FDA APPROVES LIMFLOW SYSTEM IN PATIENTS WITH CHRONIC LIMB-THREATENING ISCHEMIA AND NO SUITABLE ENDOVASCULAR OR SURGICAL REVASCULARIZATION OPTIONS

New Therapeutic Option Has Potential to Reduce Rate of Major Limb Amputation in U.S.

PARIS AND SAN JOSE, CALIF. – 09/12/2023 — LimFlow SA, a pioneer in the development of minimally-invasive technology for the treatment of chronic limb-threatening ischemia (CLTI), a severe form of peripheral artery disease (PAD), announced today that the U.S. Food and Drug Administration (FDA) has approved the LimFlow System to help people with CLTI who have no other suitable endovascular or surgical treatment options and are facing major amputation.

The LimFlow System for Transcatheter Arterialization of Deep Veins (TADV) is designed to reestablish blood flow in deep veins for “no-option” CLTI patients. The therapy is designed to save patients’ legs from major amputation, as limb loss is associated with significant complications, mortality, and deterioration of quality of life. CLTI affects up to four million Americans1 and disproportionately impacts minority and underserved patients,2 resulting in more than 150,000 major amputations per year in the U.S.3 FDA approval of the LimFlow System will enable these patients to have access to a minimally invasive treatment giving them a chance to save their limbs and improve their quality of life.

“With LimFlow, we now have an option for the sickest patients who were previously consigned to limb loss and the downward spiral that accompanies it,” said Daniel Clair, MD, PROMISE II/III Co-Principal Investigator, Professor and Chair of the Department of Vascular Surgery at Vanderbilt University Medical Center Section of Surgical Sciences. “Using this new treatment, we have seen many patients whose limbs have been saved, whose pain has been reduced or resolved, whose chronic wounds are healed or healing, and who can now look forward to happier and more active lives.”

FDA approval was based on successful outcomes seen in the PROMISE II pivotal trial, recently published in The New England Journal of Medicine, and from positive clinical results seen in earlier studies. In the PROMISE II study, 76% of no-option CLTI patients were able to keep their leg and experienced progressive wound healing, with many having significant pain relief during the time following LimFlow treatment.4

The LimFlow System is the first and only FDA-approved device for TADV and previously received Breakthrough Device Designation from the FDA.

“At LimFlow, our vision is to achieve great outcomes for patients suffering from CLTI. We developed a novel way to make a vein function as an artery with the goal of saving limbs, and by doing that, saving patients’ lives,” said LimFlow CEO Dan Rose. “We thank the FDA for their collaborative review process and we look forward to introducing and expanding use of the LimFlow System in the U.S.”

The LimFlow System is indicated for patients who have chronic limb-threatening ischemia (CLTI) with no suitable endovascular or surgical revascularization options and are at risk of major amputation.

The LimFlow System received the CE Mark and is currently available commercially in Europe. The LimFlow System has not been approved for sale in Canada or Japan.

About Chronic Limb-Threatening Ischemia (CLTI)

CLTI is the most severe form of PAD and often occurs in patients suffering from diabetes, coronary artery disease, obesity, high cholesterol, and/or high blood pressure. Patients with CLTI often experience profound, chronic pain and develop festering wounds or infections that lead to major limb amputation, an event closely associated with increased mortality and reduced quality of life. To relieve the symptoms of CLTI, patients today are treated primarily with angioplasty or open bypass surgery. In many late-stage patients, however, neither option is feasible due to extensive disease in the target arteries or other anatomical constraints.

About LimFlow and the LimFlow System

When all other therapeutic options have been exhausted and a CLTI patient is facing major amputation, the minimally invasive LimFlow System for Transcatheter Arterialization of Deep Veins (TADV) bypasses permanently blocked arteries in the leg and foot and delivers oxygenated blood back into the foot via the veins. Restoring perfusion in the lower limbs may help resolve chronic pain, improve quality of life, enable wound healing, and prevent major amputation.

LANDMARK NEW ENGLAND JOURNAL OF MEDICINE PUBLICATION REPORTS POSITIVE RESULTS FROM PROMISE II PIVOTAL TRIAL SHOWING THAT LIMFLOW SYSTEM SAVES MOST PATIENTS WITH END-STAGE PERIPHERAL ARTERY DISEASE FROM MAJOR AMPUTATION

  • PROMISE II Trial Met Primary Endpoint
  • Therapy Demonstrates 76% Limb Salvage in Patients with Chronic Limb-Threatening Ischemia Who Otherwise Faced Amputation

PARIS – March 30, 2023 — LimFlow SA, a pioneer in the development of minimally-invasive technology for the treatment of chronic limb-threatening ischemia (CLTI), a severe form of peripheral artery disease (PAD), announced today that results from the PROMISE II U.S. pivotal trial were published in today’s issue of the New England Journal of Medicine (NEJM). The results demonstrated that the LimFlow System achieved 66% amputation-free survival (patients were alive and amputation-free) at six months. This exceeded the FDA’s Performance Goal with statistical significance.

