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 targeted ultrasound, or HIFU, remedy of localized prostate most cancers. The examine in contrast the French firm’s robotic Focal One system towards radical prostatectomy, or RP, surgical procedure as the primary line of remedy.
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 remedy strategies match up with the gold star commonplace of surgical procedure, mentioned EDAP. The corporate claimed that the robotic remedy can enhance quality-of-life outcomes for these scuffling with prostate most cancers.
These quality-of-life adjustments, like a lowered fee of urinary incontinence or lack of erectile operate, 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 mentioned, 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.
“Understanding that, even within the fingers of robots and doing nice surgical procedure, there was all the time the chance of uncomfortable side effects, as a result of the surgical procedure remains to be surgical procedure, whether or not it’s accomplished with a robotic or not,” he informed The Robotic Report. “What we noticed was that males undergo from lack of sexual operate, lack of urinary management, and even in some situations, and we don’t all the time get the most cancers out.”
“Round 2015, there was quite a lot of dialogue about overtreating prostate illness with radical surgical procedure, regardless of the chance of uncomfortable side effects, Rhodes added. “Now, we are able to higher risk-stratify sufferers, and there are different choices moreover radical surgical procedure, resembling Focal One, which makes use of advances in imaging and might import biopsy knowledge for the surgeon to arrange a goal plan for guided precision ablation.”

Focal One offers a non-surgical various
Focal One mentioned its HIFU Robotic System makes use of high-performance imaging and HIFU know-how to permit urologists to focus on the prostate with submillimeter accuracy. This permits them to spare wholesome, surrounding tissue and protect the affected person’s high quality of life, the corporate mentioned.
Rhodes emphasised that even when surgeons use robots, surgical procedure remains to be surgical procedure. “Reducing, coagulating, suturing, ranking traction, and harm — all these items occur throughout surgical procedure,” he mentioned. “In our [non-invasive] strategy, there is no such thing as a surgical procedure, no blood loss, no chopping, no radiation.”
As a result of Focal One doesn’t require a doctor to carry out surgical procedure, it may well 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 mentioned. This could significantly cut back staffing calls for that many hospitals are already scuffling with.
“That advantages everyone, and positively urologists admire that profit,” mentioned Rhodes. “As a result of there’s no surgical procedure concerned, there’s no surgical fatigue.”
“Physicians can work with imaging they’re conversant in, utilizing the identical ultrasound know-how they used to carry out a biopsy on the affected person,” he added. “In lots of instances, they had 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 typically 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 remedy facilities. 1,967 consecutive sufferers had 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 had been adopted for 30 months. The outcomes had been printed within the journal European Urology.
At 30 months, the adjusted salvage treatment-free survival (STFS) was increased 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 chance of salvage remedy is decrease within the HIFU arm than with RP.
This consequence remained true when analyzing the subgroup with intermediate danger, mentioned EDAP.
“Importantly, at 12 months, the urinary continence was higher for the sufferers within the HIFU arm in comparison with surgical procedure,” Rhodes mentioned. “As nicely, sufferers within the HIFU arm had been again to the next baseline rating on erectile operate versus surgical procedure. It is very important be aware that the RP surgical procedure was typically accomplished with robotics as nicely. It wasn’t solely all robotics, however a lot of sufferers had 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 operate, decreased considerably much less after HIFU than after RP, for all ages included.
Submit-procedural advantages of HIFU on each erectile operate and urinary continence had been demonstrated regardless of sufferers within the HIFU-treated group being a median of 9.6 years older.
“I believe actually what it factors to is that we now have a remedy choice 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 mentioned.
EDAP has plans for Focal One
Focal One has already obtained regulatory clearance and is marketed within the U.S., Europe, Canada, Korea, Russia, and Brazil, amongst different international locations. This newest examine expands entry to the system in France.
“[The study] is all about affected person entry,” Rhodes mentioned. “Sufferers want entry to new applied sciences that deal with the illness and enhance quality-of-life outcomes. So what I believe 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 remedy.”
Sooner or later, EDAP is all for making use of Focal One’s know-how to different procedures, he mentioned. The corporate is at present 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 had been ablating prostate tissue for most cancers, males post-treatment improved of their urinary symptom scores,” Rhodes mentioned. “So that will logically make sense. If we’re ablating tissue and making a necrotic impact, then we’re changing the strain 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 every kind of issues, signs, and ache for ladies. We’ve developed, utilizing the identical Focal One platform, a technique to ablate these endometrial implants below ultrasound steerage.”
