Main objective

Scope: Diagnosis

The overall aim of the study is to evaluate Total Body (TB) positron emission tomography/computed tomography (PET/CT) combined with the tracer [68Ga]Ga-FAPI-46 for response evaluation during immune checkpoint inhibitor therapy (ICT) in patients with advanced stage malignant melanoma.

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 5

  1. Male or female, > 18 years old
  2. Histological verified metastatic or locally advanced malignant melanoma
  3. Visible malignant lesions on [18F]FDG PET/CT or CT
  4. Subjects must be considered medically suitable for ICT (either Pembrolizumab or Ipilimumab+Nivolumab)
  5. Subjects must be able to read and understand the patient information in Danish to give informed consent

Exclusion criteria 5

  1. Ocular or mucosal melanoma
  2. Other concurrent cancer disease
  3. Pregnancy or lactation
  4. Weight more than the maximum limit of a PET/CT-scanner bed (140 kg)
  5. History of allergic reaction due to compounds similar to the chemical composition of [68Ga]Ga-FAPI-46

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 3

  1. Evaluate [68Ga]Ga-FAPI-46-uptake in malignant lesions on [68Ga]Ga-FAPI-46 PET/CT.
  2. Evaluate changes in [68Ga]Ga-FAPI-46-uptake in malignant lesions on [68Ga]Ga-FAPI-46 PET/CT during ICT.
  3. Compare the changes in malignant lesions on [68Ga]Ga-FAPI-46 PET/CT with changes on standard [18F]FDG PET/CT and clinical response during ICT.

Secondary endpoints 5

  1. Changes in [68Ga]Ga-FAPI-46 uptake during ICT in healthy tissue as a predictor of potential side effects.
  2. Compare changes on [68Ga]Ga-FAPI-46 PET/CT in healthy tissue with changes on standard [18F]FDG PET/CT.
  3. Correlation between [68Ga]Ga-FAPI-46-uptake on [68Ga]Ga-FAPI-46 PET/CT and levels of FAP activity biomarkers in serum blood samples.
  4. Correlation between [68Ga]Ga-FAPI-46-uptake on [68Ga]Ga-FAPI-46 PET/CT and levels of other biomarkers (e.g. ECM remodeling biomarkers) in serum blood samples.
  5. Correlation between levels of biomarkers in serum blood samples and treatment outcome.
