Calyxo, Inc. Reveals ASPIRE Study Results on Kidney Stone Treatment

Groundbreaking Results from the ASPIRE Study

Calyxo, Inc., a forward-thinking medical device company, proudly announces significant outcomes from their ASPIRE clinical trial. The study, recently published in the respected Journal of Endourology, highlights the remarkable effectiveness of the SURE procedure using the CVAC Aspiration System for kidney stone clearance. Initial findings reveal that the SURE method outperforms traditional ureteroscopy in both stone clearance and residual stone volume.

ASPIRE Trial Overview

The ASPIRE trial, which stands for ASPiration to Improve Renal Calculi Removal Effectiveness, is a pivotal exploration into new methods of treating kidney stones. This multi-center, randomized, non-inferiority study involved 101 patients treated across 11 institutions. Participants were split between those receiving the innovative SURE procedure and those undergoing standard ureteroscopy from mid-2021 through early 2023.

Key Findings and Statistical Insights

Results from the trial indicate that the SURE procedure resulted in a significantly higher rate of stone clearance. The mean reduction in stone volume was an impressive 97% for patients utilizing the SURE method, compared to 93% for those receiving standard ureteroscopy. Notably, the residual stone volume (RSV) was also lower in patients who underwent the SURE procedure, bringing the mean RSV down to 14.3 mm³, while the traditional URS treatments recorded a significantly higher mean RSV of 70.2 mm³. These findings are statistically significant, demonstrating the superior efficacy of the CVAC System in kidney stone treatment.

Benefits of the CVAC Aspiration System

Dr. Brian R. Matlaga, lead author of the study and Professor of Urology at Johns Hopkins University, emphasized the advantages of the new technology. He noted that the CVAC aspiration system maintains high efficacy even with larger baseline stone volumes. This is contrary to traditional ureteroscopy, where treatment efficacy tends to diminish as the stone size increases, potentially leading to complications for the patient.

Progress in Measuring Treatment Success

One noteworthy aspect of the ASPIRE study is its approach to defining success in kidney stone treatment. Rather than relying solely on the stone-free rate (SFR), which can often be inconsistent due to variable reporting standards, the study utilized continuous measures such as stone clearance percentages and absolute residual stone volume. This more refined approach results in a clearer understanding of treatment efficacy and its clinical significance.

Future Implications for Kidney Stone Treatment

Joe Catanese, the President and CEO of Calyxo, expressed optimism about the implications of the ASPIRE results. The findings are expected to ignite further research into kidney stone treatments while highlighting the CVAC System's capabilities within the medical community. With its FDA clearance, the CVAC System is now recognized as a minimally invasive alternative designed for effective kidney stone removal.

Understanding Kidney Stones

Kidney stones affect approximately 10% of the population at some point in their lives, leading to significant pain and healthcare expenses. The healthcare costs associated with treating kidney stones are substantial, with projections indicating that direct treatment costs may reach $4.1 billion annually by 2030.
