About this study

Official title: The Value of Autologous Tenocyte Implantation in Patients With Chronic Achilles Tendinopathy: a Double-blind Randomised Clinical Trial

This study is designed to compare the treatment of 2 groups in patients with Achilles tendinopathy: autologous tenocytes injection in combination with exercises versus saline injection in combination with exercises

Read the detailed description

Overuse injury of the Achilles tendon is a common entity. When the exact origin of tendon pain is unclear, the term tendinopathy is preferred. Most accepted treatment at this moment is an eccentric exercise programme, according to the Dutch guidelines. However, a recent systematic review on the effectiveness of eccentric exercises to treat lower extremity tendinoses concluded that it is unclear whether eccentric exercises are more effective than other forms of treatment. Recent studies described new treatment strategies in tendinopathies, such as the use autologous Tenocyte Implantation (ATI). This treatment option can participate actively in tissue repair processes on cell level. The only published clinical pilot study in tendon research reported 60% improvement in all scores after 6 months follow-up.

What is being measured

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

  1. VISA-A score

    a validated instrument to detect the severity of symptoms in patients with Achilles tendinopathy

    Measured: 24 weeks

Secondary outcomes (3)
  1. Ultrasonographic tendon repair - Ultrasonographic Tissue Characterization (UTC)

    UTC provides quantitative information on tendon fiber alignment and the related ultra-structural integrity of the tendon tissue through a non-invasive approach and is used in several clinical trials in humans

    Measured: 24 weeks

  2. Subjective patient satisfaction

    Patient satisfaction will be determined by asking the patient how satisfied he/she is with the effect of the treatment in 4 possible categories: excellent / good / moderate / poor. The groups "excellent" and "good" will be regarded as successful and the groups of "moderate" and "poor" as not successful.

    Measured: 24 weeks

  3. Returning to sports level

    The patient will be asked whether they are able to return to their sports level. It is a subdivision in 5 groups: A. No sports; B. No return in sports; C. Returning in sports but not in desired sport; D. Returning in desired sport, but not yet old level; E. Returning to old level in desired sport.

    Measured: 24 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Autologous Tenocyte Implantation and Saline in people with Tendinopathy and Achilles Tendon Injury, run by Erasmus Medical Center at 1 site in Netherlands.

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 3 inclusion and 11 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 16 Feb 2015. 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 Netherlands. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

VISA-A score (time frame: 24 weeks). 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 NCT01343836, 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 16 Feb 2015.
