Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 70 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Subject is at least 18 years of age but no more than 70 years of age.
  • Subject has at least two non-adjacent teeth in contralateral quadrants of the same jaw with an insufficient zone (< or = 1mm) of attached gingiva that requires soft tissue grafting. (1-3 teeth may be treated. In case of adjacent teeth requiring grafting, only one tooth at each site will act as test or control tooth, but all teeth will get the same treatment).
  • Root coverage is not desired at the time of grafting.
  • Females of childbearing potential must have a documented negative urine pregnancy test.
  • Subjects must have read, understood and signed an institutional review board (IRB) approved Informed Consent Form.
  • Subjects must be able and willing to follow study procedures and instructions.

Who cannot join

  • Subject with class III recession in the presence of a shallow vestibule or class IV recession.
  • Subject with vestibule depth of less than 7mm from base of recession.
  • Subject with any systemic conditions that could compromise wound healing and preclude periodontal surgery (i.e., diabetes mellitus, cancer, human immunodeficiency virus (HIV), bone metabolic diseases).
  • Subject who is currently receiving or has received within two months prior to study entry, systemic corticosteroids, immunosuppressive agents, radiation therapy, and/or chemotherapy which could compromise wound healing and preclude periodontal surgery.
  • Subject with the presence of acute infectious lesions in the areas intended for surgery.
  • Subject who has used any tobacco product within 3 months.
Show all 13Show fewer
  • Subject who is taking intramuscular or intravenous bisphosphonates.
  • Subject with only molar teeth suitable for soft tissue grafting.
  • Subject with teeth that have Miller Grade 2 or higher mobility.
  • Subject with known hypersensitivity to bovine collagen and/or iodine (shellfish allergy).
  • Subject who has received an investigational drug or biological/bioactive treatment within 30 days prior to study enrollment (medical or dental).
  • Subject who was previously treated with Gintuit, Dermagraft or any other skin graft at the target site(s) or immediately adjacent teeth.
  • Subject, who in the opinion of the investigator, for any reason other than those listed above, will not be able to complete the study per protocol.

About this study

Official title: A Clinical Trial to Evaluate Gintuit (TM) (Allogeneic Cultured Keratinocytes and Fibroblasts in Bovine Collagen) as an Alternative to Tissue From the Palate to Enhance Oral Soft Tissue Regeneration and Wound Healing

The purpose of this study is to evaluate Gintuit as a safe and effective alternative to palatal tissue in the treatment of subjects (with recession-type defects) who have an insufficient zone of attached gingiva associated with at least two nonadjacent teeth.

Being tested
Gintuit, Autologous palatal tissue
Medical subject headings
Gingival Recession

What participants receive

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

  • GintuitDevice

    Application of Gintuit at Day 0 to the gingival bed

  • Autologous palatal tissueOther

    Tissue will be harvested from the subject's palate and placed on the gingival bed

Receives: Device: Gintuit
2Active comparatorWithin-subject control: one side of mouth receives tissue harvested from the palate
Receives: Other: Autologous palatal tissue

What is being measured

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

  1. Percentage of Subjects With at Least 2 mm Keratinized Tissue (KT) at 6 Months at the Gintuit Treated Site.

    The superiority of Gintuit relative to a pre-defined standard (50% success) for a 2 mm KT threshold after six months.

    Measured: 6 months

Secondary outcomes (6)
  1. Color Same as Adjacent Tissues After 6 Months (Superiority)

    An examiner assessed color of both treated sites compared with the adjacent, non-treated tissue. The assessment was recorded as "More Red", "Equally Red", or "Less Red" as compared to adjacent, non-treated tissue. A match in color with the surrounding tissue is considered a positive aesthetic outcome.

    Measured: 6 months

  2. Texture Same as Adjacent Tissues After 6 Months (Superiority)

    An examiner assessed texture of both treated sites compared with the adjacent, non-treated tissue. The assessment was recorded as "More Firm", "Equally Firm", or "Less Firm" as compared to adjacent, non-treated tissue. A match in texture with the surrounding tissue is considered a positive aesthetic outcome.

    Measured: 6 months

  3. Percentage of Subjects With at Least 1 mm Keratinized Tissue (KT) at 6 Months at the Gintuit Treated Site.

    The superiority of Gintuit relative to a pre-defined standard (80% success) for a 1 mm KT threshold after six months.

    Measured: 6 months

  4. Patient Preference After 6 Months/Early Termination (Superiority)

    Number of patients expressing preference for Gintuit.

    Measured: 6 months

  5. Surgical Site Sensitivity Mild or Absent After 1 Week(Superiority)

    The sensitivity of Gintuit, Free Gingival Graft (FGG) and palatal donation sites was assessed with a puff of air and rated by the Investigator as none, mild, moderate or severe sensitivity. The sensitivity of Control was determined as the most sensitive of FGG and palatal donation sites.

    Measured: 6 months

  6. Pain Absent After 3 Days (Superiority)

    Pain Assessment(Modified Intent-to-Treat Population)

    Measured: Day 3

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Gintuit and Autologous palatal tissue in people with Gingival Recession, run by Organogenesis 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 6 inclusion and 13 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 8 Nov 2012. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 8 Nov 2012). 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?

Percentage of Subjects With at Least 2 mm Keratinized Tissue (KT) at 6 Months at the Gintuit Treated Site. (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00587834, which also lists 1 linked publication.

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 8 Nov 2012.
