Robotic Radical Prostatectomy Comes Up ‘Short’ in CAPTAIN Trial
Rhea-AI Summary
Profound Medical (NASDAQ:PROF; TSX:PRN) reported new Level 1 post-market data from the randomized CAPTAIN trial comparing the TULSA Procedure™ with robotic radical prostatectomy in men with organ-confined, intermediate-risk Gleason 7 prostate cancer.
At 1 month, there was no median change in penile length after whole-gland TULSA, versus a median 0.65 cm reduction after robotic RP. According to Profound, a mixed-effects model showed a 0.42 cm between-arm difference (p<0.001), favoring TULSA. The company positions these results as additional quality-of-life context to previously disclosed CAPTAIN primary safety data, where TULSA demonstrated statistically significant superiority over robotic RP in preserving erectile function and urinary continence at 6 months.
CAPTAIN is a prospective, multi-center randomized trial that ultimately treated 211 patients across 23 sites. Its primary endpoints assess preservation of erectile potency and urinary continence at 1 year and cancer control outcomes at 3 years.
Positive
- No median penile length change at 1 month after TULSA vs 0.65 cm reduction after robotic RP
- Statistically significant penile length difference of 0.42 cm favoring TULSA (p<0.001)
- CAPTAIN randomized trial treated 211 patients across 23 sites by August 2025
- Prior CAPTAIN data: TULSA showed statistically significant superiority in preserving erectile function and urinary continence at 6 months
Negative
- None.

– Whole-gland TULSA ablation demonstrates statistically significant superior penile length preservation compared to robotic RP at 1 month –
TORONTO, July 24, 2026 (GLOBE NEWSWIRE) -- Profound Medical Corp. (NASDAQ:PROF; TSX:PRN) (“Profound” or the “Company”), a commercial-stage medical device company that develops and markets innovative interventional MRI (iMRI) procedures, today announced new data from the Level 1 post-market CAPTAIN randomized controlled trial comparing the TULSA Procedure™ with robotic radical prostatectomy (“robotic RP”) in men with organ-confined, intermediate-risk, Gleason Score 7 (Grade Group 2 and 3) prostate cancer. At 1 month following the TULSA Procedure, there was no median change in penile length, compared with a median 0.65 cm reduction in penile length after robotic RP.
The new penile length results in favor of the TULSA Procedure were presented for the first time earlier today by Xiaosong Meng, MD, PhD, an Assistant Professor in the Department of Urology at UT Southwestern Medical Center, at the Society of Robotic Surgery (“SRS”) Annual Meeting held in Fort Lauderdale, FL.
Dr. Meng’s SRS presentation highlighted:
- No median change in penile length at 1 month after whole-gland TULSA, compared with a median 0.65 cm reduction in penile length after robotic RP.
- A statistically significant between-arm difference in change in penile length estimated from a mixed-effects model (0.42 cm; p<0.001).
- Additional quality of life context following Profound’s previously announced CAPTAIN primary safety endpoint results, in which TULSA demonstrated statistically significant superiority over robotic RP in preserving both erectile function and urinary continence at 6 months.
“Penile length is not something many men feel comfortable talking about, even in the absence of prostate disease,” said Arun Menawat, Profound’s CEO and Chairman. “Because the penis may be deeply tied to their identity, masculinity, and/or self-worth, even small amounts of penile shrinkage can cause men a lot of additional worry and distress. This new data points to the greater peace of mind that the TULSA Procedure can deliver to patients by gently, safely and precisely ablating prostate tissue while actively protecting surrounding structures.”
About CAPTAIN
CAPTAIN (A Comparison of TULSA Procedure vs. Radical Prostatectomy in Participants with Localized Prostate Cancer) is a prospective, multi-center randomized controlled trial aimed at comparing the safety and efficacy of the TULSA Procedure (performed with the TULSA-PRO® system) with robotic RP in men with organ-confined, intermediate-risk, Gleason Score 7 (Grade Group 2 and 3) prostate cancer. CAPTAIN exceeded its enrollment target, treating 211 patients, instead of the initially planned 201 patients, by August 2025 at 20 sites in the United States, two in Canada and one in Europe. The goal of CAPTAIN is to demonstrate that the efficacy of the TULSA procedure is not inferior to robotic RP, while demonstrating superior quality of life outcomes. The primary safety endpoint is the proportion of patients who preserve both erectile potency and urinary continence at one year after treatment. The primary efficacy endpoint is the proportion of patients who are free from any additional treatment for prostate cancer, free of metastases or prostate cancer related death by three years after treatment. Secondary endpoints include comparison of rates of complications, cost effectiveness, as well as histologic and biochemical failure.
About Profound Medical Corp.
Profound is a commercial-stage medical device company and an innovator in interventional MRI (iMRI) procedures. The company’s flagship platform, TULSA-PRO®, enables MRI-guided, incision-free prostate ablation. Physicians use the TULSA Procedure™ to see, ablate, and confirm therapy in real time, supporting personalized treatment strategies across the continuum of prostate care—from whole-gland to subtotal, hemi, multifocal, and focal treatment. This approach enables individualized care using prostate tissue ablation, while minimizing the potential of the side effects that are typically associated with surgery or radiation, such as urinary incontinence and/or erectile dysfunction.
Profound also commercializes Sonalleve®, an MRI-guided therapy that provides a non-surgical treatment option for pain palliation of bone metastases, desmoid tumors, and osteoid osteoma, as well as for common gynecologic conditions including uterine fibroids and adenomyosis. Sonalleve delivers targeted therapy with no incisions, no blood loss during the procedure, no overnight hospital stay, and faster recovery — and, in gynecologic applications, enables uterine-sparing treatment that may help preserve fertility. Profound is also exploring additional clinical applications for Sonalleve, including non-invasive ablation of abdominal cancers and hyperthermia-based cancer therapies.
Profound Medical’s technologies are approved across major global markets. TULSA-PRO is cleared by the FDA in the United States for transurethral ultrasound ablation (TULSA) of prostate tissue. In addition, TULSA-PRO is cleared for use in various jurisdictions including Europe, Canada, Saudi Arabia, India, Australia/New Zealand, and the UAE. Sonalleve is approved by the FDA as HDE in the United States for the treatment of osteoid osteomas in the extremities. Sonalleve is also cleared or approved in the Europe, Canada, China, and Saudi Arabia.
Through real-time MRI guidance and data-driven innovation, Profound is advancing the future of MRI-guided therapy — expanding access to precise, personalized, and incision-free treatment options worldwide.
