Study summary

This study is a prospective, single center, postmarket study to evaluate the safety and effectiveness of NeoPatch used as a tissue cover in foot and ankle tendon revision and repair surgery.

Read the detailed description

This study is a prospective, single center, postmarket study to evaluate the safety and effectiveness of NeoPatch used as a tissue cover for chronically injured tendons requiring surgical revision. NeoPatch is a tissue covering derived from terminally sterilized, dehydrated human placental membrane tissue comprised of both amnion and chorion. Candidates for this study are patients presenting with chronic tendon pain that are being evaluated for primary tendon revision surgery following failure of standard of care or immediate need for surgery, as determined by the investigator. Consented patients will receive NeoPatch as an adjunct to their foot or ankle tendon revision; NeoPatch will be wrapped around the tendon immediately prior to closure. The study will be divided into two phases: Screening and Follow-up. The study will include prospective patient evaluations at scheduled clinic visits and ultrasound appointments for a maximum of 12 visits over 12 months. Patient history, medications, self-reported pain, tendon status, and adverse events will be collected on all patients consented and enrolled into the study.

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

  • Chronic tendinopathy requiring surgical revision in the opinion of the Investigator as defined in Appendix G.
  • Intention to schedule surgical revision.

    ≥ 18 years.

  • Free from clinical signs of infection at time of screening and at time of surgical intervention.
  • Target tendon is one of the following: Achilles, Extensor Digitorum Longus, Extensor Hallucis Brevis, Extensor Hallucis Longus, Flexor Digitorum Longus, Flexor Hallucis Longus, Tibialis Anterior, Tibialis Posterior, Peroneus Longus, Peroneus Brevis, Peroneus Tertius.
  • Able and willing to provide consent and comply with protocol.

Exclusion criteria

Exclusion Criteria:

  • History of surgical intervention involving target tendon.
  • Tendon injury is acute in nature.
  • Current participation in another clinical study.
  • Currently receiving radiation or chemotherapy.
  • Diagnosis of connective tissue disease requiring systemic immunomodulatory therapy; stable NSAID doses for mild rheumatoid arthritis permitted.
  • Use of biomedical growth factor within previous 30 days.
  • Pregnant or breastfeeding or planning on becoming pregnant or unwilling to use medically acceptable methods of .
  • Taking medications considered to be immune system modulators within previous 30 days.
  • Patient taking specific Cox-2 inhibitors within previous 30 days.
  • Currently being treated with an device or drug (within 3 months prior to surgery).
  • Allergy, intolerance or to any components or packaging of the product.
Terms in these criteria, in plain language(4)

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.

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.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Sep 2017 to primary completion in Dec 2018, 15 months.

Of 183 interventional studies with no phase under Tendinopathy, half reached primary completion within 20 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 37. This study's 15 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 24, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
