Conditions: Anterior Cruciate Ligament Tear
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 6
Healthy volunteers: no

Brief summary:
Injury to the knee during sports participation often involves partial or full detachment of the anterior cruciate ligament (abbreviated as ACL). ACL tears cause pain, swelling and inflammation. While the swelling and inflammation usually goes away in time, individuals with ACL injuries may experience pain and notice knee instability (knee slipping, etc.). Often surgery can repair or replace the ACL within the joint, allowing individuals the ability to walk or run again pain free or participate in sports. Unfortunately, osteoarthritis of the knee, which also causes pain and swelling, can occur in that same knee 10-20 years later for reasons which are not well understood.

In this research study, the investigator hopes to reduce the initial pre-operative pain. The reduction of pain will allow for earlier movement of the knee joint and preparation for surgery. The investigator is interested to see if the use of Kineret does decrease the risk of developing arthritis in individuals with ACL injuries by treating them within 28 days after their injury.

Detailed description:
Kineret® was chosen because it is safe, well tolerated, and has been used to treat Rheumatoid Arthritis (RA) and post-surgical persistent knee effusions as well as knee stiffness. Although Kineret® is approved by the US Food and Drug Administration (FDA) for the treatment of RA and Neonatal-Onset Multisystem Inflammatory Disease, it is not currently approved by the FDA for use in treating ACL injury. Therefore, the use of Kineret® in this study is investigational.

The research procedures will be conducted at the University of Kentucky (UK) Medical Center. Participants will need to come to the UK Healthcare at Turfland located at 2195 Harrodsburg Road in Lexington, KY. Participants will be asked to come to this location seven times during the study. Each of those visits will take about 30 minutes. All exams and questionnaires will be administered during the otherwise necessary routine visits for any participant who has suffered an ACL tear. No additional visit is necessary. The total amount of time commitment for participation in this study is about 6 1/2 hours, over the next 2 years.

All participants with sports related ACL injuries enrolled in this study will be seen and may elect to undergo surgery, if necessary. Note: Surgery is not part of this protocol. Should participants be enrolled into the study and choose not to undergo ACL reconstruction (surgery), they will receive treatment according to this protocol.

Randomization: Once it has been determined that a participant qualifies for entry into the study, they will be randomized, like the flipping of coin into one of two treatment groups. Groups will receive knee injections with either Kineret® or a saline placebo. The saline placebo will contain no active medication. Both the participant and study doctor will not know what treatment group the participant is assigned to. However, in case of an emergency, the investigator will be able to find out what treatment group the participant has been assigned to.

* Group 1 will receive an injection of Anakinra (Kineret®, IL-1ra; 150mg) 1-28 days after ACL injury.
* Group 2 is the placebo group. Participants enrolled into this group will receive an injection of saline placebo at Visit 1.

X-rays: All participants would have undergone a routine clinical x-ray analysis at prior to Visit 1.

MRI: All participants will undergo initial MRI examination to confirm ACL injury at Visit 1 and subsequent MRIs will be performed at Visits 5 and 6.

Participants will undergo knee aspirations. During a knee aspiration, the investigator will remove fluid from the space around the knee using a needle and syringe. This is usually performed under a local anesthetic to either relieve swelling or to obtain fluid for analysis to diagnose a joint disorder and/or problem. Knee aspirations after ACL tear with a painful effusion are a common orthopaedic practice and standard of care in at the UK Medical Center. Thus they are not considered additional interventions with regard to this study unless the participant has no fluid in the knee.

At Visit 1: Participants may have a large effusion that requires aspiration. This would be done as part of the participants normal routine care.

At Visit 2: Should the participant elect to undergo ACL reconstruction surgery, they will undergo a study required knee aspiration. This will be performed for the purpose of the research.

At Visit 3: Should the participant elect to undergo ACL reconstruction surgery, and there is substantial post-operative fluid in the knee, the investigator may choose to aspirate the knee again. This would be done as part of the participants normal routine care.

After the aspiration procedure: Once home, it is important for the participant to keep the joint aspiration site clean and dry. The aspiration site may be tender or sore for a few days after the joint aspiration procedure. The investigator will instruct the participant on what pain reliever they may take.

Below is breakdown of what will happen at each study visit:

Visit 1 Screening (1-28 days following injury)

* Obtain informed consent and assent if necessary of potential subjects
* Review medical history to determine eligibility based on inclusion/exclusion criteria.
* MRI scheduled
* Review medications history to determine eligibility based on inclusion/exclusion criteria.
* Perform medical examinations and collect vital signs as needed to determine eligibility based on inclusion/exclusion criteria. All subjects must have a clinical exam that is consistent with an ACL tear.
* Height and weight will be recorded
* Collection of urine and blood for laboratory testing. Women of child bearing potential will be given a urine pregnancy test. Test must be negative in order to enroll into the study. Parents/Legal Guardians of minor females: Your child will have a pregnancy test to see if they are eligible to be in the study. The results will not be disclosed to anyone other than your child, except in the case of a risk to health or welfare.
* Subjects will have the following assessments: range of motion, knee instability (Lachman's test) and standardized weight bearing x-rays. At this time the subjects will also be asked to fill in a standard questionnaire covering the KOOS, IKDC, VR-12, and a Likert pain scale.

Following the review of above assessment results and a review of inclusion/exclusion criteria, subjects will be randomized into 1 of 2 treatment groups. Following randomization, subjects will undergo a knee aspiration and will receive their first dose study medication.

Visit 2 (day of surgery or 4-6 weeks post injury)

* Medical history
* Medication history
* ROM will be performed
* Knee aspiration (in the operating room under anesthesia. This will be omitted if you do not have surgery)
* KOOS, IKDC, VR-12, and a Likert pain scale administered prior to surgery
* Biomarkers (urine and serum) pre-operatively
* Review AEs and SAEs

Visit 3 (4-14 days after Visit 2)

* Knee aspiration (if clinical indicated)
* Biomarkers (urine and serum)
* Review for AE's and SAE's
* ROM will be performed

Visit 4 (6 months after Visit 2)

* Patient reported outcomes (PROs) administered
* KOOS, IKDC, VR-12, and a Likert pain scale administered
* ROM will be performed
* Review of AEs and SAEs

Visit 5 (12 months after Visit 2)

* MRI
* Patient reported outcomes (PROs) administered
* KOOS, IKDC, VR-12, and a Likert pain scale administered
* Biomarkers (serum and urine only)
* Review of AEs and SAEs
* ROM will be performed

Visit 6 (24 months after Visit 2)

* MRI
* Patient reported outcomes (PROs) administered
* KOOS, IKDC, VR-12, and a Likert pain scale administered
* Biomarkers (urine and serum)
* Review of AEs and SAEs
* ROM will be performed

The blood and fluid samples collected from the participants will NOT UNDERGO GENETIC TESTING. Samples will be analyzed and stored at a UK research laboratory. The will be tested for special markers of cartilage breakdown and will remain property of the University of Kentucky indefinitely or until they are completely used. The results from the analyzed samples are important only for research For this reason, these results will not be released to either the participant or their family.

Either the participant or their insurance company, Medicare or Medicaid will be responsible for the costs of all care and treatment they receive during this study that they would normally receive for their condition.

The University of Kentucky may not be allowed to bill an insurance company, Medicare or Medicaid for the medical procedures done strictly for research. These costs include the following:

* X-ray of the knee done at Visit 1
* Knee aspiration done at Visit 1 and Visit 3 (if necessary)

The University of Kentucky may not be allowed to bill your insurance company, Medicare or Medicaid for the medical procedures done strictly for research. The following will be provided at no cost to you: the injection of Kineret®, the second knee aspiration and potentially the third knee aspiration, questionnaires and three MRIs.

Participants will receive $150.00 for taking part in this study. They will receive $50.00 for each MRI completed. Payment will be in the form of a check which will be mailed approximately four to six weeks following the study visit. If the participant is a child the compensation will be mailed to the child.

Should a participant decide to withdraw from the study early they will be compensated for their time and travel.

PROTOCOL SUMMARY 
 
Title: 
 
A Prospective, Multicenter, Randomized, Triple-Blinded, Placebo-
Controlled study of IL-1RA Treatment in Patients with Acute ACL 
Tear and Painful Effusions 
Précis: 
This study aims to establish efficacy and timing of administration, to 
reduce post-injury pain, decrease inflammatory biomarkers in ACL 
injured patients undergoing ACL reconstruction and correlate 
function, patient reported outcomes and MRI findings at 1 years after 
ACL injury.  The study population will include 40 subjects, ages 14-
40 who will be randomized into 2 groups (20 subjects per group).   
Objectives: 
 
1. Test the efficacy of a treatment protocol using IL-1ra and knee 
arthrocentesis to alleviate inflammation related knee pain and 
improve patient-reported outcomes (PRO) following ACL rupture. 
2.  Determine if intra-articular IL-1ra therapy improves levels of a 
panel of inflammatory, meniscus and cartilage metabolism, and 
oxidative stress biomarkers as measured in synovial fluid, serum and 
urine from patients immediately after ACL injury (baseline, 2 weeks 
after injury and at 1 and 2 years after surgery). 
3.  Answer the question if MRI T1rho changes correlate with 
synovial biomarker levels and show predictive value for the overall 
subject patient outcome at 2 years. 
Endpoint 
Primary endpoint :    
Change in Patient reported outcomes as measured by KOOS-
Symptoms  
 
Secondary endpoints:  
KOOS QOL,  
KOOS-pain,  
KOOS-Sports/Rec,  
Biomarker levels in synovial fluid, serum and urine at time of surgery 
MRI T1rho changes at 2 years 
 
Study Stopping Criteria 
 
• Local intolerance of the administered Anakinra (Kineret®) or 
any sign of allergic response. 
• Development of signs and symptoms before the second time 
point preventing the second administration of the study drug. 
• Any patient reported and drug related SAE after the first or 
second administration of the study drug. 
• Diagnosis with any condition as outlined in the exclusion 
criteria during the course of the initial 2 weeks of study 
enrollment. 
Population: 
The study population will include up to 40 subjects within 28 days 
following of injury.  The study is open to male and female 
participants who are between the ages of 14 and 40, who have ACL 
tears. Participants will be enrolled at the University of Kentucky.

Description of Study 
Agent : 
IL-1ra (Kineret®, anakinra), supplied by Sobi Pharmaceuticals,  is a 
recombinant, nonglycosylated form of human interleukin-1 receptor 
antagonist (IL-1Ra).  Kineret® consists of 153 amino acids and has a 
molecular weight of 17.3 kilodaltons.  It is produced by recombinant 
DNA technology using an E coli bacterial expression system.  It is 
available as pre-filled syringes (100 mg in 0.67 mls) and is FDA 
approved for daily subcutaneous injection (100 mg/day) for treatment 
of rheumatoid arthritis (age > 10).  A total of 1.5 ml (150 mg) will be 
injected intra-articularly after synovial fluid aspiration 'to dryness' 
once between 1 and 28 days after ACL injury.

