NCT03584334

Prospective non-randomized, multi-center, diagnostic performance study of 18FDG PET for identification of early tumor escape to immunotherapy in patients with unresectable melanoma or Broncho-Pulmonary Carcinoma No to Advanced or Metastatic Small Cells

The hypothesis of this diagnostic performance study is that, for patients treated for immunotherapy-treated melanoma or NSCLC, some metabolic parameters of the 18FDG dual-point PET scan distinguish inflammatory pseudo-progression from tumor progression true and thus improve the evaluation of tumor response to immunotherapy

NCT05289193

CD8+ Cell Imaging During Neoadjuvant ImmunoTherapy (The C-IT Neo Trial)

Combination treatment with nivolumab and ipilimumab before surgery may help people with melanoma because the drugs are designed to help the immune system target and destroy cancer cells (immunotherapy), which may shrink the cancer and prevent recurrence after surgery. Treatment given before surgery is called neoadjuvant therapy. The purpose of this study is to find out whether neoadjuvant therapy with nivolumab and ipilimumab can kill melanoma tumors before surgery and prevent disease from coming back after surgery. This study also explores a new, experimental PET scan that images the immune system to see if it is related to treatment outcomes.

Correlation Between Early Interval 18F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography (PET/CT) and Circulating Tumor DNA (ctDNA) in Advanced Melanoma Patients Treated With Immune Checkpoint Inhibitors

The purpose of this research study is to determine if analysis of PET/CT scans and testing of blood samples in people with melanoma that has spread in their body can help researchers determine which patients are more or less likely to respond to immunotherapy and are more or less likely to have side effects. 24 participants will be enrolled and be on study until approximately 4 weeks after their first dose of Immune Checkpoint Inhibitor therapy.

NCT05068102

An Open Label Phase I PET Imaging Study to Investigate the Bio-distribution and Tumor Uptake of [89Zr]Zr-BI 765063 and [89Zr]Zr-BI 770371 in Patients With Head and Neck Squamous Cell Carcinoma, Non-small Cell Lung Cancer or Melanoma Who Are Treated With Ezabenlimab

The purpose of this study is to find out how 2 medicines called BI 765063 and BI 770371 are taken up in the tumours and how they get distributed in the body. In addition to BI 765063 or BI 770371, participants also receive ezabenlimab. BI 765063, BI 770371 and ezabenlimab are antibodies that may help the immune system fight cancer. Such therapies are also called immune checkpoint inhibitors. Participants get either BI 765063 or BI 770371 in combination with ezabenlimab as an infusion into a vein every 3 weeks. In the first weeks, doctors check how BI 765063 and BI 770371 are taken up in tumours. To do so, the doctors use imaging methods (PET/CT scans). For this, participants get BI 765063 or BI 770371 injected in a labelled form up to 2 times.

NCT05645484

The Prognostic Value of 18F-PFPN PET Imaging in Patients With Malignant Melanoma

This is a monocentric prospective study. This study aims to investigate the prognostic value of the novel melanin-targeted imaging modality 18F-PFPN PET in patients with melanoma and seek independent prognostic factors for progression-free survival (PFS) and overall survival (OS). The patients with clinically highly suspected or confirmed melanoma who underwent 18F-PFPN and 18F-FDG PET scans will be enrolled consecutively. Patients' PET images, clinical characteristics, and follow-up information will be collected for prognostic analyses. This study plans to set the sample size as 100 cases.

NCT04459273

PET Biodistribution Study of 68Ga-FAPI-46 in Patients With Different Malignancies: An Exploratory Biodistribution Study With Histopathology Validation

This exploratory study investigates how an imaging technique called 68Ga-FAPi-46 PET/CT can determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues in patients with cancer. Because some cancers take up 68Ga-FAPi-46 it can be seen with PET. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors (cancer associated fibroblasts). The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers.

NCT04663126

Pilot Study to Test the Feasibility of IV Injected Tc-99m-tilmanocept for Imaging of M2-like Tumour Associated Macrophages in Metastatic Melanoma

This study in 20 patients is designed as a monocentric, open-label and uncontrolled, exploratory pilot study. Patients diagnosed with advanced melanoma (stage III-IV) and scheduled for anti-PD-1 immunotherapy will be recruited for this project. Patients will receive IV 250 µg Tilmanocept, labelled with 370 MBq of Tc-99m (bolus injection) according to the Navidea's protocol in our GMP certified radiopharmaceutical unit, before the first cycle of clinically scheduled immunotherapy. Scintigraphy images will be acquired dynamically from time of injection to +30 minutes. Quantitative SPECT/CT (xSPECT/CT, Siemens Symbia Intevo, Erlangen, Germany) imaging will be performed up to 1 hour p.i. to evaluate hyperaemia, and up to 3 hours p.i. to image and measure the CD206 receptor uptake. The data of the scans will be compared to immunohistochemistry results from biopsy staining for TAMs and M2-like TAMs and retrospectively with response to the immunotherapy to determine any correlation between M2-like TAMs and treatment response. For the planned retrospective comparison we will use the FDG - PET/CT data that is done after the immunotherapy as standard of care. We will analyse the lesion size and FDG - uptake in standard of care PET/CT of CD206+ and CD206 negative lesions in Tilmanocept SPECT/CT before and after immunotherapy to determine any correlation between CD206 related uptake and treatment response.
