Focal One focuses high-intensity ultrasound waves on affected areas, destroying most cancers cells within the gland with out damaging the wholesome surrounding tissue. | Supply: EDAP
Earlier this 12 months, EDAP TMS SA introduced the complete outcomes of a HIFI examine evaluating the high-intensity centered ultrasound, or HIFU, therapy of localized prostate most cancers. The examine in contrast the French firm’s robotic Focal One system in opposition to radical prostatectomy, or RP, surgical procedure as the primary line of therapy.
HIFI was the primary potential, multicenter, non-inferiority comparative examine evaluating HIFU and RP within the administration of prostate most cancers. It discovered that Focal One’s therapy strategies match up with the gold star customary of surgical procedure, stated EDAP. The corporate claimed that the robotic therapy can enhance quality-of-life outcomes for these fighting prostate most cancers.
These quality-of-life adjustments, like a decreased fee of urinary incontinence or lack of erectile perform, are what introduced Ryan Rhodes to EDAP as its CEO. Beforehand, Rhodes spent over 13 years of his profession at Intuitive Surgical. There, he noticed how addressing prostate most cancers had on Intuitive as a enterprise.
In only a 12 months, he stated, radical prostatectomies carried out with Intuitive’s Da Vinci system drove that firm to profitability. Nevertheless, each surgical procedure comes with dangers, even with robotics, acknowledged Rhodes.
“Figuring out that, even within the arms of robots and doing nice surgical procedure, there was at all times the danger of uncomfortable side effects, as a result of the surgical procedure continues to be surgical procedure, whether or not it’s achieved with a robotic or not,” he instructed The Robotic Report. “What we noticed was that males endure from lack of sexual perform, lack of urinary management, and even in some situations, and we don’t at all times get the most cancers out.”
“Round 2015, there was a whole lot of dialogue about overtreating prostate illness with radical surgical procedure, regardless of the danger of uncomfortable side effects, Rhodes added. “Now, we will higher risk-stratify sufferers, and there are different choices moreover radical surgical procedure, resembling Focal One, which makes use of advances in imaging and may import biopsy knowledge for the surgeon to arrange a goal plan for guided precision ablation.”

Focal One supplies a non-surgical various
Focal One stated its HIFU Robotic System makes use of high-performance imaging and HIFU expertise to permit urologists to focus on the prostate with submillimeter accuracy. This enables them to spare wholesome, surrounding tissue and protect the affected person’s high quality of life, the corporate stated.
Rhodes emphasised that even when surgeons use robots, surgical procedure continues to be surgical procedure. “Reducing, coagulating, suturing, ranking traction, and damage — all this stuff occur throughout surgical procedure,” he stated. “In our [non-invasive] strategy, there is no such thing as a surgical procedure, no blood loss, no slicing, no radiation.”
As a result of Focal One doesn’t require a doctor to carry out surgical procedure, it may do procedures in an outpatient setting. With only a urologist, an anesthesiologist, and a nurse, hospitals can carry out HIFU procedures that take simply 40 to 60 minutes, Rhodes stated. This may tremendously scale back staffing calls for that many hospitals are already fighting.
“That advantages all people, and positively urologists recognize that profit,” stated Rhodes. “As a result of there’s no surgical procedure concerned, there’s no surgical fatigue.”
“Physicians can work with imaging they’re accustomed to, utilizing the identical ultrasound expertise they used to carry out a biopsy on the affected person,” he added. “In lots of instances, they have been those who did the biopsy on the affected person, in order that they keep in mind areas of curiosity, the place the most cancers is, and the borders of that most cancers.”
A lot of the time, surgical procedure is sort of a puzzle, Rhodes defined. Physicians usually go into surgical procedures with out figuring out precisely what to anticipate. Focal One is meant to takes away a lot of that uncertainty, with a five-axis robotic.
HIFI examine finds favorable outcomes
The seven-year examine, which came about from April 2015 to March 2022, enrolled a complete of three,328 sufferers from 46 therapy facilities. 1,967 consecutive sufferers have been handled with EDAP’s robotic HIFU applied sciences. The French ministry of well being funded the examine with $20 million.
Physicians used Focal One for 90% of the sufferers, and 1,361 sufferers underwent radical prostatectomy surgical procedure. All sufferers have been adopted for 30 months. The outcomes have been printed within the journal European Urology.
At 30 months, the adjusted salvage treatment-free survival (STFS) was greater within the HIFU arm (90%) in contrast with the RP arm (86%). After adjusting for various variables, together with age, physique mass index, American Society of Anesthesiologists rating, grade group, and prostate quantity, the danger of salvage therapy is decrease within the HIFU arm than with RP.
This outcome remained true when analyzing the subgroup with intermediate danger, stated EDAP.
“Importantly, at 12 months, the urinary continence was higher for the sufferers within the HIFU arm in comparison with surgical procedure,” Rhodes stated. “As effectively, sufferers within the HIFU arm have been again to a better baseline rating on erectile perform versus surgical procedure. It is very important word that the RP surgical procedure was usually achieved with robotics as effectively. It wasn’t completely all robotics, however numerous sufferers have been operated on utilizing robotic surgical procedure.”
The Worldwide Continence Society (ICS) rating, a measure of stress urinary incontinence deteriorated considerably much less for HIFU, at 29% versus RP at 44%, for all ages mixed. Worldwide Index of Erectile Operate-5 (IIEF-5), a validated measurement of erectile perform, decreased considerably much less after HIFU than after RP, for all ages included.
Publish-procedural advantages of HIFU on each erectile perform and urinary continence have been demonstrated regardless of sufferers within the HIFU-treated group being a mean of 9.6 years older.
“I feel actually what it factors to is that we now have a therapy possibility utilizing robotic focused HIFU remedy to depart the prostate gland in place, protect the organ, and solely go after the areas of most cancers inside that organ,” Rhodes stated.
EDAP has plans for Focal One
Focal One has already acquired regulatory clearance and is marketed within the U.S., Europe, Canada, Korea, Russia, and Brazil, amongst different nations. This newest examine expands entry to the system in France.
“[The study] is all about affected person entry,” Rhodes stated. “Sufferers want entry to new applied sciences that deal with the illness and enhance quality-of-life outcomes. So what I feel is most fun, the examine permits us to get in entrance of not solely sufferers themselves, however [also the] urologists who deal with these prostate most cancers sufferers, the hospitals that provide point-of-care providers, and even the payers that pay for therapy.”
Sooner or later, EDAP is excited by making use of Focal One’s expertise to different procedures, he stated. The corporate is at the moment working a Section 2 examine in Europe throughout three facilities to check Focal One’s effectiveness in treating benign prostatic hyperplasia (BPH).
“It’s a quite common illness in males as we age, and what we discover is, once we have been ablating prostate tissue for most cancers, males post-treatment improved of their urinary symptom scores,” Rhodes stated. “So that may logically make sense. If we’re ablating tissue and making a necrotic impact, then we’re changing the stress on the prostatic urethra.”
As well as, EDAP is exploring using Focal One to deal with deep infiltrating endometriosis.
“We’re speaking about endometrial implants which have evaded into the rectal wall,” defined Rhodes. “So, these create all types of issues, signs, and ache for ladies. We’ve developed, utilizing the identical Focal One platform, a method to ablate these endometrial implants underneath ultrasound steering.”
