Circularity Healthcare Announces Expansion with Global CRO of Series of Successful Pivotal Human Clinical Trials to Study Use of D’OXYVA® for Rapid, Economical and Noninvasive Home Treatment of Diabetic Foot Ulcers (DFU)

PASADENA, Calif., Feb. 1, 2021 5:31 AM PST (MORNINGSTAR)

Addressing urgent and increased DFU problem related to pandemic lockdowns.

Circularity Healthcare announced it had successfully executed a contract with the Professional Educational Research Institute (PERI) in 2020 to immediately begin a new clinical trial to study the use of D’OXYVA® to help prevent amputations and treat human diabetic foot ulcers at one-tenth the time and cost, and at least five times the efficacy of competing modalities.

A widely recognized global clinical research organization (CRO), PERI will specifically study at multiple sites at prestigious U.S. universities the use of D’OXYVA® to help address the recent epidemic of DFUs occurring in diabetic patients due to long-term pandemic quarantines and stay-at-home orders. Manufactured by Circularity, D’OXYVA® is a painless, noninvasive transdermal delivery system used in minutes to significantly improve blood perfusion, tissue oxygenation, and wound healing even where standard treatments have failed.

“D’OXYVA®‘s pivotal human clinical trial for complete healing of diabetic foot ulcers has been approved by the Western Institutional Review Board (WIRB), the largest in the world, and will include over a dozen high profile research sites at top U.S. universities and clinics,” said Senior Sales and Marketing Manager for Circularity, Jennifer Boadilla-Pelaez, RN. “Thousands of competing products in the past nearly twenty-five years have failed in achieving what D’OXYVA® has obtained in terms of regulatory approvals, clinical safety and efficacy in the past seven years. This is truly a game-changing milestone, not just for the company itself, but the entire medical community and the world and a preliminary report with meaningful results is expected within 6 months from starting the pivotal trial,” said Dr. Charles M. Zelen, PERI’s CEO.

DFUs are a major wound complication arising out of diabetes mellitus and occur in 3–13% of global diabetes patients, affecting millions of people. DFUs are caused by a variety of factors including decreased activity, diminished blood circulation, and people with underlying health conditions like diabetes are at higher risk for complications from COVID-19. Healthcare workers can expect to see far more instances of this persistent problem, especially with quarantine lockdowns, and it represents a significant health and economic risk to both patients and the overall healthcare system. Effective treatments that can reduce DFU recovery time, like D’OXYVA®, are absolutely crucial to combatting this newest wound epidemic.

What You Need to Know About Non-Healing Wounds

Chronic wounds are wounds that do not heal in a normal amount of time. This delay in healing can be due to a number of factors. Read on to learn about the case of a 63-year-old female patient with a large chronic wound on her lower, left extremity that was resistant to healing.

Lena was a 63-year-old, White female who had developed a large, non-healing wound on her lower, right leg. She could not remember what had caused the lesion other than having dropped a heavy mirror on her right shin several weeks earlier. Lena had a past medical history of high blood pressure, diabetes, heart failure, liver failure, and blood clots in her legs. She had been a cigarette smoker for the last 50 years.

Lena’s physical examination showed a large, deep, non-healing wound on her right shin. Surgical treatment and debridement, along with antibiotic treatment, had failed to result in significant treatment. After 8 weeks of adjunctive application with deoxyhemoglobin vasodilator D’OXYVA[1], the chronic wound improved without any further complications.

Main Reasons Chronic Wounds Do Not Heal

Chronic wounds normally do not heal for a number of reasons, including[2]:

  • Increased age of the patient leading to slower healing time
  • Decreased functioning of the immune system due to illnesses or chronic disease processes
  • Decreased circulation due to diabetes affecting the peripheral vascular system
  • Decreased circulation due to peripheral vascular disease
  • Peripheral neuropathy leading to loss of sensation and the inability to feel wound and ulcer formation
  • Insufficiency of the venous system leading to pooling of blood in the extremities and resultant poor perfusion
  • Poor nutrition leading to decreased ability to heal wounds normally
  • Impaired mobility leading to impaired limb perfusion
  • Increased general stress levels leading to decreased wound healing
  • Decreased general health causing general debilitation and loss of normal healing ability

Variations of Chronic Wounds

There are several different variations of chronic wounds, including pressure ulcers, arterial and venous ulcers, and diabetic ulcers.

Pressure ulcers[3], such as “bed sores,” occur when an area of the skin is under constant pressure, often when a patient is confined to a bed or wheelchair.

This causes the skin to break down in areas such as the coccyx, heel, ankles, and dorsum of the foot.

