Study summary

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.

Read the 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.

  9. Subject is pregnant or breastfeeding
  10. Subject with history of treatment (systemic >10mg daily dose), cytotoxic chemotherapy, or topical steroid application to the wound surface for >2 weeks duration within 30 days prior to randomization; or anticipated use of the above during the course of the study

  14. HBOT within 14 days prior to randomization
  15. Revascularization surgery on the index wound leg within 30 days of screening phase
  16. Index wound suspicious of neoplasm in the opinion of the principal investigator
Terms in these criteria, in plain language(9)

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.

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.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

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.

What researchers measure

Primary outcomes

  1. Complete Wound Closure

    The primary endpoint will be the percentage of target wounds that achieve complete wound closure within 12 weeks.

    Time frame: 1-12 weeks

Secondary outcomes

  1. Weekly Percentage Area Reduction

    The percentage reduction in wound area from 1-12 weeks will be measured weekly using digital photographic planimetry and physical examination.

    Time frame: 1-12 weeks

  2. Pain Assessment

    Change in pain associated with the target wound will be assessed using the Numeric Pain Rating Scale throughout the study. Numeric Rating on a scale of 0-10. o is No pain and 10 is the worst possible pain.

    Time frame: 1-14 weeks

Other outcomes

  1. Time to Closure

    Average number of grafts/weeks used to achieve wound closure

    Time frame: 1-12 weeks

  2. Follow-Up Closure

    Number of wounds that re-opened during the 2-week follow-up

    Time frame: 2 weeks

  3. Adverse Events and Serious Adverse Events

    The number and nature of adverse events (AEs) and serious adverse events (SAEs) occurring during the study will be tracked and reported.

    Time frame: 1-12 weeks
