SEATTLE, May 20, 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 the Company will present information pertaining to the Company’s sponsored studies of its assets at the Society of Nuclear Medicine & Molecular Imaging (“SNMMI”) Annual Meeting 2024, which is being held in Toronto, Canada, from June 8-11, 2024. The Company notes that results based on investigator-initiated use of its assets are also being presented.
“We are greatly encouraged by the progress of our clinical and preclinical programs," said Thijs Spoor, CEO of Perspective. "The upcoming presentations at the SNMMI meeting will showcase our activities with VMT-α-NET and other promising therapies, underlining our commitment to advancing care for patients battling challenging tumor types.”
[212Pb]VMT-α-NET for the Treatment of Neuroendocrine Tumors
The abstract describing Perspective’s trial in progress of the Phase 1/2a dose escalation study (NCT05636618) in patients with unresectable or metastatic somatostatin receptor type 2 ("SSTR2")-positive neuroendocrine tumors ("NETs") who have not received prior peptide receptor radionuclide therapies (“PRRT”) stated the trial’s status as of January 15, 2024, consistent with the abstract submission deadline for the SNMMI conference. Updates on this trial as of March 7, 2024 were provided during the Company’s investor update on March 18, 2024, accessible on the events page of the Company’s website. This study, in conjunction with the Phase 0 imaging study (NCT05111509), would inform the recommended Phase 2 dose of [212Pb]VMT-α-NET.
Perspective, in collaborating independent investigators, is evaluating dosimetry and the applicability of patient-specific dosing as determined by a target renal absorbed dose for [212Pb]VMT-α-NET. An abstract reported pooled data from ten patients recruited in the Company’s sponsored Phase 0 imaging study and an investigator sponsored absorbed dose escalation study. The investigator reported [212Pb]VMT-α-NET was prescribed to three patients at individualized doses of 5.3, 7.9, and 13.3 mCi (cumulatively, delivered over two cycles) while targeting renal absorbed dose of 3.5Gy. Higher levels of targeted renal absorbed doses are in the protocol for subsequent cohorts of the investigator sponsored study.
The Company has been informed that updated results from the investigator initiated trial of [212Pb]VMT-α-NET in India have been accepted for presentation by the SNMMI conference. The investigator enrolled adult patients with histologically confirmed NETs and metastatic medullary thyroid carcinomas. The investigator informed the Company that the update includes results from 12 patients at a later data cutoff date than previous presentations. The most recent prior public update by the investigator was during the 36th Annual Congress of the European Association of Nuclear Medicine (EANM) in September 2023.
Preclinical Progress on Targeted Therapies for Melanoma and Tumor Environments
The Company will present preclinical data for [212Pb]VMT01, a targeted α-particle radionuclide therapy (α-TRT) targeting the melanocortin 1 receptor (“MC1R”), used in combination with immune checkpoint inhibitors (“ICIs”) in diverse murine melanoma models with high (B16-F10), mid (YUMM-D3) and low (YUMMwt) expressions of MC1R. These data provide a rationale for advancing the combination of [212Pb]VMT01 and ICIs to clinical investigations. The ongoing Phase 1/2a study of [212Pb]VMT01 is being amended to evaluate the safety and tolerability of Perspective’s [212Pb]VMT01 in combination with the ICI nivolumab in patients with histologically confirmed melanoma and MC1R-positive imaging scans.
The final presentation will introduce [203/212Pb]-PSV-359, a novel cyclic peptide developed to target fibroblast activation protein alpha (“FAP”), a protein abundantly expressed by cancer-associated fibroblasts in tumor lesions and involved in promoting disease progression. [203/212Pb]-PSV-359 has a proprietary targeting moiety designed by Perspective to optimize “theranostic” applications, representing a promising avenue for addressing FAP expressing cancers regardless of disease site.
