About this study

Official title: Comparison of Resin Salve and Conventional Octenidine in Patients With Neuropathic Diabetic Foot Ulcers - a Prospective, Randomized and Controlled Clinical Trial

Prevalence of diabetic foot ulcers are reported to be 15% in patients who suffer from diabetes and ulcerations are present in 84% of all diabetes-related amputations. Peripheral neuropathy leading to unperceived trauma seems to be the major cause of diabetic foot ulcers with 45-60% of ulcers to be considered merely neuropathic and 45% of mixed, neuropathic and ischemic etiology. Ulceration of lower limb is one of the most common complications related with diabetes and one of the major causes for hospitalization of diabetic patients. The most significant contributors to diabetic lower limb ulceration are neuropathy, deformity, uncontrolled elevated plantar pressure, poor glycemic status, peripheral vascular disease, male gender and duration of diabetes. Treatment of lower limb ulcers imposes an enormous burden on health care resources worldwide, and at least 33% of all expenses are spent to treat diabetic ulcers manifested as a complication of diabetes.

Although at least 170 topical wound care products are available, evidence of the superiority of one over another is tenuous, well-designed randomized, controlled trials are rare, and the number of case-control or observational studies is limited. In recent years, salve prepared from Norway spruce (Picea abies) resin has successfully been used in medical context to treat both acute and chronic wounds and ulcers of various origins. The objective of this prospective, randomized and controlled clinical trial is to investigate healing rate and healing time of neuropathic diabetic foot ulcer in patients, who are suffering from infected fore- or mid-foot ulceration (PEDIS-classification ≥ Grade II; 19) originated from Type I or II diabetes, and in patients whose diabetic ulcerations are candidates for topical treatment with resin (Study treatment) or octenidine (Control treatment). In addition, factors contributing with delayed healing of ulceration, antimicrobial properties, safety and cost-effectiveness of the resin salve treatment and control treatment will be analyzed.

Read the detailed description

PRIMARY OBJECTIVES

Primary objectives are:

  • to scrutinize complete healing of neuropathic diabetic foot ulceration over time.
  • to analyze successful eradication rate of pathogenic bacteria from the ulcers within the study period as documented by negative swab culture.
  • to analyze the rate of ulcers with 50% decrease in ulcer size and disappearing of clinical signs of infection over time.

SECONDARY OBJECTIVES

Secondary objectives are:

  • to assess potential contributors to delayed ulcer healing.
  • to study the safety and compliance related with the treatment methods.
  • to estimate the overall costs of the ulcer treatment with the resin salve treatment or octenidine treatment.

INCLUSION AND EXCLUSION CRITERIA

Inclusion criteria are:

  • an adult patient (18-80 years) with infected neuropathic foot ulceration due to type I or II diabetes.
  • PEDIS-classification ≥ Grade II.

Exclusion criteria are:

  • a patient whose life expectancy is less than 6 months.
  • an ulceration of ischemic or neuroischemic origin.
  • presence of systemic inflammatory response signs.
  • heel ulceration.
  • presence of osteomyelitis.
  • pregnancy.
  • known hypersensitivity to any of the ingredient including in the study or control treatment products. - a patient who is unable to give informed consent.
  • a patient who has an advanced malignant disease.

METHODS Patient selection Altogether 40 adult patients (18 - 80 years) suffering from infected neuropathic fore- or mid-foot ulceration originated from type I or II diabetes (PEDIS-classification ≥ Grade II) are randomly allocated into two groups (n = 20 patients / group) to receive either topical resin salve treatment or topical octenidine treatment for an appropriate diabetic ulceration. The patients who are recruited to the current study, are selected by the physicians, who are specialized in the treatment of diabetes and its complications. Treatment is commenced and followed-up at the outpatient clinic of the Diabetic Foot Clinic Regional Diabetic Centre, Department of Hypertension and Diabetology, Gdansk, Poland. Informed consent will be obtained from all patients.