The LimFlow System for TADV (Transcatheter Arterialization of Deep Veins) is designed to reestablish blood flow in deep veins for “no-option” CLTI patients who have exhausted all other treatment methods and face major amputation of their lower limb. The therapy is designed to prevent amputation, which is associated with significant complications, mortality, and deterioration of quality of life. CLTI affects up to four million Americans and disproportionately impacts minority and underserved patients, resulting in more than 150,000 major amputations per year in the U.S.

“The publication of PROMISE II in the New England Journal of Medicine reinforces the transformational value of TADV for a patient population in great need,” stated Mehdi Shishehbor, DO, MPH, PhD, PROMISE II Co-Principal Investigator, President of the Harrington Heart and Vascular Institute, University Hospitals, and lead author of the NEJM paper. “The introduction of this therapy provides the possibility of limb salvage for a no-option CLTI population previously consigned to primary amputation, potentially reducing the suffering, mortality, and economic burden in this ever-growing segment of patients.” “These results establish TADV as a real alternative to major amputation for patients facing inevitable limb loss from no-option CLTI,” said Daniel Clair, MD, PROMISE II Co-Principal Investigator, Professor and Chair of the Department of Vascular Surgery at Vanderbilt University Medical Center Section of Surgical Sciences. “This therapy will enable us to redefine the concept of a ‘no-option’ CLTI patient by giving us a treatment that offers patients limb salvage and hope.”

The PROMISE II Trial also demonstrated:

  • 76% limb salvage rate, where more than three-quarters of patients kept their leg and avoided amputation
  • 76% of patients had wounds that were completely healed (25%) or in the process of healing (51%)
  • Patient pain was substantially reduced, with average pain scores dropping from 5.3/10 prior to treatment to 3.0/10 six months after treatment
  • 99% technical success of the procedure, indicating a reproducible procedure across diverse sites and investigators

PROMISE II is a landmark trial of the most severe CLTI patient group ever studied in a vascular device pivotal trial, with 100% of patients suffering from end-stage peripheral artery disease (classified as Rutherford Stage 5 or 6), 77% with diabetes, and 57% with chronic kidney disease, many of whom were on dialysis. The multi-center, prospective, single-arm study encompassed 105 no-option CLTI patients treated at 20 U.S. sites. PROMISE II was designed to be representative of a broad patient population, with 43% of subjects being Black, Hispanic, or Latino, and 31% female. Subjects will be followed out to three years. The no-option patients treated in PROMISE II were determined by an independent physician committee to be no longer eligible for conventional endovascular or surgical therapy to treat their CLTI.

“Too often, patients are confronted with the limits of traditional interventional options and must undergo a major amputation, which often leads to severe complications, greatly reduced quality of life, and an early death. The LimFlow System demonstrated remarkable success in relieving patients’ pain and healing their wounds, diverting them from amputation and putting them on a path towards a better life,” said LimFlow CEO Dan Rose. “We want to thank the clinical investigators and their research teams for their commitment to this important research. As this is a large and growing patient population in great need of a new therapeutic option, we look forward to engaging further with the FDA as we seek regulatory approval.”

LIMFLOW RAISES $40 MILLION (€36 MILLION) IN SERIES D FINANCING

Funds to Support Completion of Clinical Program Through Commercialization of Novel Device Designed to Prevent Amputations in Patients with Chronic Limb-Threatening Ischemia

PARIS–(BUSINESS WIRE)–LimFlow SA, a pioneer in the development of minimally-invasive technology for the treatment of chronic limb-threatening ischemia (CLTI), a severe form of peripheral artery disease (PAD), today announced it has closed a $40 million (€36 million) oversubscribed Series D financing round. New investors Longitude Capital, Soleus Capital Management and an undisclosed strategic investor joined the round along with current major shareholders of the company: Sofinnova Partners, through its Crossover Strategy fund; Bpifrance, the French sovereign investment bank; and Balestier, a Singaporean family fund.

