A Study of Targeted Post-Surgery Radiation Therapy for Non-Small Cell Lung Cancer With Remaining Lymph Node Cancer After Treatment

August 4, 2026 updated by: Alliance for Clinical Trials in Oncology

Involved-Station, Intensity-Modulated Post-Operative Radiation Therapy (I²-PORT) for Resected Non-Small Cell Lung Cancer With Residual Mediastinal Adenopathy After Neoadjuvant Therapy (ypN2)

This phase II trial compares the effect of intensity-modulated post-operative radiation therapy (I²-PORT) followed by standard of care therapy (chemotherapy or immunotherapy) to standard of care therapy alone in treating patients with non-small cell lung cancer (NSCLC) who have remaining lymph node cancer after surgery. Radiation therapy uses high-energy X-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Intensity-modulated radiation therapy is a type of 3-dimensional radiation therapy that uses computer-generated images to show the size and shape of the tumor. Thin beams of radiation of different intensities are aimed at the tumor from many angles. This type of radiation therapy reduces the damage to healthy tissue near the tumor. Chemotherapy drugs work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Adding I²-PORT radiation therapy to standard therapy may be more effective than standard therapy alone in reducing the risk of cancer returning in those who have undergone surgery for NSCLC.

Detailed Description

PRIMARY OBJECTIVES:

I. To assess whether intensity-modulated post-operative radiation therapy (I²-PORT) improves disease-free survival (DFS) of patients with R0 resected ypN2 NSCLC compared to standard of care (SOC).

II. To assess whether I²-PORT does not unacceptably increase (by ≥ 6.5 percentage points) the rate of severe (grade ≥ 3 per Common Terminology Criteria for Adverse Events [CTCAE] version [v] 5) late cardiopulmonary toxicity compared to SOC.

SECONDARY OBJECTIVES:

I. 5-year DFS, 2- and 5-year overall survival (OS). II. Local versus (vs.) regional control, rate of distant metastases. III. Acute and late adverse events (AE) rates of specific cardiac, pulmonary, and other toxicities, per CTCAE version 5.0.

IV. Rates of non-mild, moderate, or severe-very severe symptoms per Patient Reported Outcomes - Common Terminology Criteria for Adverse Events (PRO-CTCAE), particularly terms related to cardiopulmonary toxicities, e.g., pain, shortness of breath, cough, wheezing, and heart palpitations.

V. Subset analyses by single vs. multi-station N2 and by adequacy of surgical nodal evaluation.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive SOC chemotherapy or immunotherapy on study. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT) and/or magnetic resonance imaging (MRI), fludeoxyglucose-positron emission tomography (FDG-PET), and blood sample collection throughout the study.

ARM II: Patients undergo I²-PORT once daily (QD) Monday through Friday over 15-25 fractions over 5-6 weeks, starting 4-12 weeks after surgery. Radiation simulation should be performed within 21 days of starting I²-PORT. Starting 1-42 days after completion of I²-PORT, patients receive SOC chemotherapy or immunotherapy on the study. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients also undergo CT and/or MRI, FDG-PET, and blood sample collection throughout the study.

After completion of study treatment, patients are followed up every 3 months for 2 years, and then every 6 months for 3 years.

  • Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase [SGPT]) ≤ 5 x upper limit of normal (ULN)
  • Not pregnant, because this study involves radiation therapy, which has known genotoxic, mutagenic and teratogenic effects. Therefore, for women of childbearing potential only, a negative urine or serum pregnancy test done ≤ 7 days prior to registration is required
  • Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
  • Cardiac function: Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better
  • No idiopathic pulmonary fibrosis requiring anti-fibrotic medication: Patients with idiopathic pulmonary fibrosis or inflammatory/interstitial lung disease compromising pulmonary function or requiring ongoing treatment with nintedanib, pirfenidone, or other anti-fibrotic drug are excluded
  • HIV-infected patients on effective anti-retroviral therapy with an undetectable viral load within 6 months are eligible for this trial

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Disease-free survival (DFS)
Time Frame: Time from the date of randomization to the date of earliest disease recurrence/progression or deaths of all causes, assessed up to 5 years
DFS will be analyzed using the Kaplan-Meier methodology and compared between Arm 2 and Arm 1 using a log-rank test stratified by randomization factors. The median DFS for each treatment group will be estimated, and its 80% and 90% confidence intervals will be calculated using the Kaplan-Meier estimator. Additionally, the 24-month DFS rate for each treatment arm, along with its confidence intervals, will be calculated.
Time from the date of randomization to the date of earliest disease recurrence/progression or deaths of all causes, assessed up to 5 years
Incidence of late grade ≥ 3 cardiopulmonary toxicities
Time Frame: Between 3 and 24 months after protocol therapy
Will be assessed according to the Common Terminology Criteria for Adverse Events version 5.0. Will be estimated for each treatment group and the difference between the two treatment groups. The confidence intervals of the rate difference at 80% and 90% significance levels will be estimated using the Miettinen-Nurminen method.
Between 3 and 24 months after protocol therapy

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
5-year DFS
Time Frame: Time from the date of randomization to the date of earliest disease recurrence/progression or deaths of all causes, assessed up to 5 years
DFS will be analyzed using the Kaplan-Meier methodology and compared between Arm 2 and Arm 1
Time from the date of randomization to the date of earliest disease recurrence/progression or deaths of all causes, assessed up to 5 years
2-year overall survival (OS)
Time Frame: Time from the date of randomization to death from all causes, assessed up to 2 years
Will be analyzed using the Kaplan-Meier methodology and compared between Arm 2 and Arm 1 using a log-rank test stratified by randomization factors. Multivariable Cox models will evaluate the treatment effect on survival time and its interaction with baseline covariates, including stage, pre-treatment, histology, and performance status.
Time from the date of randomization to death from all causes, assessed up to 2 years
5-year OS
Time Frame: Time from the date of randomization to death from all causes, assessed up to 5 years Symptomatic skeletal event free survival (SSE-FS)
Will be analyzed using the Kaplan-Meier methodology and compared between Arm 2 and Arm 1 using a log-rank test stratified by randomization factors. Multivariable Cox models will evaluate the treatment effect on survival time and its interaction with baseline covariates, including stage, pre-treatment, histology, and performance status.
Time from the date of randomization to death from all causes, assessed up to 5 years Symptomatic skeletal event free survival (SSE-FS)
Patient-reported symptoms
Time Frame: up to 5 years
Will be assessed using Patient Reported Outcomes - Common Terminology Criteria for Adverse Events and will be evaluated for between-arm differences in proportions of patients with a maximum post-baseline score greater than 0 using Fisher's exact or chi-square test.
up to 5 years
