NORTH BILLERICA, Mass., March 29, 2022 (GLOBE NEWSWIRE) -- Lantheus Holdings, Inc. (“the Company”) (NASDAQ: LNTH), an established leader and fully integrated provider committed to innovative imaging diagnostics, targeted therapeutics and artificial intelligence solutions to Find, Fight and Follow serious medical conditions, today announced a strategic collaboration with Novartis to include PYLARIFY® (piflufolastat F18) in prostate cancer clinical trials with Pluvicto™ (lutetium Lu 177 vipivotide tetraxetan).
“The FDA-approval of Novartis’ Pluvicto brings hope to patients and is an exciting advancement in the field of radiopharmaceutical oncology,” said Mary Anne Heino, President and CEO of Lantheus. “We look forward to collaborating to further explore how PSMA PET imaging agents, like PYLARIFY, may aid in increasing accessibility to PSMA-targeted therapeutics. As always, our goal is to Find, Fight and Follow serious medical conditions and improve patient outcomes.”
PYLARIFY, approved by the FDA in May 2021, is the first commercially and widely available prostate-specific membrane antigen (PSMA) PET imaging agent. The collaboration with Novartis directly aligns with Lantheus’ strategy to advance cancer precision medicine by enabling partners to use PYLARIFY in prostate cancer therapeutic trials. As part of the agreement with Novartis, Lantheus will provide PYLARIFY for the selection of patients with prostate cancer and Novartis will provide all PYLARIFY related clinical imaging data to Lantheus.
The Company believes the approval of a PSMA-targeted therapeutic for the treatment of adult patients with PSMA-positive metastatic castration-resistant prostate cancer (mCRPC) who have already been treated with other anticancer treatments (androgen receptor pathway inhibition and taxane-based chemotherapy) creates a new addressable market for the use of PSMA PET imaging in patient selection for PSMA-targeted therapy. As a result, the Company estimates the U.S. Total Addressable Market (TAM) for all PSMA PET imaging increases by approximately 30,000 de novo scans per year for this mCRPC patient population. The Company now estimates the TAM to be 250,000 scans, or approximately $1.1 billion, up from its previous estimate of 220,000 scans.
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 2022, almost 268,500 new cases of prostate cancer will be diagnosed, and about 34,500 men will die of the disease. Approximately 3.1 million men in the United States currently count themselves as prostate cancer survivors.1
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 radioisotope 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.2-7
PYLARIFY® (piflufolastat F 18) Injection
Indication
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
Contraindications
None.
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.
Hypersensitivity Reactions
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.
Radiation Risks
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.
Adverse Reactions
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.
Drug interactions
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.
