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.

Study Evaluating 89Zr Panitumumab for Assessment of Indeterminate Metastatic Lesions on 18F-FDG-PET/CT in Head and Neck Squamous Cell Carcinoma

The goal of this phase I clinical trial is to evaluate the usefulness of an imaging test (zirconium Zr 89 panitumumab [89Zr panitumumab]) with positron emission tomography (PET)/computed tomography (CT) for diagnosing the spread of disease from where it first started (primary site) to other places in the body (metastasis) in patients with head and neck squamous cell carcinoma. Traditional PET/CT has a low positive predictive value for diagnosing metastatic disease in head and neck cancer. 89Zr panitumumab is an investigational imaging agent that contains radiolabeled anti-EGFR antibody which is overexpressed in head and neck cancer. The main question this study aims to answer is the sensitivity and specificity of 89Zr panitumumab for the detection of indeterminate metastatic lesions in head and neck cancer. Participants will receive 89Zr panitumumab infusion and undergo 89Zr panitumumab PET/CT 1 to 5 days after infusion. Participants will otherwise receive standard of care evaluation and treatment for their indeterminate lesions. Researchers will compare the 89Zr panitumumab to standard of care imaging modalities (magnetic resonance imaging (MRI), CT, and/or PET/CT).

Evaluating 111In Panitumumab for Nodal Staging in Head and Neck Cancer

This phase I trial tests the safety and effectiveness of indium In 111 panitumumab (111In-panitumumab) for identifying the first lymph nodes to which cancer has spread from the primary tumor (sentinel lymph nodes) in patients with head and neck squamous cell carcinoma (HNSCC) undergoing surgery. The most important factor for survival for many cancer types is the presence of cancer that has spread to the lymph nodes (metastasis). Lymph node metastases in patients with head and neck cancer reduce the 5-year survival by half. Sometimes, the disease is too small to be found on clinical and imaging exams before surgery. 111In-panitumumab is in a class of medications called radioimmunoconjugates. It is composed of a radioactive substance (indium In 111) linked to a monoclonal antibody (panitumumab). Panitumumab binds to EGFR receptors, a receptor that is over-expressed on the surface of many tumor cells and plays a role in tumor cell growth. Once 111In-panitumumab binds to tumor cells, it is able to be seen using an imaging technique called single photon emission computed tomography/computed tomography (SPECT/CT). SPECT/CT can be used to make detailed pictures of the inside of the body and to visualize areas where the radioactive drug has been taken up by the cells. Using 111In-panitumumab with SPECT/CT imaging may improve identification of sentinel lymph nodes in patients with head and neck squamous cell cancer undergoing surgery.

Application of FDG Combined With FAPI PET Dual Imaging in the Diagnosis and Staging of Oropharyngeal and Laryngeal Cancer

According to statistics, in 2020, new head and neck malignancies in the world accounted for 4.9% (931931 cases) of malignant tumors in the whole body, and the new death cases were 467125, accounting for 4.7% of malignant tumors in the whole body. The high incidence rate and mortality brought great burden to the medical system. In addition, due to various types of head and neck cancer, hidden location, impact on function and quality of life, and low overall survival rate, this type of disease has seriously threatened human health and social development. The incidence of oropharyngeal cancer and laryngeal cancer is more subtle. Traditional examination methods include CT(computer tomography), MR(magnetic resonance), and laryngoscopy, but they cannot make accurate judgments on the systemic TNM(primary tumor, regional nodes, metastasis) staging of oropharyngeal cancer and laryngeal cancer. 18F-FDG(18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose) PET/CT examination can better diagnose and stage compared to traditional examination methods. However, due to the interference of more inflammatory lesions or physiological uptake in the pharynx, the false positive rate of 18F-FDG PET/CT examination is significantly increased, 18F-FAPI(18F-fibroblast activation protein inhibitors) is a novel broad-spectrum tumor imaging agent that can be specifically uptake by fibroblasts in the tumor microenvironment, and has lower physiological uptake and acute inflammatory lesion uptake in the larynx. 18F-FAPI PET/CT examination can more accurately stage tumors throughout the body than 18F-FDG PET/CT examination. Combined with PET/MR local scanning, it will further improve the accuracy of T and N staging of local tumors. Therefore, It is of great significance for clinical diagnosis and treatment to effectively and reliably determine the systemic TNM staging of oropharyngeal and laryngeal cancer through non-invasive methods.

Phase I Trial of [212Pb]VMT-Alpha-NET in Metastatic or Inoperable Somatostatin-Receptor Positive Gastrointestinal Neuroendocrine Tumors, Pheochromocytoma/Paragangliomas, Small Cell Lung, Renal Cell, and Head and Neck Cancers

Some cancers have high levels of proteins called somatostatin receptors (SSTRs) on the surface of the tumors. These tumors can be in the lung, head and neck, digestive tract, kidneys, and in or near the adrenal glands. Researchers want to know if drug treatments that target SSTRs can help shrink these types of tumors.

Imaging CCR2 Receptors With 64Cu-DOTA-ECL1i in Head and Neck Cancer

CCR2 is a significant prognostic biomarker in head and neck cancer. Currently there is no clinical biomarker to study CCR2, its prognostic significance or to select patients for CCR2-targeted therapy and to monitor response to such therapy. The investigators have developed a CCR2 specific PET radiotracer based on the peptide, ECL1i (d(LGTFLKC)) and radiolabeled with 64Cu (64Cu-DOTA-ECL1i). The investigators have found that 64Cu-DOTA-ELC1i specific binding has been demonstrated in human head and neck cancer tissue.

Radiogenomics in Aerodigestive Tract Cancers

Aerodigestive tract cancers are common malignancies. These cancers were ranked to be top-ten cancer-related deaths in Taiwan. Although many new target therapies and immunotherapies have emerged, many of the treatment eventually fail. For example, a 30-40% failure rate has been reported for target therapy, and, even higher for immune checkpoint inhibitors. A reliable model to more accurately predict treatment response and survival is warranted. The radiomic features extracted from F-18 fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) can be used to figure tumor biology such as metabolome and heterogeneity. It can therefore be used to predict treatment response and individual survival. On the other hand, genomic data derived from next-generation sequencing (NGS) can interrogate the genetic alteration of cancer cells. It can be used to feature genetic identification of the tumor and can also be used to identify target genes. However, both modalities have their weakness; a combination of the two may devise a more powerful predictive model for more precise clinical decision. The investigators plan to recruit patients aged at least 20-year with the diagnosis of aerodigestive tract cancers for radiogenomic study. Our previous studies have found that radiomic features derived from 18F-FDG PET can predict treatment response and survival in patients with esophageal cancer treated with tri-modality method. The investigators also discovered that radiomics could predict survival in patients with EGFR-mutated lung adenocarcinoma treated with target therapy. In addition, our study results showed that the level of PD-L1 expression is associated with radiomics as well. The investigators plan to add genomic data into radiomics and interrogate cancers from different aspects. The investigators seek to devise a more precise model to predict the treatment response and survival in patients with aerodigestive tract cancers.
