About this study

Official title: A Multi-Center, Prospective, Open Label Safety Trial of the RedDress Wound Care System (RD1) in Management of Texas 1a or 2a Neuropathic Diabetic Foot Ulcers.

The purpose of this study is to assess the safety of the RedDress Wound Care System (RD1) in patients Texas 1a or 2a Neuropathic Diabetic Foot Ulcers.

Read the detailed description

The investigational product, the RD1 kit, was designed to enable a care provider to create an in vitro blood clot from the patient's own blood at the point of care, in a safe and effective manner.

While many advanced modalities of treatment have been developed to heal chronic DFUs (as well as other types of chronic wounds), the vast majority have been approved for relatively non-severe wounds (e.g., Texas 1a/2a grades) and relatively healthy subjects in controlled clinical trials and typically exclude 25-75% of subjects who have several comorbidities and severe wounds. Moreover, when the results of such trials (and other trials of advanced modalities) have been subject to a systematic review, the strength of the evidence for their efficacy has been rated low or even insufficient to judge. Consequently, there is an urgent need for new technologies to be tested that can improve healing rates in all classes of chronic DFUs.

The study is a multi-center, prospective, single group safety study, consisting of 20 subjects who will complete the study (note: if any patients are lost to follow-up or withdrawn, enrollment will increase to compensate for loss of these subjects). The subjects will receive 12 weekly RD1 applications. Subject data will be kept in each site's records.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants Experiencing Adverse Events

    Adverse event rate will be calculated including serious adverse events (SAEs), adverse events (AEs) (including any lack of venous access events), and device-related adverse events (DRAEs) (safety population and ITT populations).

    Measured: 12 weeks

Secondary outcomes (3)
  1. Number of Participants Experience Complications Due to Lack of Venous Access

    For all patients for all 12 visits involving RD1 procedure (ITT population)

    Measured: 12 weeks

  2. Number of Participants Achieving a Complete Wound Closure at 12 Weeks

    Defined as skin re-epithelialization without drainage or dressing requirements confirmed at 2 consecutive study visits 2 weeks apart) for DFU treated with RD1 (ITT population).

    Measured: 12 weeks

  3. Percent of Reduction in Wound Size Over 12 Weeks (ITT Population)

    The data will also be plotted graphically week by week. Week 12 data will be used to recalculate sample size for the pivotal trial

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing RedDress Wound Care System (RD1) in people with Neuropathic Diabetic Ulcer - Foot, run by RedDress Ltd. at 4 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 14 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Nov 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants Experiencing Adverse Events (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Dec 2020; AzTrials last refreshed its copy on 7 Nov 2026.