INTRODUCTION: BACKGROUND INFORMATION AND SCIENTIFIC 
RATIONALE  
 
2.1 
BACKGROUND INFORMATION  
 
A majority of individuals with partial or complete rupture of the anterior cruciate ligament 
(ACL) develop post-traumatic osteoarthritis (PTOA) 5-15 years after the initial injury. The long-
term consequences of PTOA include arthrofibrosis, pain, limited motion, and recurrent 
instability.  Because ACL injuries occur most often in younger individuals (average age 14-29 
years), pain and other debilitating symptoms occur most often during patients’ most productive 
years costing society upwards of 3.06 billion dollars annually [1]. Current surgical and non-
surgical treatment options for ACL injury, while relatively successful in restoring function and 
stability in the short term, do little or nothing to reduce or prevent the development of PTOA 
later in life.  
 
ACL rupture, with or without accompanying damage to nearby cartilage and bone, initiates a 
persistent cascade of inflammation and catabolic enzyme activity leading to OA of the knee 
joint.  We propose to disrupt the inflammation-driven cascade with recombinant Interleukin 1 
receptor antagonist (IL-1ra).   
 
IL-1ra was chosen because it is safe, well tolerated, and has been used to treat RA, juvenile 
inflammatory arthritis, and post-surgical persistent knee effusions as well as knee stiffness.[2-4.] 
Our own preliminary data suggests that IL-1ra reduces pain and improves function in patients 
with acute knee injury and arthrofibrosis.  IL-1ra binds to the Interleukin 1 receptor and 
nonproductively blocks the proinflammatory and cartilage catabolic activities of Interleukin 1 
alpha and beta.  IL-1ra levels in synovial fluid are initially higher following acute ACL injury 
but vanish rather quickly.  Subsequently, IL-1β levels rise slower in joint fluid after ACL rupture 
and remain high for longer periods of time.  IL-1ra has had mixed results in the treatment of 
established OA, possibly due to its short half-life in vivo.  However, if given shortly after the 
initial inciting event potentially initiating the development of OA, the effectiveness may be 
significantly higher.   
 
Unlike primary OA, which typically strikes older individuals and develops silently over the 
course of many years, post-traumatic OA is thought to begin at the moment of ACL injury in 
many individuals. Capitalizing on the expertise and experience of our collaborative team of 
investigators, we have chosen to seize this window of opportunity and provide the field with 
valuable new data regarding the importance of reduction of the initial inflammatory response to 
injury in acute ACL tears.  
 
It is estimated 250,000 injuries to the anterior cruciate ligament (ACL) occur each year (1). 
These injuries predominantly occur at young age (14-18 years) The incidence of these injuries in 
Kentucky alone is 108/100.000 (2), a number that is on par with the incidence of prostate cancer 
in men in the US (125/100.000) and higher than lung cancer in the US (79/100.000)(2) A high-
school soccer player has a knee injury risk of 1/50 player hours. In light of the fact that 
regardless of whether or not the ligament is reconstructed, at least 50% of these patients will 
develop post-traumatic osteoarthritis (PTOA) 10-20 years after injury. (3,4) The consequences of 
PTOA are debilitating, often resulting in participation restrictions and activity limitations that 
affect thousands of individuals each year. Currently the identification of treatment interventions, 
prevention strategies, or changes to current treatment algorithms to delay or deter the 
development of post-traumatic structural damage and subsequent PTOA development is limited 
as the precise mechanism and risk factors for the development of PTOA following ACL injury is 
unknown.

Early inflammation: Early inflammation leads to 
swelling, pain and pain related muscle shut down 
affecting recovery. Hemarthrosis and intra-articular 
pathogenic processes (e.g., down-regulation of 
proteoglycan synthesis and up-regulation of matrix 
metalloproteinases) initiate inflammation at the time 
of injury [5-7].  It is widely accepted that the 
balance between IL-1 and IL-1Ra are critical in the 
regulation of the pathological processes involved in 
joint tissue breakdown [8, 9]. IL-1 levels are 
elevated in patients with ACL rupture and correlate 
with severity of chondral damage in a study by 
Marks [10]. Additionally, chondroprotective 
cytokine levels are decreased with increasing 
severity of chondral damage [10]. The superficial 
cartilage layers have been shown to be more 
susceptible to IL-1 induced damage than deeper 
layers, in an in vitro study [11].  Moreover, synovial 
fluid levels of IL-1Ra are reported to decrease 
significantly after ACL injury, resulting in 
relatively unopposed activity of IL-1 [12]. This 
overall up-regulated catabolic state and inflammation leads to recurrent and painful effusions 
which significantly hinder early rehabilitation after injury but also post-operatively. Post-injury 
pain and intra-articular effusion are a major contributing factor to extensor mechanism shut 
down (quadriceps femoris) after injury or surgery which in itself is a significant risk factor for 
delayed recovery and posttraumatic OA development.  
 
Development of posttraumatic 
OA:  It is increasingly recognized 
that biochemical abnormalities of 
the joint precede radiographic 
abnormalities of primary or 
secondary OA by as much as 
decades. A growing body of 
evidence strongly suggests that 
the progression from ACL injury 
to osteoarthritis is multifactorial, 
involving the interplay between 
biomechanical disturbances and 
biochemical homeostasis of 
articular cartilage.  However, 
unlike primary OA, post-
traumatic secondary OA is 
initiated by intra-articular 
pathogenic processes with a 
known date of onset, namely the 
date of joint injury.  This makes 
it much more amenable to early intervention than primary OA whose onset is not clearly 
definable at this time.  For many years, however, it was believed that the biomechanically and 
anatomically correct reconstruction of the ACL would restore near normal joint kinematics. 
Biomechanically the knee joint can be restored to near normal knee kinematics using the latest 
Figure 1: Onset of early posttraumatic OA in a 24-year old 
patient 2 years after ACL reconstruction and partial medial 
meniscectomy. medial joint space narrowing and beginning 
subchondral sclerosis as well as mild squaring of the lateral 
femoral condyle can be seen in comparison to the opposite, 
uninjured side.  This patient ended up receiving a meniscal 
allograft transplant.

anatomic ACL reconstruction techniques. However, the considerable variation in response to 
surgical treatment even in well-controlled studies (2, 13-16) and  recent systematic reviews has 
suggested that reconstructive surgery of the ACL or meniscus fails to protect against OA 
development (2,4). When abnormal joint stressors and abnormal joint physiology occur together, 
the outcome is potentially even more severe (Figure 2, from Lohmander et al (2)).  This is 
illustrated by the fact that severe meniscal damage to the knee is more likely to cause eventual 
knee OA in patients with hand OA (evidence for a genetic predisposition to OA) compared with 
patients without hand OA (17). 
 
ACL Injury and Damage to Articular Cartilage: Chondrocytes (matrix secreting cells) are 
pressure sensitive, and cannot survive compressive forces above a certain threshold, even if the 
cartilage matrix itself is not injured directly.  This threshold may often be exceeded during ACL 
injuries. Without a sufficient number of chondrocytes to maintain a scaffold, the matrix 
eventually breaks down over time, causing pain and potential disability to the affected knee joint, 
often many years after ACL rupture.  While the injury mechanism may lead to direct cartilage 
damage, resulting biomechanical changes of knee function such as increased rotational 
instability, postsurgical changes or subtle loss of range of motion may lead to progressive 
breakdown of articular cartilage in the medial or lateral compartment and may appear as early as 
2 years after injury (18,19) as illustrated in Figure 1.  Indeed, Neuman et al. (20) reported knee 
cartilage glycosoaminoglycans changes within 2 years after ACL injury.  These changes are 
indicative of posttraumatic OA.  
 
Previous Clinical Research: The IL-1ra drug we are planning to use has been previously 
utilized in this patient population. The use of this drug is advantageous as it constitutes a 
meaningful repurposing of an already existing drug that has been shown to be safe in this patient 
population. 
 
Study 1: IL-1Ra decreased pain in an open label trial of arthrofibrosis:  Dr. Virginia Kraus, Co-
Investigator of this study, conducted two small clinical trials to test the beneficial effect of IL-
1ra, an inhibitor of IL-1 biological activity, in vivo.  Six patients who failed to meet entry criteria 
for a separate randomized trial because of age or time from injury to presentation, were entered 
into a small open label study in which they received 150 mg IL-1ra (anakinra, Amgen) intra-
articularly for the treatment of acute ACL injury (n=2), or chronic, recurrent, arthrofibrosis 
following surgical lysis of adhesions (n=4). All 4 arthrofibrosis patients reported improvement in 
knee pain, swelling, and joint motion.  Examination by the treating physician and by physician 
global assessment confirmed these results.  Five out of six patients reported clinically 
significant pain relief after the treatment.  There were no other complaints related to the 
drug and no evidence of significant adverse events in any patient. These results corroborate 
findings from animal studies and imply that adequate exposure to IL-1Ra early in the course of 
disease may potentially reduce pain and stiffness (21).  
 
Study 2: IL-1Ra decreased pain, and improved function, and lowered IL-1α levels in synovial 
fluid in a randomized pilot trial of ACL rupture:  In a second randomized trial, 11 patients with 
isolated ACL tears scheduled for later ACL surgery were treated with 150 mg (anakinra, Amgen; 
6 patients) or equal volume saline placebo (5 patients) intra-articularly within the first 30 days of 
acute knee injury. Mean age of participants was 24 + 4 (SD) years, (6 male, 5 female). 
Enrollment was limited to patients under 40 years of age to try to insure the lack of underlying 
pre-existing arthropathy. Patients were recruited a mean 15 + 7 (SD) days from injury (range 6-
27 days). Self-report of pain on a Likert scale 0-10 was recorded at baseline (0), 4 days, 14 days, 
and 28 days after treatment as well as on the day of surgery.  The standardized KOOS and IKDC 
questionnaires were also obtained.

Using the non-parametric Wilcoxon signed-rank sum test, significant differences (p<0.05) were 
observed in the anakinra treated group only: Pain was reduced in the anakinra treated group of 
patients by 23% after 4 days, improvement in Activities of Daily Living by 46%, and 
improvement in total KOOS by 24%; in contrast the placebo group improved by only 4%, 6% 
and 7% for these outcomes, respectively. This suggests a significan early effect in this patient 
population that is beneficial for the early rehab process prior to surgery(22). 
Synovial fluid IL-1α decreased over 1 month in response to a single IL-1Ra intra-articular 
injection in our pilot trial.   The change with treatment (Day 0 to Day 28) in synovial fluid 
IL-1α constituted the most intriguing and promising cytokine result from this pilot trial.  
IL-1α increased in all the placebo treated patients (n=4 pairs of samples available); whereas IL-
1α decreased in 4 or 5 of the anakinra treated patients (n=5 pairs of samples available)(21).   
 
