Brief Summary:
This study will measure PD-L1 expression in metastatic NSCLC (primary tumour and metastatic lesions) using [99mTc]-NM-01 SPECT/CT and compare to PD-L1 percentage expression determined by immunohistochemistry (IHC).

Condition or disease Intervention/treatment Phase
Non-Small Cell Lung Cancer Diagnostic Test: [99mTc]-NM01 SPECT/CT Phase 2

Detailed Description:
A non-blinded, single centre, single interventional arm Phase II diagnostic imaging study.

Arm Intervention/treatment
Experimental: Metastatic Non-Small Cell Lung Cancer

Subjects with metastatic non-small cell lung cancer will be recruited as per protocol inclusion/exclusion criteria and will undergo [99mTc]-anti-PDL1 single-domain antibody ([99mTc]-NM-01) SPECT/CT imaging.

[99mTc]-NM-01 SPECT/CT images will be compared to immunohistochemistry PD-L1 expression results.

Diagnostic Test: [99mTc]-NM01 SPECT/CT
Technetium-99m radiolabelled anti-PD-L1 single-domain antibody (NM01) single-photon emission computed tomography (SPECT)/computed tomography (CT)

Primary Outcome Measures :
  1. PD-L1 Expression Assessment using [99mTc]-NM-01 SPECT/CT [ Time Frame: Day 0 ]
    To measure PD-L1 expression in NSCLC (primary tumour and metastatic lesions) as assessed using [99mTc]-NM-01 SPECT/CT and compare to PD-L1 expression determined by IHC.

Secondary Outcome Measures :
  1. Safety of [99mTc]-NM-01 SPECT/CT assessed through incidence of Adverse Drug Reactions [ Time Frame: Up to 12 days post-injection ]
    To assess the safety of [99mTc]-NM-01 SPECT/CT scan by observing for Adverse Drug Reactions (ADRs) occurring during the trial.

  2. PD-L1 expression heterogeneity as assessed by [99mTc]-NM-01 SPECT/CT tumour to blood-pool ratios in each lesion [ Time Frame: Day 0 ]
    To measure intra-tumoural heterogeneity in the primary tumour, as well as in individual metastases and inter-tumoural heterogeneity between different disease sites (including different metastatic sites and between primary tumour and its metastases).

Other Outcome Measures:
  1. Exploratory Objectives [ Time Frame: Up to 16 weeks post-injection ]
    To correlate the SPECT/CT PD-L1 assessment with other diagnostic parameters such as blood tumour mutation burden test and to detect the presence of anti-drug antibodies to [99mTc]-NM-01.
