“Conventional imaging has significant limitations in detecting prostate cancer, both in initial staging and when the cancer has recurred or spread after initial primary treatment. Specifically, standard imaging poorly detects the early spread to distant organs, such as the lymph nodes, bones, and other organs,” said Michael J. Morris, M.D., Prostate Cancer Section Head, Genitourinary Medical Oncology, Memorial Sloan Kettering Cancer Center and the Lead Study Investigator in the CONDOR trial and Study Investigator in the OSPREY trial. “PYLARIFY can detect the spread of disease well before standard imaging and can be a transformative diagnostic tool that helps clinicians develop treatment plans based on a much more accurate understanding of a patient’s distribution of disease.”

“We believe today’s approval is a game-changer for men facing prostate cancer," said Jamie Bearse, Chief Executive Officer of ZERO - The End of Prostate Cancer, a Patient Advocacy Group. "Having a diagnostic tool that allows doctors to see suspected metastatic or recurrent prostate cancer earlier, anywhere in the body, is a significant step forward and will have a tremendous impact on patients' lives.”


The approval of PYLARIFY is based on data from two Company-sponsored pivotal studies (OSPREY and CONDOR) designed to establish the safety and diagnostic performance of PYLARIFY across the prostate cancer disease continuum. Results from OSPREY (Cohort A) demonstrated improvement in specificity and positive predictive value (PPV) of PYLARIFY PET imaging over conventional imaging in men at risk for metastatic prostate cancer prior to initial therapy. CONDOR studied men with biochemical recurrent prostate cancer. In patients with biochemical recurrent prostate cancer and non-informative baseline imaging, PYLARIFY demonstrated high correct localization and detection rates, including in patients with low PSA values (median PSA 0.8 ng/mL).

In the clinical trials, PYLARIFY was well tolerated. In OSPREY and CONDOR, 593 patients with various states of prostate cancer were exposed to a single dose of PYLARIFY. Adverse reactions (headache, dysgeusia and fatigue) were reported in ≤ 2% of patients within the studies. In addition, a delayed hypersensitivity reaction was reported in one patient (0.2%) with a history of allergic reaction.

About PYLARIFY®

PYLARIFY® (piflufolastat F 18) injection (also known as 18F-DCFPyL or PyL) is a fluorinated small molecule PSMA-targeted PET imaging agent that enables visualization of lymph nodes, bone and soft tissue metastases to determine the presence or absence of recurrent and/or metastatic prostate cancer. For men with prostate cancer, PYLARIFY PET combines the accuracy of PET imaging2, the precision of PSMA targeting and the clarity of an F 18 radioisotope5 for superior diagnostic performance. The recommended PYLARIFY dose is 333 MBq (9 mCi) with an acceptable range of 296 MBq to 370 MBq (8 mCi to 10 mCi), administered as a bolus intravenous injection.1,5,7,8,9