Study 3: In order to prove that we have the 
ability to perform a high level (GCP) 
randomized clinical trial our group has 
performed a randomized clinical trial 
involving ACL patients in the same study 
design featuring identical enrollment 
(inclusion/exclusion) criteria as the one 
proposed in this contract (MOON-AAA 
Clinicaltrials.gov identifier: NCT01692756). 
In this multicenter early intervention trial 
testing the effect of Triamcinolone 
administration patients underwent knee joint 
aspirations, blood draws and urine collections 
at three time points prior to ACL surgery. 
PRO’s and clinical exams were performed at all time points prior to surgery and at 4 time points 
post-surgery up to 6 months post-surgery.   We have successfully enrolled 3-4 patients per month 
in the last 12 months actually exceeding the goal of 2 patients / month as initially estimated. The 
average time from injury to enrollment is 4.2 days with an average patient age of 18.6 years. No 
patients have been lost to follow-up. This trial has just completed enrollment and is in the 
process of data analysis (see table 1). This trial has been extraordinarily successful and was able 
to show that the initial chondrodegradatory response, as measured in synovial fluid can be 
modified intraarticularly with the administration of triamcinolone acetonide.  
 
Pediatric dosing -  Kineret®, was studied in a single randomized, blinded multi-center trial in 
86 patients with polyarticular course Juvenile Rheumatoid Arthritis (JRA; ages 2-17 years) 
receiving a dose of 1 mg/kg subcutaneously daily, up to a maximum dose of 100 mg. The 50 
patients who achieved a clinical response after a 12-week open-label run-in were randomized to 
Kineret® (25 patients) or placebo (25 patients), administered daily for an additional 16 weeks. 
 
A subset of these patients continued open-label treatment with Kineret® for up to 1 year in a 
companion extension study. An adverse event profile similar to that seen in adult RA patients 
was observed in these studies. Pediatric use of Kineret® was not recommended due to difficulty 
dosing the medication in smaller children requiring less than 100mg per dose and because  
efficacy could not be demonstrated due to low trial enrollment. No safety issues were seen. The 
dosing problem will not come to bear in our patient population as we only enroll children 14 
years and older. 
 
Trial Registration Number: NCT00339157. First prospective placebo controlled trial to evaluate 
the effectiveness of IL-1Ra for SJIA. Enrolled a total of 24 patients: mean (SD) age of 9.5 (5) 
years; female subjects entering the study were prepubescent, sexually inactive or required to use

effective contraception; 12 received 2 mg/kg sc daily for 1 year; 10 received placebo for one 
month then 2 mg/kg sc daily for 11 months. Max dose 100 mg qd. Anakinra treatment was 
effective in SJIA. They noted in the Discussion that: " PK data suggested that low-weight 
children might have benefited from a higher anakinra dosage." 
 
Safety: Between month 1 and month 12, six patients stopped treatment owing to an adverse event 
(n=2), lack of efficacy (n=2) or a disease flare (n=2). "One patient was diagnosed with 
inflammatory bowel disease, a complication reported in some patients initially diagnosed with JIA 
and treated with anti-TNF agents. An additional patient experienced a sudden rise in serum 
transaminases." Of note, patients were on concurrent corticosteroid therapy.39 
An open-label retrospective observational trial of 46 SJIA patients (median age 7.6 years) who 
received anakinra alone (n=10) or in combination with corticosteroids or remittive agents 
including methotrexate or cyclosporine.   
 
Dose: "The median starting dose of anakinra was 1.5 mg/kg/day (IQR 1.1–2.0 mg/kg/day; 
minimum 0.93 mg/kg/day, maximum 11.2 mg/kg/day), and subsequent dose escalation was 
required in 24% of patients. Patients requiring dose escalation received a median initial dose of 
1.3 mg/kg/day, compared with a median initial dose of 1.6 mg/kg/day in patients who did not (P 
not significant). Among 19 patients who started with a dose <1.5 mg/kg/day, 8 (42%) ultimately 
required a higher dose. One patient received anakinra twice daily. In most patients, therapy with 
anakinra could not be interrupted during the term of observation, but recurrent dose escalation 
(tachyphylaxis) was not observed. At the last follow-up visit, anakinra had been discontinued for 
inefficacy in 1 patient, for intolerance in 2, and because of remission in 3; 7 patients could be 
weaned to dosing every other day, although symptoms returned if the interval exceeded 48 
hours." Of note, the patient who received the highest dose of anakinra monotherapy (11.2 
mg/kg/day intravenously administered as 5.6 mg/kg every 12 hours) was being treated in 
intensive care for macrophage activation syndrome, a potentially life-threatening complication of 
SJIA. On this treatment: "She improved dramatically, but her response remained partial, and at 
the last follow-up visit, she was requiring anakinra at 2.3 mg/kg/day, abatacept, and monthly 
pulse corticosteroids."  
 
They concluded that "in general, improvement was rapid and striking." series, children older than 
7 years were more likely to exhibit a complete response to anakinra-based therapy than those 
ages 7 years and younger (75% versus 41%; P < 0.05). 
 
Safety: Five patients developed macrophage activating syndrome while on anakinra but this was 
believed to be due to SJIA and not anakinra. They stated: "the role of anakinra as a trigger for 
these 5 cases cannot be determined, in no case was permanent discontinuation necessary. 
Further, dose escalation often seemed to help control macrophage activation syndrome." 
Injection site reactions occurred in 44% of the 45 patients with evaluable data, leading to 
permanent discontinuation of drug in 1 patient and transient discontinuation in several others.  
 
There were 3 cases of serious infection. A 4-year-old child treated with anakinra at 1 mg/kg/day 
and 6 weeks of corticosteroids developed pneumococcal bacteremia at 2 months in the setting of 
parainfluenza infection. Anakinra was withheld for 1 week but was restarted because of rising 
levels of markers of inflammation. The patient remained well during an additional 6 months of 
observation. An 11-year-old child treated with anakinra (1.2 mg/kg/day) and high-dose oral 
corticosteroids developed an infection at a healed gastric feeding tube site. Anakinra was 
withheld for 2 weeks but was ultimately escalated to 1.9 mg/kg/day without further complication 
during 21 additional months of observation. A 3-yearold child receiving anakinra at 1.7 
mg/kg/day was admitted to the hospital for several days with pneumonia. No organism was 
cultured. Anakinra was restarted after discharge."

Other events included two episodes of bronchitis, 1 episode of eosinophilic hepatitis requiring 
discontinuation of anakinra, elevation of liver enzymes in 2 patients but anakinra could be 
continued, and mild neutropenia resolved on alternate day anakinra.40 
 
2.2 
RATIONALE  
 
We hypothesize that IL-1Ra administered intra-articularly during the early phase of acute ACL 
injury will provide symptomatic pain relief and decrease synovial fluid inflammatory and cartilage 
degradation markers.  ACL injury produces high levels of inflammatory mediators, including as 
IL-1, which mediate knee pain, perpetuate synovitis, and decrease functional recovery post injury 
and post-surgically. We have designed a clinical trial that specifically tests the ability of IL-1ra to 
alleviate pain following acute ACL injury and potentially changes patient reported outcomes at 2 
years.  
 
A total of 1 mL (150 mg) will be injected intra-articularly after synovial fluid aspiration 'to 
dryness' once at study entry 1-28 days after injury depending on time of presentation).  
 
Rational for including pediatric population 
 
The specific reason for enrolling the age group of children aged 14-18 is that these children have 
a musculoskeletal physiology like adults. 
• Their major growth plates are closed.  
• These patients may be treated surgically like adult patients with exactly the same surgical 
preparation, technique and rehabilitation as adults.  
• Children, particularly girls, between the ages of 14 and 18 have the highest statistical risk 
in any population of tearing their Anterior Cruciate Ligament. 25,45 
• Children in this age group are particularly vulnerable to the later development of 
osteoarthritis. Lohmander et al showed that young female soccer players in this age group 
developed symptomatic knee Osteoarthritis secondary to the ACL injury within 12 years 
of the injury.24  One could therefore argue that particularly children between completed 
puberty and 18 years of age have to be the patients requiring most of our concern 
regarding development of OA.  
• Furman et al. showed that early post-injury administration of IL-1Ra did not alter bone 
morphology or fracture healing after intra-articular fracture but significantly reduced 
cartilage degradation and inflammation.(46) 
• The value of intraarticular IL-1 blockade when given immediately after intraarticular 
injury has been demonstrated repeatedly. In a recent publication of Genemaras et al. the 
early administration of IL-1Ra could be shown to significantly down-regulate pro-
inflammatory Il1-β, TNF-α) and chondrodegredatory markers ( MMP-3,ADAMTS-
4,ADAMTS-5) immediately after non-destructive chondral impact injury to porcine 
articular cartilage(45). 
• Chevalier et al. showed in 2005 that intra-articular injection of anakinra in patients with 
knee OA is safe (47). It is important to realize that patients who have suffered an ACL 
injury are a substantial risk for chronic inflammatory changes leading to OA and, in fact, 
display these changes as early as 4 weeks after injury lasting for up to 5 years after ACL 
injury. (48,49) 
• A study performed by Brown et al. enrolled 8 patients with arthrofibrosis who were 
treated with intra-articular administration of 150mg of anakinra. Five of the eight 
enrolled patients were under the age of 24, 3 under the age of 21, and one patient aged 
15. None of these patients have shown any adverse events and all of them improved in 
their clinical outcomes. In addition the same group completed a study enrolling young 
patients (mean age 22+ 3) who suffered ACL injuries. This trial did also not show any

significant adverse events regarding safety of the drug administration. In contrary, they 
show improved post-injury pain scores.52 
 
In summary: We would like to argue that skeletally mature adolescents of ages 14-18 are 
musculoskeletally no different than their 19 year old and older counterparts and therefore 
deserve the same potential benefit that early treatment with IL-1Ra may offer older patients. We 
find of no data to indicate that intra-articular use of IL-1Ra would have a different effect in the 
14-18 year old over the 19-40 year old. There is no in-vitro or in-vivo data indicating a 
detrimental effect of Il-1Ra to articular cartilage or the knee joint as a whole in the dosages we 
are intending to use. We believe that the potential benefits of this trial for this patient population 
outweighs by far the uncertainty of unknown risks that may be associated specifically with being 
14-18 year old.  
 
The Federal Drug Administration has approved daily subcutaneous injections (100 mg) to 
patients with rheumatoid arthritis. Our goal is to sustain therapeutic levels of IL-1Ra in the joint 
during the early phase of acute joint injury.  We hypothesize that the post injury intra-articular 
administration of 150 mg IL-1Ra (Kineret®) will be well tolerated. 
 
