Spots Global Cancer Trial Database for Bioimaging Study of 89Zr-M7824 in NSCLC

Study Description

Brief Summary: This is a bioimaging study of 89Zr-M7824 PET scans in patients with advanced or metastatic non-small cell lung cancer who will be receiving M7824 alone or with standard of care chemotherapy. M7824 is a bifunctional fusion protein that combines an anti-PD-L1 antibody and the extracellular domain of TGFβ receptor II (TGFβRII) as a TGFβ neutralizing 'trap', into a single molecule.

Detailed Description: Immune checkpoint inhibitors have shown improved treatment outcome in patients with NSCLC; however, there is room to further improve benefits. A novel agent such as M7824, a fusion protein which targets the tumor microenvironment where it blocks both the cell intrinsic PD-L1/PD-1 interaction and the immunosuppressive TGFβ, is hypothesized to be more effective than agents that target only a single pathway. This study aims to investigate functional imaging with 89Zr-M7824 to characterize the biodistribution of M7824 to support its clinical development. In Part A, we will evaluate the biodistribution of zirconium-89 (89Zr) labelled M7824 in a small cohort of lung cancer patients unselected for PD-L1 status (n=3). In particular, we will examine the ability of 89Zr-M7824 to detect and quantitate intra-tumoural PD-L1 expression and correlate this with PD-L1 assessment in archival tissue. Based on this, Part B will gather additional data about the biodistribution of 89Zr-M7824 in an additional 9 patients. The requirement for patients in Part B to have high levels of PD-L1 positive cells in tumours based on a fresh biopsy or archival tissue at study entry will be informed by the data generated in Part A. Safety will be formally assessed also as a secondary endpoint at the end of Part A of the study and addressed if necessary. After completion of 2 imaging cycles, patients who do not show complete response to M7824 monotherapy after 3 therapeutic doses of M7824 may be transitioned to M7824/chemotherapy combination
