Adjuvant Chemotherapy in Patients With High Risk Stage I Non-squamous Non-Small Cell Lung Cancer


The optimal treatment for stage I non-small cell lung cancer (NSCLC) remains controversial. Radiographic surveillance alone has been recommended for stage I patients after the tumor is removed surgically from the lung, and this standard has been based on the fact that no previous clinical trial has demonstrated a benefit for stage I NSCLC patients who receive post-operative chemotherapy. These patients, however, have a substantial risk of death within five years after operation, ranging from approximately 30% to 45%, largely due to metastatic disease that is present immediately after surgery but that is undetectable by conventional methods. Some leading organizations therefore currently recommend post-operative chemotherapy as an alternative standard of care in stage I NSCLC patients who are considered to be at particularly high-risk. Up until now, however, there has not been a well-validated means to identify stage I NSCLC patients at high risk of death within five years after operation. A new prognostic tool, the Pervenio™ Lung RS Assay, which has been validated and definitively demonstrated in large scale studies to identify high-risk stage I patients with non-squamous NSCLC, is now available to all clinicians through a CLIA-certified laboratory. It is therefore now possible to compare the outcomes of patients randomly assigned to one or the other of these competing standards of care.

Full Title of Study: “A Randomized Prospective Trial of Adjuvant Chemotherapy in Patients With Completely Resected Stage I Non-Squamous Non-Small Cell Lung Cancer Identified as High Risk by the Pervenio™ Lung RS Assay”

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: April 2021


  • Drug: Adjuvant Chemotherapy
  • Other: Radiographic surveillance
    • Serial radiographic surveillance is a current standard of care for stage I lung cancer
  • Other: Pervenio™ Lung RS Assay
    • This CLIA-approved assay is a standard tool that is now available to all clinicians to improve the prognostic evaluation of patients after resection of early stage non-squamous NSCLC. It will be performed on tumor specimens for patients who are potentially eligible for this study. Patients identified through the assay as high-risk will be randomized to either adjuvant chemotherapy or observation.

Arms, Groups and Cohorts

  • Active Comparator: Observation
    • Post-operative observation of stage I non-small cell lunger cancer with Radiographic Surveillance is a current standard of care. Patients identified as high-risk by the Pervenio™ Lung RS Assay will be randomized either to this arm or the Adjuvant Chemotherapy Arm.
  • Active Comparator: Adjuvant Chemotherapy
    • Adjuvant Chemotherapy is a current standard of care for high-risk stage I non-small cell lung cancer. Patients identified as high-risk by the Pervenio™ Lung RS Assay will be randomized either to this arm or the Observation Arm.