By slowing the initial inflammatory process after injury and preventing the significant 
quadriceps muscle shutdown early, we aim to work towards this goal in this trial. We therefore 
conclude that given the limited risk of local side effects and the potential large benefit that this 
study would provide to the scientific community and its potential to significantly improve and

POTENTIAL RISKS AND BENEFITS  
 
2.3.1 KNOWN POTENTIAL RISKS  
 
Safety Precautions: Participants will be followed at regular intervals by their study doctor.  
During each visit participants will be evaluated for adverse events according to GCP guidelines 
and reported accordingly to IRB and FDA regulations. 
 
Risks associated with Kineret®:   
 
Reproductive Risks:  It is not known whether receiving Kineret® is harmful to an unborn child.  
Pregnancy after administration of Kineret® may involve risks to the mother, and her embryo or 
fetus.  Therefore, females who are capable of reproducing, must use effective contraceptive 
methods.  These methods must be used from the time of screening until Visit 2 during which  
any remaining medication will be washed out of the joint during the surgery.  If the participant 
does not elect to have surgery (visit 2) contraception methods will be documented until the end 
of the study. Examples of effective birth control are:  hormonal contraceptives (the pill, implant, 
transdermal patch, or injection), barrier methods (condom with spermicide, diaphragm with 
spermicide), IUD, or a male partner had a vasectomy. 
 
Lactating women:  It is not known whether this drug or its metabolites are excreted in human 
milk.  Because many drugs are excreted in human milk, caution should be exercised when 
Kineret® is administered to a nursing woman. 
 
Limitations, potential problems, and alternatives:  This study will allow for safety and 
efficacy assessment in patients with acute effusive knee injury.

• Dose:  Based on our work and the work of others, we believe 150 mg dosage is 
appropriate.  The goal of the study is to sustain levels of IL-1Ra long enough and a high 
enough concentrations during the critical, early time period to be effective.  For this 
reason, we have increased our dosage from a single injection (carried out in the 
preliminary study) to two injections. 
• Patient attrition:  Close and regular communication, particularly in the intensive first few 
months, will be provided to all subject participants.  Patients will be fully informed of the 
time commitments and need for a total of three arthrocenteses in order to recruit study 
subjects willing to participate in the full study.  Because arthrocentesis alone can be 
expected to benefit subjects, education regarding direct and indirect benefits of all aspects 
of the trial will be provided.  Subjects will also receive appropriate compensation for the 
time and travel. 
 
2.3.2 KNOWN POTENTIAL BENEFITS  
 
IL-1Ra, while potent, has had mixed results in the treatment of established OA, possibly due to 
its short half-life in vivo.  In this trial, we expect that an early intervention with IL-1Ra will 
effectively block the deleterious cascade of joint degradation events after joint injury.  We expect 
a significant effect of IL-1Ra on post-injury pain and concomitantly an increased improvement 
in early function.

OBJECTIVES AND PURPOSE 
 
Primary Objective:   To assess the efficacy of using IL-1ra and knee arthrocentesis to alleviate 
inflammation related knee pain and improve patient-reported outcomes (PRO) following ACL 
rupture. 
 
Secondary Objectives: 
 
1.   To determine if intra-articular IL-1ra therapy improves levels of a panel of inflammatory, 
meniscus and cartilage metabolism, and oxidative stress biomarkers as measured in synovial 
fluid, serum and urine from patients immediately after ACL injury (baseline, 2 weeks after injury 
and at 1 and 2 years after surgery). 
 
2.  To assess if MRI T1rho changes correlate with synovial biomarker levels and show predictive 
value for the overall subject patient outcome at 2 years

STUDY AGENT(S) AND CONTROL DESCRIPTION 
 
6.1.1 ACQUISITION 
 
Unblinded study drug will be shipped from the manufacturer Swedish Orphan Biovitrum (Sobi) 
directly to the site research pharmacist, after all required regulatory and legal documents have 
been received by the Sponsor. 
 
Replacement Procedures For Investigational Medicinal Product: Resupply shipments or 
replacement of study drug will be provided by Sobi after consultation with Dr. Stone. 
 
6.1.2 FORMULATION, APPEARANCE, PACKAGING, AND LABELING 
 
Formulation, Packaging and Labeling:  Kineret® is a recombinant, nonglycosylated form of 
human interleukin-1 receptor antagonist (IL-1Ra).  Kineret® consists of 153 amino acids and has 


EASI ACL 
Version 7.0 
 
3 March 2020 
20 
 
a molecular weight of 17.3 kilodaltons.  It is produced by recombinant DNA technology using an 
E coli bacterial expression system. 
 
Kineret is supplied in single use prefilled glass syringes with 29 gauge needles as a sterile, clear, 
colorless-to-white, preservative free solution for daily subcutaneous (SC) administration. The 
solution may contain trace amounts of small, translucent-to-white amorphous proteinaceous 
particles. Each prefilled glass syringe contains: 0.67 mL (100 mg) of anakinra in a solution (pH 
6.5) containing anhydrous citric acid (1.29 mg), disodium EDTA (0.12 mg), polysorbate 80 (0.70 
mg), and sodium chloride (5.48 mg) in Water for Injection, USP. 
 
The prefilled syringe contains an outer rigid plastic needle shield attached to an inner needle 
cover. The syringe or needle shield components are not made with natural rubber latex. 
 
Each syringe will have a label that will contain, at minimum, the protocol number, 
contents (written as “Kineret®”), applicable regulatory cautions, storage conditions, route 
of administration, and a space to write in the dispensing date, subject identification number and 
subject initials.  
 
6.1.3 PRODUCT STORAGE AND STABILITY 
 
The prepared syringes of Kineret or placebo will be stored in a separate, temperature controlled 
refrigerator at the investigative site.  
Kineret® should be stored in the refrigerator at 2° - 8° C (36° - 46°F).  DO NOT FREEZE OR 
SHAKE.  Protect from light. Kineret® should not be used after the expiration date unless 
otherwise notified by the Principal Investigator.   
 
The study drug will be sent to the designated research staff at the University of Kentucky.   
 
Once a subject is identified and consented, the study coordinator will utilize the syringe 
corresponding to the assigned patient ID to administer the study medication.  It has been shown 
by HPLC analyses, that Kineret is stable for at least 4 hours at ambient temperature and in light 
in 0.9%NaCl and in a plastic culture vial.38 
 
The refrigerator temperature must be monitored by site personnel on a regular basis and must be 
recorded on a temperature log sheet or recorded electronically.  In the event that the 
refrigerator’s temperature goes outside the 2° - 8° C (36° - 46°F) range, the Sponsor or designee 
should be contacted immediately at the telephone number provided in the protocol.  Only 
temperature excursions outside of the acceptable range, per the Sponsor’s procedures, are 
reported as protocol deviations. 
 
6.1.4 PREPARATION 
 
The study drug will be kept in a temperature controlled environment according to the 
manufacturer’s recommendations  
 
Under aseptic clean conditions, a total of 200 mg (1.34 mL) of Kineret® (concentration 
100mg/0.67ml) will be injected from 2 sterile original prefilled 100 mg syringes of Kineret into a 
sterile vial. A sterile graduated 5 mL syringe will then be used to draw 150 mg (1 mL) of Kineret 
for intraarticular injection into the knee. The medication must be transferred from the original 
prefilled Kineret syringes as the needles are intended for subcutaneous delivery and are not 
adequate for intra-articular knee injection. No dilution of the medication will be performed. 
 


EASI ACL 
Version 7.0

21 
 
For the placebo we will utilize 1 mL of 0.9%NACL sterile saline solution drawn up in the same 
type of syringe as for the Kineret administration in order to maintain double blinding of the study 
investigator and patients. 
The number of study syringes prepared by the designated research personnel or research 
pharmacist, per day, will depend on the number of potential enrollees or return patients requiring 
Kineret® injections that day. 
 
6.1.5 DOSING AND ADMINISTRATION 
Study treatment must only be dispensed by a pharmacist or other medically qualified staff.  
Study treatment is to be dispensed only to subjects enrolled in this study. 
 
Once a subject is identified and consented, the investigator will utilize the syringe corresponding 
to the assigned patient ID to administer the study medication.  It has been shown by HPLC 
analyses, that Kineret is stable for at least 4 hours at ambient temperature and in light in 
0.9%NaCl and in a plastic culture vial.38 
 
• Group 1 will receive intra-articular injection of Anakinra (Kineret®,  IL-1ra; 150mg) 1-
28 days after ACL injury.

STUDY PROCEDURES AND SCHEDULE 
 
7.1 
STUDY PROCEDURES/EVALUATIONS 
 
7.1.1 STUDY RELATED   
 
Demographic information:  Demographic data to be collected at Visit 1 will include height, 
weight, date of birth, age, gender and race. 
 
Medical and Medication History A detailed past medical history and a list of current 
medication, to include prescription and over-the-counter medications, will be collected at Visit 1.  
Assessment of eligibility should include a review of permitted and prohibited medications. Both 
the medical and medication history will be reviewed with the subject throughout the study for 
any changes in baseline history. 
 
Physical examination including vital signs, height, weight, BMI. All subjects must have a 
clinical exam that is consistent with an ACL tear at Visit 1. All subjects will have range of 
motion (ROM) collected at all visits. 
 
Knee Aspiration:  All subjects undergo knee aspiration to dryness at initial encounter Visit 1 (1-
28 days after ACL injury), Visit 2 (the time of surgery) and again at Visit  3 (4-14 days post-op).   
Should a subject be enrolled into the study and choose not to undergo ACL reconstruction, 
subject will receive treatment according to this protocol but, aspiration at time of surgery will be 
omitted. 
 
Assessment of Pain and Function –Subject Reported Outcomes – The study will use the 
standardized subject self-report Knee Injury and Osteoarthritis Outcome Score (KOOS) 
instrument to assess pain and function in response to the intervention for acute ACL injury. The 
KOOS is a 100 item instrument that consists of 5 subscales (pain, other symptoms, function in 
daily living, function in sport and recreation, and knee-related quality of life). The 5 separate 
subscales provide a complete picture of patients' perceptions of their knee injury and 
consequences to their daily activities, etc.. KOOS includes the WOMAC osteoarthritis index, 
which allows for potential comparison with other earlier studies. The KOOS has high test-retest 
reproducibility (ICC > 0.75). The KOOS subscales for function in sport and recreation and knee-
related quality of life have been shown to be the most sensitive subscales pre-operatively and 
change the most post-operatively (27).  The study will supplement the KOOS with self-reported 
function score assessments from the International Knee Documentation Committee (IKDC) form 
for evaluation of knee ligament injuries (28) as well as the. Veterans Rand 12-Item (VR-12) 
health survey and the Patient Acceptable Symptoms State (PASS) question. The questionnaires 
will be assessed either via an internet based collection software that allows secure data collection

through a password coded entry portal or during routine clinical visits using an IPad or paper 
forms. Paper forms may be used during routine clinical visits or directly mailed to patients. 
  