The LimFlow System, designated by the FDA as a Breakthrough Technology, uses a minimally-invasive family of transcatheter products designed to optimize perfusion of the critically ischemic foot, potentially avoiding major amputation, resolving pain and promoting wound healing. Proceeds from the Series D financing will fund follow-up for the PROMISE II U.S. pivotal trial necessary to obtain FDA approval and will support the commercialization of the LimFlow System for deep vein arterialization.

The company recently completed enrollment in PROMISE II, the U.S. pivotal trial of the LimFlow System. It also completed enrollment in CLariTI, a natural history study of high-risk and no-option CLTI patients, intended to shed light on outcomes from patients treated with the current standard of care. Over the last year, the company also integrated the second-generation of its LimFlow System into its clinical program, and reported positive two-year data from its PROMISE I U.S. feasibility study.

“We are thankful for the support of so many industry-leading investors, both new and existing, who recognize the potential of the LimFlow System to address a major clinical need in saving patients from amputation,” said LimFlow CEO Dan Rose. “We look forward to sharing results from our pivotal trial later this year, and to the prospect of being able to make the LimFlow system commercially available as early as next year to the patients in the U.S. and Europe who desperately need it.”

“We are truly impressed by the clinical results LimFlow has delivered for patients who have exhausted all other treatment options. We are excited about the technology’s potential to transform the way CLTI patients are treated, and in turn, transform the quality of their lives,” said Maxwell Bikoff, Principal at Longitude Capital.

“The LimFlow management team has achieved key milestones and Series D financing needed to successfully bring the LimFlow System to market. We are enthusiastic about continuing to work with the company to help make this game-changing technology accessible to patients in the near future,” said Kinam Hong, MD, Partner at Sofinnova Partners.

US PIVOTAL STUDY AND CLARITI COMPLETE ENROLLMENT

LimFlow Completes Enrollment in PROMISE II U.S. Pivotal Trial of Breakthrough Device Designed to Prevent Amputations in No-Option Patients with Chronic Limb-Threatening Ischemia

PARIS- March 15, 2022 — LimFlow SA, a pioneer in the development of minimally-invasive technology for the treatment of chronic limb-threatening ischemia (CLTI), a severe form of peripheral artery disease (PAD), announced today that it has completed patient enrollment in the PROMISE II pivotal trial of the LimFlow System. The LimFlow System is designed to reestablish arterialization in deep veins for patients who have exhausted other methods and  face major amputation of their lower limbs.

PROMISE II is a multi-center, prospective, single-arm study being conducted at multiple sites in the U.S. Using an adaptive statistical design, the study enrolled 105 no-option CLTI patients. Endpoints include amputation-free survival at six months, limb salvage and wound healing, and subjects will be followed out to three years. The no-option patients treated in PROMISE II were determined by an independent physician committee to be no longer eligible for conventional endovascular or surgical therapy to treat CLTI.

“The PROMISE II investigators are very encouraged by our experience using the LimFlow System to treat CLTI patients with no other options. These are likely the sickest patients ever to have been enrolled in a limb salvage trial,” said Daniel Clair, MD, PROMISE II principal investigator and Professor and Chair of the Department of Vascular Surgery at Vanderbilt University Medical Center Section of Surgical Sciences. “Major amputations have a devastating effect on the lives of patients and their families. We are excited about the prospect of helping improve the lives of more of these patients once this novel technology becomes broadly available.”

LimFlow also announced completion of enrollment in the CLariTI study of approximately 200 high-risk and no-option CLTI patients. The prospective, observational, multicenter CLariTI study will track the clinical progression of CLTI and incidence of death, amputation, and revascularization attempts in patients undergoing standard medical management for the disease over a one-year period.

“Despite suffering from the most advanced form of CLTI, these no-option and high risk patients have been excluded from other trials,” said Anahita Dua, MD, MS, MBA, FACS, CLariTI principal investigator, vascular surgeon at Massachusetts General Hospital, and Assistant Professor of Surgery at Harvard Medical School. “Our hope is that the CLariTI study gives us better insights into the reintervention, amputation and death rates in no-option and high-risk patients treated with the current standard of care.”

“It is tremendous to see the clinical community’s enthusiasm for the PROMISE II pivotal trial and the prospect of a new option for these desperate patients,” said LimFlow CEO Dan Rose. “While PROMISE II will demonstrate the progress of patients treated with LimFlow, CLariTI will tell us more about outcomes for high risk and no-option patients being treated with today’s interventional options. Running these studies concurrently gives us a wealth of data in order to learn about the progress of disease and quality of life in both treated and untreated patients. It will also highlight the gap between what is achievable with today’s FDA-approved therapies and what is possible with our transformational approach to CLTI using the LimFlow System.”

