NEW YORK, NY, USA I December 07, 2016 I Progenics Pharmaceuticals, Inc. (PGNX), an oncology company developing innovative medicines and other products for targeting and treating cancer, today announced that the first patient has been dosed in the Company’s Phase 2/3 clinical trial evaluating the diagnostic accuracy of its PSMA-targeted PET/CT imaging agent, 18F-DCFPyL (PyLTM).  PyL was discovered by a team led by Martin G. Pomper, M.D., Ph.D., William R. Brody Professor of Radiology at the Center for Translational Molecular Imaging at the Johns Hopkins University School of Medicine.

“There exists a significant need for approved molecular imaging modalities with both high sensitivity and specificity to detect high risk recurrent or metastatic prostate cancer early,” said Lawrence Saperstein, M.D., Assistant Professor, Department of Radiology and Biomedical Imaging, Chief, Nuclear Medicine Program Director, Nuclear Radiology Fellowship, Yale University School of Medicine, where the first patient was dosed. “We believe PyL, when used with a PET/CT scan, can provide treating physicians with more accurate disease detection, potentially leading to earlier diagnoses, more informed treatment decisions as well as the ability to monitor responses, and ultimately improved patient outcomes.” 

The Phase 2/3 study will enroll approximately 300 patients with high risk prostate cancer with recurrence or metastatic disease in the United States and Canada.  Primary endpoints of the study include the assessment of sensitivity and specificity of PyL PET/CT imaging to detect prostate cancer in the prostate gland and regional lymph nodes, as well as sensitivity in sites of metastasis or recurrence.  Secondary endpoints include safety and tolerability, detection rate, and pharmacokinetic parameters.

“This trial initiation represents a significant milestone for our PyL program, and is designed to help support registration of this novel imaging agent,” stated Mark Baker, Chief Executive Officer of Progenics. “The early clinical data for PyL have been quite impressive, underscoring its potential to transform disease management for prostate cancer, and we look forward to further demonstrating its diagnostic performance as we advance the trial.”

About PyL for PET Imaging of Prostate Cancer

PyL (also known as 18F-DCFPyL) is a clinical-stage, fluorinated PSMA-targeted PET imaging agent for prostate cancer that was discovered and developed at the Center for Translational Molecular Imaging at the Johns Hopkins University School of Medicine. A proof-of-concept study published in the April 2015 issue of the Journal of Molecular Imaging and Biology demonstrated that PET imaging with PyL showed high levels of PyL uptake in sites of putative metastatic disease and primary tumors, while rapidly clearing from other organs, suggesting the potential for high sensitivity and specificity in detecting prostate cancer while appearing to be safe and well tolerated.

About Progenics

Progenics Pharmaceuticals, Inc. is developing innovative medicines and other products for targeting and treating cancer, with a pipeline that includes several product candidates in later-stage clinical development.  These products in development include therapeutic agents designed to precisely target cancer (AZEDRA® and 1095), and PSMA-targeted imaging agents for prostate cancer (1404 and PyLTM) intended to enable clinicians and patients to accurately visualize and manage their disease.  In addition, in late 2015 Progenics acquired EXINI Diagnostics AB, a leader in the development of advanced artificial intelligence-based imaging analysis tools and solutions for medical decision support.  The acquisition of EXINI complements Progenics’ strategy to support its imaging and therapeutic agents with sophisticated analytical tools and other technologies to help physicians and patients visualize, understand, target and treat cancer.  Progenics’ first commercial product, RELISTOR® (methylnaltrexone bromide) for opioid-induced constipation, is partnered with and marketed by Valeant Pharmaceuticals International, Inc.
