Real-World Study of Toripalimab in Extensive-Stage Small Cell Lung Cancer

December 15, 2025 updated by: Zhengfei Zhu, Fudan University

A Prospective, Observational, Multi-Center, Real-World Study of Toripalimab Injection in First-Line Treatment of Extensive-Stage Small Cell Lung Cancer

This is a prospective, observational, multi-center, real-world study evaluating the effectiveness and safety of Toripalimab (a PD-1 inhibitor) as first-line treatment for patients with extensive-stage small cell lung cancer (ES-SCLC). The primary objective is to assess real-world progression-free survival (rwPFS). Secondary objectives include evaluating real-world objective response rate (rwORR), disease control rate (rwDCR), overall survival (rwOS), and safety. Approximately 1200 patients from multiple centers in China will be enrolled and followed according to routine clinical practice. Data will be collected from medical records and follow-up visits.

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Toripalimab group
Drug: Toripalimab
A humanized IgG4 monoclonal antibody against programmed cell death protein 1 (PD-1). The recommended dosage is 240 mg administered intravenously on Day 1 of each 3-week cycle (q3w). Treatment continues until disease progression, unacceptable toxicity, death, withdrawal of consent, or investigator decision. It is used in combination with chemotherapy (etoposide and platinum-based drugs) as per routine clinical practice.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Real-world Progression-Free Survival (rwPFS)
Time Frame: 2 years
The time from the initiation of the first dose until the first documented occurrence of disease progression or death from any cause, whichever occurs first. Patients who do not experience any event during follow-up or study treatment will be censored at the time of their last tumor assessment. Patients who do not have any post-baseline assessment will be censored on the date of enrollment/initiation of medication.
2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Real-world Overall Survival (rwOS)
Time Frame: 2 years
The time from the initiation of the first dose until the documented event of death from any cause. Patients who do not experience the event will be censored at the date of their last known survival. Patients who do not provide any follow-up information will be censored on the date of enrollment/initiation of medication.
2 years
Real-world Objective Response Rate (rwORR)
Time Frame: 2 years
The proportion of patients who achieve a Complete Response (CR) or Partial Response (PR); response is determined by the investigator based on clinician-cited evidence or records without a source of evidence.
2 years
Real-world Disease Control Rate (rwDCR)
Time Frame: 2 years
The proportion of patients who achieve a Complete Response (CR) or Partial Response (PR) or Stable Disease (SD); response is determined by the investigator based on clinician-cited evidence or records without a source of evidence.
2 years
Treatment-related adverse event (TRAE)
Time Frame: 2 years
Including immune-related adverse events (irAEs), particularly Grade ≥3 TRAEs. Monitoring for adverse events will be conducted during the treatment period and until 30 days after the last dose, or until the event resolves or stabilizes.
2 years

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
February 1, 2028

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
