VMT-α-NET: Recent Highlights 

Company-sponsored Phase 1/2a trial of [²¹²Pb]VMT-α-NET
Perspective 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 somatostatin receptor type 2 (“SSTR2”)-positive neuroendocrine tumors (“NETs”). The Company received Fast Track Designation for this program from the U.S. Food and Drug Administration (“FDA”) based on preclinical data for the indication of SSTR2-positive NETs regardless of prior treatment response.

• The Company completed dosing for Cohort 1 of its Phase 1/2a study of [²¹²Pb]VMT-α-NET in patients with unresectable or metastatic SSTR2-expressing NETs. As of March 7, [²¹²Pb]VMT-α-NET treatments were well tolerated with no unexpected adverse events. The Safety Review Committee unanimously recommended escalation to Cohort 2.
• Cohort 2 enrollment is progressing well, with four patients already enrolled. Six patients are in screening to complete enrollment.
• The Company currently has seven active sites for the study and is conducting feasibility assessments on additional sites.
• Preliminary results from Cohorts 1 and 2 of the Phase 1/2a trial are expected in the third quarter 2024.

Investigator-Initiated clinical studies of [²¹²Pb]VMT-α-NET
Perspective is collaborating with a number of thought leaders to further elucidate the clinical profile of [²¹²Pb]VMT-α-NET through investigator initiated trials (“IITs”).

• Early clinical results from 10 adult patients, with histologically confirmed NETS and metastatic medullary thyroid carcinomas, who participated in an open-label, single-arm, IIT in India were presented in September 2023 at the 36th Annual Congress of the European Association of Nuclear Medicine (EANM). Highlights of the presented results at EANM included: ten patients who failed at least one prior line of standard of care therapy have received [²¹²Pb]VMT-α-NET therapy to date, with initial responses observed in seven of nine evaluable patients; responses were observed across both peptide receptor radionuclide therapies (“PRRT”)-naïve and PRRT-refractory disease; no significant renal or hepatic function adverse events were observed to date; most adverse events were mild and usually resolved within one week of [²¹²Pb]VMT-α-NET administration; and two patients experienced serious adverse events that were deemed unrelated to [²¹²Pb]VMT-α-NET treatment.

  Further data readout has been submitted to Society of Nuclear Medicine and Molecular Imaging (SNMMI) meeting taking place on June 8 –11, 2024 in Toronto.

• The first patient was dosed at the University of Iowa in a Phase 1 trial evaluating the safety of [²¹²Pb]VMT-α-NET in patients with unresectable or metastatic SSTR2-expressing NETs. The patients being enrolled in the study have either progressed or relapsed after previous therapies, including currently approved PRRT. This is a single site safety study (clinicaltrials.gov identifier NCT06148636) of [²¹²Pb]VMT-α-NET.

  Preliminary data readout is expected in the second half of 2024.

• A publication in the European Journal of Nuclear Medicine and Molecular Imaging showed the first human SPECT images utilizing the alpha-emitting isotope of ²¹²Pb, which labeled the Company’s proprietary theranostic VMT-α-NET product. The imaging was conducted as part of a series of four patients with NETs who were administered VMT-α-NET at a clinical study site at the Technical University of Dresden, Germany. Four patients were treated with  [²¹²Pb]VMT-α-NET and eight patients were imaged with [²⁰³Pb]VMT-α-NET during the second half of 2023. Investigators observed rapid tumor uptake and retention of the drug and patients showed no early or acute side effects.

VMT01: Recent Highlights
Perspective designed VMT01 to target and deliver ²¹²Pb to tumor sites expressing melanocortin 1 receptor (“MC1R”), a protein that is overexpressed in melanoma cancers. The Company is conducting a multi-center, open-label dose escalation, dose expansion study (clinicaltrials.gov identifier NCT05655312) in subjects with histologically confirmed melanoma and MC1R-positive imaging scans.

• The Company completed dosing for Cohort 1 of the Phase 1/2a clinical study of [²¹²Pb]VMT01 in patients with progressive MC1R-positive metastatic melanoma. As of March 7, [²¹²Pb]VMT01 was well tolerated with no unexpected adverse events. The Safety Review Committee unanimously recommended escalation to Cohort 2.
• Cohort 2 enrollment is progressing well, with two patients already enrolled. Four patients are in screening.
• The Company currently has eight active sites for the study and is assessing the feasibility of other potential sites.
• Preliminary safety and efficacy results from Cohorts 1 and 2 of the Phase 1/2a study are expected in the third quarter 2024.
• In March 2024, the Company entered a clinical trial collaboration agreement with Bristol Myers Squibb (NYSE: BMY) to evaluate the safety and tolerability of Perspective’s [²¹²Pb]VMT01 in combination with Bristol Myers Squibb’s nivolumab in patients with histologically confirmed melanoma and positive MC1R imaging scans. The combination study is an amendment to the Company’s ongoing Phase 1/2a study of [²¹²Pb]VMT01 in patients with metastatic melanoma.

