Lantheus Submits New Drug Application to FDA for PSMA-Targeted PET Imaging Agent

By News Release

Prostate Cancer | ICVLantheus Holdings, Inc., the parent company of Lantheus Medical Imaging, Inc. and Progenics Pharmaceuticals, Inc., a leader in the development, manufacture and commercialization of innovative diagnostic and therapeutic agents and products, have submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for PyL™ (18F-DCFPyL), a prostate specific membrane antigen (PSMA)-targeted positron emission tomography (PET) imaging agent for prostate cancer.

The NDA includes a request for Priority Review, which if granted, could shorten the FDA’s review of the NDA to six months from the time of acceptance, versus the standard review timeline of 10 months from acceptance. The Company expects to receive notification from the FDA confirming acceptance of the filing for substantive review in early December 2020.“The completion of our NDA submission marks a significant milestone for Lantheus and our PyL clinical development program,” said Mary Anne Heino, President and Chief Executive Officer of Lantheus.

"Prostate cancer is the second leading cause of cancer death in men. Fortunately, men can live for a long time with their disease if managed appropriately. There are approximately 3.2 million men in the United States annually living with this disease.1 We believe that PyL, if approved, will play an ongoing role in the diagnosis and management of prostate cancer.”

The NDA is supported by data from two pivotal studies (OSPREY and CONDOR), designed to establish the safety and diagnostic performance of PyL imaging across the disease continuum of prostate cancer. Results from OSPREY Cohort A demonstrated improvement in specificity and positive predictive value (PPV) of PyL PET imaging over conventional imaging in men with high risk prostate cancer. OSPREY Cohort B and CONDOR studied men with prostate cancer in various disease states, including biochemical recurrent prostate cancer, hormone sensitive prostate cancer, non-metastatic castrate resistant prostate cancer, and metastatic castrate resistant prostate cancer. OSPREY Cohort B demonstrated a sensitivity in detecting metastatic lesions, while CONDOR, in patients with biochemical recurrent prostate cancer and non-informative baseline findings, demonstrated a high correct localization rate and high detection rate, including patients with low PSA values. In the CONDOR study, 63.9% of patients had a change in intended disease management plans due to the PyL imaging results. We believe the results from these two studies, taken as a whole, demonstrate the ability of PyL to reliably detect and localize disease and could enable more appropriate patient management.

PyL has been administered in approximately 3,500 subjects globally, including the two Company sponsored studies, multiple investigator sponsored studies, as well as clinical use reported in the literature. Across all of these studies PyL has shown an attractive safety profile.

“We are extremely grateful to the prostate cancer patients and investigators who participated in PyL’s clinical development program,” said Istvan Molnar, MD, Chief Medical Officer of Lantheus. “We believe that the demonstrated strong diagnostic performance of PyL, will assist in treatment decisions and, ultimately, may improve patient outcomes. We look forward to working with the FDA during the regulatory process in pursuit of our goal of bringing PyL to patients.”
