Clinical Trial Summary

This study aims to determine the feasibility of non-invasive quantitative PD-L1 measurement using [a novel PD-L1 positron emission tomography (PET) tracer and perform immunohistochemistry based measurement of PD-L1 levels within resected lesions in head and neck cancer and brain metastases.

Description:

This study aims to validate a non-invasive quantitative imaging method of whole tumors using a novel PD-L1 positron emission tomography (PET) tracer in patients with head and neck cancer who undergo resection of primary tumor and locoregional lymph node metastases thus providing an excellent model to perform correlative studies with immunohistochemistry (IHC).

The investigators will extend the study to patients with brain metastases because there is a critical need for a non-invasive test for PD-L1 in this population, as biopsy of these lesions is rare.

In this study, the investigators will image patients with brain metastases, which are predominantly from lung cancer and melanoma, that are planned to undergo biopsy. The ultimate goal of this research is to validate quantitative PD-L1 PET imaging in determining PD-L1 expression within primary and metastatic cancer without the need for biopsy and identify parameters of PD-L1 quantitative PET that will allow its translation into clinical practice. This method can then be used to determine which patients may benefit from immunotherapy.

The primary objective of this study aims to test the difference in non-invasive quantitative PD-L1 PET measures (VT) of lesions between different groups of PD-L1 levels (PD-L1 ≥90% vs <1%) in head and neck cancer primary lesions.

Secondary objectives:

1. To establish lesion level association between immunohistochemistry measures of PD-L1 levels within primary head and neck cancer lesions (as the outcome) and PD-L1 PET measures (VT);

2. To establish lesion level association between immunohistochemistry measures of PD-L1 levels within locoregional metastases within the neck and resected normal lymph nodes (as the outcome) and PD-L1 PET measures (VT).

3. To establish lesion level association between the degree of tumor inflammatory cell infiltration on IHC in primary head and neck squamous cell carcinoma (SCC) lesions (as the outcome) and PD-L1 PET measures (VT);

4. To establish lesion level association between the degree of tumor inflammatory cell infiltration on IHC in metastatic head and neck SCC lesion (as the outcomes) and PD-L1 PET measures (VT).

Tertiary objective:

To establish lesion level correlation of IHC measures of total/tumor/inflammatory cell PD-L1 levels to PD-L1 (VT) on PET in brain metastases

Intervention

Drug:
• adnectin 18F-BMS-986192 Head and Neck Cancer
Head and Neck Cancer: PET imaging will be performed after initial diagnosis and within 2 weeks of MRI or CT of the neck done as standard of care. MRI will include T1 weighted pre and post gadolinium spin echo, diffusion weighted imaging, and T2 weighted imaging. CT of the head and neck with contrast will be performed per standard clinical protocol. Patients will get one intravenous line and one radial artery line placed prior to imaging and up to 5.5mCi (204MBq) of [18F] PDL192 tracer will be administered intravenously, as a bolus, once the patient is positioned on the scanner. 42 PET data will be acquired at single bed position and in list mode for 120 min after the start of tracer administration. Samples will be drawn from radial artery line.
• adnectin 18F-BMS-986192 Brain Metastases
Brain Metastases: Recruited patients will undergo standard clinical MRI within 2 weeks prior to PET, including T1 weighted pre- and post-gadolinium spin-echo and gradient-echo imaging, diffusion weighted imaging, susceptibility weighted imaging (2D SWI), T2 weighted imaging, 3D FLAIR, and combined DCE and dynamic susceptibility contrast (DSC) perfusion (DCE perfusion will be performed first, DSC perfusion will utilize T2 spin echo images). DCE perfusion will be processed on syngo Tissue 4D software (Siemens). DSC perfusion will be processed with syngo MR Perfusion Engine (Siemens). Patients will get one intravenous line and one radial artery line placed prior to imaging and up to 5.5mCi (204MBq) of [18F] PDL192 tracer will be administered intravenously, as a bolus, once the patient is positioned on the scanner. 42 PET data will be acquired at single bed position and in list mode for 120 min after the start of tracer administration.
