SEATTLE, May 11, 2026 (GLOBE NEWSWIRE) -- Perspective Therapeutics, Inc. ("Perspective," the "Company," "we," "us," and "our") (NYSE:CATX), a radiopharmaceutical development company pioneering advanced treatments for cancers throughout the body, today provided a business update and announced results for the quarter ended March 31, 2026.
"The first quarter of 2026 was marked by continued execution across our clinical programs and strengthening of our financial position," said Thijs Spoor, Perspective's CEO. "Our focus on engineering the alpha advantage across every part of the radiopharmaceutical value chain - from the radioisotope to optimized structural chemistry, theranostic processes, and regional manufacturing - differentiates Perspective, and we look forward to providing clinical and manufacturing updates throughout 2026."
Clinical Highlights
VMT-α-NET
We are conducting a multi-center, open-label, dose-finding 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) who have not received prior radiopharmaceutical therapies (RPT).
- Updated interim data from the study, as of a data cut-off (DCO) date of March 4, 2026, were presented at the American Association for Cancer Research Annual Meeting 2026 in April 2026.
- As of April 30, 2026, the first 23 patients in Cohort 2 have had the opportunity for at least 60 weeks of follow-up since beginning treatment. By late 2026, all 46 patients in Cohort 2 will have had the opportunity for at least 60 weeks of follow-up since beginning treatment.
- We believe our clinical data package positions us for meaningful regulatory engagement in 2026 to align on the path forward.
- As of April 30, 2026, a total of 20 patients have been treated in Cohort 3. This cohort is now closed to enrollment. By late 2026, the eight patients initially enrolled for dose-limiting toxicity (DLT) assessment will have had the opportunity for at least 48 weeks of follow-up since beginning treatment.
- Cohort 4 is now open for recruitment.
- During the dose-finding phase of the study, we enrolled primarily NET patients whose disease originated in the pancreas or the digestive tract. We have an allowance for enrollment of NET patients whose disease originated in the lung (of which small cell lung cancer is a subset), pheochromocytoma/paraganglioma NETs, and SSTR2+ meningioma.
- We opened a proof-of-concept cohort of meningioma patients. To date, there is no approved systematic therapy for this disease. The unmet medical need may support an expedited development path.
VMT01
VMT01 is an MC1R-targeted RPT that can be radiolabeled with either 203Pb for patient selection and dosimetry assessment or 212Pb for alpha-particle therapy. We are conducting a multi-center, open-label, dose-finding study (clinicaltrials.gov identifier NCT05655312) in heavily pre-treated patients with histologically confirmed melanoma and MC1R-positive imaging scans.
- Since dosing re-opened for 3.0 mCi of VMT01 as monotherapy, and was initiated for 3.0 mCi of VMT01 in combination with nivolumab in September 2025, 10 patients had received VMT01 3.0 mCi treatment as of February 28, 2026; six patients had received VMT01 at 3.0 mCi in combination with nivolumab, and four patients had received 3.0 mCi of VMT01 as monotherapy, in addition to the three patients who received this monotherapy dose in late 2023. Both cohorts are now closed for enrollment.
- By late 2026, the 10 patients who had received VMT01 3.0 mCi treatment since the initiation or re-opening of these cohorts in September 2025 will have had the opportunity for at least 24 weeks of follow-up after their initial doses, sufficient time to have completed at least one scan after the full course of treatment (up to three doses every eight weeks).
PSV359
We designed PSV359 to target and deliver 212Pb to tumor sites expressing fibroblast activation protein-α (FAP-α), which is associated with multiple highly prevalent solid tumors, in patients in need of additional treatment options.
- As of April 30, 2026, two patients in Cohort 1 had been treated with [212Pb]PSV359 at 2.5 mCi, and seven patients in Cohort 2 had been treated at 5.0 mCi, for a total of nine patients. By late 2026, these patients will have had the opportunity for at least 32 weeks of follow-up after their initial doses, sufficient time to have completed at least one scan after the full course of treatment (up to four doses every eight weeks).
- Cohort 3 is now open for recruitment.
Updates to the preclinical pipeline
Our discovery team is preparing additional novel constructs for potential first-in-human (FIH) imaging.
- In May 2026, we presented an FIH image for PSV594, designed to target and deliver 212Pb to tumor sites expressing the Cholecystokinin 2 Receptor (CCK2R), which is expressed across a range of hard-to-treat cancers. The targeting moiety may also be radiolabeled with 203Pb or 68Ga to detect CCK2R expression in-vivo. Preclinical and FIH images suggest the targeting moiety has clean, precise tumor uptake with limited kidney retention, which may result in a desirable therapeutic index.
Updates on manufacturing infrastructure
We continue to make progress on expanding our manufacturing capabilities by increasing and enhancing capacity at existing facilities and building out recently acquired sites.
- Our flagship site in the Chicago area is on track to complete construction this year. We are building a complementary site in the Los Angeles area and have plans beyond our current footprint.
First Quarter 2026 Financial Summary
Cash, cash equivalents, and short-term investments as of March 31, 2026, were approximately $271 million as compared to $145 million as of December 31, 2025. In February 2026, we announced the closing of an underwritten offering of securities with net proceeds of approximately $164 million after deducting underwriting discounts and commissions and other offering-related expenses. We believe our cash, cash equivalents, and short-term investments as of March 31, 2026, will be sufficient to fund our current clinical milestones and operational investments into late 2027.
As of March 31, 2026, we had approximately 114.0 million shares of common stock and approximately 20.5 million warrants and options to purchase shares of common stock outstanding. In connection with the February 2026 underwritten offering of securities noted above, we issued 39.6 million shares of common stock along with pre-funded warrants to purchase 6.6 million shares of common stock.
Research and development expenses were $21.4 million for the three months ended March 31, 2026, compared to $14.3 million for the three months ended March 31, 2025, an increase of approximately 50%. The increase in research and development expenses was primarily related to higher personnel costs, including share-based compensation, due to additional headcount to support our ongoing clinical trials, as well as increased spending on contract development and manufacturing organizations, clinical site activities, drug programs and delivery, pipeline studies and consulting.
General and administrative expenses were $7.0 million for the three months ended March 31, 2026, compared to $7.8 million for the three months ended March 31, 2025, a decrease of approximately 10%. The decrease in general and administrative expenses was primarily due to decreased fees for professional and consulting services and fees related to operating as a public company, partially offset by increased personnel costs.
Net loss for the three months ended March 31, 2026, was $26.2 million, or $0.25 per basic and diluted share, compared to a net loss of $18.2 million, or $0.25 per basic and diluted share, for the same period in 2025. During the three months ended March 31, 2026 and 2025, there was a net benefit of $2.1 million and $2.3 million, respectively, in net interest income and other expenses. In addition, during the three months ended March 31, 2025 we recognized $1.4 million of Deferred Income, which was received in 2024.
