New PET agent may ‘revolutionize’ diagnostic workup for numerous diseases

Molecular Targeting Technologies, a radiotherapeutics biotech company focused on cancer, announced a new PET imaging agent to help clinicians monitor cancers' response to therapy.

MTTI won a patent from the U.S. Patent and Trademark Office for its F-18 fluroglucaric (F-18-FGA) acid necrosis agent, the firm announced Tuesday. The West Chester, Pennsylvania-based company can convert commercially available 18F-deoxyglucose (18F-FDG) to 18-F-FGA in as little as five minutes, according to the patent.

In addition to monitoring tumor response, the tracer can image the death of cancerous cells within tumors, known as necrosis, and track organ fibrosis in kidney disease and liver fibrosis. For decades researchers have been searching for an agent that can pull this off without accumulating in the body, MTTI President and CEO Chris Pak noted.

“An 18F-FGA imaging agent for necrosis can revolutionize a diagnostic workup of many human diseases where tissue necrosis occurs as part of the pathology,” inventors of the radiopharmaceutical Vibhudutta Awasthi, PhD, and Hailey Houson, PhD, both with the University of Oklahoma, said in a statement.

The tracer also allows the use of high-resolution and sensitivity PET to spot myocardial infarction and brain stroke, privately held MTTI noted.

“We’re excited for this discovery and look forward to advancing this molecule to clinic,” Pak added.

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.

The newly cleared offering, AutoChamber, was designed with opportunistic screening in mind. It can evaluate many different kinds of CT images, including those originally gathered to screen patients for lung cancer.
