Perspective Therapeutics’ VMT-α-NET Protocols Presented at the North American Neuroendocrine Tumor Society (NANETS) 2023 Symposium

SEATTLE, Oct. 10, 2023 (GLOBE NEWSWIRE) --  Perspective Therapeutics, Inc. (“Perspective” or “the Company”) (NYSE AMERICAN: CATX), today announced that two upcoming investigator-initiated trials (IIT) were presented at the North American Neuroendocrine Tumor Society (NANETS) 2023 Symposium in Montreal, Canada, which was held October 4-6, 2023.

Presentation One: Phase 1 Trial of Pb-212-VMT-alpha-NET in Select Metastatic or Inoperable Somatostatin Receptor Positive Tumors

Summary: This presentation detailed the planned protocol for the IIT Phase 1 trial of Pb-212-VMT-alpha-NET in patients with metastatic or inoperable somatostatin receptors positive (SSTR+) tumors to investigate if this new treatment can improve management of patients naïve to prior radioligand therapy. The study is an open-label, single arm, single-center, phase 1 trial evaluating the safety, tolerability, and pharmacokinetic properties of the alpha-emitting, systemic radioligand therapy agent Pb-212-VMT-alpha-NET in five different SSTR+ tumors: gastrointestinal neuroendocrine tumors (GI-NET), pheochromocytoma and paraganglioma (PPGL), small cell lung cancer (SCLC), renal cell carcinoma (RCC), and head and neck (H&N). Enrollment for this study is expected to commence in the first quarter of 2024.

Presenter: E. Mena, MD, National Cancer Institute, National Institutes of Health

Presentation Two: Phase 1/2 Trial of Pb-212-VMT-alpha-NET in GI Neuroendocrine Tumors and Pheochromocytoma/Paraganglioma Previously Treated with Radioligand Therapy

Summary: This presentation detailed the planned protocol for the IIT Phase 1/2 trial designed to determine if such a new treatment can improve management of patients who have progressed on beta-emitting radioligand therapy. This study is an open-label, single arm, single-center, Phase 1/2 study evaluating the safety, tolerability, and pharmacokinetic properties of the alpha-emitting, systemic radioligand therapy agent Pb-212-VMT-alpha-NET in somatostatin receptors (SSTR+) metastatic GI neuroendocrine tumors (GI-NETs) and pheochromocytoma/paraganglioma (PPGL) tumors. Enrollment for this study is expected to commence in the first quarter of 2024.

Presenter: J. Del Rivero, MD, National Cancer Institute, National Institutes of Health

“There are currently no approved targeted radiopharmaceuticals for NETs patients outside of the gastroenteropancreatic indication,” said Chief Executive Officer Thijs Spoor of Perspective Therapeutics. “We are excited to expand clinical studies to a wider range of cancer types in order to potentially expand therapeutic options for patients with these difficult to treat tumors.”

“We are delighted to have the NIH conduct these studies to investigate the safety and efficacy of [212Pb]VMT-alpha-NET in these expanded patient populations.” said Chief Medical Officer Markus Puhlmann, MD MBA, of Perspective Therapeutics. “These clinical studies are evaluating [212Pb]VMT-alpha-NET in a wide range of neuroendocrine tumors, where the unmet need is greatest.”

About neuroendocrine tumors
Neuroendocrine tumors form in cells that interact with the nervous system or in glands that produce hormones. They can originate in various parts of the body, most often in the gut or the lungs and can be benign or malignant. Neuroendocrine tumors are typically classified as pancreatic neuroendocrine tumors or non-pancreatic neuroendocrine tumors. According to cancer.net, it is estimated that more than 12,000 people in the United States are diagnosed with a NET each year. Importantly, neuroendocrine tumors are associated with a relatively long duration of survival compared to other tumors and as a result, there are approximately 175,000 people living with this diagnosis.

About VMT-α-NET
VMT-α-NET is a clinical stage targeted alpha particle therapy (TAT) radiopharmaceutical being developed for the treatment and diagnosis of somatostatin receptor subtype 2 (SSTR2) expressing neuroendocrine tumors, which are a rare and difficult-to-treat type of cancer. VMT-α-NET incorporates Perspective Therapeutics’ proprietary lead-specific chelator (PSC) to bind Pb-203 for SPECT imaging, and Pb-212 for alpha particle therapy.

About Perspective Therapeutics, Inc.
Perspective Therapeutics, Inc., is a diversified medical technology and 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 Lead-212 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 in the United States. The Company has also developed a proprietary Lead-212 generator to enable isotope supply for clinical trial and commercial operations.

In addition to its targeted alpha therapy programs, Perspective is the sole producer of Cesium-131 brachytherapy seeds which are commercially available in the United States for the treatment of prostate cancer and other solid tumors.
