About this study

Official title: Does Autologous Conditioned Plasma Enhance Rotator Cuff Tendon Healing After Surgery? A Radomized Control Trial.

The aim of this study is to establish if the application of autologous conditioned plasma (ACP), also described as platelet rich plasma (PRP), to the site of supraspinatus tendon repair beginning within two weeks of surgery, can improve patient outcomes over the course of 12 months. These outcomes will be measured by post-surgical pain and function scores, shoulder strength and range of motion (ROM), and radiological parameters of tendon healing. Outcome measures will be compared to a control group of patients receiving placebo injections following surgery (saline plus local anaesthetic).

This study is significant for being the first double blind randomised control trial, using two PRP injections to examine the efficacy of a PRP preparation following surgical repair of supraspinatus tendon. The objective is to prolong and enhance the tendon healing response initiated by surgery.

The research hypothesis is that enhanced tendon healing following the PRP injections will lead to more rapid rehabilitation and lower rates of re-rupture of the repaired tendon compared to the control group.

What participants receive

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

  • Autologous conditioned plasma (ACP)Other

    Also called Platelet rich plasma (PRP)

    10ml of patient's own venous blood is aspirated. ACP (1ml) (extracted from centrifuged venous sample), with additional calcium chloride is then injected into the tendon-bone junction and adjacent area under guided ultrasound.

    • First injection at approximately 10 days post-operatively
    • Second Injection at approximately 21 days post-operatively
  • PlaceboDrug

    10ml of patient's own venous blood is aspirated. The syringe is centrifuged in a proprietary closed unit (Arthrex Medical Company) for 5 minutes. The venous blood sample will be discarded and a placebo (1ml saline + local anaesthetic) is injected to the surrounding tissue, but not into the tendon, under guided ultrasound.

    • First injection at approximately 10 days post-operatively
    • Second Injection at approximately 21 days post-operatively

Study groupRoleWhat they receive
Autologous conditioned plasma (ACP)Active comparator10ml of patient's own venous blood is aspirated. The syringe is centrifuged in a proprietary closed unit (Arthrex Medical Company) for 5 minutes. The red blood cells will be discarded, and the supernatant containing ACP (with additional CaCl to activate the ACP and local anaesthetic) is injected into the tendon bone junction and adjacent area under ultrasound guidance. No adverse consequences are anticipated by using the Arthrex ACP injection. * First injection at approximately 10 days post-operatively * Second Injection at approximately 21 days post-operatively Other Names: Platelet rich plasma (PRP)

What is being measured

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

  1. Changes in magnetic resonance imaging (MRI) score over time

    MRI will assess the dimensions of the supraspinatus tear pre-operatively. MRI will assess the tendon healing of the supraspinatus tendon post-operatively at 12 months

    Measured: Pre-operatively, and 12 months post-operatively

Secondary outcomes (7)
  1. Changes in shoulder range of motion over time

    Shoulder range of motion measures will include:

    • internal humeral rotation of the affected arm
    • external humeral rotation of the affected arm
    • forward flexion of the affected arm
    • abduction of the affected arm

    Measured: pre-operatively, 3 months post-operatively, 6 months post-operatively, 12 months post-operatively

  2. Changes in strength of the shoulder musculature over time

    Muscular strength will be measured through:

    • internal humeral rotation of the affected arm
    • external humeral rotation of the affected arm
    • forward flexion of the affected arm
    • abduction of the affected arm

    Measured: 6 months post-operatively, 12 months post-operatively

  3. Changes in the visual analogue scale (VAS) for pain over time

    The VAS is a scale from 1 to 10 and requires the patient to rate their pain along the scale; with 0 equating to no pain and 10 equating to the worst possible pain.

    Measured: Pre-operatively, 1st injection post-operatively, 2nd injection post-operatively, 6 weeks post-operatively, 12 weeks post-operatively, 6 months post-operatively, 12 months post-operatively

  4. Changes in the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire over time

    The QuickDASH is a shortened version of the Disabilities of the Arm Shoulder and Hand (DASH) outcome measure. It uses 11 items instead of the original 30 items to measure physical function and symptoms in persons with any or multiple musculoskeletal disorders of the upper arm.

    Measured: Pre-operatively, 6 weeks post-operatively, 12 weeks post-operatively, 6 months post-operatively, 12 months post-operatively

  5. Changes in the Oxford Shoulder Score (OSS) over time

    The OSS is a self-reported questionnaire developed to evaluate disability in those with injuries and impairment of the rotator cuff.

    Measured: Pre-operatively, 6 weeks post-operatively, 12 weeks post-operatively, 6 months post-operatively, 12 months post-operatively

  6. Changes in the Simple Shoulder Test (SST) over time

    The SST consists of a series of 12 "yes" or "no" questions regarding function of the involved shoulder.

    Measured: Pre-operatively, 6 weeks post-operatively, 12 weeks post-operatively, 6 months post-operatively, 12 months post-operatively

  7. Changes in the Short Form - 12 health questionnaire (SF-12) over time

    The SF-12 is a shortened version of the Short Form-36 (SF-36). It uses 12 items instead of 36, to measure general functional health and well-being from the patient's point of view.

    Measured: Pre-operatively, 6 weeks post-operatively, 12 weeks post-operatively, 6 months post-operatively, 12 months post-operatively

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Autologous conditioned plasma (ACP) in people with Supraspinatus Tear, run by The University of Western Australia at 1 site in Australia.

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 4 inclusion and 7 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: status not confirmed, as of the sponsor's last update on 9 Dec 2014. 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 Australia. 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 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?

Results are not available in the source record.

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?

Changes in magnetic resonance imaging (MRI) score over time (time frame: Pre-operatively, and 12 months post-operatively). 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 NCT01414764, 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 9 Dec 2014.
