About this study

Official title: Effect of Polydeoxyribonucleotide (PDRN) on Healing and Fatty Degeneration of Rotator Cuff in Human

This study is to evaluate the effect of polydeoxyribonucleotide (PDRN) for healing and fatty degeneration of rotator cuff. The investigators will enroll 130 patients with rotator cuff tear who will undergo arthroscopic rotator cuff repair. 130 patients will be classified into two group. One group (PDRN) will be injected at the repaired cuff with 3cc polydeoxyribonucleotide just after surgery and be injected with another 3ml polydeoxyribonucleotide under ultrasound guidance 2 weeks after the surgery. The other group (CONTROL) will be injected with 3ml normal saline in the same manner.

Read the detailed description

Polydeoxyribonucleotide is a tissue regeneration activator. It binds an adenosine receptor and stimulate VEGF(vascular endothelial growth factor) synthesis and stimulate collagen synthesis. Nowadays, a lot of arthroscopic rotator cuff repairs are being performed. but the failure rate of rotator cuff repair is considerably high. Therefore, this study is to evaluate the effect of polydeoxyribonucleotide for healing and fatty degeneration of rotator cuff.

Visual analog scale (VAS) of pain and other functional scores of the two group will be checked preoperatively and postoperative 3, 6, 12, 24 months. Growth factors (VEGF, fibroblast growth factor(FGF), insulin like growth factor(IGF)) will be checked preoperatively and postoperative 1h, 2 days, 2 weeks, 6 weeks, 3, 6 months. Follow up MRI will be checked at postoperative 6 months. The parameters will be compared using statistical analysis.

What participants receive

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

  • PolydeoxyribonucleotidesDrug

    Also called PDRN

    Just after arthroscopic rotator cuff repair, 3cc polydeoxyribonucleotide will be injected, and 2 weeks after the surgery the same amount of the material will be injected.

  • Normal salineDrug

    Just after arthroscopic rotator cuff repair, 3cc normal saline will be injected, and 2 weeks after the surgery the same amount of the material will be injected.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Polydeoxyribonucleotides and Normal saline in people with Rotator Cuff Tear, run by Chuncheon Sacred Heart Hospital at 1 site in South Korea.

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 2 inclusion and 2 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 24 Jun 2022. 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 South Korea. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

American Shoulder and Elbow score (time frame: 2 years). 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 NCT03916198, which also lists 3 linked publications.

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 24 Jun 2022.