Specific Pain assessments - Pain coping strategies are important in understanding improvements 
in pain and psychological disability [46-48].  This study will use a simple Likert pain scale as a 
pain assessment tools (Figure 3). Pain catastrophizing has been identified as one of the strongest 
predictors of pain and has been defined as “an individual’s tendency to focus on and exaggerate 
the threat value of painful stimuli and negatively evaluate one’s own ability to deal with pain.” 
[49] Not only do individuals who catastrophize, experience more experimental pain (29-31) but 
also, catastrophizing has been shown to account for 7% to 31% of the variance in pain ratings in 
varied populations of patients having persistent pain.  
 
MRI analysis: All subjects will undergo MRI examination following Visit 1 and subsequent 
MRIs will be performed at Visits 5 and 6. Sagittal and axial MRI images will be acquired using a 
3.0-T MRI scanner and an 1Tx/15Rx phased array knee coil. Sagittal and axial T1-weighted spin 
echo images (FSE) will be acquired to allow semi-quantitative analysis at the conclusion of the 
study. These sequences will be followed by a sagittal high-resolution 3D dual echo steady state 
(DESS) sequence for cartilage segmentation and a sagittal combined T1ρ/T2 mapping for the 
quantification of cartilage composition. The major parameters for the DESS sequences are: FOV 
= 140 mm, matrix = 384×307×176, resolution = 0.36×0.45×0.7 mm3, time of repetition 
(TR)/time of echo (TE) = 17.6ms/6.0ms. The T1ρ/T2 mapping will be acquired using a 3D 
MAPSS sequence with major parameters: FOV = 140 mm, image matrix = 320×160×24, 
resolution = 0.44×0.44×4 mm3, time of recovery = 1.5 seconds, bandwidth = 400 Hz/Pixel, 
TR/TE = 7ms/3ms, time of spin lock (TSLs) = 0, 10, 40, 80 ms for T1ρ mapping and preparation 
TEs = 0, 20, 40, 60 ms for T2 mapping. The scan time will be approximately 12 minutes for the 
combined T1ρ/T2 mapping. Images will obtained with the knee in full extension.  
 
Images collected at the University of Kentucky will then be transferred digitally to the University 
of California, San Francisco to be analyzed by Dr. Majumdar and her laboratory. Based on the 
high resolution DESS images, articular cartilage will be segmented using a spline-based, 
semiautomatic technique. The T1ρ map will be created on a voxel-by-voxel basis using 
established fitting routines. The segmented masks will then be overlaid on the T1ρ maps after 
registration between DESS and T1ρ images, and mean T1ρ  values will be calculated for the 
entire tibiofemoral cartilage, medial and lateral tibial plateau, medial and lateral femoral 
condyles, and the patellofemoral compartment  will be calculated.

7.1.2 STANDARD OF CARE STUDY PROCEDURES  
 
Radiographic Analysis: 
Plain x-ray analysis: All subjects would have undergone a routine clinical x-ray analysis prior to 
Visit 1.   This includes bilateral x-ray views of the knee joint using a standing a/p, synaflexer 
standardized flexion weight bearing p/a (Synarc®), Merchant views and weight bearing lateral 
views. Radiographs will be assessed to determine study eligibility as open growth plates are an 
exclusion criteria. Plain radiographs will be reviewed for radiographic progression of joint space 
narrowing or osteophyte formation using the Kellgren-Lawrence classification system as well as 
the Iwano classification for the patello-femoral joint.  
 
Previous studies have shown that that joint space narrowing measured on a standardized 
synaflexor platform has a high reproducibility and accuracy. At 2 years koint space narrowing 
has been identified in an ACL injured cohort using this system (32).  
 
7.2 
LABORATORY PROCEDURES/EVALUATIONS 
 
7.2.1 CLINICAL LABORATORY EVALUATIONS  
 
Clinical Laboratory Evaluations: none 
 
Pregnancy test: Female participants of child bearing potential will have a urine pregnancy test at 
Visit 1.  Pregnancy testing results must be negative in order for enrollment into the study.  
 
Procedure for minors: A female minor is identified as a potential candidate for the study. The 
investigator or approved study staff approach the patient and accompanying parent/guardian to 
inform them that the patient may qualify for a study.  Both parties are informed of the study.  If 
interested in participating in the study, each research team will perform a pregnancy test for 
inclusion/exclusion in correspondence with their locally approved minor pregnancy testing 
protocol.

Sample collection including joint arthrocentesis. Synovial fluid will be aspirated and spun at 
3500 RPM for 10 minutes and the supernatant will be frozen at -70°C. Joint aspiration will be 
performed aseptically with local anesthesia through a superolateral suprapatellar approach.  The 
aspiration syringe will be gently removed and the study drug/placebo-containing syringe will be 
attached, followed by injection. The supernatants will be stored, pending analysis, in the UK 
Center for Clinical and Translational Science Bioanalysis Lab.  All biomarker analyses in 
synovial fluid, serum, and urine will be performed by co-Investigator Dr. Virginia Kraus at Duke 
University.  
 
IL-1ß, IL-1α, IL-6 and IL-1Ra analyses - These cytokines will be measured in the 
synovial fluid using the high-sensitivity Quantikine (sandwich) Immunoassays (R&D).  As 
described previously (39), the standard curve will be extended in the low range for the IL-1α 
assay to further improve the specificity as we have found the standard curve of the assay to be 
reproducible and linear below the lower standard described in the procedural literature 
accompanying the reagents.    
 
 
Glycosaminoglycan (GAG) - The S-GAG content, a marker of proteoglycan degradation, 
will be measured in synovial fluid with the dimethyl methylene blue dye (DMMB) assay as 
noted previously (40). Chondroitin sulfate from shark cartilage will be used as a standard 
between 5 and 50 mg/ml.   
 
Type II collagen (cartilage) degradation assay - CTX-II is derived from the C-terminal 
crosslinked telopeptide of type II collagen. Following degradation of cartilage it is released into 
the synovial fluid, the circulation, and subsequently secreted into urine. CTX-II correlates with 
the degree of joint destruction and increases significantly within one month after ACL tear 
(P=0.012)(41).  CTX-II will be measured in synovial fluid by ELISA (IDS, Herlev, Denmark 
(42).  
 
 
Type I collagen (meniscus) degradation assay – NTX-I is derived from the N-
telopeptide of type I collagen and was significantly elevated in synovial fluid after acute ACL 
tear (P=0.008) in our pilot study (42)  We will measure NTX-I in synovial fluid by ELISA(42) In 
serum it is considered to be indicative of bone resorption. In synovial fluid in the setting of acute 
joint injury we believe it to be indicative of meniscal injury and metabolism due to the fact that 
meniscus is primarily a type I collagen containing tissue.  
 
 
Cartilage Oligomeric Matrix Protein (COMP) - COMP is a pentameric, anionic, 
noncollagenous glycoprotein and member of a thrombospondin family of extracellular proteins 
that was initially isolated from cartilage (43) Although other joint tissues express COMP (44), it 
is most abundant in articular cartilage. Serum COMP levels are representative of cartilage 
catabolism (45,46) and we have demonstrated that serum COMP is associated with the presence 
and severity of radiographic OA and progression of OA [60]. COMP will be measured by 
sandwich ELISA (Biovendor) with mAbs 17C10 and 16F12 a recombinant COMP standard with 
an assay range of 0.1-32 U/L and the CV is <5%. 
 
 
Xanthine Oxidase (XO) - generates superoxide, a powerful reactive oxygen species. 
Synovial fluid XO is indicative of oxidative stress and increases in the first month after joint 
injury (Kraus unpublished data). It is measured by a multistep enzymatic reaction available from 
Cayman Chemical (Ann Arbor, Michigan) whose end product resorufin, is a highly fluorescent 
compound that can be easily analyzed using an excitation wavelength of 520-550 nm and an 
emission wavelength of 585-595 nm.

ASSESSMENT OF SAFETY 
 
8.1 
SPECIFICATION OF SAFETY PARAMETERS 
 
8.1.1 DEFINITION OF ADVERSE EVENTS (AE) 
 
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)). 
 
 
 
 


EASI ACL 
Version 7.0 
 
3 March 2020 
30 
 
8.1.2 DEFINITION OF SERIOUS ADVERSE EVENTS (SAE) 
 
Serious adverse event or serious suspected adverse reaction. An AE or suspected adverse 
reaction 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, 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 patient or 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. 
 
8.1.3 DEFINITION OF UNANTICIPATED PROBLEMS (UP) 
 
OHRP considers unanticipated problems involving risks to participants 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 IRB-approved research  
   protocol and informed consent document; and (b) the characteristics of the participant  
   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 participants or others at a greater risk of harm (including 
   physical, psychological, economic, or social harm) than was previously known or 
   recognized.  
 
This study will use the OHRP definition of UP. 
 
8.2 
CLASSIFICATION OF AN ADVERSE EVENT 
 
8.2.1 SEVERITY OF EVENT 
 
All AEs will be assessed by the clinician using a protocol defined grading system.  The protocol 
defined grading system to be used is:  
 
• Mild – Events require minimal or no treatment and do not interfere with the participant’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 participant’s usual daily activity and may require systemic drug  
  therapy or other treatment. Severe events are usually potentially life-threatening or  
  incapacitating. 
 
 
 


EASI ACL 
Version 7.0 
 
3 March 2020 
31 
 
8.2.2 RELATIONSHIP TO STUDY AGENT 
 
All AEs will have their relationship to study agent or study participation assessed with a level of 
specificity appropriate to the study design. The clinician’s assessment of an AE's relationship to 
study agent (drug) is part of the documentation process, but it is not a factor in determining what 
is or is not reported in the study. If there is any doubt as to whether a clinical observation is an 
AE, the event should be reported. All AEs must have their relationship to study agent assessed. 
In a clinical trial, the study product must always be suspect. To help assess, the following 
guidelines are used.  
 
• Related – The AE is known to occur with the study agent, there is a reasonable possibility 
   that the study agent caused the AE, or there is a temporal relationship between the study  
   agent and event. Reasonable possibility means that there is evidence to suggest a causal  
   relationship between the study agent and the AE.  
• Not Related – There is not a reasonable possibility that the administration of the study  
  agent caused the event, there is no temporal relationship between the study agent and event  
  onset, or an alternate etiology has been established. OR For all collected AEs, the clinician 
  who examines and evaluates the participant will determine the AE’s causality based on  
  temporal relationship and his/her clinical judgment. The degree of certainty about causality  
  will be graded using the categories below.  
 
1. Definitely Related – There is clear evidence to suggest a causal relationship, and 
other possible contributing factors can be ruled out. The clinical event, including an 
abnormal laboratory test result, occurs in a plausible time relationship to drug 
administration and cannot be explained by concurrent disease or other drugs or 
chemicals. The response to withdrawal of the drug (dechallenge) should be clinically 
plausible. The event must be pharmacologically or phenomenologically definitive, 
with use of a satisfactory rechallenge procedure if necessary.  
 
