Polydeoxyribonucleotide (PDRN) for Cuff Regeneration

June 18, 2022 updated by: Jung-Taek Hwang, Chuncheon Sacred Heart Hospital

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

16 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: PDRN(polydeoxyribonucleotide)
polydeoxyribonucleotide 3cc at surgery under arthroscopy guidance and 2 weeks after surgery under ultrasound guidance
Drug: Polydeoxyribonucleotides
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.
Other Names:
  • PDRN
Placebo Comparator: CONTROL(normal saline)
normal saline 3cc at surgery under arthroscopy guidance and 2 weeks after surgery under ultrasound guidance
Drug: Normal saline
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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
American Shoulder and Elbow score
Time Frame: 2 years
functional score of shoulder between 0 to 100(0: bad, 100: good)
2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Constant score
Time Frame: 2 years
functional score of shoulder between 0 to 100(0: bad, 100: good)
2 years
