PD-L1 Expression in Cancer (PECan Study).

Get Involved

PD-L1 Expression in Cancer (PECan Study).

Study Purpose

Measurement of PD-L1 expression in cancer to monitor treatment response. A prospective non-blinded, single centre, single interventional arm diagnostic imaging study. To determine the baseline level and variability within and between patients and tumour types of PD-L1 expression in melanoma and non-small cell lung cancer in immunotherapy naïve patients using [99mTc]-anti-PD-L1 SPECT/CT and immunohistochemistry.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years and Over
Gender	All

- Willingness and ability to comply with scheduled study visits and tests.

Exclusion Criteria:

- Pregnant or lactating women.

- Concomitant uncontrolled medical conditions.

- Patients likely to require palliative radiotherapy within the first 12 weeks of treatment or radiotherapy to target lesion(s) received within preceding 42 days.

- More than 3 months between IHC PDL1 and study recruitment.

- Patients who have received other systemic anti-cancer therapy within preceding 14 days.

- Prognosis less than 3 months.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT04436406
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	N/A
Lead Sponsor The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.	Guy's and St Thomas' NHS Foundation Trust

Additional Details

Using [99mTc]-labeled anti-PD-L1 single-domain antibody, this study aims to prospectively measure changes in PD-L1 expression determined with SPECT/CT imaging and correlate these changes with response to anti-PD(L)1 immunotherapy.

Arms & Interventions

Arms

Experimental: Advanced malignant disease (non-small cell lung cancer or malignant melanoma)

Group 1: Participants with non-small cell lung cancer (NSCLC) as per inclusion/exclusion criteria undergo baseline PD-L1 expression testing by immunohistochemistry and [99m-Tc]-anti-PD-L1 single-domain antibody SPECT/CT imaging at 0 and 9 weeks. FDG-PET/CT is also performed at baseline (0) and first follow-up (9) weeks scans, in addition to standard CT clinical imaging at 0, 9 and 18 weeks. Group 2: Participants with malignant melanoma (MM) as per inclusion/exclusion criteria undergo baseline PD-L1 expression testing by immunohistochemistry and [99m-Tc]-anti-PD-L1 single-domain antibody SPECT/CT imaging at 0 and 12 weeks. FDG-PET/CT is also performed as standard clinical imaging at baseline (0), first follow-up (12) weeks and 24 weeks.

Interventions

Diagnostic Test: - [99mTc]-NM-01 SPECT/CT

Technetium labelled anti-PD-L1 single-domain antibody (NM-01) single-photon emission computed tomography (SPECT)/CT
