[212Pb]VMT-α-NET therapy in somatostatin receptor 2 (SSTR2) expressing neuroendocrine tumors (NETs): Dose-limiting toxicity (DLT) observation participants after 1 year follow-up and preliminary report for expansion participants
About [212Pb]VMT-α-NET Perspective designed [212Pb]VMT-α-NET to target and deliver 212Pb to tumor sites expressing SSTR2. The Company is conducting a multi-center, open-label dose escalation, dose expansion study (clinicaltrials.gov identifier NCT05636618) of [212Pb]VMT-α-NET in patients with unresectable or metastatic SSTR2-positive neuroendocrine tumors who have not received prior radiopharmaceutical therapies (RPT). Results with a data cut-off date of January 10, 2025 from the first nine patients enrolled into Cohorts 1 and 2 of the study were most recently presented as a poster at the American Society of Clinical Oncology Gastrointestinal Cancers Symposium (ASCO-GI) in January 2025. Cohort 2 was reopened in August 2024. By 3Q and 4Q 2025, patients enrolled after the cohort reopened and through February 28, 2025, will have had the opportunity for at least 32 weeks of follow-up after their initial doses, sufficient time to receive at least one scan after their full treatment (up to four doses every eight weeks), if they receive all four doses of treatment per protocol.
About [212Pb]VMT01 Perspective designed [212Pb]VMT01 to target and deliver 212Pb to tumor sites expressing MC1R, a protein that can be overexpressed in metastatic melanoma tumors.1 The Company is conducting a multi-center, open-label dose finding, dose expansion study (clinicaltrials.gov identifier NCT05655312) in patients with histologically confirmed melanoma and MC1R-positive imaging scans. Initial results as of a data cut-off date of September 4, 2024 were previously presented at the 21st International Congress of the Society for Melanoma Research (SMR) in October 2024. Two additional cohorts commenced patient treatment in March and April 2025, of [212Pb]VMT01 in combination with the immune checkpoint inhibitor nivolumab, and as monotherapy, respectively.
About Perspective Therapeutics, Inc. Perspective Therapeutics, Inc. is a radiopharmaceutical development company pioneering advanced treatments 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 moieties. The Company is also developing complementary imaging diagnostics that incorporate the same targeting moieties, which provides 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 are in Phase 1/2a imaging and therapy trials in the U.S. for the treatment of metastatic melanoma and neuroendocrine tumors, respectively. The Company is growing its regional network of drug product finishing facilities, enabled by its proprietary 212Pb generator, to deliver patient-ready products for clinical trials and commercial operations.
