What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine whether Connective Tissue Matrix (a natural tissue supplement) or a steroid injection better treats rotator cuff tendinopathy, a condition causing shoulder pain and limited movement. Participants will receive one of these treatments through random selection, and neither they nor the researchers will know which treatment is administered, ensuring unbiased results. Eligible participants are those experiencing shoulder issues due to rotator cuff tendinopathy and willing to receive an injection as part of their treatment. As an unphased trial, this study offers the opportunity to contribute to valuable research that could enhance treatment options for rotator cuff tendinopathy.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, if you have a history of chronic steroid treatment, you may not be eligible to participate.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that the Connective Tissue Matrix (CTM) is generally safe for people. Previous studies have not identified any major safety issues or serious side effects from its use. The CTM, a type of allograft made from human tissue, is designed for injection to help repair or replace damaged tissue.

Corticosteroids, such as Kenalog-40 used in the trial, commonly treat inflammation and are known to be safe when used properly. Some individuals might experience side effects, including temporary pain at the injection site or mood changes.

Overall, past research suggests both treatments in the trial are safe. However, discussing any concerns or questions with the study team or a healthcare provider is always important. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Unlike traditional treatments for rotator cuff tendinopathy, which often involve corticosteroid injections to reduce inflammation, the CTM Boost treatment uses a novel approach with a decellularized Human Cellular and Tissue Based Allograft derived from placental connective tissue. This innovative treatment is designed to supplement or replace damaged connective tissue rather than just addressing inflammation. Researchers are excited about CTM Boost because it offers a new mechanism of action by potentially enhancing tissue repair and regeneration, which could lead to more sustainable improvements in shoulder function and pain relief. Additionally, the use of biological materials in this way may reduce some of the side effects associated with long-term steroid use.

What evidence suggests that this trial's treatments could be effective for rotator cuff tendinopathy?

Research has shown that Connective Tissue Matrix (CTM), a treatment under study in this trial, might aid tendon repair by creating a supportive environment for cell growth and healing. Early results suggest that CTM can reduce pain and improve movement in individuals with rotator cuff problems by forming a framework that facilitates tissue repair. This trial will compare CTM to corticosteroid injections, another treatment option often used to reduce swelling and provide short-term pain relief for similar issues. However, steroids may not support long-term healing as effectively as CTM. Overall, current evidence suggests that CTM is a promising option for treating rotator cuff tendinopathy. ^{1 6 7 8 9}

Trial Overview

The study compares two treatments for shoulder pain from rotator cuff tendinopathy: an injection of Connective Tissue Matrix (CTM) versus a standard steroid shot. Patients will be randomly assigned to one of these treatments without knowing which one they receive.

How Is the Trial Designed?

Group I: CTM Boost Experimental Treatment 1 Intervention

TM Boost (CTM Biomedical, Miami, FL) is a decellularized Human Cellular and Tissue Based Allograft (HCT/P) derived from placental connective tissue. It is marketed as an allograft for homologous use to supplement or replace damaged or inadequate connective tissue. It is regulated as a minimally-manipulated biologic by the FDA and is marketed as an allograft for homologous use to supplement or replace damaged or inadequate connective tissue. It is administered applied into the tissue via injection. Participant will undergo a single injection of 2.0cc of the injectable CTM allograft, administered using a 20G needle in the subacromial space. 3mL of ropivacaine will be mixed into the syringe prior to administration of the injection. Posttreatment pain control (hydrocodone/acetaminophen #20 5/500 mg) will be used.

Group II: Corticosteroid Placebo Group 1 Intervention

Kenalog-40 is a long-acting corticosteroid injection for intramuscular (into the muscle) or intra-articular (into the joints) use. It may be used to treat many different types of inflammatory conditions. In this study, a 2.0cc dose injection of Kenalog-40 will be administered directly into the subacromial space using a 20G needle. 3mL of ropivacaine will be injected along with the steroid (as part of the same injection). Posttreatment pain control (hydrocodone/acetaminophen #20 5/500 mg) will be used.

Published Research Related to This Trial

Intralesional platelet-rich plasma (PRP) injections significantly reduced tear size in partial-thickness rotator cuff tears compared to subacromial corticosteroid (CS) injections, with PRP showing a reduction of 3.39 mm in the coronal plane and 2.97 mm in the sagittal plane.

Patients receiving PRP also experienced better functional improvements in shoulder scores after 6 months compared to those receiving CS injections, indicating that PRP may be a more effective treatment option for enhancing recovery in these injuries.

In a study involving 60 rats, a single dose of corticosteroid (methylprednisolone) did not change the acute response of injured rotator cuff tendons, as measured by collagen expression ratios, indicating that it does not negatively affect the healing process after injury.

Interestingly, the corticosteroid treatment alone (without injury) caused a significant increase in the type-III to type-I collagen expression ratio, suggesting that corticosteroids can mimic an injury response in healthy tendons, but this effect is temporary and returns to baseline within three weeks.

In a study of 62 patients with chronic elbow tendinopathy, a medicated plaster containing betamethasone valerate significantly reduced pain compared to a placebo, with a mean reduction in pain score of -39.35 mm for the 12-hour application and -36.91 mm for the 24-hour application.

The BMV plaster was found to be safe and well tolerated, with similar local tolerability to the placebo and few treatment-related adverse events.

In a study of 80 patients undergoing arthroscopic rotator cuff repair, a subacromial injection of sodium hyaluronate/carboxymethylated cellulose (HA/CMC) showed a trend towards faster recovery of shoulder forward flexion at 2 weeks post-surgery, although this was not statistically significant.

The injection did not lead to any complications or adverse effects on rotator cuff healing, suggesting it is a safe option, but further research is needed to confirm its effectiveness in reducing postoperative shoulder stiffness.

In a study of 230 patients with subacromial impingement, those who received three or more corticosteroid injections showed no significant increase in the incidence of rotator cuff tears compared to those who received fewer than three injections.

The findings suggest that repeated corticosteroid injections into the subacromial space do not contribute to the risk of rotator cuff damage, indicating that their use can be considered safe in this context.

Corticosteroids (CS) significantly decreased cell proliferation in human tendon fibroblasts and led to apoptosis of tendon fibroblasts in rats, indicating a negative impact on tendon healing.

In contrast, hyaluronic acid (HA) did not cause cell death and was associated with better biomechanical strength in treated tendons compared to those treated with CS, suggesting HA may be a safer option for promoting tendon healing.

In a study involving 25 female Sprague-Dawley rats, repeated subacromial corticosteroid injections (methylprednisolone and betamethasone) led to harmful changes in the rotator cuff tendons, including abnormal softness and fragmentation of collagen bundles.

The findings suggest that frequent steroid injections for conditions like subacromial impingement syndrome may be detrimental, as 43% of rats treated with methylprednisolone and 71% with betamethasone showed significant structural damage to their tendons.

Corticosteroid injections into the subacromial-subdeltoid bursa significantly reduced pain in patients with chronic subacromial bursitis compared to both hyaluronic acid and normal saline, with a notable difference in pain scores at eight weeks.

Hyaluronic acid injections showed only marginal improvement over normal saline, indicating that corticosteroids are the more effective treatment option for this condition.

Corticosteroid injections, commonly used in nonoperative treatment for rotator cuff conditions, may negatively impact tissue quality, which could affect surgical outcomes.

The effectiveness of steroid injections as a treatment option is not strongly supported by evidence, and factors like chronicity of the tear and tobacco use also play significant roles in the success of rotator cuff repairs.
