A Study of Sintilimab Compared With Docetaxel or Pemetrexed as Second-line Treatment for Patients With Stage IV Nonsquamous Non-small Cell Lung Cancer After Failure With Platinum-Containing Chemotherapy

Phase 2

• Conditions: Nonsquamous Non-Small Cell Lung Cancer
• Interventions: Drug: Docetaxel; Drug: Sintilimab; Drug: Pemetrexed

• Registration Number: NCT03830411
• Lead Sponsor: Xin-Hua Xu

Brief Summary

This prospective, single-center, randomized, controlled study will evaluate the efficacy and safety of sintilimab compared with docetaxel or pemetrexed as second-line treatment for patients with stage IV nonsquamous non-small cell lung cancer with wild-type EGFR after failure with platinum-containing chemotherapy. Treatment may continue as long as participants are experiencing clinical benefit as assessed by the investigator, i.e., in the absence of unacceptable toxicity or symptomatic deterioration attributed to disease progression.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: PARALLEL

Arm && Interventions

Group	Intervention	Description
Arm B: Chemotherapy (Docetaxel or Pemetrexed)	Docetaxel	Participants randomized to the chemotherapy arm will receive docetaxel or pemetrexed until disease progression per standard RECIST v1.1 or unacceptable toxicity.
Arm A: Sintilimab	Sintilimab	Participants will receive Sintilimab as long as they continue to experience clinical benefit in the opinion of the investigator until unacceptable toxicity or symptomatic deterioration attributed to disease progression as determined by the investigator.
Arm B: Chemotherapy (Docetaxel or Pemetrexed)	Pemetrexed	Participants randomized to the chemotherapy arm will receive docetaxel or pemetrexed until disease progression per standard RECIST v1.1 or unacceptable toxicity.

Primary Outcome Measures

Name	Time	Method
Overall Survival (OS)	Approximately 21 months	Overall Survival (OS) was defined as the time from the date of randomization to the date of death due to any cause. Data for participants who were not reported as dead at the time of analysis was censored at the date when they were last known to be alive.

Secondary Outcome Measures

Name	Time	Method
Objective Response Rate (ORR)	Approximately 21 months	ORR was defined as the percentage of participants with confirmed objective tumor response, complete response (CR) or partial response (PR), as determined by investigator using RECIST v1.1 criteria.
Progression-free survival (PFS)	Approximately 21 months	PFS was defined as the time between the date of randomization and the date of first documented disease progression or death, whichever occurs first. Disease progression was determined based on investigator assessment using response evaluation criteria In solid tumors (RECIST) v1.1.
Duration of response (DOR)	Approximately 21 months	DOR was defined as the duration from the first tumor assessment that supports the participant's objective response (CR or PR, whichever is first recorded) to disease progression or death due to any cause, whichever occurs first.
Emergence of adverse events(AEs)	Approximately 21 months	AEs graded using CTCAE (Version 4.0) criteria.
