- Mayo Clinic’s PSMA Alpha-PET DoubLET platform allows for imaging and targeted therapy with alpha and/or beta-particle radiopharmaceutical therapy (RPT) using a novel 64/67Cu and 203/212Pb double chelator design.
- PSMA Alpha-PET DoubLET licensing provides Perspective with a strongly differentiated prostate cancer program
SEATTLE, Jan. 05, 2024 (GLOBE NEWSWIRE) — Perspective Therapeutics, Inc. (“Perspective” or “the Company”) (NYSE AMERICAN: CATX), announced today that it has entered into a patent license agreement with Mayo Clinic for the rights to the PSMA Alpha-PET DoubLET platform technology for the treatment of PSMA-expressing cancers, with an initial focus on prostate.
The PSMA Alpha-PET DoubLET platform technology represents a potential leap forward in the field of prostate cancer diagnostics and treatment. This leading radiopharmaceutical platform provides detailed PET imaging-based diagnosis and dosimetry using long-lived copper-64 (64Cu) for imaging and alpha-particle targeted RPT using lead-212 (212Pb). It can also be used for beta-particle targeted RPT using copper isotopes. Preclinical studies demonstrated a high degree of radiation delivered to tumors while minimizing exposure to critical organs and tissues.
“This innovative approach developed by Mayo Clinic allows for more precise and personalized treatment plans,” said Thijs Spoor, Chief Executive Officer at Perspective Therapeutics. “This new license furthers our goal to bring new best-in-class products to the clinic that improve efficacy and minimize side effects.”
“It is not enough to develop a more powerful therapy. We focused on diagnostic accuracy, patient tolerance and convenience. PSMA Alpha-PET aims to improve the overall experience of individuals undergoing prostate cancer radiopharmaceutical therapy,” commented co-inventor Geoff Johnson, MD, PhD, Chair of Nuclear Medicine, Associate Director of the Mayo Clinic Comprehensive Cancer Center and Director of the Radiopharmaceutical Trial Disease Team. “The platform’s innovative design provides rapid and high-quality quantitative PET imaging to guide alpha and/or beta-particle RPT, with a reasonable workflow that patients and clinics can follow.”
Co-inventor Mukesh Pandey, PhD, FRSC, Professor of Radiology and Director of Mayo Clinic Molecular Imaging Research Program said, “The team at Mayo Clinic conducted rigorous scientific experiments to validate the specific targeting of PSMA Alpha-PET to prostate tumors compared to other normal tissues. We are pleased to report that this compound performed very favorably in the preclinical setting where it had significantly less salivary gland uptake and improved kidney clearance than comparators. PSMA Alpha-PET was also effective in treating mice with prostate cancer tumor implants and was well tolerated.”
Dr. Markus Puhlmann, Chief Medical Officer of Perspective Therapeutics added, “PSMA Alpha-PET is a potentially groundbreaking solution that addresses some of the limitations of existing products in prostate cancer imaging and treatment. We are committed to advancing medical technology that we believe will make a meaningful difference in the lives of those affected by prostate cancer.”
Mayo Clinic has a financial interest in the technology referenced in this press release. Mayo Clinic will use any revenue it receives to support its not-for-profit mission in patient care, education and research.
About Prostate Cancer
Prostate cancer is the second-most prevalent form of cancer affecting men worldwide, emphasizing the critical need for advanced technologies to improve early detection and treatment outcomes. For 2023, the Cancer Institute estimated 88,300 new cases of prostate cancer in the US and around 34,700 deaths from the disease.
About Perspective Therapeutics, Inc.
Perspective Therapeutics, Inc., is a radiopharmaceutical company that is pioneering advanced treatment applications for cancers throughout the body. The Company has a proprietary technology that utilizes the alpha emitting isotope 212Pb to deliver powerful radiation specifically to cancer cells via specialized targeting peptides. The Company is also developing complementary imaging diagnostics that incorporate the same targeting peptides which provide the opportunity to personalize treatment and optimize patient outcomes. This “theranostic” approach enables the ability to see the specific tumor and then treat it to potentially improve efficacy and minimize toxicity associated with many other types of cancer treatments.
The Company’s melanoma (VMT01) and neuroendocrine tumor (VMT-α-NET) programs have entered Phase 1/2a imaging and therapy trials for the treatment of metastatic melanoma and neuroendocrine tumors at several leading academic institutions. The Company has also developed a proprietary 212Pb generator to secure key isotopes for clinical trial and commercial operations.