LATE-BREAKING DATA FROM PROMISE I STUDY ON LIMFLOW SYSTEM CONFIRM EXCELLENT SUSTAINED OUTCOMES IN PATIENTS WITH NO-OPTION CHRONIC LIMB-THREATENING ISCHEMIA

Limb salvage in 77 percent of patients at 2 years with “no-option” for revascularization via traditional techniques

24-Month Results Presented Wednesday at VIVA 2021 Conference

SAN JOSE, Calif. and LAS VEGAS – LimFlow SA, the pioneer in the development of minimally-invasive technology for the treatment of chronic limb-threatening ischemia (CLTI), a severe form of peripheral artery disease (PAD), on Wednesday announced 24-month results from the PROMISE I Study of the LimFlow Percutaneous Deep Vein Arterialization System (“LimFlow System”), confirming excellent and sustained outcomes for both amputation-free survival and wound healing. The late-breaking data was presented on Wednesday at the Vascular Interventional Advances (VIVA) Conference in Las Vegas, Nevada.

“The presentation of the PROMISE I 24-month results validate the benefits of the LimFlow System,” said Daniel Clair, MD, PROMISE I principal investigator, Professor and Chair of the Department of Vascular Surgery at Vanderbilt University Medical Center Section of Surgical Sciences. “The high percentage of no-option CLTI patients that remained amputation free at 24-months is a major positive step forward for a condition characterized by high amputation and mortality rates.”

PROMISE I is a multi-center, prospective, single-arm study of the LimFlow System, conducted at seven study centers across the U.S. All of the 32 patients enrolled in the study had non-healing wounds on the target foot. The primary endpoints were freedom from amputation (FFA), amputation-free survival (AFS), and survival overall. There were no amputations after day 75 in the study.  At 24-months, FFA remained at 77 percent with an AFS of 59 percent. Three additional deaths within the second year of study resulted in 77 percent survival (two non-limb-related deaths; one from sepsis due to a non-healing wound in the non-treated foot). 92 percent had all wounds classified as healed or healing as adjudicated by an independent core lab. Technical success was reported at 97 percent.

“The 2-Year data from PROMISE I US feasibility study is highly encouraging and sends a strong signal about the potential of the LimFlow System to strengthen our mission of no limb left behind,” said LimFlow CEO Dan Rose. “We are swiftly advancing our study of the LimFlow System in the ongoing PROMISE II US pivotal study in a patient population which is facing a very poor overall prognosis in terms of mortality and quality of life after major limb amputation. The LimFlow System is designed to help heal wounds and avoid major limb amputation, and we are proud of our mission of ‘No Limb Left Behind.'”

The late-breaking data was presented on Wednesday at the Vascular Interventional Advances (VIVA) Conference in Las Vegas, Nevada.

“The presentation of the PROMISE I 24-month results validate the benefits of the LimFlow System,” said Daniel Clair, MD, PROMISE I principal investigator, Professor and Chair of the Department of Vascular Surgery at Vanderbilt University Medical Center Section of Surgical Sciences. “The high percentage of no-option CLTI patients that remained amputation free at 24-months is a major positive step forward for a condition characterized by high amputation and mortality rates.”

PROMISE I is a multi-center, prospective, single-arm study of the LimFlow System, conducted at seven study centers across the U.S. All of the 32 patients enrolled in the study had non-healing wounds on the target foot. The primary endpoints were freedom from amputation (FFA), amputation-free survival (AFS), and survival overall. There were no amputations after day 75 in the study.  At 24-months, FFA remained at 77 percent with an AFS of 59 percent. Three additional deaths within the second year of study resulted in 77 percent survival (two non-limb-related deaths; one from sepsis due to a non-healing wound in the non-treated foot). 92 percent had all wounds classified as healed or healing as adjudicated by an independent core lab. Technical success was reported at 97 percent.

“The 2-Year data from PROMISE I US feasibility study is highly encouraging and sends a strong signal about the potential of the LimFlow System to strengthen our mission of no limb left behind,” said LimFlow CEO Dan Rose. “We are swiftly advancing our study of the LimFlow System in the ongoing PROMISE II US pivotal study in a patient population which is facing a very poor overall prognosis in terms of mortality and quality of life after major limb amputation. The LimFlow System is designed to help heal wounds and avoid major limb amputation, and we are proud of our mission of ‘No Limb Left Behind.'”