2. Probably Related – There is evidence to suggest a causal relationship, and the 
influence of other factors is unlikely. The clinical event, including an abnormal 
laboratory test result,    occurs within a reasonable time after administration of the 
drug, is unlikely to be attributed to concurrent,  disease or other drugs or chemicals, 
and follows a clinically reasonable response on withdrawal (dechallenge). Rechallenge 
information is not required to fulfill    this definition.  
 
3.  Possibly Related – There is some evidence to suggest a causal relationship (e.g., the 
event occurred within a reasonable time after administration of the trial medication). 
However, other factors may have contributed to the event (e.g., the participant’s 
clinical condition, other concomitant events). Although an AE may rate only as 
“possibly related” soon after discovery, it can be flagged as requiring more 
information and later be upgraded to “probably related” or “definitely related,” as 
appropriate.  
 
4.  Unlikely to be related – A clinical event, including an abnormal laboratory test 
result, whose temporal relationship to drug administration makes a causal relationship 
improbable (e.g., the event did not occur within a reasonable time after administration 
of the trial medication) and in which other drugs or chemicals or underlying disease 
provides plausible explanations (e.g., the participant’s clinical condition, other 
concomitant treatments).  
 


EASI ACL 
Version 7.0 
 
3 March 2020 
32 
 
5. 
Not Related – The AE is completely independent of study drug administration, 
and/or evidence exists that the event is definitely related to another etiology. There 
must be an alternative, definitive etiology documented by the clinician 
 
8.2.3 EXPECTEDNESS  
 
Expected adverse reactions are AEs that are common and known to occur for the study agent 
being studied and should be collected in a standard, systematic format using a grading scale 
based on functional assessment or magnitude of reaction.  
 
An AE or suspected adverse reaction is considered "unexpected" if it is not listed in the IB or is 
not listed at the specificity or severity that has been observed; or, if an IB is not required or 
available, is not consistent with the risk information described in the general investigational plan 
or elsewhere in the protocol or the USPI, as amended. For example, under this definition, hepatic 
necrosis would be unexpected (by virtue of greater severity) if the IB referred only to elevated 
hepatic enzymes or hepatitis. Similarly, cerebral thromboembolism and cerebral vasculitis would 
be unexpected (by virtue of greater specificity) if the IB listed only cerebral vascular accidents. 
"Unexpected," as used in this definition, also refers to AEs or suspected adverse reactions that 
are mentioned in the IB as occurring with a class of drugs or as anticipated from the 
pharmacological properties of the drug, but are not specifically mentioned as occurring with the 
particular drug under investigation.  
 
The Principal Investigator will be responsible for determining whether an 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 agent. 
 
8.3 
TIME PERIOD AND FREQUENCY FOR EVENT ASSESSMENT AND 
FOLLOW-UP 
 
The occurrence of an AE or SAE may come to the attention of study personnel during study 
visits and interviews of a study participant 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 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  as 
well as seriousness 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 participant is screened will be 
considered as baseline and not reported as an AE. However, if the study participant’s condition 
deteriorates at any time during the study, it will be recorded as an AE. UPs will be recorded in 
the data collection system throughout the study.  
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 PI 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 investigator will inquire about the occurrence of AE/SAEs 
since the last visit. Events will be followed for outcome information until resolution or 
stabilization.

8.4 
REPORTING PROCEDURES 
 
8.4.1 ADVERSE EVENT REPORTING  
 
The Principal Investigator will assess the occurrence of AEs throughout the subjects’ 
participation in the study.  Subjects will be followed for toxicity for 30 days after treatment has 
been discontinued or until death, whichever occurs first.  The clinical course of each event will 
be followed until resolution, stabilization, or until it has been determined that the study treatment 
or participation is not the cause.   
 
The investigator is responsible for ensuring that all adverse events observed by the investigator 
or reported by the subject, which occur after the subject has signed the informed consent, are 
fully recorded in the subject’s case report form, subject’s medical records, and/or any other 
institutional requirement.  Source documentation must be available to support all adverse events.  
 
A laboratory test abnormality considered clinically relevant (e.g., causing the subject to 
withdraw from the study), requiring treatment or causing apparent clinical manifestations, or 
judged relevant by the investigator, should be reported as an adverse event.   
 
The investigator will provide the following for all adverse events: 
• Description of the event 
• Date of onset and resolution 
• seriousness of the event  
• Attribution of relatedness to the investigational agent 
• Action taken as a result of the event 
• Outcome of event 
 
The Principal Investigator will report adverse events to the IRB according to their policies and 
procedures in reporting adverse events.   
 
8.4.2 SERIOUS ADVERSE EVENT REPORTING  
 
Investigator Reporting to the FDA:   Adverse reactions will be reported promptly to the Food 
and Drug Administration (FDA) via Medwatch by the Sponsor if the type of event is serious, 
unlisted/unexpected and possibly related to the study drug.  A clear description of the suspected 
reaction will be provided along with an assessment as to whether the event is drug or disease 
related.  The Sponsor will call the FDA as soon as he/she is aware (within ten (10) working days) 
that an adverse reaction has occurred.  The phone number for the FDA is 301-594-5778.   
 
The study sponsor will be responsible for notifying FDA of any unexpected fatal or life-
threatening suspected adverse reaction as soon as possible but in no case later than 7 calendar 
days after the sponsor's initial receipt of the information.  
 
The Principal Investigator will complete an Internal Prompt Reporting Form within the following 
timelines:

The reporting of serious adverse events to the study sponsor does not relieve the investigator  
from other regulatory reporting responsibilities. 
 
Investigator reporting to SOBI:  The Sponsor must inform Swedish Orphan Biovitrum (SOBI) in 
writing using a SOBI SAE or a MEDWATCH 3500A form of any SAE, independent of 
causality. The written report must be completed and supplied to SOBI by e-mail or facsimile 
within 24 hours/1 business day of first awareness. The initial report must be as complete as 
possible, including an assessment of the causal relationship between the event and the 
investigational product(s), if available. Information not available at the time of the initial report 
(e.g., an end date for the adverse event or laboratory values received after the report) must be 
documented on a follow-up report.  
 
A final report to document resolution of the SAE is required. A copy of the email transmission of 
the SAE report to SOBI (drugsafety@sobi.com) should be attached to the SAE and retained with 
the patient records.

8.4.3 UNANTICIPATED PROBLEM REPORTING  
 
Incidents or events that meet the OHRP criteria for UPs require the creation and completion of 
an UP report form. It is the site investigator’s responsibility to report UPs to their IRB and to the 
DCC/study sponsor. 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 SAEs will be reported to the IRB and to the DCC/study sponsor within of the  
  investigator becoming aware of the event.  
• Any other UP will be reported to the IRB and to the DCC/study sponsor within of the  
  investigator becoming aware of the problem.  


EASI ACL 
Version 7.0 
 
3 March 2020 
36 
 
• All UPs should be reported to appropriate institutional officials (as required by an  
  institution’s written reporting procedures), the supporting agency head (or designee), and 
  OHRP within (insert timeline in accordancy with policy) of the IRB’s receipt of the report  
  of the problem from the investigator.  
 
8.4.4 EVENTS OF SPECIAL INTEREST  
 
Not applicable. 
 
8.4.5 REPORTING OF PREGNANCY  
 
Pregnancy is neither an AE nor SAE.  All subject pregnancy must be reported to their study 
doctor or study staff immediately.  Once confirmed, study medication will be stopped and the 
study site will request permission from the woman to follow her for pregnancy outcomes.  All 
confirmed pregnancies will be reported to the study sponsor, FDA, SOBI  and IRB and followed 
until resolution (i.e., termination [voluntary or spontaneous] or birth) to assess for pregnancy-
associated AEs or SAEs such as congential anomaly.   
 
8.5 
STUDY HALTING RULES  
 
Administration of study agent will be halted when three grade 3 AEs determined to be “probably 
related” are reported to the FDA/IRB and enrollment screens will stop accepting new study 
participants. The study sponsor will inform the DSMB members within 24 hours of this 
occurrence and will provide the DSMB with AE listing reports. The DSMB will convene an ad 
hoc meeting by teleconference or in writing as soon as possible. The DSMB will provide 
recommendations for proceeding with the study to the study sponsor.  The study sponsor will 
inform the FDA of the temporary halt and the disposition of the study. 
 
Study Stopping Criteria 
 
• Local intolerance of the administered Kineret or any sign of allergic response. 
• Development of signs and symptoms before the second time point preventing the second 
administration of the study drug. 
• Any patient reported drug related SAE after the first or second administration of the study 
drug. 
• Diagnosis with any condition as outlined in the exclusion criteria during the course of the 
initial 2 weeks of study enrollment. 
 
 
8.6 
SAFETY OVERSIGHT 
 
Monitoring for adverse events will be conducted in real-time by the study investigators and study 
coordinators.  Risks involved with this study are considered greater than minimal risk.  For this 
reason, we will utilize the standing independent Data Safety Monitoring Board (DSMB) as 
chartered by the Center for Clinical and Translational Science (CCTS).  The DSMB will meet 
semiannually or as needed, and will review subject recruitment, AE’s, side effects, laboratory 
results, dropouts, protocol violations, and inclusion/exclusion criteria.  More frequent meetings 
will take place if side effects or other problems are prevalent.

CLINICAL MONITORING 
 
Clinical site monitoring will be performed by Bluegrass Research Consultants Inc. The monitor 
will conduct monitoring to verify that a) the rights and well-being of human subjects are 
protected; b) the reported trial data are accurate, complete and verifiable from source documents; 
c) the conduct of the trial is in compliance with the currently approved protocol/amendment(s), 
Food and Drug Administration (FDA) regulations and ICH guidelines d) Provide practical 
guidelines for Site Monitors, Study Monitors and Medical Monitors; e) Provide consistent 
monitoring procedures across all clinical sites; f) Ensure the quality and integrity of clinical 
study data; g) Evaluate the progress of the study and ensure completion of the clinical study in a 
timely manner.  A monitoring visit report will be provided to the Sponsor within 21 business 
days following the completion of a visit. 
 
The first monitoring visit will be conducted within two weeks following enrollment of the first 
subjects.  Subsequent monitoring visits will be completed based on enrollment and are expected 
to occur every four to six weeks.

