Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this research study is to determine if the effectiveness of a single injection of CTM Boost in the treatment of patients with rotator cuff tendinopathy (RCT) is as effective as a single injection of platelet rich plasma (PRP) in reducing the symptoms of RCT.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Rotator cuff tendinopathy (RCT), is a chronic degenerative process which causes both shoulder pain as well as limited range of motion. It is currently estimated that approximately 5% of RCT is being managed surgically, which highlights the importance of effective non-operative treatment strategies.

The advent of platelet rich plasma (PRP), a sample of blood drawn from a patient and concentrated to include mainly platelets and potent inflammatory mediators which promote healing, has shown promise as another treatment modality when injected at the site of tendon damage. Placenta-derived decellularized connective tissue matrix (CTM) may represent an alternative therapy for RCT. Placenta-derived biologics can be administered as an injection and have been shown to promote tenocyte proliferation and to reduce inflammation in vitro, thus potentially accelerating and enhancing tendon healing.

This study is being conducted to determine if injection of CTM Boost is non-inferior to injection of PRP with regard to pain and function at Month 6 post-injection in patients with rotator cuff tendinopathy.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Two-arm, double-blinded, randomized controlled trial with the primary objective of evaluating non-inferiority of CTM (study intervention arm) to PRP (active comparator arm) for rotator cuff tendinopathy pain and function.
Primary Study Purpose

TREATMENT

Blinding Strategy

TRIPLE

Participants Caregivers Investigators
Participants will be randomized to one of the two arms by unblinded research personnel. Unblinded key study personnel will prepare the injection of either CTM Boost or PRP using an opaque sleeve to obscure the contents of the injection. Both patients and investigators will be blinded to treatment arm.

Each participant will undergo an antecubital blood draw of 60 milliliers (mL). Staff will wait about 20 minutes after the blood draw to injection time. This will be done to maintain blinding due to the 17 minutes it takes for the system to produce PRP. For patients in the CTM arm, the PRP blood draw serves as a placebo draw and the specimen will be discarded afterwards, in order to maintain blinding

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

CTM Treatment

2.0 cc (cubic centimeter) dose injection of CTM Boost will be administered by injection directly into the rotator cuff using a 20 gauge needle.

Group Type EXPERIMENTAL

CTM Boost

Intervention Type BIOLOGICAL

Connective Tissue Matrix (CTM) Boost is a decellularized Human Cellular and Tissue Based Allograft derived from placental connective tissue. It is considered a minimally-manipulated biologic by the FDA and is marketed as an allograft for repairing connective tissue. It is administered via injection.

PRP Treatment

Each participant randomized to this arm will receive a single injection of Platelet Rich Plasma (PRP).

Group Type ACTIVE_COMPARATOR

PRP

Intervention Type BIOLOGICAL

PRP is derived by a sample of blood drawn from a patient and concentrated to include mainly platelets and potent inflammatory mediators which promote healing.

At baseline, a blood draw of 60 milliliter (mL) will be obtained and concentrated in an Angel System to yield 5 cc of PRP and a supra-physiological concentration of white blood cells. All injections will be done under ultrasound guidance. A two-part injection process will be used. An advancing 20 gauge 1.5-inch needle first placed 3 mL of 1% xylocaine proximal to the tendinopathic area or tear. The needle will then be re-inserted at the proximal aspect of the lesion and slowly removed while infiltrating of 5 mL of PRP without activation with Calcium Chloride/thrombin at the lesion and surrounding tendon.
