Development and Application of a Thrombosis Risk Prediction Model in Lung Cancer Patients Treated With Immune Checkpoint Inhibitors

April 26, 2026 updated by: Beijing Chao Yang Hospital

The purpose of this observational study is to explore the incidence, risk factors, and relationship with therapeutic outcomes of VTE (venous thromboembolism) and ATE (arterial thromboembolism) associated with immune checkpoint inhibitors (ICIs) therapy. The primary questions it aims to address are:

  1. What is the real-world incidence of VTE/ATE in lung cancer patients receiving immune checkpoint inhibitors?
  2. What are the risk factors and biomarkers for VTE/ATE in lung cancer patients receiving immune checkpoint inhibitors?
  3. What is the impact of VTE/ATE on the prognosis of lung cancer patients receiving immune checkpoint inhibitors?

Researchers will compare the characteristics and biomarkers of patients with and without ICI-associated VTE/ATE to identify novel specific biomarkers for thrombotic events. Furthermore, they will construct a risk assessment model for thrombotic events to provide guidance for precision prevention and treatment in clinical practice.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Adult patients with histopathologically confirmed lung cancer who were treated with immune checkpoint inhibitors between January 1, 2019, and December 31, 2026.

Description

Inclusion Criteria:

  • Age ≥18 years
  • Histopathologically confirmed lung cancer diagnosis at enrollment
  • Received at least one dose of a China-approved lung cancer immune checkpoint inhibitor

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
Immune checkpoint inhibitor-associated venous thromboembolism/arterial thromboembolism
Time Frame: Begin on the date of the first ICI dose and end upon death, initiation of subsequent systemic anticancer therapy other than ICI, or 3 months after the last ICI cycle, whichever comes first, assessed up to 96 months.
From the administration of the first dose of immune checkpoint inhibitors until death, initiation of subsequent systemic anticancer therapy other than ICI, or 3 months after the last ICI cycle, symptomatic and incidentally detected arterial thromboembolism and venous thromboembolism events that occur during this period are included.
Begin on the date of the first ICI dose and end upon death, initiation of subsequent systemic anticancer therapy other than ICI, or 3 months after the last ICI cycle, whichever comes first, assessed up to 96 months.

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
Progression-free survival
Time Frame: From the date of the administration of the first dose of immune checkpoint inhibitors until the date of disease progression, death from any cause, or the cutoff date, whichever comes first, assessed up to 96 months.
Progression-Free Survival refers to the time from the start of immune checkpoint inhibitor therapy until the disease progresses or the patient dies, whichever occurs first.
From the date of the administration of the first dose of immune checkpoint inhibitors until the date of disease progression, death from any cause, or the cutoff date, whichever comes first, assessed up to 96 months.
Overall survival
Time Frame: From the date of the administration of the first dose of immune checkpoint inhibitors until the date of death from any cause, or the cutoff date, whichever comes first, assessed up to 96 months.
Overall survival refers to the time from the start of immune checkpoint inhibitor therapy until the patient dies or the cutoff date, whichever occurs first."
From the date of the administration of the first dose of immune checkpoint inhibitors until the date of death from any cause, or the cutoff date, whichever comes first, assessed up to 96 months.
Objective response rate
Time Frame: From the date of the first dose of immune checkpoint inhibitors until the best efficacy is achieved, assessed up to 96 months.
Objective Response Rate (ORR) refers to the proportion of patients who experience a confirmed reduction in tumor size or complete disappearance of the tumor, as assessed by standard criteria such as RECIST (Response Evaluation Criteria in Solid Tumors). It includes both complete responses (CR) and partial responses (PR) and is typically reported as a percentage of the total treated population.
From the date of the first dose of immune checkpoint inhibitors until the best efficacy is achieved, assessed up to 96 months.
