  • [18F]FMISO PET/CT After Transcatheter Arterial Embolization in Imaging Tumors in Patients With Liver Cancer

    This clinical trial studies how well 18F-fluoromisonidazole (\[18F\]FMISO) positron emission tomography (PET)/computed tomography (CT) works after transcatheter arterial embolization in imaging tumors in patients with liver cancer. Transcatheter arterial embolization blocks blood flow to tumor cells by inserting tiny foreign particles into an artery near the tumor. \[18F\]FMISO is a type of radioimaging agent that binds to large molecules in tumor cells that have a low level of oxygen, and the radiation given off by \[18F\]FMISO is picked up by a PET scan and this may help researchers learn whether changes occur in the tumors after treatment, which can help decide how well the treatment worked earlier than is currently possible

  • [18F]FTC-146 PET/MRI in Healthy Volunteers and in CRPS and Sciatica

    Chronic pain can result from injured or inflamed nerves, as occurs in people suffering from sciatica and CRPS. These nerve injuries or regions of nerve irritation are often the cause of pain in these conditions, but the current diagnostic tools are limited in pinpointing the area of origin. Several studies have implicated involvement of sigma-1 receptors in the generation and perpetuation of chronic pain conditions, others are investigating anti sigma-1 receptor drugs for the treatment of chronic pain. Using the sigma-1 receptor (S1R) detector and experimental radiotracer \[18F\]FTC-146 and positron emission tomography/magnetic resonance imaging (PET/MRI) scanner, the researchers may potentially identify the source of pain generation in patients suffering from complex regional pain syndrome (CRPS) and chronic sciatica. The ultimate goal is to assist in the optimization of pain treatment regimens using an \[18F\]FTC-146 PET/MRI scan.

    The study is not designed to induce any physiological/pharmacological effect.

  • 18F-FSPG PET/CT for Cancer Patients on Therapy

    The goal of this phase 2 study trial is to evaluate the utility of the radiolabel 18F-FSPG used before and after treatment to diagnose, predict, and evaluate response to therapy in patients with a wide variety of metastatic cancers.

  • 68Ga DOTA-TATE PET/CT in Somatostatin Receptor Positive Tumors

    The primary objective of the study is to evaluate 68Ga-DOTA TATE PET/CT for staging and monitoring response to chemotherapy in patients with carcinoid, neuroendocrine tumors, medullary thyroid cancer and other cancers expressing somatostatin receptors.

  • 68Ga-PSMA PET/CT or PET/MRI in Evaluating Patients With Recurrent Prostate Cancer

    This clinical trial studies gallium-68 (68Ga)-prostate specific membrane antigen (PSMA) (gallium Ga 68-labeled PSMA ligand Glu-urea-Lys\[Ahx\]) positron emission tomography (PET)/computed tomography (CT) or PET/magnetic resonance imaging (MRI) in identifying prostate cancer that may have returned after a period of improvement (biochemical recurrence). 68Ga-PSMA is a radiopharmaceutical that localizes to a specific prostate cancer receptor, which can then be imaged by the PET/CT or PET/MRI scanner.

  • 68Ga-RM2 PET/MRI in Biochemically Recurrent Prostate Cancer

    Prostate cancer (PC) remains the most-common non-cutaneous cancer diagnosed in American males, accounting for an estimated 174,560 estimated new cases and 31,620 estimated deaths in 2019. Up to 40% of the patients with prostate cancer develop biochemical recurrence within 10 years after initial treatment. Usually an increase of the prostate-specific antigen (PSA) llevel precedes a clinically detectable recurrence by months to years, and this is currently used as a screening test before and subsequent to treatment. However, disease advancement can be local, regional or systemic, and each has significantly different approaches to disease management. Unfortunately, PSA level does not differentiate between these disease stages.

    This phase 2-3 study explores the utility of radiolabel 68Ga-RM2, a 68-gallium (68Ga)-labeled gastrin-releasing peptide receptor (GRPr) antagonist, for positron emission tomography (PET) / magnetic resonance imaging (MRI) (collectively, PET/MRI) as a potential tool to help discriminate between disease stages in participants after treatment with surgery or radiation, who present persistently elevated PSA levels (ie, may have prostate cancer), but were negative for cancer with a diagnostic regular medical care computed tomography (CT) scan

    68Ga-RM2 (BAY86-7548) is also identified as a synthetic bombesin receptor antagonist. PET/MRI is the collective result of 2 scan processes (PET and MRI ) conducted during the same scan procedure (ie, a combined scan). After a regular medical care computed tomography (CT) scan, participants will be scanned with 68Ga-RM2 PET/MRI scan procedure. PET/MRI is used to assess the location, size, and metabolic activity of a suspected tumor.

    The 68Ga-RM2 radiolabel consisted of a ligand (the synthetic bombesin receptor antagonist) and the radioisotope 68Ga. The RM2 ligand targets gastrin-releasing peptide receptors (GRPr), commonly expressed by prostate cancer cells, and the radioisotope distinguishes those cells from the background. The criteria for scan "positivity" will be, when compared to background level of the liver (control), the 68Ga signal is stronger (positive - malignant) or weaker (negative - benign).

    This study will assess how well 68Ga-RM2 works in detecting prostate cancer in patients with

    68Ga-RM2 PET/MRI may be able to see smaller tumors than the standard of care contrast-enhanced CT or MRI scan.

  • Assessing the Suitability of an Imaging Probe for Use in Clinical Cell and Gene Therapy Trials in Cancer and Rheumatoid Arthritis

    The purpose of this study is to determine whether \[18F\]FHBG is suitable for use as an imaging probe in cancer or rheumatoid arthritis patients enrolled in cell or gene therapy trials. In this phase 1 study we will assess the safety and biodistribution of \[18F\]FHBG in patients.
