On December 3, 2018 Progenics Pharmaceuticals, Inc. (NASDAQ:PGNX), an oncology company developing innovative medicines and imaging analysis technology for targeting and treating cancer, reported that the first patient has been dosed in the Company’s Phase 3 CONDOR study evaluating the diagnostic performance and clinical impact of PyL (18F-DCFPyL) in men with biochemical recurrence of prostate cancer (Press release, Progenics Pharmaceuticals, DEC 3, 2018, View Source [SID1234531895]). PyL is the Company’s PSMA-targeted small molecule PET/CT imaging agent designed to visualize prostate cancer.

Dr. Lawrence Saperstein, Assistant Professor of Radiology and Biomedical Imaging and Chief of Nuclear Medicine at Yale Smilow Cancer Hospital, and a principle investigator of the trial said, "PyL has demonstrated excellent positive and negative predictive values in detecting the presence or absence of prostate cancer. This valuable information has the potential to provide earlier diagnoses, more informed treatment decisions, the ability to monitor responses, and ultimately improve patient outcomes."

The Phase 3 CONDOR trial is a multi-center, open label study and will enroll approximately 200 patients with biochemical recurrence of prostate cancer in 14 sites in the United States and Canada. The primary endpoint is based on positive predictive value and will assess the correct localization rate (CLR), defined as a percentage of subjects with a one-to-one correspondence between localization of at least one lesion identified by PyL and the composite truth standard. Secondary measures include the percentage of subjects with a change in intended prostate cancer treatment plans due to PyL PET/CT imaging.

"The initiation of this landmark trial marks an important milestone in the development of PSMA-targeted imaging agents which have the potential to transform the treatment landscape for recurrent prostate cancer," stated Mark Baker, CEO of Progenics. "With PyL, physicians may be able to detect very small lesions that are currently missed with conventional imaging methods, which in turn could change the treatment path. We look forward to reporting data from this trial in early 2020."

In prior studies, PyL has shown strong positive predictive value to detect prostate cancer, with high sensitivity (93-99%) in reliably detecting metastatic prostate cancer lesions and high specificity (96-99%) in confirming the absence of pelvic lymph node disease.

About PyL for PET Imaging of Prostate Cancer

PyL (also known as [18F]DCFPyL) is a fluorinated PSMA-targeted Positron Emission Topography ("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 seven men will be diagnosed with prostate cancer in his lifetime. The American Cancer Society estimates that each year approximately 164,690 new cases of prostate cancer will be diagnosed and about 29,430 men will die of the disease. Approximately 2.9 million men in the U.S. currently count themselves among prostate cancer survivors
