Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Consented participants with non-small cell lung cancer, progressing on first line immunotherapy, who are receiving radiotherapy to progressive disease sites, will partake in PET/CT imaging using 89Zr- Df-Crefmirlimab (CD8) and 89Zr -durva tracers. Before radiotherapy (Day 1), a CD8 PET/CT scan will occur, and 89Zr-DF-Crefirmilab (3.0mCi/8mL) will be administered over a 5-10 minute intravenous infusion using a syringe pump (total time will be approximately 30 minutes). After 7 days post radiotherapy, participants will return for their standard of care FDG PET/CT scan and will also be asked to do the CD8 PET/CT scan again. Then after 7 days, participants will be asked to do the 89Zr -durva tracer scan, where a 10mg dose of durvalumab will also be injected through slow intravenous infusion (approximately 30 minutes).

Primary Analysis

The primary objective is to describe the distribution of CD8 ImmunoPEt within tumours at baseline, and after radiotherapy, and 89Zr-durva after radiotherapy.

Quantitative measures on 89Zr-durva PET/CT, FDG PET/CT and 89Zr-durva immunohistochemistry will be summarized.

Correlations between quantitative measures will be expressed as a Pearson/Spearman correlation coefficient depending on distribution of data.

CD8 ImmunoPET and FDG PET/CT pre, and 89Zr-durva PET/CT, CD8 ImmunoPET and FDG PET/CT post- radiotherapy in the following absolute measures of MTV, SUVmax, SUVmean, SUVpeak, and %ID will be summarised. Results will be displayed in graphs.



Secondary analysis

Concordance between FDG, 89Zr-durva, and CD8 ImmunoPET PET/CT alterations over time will be assessed using a weighted kappa coefficient with weights based on quadratic differences.

Associations between intra-treatment response and overall survival (OS) / disease progression free survival (DFS) will be described graphically using Kaplan-Meier product limit curves.

Proportion of patients in which 89Zr-durva and CD8 ImmunoPET PET/CT provides information not seen on FDG-PET or PD-L1 immunohistochemistry performed at baseline and proportion of patients in which additional information from 89Zr-durva PET/CT with the potential to alter management will be described.

Exploratory Analysis

The relationship between changes seen on imaging with 89Zr-durva PET/CT, CD8 ImmunoPET will be qualitatively compared with data from mass cytometry of PBMC, TCR characterization and cytokine profiling

Summary
Brief summary
This study is investigating the activity of an immunotherapy checkpoint called PD-L1 and the activity of the immune T-cells (CD8 T-cells) that kill cancer cells.

In this study, we will test proven and new types of cancer imaging, also called scans. We will test if these scans show us new information about non-small cell lung cancer (NSCLC). We will also test if the information shown on the scan matches information shown by pathology.

Who is it for?
For this study, we need participants aged 18 and over, who have non-small cell lung cancer (NSCLC) who are going to receive radiotherapy treatment. You must have acceptable kidney function and agree to come in for the study follow up assessments. Female participants must either be post-menopausal or have a negative pregnancy test.

Study details

All participants will be asked to undergo a Positron Emission Tomography (PET)/Computed Tomography (CT) with fluoro-deoxyglucose (FDG), which is a standard scan used to detect lung cancer.

PET/CT scanning is achieved by injecting a small amount of radioactive material (called a tracer) into your bloodstream followed by imaging your body by passing you through a PET/CT scanner whilst you lie on your back.

This study is using 2 PET tracers: 89Zr-Df-crefmirlimab (CD8 PET), which shows us where the T-cells are in your body and 89Zr-durvalumab, which is made with an immunotherapy drug that targets the protein PD-L1. PD-L1 is a protein that keeps immune cells from attacking non-harmful cells in the body.

We think that some cancer cells have high amounts of PD-L1 at the beginning of immunotherapy treatment, but that this may change during treatment, allowing the cancer cells to grow. Alternatively, the cancer cells may remain sensitive to durvalumab, but the tumours do not have enough CD8 T-cells to kill the cancer cells.
