Brief Summary:
This study aims to evaluate the safety and mechanisms of action of the trimodality treatment (radiotherapy, immunotherapy and surgery) in early-stage non-small cell lung cancer. Half of the patients will receive stereotactic ablative radiotherapy followed by 2 cycles of immunotherapy (pembrolizumab); the other half will not receive the immunotherapy treatment. After treatment, both groups will continue treatment according to guidelines and will undergo surgery (lobectomy).

Condition or disease Intervention/treatment Phase
NSCLC, Stage I Radiation: SABR Combination Product: SABR + pembrolizumab Phase 1 Phase 2

Detailed Description:

An open label randomized exploratory study of the safety and mechanisms of action of combined treatment with SBRT and immunotherapy (pembrolizumab, anti-PD1) for early stage NSCLC.

Intervention:

Patients will be randomized between SBRT with or without 2 cycles of pembrolizumab treatment (starting on the first day of radiotherapy). The patients will undergo a lobectomy with hilar and mediastinal lymph node dissection after SBRT +/- pembrolizumab treatment. Translational research to explore the immune mechanism of action will include biological imaging with immuno-PET (positron emission tomography). Expression rates and activation states of immune effector subsets will be assessed in tumor core biopsy specimens, peripheral blood and tumor draining lymph nodes (TDLNs) by means of fine needle aspirates of TDLNs.

Main study parameters/endpoints:

To assess the safety of combined SBRT and pembrolizumab treatment in early stage NSCLC and to identify the immunological mechanism of action.

Arm Intervention/treatment
Active Comparator: SABR

Radiation: SABR
Prior to surgery (lobectomy), patients receive stereotactic ablative radiotherapy.

Active Comparator: SABR + pembrolizumab

Primary Outcome Measures :
  1. Incidence and severity of adverse events in patients treated by combining SBRT and pembrolizumab [ Time Frame: Up to 90 days post-treatment ]
    Safety of the combination of SBRT and pembrolizumab will be assessed by the percentage of ≥3 pneumonitis. When combined SBRT and pembrolizumab treatment results in NCIC-CTC grade ≥3 pneumonitis in ≤10% of patients, the combination is regarded as safe. Serious adverse events will be recorded to assess both incidence and severity.

  7. Immune cell count [ Time Frame: Up to 90 days post-treatment ]
    Cell count of the individual immune cells in tumordraining lymphnodes and non-tumordraining lymphnodes

  8. Analysis of PET data - SUVmax (standardized uptake value) [ Time Frame: Up to 90 days post-treatment ]
    SUVmax will be measured in all tumor lesions, enlarged lymph nodes and liver, kidneys, lungs, spleen and left ventricle of the heart.

  9. Analysis of PET data - SUVpeak (standardized uptake value) [ Time Frame: Up to 90 days post-treatment ]
    SUVpeak will be measured in all tumor lesions, enlarged lymph nodes and liver, kidneys, lungs, spleen and left ventricle of the heart.

  10. Analysis of PET data -SUVmean (standardized uptake value) [ Time Frame: Up to 90 days post-treatment ]
    SUVmean will be measured in all tumor lesions, enlarged lymph nodes and liver, kidneys, lungs, spleen and left ventricle of the heart.

  11. Analysis of CT data - Hounsfield Unit density [ Time Frame: Up to 90 days post-treatment ]
    The pre- and post SBRT +/- pembrolizumab CT scans will be assessed for HU density and f-air values

  12. Analysis of CT data - f-air values [ Time Frame: Up to 90 days post-treatment ]
    The pre- and post SBRT +/- pembrolizumab CT scans will be assessed for and f-air values

  13. Correlation between PET data and Blood + Tissue markers [ Time Frame: Up to 90 days post-treatment ]
    The data of the PET-scan will be analyzed and compared to the blood and tissue samples to find a correlation between findings.

  14. Correlation between tumor uptake of Zr89-pembrolizumab and irAEs [ Time Frame: Up to 90 days post-treatment ]
    SUV are values used to describe PET-data. irAE's are specific adverse events. This outcome aims to correlate the (possible) irAE's with the PET-data.
