RICHLAND, WASHINGTON & CORALVILLE, IOWA – August 11, 2023 – Perspective, Therapeutics, Inc. (“Perspective” or “the Company”) (NYSE AMERICAN: CATX), a precision oncology company developing alpha-particle therapies and complementary diagnostic imaging agents and an innovator in seed brachytherapy powering expanding treatment options for multiple cancers, reports second quarter financial results for the period ended June 30, 2023 and recent business highlights.

“We made substantial progress on our pipeline during Q2 2023 with the initiation of Phase 1/2a clinical trials for VMT-𝛼-NET for neuroendocrine tumors and VMT01 for melanoma and we expect preliminary results from initial cohorts by end of the year,” said Thijs Spoor, Perspective Therapeutics’ CEO. “We are supplying both U.S. trials with drug product from our GMP manufacturing facility in Coralville, Iowa. We expect to bring additional CDMO manufacturing sites online in the coming months to enable broader coverage of sites across the U.S. Isotope will be supplied using Perspective’s proprietary VMT-α-GEN 212Pb benchtop generator.”

Andrew Bright, Perspective Therapeutics’ EVP of Brachytherapy noted, “Our brachytherapy business has emerged from the recent merger with an engaged and enthusiastic team that is focused on expanding the use of Cesium-131 brachytherapy. This quarter we have supplemented the team with talent in several key leadership areas. With a strong team in place, we’re focused on securing new business and re-gaining old business. We have a renewed focus on our strategic collaboration with GT Medical Technologies based on a shared belief that Cesium-131 is ideal for delivering radiotherapy to a key group of brain cancer patients. Our sales efforts will be bolstered by long-term Cesium-131 data in prostate cancer and additional peer reviewed data of Cesium-131 use in other cancers.”

Brachytherapy Recent Highlights

  • A favorable comparison between Cesium-131 brachytherapy and Stereotactic Body Radiation Therapy, along with long-term Cesium-131 data, was presented at the American Brachytherapy Society annual meeting. The data showed that Cesium-131 brachytherapy offers prostate cancer patients the prospect of disease-free survival of 96% measured at ten years after treatment.
  • Bander et al. published a retrospective review of brain tumor treatment using surgery and Cesium-131 brachytherapy in the Journal of Neuro-Oncology. The study highlighted the superior local tumor control and lower complication rates of Cesium-131 compared to Iodine-125 data. (Bander, ED, et al., Safety and efficacy of Cesium-131 brachytherapy for brain tumors. Journal of Neurosurgery 163(2): 355-365. (2023)).
  • Established an initiative with GT Medical Technologies, Inc. (GT Medical) to broaden access to their GammaTile® Therapy product, a unique delivery method for placing Cesium-131 during the last five minutes of brain tumor resection surgery.
  • The Centers for Medicare & Medicaid Services announced in July 2023 its proposed Medicare Hospital Outpatient Prospective Payment and Ambulatory Surgical Center Payment Systems payment rates for 2024. Under these rates, Perspective’s stranded pre-loaded Cesium-131 seeds would see an increase in reimbursement per seed. The final rule will be issued in November 2023.

Second Quarter and Half Year 2023 Financial Summary

Revenue – Revenue for the three months ended June 30, 2023 was $2.1 million, as compared to $2.5 million in the same period in 2022, a decline of 17%. The year-over-year decline in revenue was primarily a result of the loss of a large brachytherapy customer partially offset by grant revenue related to our alpha-particle therapy operations.

Gross Profit – Gross profit was $248,000 for the three months ended June 30, 2023, as compared to $926,000 for the same period in 2022, a decline of 73%. The year over year decline was primarily a result of the decrease in sales due to the loss of a large brachytherapy customer, higher brachytherapy production costs, and a $298,000 write-off of Blu Build inventory as the Company discontinued selling its loader, and were partially offset by grant revenue from our alpha-particle therapy business.

Research and development (R&D) expenses – R&D for the three months ended June 30, 2023 and 2022 comparison was an increase in costs of $4.9 million related to the development of the Company’s alpha-particle therapy drug products gained through the merger with Viewpoint, partially offset by a decrease in the Company’s legacy research and development expenses.

Management believes that research and development expenses will increase as we continue to invest in the development of new drugs and products.

Net loss – For the second quarter of 2023, the Company reported a net loss of $11.1 million, compared to a net loss of $2.1 million in the same period in 2022.

About Perspective Therapeutics, Inc.

Perspective Therapeutics, Inc., is a medical technology and radiopharmaceutical company that is pioneering advanced treatment applications for cancers throughout the body. The Company is the sole producer of Cesium-131 brachytherapy seeds and has a proprietary technology that utilizes the isotope Lead-212 to deliver powerful alpha 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 (VMT-01) and neuroendocrine tumor (VMT-α-NET) programs are entering 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 lead-212 generator to secure isotope supply for clinical trial and commercial operations.
