About this trial

Rotator cuff (RC) injuries are particularly prevalent, difficult to repair, and attachment between the bone and tendon is notoriously difficult to achieve. The most common method and current standard of care (SOC) for reattaching connective tissues (e.g., ligaments, tendons) to bone typically involves suture anchor-based techniques, but this is fraught with problems. More specifically, re-tearing of the connective tissue after this procedure occurs in 30-60% of cases, and can be even higher in patients who engage in smoking, have a diagnosis of diabetes, etc. To address these clinical challenges, Sparta Biopharma Inc. (Sparta) developed a unique technology, called BioEnthesis, to improve the connection between the tendon and bone. Pre-clinical in vivo studies demonstrated that the biphasic bovine cancellous matrix regenerated at the bone-soft tissue interface-thereby leading to high structural integrity and will likely lead to reduced re-tear rates over time. The investigators hypothesize that patients in this interventional cohort will experience enhanced mobility, reduced pain, and less re-tears after RC procedures versus a standard suture anchor-based repair.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

DEERS-eligible

Adults, between the ages of 18-65 (inclusive)

Presenting with a rotator cuff tear that is reparable surgically (a reparable tear is defined as tear of the RC where it is possible to bring the retracted tendon edge back to the greater tuberosity of the humerus under minimal tension)

Ability to undergo surgery to repair rotator cuff tear

Disqualifiers

Previous shoulder surgery (excluding acromioplasty or diagnostic arthroscopy)

Inability to receive an MRI

Current (within the past 6 months) tobacco user

Unwilling to remain tobacco free for the duration of the study

Trial outcomes

Primary outcomes

1

Rates of re-tear

Re-tear rates following rotator cuff repair using BioEnthesis versus standard of care. Assessed with (1) 12-month follow-up shoulder MRI and assigning Sugaya Classification, and (2) adverse events evaluation at each follow-up timepoint

Time frame
Post-operation at 3-months, 6-months, and 12-months

Secondary outcomes

1

Change in the Visual Analogue Scale (VAS) from before surgery to after surgery

A tool used to help a person rate the intensity of certain sensations and feelings, such as pain. The visual analog scale for pain is a straight line with one end meaning no pain and the other end meaning the worst pain imaginable.

Time frame
Pre-operation (baseline) and then post-operation at 3-months, 6-months, and 12-months
2

Change in the return to activities of daily living (ADL) from before surgery to after surgery

A survey asking patients if and when patients have returned to various activities of daily living, such as work, driving, physical/recreational activities.

Time frame
Pre-operation (baseline) and then post-operation at 3-months, 6-months, and 12-months
3

Change in the Concomitant medications (ConMeds) from before surgery to after surgery

A survey asking patients to indicate any medications they are taking at the time of the survey (e.g., Acetaminophen, opioids, NSAIDs, etc.)

Time frame
Pre-operation (baseline) and then post-operation at 3-months, 6-months, and 12-months
4

Change in the Single Assessment Numeric Evaluation (SANE) from before surgery to after surgery

The SANE score is a validated patient reported outcome measure. It is a single question score that asks, "how would you rate your condition today as a percentage of normal (0% to 100% scale with 100% being normal)?" The SANE score is collected as standard of care.

Time frame
Pre-operation (baseline) and then post-operation at 6-months, and 12-months
