Clinical trial NCT02246530
Conditions: Partial Tear of Rotator Cuff Tendinopathy of Rotator Cuff
Sponsor: University of Alabama at Birmingham
Start date: 2014-07-01; Completion date: 2021-03-01
Enrollment: 11 participants; Allocation: RANDOMIZED; Intervention model: SINGLE_GROUP

Brief summary:
The goal of this project is to identify an effective and conservative approach to treating partial thickness rotator cuff tears (PTRCT) that otherwise would end with a surgical correction needed.

Detailed description:
Based off literature and clinical practice, the majority of rotator cuff tears continue to progress to surgical correction despite conservative measures. These include physical therapy, medication management and minimally invasive procedures such as subacromial bursa injections and intra-articular injections with steroids. Recently a popular treatment of common musculoskeletal injuries (including tendinopathies) has emerged throughout the US and has been utilized worldwide for many years with good empiric evidence known as Platelet-Rich Plasma (PRP) injections. In partnership with UAB Orthopedics and Radiology, the UAB Department of Physical Medicine and Rehabilitation aims to compare PRP to corticosteroid injections for patients with partial rotator cuff tears or tendinopathy. Outcome measures are ultrasound imaging, pain and disability over the course of 6 months.

Arms: arm 1: Treatment - PRP injection arm 2: Current standard of care for treatment of resistant partial thickness rotator cuff tears
Interventions: intervention 1: PRP injection into PTRCT intervention 2: Subacromial steroid bursal injection
Intervention descriptions: intervention 1: Day of procedure, 60 cc blood draw will be taken for processing and isolation of PRP. PRP sample will be injected peri-tendinous / intra-tendinous area at location of the PTRCT under ultrasound guidance to ensure accurate placement at site of injury.

PRP is an autologous blood product that is being re-injected into the same patient and is considered a non-invasive interventional procedure. PRP is classified as a procedure and not a drug. intervention 2: Combination steroid (Celestone) and anesthetic drug (Lidocaine) will be injected into the patient's subacromial bursa via needle guidance of ultrasound

INTRODUCTION 
 
2.1 
STUDY RATIONALE  
 
This research study will test a medical procedure’s ability to assist in the healing process of Partial-
Thickness Rotator Cuff Tears (PTRCT). The procedure uses an isolation of growth factors and platelets 
called “Platelet-Rich Plasma” (PRP) isolated from your own blood and re-injected to the site of damage, 
under ultrasound guidance. This procedure is currently being done across the United States and world-
wide and has been demonstrated as a safe procedure. Limited research on this procedure has been 
done in the United States involving the PTRCT. This is an investigational research study on the 
procedure’s effectiveness. Currently standard of care at UAB is a stepwise progression. First physical 
therapy is prescribed anywhere from 2-6 weeks for 1-2 times per week. If physical therapy fails to 
improve symptoms, then shoulder injections of a combination of steroids and numbing agents are used. 
If this fails, then surgical procedures are considered. People who enter into the study will be randomly 
picked (like the flip of a coin) by a computer into 1 of 2 groups: 1) injected with PRP produced from their 
own blood or 2) combination steroid / anesthetic (current standard of care treatment). This study will 
enroll 20 participants from the Birmingham area with goal of 10 participants in each group. 
 
2.2 
BACKGROUND  
 
Rotator cuff pathology and specifically Partial-Thickness Rotator Cuff Tears (PTRCT) remain a leading 
cause of shoulder pain in adult patients. Rotator cuff disease is the most common cause of disability 
related to shoulder pain. Typically tears develop in the supraspinatus tendon and progress gradually 
because of intrinsic degenerative demands. An association of cuff tears with increasing age has also 
been demonstrated, with 50% of individuals in their 80s having either symptomatic and/or 
asymptomatic RCT. There does seem to be a correlation between the presence of pain and progression 
of tear size indicating that the symptom of pain should warrant close monitoring. 
 
2.3 
RISK/BENEFIT ASSESSMENT   
 
2.3.1 KNOWN POTENTIAL RISKS  
 
The most common risks include pain at the injection site, infection at the injection site, no relief of 
symptoms, worsening of symptoms, deep vein thrombosis, damage to neurovascular structures, 
bruising, allergic reaction, local toxicity, scar tissue formation, or intravascular infection. 
 