FOLLOW-UP Demographics, clinically relevant medical, and follow-up data is gathered on the Clinical Report Form (CRF) by the responsible physicians for every patient at the beginning of the study, and within the every visit at the Diabetic Foot Clinic of the Regional Diabetic Centre until the study ends at six months later, at last. Thus, all recruited patients visit at the Diabetic Foot Clinic: 1. in the beginning of the study, and at 1, 2, 3, and 4 week time-points thereafter. After that, consecutive visit for every 3 to 4 weeks are arranged until the ends after the 6 months from the initiation. If the patient's clinical situation requires more frequent visits at the Diabetic Foot Clinic, those are arranged on the basis of the decision of research physician.

If the ulcer healing takes less than 6 months, the last follow-up information on the CRF is filled when the ulcer is considered being fully healed (primary objective is achieved). If the ulcer is not fully healed in 6 months, the treatment is considered unsuccessful, and follow-up is discontinued (primary objective is not achieved). Photographs are taken within every control visit at the outpatient department. Any notable improvement, deterioration, or any factor that might contribute with the ulcer healing during the follow-up, e.g. mechanical / surgical ulcer revision, cleansing, or antibiotic treatment will be registered on the CRF: Thus, CRF includes the details of:

  • size of the ulcer [width (mm) x length (mm) x depth (mm)].
  • signs of infection.
  • swab culture.
  • plain x-ray.
  • erythrocyte sedimentation rate (ESR).
  • C-reactive protein (CRP).
  • full blood count.
  • photographs with an appropriate measure.
  • use of antibiotics.
  • rate of dressing changes.
  • potential side-effects (i.e. signs of hypersensitivity or allergic reaction).
  • the use of off-loading shoe, and any specific notes or observations during the treatment period.

SAFETY ISSUES Hypersensitivity or allergy for resin or control treatment is taken into account, and if any symptoms of allergic reactions i.e. contact dermatitis appear, the study is discontinued for this particular patient.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Resin salve treatmentDevice

    Also called Abilar 10% Resin Salve

    Resin is collected in the municipality of Kolari, Finland, from the trunks of full-grown Norway spruce (Picea acies) trees. Bark and other impurities are removed mechanically. The resin is then liquefied and purified by filtering. Resin salve is composed of a 10% (w/w) mixture of purified spruce resin in a standardized salve base. None of the components of the salve base have antibacterial properties. Resin salve is produced from the pure resin to the final product in accordance with the Good Manufacturing Standards (GMP) and it holds the European CE mark (Abilar 10% Resin Salve, Repolar Ltd., Espoo, Finland, CE 0537).

  • Octenidine treatmentDevice

    Also called Octenisept

    Octenidine dihydrochloride is a cationic surfactant and bis-(dihydropyridinyl)-decane derivative, used in concentrations of 0.1-2.0%. It is similar in its action to the quaternary ammonium compounds, but is of somewhat broader spectrum of activity. Octenidine is currently increasingly used in continental Europe as a substitute for quats or chlorhexidine (with respect to its slow action and concerns about the carcinogenic impurity 4-chloroaniline) in water- or alcohol-based skin, mucosa and wound antiseptics. In aqueous formulations, it is often potentiated with addition of 2-phenoxyethanol.

Study groups in NCT02169167
Study groupRoleWhat they receive
Resin salve treatmentExperimentalThe resin salve may be spread directly onto the diabetic ulcer, after which the area is covered with a bandage suitable for local wound care. The bandage prohibits salve from moving away from the ulcer area. If the skin condition is more widespread or contains cavities or fistulae, the salve may be spread as a film with a thickness of at least 1 mm onto a gauze or gauze ribbon that is then used to fill the cavity or fistulae channel. Bandages are changed every 1-3 days, depending on the degree of infection and amount of ulcer secretion.
Receives: Device: Resin salve treatment
Octenidine treatmentActive comparatorOctenidine treatment is implemented with the similar manner as resin salve treatment by using sterile gauze that is impregnated with the octenidine dihydrochloride.
Receives: Device: Octenidine treatment
