About [²¹²Pb]VMT-α-NET
Perspective designed [212Pb]VMT-α-NET to target somatostatin receptor subtype 2 (SSTR2), and to deliver the alpha-emitting radioisotope lead-212, or ²¹²Pb, to tumor sites expressing SSTR2. The Company is conducting a multi-center, open-label, dose-escalation and dose-expansion study (clinicaltrials.gov identifier NCT05636618) of [212Pb]VMT-α-NET in patients with unresectable or metastatic SSTR2-positive tumors who have not received prior radiopharmaceutical therapies (RPT).
Interim clinical data from the study, with a data cut-off date of April 17, 2026, were presented at the 2026 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in May 2026. These data included efficacy results for half of the patients in Cohort 2 and both patients in Cohort 1. Initial efficacy data for the remaining patients in Cohort 2 and patients in Cohorts 3 and 4 are pending. The Company plans to submit additional data for presentation at future medical conferences in 2026 and 2027.