2.3.2 KNOWN POTENTIAL BENEFITS  
 
You may or may not benefit from the procedure. Benefits may include reduction of pain and improved 
function and strength.

3 
Subjects were randomized into one of two groups (treatment group vs. control group). During the first 
in-office visit, we obtained an initial assessment and a diagnostic ultrasound with a radiologist. If the 
subject was in the treatment group, we collected about 10-12 mL of autologous blood from the subject. 
We used this blood to isolate the PRP and inject it to the treatment area. If the subject was in the 
control group, an injection combination of steroid and anesthetic (1ml betamethasone + 4.5 ml 
bupivacaine + 4.5 ml lidocaine) was injected to the treatment area. The subject completed three phone 
surveys at 3 weeks, 6 weeks, and 6 months. Each subject also completed repeat ultrasound of the 
shoulder at a visit at 6 months post procedure. 
 
3.2 
END OF STUDY DEFINITION 
 
This study was terminated prematurely secondary to lack of successful largely secondary to the COVID 
pandemic.

5.1.1 STUDY INTERVENTION DESCRIPTION 
 
Experimental Group 
  Withdraw 10-12 mL of blood from your arm. 
  Process blood to isolate the PRP. 
  Skin will be cleaned to sterilize the surface. 
  Ultrasound machine with sterile gel will be used to visualize injection target. 
  Inject the PRP into the targeted area for the actual treatment. 
 
Control Group 
  Skin will be cleaned to sterilize the surface. 
  Ultrasound machine with sterile gel will be used to visualize injection target. 
  Inject combination (steroid and anesthetic) 1ml betamethasone + 4.5ml bupivacaine + 4.5ml lidocaine. 
 
 
5.2 
MEASURES TO MINIMIZE BIAS: RANDOMIZATION 
 
The study was originally intended for 20 subjects. Subjects number 1 through number 20 were 
randomized via a randomization calculator prior to starting into the treatment or control groups. As 
enrollment began, subjects were numbered in the study on a rolling basis an divided into their 
respective group based on the predetermined randomization.  
 
5.3 
STUDY INTERVENTION COMPLIANCE 
 
Overall, there was poor compliance in this study. We had 14 patients enroll originally. Three patients 
had a negative diagnostic ultrasound thus were excluded from the study. Two patients were randomized 
into the Control Group, and both completed all study requirements. Nine patients were randomized into 
the Treatment group; of these 9 patients, 4 did not complete all follow up questioners and 2 did not 
complete the 6 month follow up ultrasound.  
 
5.4 
CONCOMITANT THERAPY 
 
Subjects were asked to avoid use of NSAIDs, including Advil, Aleve, Ibuprofen, Naproxen, Voltaren, 
Aspirin, for six weeks after the injection, as it will interfere with the beneficial effects of the PRP 
treatment. Tylenol (acetaminophen), ice and heat were allowed as needed for pain relief. 
Activity: Normal day to day activity was permitted. Subjects were asked to refrain from any significant 
activity involving the injected site for first 3 days after procedure. Gradually increase activity over the 
next 6-12 weeks as tolerated.

6.2 
SUBJECT DISCONTINUATION/WITHDRAWAL FROM THE STUDY 
Subjects are free to withdraw from participation in the study at any time upon request. 
An investigator may discontinue or withdraw a subject from the study for the following reasons: 
 
• 
Significant study intervention non-compliance  
• 
If any clinical adverse event (AE), laboratory abnormality, or other medical condition or situation 
occurs such that continued participation in the study would not be in the best interest of the 
subject 
Subjects who sign the informed consent form and are randomized but do not receive the study 
intervention may be replaced.  Subjects who sign the informed consent form, and are randomized and 
receive the study intervention, and subsequently withdraw, or are withdrawn or discontinued from the 
study, will not be replaced. 
6.3 
LOST TO FOLLOW-UP 
A subject will be considered lost to follow-up if he or she fails to return for 2 scheduled visits and is 
unable to be contacted by the study site staff.  
 
