Perspective Therapeutics Reports Third Quarter Fiscal 2023 Results and Recent Business Highlights

SEATTLE, Nov. 14, 2023 (GLOBE NEWSWIRE) — Perspective Therapeutics, Inc. (NYSE AMERICAN: CATX), today announced third quarter financial results for the period ended September 30, 2023 and provided recent business highlights.. 

“Our commitment to advancing targeted alpha-particle therapies against neuroendocrine tumors remains steadfast as we have completed dosing of the first patient in the Phase 1/2a clinical trial of [²¹²Pb]VMT-α-NET,” said Thijs Spoor, Perspective Therapeutics’ CEO. “In addition, we completed recruitment for the first patient cohort in the Company-sponsored Phase 1/2a dose escalation/dose expansion clinical trial evaluating [²¹²Pb]VMT01 for the treatment of histologically confirmed melanoma. We are nearing completion of the imaging portion of the clinical trial evaluating the suitability of [²⁰³Pb]VMT01 for SPECT/CT imaging.”

“We are pleased with our execution this quarter and continue to see positive momentum in the number of patients being treated with Cesium-131 each month, marking a return to growth as compared to the same period in the prior year,” stated Andrew Bright, Perspective Therapeutics’ Executive Vice President of Brachytherapy. “The rebound in the number of patients treated was driven by engagement with current customers, as well as new customers adopting Cesium-131 in their brachytherapy programs. Additionally, increased utilization of Cesium-131 is evident in our core prostate business, as well as in other disease areas, notably lung and brain brachytherapy.”

VMT-α-NET Recent Highlights 

Company-sponsored Phase 1/2a clinical trial of [²¹²Pb]VMT-α-NET

• Dosed first patient in the Phase 1/2a clinical trial of [²¹²Pb]VMT-α-NET for unresectable or metastatic SSTR2-expressing neuroendocrine tumors (NETs) at Washington University in St. Louis.
• The Company currently has two active sites for the clinical trial and anticipates that two additional clinical trial sites will become operational in December.
• The Company remains on track to launch an additional 14 clinical trial sites.

Investigator-Initiated clinical trials of [²¹²Pb]VMT-α-NET

• Presented early clinical findings at the 36th Annual Congress of the European Association of Nuclear Medicine (EANM) for the Phase 2a clinical trial of [²¹²Pb]VMT-α-NET in pre- and post-Lutathera gastroenteropancreatic (GEP)-NET patients, being conducted at Fortis Healthcare, India. Dr. Dharmender Malik of Fortis Memorial Research Institute presented data on [²¹²Pb]VMT-α-NET therapy in 10 patients who had failed prior treatment, including standard care. Initial data readout demonstrated high objective response rate for 7 of 9 evaluable patients, spanning peptide receptor radionuclide therapy (PRRT)-naïve and PRRT-refractory cases. Two additional patients were enrolled in the third quarter for a total of 9 GEP-NET patients and 2 medullary thyroid cancer (MTC) patients. All ongoing patients are expected to complete their 4th treatment cycle by the end of February 2024. Updated clinical results are expected to be presented at an upcoming scientific meeting in 2024.
• Two patients were screened in the Phase 1/2a clinical trial for post-Lutathera GEP-NET patients at the University of Iowa. A third patient is scheduled for screening mid-November. If eligible, all three patients will receive treatment in December for the completion of the first cohort. The end of fourth cycle of treatment is expected in June 2024.
• End-of-life compassionate use program for patients with advanced NETs and lack of further treatment options is underway at the University Dresden in Germany. Four patients were treated during the third quarter, and investigators are planning additional treatments before the end of the year.
• IND submissions are expected in November with subsequent trial activation in the first half of 2024 for NIH-sponsored studies in pre- and post-Lutathera NET patients.