STATISTICAL CONSIDERATIONS  
10.1 STATISTICAL AND ANALYTICAL PLANS 
 
10.1.1 GENERAL APPROACH 
 
Sample Size and Power Analysis - The primary outcome aim of the study is to determine if 
treatment with the study medication results in greater improvements in patient-reported 
outcomes one year following surgery.  We will use the validated Knee Osteoarthritis and injury 
Outcome Score (KOOS),[27] which is a self-administered, knee-specific instrument that 
evaluates the course of knee injury and treatment outcomes. To reduce the risk of an 
underpowered RCT, an a priori sample size estimation was calculated from data collected from 
recent studies of ACL-injured and –reconstructed patients.[28-32] The previously published one-
year KOOS Quality of Life Scores are 60.2 ± 24.2 [31] and the minimal detectable change of this 
instrument is 7.2 [32]. Assuming that the standard deviation of the change scores between the 
day of surgery and one year postoperative visits will be 20% of the standard deviation of the 
standard deviation of the one-year KOOS Quality of Life Scores (.2 x 24.2 = 4.8), a sample size 
of 16 patients per group (32total) would be at least 80% powered to detect a difference of 7.2 
points between the treatment group and the control group (One-way ANOVA model with alpha 
= 0.05, Effect size = 7.2/4.8 = 1.5, G*Power 3.0.10).  This sample size would adequately power 
the study for the primary outcome variable, but would also adequately power the study for the 
second aim of the study. The second aim of the study is to compare chondrodegenerative 
biomarkers between groups at the 1 year follow up. We have previously observed large effect 
sizes between groups in preliminary studies (ES = 1.34), and a sample size of 32 patients (16 per 
group) would be at least 80% powered to detect effect sizes of this magnitude.  However, to 
protect against an underpowered study due to patient attrition, we will monitor compliance and 
potentially enroll up to 20 patients per group in order to adjust for attrition. Patient costs will not 
occur until sample or MRI analysis.  
 
The power calculations include several caveats. First, for purposes of power calculation, we did 
not assume a full repeated measures analysis, but instead analyzed at a single time point (one-
year follow-up). Second, we note that in trials such as this, the power of a non-parametric 
analysis is never much lower than its parametric analog (the “asymptotic relative efficiency” of 


EASI ACL 
Version 7.0 
 
3 March 2020 
38 
 
the Wilcoxon test is at least 0.95), leading us to conclude that our parametrically based power 
calculations should apply with equal force to a non-parametric analysis.   
 
Statistical analyses - Results from a sample of this size may not be normally distributed. 
Therefore, non-parametric statistical measures may be used.  Primary outcome measures 
evaluating for change in KOOS will be assessed at multiple points and will be analyzed for 
change between groups using Friedman two-way ANOVA for repeated measures. Synovial fluid 
analyses comparing the three groups at five time points will be analyzed using the Wilcoxon 
Signed Rank Sum Test with Hochberg corrections for multiple time points.  Alternatively, if 
results are normally distributed or can be transformed (e.g., by log transformation) to meet the 
criteria for normality for parametric analysis, then repeated measures ANOVA will be utilized 
comparing treatment groups.  P-values of less than or equal to 0.05 will be considered 
statistically significant. 
  
Predicted Results:  IL-1ra, while potent, has had mixed results in the treatment of established 
OA, possibly due to it’s short half-life in vivo. In this trial, we expect that an early intervention 
with IL-1ra will effectively block the deleterious cascade of joint degradation events after joint 
injury.  We expect a significant effect of IL-1ra on post-injury pain and concomitantly an 
increase in patient-reported outcomes due to the improved early function 
 
Minimization of bias: Due to the randomized study design and the blinding of the investigator 
and patient to the drug used, we hope to eliminate any investigator or subject bias. Using broad 
and previously established enrollment criteria we hope to reduce selection bias to a minimum 
while protecting potentially vulnerable individuals through the exclusion criteria. Procedural bias 
and measurement bias will be reduced by the multicenter design and the blinded data analysis. 
  
10.1.2 ANALYSIS OF THE PRIMARY EFFICACY ENDPOINT(S) 
 
A safety review of treatment Groups 1 and 2will be performed.  Safety endpoints will be 
monitored at each study visit and at each monitoring visit.  
 
Study Stopping Criteria 
 
• local intolerance of the administered Kineret or any sign of allergic response. 
• development of signs and symptoms before the second time point preventing the second 
administration of the study drug. 
• Any patient reported SAE after the first or second administration of the study drug. 
• Diagnosis with any condition as outlined in the exclusion criteria during the course of the 
initial 2 weeks of study enrollment. 
 
10.1.3 ANALYSIS OF THE SECONDARY ENDPOINT(S) 
 
Not applicable 
 
10.2 MEASURES TO MINIMIZE BIAS 
 
10.2.1 ENROLLMENT/ RANDOMIZATION/ MASKING PROCEDURES 
 
Randomization:  Following informed consent and after successfully being screened into the 
study, subjects will be randomized to one of three treatment groups.   
 


EASI ACL 
Version 7.0 
 
3 March 2020 
39 
 
• Group 1 will receive intra-articular injection of Anakinra (Kineret®,  IL-1ra; 150mg) 1-
28 days after ACL injury.  
• Group 2 will receive intra-articular injection of saline placebo 1-28 days after ACL 
injury.  
 
Blinding: To ensure triple-blindness, an uninvolved third party will generate the allocation 
sequence of the intervention and provide this to the principal investigator.  Allocation of drug or 
placebo will be by permutated random block size, ensuring that approximately equal numbers of 
subjects will be treated with drug or placebo in the unlikely event that the study will need to be 
terminated prematurely. 
 
If subject discontinues the study for any reason prior to 3-month visit, then the collected data will 
be evaluated but not included in the analysis and a replacement subject will be enrolled in the 
study. 
 
10.2.2 EVALUATION OF SUCCESS OF BLINDING  
 
Not applicable. 
 
10.2.3 BREAKING THE STUDY BLIND/PARTICIPANT CODE 
 
Breaking the randomization code will be performed by the Principal Investigator and will occur 
if  it is necessary for the care of the subjects.  For example, if an AE or SAE occurs with the a 
subject and knowledge of the drug randomization would be important for clinical care or to 
determine appropriate treatment, then the principal investigator will break the code and the 
subject will be withdrawn from the study. 
 
Unblinding of a subject(s) dosing will be documented and will include an explanation of why the 
study medication was unblinded. 
 
Following data lock, subject dosing information can be unblinded and the unblinded information 
can be sent to the study participants at the discretion of the principal investigator. 
 
11 
SOURCE DOCUMENTS AND ACCESS TO SOURCE 
DATA/DOCUMENTS 
 
The principal investigator will maintain appropriate medical and research records for this trial, in 
compliance with ICH E6 and regulatory and institutional requirements for the protection of 
confidentiality of participants.  The principal investigator will permit authorized representatives 
of the FDA, Institutional Review Board, Center for Clinical and Translational Science, Bluegrass 
Research Consultants, Inc. and regulatory agencies to examine (and when permitted by 
applicable law, to copy) clinical records for the purposes of quality assurance reviews, audits, 
and evaluation of the study safety, progress, and data validity.  
 
Source data are all information, original records of clinical findings, observations, or other 
activities in a clinical trial necessary for the reconstruction and evaluation of the trial. Examples 
of these original documents and data records include, but are not limited to, hospital records, 
clinical and office charts, laboratory notes, memoranda, participant’s memory aids or evalulation 
checklists, pharmacy dispensing records, recorded audio tapes of counseling sessions, recorded 
data from automated instruments, copies or transcriptions certified after verification as being 
accurate and complete, microfiches, photographic negatives, microfilm or magnetic media, x-

rays, and participant files and records kept at the pharmacy, at the laboratories, and medico-
technical departments involved in the clinical trial.  
 
It is not acceptable for the CRF to be the only record of a patient’s participation in the study.  
This is to ensure that anyone who would access the patient medical record has adequate 
knowledge that the patient is participating in a clinical trial. 
 
12 
QUALITY ASSURANCE AND QUALITY CONTROL 
 
Quality Control rocedures will be implemented beginning with the data entry system and data 
QC checks that will be run on the database will be generated. Any missing data or data 
anomalies will be communicated to the site(s) for clarification/resolution.  
 
Following written SOPs, the monitors will verify that the clinical trial is conducted and data are 
generated, documented (recorded), and reported in compliance with the protocol, GCP, and the 
applicable regulatory requirements (e.g., Good Laboratory Practices (GLP), Good Manufacturing 
Practices (GMP)).  
 
The investigational site will provide direct access to all trial related sites, source data/documents, 
and reports for the purpose of monitoring and auditing by the sponsor, and inspection by local 
and regulatory authorities.

13.3.1 CONSENT/ASSENT AND OTHER INFORMATIONAL DOCUMENTS 
PROVIDED TO PARTICIPANTS 
 
Consent forms describing in detail the study agent, study procedures, and risks are given to the 
participant and written documentation of informed consent is required prior to starting 
intervention/administering study product. The following consent materials are submitted with 
this protocol. 
 
13.3.2 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. Extensive discussion of 
risks and possible benefits of participation will be provided to the participants and their families. 
Consent forms will be IRB-approved and the participant will be asked to read and review the 
document. The investigator will explain the research study to the participant and answer any 
questions that may arise. All participants will receive a verbal explanation in terms suited to their 
comprehension of the purposes, procedures, and potential risks of the study and of their rights as 
research participants. Participants will have the opportunity to carefully review the written 
consent form and ask questions prior to signing. The participants should have the opportunity to 
discuss the study with their surrogates or think about it prior to agreeing to participate. The 
participant will sign the informed consent document prior to any procedures being done 
specifically for the study. The participants may withdraw consent at any time throughout the 
course of the trial. A copy of the informed consent document will be given to the participants for 
their records. The rights and welfare of the participants 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. 
 
13.4 PARTICIPANT AND DATA CONFIDENTIALITY  
 
Participant confidentiality is strictly held in trust by the participating investigators, their staff, 
and the sponsor(s) and their agents. This confidentiality is extended to cover testing of biological 
samples and genetic tests in addition to the clinical information relating to participants. 
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 sponsor. 
 
The study monitor, other authorized representatives of the sponsor, representatives of the IRB or 
pharmaceutical company supplying study product 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 participants in this study. The clinical 
study site will permit access to such records.  
 
The study participant’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 local IRB and Institutional regulations.  
 
Study participant research data, which is for purposes of statistical analysis and scientific 
reporting will not include the participant’s contact or identifying information. Rather, individual 
participants and their research data will be identified by a unique study identification number. 
The study data entry and study management systems used by clinical sites and by research staff

DATA HANDLING AND RECORD KEEPING  
 
14.1 DATA COLLECTION AND MANAGEMENT RESPONSIBILITIES  
 
Data collection is the responsibility of the clinical trial staff at the site under the supervision of 
the site PI. The 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. Black ink is required to ensure clarity of reproduced copies. When making 
changes or corrections, cross out the original entry with a single line, and initial and date the 
change. DO NOT ERASE, OVERWRITE, OR USE CORRECTION FLUID OR TAPE ON 
THE ORIGINAL. 
 