The following actions must be taken if a subject fails to be available for a required study visit: 
• 
The site will attempt to contact the subject and reschedule the missed visit and counsel the 
subject on the importance of maintaining the assigned visit schedule and ascertain if the subject 
wishes to and/or should continue in the study. 
• 
Before a subject is deemed lost to follow-up, the investigator or designee will make every effort 
to regain contact with the subject (where possible, 3 telephone calls and, if necessary, a certified 
letter to the subject’s last known mailing address or local equivalent methods). These contact 
attempts should be documented in the subject’s medical record or study file.  
• 
Should the subject continue to be unreachable, he or she will be considered to have withdrawn 
from the study with a primary reason of lost to follow-up. 
 
 
7 
STUDY ASSESSMENTS AND PROCEDURES 
 
7.1 
STUDY ASSESSMENTS  
 
Subjects were required to complete 3 telephone interviews to repeat questionnaire (SPADI) at week 3, 
week 6 and 6 months. 
At 6 months after initial procedure subjects were schedule for repeat diagnostic MSK ultrasound which 
was the end of the study. 
 
7.2 
ADVERSE EVENTS AND SERIOUS ADVERSE EVENTS 
   
7.2.1 DEFINITION OF ADVERSE EVENTS (AE) 


PRP for PTRCT 
Version 1.0 
 
01 02 2022 
 
 
6 
Adverse event means any untoward medical occurrence associated with the use of an intervention in 
humans, whether or not considered intervention-related (21 CFR 312.32 (a)). 
 
7.2.2 DEFINITION OF SERIOUS ADVERSE EVENTS (SAE)  
An adverse event (AE) is considered “serious” if, in the view of either the investigator or sponsor, it 
results in any of the following outcomes: 
 
• 
Death 
• 
A life-threatening adverse event (of note, the term “life-threatening” refers to an event in which 
the subject was at risk of death at the time of the event, rather than to an event which 
hypothetically might have caused death if it were more severe) 
• 
inpatient hospitalization or prolongation of existing hospitalization 
• 
a persistent or significant incapacity or substantial disruption of the ability to conduct normal 
life functions 
• 
or a congenital anomaly/birth defect. 
 
Important medical events that may not result in death, be life-threatening, or require hospitalization 
may be considered serious when, based upon appropriate medical judgment, they may jeopardize the 
subject and may require medical or surgical intervention to prevent one of the outcomes listed in this 
definition. Examples of such medical events include allergic bronchospasm requiring intensive treatment 
in an emergency room or at home, blood dyscrasias or convulsions that do not result in inpatient 
hospitalization, or the development of drug dependency or drug abuse. 
 
7.2.3 CLASSIFICATION OF AN ADVERSE EVENT 
7.2.3.1 SEVERITY OF EVENT 
For adverse events (AEs), the following guidelines will be used to describe severity:  
 
• 
Mild – Events require minimal or no treatment and do not interfere with the subject’s daily 
activities.  
• 
Moderate – Events result in a low level of inconvenience or concern with the therapeutic 
measures. Moderate events may cause some interference with functioning. 
• 
Severe – Events interrupt a subject’s usual daily activity and may require systemic drug therapy 
or other treatment. Severe events are usually potentially life-threatening or incapacitating.  Of 
note, the term “severe” does not necessarily equate to “serious.” 
 
7.2.3.2 RELATIONSHIP TO STUDY INTERVENTION 
All adverse events (AEs) must have their relationship to study intervention assessed by the clinician who 
examines and evaluates the subject based on temporal relationship and his/her clinical judgment. The 
degree of certainty about causality will be graded using the categories below. In a clinical trial, the study 
product must always be suspect.  
 
• 
Related – The AE is known to occur with the study intervention, there is a reasonable possibility 
that the study intervention caused the AE, or there is a temporal relationship between the study 
intervention and event. Reasonable possibility means that there is evidence to suggest a causal 
relationship between the study intervention and the AE. 


PRP for PTRCT 
Version 1.0 
 
01 02 2022 
 
 
7 
• 
Not Related – There is not a reasonable possibility that the administration of the study 
intervention caused the event, there is no temporal relationship between the study intervention 
and event onset, or an alternate etiology has been established. 
 
