Study summary

This is an observational study designed to evaluate the safety and clinical outcomes of Myriad™ in soft tissue reconstruction procedures. The study will enroll participants who are undergoing a surgical procedure, where the attending physician will use Myriad™ as part of the surgical intervention.

Read the detailed description

This is an observational, multi-center, single arm, Phase IV study, designed to evaluate the safety and clinical outcomes of Matrix and Morcells in soft tissue reconstruction procedures.

The study is a registry study and will enroll participants who are undergoing a surgical procedure, and where the attending physician will use Myriad Matrix™ and/or Morcells™ as part of the surgical intervention.

Participants enrolled in the study will be undergoing a range of surgical procedures involving the reconstruction of soft tissues, including but not limited to:

  • Abdominal dehiscence
  • Necrotizing soft tissue infection (NSTI)
  • Lower extremity complex non-healing wounds (limb salvage)
  • Pilonidal sinus disease
  • Anal fistula
  • Hidradenitis suppurativa reconstruction
  • Pressure injury reconstruction

Other procedure types may be included at the discretion of the Investigator/Research Team.

Participants that are being enrolled in the study would otherwise be undergoing their surgical procedure with either of the Myriad™ devices as part of Standard of Care (SoC).

The pre-operative care and preparation of the surgical site (prior to the application of Myriad™ devices) shall be undertaken at the discretion of the attending physician and per their institutional protocols and procedures. Surgical technique for the participants reconstruction is at the discretion of the attending physician. Use of Myriad Matrix™ or Morcells as part of the surgery shall be per the products Instructions for Use. Myriad Matrix™ devices may be implanted or used for dermal regeneration as part of the participants surgical procedure. Myriad Morcells™ may be used for dermal regeneration and in combination with the Myriad Matrix™ devices. The participants post-operative care is at the discretion of the attending physician.

Early and late-stage healing outcomes will be assessed as part of the study and as part of standard of care.

Through the course of treatment and following up care de-identified patient data (quantitative qualitative assessment measures and digital images) will be captured and from the basis of the registry dataset.

Study population

The study is being carried out at approximately 10 sites in the U.S. Across all sites, about 300 individuals will participate in the study where the Investigator is planning to utilize Myriad™ as a part of their surgical procedure.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Willing and able to provide written and to comply with the requirements of Clinical Plan
  • Male or female patients aged 18 years or above
  • Patients where Matrix and/or Morcells were used as part of their soft tissue reconstruction procedure
  • Subject that are willing and able to comply with all aspects of the treatment and evaluation schedule

Exclusion criteria

Exclusion Criteria:

  • Patients with known sensitivity to ovine (sheep) derived material
  • Patients with full thickness ('third degree') burns
  • Patients with wounds with uncontrolled clinical infection (CDC Contamination Grade=4)
  • Any medical condition or serious intercurrent illness that, in the opinion of the investigator, may make it undesirable for the patient to participate in the study
  • Patient is currently participating or has participated in another clinical study within past 30 days prior to enrollment
  • Pregnant or lactating women
  • Any subject who, at the discretion of the Investigator, is not suitable for inclusion in the study
Terms in these criteria, in plain language(2)

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.

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.

What researchers measure

Primary outcomes

  1. Proportion of participants with treatment emergent adverse events during the study

    Nature, frequency, and severity of adverse events

    Time frame: 3 years

Secondary outcomes

  1. Time (weeks) to complete healing
