PROCEPT Announces 5-Year WATER Study Data Comparing Aquablation to TURP

– Symptom reduction and uroflow improvement proved durable and consistent compared to TURP

– Larger prostates (≥50 ml) demonstrated a larger safety and efficacy benefit for Aquablation over TURP

– 5-year Aquablation retreatment rate was 51% less compared to TURP

REDWOOD CITY, Calif., Feb. 14, 2022 (GLOBE NEWSWIRE) -- PROCEPT BioRobotics Corporation (Nasdaq: PRCT), a surgical robotics company focused on advancing patient care by developing transformative solutions in urology, today announced positive five-year results from its 181 patient randomized WATER study comparing Aquablation therapy to TURP, the historical standard of care for treating BPH.

WATER is the only prospective, randomized, double-blind, multicenter FDA pivotal study comparing the safety and efficacy of Aquablation to TURP. The study proved superior safety due to low irreversible complications and also superior symptom relief for prostates in the range of 50 milliliters or greater.

At five years, IPSS scores improved by 15.1 points in the Aquablation group and 13.2 points in TURP (p=.2764). However, for men with larger prostates greater than 50 milliliters, IPSS reduction was 3.5 points greater across all follow-up visits in the Aquablation group compared to the TURP group (p=.0123). Improvement in peak urinary flow rate was 125% and 89% compared to baseline for Aquablation and TURP, respectively. Retreatment rates, defined as needing BPH medication or surgical intervention, was approximately 1% per year for Aquablation, which was a 51% reduction compared to TURP.

“The urological community has been waiting to see if the early, pronounced benefits from Aquablation would remain over time. With the 5-year data from a randomized study now available, the Aquablation results are quite durable and look to have a very low rate of men needing an additional treatment. Given the broader range of prostate size and anatomy Aquablation can treat, this technology has the potential to change the paradigm of how BPH is treated,” said Dr. Alexis E. Te¹, Professor of Urology at the Weill Medical College at Cornell University.

“Based on our 5-year WATER data and real-world experience, we believe Aquablation therapy is poised to become the treatment of choice for BPH as it addresses the compromise between safety and efficacy. This study reinforces the durability of Aquablation therapy, and we are thrilled that men everywhere suffering from BPH now have a surgical treatment option with proven clinical outcomes, independent of the size and shape of the prostate, and a reduced risk of sexual side effects,” said Reza Zadno, President and Chief Executive Officer of PROCEPT BioRobotics.

About PROCEPT BioRobotics Corporation

PROCEPT BioRobotics is a surgical robotics company focused on advancing patient care by developing transformative solutions in urology. PROCEPT develops, manufactures and sells the AquaBeam Robotic System, an advanced, image-guided, surgical robotic system for use in minimally-invasive urologic surgery with an initial focus on treating benign prostatic hyperplasia, or BPH. BPH is the most common prostate disease and impacts approximately 40 million men in the United States. PROCEPT designed Aquablation therapy to deliver effective, safe and durable outcomes for males suffering from lower urinary tract symptoms, or LUTS, due to BPH that are independent of prostate size and shape or surgeon experience. PROCEPT has developed a significant and growing body of clinical evidence, which includes nine clinical studies and over 100 peer-reviewed publications, supporting the benefits and clinical advantages of Aquablation therapy.
