NCT05157659

Brief Summary

\[18F\]F-AraG is a promising tracer to image activated T-cells with positron emission tomography (PET). The aim of the ATTAIN trial is to investigate the pharmacokinetic characteristics of this novel tracer by performing a full kinetic modelling, assess test-retest (TRT) variability and to correlate the tumor tracer uptake with the pathological assessment.

Outcome Measures

Primary Outcomes (2)

  • Full kinetic modelling

    To perform full kinetic modeling of \[18F\]F-AraG for the uptake in tumor lesions and healthy organs (e.g. spleen) by exploring different kinetic models and outcome measures as well as its test-retest (TRT) variability to guide the selection of an optimal PET pharmacokinetic model.

    six months

  • Correlation with number of CD8 T-cell

    To correlate the relationship between the tumor uptake of \[18F\]F-AraG and the number of CD8 T-cells amongst others as measured by Immunohistochemistry (IHC) and gene expression.

    six months

Secondary Outcomes (1)

  • Correlation with [18F]-FDG PET uptake

    six months

Other Outcomes (1)

  • Correlation with immune profile of PBMCs

    one year

Study Arms (1)

[18F]F-AraG PET procedures

EXPERIMENTAL

Within one week prior to resection two \[18F\]F-AraG PET-scans will be performed.

Diagnostic Test: [18F]F-AraG PET-scan

Interventions

[18F]F-AraG PET-scanDIAGNOSTIC_TEST

\[18F\]F-AraG PET scans are performed to assess the accumulation of activated T-cells in the tumour and healthy tissue.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically confirmed NSCLC, a histological biopsy is mandatory.
  • Patients that are resectable upfront as per multidisciplinary tumor board evaluation.
  • Be willing and able to provide written informed consent for the trial.
  • Be above 18 years of age on day of signing informed consent.
  • Have a performance status of 0-1 on the ECOG Performance Scale at screening.

You may not qualify if:

  • Subjects with a condition requiring systemic treatment with either corticosteroids (\> 10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days of screening. Inhaled or topical steroids, and adrenal replacement steroid \>10 mg daily prednisone equivalent, are permitted in the absence of active autoimmune disease.
  • Psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
  • Patient is pregnant or breastfeeding or expecting to conceive within the projected duration of the trial, starting with the screening visit through 12 weeks after the last \[18F\]F-AraG PET scan.