About Chronic Limb-Threatening Ischemia (CLTI)

CLTI is the most severe form of PAD and often occurs in patients suffering from coronary artery disease, diabetes, obesity, high cholesterol, and/or high blood pressure. Patients with CLTI often experience profound, chronic pain and develop festering wounds or infections that lead to major limb amputation, an event closely associated with increased mortality and reduced quality of life. To relieve the symptoms of CLTI, patients today are treated primarily with angioplasty or open bypass surgery. In many late-stage patients, however, neither option is feasible due to extensive disease in the target arteries or other anatomical constraints.

No-option CLTI is defined as being ineligible for surgical or endovascular arterial revascularization as adjudicated by an independent committee of vascular surgeons

THE LIMFLOW SYSTEM FOUND TO BE COST-EFFECTIVE, ACCORDING TO THE NEWEST STUDY PUBLISHED IN THE JOURNAL OF CRITICAL LIMB ISCHEMIA

Percutaneous Deep Vein Arterialization (pDVA) with the LimFlow System offers a cost-effective and high-value alternative to traditional therapies or amputation in a new study, published July 2021

PARIS – July 28th,  2021 — Today, LimFlow SA, the pioneer in developing minimally-invasive technology to treat chronic limb-threatening ischemia (CLTI), announced remarkable health economic findings for pDVA in the latest study, published July 26th, 2021, ​in the Journal of Critical Limb Ischemia.


“The cost-effectiveness analysis builds on recently published 12-month data from the PROMISE I study by showing that pDVA with the LimFlow System can be a high-value therapy alternative to the status quo for no-option CLTI patients,” stated Peter A. Schneider, MD., Professor of Surgery at the University of California, San Francisco, and co-author of the published article. “This research highlights the health economic benefits of reducing amputations and the need to offer patients a better alternative worldwide.”

“CLTI currently affects up to 3.8 million people in the United States and costs the health care system $200-300 billion in all-cause costs annually”, said Mary Yost, President, The Sage Group. “More alarming than the costs and prevalence of CLTI is the mortality rate; more patients die within five years of a CLTI diagnosis than with any type of cancer except for lung cancer.”

In partnership with experts from the University of California San Francisco, Massachusetts General Hospital/Harvard Medical School, and Wing Tech Inc, the research found significant and promising data from their cost-effectiveness analysis comparing pDVA with the LimFlow System to the status quo treatment for no-option CLTI patients. The status quo was defined by a meta-analysis conducted by the Yale Cardiovascular Research Group on no-option patient outcomes from other reputable studies ranging from 2006 to 2018, which is pending publication in the Journal of Critical Limb Ischemia. The comparative analysis demonstrates that expected outcome improvements with pDVA entirely justify its incremental costs and qualifies it as a “high value” therapy per established willingness-to-pay thresholds. This important publication further utilized rigorous health-economic methodologies to expose the technology’s ability to positively impact the lives of patients who are currently underserved and that LimFlow can do so without overburdening the healthcare system.

“Avoiding major amputation is a key treatment goal in CLTI due to its associated high costs, loss of functional status and quality of life, and high mortality,” explained Dan Rose, CEO, LimFlow SA. “The analysis using data from PROMISE I demonstrates our technology can provide significant clinical and health-economic value to patients and healthcare providers who are drastically underserved by the status quo.”

PUBLICATION OF ONE YEAR OUTCOMES FROM PROMISE I U.S. STUDY OF THE LIMFLOW SYSTEM DEMONSTRATES EXCELLENT SUSTAINED AMPUTATION-FREE SURVIVAL AND WOUND HEALING IN PATIENTS WITH NO-OPTION CHRONIC LIMB-THREATENING ISCHEMIA

Twelve-Month Results Published in the Journal of Vascular Surgery

Paris, May 20, 2021 — LimFlow SA, the pioneer in the development of minimally-invasive technology for the treatment of chronic limb-threatening ischemia (CLTI), a severe form of peripheral artery disease (PAD), today announced the publication of 12-month data from the full patient cohort in its PROMISE I study of the LimFlow Percutaneous Deep Vein Arterialization System in the Journal of Vascular Surgery. Results showed sustained positive outcomes for both amputation-free survival and wound healing. The minimally-invasive LimFlow System is designed to bypass blocked arteries in the leg and deliver oxygenated blood back into the foot via the veins in CLTI patients who are facing major amputation and have exhausted all other therapeutic options.

