AE) [Up to approximately 2 years]
An 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 Outcome Measures
- Percentage of Participants With Objective Response (OR) [Up to approximately 2 years]
The efficacy outcome of objective response rate (ORR) as assessed by the investigator using RECIST v1.1
- Duration of Response (DOR) [Up to approximately 2 years]
The efficacy outcome of DOR as assessed by the investigator using RECIST v1.1
- Duration of Progression-Free Survival (PFS) [Up to approximately 2 years]
The 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 half]
Baseline until death from any cause
