GE Healthcare Initiates Clinical Trials for First-Ever PET Imaging Agent to Track Angiogenesis in Cancer; Company Seeks to Accelerate Diagnosis of Cancer and Track Effectiveness of Therapies.


CHALFONT ST GILES, England -- GE Healthcare, a division of the General Electric Company (NYSE NYSE

See: New York Stock Exchange
:GE), announced today that it has initiated a first-in-man clinical study designed to validate information provided by a molecular imaging agent in evaluating the extent and nature of cancer. Specifically, this proprietary positron emission tomography positron emission tomography: see PET scan.

The trial, overseen by David Brooks, MD, chief medical officer at GE IMANET is currently enrolling subjects at the Hammersmith Hospital in London. This imaging agent will be used to quantify response to therapy by imaging Stage IV metastatic Metastatic

"Angiogenesis is a characteristic process of many cancers, and we're excited to participate in this clinical trial, which may provide additional validation for the use of this novel molecular imaging agent in oncology applications," said Brooks. "Data from this program could establish a new measurement used to assess the effectiveness of treatment approaches in cancer."

 4 billion invested in the research and development of angiogenesis-based medicines, making this one of the most heavily funded areas of medical research in history. More than 60 anti-angiogenesis drugs are currently in clinical trials.

"Our vision is that one day clinicians will be able to detect the progression of cancers at an earlier stage, allowing rapid intervention, which can be monitored for effectiveness and adjusted quickly to compensate for any lack of response," says Don Black, head of research and development at GE Healthcare's Medical Diagnostics division. "We're using our unique capabilities in biology and engineering to develop imaging agents across all modalities that provide groundbreaking molecular diagnostic options. We're planning to utilize our synthesis platform for multi-site clinical trials and we're looking forward to collaborating with the pharmaceutical industry to enable more targeted therapies and better results for patients."

GE is planning to use its proprietary FASTlab synthesis platform for multi-site clinical trials and commercial production of this agent. This technology features a single-use cassette that contains pre-measured quantities of all chemicals needed for the synthesis of radiopharmaceuticals used by technicians in commercial and research radiopharmacies. FASTlab cassettes require virtually no assembly and easily snap into the synthesis module. Strictly controlled and consistent production of PET tracer candidates at each clinical site is essential and this is a cassette based synthesis system that is not limited to a single tracer molecule, and accelerates the set up and execution of these trials. GE Healthcare's goal is to make innovative tracers Tracers

Notes to the editor:

PET scans create physiological images of chemical changes, such as sugar metabolism, which occur in tissue. In PET, a patient is typically injected with a small amount of radiopharmaceutical radiopharmaceutical /ra·dio·phar·ma·ceu·ti·cal/ (-fahr?mah-soo´ti-k'l) a radioactive pharmaceutical, nuclide, or other chemical used for diagnostic or therapeutic purposes.  that releases positrons (i.e. the anti particle of the electron) which are absorbed in tissue, releasing two gamma rays Gamma rays

The radiopharmaceutical mostly used for clinical PET imaging currently is fluorine-18 2- fluoro-2-deoxyglucose ((18F)-FDG), whose uptake reflects glucose metabolism glucose metabolism,

 follows the same metabolic pathway as glucose. It is trapped in the cell where it accumulates at a rate proportional to glucose utilization. The accumulation of FDG is increased in tumor cells because of the higher metabolic rate. The higher FDG accumulation in tumors compared to normal tissue provides the basis for a high tumor-to-background ratio, which allows the detection and characterization of cancer. (18F)-FDG imaging is not completely specific to malignant tumors: inflammation, tuberculosis and certain non-malignant tumors also have increased uptake.

An approach to develop more functionally targeted molecular imaging PET agents like GE Healthcare's PET angiogenesis agent that binds to the process of angiogenesis in the body could help physicians identify the location and growth patterns of tumors. Imaging the angiogenic process at the molecular level could also enable researchers and clinicians to monitor the effectiveness of anti-angiogenic drugs and patient response to cancer therapy.

GE Healthcare's Medical Diagnostics R&D team creates novel diagnostic imaging agents that are used during medical scanning procedures to highlight organs and tissues inside the human body, for the early detection, diagnosis and management of disease. Research efforts are currently focused on the unmet medical needs in neurology, oncology, and cardiology, with an emphasis on functional and molecular imaging agents that help doctors evaluate the physiology of disease and make treatment decisions earlier with confidence.