PROMISE I is a multi-center, prospective, single-arm study of the LimFlow System conducted at seven U.S. centers and enrolled 32 end-stage – or “no option” – CLTI patients, 100 percent of whom had non-healing wounds on the target foot, 69 percent of whom had diabetes and 34 percent of whom had renal insufficiency. No-option CLTI is defined as being ineligible for surgical or endovascular arterial revascularization as adjudicated by an independent committee of vascular surgeons.

“The publication of the PROMISE I results in the Journal of Vascular Surgery further validates the benefits of the LimFlow System,” said Daniel Clair, MD, PROMISE I principal investigator, and chair of the department of surgery at the University of South Carolina (USC) and Prisma Health-USC Medical Group. “The LimFlow pDVA system was effective in treating no-option CLTI resulting in a high percentage of treated patients healing their wounds and surviving free of major amputation at 12 months.”

In the PROMISE I study, 70 percent of patients achieved amputation-free survival at 12 months following treatment with the LimFlow System, and 75 percent had all wounds classified as healed or healing at 12 months as adjudicated by an independent core lab. Technical success was reported at 97 percent.

“Given the unacceptable rates of major amputations globally we are encouraged by the publication of the 12 month PROMISE I data in the prestigious Journal of Vascular Surgery,” said LimFlow CEO Dan Rose. “We are making great strides in our currently enrolling PROMISE II pivotal trial in the US and Japan, and we look forward to advancing our mission of leaving no limb left behind.”

LIMFLOW RECEIVES JAPAN PMDA APPROVAL FOR CLINICAL STUDY OF MINIMALLY-INVASIVE TECHNOLOGY DESIGNED TO PREVENT AMPUTATIONS IN CHRONIC LIMB-THREATENING ISCHEMIA PATIENTS

PARIS – March 23, 2020 — LimFlow SA, a pioneer in the development of minimally-invasive technology for the treatment of chronic limb-threatening ischemia (CLTI), a severe form of peripheral artery disease (PAD), announced today that the Japanese Pharmaceuticals and Medical Devices Agency (PMDA) has approved its Clinical Trial Notification (CTN) for the Japanese cohort of the ongoing PROMISE II pivotal trial of the LimFlow Percutaneous Deep Vein Arterialization (pDVA) System. 

PROMISE II is a multi-center, prospective, single-arm study being conducted in the U.S. and Japan as part of the Medical Device Harmonization by Doing (HBD) regulatory collaboration between the two countries. Using an adaptive statistical design, the study plans to enroll 60 to 120 “no option” CLTI patients at 25 sites, four of which will be in Japan. The primary endpoint is amputation-free survival at six months; additional endpoints include limb salvage and wound healing. Subjects will be followed out to three years. The “no option” patients who are candidates for the PROMISE II study are no longer eligible for conventional endovascular or surgical therapy for CLTI, as determined by an independent physician committee.

“Late-stage CLTI patients have a terrible quality of life, where they live with pain and limited mobility. Treatment success with these patients is defined by wound healing and amputation-free survival. The investigational LimFlow therapy has the potential to achieve both – by restoring oxygen-rich blood flow to the ischemic foot, it may create the conditions for chronic wounds to heal, which may enable patients to avoid amputation and keep their limb,” said Hiroyoshi Yokoi, MD, PROMISE II Japanese Principal Investigator and Director, Cardiovascular Center, Fukuoka Sanno Hospital. “We recently received Investigational Review Board approval to begin the PROMISE II trial at Fukuoka Sanno Hospital and I am enthusiastic about being able to offer a promising new option to my no-option patients.”

Nobuyoshi Azuma, MD, Professor of Vascular Surgery at Asahikawa Medical University and a PROMISE II investigator said, “In Japan’s aging society, arteriosclerosis of the lower limbs is increasing, and severe lower limb ischemia encompassing foot pain, ulceration and necrosis due to impaired blood flow associated with diabetes and dialysis is becoming a major problem. We hope that pDVA with the LimFlow System will be a viable option and we look forward to starting the trial in Japan soon.”

“We are excited about the momentum that adding several Japanese centers will bring to patient enrollment in our important PROMISE II trial,” said LimFlow CEO Dan Rose.

“Participating in the HBD program allows us to leverage the clinical data from all patients enrolled in the U.S. and Japan towards Shonin approval in Japan. It also complements our acceptance in the FDA’s Breakthrough Device program, which is expected to accelerate our regulatory and reimbursement pathways. This is another promising step in our mission to bring our groundbreaking technology to CLTI patients who need it as soon as possible, wherever they may be in the world.”