7.2.3.3 EXPECTEDNESS  
The Principal Investigator will be responsible for determining whether an adverse event (AE) is expected 
or unexpected.  An AE will be considered unexpected if the nature, severity, or frequency of the event is 
not consistent with the risk information previously described for the study intervention. 
7.2.4 TIME PERIOD AND FREQUENCY FOR EVENT ASSESSMENT AND FOLLOW-UP 
The occurrence of an adverse event (AE) or serious adverse event (SAE) may come to the attention of 
study personnel during study visits and interviews of a study subject presenting for medical care, or 
upon review by a study monitor. 
 
All AEs including local and systemic reactions not meeting the criteria for SAEs will be captured on the 
appropriate case report form (CRF). Information to be collected includes event description, time of 
onset, clinician’s assessment of severity, relationship to study product (assessed only by those with the 
training and authority to make a diagnosis), and time of resolution/stabilization of the event. All AEs 
occurring while on study must be documented appropriately regardless of relationship. All AEs will be 
followed to adequate resolution. 
 
Any medical condition that is present at the time that the subject is screened will be considered as 
baseline and not reported as an AE. However, if the study subject’s condition deteriorates at any time 
during the study, it will be recorded as an AE.  
 
Changes in the severity of an AE will be documented to allow an assessment of the duration of the event 
at each level of severity to be performed. AEs characterized as intermittent require documentation of 
onset and duration of each episode. 
 
The Study Coordinator will record all reportable events with start dates occurring any time after 
informed consent is obtained until 7 (for non-serious AEs) or 30 days (for SAEs) after the last day of 
study participation.  At each study visit, the Study Coordinator will inquire about the occurrence of 
AE/SAEs since the last visit.  Events will be followed for outcome information until resolution or 
stabilization. 
 
7.2.5 ADVERSE AND SERIOUS ADVERSE EVENT REPORTING  
All serious adverse events must be reported to the IRB according to regulatory requirements. The 
Principal Investigator will immediately report to the sponsor any serious adverse event, whether or not 
considered study intervention related, including those listed in the protocol or package insert and must 
include an assessment of whether there is a reasonable possibility that the study intervention caused 
the event. Study endpoints that are serious adverse events (e.g., all-cause mortality) must be reported 
in accordance with the protocol unless there is evidence suggesting a causal relationship between the 
study intervention and the event (e.g., death from anaphylaxis). In that case, the investigator must 
immediately report the event to the sponsor. 
 


PRP for PTRCT 
Version 1.0 
 
01 02 2022 
 
 
8 
All serious adverse events (SAEs) will be followed until satisfactory resolution or until the Principal 
Investigator deems the event to be chronic or the subject is stable. Other supporting documentation of 
the event may be requested and should be provided as soon as possible. 
 
7.3 
UNANTICIPATED PROBLEMS 
 
7.3.1 DEFINITION OF UNANTICIPATED PROBLEMS (UP) 
The Office for Human Research Protections (OHRP) considers unanticipated problems involving risks to 
subjects or others to include, in general, any incident, experience, or outcome that meets all of the 
following criteria: 
 
• 
Unexpected in terms of nature, severity, or frequency given (a) the research procedures that are 
described in the protocol-related documents, such as the Institutional Review Board (IRB)-
approved research protocol and informed consent document; and (b) the characteristics of the 
subject population being studied 
• 
Related or possibly related to participation in the research (“possibly related” means there is a 
reasonable possibility that the incident, experience, or outcome may have been caused by the 
procedures involved in the research); and 
• 
Suggests that the research places subjects or others at a greater risk of harm (including physical, 
psychological, economic, or social harm) than was previously known or recognized. 
 
7.3.2  UNANTICIPATED PROBLEM REPORTING  
The investigator will report unanticipated problems (UPs) to the reviewing Institutional Review Board 
(IRB). The UP report will include the following information: 
 
• 
Protocol identifying information: protocol title and number, PI’s name, and the IRB project 
number; 
• 
A detailed description of the event, incident, experience, or outcome;  
• 
An explanation of the basis for determining that the event, incident, experience, or outcome 
represents an UP;  
• 
A description of any changes to the protocol or other corrective actions that have been taken or 
are proposed in response to the UP. 
 
