An Observational Clinical Study of Stereotactic Radiotherapy for Advanced Non-Small Cell Lung Cancer With Stable Disease After PD-1 Inhibitor Treatment

July 11, 2025 updated by: Jianguo Sun, Xinqiao Hospital of Chongqing

An Observational Clinical Study of Increasing Stereotactic Radiotherapy in Patients With Advanced Non-small Cell Lung Cancer After Treatment With PD-1 Inhibitors And Evaluation of Stable Disease

After the treatment of advanced non-small cell lung cancer with immune checkpoint inhibitor PD-1/PD-L1 monoclonal antibody, if the treatment response of complete response (CR) or partial response (PR) can be achieved in the early stage, the patients are expected to obtain a better long-term survival rate. Radiotherapy can synergistically improve the effect of immunotherapy. Therefore, we propose a hypothesis: in patients with advanced lung cancer, if only stable disease (SD) is achieved after PD-1 antibody immunotherapy in the early stage, by increasing the stereotactic radiotherapy (SBRT) for primary or metastatic lesions, in order to improve the mechanism of tumor antigen release, promote the activation and activation of effector T cells, and increase the sensitivity of immunotherapy, so as to achieve the goal of early improvement of objective remission rate (ORR). It is expected to improve the long-term survival rate of patients.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

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

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

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
objective response rate (ORR)
Time Frame: 2 year
The proportion of patients whose tumors shrink to a certain amount and remain for a certain period of time, including cases of complete response and partial response.

Study Start (Actual)

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.
