Clinical trials

Persons diagnosed with thyroid cancer are often treated initially with a thyroidectomy, which is followed by ablation using Iodine-131, a therapy which has been shown to be effective and safe. Imaging of metastatic thyroid cancer has been performed with whole body I-131 and Iodine 123 (I-123) imaging for many decades and use I-123 for staging studies. Iodine 124 (I-124) is a radioisotope of iodine which emits a positron and is imaged using PET (positron emission tomography). This is a single arm prospective trial that evaluates the ability of Iodine-124 (I-124) to detect metastatic thyroid cancer compared to non-interventional, usual care I-123 and I-131 images.

This is a multi-arm prospective trial that evaluates the ability of a novel imaging radiolabeled agents to detect metastatic cancer in participants with solid tumors using a gallium 68 (68Ga-) or copper 64 (64Cu-) FAP-2286 tracer. FAP-2286 is a peptidomimetic molecule that that binds to Fibroblast Activation Protein (FAP). FAP is a transmembrane protein expressed on cancer-associated fibroblasts, and has been shown to be present on a number of solid tumors.

This is a single center study investigating the use of Fluoroethyltyrosine (FET) in the detection of brain tumors. FET accumulates in malignant cells within intracranial neoplasms and can be used to detect recurrent disease and characterize grade of glial neoplasms.

There is evidence that Actinium-225 Prostate-Specific Membrane Antigen (225Ac-PSMA) has a potentially higher level of efficacy than 177 Lutetium Prostate-Specific Membrane Antigen (177Lu-PSMA) as a radioligand therapy. This single center, pilot study will compare differences in the mechanisms of actinium-225 and lutetium-177 radioligand therapies (RLT) in participants with high or very high risk localized or locoregional prostate cancer planning on undergoing a prostatectomy.

This expanded access protocol is proposed to allow University of California San Francisco (UCSF) patients additional access to 18F-fluorocholine (FCH) Positron Emission Tomography (PET) imaging for localization of parathyroid adenomas.