To satisfy the requirement for prompt reporting, UPs will be reported using the following timeline:   
 
• 
UPs that are serious adverse events (SAEs) will be reported to the IRB within 10 working days of 
the investigator becoming aware of the event.  
• 
Any other UP will be reported to the IRB within 10 working days of the investigator becoming 
aware of the problem.

STATISTICAL CONSIDERATIONS  
 
A statistical analysis was not completed for this study. This was due to the fact that this study was 
terminated early with lack of comprehensive results to analyze. At termination, we had 11 subjects in 
total enrolled: 9 treatment group subjects and 2 control group subjects. Five of the 11 subjects in this 


PRP for PTRCT 
Version 1.0 
 
01 02 2022 
 
 
9 
study had incomplete data, being lost to follow up at some point during the 6-month observation period 
for various reasons. Due to the small sample size, early termination of the study, and lack of full data 
sets for our enrolled participants, there was inconclusive data to run statistical analysis.

SUPPORTING DOCUMENTATION AND OPERATIONAL CONSIDERATIONS 
 
9.1 
REGULATORY, ETHICAL, AND STUDY OVERSIGHT CONSIDERATIONS 
 
9.1.1 INFORMED CONSENT PROCESS 
 
9.1.1.1 CONSENT/ASSENT AND OTHER INFORMATIONAL DOCUMENTS PROVIDED TO SUBJECTS 
Consent forms describing in detail the study intervention, study procedures, and risks are given to the 
subject and written documentation of informed consent is required prior to conducting study screening 
procedures. A separate screening consent form will not be used. 
 
9.1.1.2 CONSENT PROCEDURES AND DOCUMENTATION 
Informed consent is a process that is initiated prior to the individual’s agreeing to participate in the 
study and continues throughout the individual’s study participation. Consent forms will be Institutional 
Review Board (IRB)-approved and the subject will be asked to read and review the document. The 
investigator will explain the research study to the subject and answer any questions that may arise. A 
verbal explanation will be provided in terms suited to the subject’s comprehension of the purposes, 
procedures, and potential risks of the study and of their rights as research subjects.  Subjects will have 
the opportunity to carefully review the written consent form and ask questions prior to signing. The 
subjects should have the opportunity to discuss the study with their family or surrogates or think about 
it prior to agreeing to participate. The subject will sign the informed consent document prior to any 
procedures being done specifically for the study. Subjects must be informed that participation is 
voluntary and that they may withdraw from the study at any time, without prejudice. A copy of the 
informed consent document will be given to the subjects for their records. The informed consent 
process will be conducted and documented in the source document (including the date), and the form 
signed, before the subject undergoes any study-specific procedures. The rights and welfare of the 
subjects will be protected by emphasizing to them that the quality of their medical care will not be 
adversely affected if they decline to participate in this study. 
9.1.2 STUDY DISCONTINUATION AND CLOSURE 
This study may be temporarily suspended or prematurely terminated if there is sufficient reasonable 
cause.  Written notification, documenting the reason for study suspension or termination, will be 
provided by the suspending or terminating party to regulatory authorities.  If the study is prematurely 
terminated or suspended, the Principal Investigator (PI) will promptly inform study subjects and the 
Institutional Review Board (IRB), will provide the reason(s) for the termination or suspension.  Study 
subjects will be contacted, as applicable, and be informed of changes to study visit schedule. 
  
Circumstances that may warrant termination or suspension include, but are not limited to: 
• 
Determination of unexpected, significant, or unacceptable risk to subjects 
• 
Demonstration of efficacy that would warrant stopping

• 
Insufficient compliance to protocol requirements 
• 
Data that are not sufficiently complete and/or evaluable 
• 
Determination that the primary endpoint has been met 
• 
Determination of futility 
 
Study may resume once concerns about safety, protocol compliance, and data quality are addressed, 
and satisfy the IRB. 
 
