Study summary

The purpose of this study is to estimate efficiency, tolerance, safety of "Foscelantan, medicinal plate 4.0x5.0 cm in package No. 1" among adult patients who have purulent-inflammatory processes of the skin and soft tissues due to the neuropathic form of diabetic foot syndrome or chronic venous insufficiency, phase I-II of the wound process.

Read the detailed description

Diabetes takes the third place in the World in terms of its medical and social significance. Diabetes is often complicated with such urulent-inflammatory processe as diabetic foot syndrome. Urulent-inflammatory processes treatment takes a long time and medications due to microcirculation disorders, metabolic disorders, progressive hypoxia and a number of other factors. A moist wound environment, conducive to the natural process of wound cleansing (autolysis), regeneration of damaged tissue, and reduction of pain, irreversible sorption of excess exudate and toxic components and easy removal of the drug from the surface of the wound without additional trauma or damage are yhe main conditions of successful wound healing.Wound dressings made of fibrous polysaccharides modyfied with drugs meet these requirements. Foscelantan has prolonged antimicrobial, analgesic and reparative action, has the ability to transform on the wound surface into an amorphous gel-like mass, irreversibly bind wound detritus and pathological exudate, and provide optimal conditions for the process of wound healing.

Terms in these criteria, in plain language(11)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

What researchers measure

Primary outcomes

  1. Number of patients with trophic ulcers cured

    Number of patients cured

    Time frame: 15 days

Secondary outcomes

  1. percentage reduction in the non-epithelialized area of the wound surface in relation to the initial one

    Additionally, the percentage reduction in the non-epithelialized area of the wound surface relative to the original will be calculated, determined by digital non-contact planimetry during dressing changes. This indicator will be assessed using a digital camera and image analysis software

    Time frame: 15 days

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 25, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