PSV40X: A Different PSMA-Targeted Radiohybrid Molecule

• In December 2023, the Company entered into a patent license agreement with Mayo Clinic for the rights to Mayo’s PSMA Alpha-PET DoubLET platform technology for the treatment of PSMA-expressing cancers, with an initial focus on prostate. This radiopharmaceutical platform provides detailed PET imaging-based diagnosis and dosimetry using long-lived copper-64 (⁶⁴Cu) for imaging and alpha-particle targeted therapies using ²¹²Pb.

Brachytherapy: Recent Highlights

• During the fourth quarter of 2023, the Company announced the sale of its brachytherapy business, including its radioactive Cesium-131 seed assets and related business infrastructure, to GT Medical Technologies, Inc. The transaction is expected to close in the first half of 2024.

Subsequent Business Highlights 

• In January 2024, Perspective Therapeutics entered into strategic agreements with Lantheus Holdings, Inc. and its affiliates (“Lantheus”) (NASDAQ: LNTH). Under the agreements, Lantheus will have the option to negotiate an exclusive license to Perspective’s [²¹²Pb]VMT-α-NET. Lantheus will also have the option to co-fund and negotiate an exclusive license for certain early-stage therapeutic candidates targeting prostate cancer using Perspective’s lead platform technology.
• In February 2024, Perspective announced it entered into an exclusive license agreement with Stony Brook University for the rights to its Cuburbit[7]uril-admantane (“CB7-Adma”) pre-targeting platform for the diagnosis and treatment of cancer. The exclusive license with Stony Brook University covers the global intellectual property rights for the CB7-Adma pre-targeting platform. The Company has applied for the Phase I tranche of a 2.5-year Fastrack Small Business Innovation Research grant (Phase I $400,000; total $2.4 million) from the National Institutes of Health National Cancer Institute to support the development of the pre-targeting program.
• In March 2024, the Company announced its next therapeutic candidate, PSV359. PSV359 targets fibroblast activation protein-α (“FAP-α”) for the treatment of solid tumors. The Company presented data which included analysis of a first-in-human study, under the direction of Dr. Dharmender Malik of Fortis Memorial Research Institute, evaluating the suitability of [²⁰³Pb]PSV359 for SPECT/CT imaging of patients with lung adenocarcinoma, NETs, and chrondroblastic osteosarcoma. Perspective is working to file an IND application in late 2024 for this new program.
• In March 2024, the Company acquired a state-of-the-art radiopharmaceutical manufacturing facility and associated equipment and systems for the production of its ²⁰³Pb- and ²¹²Pb-labeled radiopharmaceuticals in Somerset, New Jersey.

Fiscal Year 2023 Financial Summary 

The Company has previously presented its results in two segments: Drug Operations and Brachytherapy. Due to the divestiture of its entire brachytherapy segment to GT Medical, the assets and operations of the brachytherapy segment have been classified as discontinued operations in the Company’s financials. The comments below pertain to our continuing operations unless otherwise noted.

Grant revenues were $1.4 million for the year ended December 31, 2023 compared to no grant revenues in the prior year.

Research and development expenses were $21.3 million for the year ended December 31, 2023 compared to $0.9 million for the same period in 2022, an increase of $20.4 million. Management continues to believe that research and development expenses may increase as the Company continues to advance its clinical programs. 

Total operating expenses for the year ended December 31, 2023 were $42.4 million, compared to $8.7 million for the year ended December 31, 2022, an increase of 387%.

Net loss for the year ended December 31, 2023 was $46.5 million or $(0.17) per basic and diluted share, compared to a net loss of $10.8 million or $(0.08) per basic and diluted share for the year ended December 31, 2022. The 2023 net loss figure includes $40.1 million in loss from continuing operations and $9.1 million in loss from discontinued operations offset partially by deferred income tax benefit of $2.7 million.

Cash and cash equivalents as of December 31, 2023, was $9.2 million as compared to $21.0 million on December 31, 2022. During the first quarter of 2024, Perspective raised aggregate gross proceeds of $20.8 million in a January 2024 private placement, $69.0 million in a January 2024 public offering, and $87.4 million in a March 2024 private placement before deducting underwriting fees, placement agent fees, and other expenses. We believe that our cash and cash equivalents as of December 31, 2023 and the cash we raised through the January 2024 private placement and public offering and the March 2024 private placement will be sufficient to fund our operations and capital investments into 2026.

As of March 22, 2024, the number of common shares outstanding was 586,915,977.
