Lantheus Holdings to Showcase the Potential of PyL™ Imaging Agent at the Virtual Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2020 Annual Meeting

On July 1, 2020 Lantheus Holdings, Inc. (the "Company") (NASDAQ: LNTH), the parent company of Lantheus Medical Imaging, Inc. and Progenics Pharmaceuticals, Inc., and a global leader in the development, manufacture and commercialization of innovative diagnostic and therapeutic agents and products, reported that 17 abstracts highlighting PyL (18F-DCFPyL) have been selected for presentation at the virtual Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2020 Annual Meeting taking place July 11-14, 2020 (Press release, Lantheus Medical Imaging, JUL 1, 2020, View Source [SID1234561627]). PyL is the PSMA-targeted small molecule positron emission tomography (PET) imaging investigational agent designed to visualize prostate cancer, which the Company recently purchased as part of the oncology business of Progenics.

The abstracts to be presented at the meeting will feature data on PyL from two presentations based on Company-sponsored studies, including the positive results from the Phase 3 CONDOR trial evaluating the diagnostic performance and clinical impact of PyL in patients with biochemical recurrence of prostate cancer. A third abstract focuses on the digital solution the Company is developing in parallel with PyL to potentially support prostate cancer staging using an automated miPSMA Index of the PET/CT PyL-PSMA images.

"Physicians and patients continue to experience an unmet need for diagnostic imaging that could assist in staging high risk prostate cancer and reliably detect recurrent or metastatic disease. The unmet need is particularly important among patients with low PSA values," said Istvan Molnar, M.D., the Company’s Chief Medical Officer. "We believe that the demonstrated strong diagnostic performance of our PSMA-targeted PET imaging investigational agent, PyL, could provide clinicians with actionable information. In addition, the use of the widely available isotope fluorine-18 may result in broad patient accessibility. Data to be presented at SNMMI this year further highlights PyL’s clinical potential, including the positive Phase 3 results of the CONDOR study, which achieved its primary endpoint with a correct localization rate of 84.8% to 87.0% among the three blinded independent readers. We remain on track to submit a New Drug Application ("NDA") with the U.S. Food and Drug Administration ("FDA") for PyL in the third quarter of 2020."

SNMMI presentations will be made available on July 11, 2020 and can be found in the virtual Science Pavilion.

Details for the SNMMI 2020 presentations based on Company-sponsored studies and Company-led digital solution development are as follows:

About PyL for PET Imaging of Prostate Cancer

PyL (also known as 18F-DCFPyL) is a fluorinated PSMA-targeted positron emission tomography (PET) imaging agent that enables visualization of both bone and soft tissue metastases to determine the presence or absence of recurrent and/or metastatic prostate cancer.

About Prostate Cancer

Prostate cancer is the second most common form of cancer affecting men in the United States: an estimated one in nine men will be diagnosed with prostate cancer in his lifetime. The American Cancer Society estimates that each year approximately 174,650 new cases of prostate cancer will be diagnosed and about 31,620 men will die of the disease. Approximately 2.9 million men in the U.S. currently count themselves among prostate cancer survivors.
