Progenics Announces the Initiation of Fuji's Phase 2 Trial for 1404 in Japan

TARRYTOWN, N.Y., April 7, 2015 (GLOBE NEWSWIRE) -- Progenics Pharmaceuticals, Inc. (Nasdaq:PGNX) today announced that its partner, FUJIFILM RI Pharma Co. Ltd. (Fuji), has dosed the first patient in its early Phase 2 trial of 1404 in Japan in newly-diagnosed prostate cancer patients with lymph node and/or bone metastases or at high risk for metastatic disease. 1404 is a targeted small molecule designed to visualize prostate cancer by targeting prostate specific membrane antigen (PSMA).

"1404 holds tremendous promise as the most advanced PSMA-targeted imaging agent in development today, and the initiation of this trial reflects Fuji's commitment to 1404 following the impressive data from our own Phase 2 study," stated Mark Baker, CEO of Progenics. "We have demonstrated that 1404 can provide diagnostic information for both primary and metastatic prostate cancer in a single scan, and we look forward to seeing the Japanese development program progress in parallel with our own plans in the United States."

The early Phase 2 trial in Japan is a multi-center, open-label study evaluating the uptake of 1404 within the prostate gland, pelvic lymph node and/or bone metastases as well as safety in men with high risk for metastatic prostate cancer, using both whole-body planar and SPECT/CT imaging modalities.

About 1404, an Imaging Compound Targeting Prostate Specific Membrane Antigen

1404 is a developmental stage radiopharmaceutical imaging agent designed to highlight the expression of distinct proteins by diseased cells. The image created provides the opportunity to visualize cancer, potentially allowing for improved detection and staging, more precise biopsies, and a targeted treatment plan including active surveillance as a disease management tool.

About Prostate Cancer

Prostate cancer is the second most common form of cancer affecting men in the United States: an estimated one in six will be diagnosed with prostate cancer in his lifetime. The American Cancer Society estimates that approximately 240,000 new cases of prostate cancer will be diagnosed and about 30,000 men will die of the disease this year, and that approximately two million men in the U.S. currently count themselves among prostate cancer survivors.
