June 26, 2026 updated by: NuScience Medical Biologics, LLC

Evaluation of the Efficacy of Hyalomatrix® in the Healing of Chronic Venous Leg Ulcers: A Randomized Controlled Multicenter Crossover Trial

This is a randomized controlled trial evaluating the efficacy of HYALOMATRIX in conjunction with standard of care vs. standard of care alone in treating venous leg ulcers.

Study Overview

Status

Status

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

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

This research will take place across multiple medical centers, where both researchers and participants will know which treatment is being used (open label). Patients who agree to participate and meet the study requirements during screening will be randomly assigned to one of two groups: either standard of care (SOC) alone, or SOC plus Hyalomatrix. The study includes a crossover component for subjects in the SOC arm. At treatment visit 13 (approximately 84 days post-randomization), SOC arm subjects not having achieved complete wound closure, and still meeting the inclusion/exclusion criteria, are eligible to crossover to the IP arm (SOC plus Hyalomatrix). Crossover subjects will begin IP arm treatment with weekly Hyalomatrix applications for up to 12 treatment visits. The subject will continue follow-up per the original schedule. As this is a post-marketing study, it will gather information regarding the efficacy of treatment while also supporting insurance reimbursement decisions.

Phase

Phase

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Complete Wound Closure
Time Frame: 1-12 weeks
The primary endpoint will be the percentage of target wounds that achieve complete wound closure within 12 weeks.
1-12 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Weekly Percentage Area Reduction
Time Frame: 1-12 weeks
The percentage reduction in wound area from 1-12 weeks will be measured weekly using digital photographic planimetry and physical examination.
