Clarity Pharmaceuticals Shares Updates on SECuRE Trial
HIGHLIGHTS
In a recent assessment of the Cohort Expansion Phase (Phase II) of the SECuRE trial conducted by the Safety Review Committee (SRC), it has been confirmed that the trial will proceed without any alterations to the existing protocol. This decision follows an interim review of collected data, which continues to demonstrate encouraging results.
Trial's Patient Population
The SECuRE trial, currently active in participant recruitment, has included nine individuals with evaluable data. By the interim analysis cutoff date, this cohort consisted of participants who had received at least two cycles of 8 GBq of 67Cu-SAR-bisPSMA. Most of these individuals had previously undergone multiple rounds of cancer treatment, highlighting the trial's focus on heavily pre-treated patient populations.
Patient Characteristics and Treatment
Out of the nine participants included, seven were administered 67Cu-SAR-bisPSMA, while two received it in conjunction with enzalutamide. Notably, 55.6% of participants had experienced over five prior anti-cancer regimens, and 66.7% were diagnosed with bone metastasis.
Safety Profile Assessment
The safety evaluation of 67Cu-SAR-bisPSMA indicates a favorable profile, as the majority of reported adverse events (AEs) during the Cohort Expansion remained low in severity, predominantly categorized as Grade 1 or 2. Common AEs included nausea and lymphopenia, each occurring in 33.3% of participants.
Efficacy Observations
Among the participants, six provided at least two prostate-specific antigen (PSA) results post-treatment. All showed declines in PSA levels, with four participants (66.7%) achieving over a 50% reduction (PSA50), and two reported reductions exceeding 80% (PSA80). In particular, one participant with bone metastasis achieved undetectable PSA levels following treatment, without any prostate cancer detectable via imaging studies, signifying an exceptional clinical outcome.
Future Directions of the SECuRE Trial
As the SECuRE trial continues to move forward, recruitment efforts into the Cohort Expansion Phase are set to conclude in 2026. Plans for a Phase III registrational trial are underway, informed by the promising data accrued thus far.
Clarity Pharmaceuticals, a clinical-stage radiopharmaceutical company devoted to advancing treatment options for cancer patients, is excited to communicate these updates regarding the SECuRE trial. Their innovative approach aims to enhance patient outcomes through cutting-edge therapeutic solutions.
Executive Insights
Dr. Alan Taylor, Executive Chairperson at Clarity, expressed optimism about the ongoing developments, noting the trial's successful data generation and the promising safety and efficacy outcomes. He highlighted how the proprietary SAR-bisPSMA technology, combining therapeutic and diagnostic applications, shows the potential to transform treatment options in prostate cancer.
About the SECuRE Trial
The SECuRE trial is designed as a Phase I/IIa investigation aimed at confirming the efficacy and safety of 67Cu-SAR-bisPSMA in targeting PSMA-expressing metastatic castration-resistant prostate cancer (mCRPC). This trial is a multi-center, single-arm, dose escalation study, which aims to enroll approximately 54 participants across multiple sites. The overarching goal is to establish the benefits of 67Cu-SAR-bisPSMA therapy in the treatment phase.
