  • 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 Miller Class I or II buccal recession (≥ 3 mm) that requires soft tissue grafting. (Teeth may be treated with a maximum difference of 2 mm with respect to depth and width).
  • Females of childbearing potential must have a documented negative urine pregnancy test and must agree to continue acceptable methods of contraception for 6 months post surgery.
  • Subjects must have read, understood and signed an institutional review board (IRB)-approved Informed Consent Form (ICF).
  • Subjects must be able and willing to follow study procedures and instructions.

Who cannot join

  • Subject has extremely prominent root surfaces (> 1/2 the diameter of the root facial to cortical plate).
  • Subject has interproximal attachment loss beyond the CEJ.
  • Subject with teeth that have a Miller Grade 2 or higher mobility.
  • Subjects with Class V restorations.
  • Subjects with crowns on the teeth selected for treatment.
  • Subjects who have had endodontic therapy in the last 6 months on the teeth selected for treatment.

  • Subjects who have used any tobacco product within the past 3 months.
  • Subjects with only molar teeth suitable for soft tissue grafting.
  • Subject has probing pocket depth >/= 4 mm at either surgical site.
  • Female subjects who are pregnant or lactating.
  • Subjects with any systemic conditions (i.e., uncontrolled diabetes mellitus, cancer, HIV, bone metabolic diseases) that could compromise wound healing and preclude periodontal surgery.
  • Subjects who are currently receiving or have 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.
  • Subjects with the presence of acute infectious lesions.
  • Subjects taking intramuscular or intravenous bisphosphonates.
  • Subjects with a known hypersensitivity to bovine collagen and/or iodine (shellfish allergy).
  • Subjects who have received an investigational drug, device or biological/bioactive treatment within 30 days prior to study enrollment (medical or dental).
  • Subjects previously treated with Apligraf/CelTx, Dermagraft or any other cell-based product, including autologous tissue at the target site(s) or immediately adjacent teeth.
  • Subjects, 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 Prospective, Randomized, Controlled Pilot Study of CelTx(TM) (Apligraf®) as an Alternative to Tissue From the Palate in the Treatment of Gingival Recession Requiring Root Coverage

The purpose of this study is to evaluate CelTx as an alternative to tissue from the palate in the treatment of subjects with Miller Class I or II recession defects who desire root coverage. It is anticipated that this study will demonstrate that CelTx is a safe alternative to palatal tissue and demonstrate potential to enhance oral soft tissue regeneration and wound healing.

What is being measured

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

  1. Overall Rate of Adverse Events (AEs)

    Adverse events were collected at every visit throughout the 6 month duration.

    An AE is defined as any adverse change in the subject's medical status when compared with the subject's baseline condition, whether or not the event is related to the study device or a study procedure; or an exacerbation (either in frequency or severity) in a subject's pre-existing condition.

    Measured: 6-month

Secondary outcomes (4)
  1. Periodontal Health Measures

    Measured: 6-months

  2. Aesthetic Measures

    Measured: 6-months

  3. Post-Surgical Subject Comfort Measures

    Measured: 4-weeks

  4. Subject Preference Measures

    Measured: 6-months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing CelTx and Autologous sub-epithelial connective tissue graft in people with Gingival Recession, run by Organogenesis at 1 site 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 5 inclusion and 18 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: stopped early, as of the sponsor's last update on 11 Jan 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 21 Nov 2011). 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?

Overall Rate of Adverse Events (AEs) (time frame: 6-month). 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 11 Jan 2012.
