Ann: SECuRE trial update, page-18

Clarity’s Executive Chairperson, Dr Alan Taylor, commented,

“The SECuRE trial continues to generate extraordinary results, and we thank our team, Principal Investigators, members of the SRC, and especially the participants who have contributed to the study. Seeing the safety profile and already observing impressive signs of efficacy (despite the majority of participants only receiving a single cycle of 67Cu-SAR-bisPSMA and the primary focus of the Dose Escalation Phase being safety assessments), we are thrilled to progress to Phase II, the Cohort Expansion Phase, of our theranostic SECuRE trial.“Dose escalation trial design has not been routinely used in other RLT studies. By pioneering this approach with the SECuRE trial, Clarity was looking to systematically evaluate the safety of 67Cu-SAR-bisPSMA in the context of its therapeutic effect. By gradually increasing the dose from one cohort to the next, we have minimised the risk of AEs and established a favourable safety profile for patients, while also demonstrating that 67Cu-SAR-bisPSMA is effective.“We are looking forward to executing our strategy of bringing 67Cu-SAR-bisPSMA to earlier lines of prostate cancer therapy with the recent protocol amendment, given the exciting data in pre-chemotherapy participants. We are also increasing the number of participants in the Cohort Expansion Phase.
