ChitoCare Medical Wound Healing Gel PMCF Study on Healing of Chronic Wounds (CHITOCHRONIC)

February 17, 2025 updated by: Primex ehf

A Multi-Centre, Randomized, 2-arm, Open-labelled, Controlled PMCF Study to Evaluate the Safety and Performance of ChitoCare Medical Wound Healing Gel in Healing of Chronic Wounds

We are testing a gel intended for the protection and healing of chronic wounds as a support for standard therapy. The main component of the gel is chitosan, a natural polymer that has the ability to stop bleeding, has a positive effect on wound healing, and has antimicrobial properties.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this PMCF study is to evaluate the safety and efficacy of ChitoCare medical Wound Healing Gel for the healing of chronic wounds. The study will enroll patients with diabetic foot ulcer, venous ulcer or pressure ulcer. Patients will be randomly assigned to an active or control group. The active group will apply the gel to the wound, in addition to the standard of care, while the control group will receive only standard care. The study will last from 3 to 18 months for an individual patient (15-month recruitment period and 3 months of follow-up after the last patient is enrolled) or until event occurrence (complete wound healing/exclusion from the study). The study envisages four visits: Visit 1 - Screening and Inclusion visit, Visit 2 (after 4 weeks), Visit 3 (after 12 weeks) and Visit 4 - End of Study Visit: The final visit will take place when the event occurs (complete healing/exclusion from study). On each visit, the patients will have their wound photographed and assessed after debridement. Adverse events will be followed throughout the whole study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

    • Size of the wound ≥ 0.5 cm2
    • Wound is not infected at the time of randomization
    • Wound is present for at least 4 weeks
  4. Able to understand and comply with the requirements of the study

Exclusion Criteria:

  1. Patients with serious concomitant disease (cancer, heart failure (NYHA class IV), severe anaemia (Hb<100 g/L), neoplasia)

  3. Patients that will require surgical procedure to treat their ischemic condition on the limb where the wound is present as assessed by the investigator
  4. Patients diagnosed with autoimmune connective tissue diseases
  5. Previous treatment under this clinical protocol
  6. Participation in another clinical trial