9.1.3 CONFIDENTIALITY AND PRIVACY  
Subject confidentiality and privacy is strictly held in trust by the participating investigators and their 
staff. Therefore, the study protocol, documentation, data, and all other information generated will be 
held in strict confidence. No information concerning the study or the data will be released to any 
unauthorized third party without prior written approval of the Principal Investigator.  
 
All research activities will be conducted in as private a setting as possible. 
 
Representatives of the Institutional Review Board (IRB) may inspect all documents and records required 
to be maintained by the investigator, including but not limited to, medical records (office, clinic, or 
hospital) and pharmacy records for the subjects in this study. The clinical study site will permit access to 
such records. 
 
The study subject’s contact information will be securely stored at each clinical site for internal use 
during the study. At the end of the study, all records will continue to be kept in a secure location for as 
long a period as dictated by the reviewing IRB and/or Institutional policies. 
 
Study subject research data, which is for purposes of statistical analysis and scientific reporting, will be 
stored at the UAB Department of Otolaryngology research office. This will not include the subject’s 
contact or identifying information. Rather, individual subjects and their research data will be identified 
by a unique study identification number. The study data entry and study management systems used by 
research staff will be secured and password protected.  
 
9.1.4 QUALITY ASSURANCE AND QUALITY CONTROL 
The site will perform internal quality management of study conduct, data collection, documentation and 
completion.  Quality control (QC) procedures will be completed by the Data Manager during data entry 
into the appropriate CRF. Any missing data or data anomalies will be communicated to the Study 
Coordinator for clarification/resolution. 
 
Following written Standard Operating Procedures (SOPs), the monitors will verify that the clinical trial is 
conducted and data are generated are collected, documented (recorded), and reported in compliance 
with the protocol, International Conference on Harmonisation Good Clinical Practice (ICH GCP), and 
applicable regulatory requirements.  
 
The site will provide direct access to all trial related sites, source data/documents, and reports for the 
purpose of monitoring and inspection by local and regulatory authorities. 
 
9.1.5 DATA HANDLING AND RECORD KEEPING

9.1.5.1 DATA COLLECTION AND MANAGEMENT RESPONSIBILITIES  
Data collection is the responsibility of the clinical trial staff at the site under the supervision of the 
Principal Investigator. The Principal Investigator is responsible for ensuring the accuracy, completeness, 
legibility, and timeliness of the data reported. 
 
All source documents should be completed in a neat, legible manner to ensure accurate interpretation 
of data.   
 
Hard copies of source document worksheets will be used for recording data for each subject enrolled in 
the study.  Data recorded in the case report form (CRF) derived from source documents should be 
consistent with the data recorded on the source documents.  
 
9.1.5.2 STUDY RECORDS RETENTION  
Study documents should be retained for a minimum of 3 years after the completion of the study. These 
documents should be retained for a longer period, however, if required by local regulations.  
 
9.1.6 PROTOCOL DEVIATIONS  
A protocol deviation is any noncompliance with the clinical trial protocol requirements. The 
noncompliance may be either on the part of the subject, the investigator, or the study site staff. As a 
result of deviations, corrective actions are to be developed by the site and implemented promptly.  
 
These practices are consistent with ICH GCP:  
• 
4.5 Compliance with Protocol, sections 4.5.1, 4.5.2, and 4.5.3  
• 
5.1 Quality Assurance and Quality Control, section 5.1.1  
• 
5.20 Noncompliance, sections 5.20.1, and 5.20.2.  
 
It is the responsibility of the Principal Investigator to use continuous vigilance to identify and report 
deviations within 10 working days of identification of the protocol deviation.  Protocol deviations must 
be sent to the reviewing Institutional Review Board (IRB) per their policies. The Principal Investigator is 
responsible for knowing and adhering to the reviewing IRB requirements.  
 
9.1.7 CONFLICT OF INTEREST POLICY 
The independence of this study from any actual or perceived influence, such as by the pharmaceutical 
industry, is critical.  Therefore, any actual conflict of interest of persons who have a role in the design, 
conduct, analysis, publication, or any aspect of this trial will be disclosed and managed. Furthermore, 
persons who have a perceived conflict of interest will be required to have such conflicts managed in a 
way that is appropriate to their participation in the design and conduct of this trial.
