PSV359

The Company will present updated preclinical data on PSV359, a novel cyclic peptide targeting fibroblast activation protein-alpha (FAP) and a molecular linker to a lead-specific chelator.

An oral presentation combining first-in-human SPECT/CT images generated by an independent investigator using [203Pb]Pb-PSV359, along with updated analysis of preclinical studies of [212Pb]Pb-PSV359 conducted by the Company, will be presented.

[212Pb]VMT-α-NET for the Treatment of Neuroendocrine Tumors (NETs)

The Company has been informed that two updated analyses based on investigator-led clinical research of [212Pb]VMT-α-NET in India have been accepted for presentation by the EANM conference. The investigator enrolled adult patients with histologically confirmed gastroenteropancreatic neuroendocrine tumors (“GEP-NETs”) and metastatic medullary thyroid carcinomas. The most recent prior public update of this patient series was during the Society of Nuclear Medicine & Molecular Imaging ("SNMMI") Annual Meeting in June 2024.

• The investigator informed the Company that an oral presentation will be provided on the GEP-NET patients as of a later cut-off date than the cut-off date for the SNMMI conference. The analysis presented at SNMMI was based on 10 GEP-NET patients plus 3 patients with other SSTR2+ tumors as of a data cutoff date of May 31, 2024.
• An ePoster to be presented at the conference will focus on the biodistribution and image-guided dosimetric estimates of the [212Pb]VMT-α-NET. Dosimetry data presented during SNMMI was based on two patients.

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.