Arterial ulcers[4] form when there is a blockage in an artery causing reduction in blood flow to the lower extremities and subsequent reduction in the supply of oxygen to the affected area.

Venous ulcers[5] occur when the valves within veins become damaged leading to pooling of blood in the veins and reduced blow flow and oxygenation to the extremities.

Diabetic ulcers occur when high blood sugar levels cause damage to the nerves, especially in the lower extremities.

This leads to numbness, causing the patient to ignore cuts or ulcers until they enlarge, often becoming infected.

Diabetes also depresses the immune system, leading to slowed healing.

Treatments for Chronic Non-Healing Wounds

There are a number of treatments for non-healing wounds [7]. These include:

  • Antibiotics to treat bacterial infections
  • Antifungals to treat fungal infections
  • Hyperbaric oxygen treatments to improve chronic wound healing
  • Surgical debridement to remove necrotic tissue
  • Specialty wrapping of chronic wounds
  • Skin grafting to close chronic wounds
  • D’OXYVA[8]skin delivery deoxyhemoglobin vasodilator as a wound solution to improve blood flow and oxygenation to chronic wound areas

HOW D’OXYVA CAN HELP?

D’OXYVA® (deoxyhemoglobin vasodilator) provides advanced, painless, complete and fast wound care solution. It has demonstrated speeding up diabetic wound improvement to an average of 5 weeks**.

In addition, D’OXYVA  improved quality of life such as sleep, appetite and mood in just a week in 100% of subjects. No adverse events of any kind were reported during, and years after the studies.

Defects in Microcirculation and the Effect on Wound Healing: New Non-Invasive Treatments

The effects of defects in and poor functioning of the microcirculation on wound healing, especially in diabetic patients, can be devastating and life changing. As one particular example, Joseph L was a 63-year-old White male with a 24-year history of diabetes mellitus, hypertension, elevated cholesterol and arthritis. Joseph had been taking insulin for the past 12 years but his blood sugar levels were still poorly controlled.

On physical exam, Joseph had several very large, oozing and foul smelling deep ulcers located on the dorsum (top) of the left foot. After 8 weeks of intensive therapy utilizing the non-invasive D’OXYVA transdermal deoxyhemoglobin vasodilator, Joseph’s ulcers healed entirely and he avoided amputation of his left foot. Read on to learn more about this new non-invasive wound treatment that helps in wound healing.

 

What is the microcirculation?

The microcirculation refers to the smallest blood vessels in the body that supply oxygen to the tissues and remove waste products. This includes the arterioles, the venules and the capillaries. When the vessels of the microcirculation become damaged, it leads to decreased blood flow with lower oxygen blood levels and resultant damage to the skin resulting in a wound or ulcer.

Risk Factors for the Creation of Chronic Wounds

Patients with the following risk factors are at greater risk for non-healing wounds or ulcers (ulcers are the most common type of chronic wounds):

  • A history of decreased blood flow to a specific area (ischemia)

 

  • A history of uncontrolled diabetes (which leads to poor circulation, nerve damage and breakage of the skin)

 

  • A history of uncontrolled hypertension (high blood pressure)

 

  • A history of high cholesterol and atherosclerosis (cholesterol plaques in the arteries)

 

  • A history of blood clots (thrombosis)

 

Diabetic Foot Ulcers

Diabetic foot ulcers are a common complication of uncontrolled diabetes mellitus.1 Chronically elevated blood sugar levels damage the microcirculation of the lower extremities, which leads to ischemia and neuropathy (damage to the nerves). Diabetic patients often lose feeling in the feet and so are not aware of friction and pressure, which leads to breaks in the skin. This subsequently leads to open wounds that often do not heal over a 30 day period. These wounds can then become infected, leading to gangrene and eventual amputation.

 

An Example of a New Non-Invasive Treatment to Enhance Wound Healing

D’OXYVA is a non-invasive transdermal deoxyhemoglobin vasodilator that delivers FDA-approved ultra-purified CO2 molecules which diffuse through the skin leading to increased skin perfusion. In studies of the treatment of diabetic foot ulcers with D’OXYVA, increased diabetic wound healing was observed with wound closure often observed within 5 weeks.

 

Conclusion

Chronic conditions like uncontrolled diabetes and hypertension can cause damage to the microcirculation, which leads to delayed wound healing. New treatment methods like D’OXYVA deliver transdermal CO2-enhanced oxygen and nutrients to wound areas through the microcirculation. This speeds up wound healing and wound closure and helps avoid devastating complications such as amputations.
