SEATTLE, Oct. 10, 2024 (GLOBE NEWSWIRE) -- Perspective Therapeutics, Inc. (“Perspective” or the “Company”) (NYSE AMERICAN: CATX), a radiopharmaceutical company that is pioneering advanced treatment applications for cancers throughout the body, today announced that initial results from its Phase 1/2a study of [²¹²Pb]VMT01 have been selected for a poster presentation at the 21^st International Congress of the Society for Melanoma Research (“SMR”), being held on October 10-13, 2024 in New Orleans, Louisiana.

The title of the poster presentation for the Phase 1/2a study of [²¹²Pb]VMT01 is “First in Human Peptide Receptor Radionuclide Therapy (PRRT) for Metastatic Melanoma (MM).”

“We are looking forward to our first scientific presentation of clinical data from a company sponsored study,” said Thijs Spoor, Perspective Therapeutics' CEO. “Meanwhile, we continue to explore the optimal dose of [²¹²Pb]VMT01 in metastatic melanoma, both as a single agent and in combination with nivolumab, in the interest of patient benefit.”

Perspective will host a conference call on Friday, October 11, 2024 at 9am ET to review data contained in the poster at SMR. Details will be available on the Events page of the Company’s website.

About VMT01

Perspective designed VMT01 to target and deliver ²¹²Pb to tumor sites expressing MC1R, a protein that can be overexpressed in metastatic melanoma tumors. The Company is conducting a multi-center, open-label dose escalation, dose expansion study (clinicaltrials.gov identifier NCT05655312) in patients with histologically confirmed melanoma and MC1R-positive imaging scans. In September 2024, the Company announced that the U.S. Food and Drug Administration granted Fast Track Designation for the development of ²¹²Pb VMT01 for the diagnosis and treatment of patients with unresectable or metastatic melanoma and who have demonstrated MC1R tumor expression. The FDA’s Fast Track Designation is one of several approaches utilized by the FDA to expedite development and review of potential medicines for serious conditions and that fulfill unmet medical needs.¹

About Melanoma

Melanoma is a cancer of the skin arising from uncontrollable growth of melanocytes, the melanin producing cells of the body. Metastatic melanoma is the result of melanoma that has progressed through the layers of skin, infiltrated the blood stream or lymphatic system, and traveled to other areas of the body to metastasize. In the United States, there are approximately 100,000 new diagnoses of melanoma annually and approximately 8,300 deaths annually from metastatic melanoma.² Metastatic melanoma has a poor prognosis with limited survival of 50% at 1 year and 25% at 5 years. Recent advances have led to survival improvement, but there remains a high unmet need for additional treatments, particularly for patients with metastatic disease³ who are refractory to front-line therapy.   Median progression free survival (mPFS) for current 2L+ therapies, including lifileucel, remains limited between 2-5 months.^4,5,6

About Perspective Therapeutics, Inc.

Perspective Therapeutics, Inc. is a radiopharmaceutical development company that is pioneering advanced treatment applications for cancers throughout the body. The Company has 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.

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.