VMT01 Recent Highlights

• Completed recruitment for the first patient cohort in the Company-sponsored Phase 1/2a dose escalation/dose expansion clinical trial of [²¹²Pb]VMT01 in patients with histologically confirmed melanoma and positive MC1R imaging scans. Three patients have been dosed at 111 MBq (3mCi), closing cohort 1. No serious adverse events or dose-limiting toxicities have been observed. The Company anticipates opening the second patient cohort, which will receive 185 MBq (5mCi) per dose, in December 2023 and anticipates the completion of screening in the first quarter of 2024.
• Nearing completion of analysis of the dosimetry portion of the Company’s TIMAR-1 clinical trial, a first-in-human study evaluating the suitability of [²⁰³Pb]VMT01 for SPECT/CT imaging and [⁶⁸Ga]VMT02 for PET/CT imaging of MC1R-expressing metastatic melanoma. Perspective is actively working on the Clinical Study Report and anticipates it will be released in the first half of 2024.

Brachytherapy Recent Highlights

• Third quarter 2023 revenue was the highest since the second quarter of 2022, with a return to growth over the third quarter of 2022.
• Appointed sales, marketing and clinical team members along with a senior customer service representative to supplement Perspective’s dedicated commercial team.
• Launched marketing initiatives to increase direct patient communication and engagement on Cesium-131 brachytherapy.
• Facilitated timely access to GT Medical’s GammaTile for challenging brain cancers through increased production of Cesium-131 brachytherapy seeds that allowed GT Medical to address short notice orders with increased confidence.
• Presented long-term data for Cesium-131 brachytherapy in the treatment of prostate cancer at the American Society for Radiation Oncology (ASTRO) annual conference. In his presentation, Dr. Mohamed Abdelhakiem of the UPMC Hillman Cancer Center described urinary data collected from 341 patients treated with Cesium-131 between 2006 and 2022.
• Presented preliminary long-term data for Cesium-131 utilized in salvage treatment of recurrent cervical and uterine cancers at the ASTRO annual conference. Dr. Zeta Chow of the University of Kentucky showed data that indicated Cesium-131 brachytherapy is a promising alternative to pelvic exenteration, a significant surgical procedure.
• Publication of peer reviewed article in the journal of Brachytherapy highlighting Cesium-131 clinical data from Dr. Benoit and colleagues at the University of Pittsburgh School of Medicine. The results support Cesium-131 and provide additional data on dose parameters for improved urinary side effect profile without affecting disease free survival.

Discovery Program Milestones 

• Presented data at EANM. Dijie Liu, Principal Research Scientist at Perspective, presented mouse model data highlighting the efficacy of [^203/212Pb]VMT-α-NET in treating metastatic neuroblastoma tumors. The study showed successful tumor uptake via sequential SPECT imaging and demonstrated a maximum tolerated dose of [²¹²Pb]VMT-α-NET as 2.22 MBq without acute toxicity, with a 100% overall survival rate at 90-days observed in the group receiving three fractionated doses of 740 kBq of [²¹²Pb]VMT-α-NET.
• Presented collaborative data at the World Molecular Imaging Congress. Dr. Michael K. Schultz, Chief Science Officer of Perspective presented data highlighting the effectiveness of [²¹²Pb]VMT-α-NET in treating neuroendocrine tumors in a tumor xenograft mouse model. The results highlighted the significant therapeutic efficacy of treatment with three fractionated doses of [²¹²Pb]VMT-α-NET, which resulted in a 70% complete response rate and 80% survival at 120 days.
• Presented encouraging data on novel guest/host platform for effective in vivo image-guided pre-targeted alpha particle therapy at the World Molecular Imaging Congress. Dr. Amritjyot Kaur of Stony Brook University showed that the radioligand [²⁰³Pb]PSC-PEG3-Adma demonstrated extended lag times, impressive tumor-to-tissue ratios and has the potential to further reduce radiation toxicity using [²⁰³Pb]PSC-PEG3-Adma as a guide.
• Publication of a peer-reviewed article in Nuclear Medicine and Biology reporting on collaborative research with the University of Alberta, to accelerate the availability of imaging surrogate isotope Pb-203 for image-guided dosimetry planning of Pb-212 labeled radiopeptide conjugates. The collaboration has established an approach to production that can be readily adopted by other cyclotron facilities that produce high yields and excellent specific activity.
