By Hemanth 8:40pm ET- Lantheus Holdings, Inc. [LNTH] an established leader and fully integrated provider of innovative imaging diagnostics, targeted therapeutics and artificial intelligence solutions to find, fight and follow serious medical conditions,announced today that the U.S. Food and Drug Administration (FDA) has approved PYLARIFY, an F 18-labeled prostate-specific membrane antigen (PSMA) targeted positron emission tomography (PET) imaging agent toidentify suspected metastasis or recurrence of prostate cancer. PYLARIFY is the first and only commercially available approved PSMA PET imaging agent for prostate cancer. The product will be immediately available in parts of the mid-Atlantic and southern regions and availability is expected to rapidly expand over the next six months with broad availability across the U.S. anticipated by year end.“The FDA approval of PYLARIFY is a significant milestone for Lantheus and the prostate cancer community in the United States. We believe PYLARIFYrepresents a paradigm shift in the identification and management of patients with suspected metastasis or recurrent prostate cancer, providing more accurate and earlier detection of disease than conventional imaging so that doctors, along withpatients and their families, can make more informed treatment decisions,” said Mary Anne Heino, President and Chief Executive Officer of Lantheus. “I would like to thank the patients who participated in our clinical trials, the studyinvestigators and our employees, whose efforts made this achievement possible.”Identification of suspected metastatic disease in men consideringinitial definitive therapy is important to optimize treatment planning and to avoid futile interventions. Of men with localized prostate cancer who undergo initial curative intent/management, up to 50% may experience recurrence of their diseasewithin ten years of treatment.1 Recurrent disease is often detected by a rise in serum prostate-specific antigen (PSA) levels; however, conventional imaging, especially at low PSA levels, is notable to identify the location and extent of the disease in the majority of cases.2,3PYLARIFY wasdeveloped to target PSMA, a protein that is overexpressed on the surface of more than 90% of primary and metastatic prostate cancer cells.4 PYLARIFY binds to the target, enabling the reader of thePET scan to detect and locate the disease. Cyclotron production of F 18 offers high batch capacity and high image resolution, and F 18’s 110-minute half-life allows for wide geographic distribution.5,6“Conventional imaging has significant limitations in detecting prostate cancer, both in initial stagingand 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 wellbefore 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 Officerof 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 willhave a tremendous impact on patients’ lives.”The approval of PYLARIFY is based on data from two Company-sponsored pivotal studies (OSPREY andCONDOR) 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 PETimaging 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 doseof 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.
