aPROMISE was developed to quantify and standardize assessment of PSMA PET/CT images and will support PYLARIFY® (piflufolastat F 18) adoption in the U.S.
Lantheus Holdings, Inc. (NASDAQ: LNTH) (Lantheus) announced today that its subsidiary, EXINI Diagnostics AB, was granted 510(k) clearance by the U.S. Food and Drug Administration (FDA) for its digital application, aPROMISE™ (automated PROstate Cancer Molecular Imaging Standardized Evaluation). Clinicians will have the option to utilize aPROMISE with PYLARIFY® (piflufolastat F 18) to increase the efficiency and reproducibility of their PSMA PET/CT assessments. PYLARIFY was recently approved by the FDA and is the first and only commercially available PSMA-targeted PET imaging agent for prostate cancer.
aPROMISE is an artificial intelligence-based, medical device software that uses a deep learning algorithm trained and validated across over 3,000 PSMA images to date, to allow healthcare professionals and researchers to perform quantitative assessment of PSMA PET/CT images in prostate cancer. The PROMISE criteria were developed by leading experts in prostate cancer imaging to standardize quantitative evaluation of prostate cancer lesions by location using prostate-specific membrane antigen (PSMA) PET/CT.1 aPROMISE facilitates rapid and robust quantification of prostate cancer lesions in anatomical context, enabling clinicians to make routine use in the clinic of a comprehensive, automated approach to patient evaluation. aPROMISE includes a solution for automated body segmentation and marking, quantifying and reporting suspicious lesions in their anatomical context. aPROMISE provides enhanced consistency in quantitative analysis and standardized reports and has demonstrated increased efficiency and reproducibility of clinicians’ PSMA PET/CT image assessments.2,3
“Lantheus is pleased with the FDA clearance of aPROMISE, our AI-enabled digital application that expands our PSMA platform,” said Etienne Montagut, Chief Business Officer for Lantheus. “We are excited to provide such an innovative tool for PSMA quantification and reporting that can empower clinicians to make more informed treatment decisions for their prostate cancer patients.”
aPROMISE Indications for Use
aPROMISE is intended to be used by healthcare professionals and researchers for acceptance, transfer, storage, image display, manipulation, quantification and reporting of digital medical images. The system is intended to be used with images acquired using nuclear medicine (NM) imaging using PSMA PET/CT. The device provides general Picture Archiving and Communications System (PACS) tools as well as a clinical application for oncology including marking of regions of interest and quantitative analysis.
About Prostate Cancer
Prostate cancer is the second most common form of cancer affecting men in the United States -- an estimated one in eight men will be diagnosed with prostate cancer in their lifetimes. The American Cancer Society estimates that in 2021, almost 250,000 new cases of prostate cancer will be diagnosed, and more than 30,000 men will die of the disease. Approximately 3.1 million men in the United States currently count themselves as prostate cancer survivors.4
About PYLARIFY® (piflufolastat F 18) Injection
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 imaging, 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.6-10
PYLARIFY® (piflufolastat F 18) Injection
PYLARIFY® (piflufolastat F 18) Injection is a radioactive diagnostic agent indicated for positron emission tomography (PET) of prostate-specific membrane antigen (PSMA) positive lesions in men with prostate cancer:
- with suspected metastasis who are candidates for initial definitive therapy.
- with suspected recurrence based on elevated serum prostate-specific antigen (PSA) level.
Important Safety Information
Warnings and Precautions
Risk of Image Misinterpretation
Imaging interpretation errors can occur with PYLARIFY imaging. A negative image does not rule out the presence of prostate cancer and a positive image does not confirm the presence of prostate cancer. The performance of PYLARIFY for imaging of patients with biochemical evidence of recurrence of prostate cancer seems to be affected by serum PSA levels. The performance of PYLARIFY for imaging of metastatic pelvic lymph nodes prior to initial definitive therapy seems to be affected by risk factors such as Gleason score and tumor stage. PYLARIFY uptake is not specific for prostate cancer and may occur with other types of cancer as well as non-malignant processes and in normal tissues. Clinical correlation, which may include histopathological evaluation of the suspected prostate cancer site, is recommended.
Monitor patients for hypersensitivity reactions, particularly patients with a history of allergy to other drugs and foods. Reactions may be delayed. Always have trained staff and resuscitation equipment available.
Diagnostic radiopharmaceuticals, including PYLARIFY, expose patients to radiation. Radiation exposure is associated with a dose-dependent increased risk of cancer. Ensure safe handling and preparation procedures to protect patients and health care workers from unintentional radiation exposure. Advise patients to hydrate before and after administration and to void frequently after administration.
The most frequently reported adverse reactions were headaches, dysgeusia and fatigue, occurring at rate of ≤2% during clinical studies with PYLARIFY. In addition, a delayed hypersensitivity reaction was reported in one patient (0.2%) with a history of allergic reactions.
Androgen deprivation therapy (ADT) and other therapies targeting the androgen pathway, such as androgen receptor antagonists, may result in changes in uptake of PYLARIFY in prostate cancer. The effect of these therapies on performance of PYLARIFY PET has not been established.
To report suspected adverse reactions for PYLARIFY, call 1-800-362-2668 or contact FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
