Progenics Pharmaceuticals Announces Phase 3 CONDOR Trial of PyL™ in Prostate Cancer Achieved Primary Endpoint

- Met Primary Endpoint With a Correct Localization Rate of 84.8–87.0%, Highlighting Strong Diagnostic Performance
- Company Expects to Submit an NDA to the FDA in the Second Half of 2020
- Conference Call at 8:00 AM Eastern Time

NEW YORK, Dec. 23, 2019 (GLOBE NEWSWIRE) -- Progenics Pharmaceuticals, Inc. (Nasdaq:PGNX), an oncology company developing innovative targeted medicines and artificial intelligence to find, fight and follow cancer, today announced positive top line results from the Phase 3 CONDOR trial evaluating the diagnostic performance and clinical impact of PyL™ (18F-DCFPyL) in men with biochemical recurrence of prostate cancer. PyL is the Company’s PSMA-targeted small molecule positron emission tomography (PET) imaging agent designed to visualize prostate cancer.

“There is a need for improved diagnostics for prostate cancer to replace conventional imaging tests that have limited performance characteristics, especially in men with biochemical recurrence of their disease,” said Barry Siegel, MD, Professor of Radiology at Washington University School of Medicine in St. Louis. “The high positive predictive value demonstrated in this study reflects the clinical utility of PSMA-targeted PET imaging agents providing actionable information to physicians to guide treatment plans and improve disease management of one of the most prevalent cancers in the U.S.”

The Phase 3 CONDOR trial is a prospective, multi-center, open label pivotal trial in which 208 patients with biochemical recurrence of prostate cancer and uninformative baseline imaging based on conventional modalities (i.e. Axumin, Choline PET, CT/MR and/or bone scan) were dosed and imaged with PyL at 14 sites in the United States and Canada. The CONDOR trial achieved its primary endpoint, with a correct localization rate (CLR) of 84.8% to 87.0% among the three blinded independent readers (the lower bound of the 95% confidence intervals ranging from 77.8% to 80.4%). CLR is based on positive predictive value, defined as the percentage of patients with a one-to-one correspondence between localization of at least one lesion identified on 18F-DCFPyL PET/CT and a composite truth standard comprised of histopathology, conventional imaging and/or changes in PSA levels following radiation therapy.

Safety results showed PyL was well tolerated, consistent with the Phase 2 OSPREY trial results. There was one serious adverse event of hypersensitivity reported in one patient as related to the study drug. The most frequent adverse event reported was headache, which was reported in four patients (1.9% of the trial population).

“The positive results of our Phase 3 CONDOR trial reinforce our belief in the potential of PyL to enable better physician treatment decisions and, ultimately, improve patient outcomes. The rapid trial enrollment and physician support further underscore the excitement and positive reception of PyL as a new addition in the fight against prostate cancer and, together with the commercial performance of diagnostic agents in use today, reinforce our belief in the significant market opportunity for PyL,” said David Mims, Interim CEO. “Based on these positive results, we plan to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for PyL in the second half of 2020.”

Additional results from the CONDOR trial are expected to be presented at an upcoming medical meeting.

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.
