About this study

Official title: Pilot Study - Effectiveness of Omnigen in Addition to Standard Treatment in Treating Diabetic Foot Ulcers (DFU)

The Omnigen Pilot study aims to provide an evidence base for Omnigen as a treatment for Diabetic Foot Ulcers (DFU). It aims to achieve this by tailoring a regenerative therapy used for ocular surface repair to provide proactive non-surgical wound management of Diabetic Foot Ulcers (DFU).

Read the detailed description

This pilot study is designed as a multi-centre prospective, patient and observer blind, randomised controlled trial, recruiting patients from two clinical centres across the East Midlands; Derby Teaching Hospitals NHS Foundation Trust (DHFT) and Nottingham University Hospitals NHS Trust (NUH).

Eligible patients will be approached within diabetic foot clinics by their usual clinical carers to determine whether they are interested in participating in the study. They will be provided with written information about the study and the researcher will explain the study verbally to them and address any questions and concerns the patient may have. Patents will be given at least 24 hours to consider taking part in the trial before signing a consent form.

After informed consent has been given, baseline information will be collected. This will include demographic information, medical history and concomitant medication. eGFR and HbA1c will also be collected if not done within previous 3 months as part of standard care. The baseline wound status, assessment of ulcer infection according to Infectious Diseases Society of America (IDSA) criteria, peripheral pulses, neuropathy and ankle brachial pressure index will also be taken.

Participants will then be randomised to receive either standard of care or Omnigen graft with standard of care. Staff administering the Omnigen product will be aware of which treatment the participant is receiving however the participant and the research staff conducting the healing assessments will be blinded to their treatment allocation. Therefore the participant and the assessors will be blinded to the treatment given in order to minimize any bias in the collection of healing outcome data. For those randomized into the control arm, 'Dummy Packaging' will be used to ensure the blind is maintained.

Patients will be seen two weekly from their baseline visit until healing for up to 12 weeks and at 2 weeks post healing in those that heal. If a participant's foot ulcer heals before the final 12 weeks visit, they will attend a healing confirmation visit two weeks post the original heal date, however will not be required to attend any further fortnightly visits until the final blinded assessment visit at week 12 . If the participant's foot ulcer has not healed at 12 weeks then a blinded assessment should still be conducted at this time point.

Data is collected using the Dacima Clinical Suite Electronic Data Capture (EDC) software (Dacima Software Inc.)

What participants receive

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

  • OmnigenOther

    For those randomised onto the investigational arm, a dual layer of the Omnigen product will be applied at baseline and at every fortnightly trial visit until healing or the end of the 12 week period whichever occurs first, according to the standard study procedure.

  • Dummy PackagingOther

    For those randomised into the control arm, dummy packaging will be opened at the time of application of standard of care, to ensure the same experience is received to those on the experiential arm.

What is being measured

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

  1. The primary outcome is wound healing (defined as full epithelialisation without drainage maintained for 2 weeks) within 12 weeks of starting study treatment.

    To assess the whether higher proportion of wounds heal at 12 weeks in the investigational arm to the control arm - assessed by confirmation of healing at 12 week visit.

    Measured: 12 weeks

Secondary outcomes (8)
  1. Overall reduction in wound size (surface area, assessed by acetate tracing)

    To assess the whether higher proportion of wounds reduce in size at 12 weeks in the investigational arm to the control arm - assessed by comparing acetate tracing in each arm.

    Measured: 12 weeks

  2. Time to healing (weeks) for those that heal within 12 weeks,

    To assess the whether higher proportion of wounds heal at 12 weeks in the investigational arm to the control arm - assessed by proportion of confirmation of heeling visits conducted at 12 weeks within each arm.

    Measured: 12 weeks

  3. Proportion of wounds healed within 6 weeks

    To assess the whether higher proportion of wounds heal at 6 weeks in the investigational arm to the control arm - assessed by proportion of confirmation of heeling visits conducted at 6 weeks within each arm.

    Measured: 6 weeks

  4. Adverse events (safety) including major and minor amputations and hospitalisation

    To assess the safety of the intervention of Omnigen in comparison to standard of care. Review of SAEARs.

    Measured: 12 weeks

  5. Incidence of secondary infection

    To assess the safety of the intervention of Omnigen in comparison to standard of care. Review of SAEARs.

    Measured: 12 weeks

  6. Feasibility of recruitment

    To assess the feasibility of the study in regards to recruitment for a future full RCT. Recruitment rate, reasons for patients not randomising and reasons for investigators not randomising. Screening logs/protocol deviations.

    Measured: 12 weeks

  7. Pain in the area of the ulcer as assessed by patient completed VAS

    To assess pain of ulcer through completion of VAS at every fortnightly visit to identify if pain reduces at a higher rate on the interventional arm than the control arm.

    Measured: 12 weeks

  8. Effectiveness of participant blind

    To assess whether the blinding to arm allocation has been successful with the use of dummy packaging or whether the participants are able to identify which treatment they have received. This will be done by completion of a participant questionnaire at the end of the study.

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Omnigen and Dummy Packaging in people with Diabetic Foot Ulcers, run by University Hospitals of Derby and Burton NHS Foundation Trust at 2 sites in United Kingdom.

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 6 inclusion and 14 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 9 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United Kingdom. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

The primary outcome is wound healing (defined as full epithelialisation without drainage maintained for 2 weeks) within 12 weeks of starting study treatment. (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 9 Jan 2020.
