[68Ga]Ga-FAPI Total Body PET/CT for Better and Faster Imaging in Cancer

Официальное название

[68Ga]Ga-FAPI PET/CT for Response Evaluation During Immune Checkpoint Inhibitor Therapy in Malignant Melanoma

Обзор

The goal of this clinical trial is to investigate the use of the tracer \[68Ga\]Ga-FAPI-46 for PET/CT-imaging in response evaluation of patients with advanced stage malignant melanoma treated with immune checkpoint inhibitor therapy (ICT). The main question it aims to answer is: • Can \[68Ga\]Ga-FAPI-46 PET/CT improve response evaluation in patients suffering from advanced stage malignant melanoma treated with ICT and potentially serve as a biomarker. Researchers will compare findings on the experimental \[68Ga\]Ga-FAPI-46 PET/CT with findings on standard imaging (\[18F\]FDG PET/CT). Participants will undergo: * Two \[68Ga\]Ga-FAPI-46 PET/CT scans: one before treatment initiation with ICT and one after three months. * Two blood samples * Passive follow-up 6 months after the last scan \[68Ga\]Ga-FAPI-46 PET/CT

Вмешательства

• Препарат [68Ga]Ga-FAPI-46
  Patients undergo two PET/CTs with the experimental tracer \[68Ga\]Ga-FAPI-46 (drug).

Первичные конечные точки

• Changes in FAPI-uptake in malignant lesions on [68Ga]Ga-FAPI-46 PET/CT during ICT [Срок оценки: From enrollment in the study (signed informed consent) to after the second [68Ga]Ga- FAPI PET/CT, estimated time is 3 months.]

Вторичные конечные точки (1)

• Changes in [68Ga]Ga-FAPI-46-uptake during ICT in healthy tissue [Срок оценки: From enrollment in the study (signed informed consent) to the end of the follow-up (6 months after the second [68Ga]Ga-FAPI-46 PET/CT, estimated time in total is 9 months from signed informed consent).]