Copies of the CRF (CRF) will be provided for use as source documents and maintained for 
recording data for each participant enrolled in the study. Data reported in the CRF derived from 
source documents should be consistent with the source documents or the discrepancies should be 
explained and captured in a progress note and maintained in the participant’s official electronic 
study record.  
 
Clinical data (including AEs, concomitant medications, and expected adverse reactions data) and 
clinical laboratory data will be entered onto paper CRFs or a eCRF 21 CFR Part 11-compliant 
data capture system provided by the Sponsor. The data system includes password protection and 
internal quality checks, such as automatic range checks, to identify data that appear inconsistent, 
incomplete, or inaccurate. Clinical data will be entered directly from the source documents. 
 
14.2 STUDY RECORDS RETENTION  
 
Records should not be destroyed without the sponsor’s agreement.  Study documents should be 
retained for a minimum of 6 years in keeping with local IRB record retension policy.   
 
14.3 PROTOCOL DEVIATIONS  
 
A protocol deviation is any noncompliance with the clinical trial protocol, GCP, or MOP 
requirements. The noncompliance may be either on the part of the participant, 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 E6:  
 
 
• 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 site to use continuous vigilance to identify and report deviations 
within working days of identification of the protocol deviation, or within working days of the 
scheduled protocol-required activity. All deviations must be addressed in study source 
documents, reported to Program Official and protocol deviations must be sent to the local IRB 
per their guidelines. The site PI/study staff is responsible for knowing and adhering to their IRB 
requirements. Further details about the handling of protocol deviations will be included in the 
MOP. 
 
14.4 PUBLICATION AND DATA SHARING POLICY 
 
This study will comply with the NIH Public Access Policy, which ensures that the public has 
access to the published results of NIH funded research. It requires scientists to submit final peer-
reviewed journal manuscripts that arise from NIH funds to the digital archive PubMed Central 
upon acceptance for publication.  
 
The International Committee of Medical Journal Editors (ICMJE) member journals have adopted 
a clinical trials registration policy as a condition for publication. The ICMJE defines a clinical 
trial as any research project that prospectively assigns human subjects to intervention or 
concurrent comparison or control groups to study the cause-and-effect relationship between a 
medical intervention and a health outcome. Medical interventions include drugs, surgical 
procedures, devices, behavioral treatments, process-of-care changes, and the like. Health 
outcomes include any biomedical or health-related measures obtained in patients or participants, 
including pharmacokinetic measures and adverse events.  
 
The ICMJE policy, and the Section 801 of the Food and Drug Administration Amendments Act 
of 2007, requires that all clinical trials be registered in a public trials registry such as 
ClinicalTrials.gov, which is sponsored by the National Library of Medicine. Other biomedical 
journals are considering adopting similar policies. For interventional clinical trials performed 
under NIH IC grants and cooperative agreements, it is the grantee’s responsibility to register the 
trial in an acceptable registry, so the research results may be considered for publication in ICMJE 
member journals. The ICMJE does not review specific studies to determine whether registration 
is necessary; instead, the committee recommends that researchers who have questions about the 
need to register err on the side of registration or consult the editorial office of the journal in 
which they wish to publish. 
 
FDAAA mandates that a "responsible party" (i.e., the sponsor or designated principal 
investigator) register and report results of certain "applicable clinical trials":  
 • Trials of Drugs and Biologics: Controlled, clinical investigations, other than Phase I 
investigations, of a product subject to FDA regulation  
 • Trials of Devices: Controlled trials with health outcomes of a product subject to FDA 
regulation (other than small feasibility studies) and pediatric postmarket surveillance 
studies.  
 
NIH grantees must take specific steps to ensure compliance with NIH implementation of 
FDAAA.

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 trial. The 
study leadership in conjunction with the has established policies and procedures for all study 
group members to disclose all conflicts of interest and will establish a mechanism for the 
management of all reported dualities of interest.

Treatment in Patients with Acute ACL Tear and Painful Effusions

WHY ARE YOU BEING INVITED TO TAKE PART IN THIS RESEARCH? 
 
You are being invited to take part in a research study about Kineret®. You are being invited to take part 
in this research study because you are between the ages of 14-40, are active and have been diagnosed 
with an anterior cruciate ligament (ACL) tear.   
 
Kineret® was chosen because it is a well tolerated drug and has been used to treat Rheumatoid Arthritis 
(RA) and post-surgical persistent knee effusions (joint swelling) as well as knee stiffness. Although 
Kineret® is approved by the US Food and Drug Administration (FDA) for the treatment of RA and 
Neonatal-Onset Multisystem Inflammatory Disease, it is not currently approved by the FDA for use in 
treating ACL injury. Therefore, the use of Kineret® in this study is investigational.     
 
If you volunteer to take part in this study, you will be one of about 40 people to do so at the University 
of Kentucky. 
 
WHO IS DOING THE STUDY? 
 
The person in charge of this study is Cale Jacobs, PhD of University of Kentucky, Department of 
Orthopaedic Surgery and Sports Medicine. There may be other people on the research team assisting at 
different times during the study.  
 
WHAT IS THE PURPOSE OF THIS STUDY? 
 
Injury to the knee during sports participation often involves partial or full detachment of the anterior 
cruciate ligament (abbreviated as ACL).  ACL tears cause pain, swelling and inflammation.  While the 
swelling and inflammation usually goes away in time, individuals with ACL injuries may experience 
pain and notice knee instability (knee slipping, etc.).  Often surgery can repair or replace the ACL within 
the joint, allowing individuals the ability to walk or run again pain free or participate in sports.  
Unfortunately, osteoarthritis of the knee, which also causes pain and swelling, can occur in that same 
knee 10-20 years later for reasons which are not well understood. 
 
In this research study, we want to study how Kineret impacts initial pre-operative pain and to see if the 
use of Kineret does decrease the risk of developing arthritis in individuals with ACL injuries by treating 
them within 28 days after their injury.  
 
This research study is designed to allow health care professionals and researchers to answer many 
questions about the reasons why ACL injury leads to knee pain and disability and osteoarthritis.   
The purpose of this research is to gather information on how effective Kineret® is in alleviating knee 
pain following ACL rupture.   
 
The results of this study will be shared with Arthritis Foundation, the company providing Kineret®, 
Swedish Orphan Biovitrium (Sobi), the Food and Drug Administration and other federal agencies, if 
required, the University of Kentucky Center for Clinical and Translational Science, Duke University, the 
Cleveland Clinic Foundation, the University of California, San Francisco and Bluegrass Research 
Consultants.

You should not take part in this study if: 
• You are younger than 14 and older than 40 
• You are unable to provide informed consent 
• You have had prior surgery to your currently-injured knee 
• You have received corticosteroid injections into the injured knee within three months of 
enrollment into this study 
• You are allergic to Kineret® 
• 
You have received any live vaccines such as smallpox, MMR (measles, mumps and rubella), 
flu, polio, typhoid, chicken pox, yellow fever, herpes zoster 1 week prior to Visit 1, or are 
scheduled to receive a “live” vaccine within 1 week after study injection. 
• You have an infection (or signs/symptoms of an infection ie: fever), including infections of the 
skin, a history of infections that keep coming back or other problems that can increase your risk 
for infections 
• You are pregnant or planning to become pregnant 
• You are breastfeeding or plan to breastfeed 
• You have been diagnosed with hepatitis B or tuberculosis 
• You have a disease that weakens your immune system such as diabetes, cancer, HIV or AIDS 
• You have an underlying inflammatory disease (i.e. Rheumatoid Arthritis, Psoriatic Arthritis, etc.) 
• You are currently taking Kineret®, humira, enbrel or any other immune suppressive drugs for 
inflammatory disease 
• You have a history of bleeding disorders or are taking any blood thinning medications, aspirin or 
other medications affecting blood clotting 
• You are allergic to latex or tape 
• You have had a reaction to any local or general anesthesia  
• You have received any investigational drug within 4 weeks of study Visit 1 
 
WHERE IS THE STUDY GOING TO TAKE PLACE AND HOW LONG WILL IT LAST?  
 
The research procedures will be conducted at the UK Medical Center. You need to come to the UK 
Healthcare at Turfland located at 2195 Harrodsburg Road in Lexington, KY.  You will be asked to come 
to this location six times during the study.  Each of those visits will take about 30 minutes.   On the day 
of your surgery will need to come to the Center for Advanced Surgery at the University Of Kentucky 
Medical Center in Pavilion H. You will have three visits to campus to complete the research MRI scans, 
40 Whitney Hendrickson Bldg at 740 Rose St in Lexington, KY (Visit 1, 5 & 6).  All exams and 
questionnaires will be administered during the otherwise necessary routine visits for any participant who 
has suffered an ACL tear. No additional visit is necessary. The total amount of time you will be asked to 
volunteer for this study is about 3 1/2 hours, over the next 2 years. 
 
WHAT WILL YOU BE ASKED TO DO? 
 
A Summary of Study Procedures can be found as an attachment to this document.  More detailed 
information about some of the procedures is shown below.   
 
All participants with sports related ACL injuries enrolled in this study will be seen and may elect to 
undergo surgery, if necessary.  Note:  Surgery is not part of this protocol.  Should you be enrolled into 
the study and choose not to undergo ACL reconstruction (surgery), you will receive treatment according 
to this protocol.   
 
You will undergo knee aspirations (draining of fluid from the knee).  The first one is performed at Visit 
1 and is considered standard of care for your injury.  The next two (1 each at Visits 2 and 3) are required 
for the study.  Should a subject be enrolled into the study and choose not to undergo ACL reconstruction 
aspiration at time of surgery (Visit 2) will be omitted.

At Visit 1:  you may have a large effusion that requires aspiration.  This will be done as part of your 
normal routine care. 
 
At Visit 2:  you may have to undergo a study required aspiration depending on the amount of fluid in the 
knee. 
 
At Visit 3:  should you elect to undergo ACL reconstruction surgery, you will undergo a study required 
knee aspiration.  Should you elect not to undergo ACL reconstruction surgery, you will not undergo the 
knee aspiration. 
 
During a knee aspiration, the study doctor will remove fluid from the space around your knee using a 
needle and syringe. This is usually performed under a local anesthetic to either relieve swelling or to 
obtain fluid for analysis to diagnose a joint disorder and/or problem. Knee aspirations after ACL tear 
with a painful effusion are a common orthopaedic practice and standard of care in our institution. Thus 
they are not considered additional interventions with regard to this study unless you have no fluid in the 
knee. 
 
During each aspiration procedure:  Generally, a joint aspiration procedure follows this process: 
1. You will be positioned so that the study doctor can easily reach the joint that is to be aspirated. 
2. The skin over the joint aspiration site will be cleansed with an antiseptic solution. 
3. If a local anesthetic is used, you will feel a needle stick when the anesthetic is injected.  This 
may cause a brief stinging sensation. 
4. The study doctor will insert the needle through the skin into the joint.  You may feel some 
discomfort or pressure. 
5. The study doctor will remove the fluid by drawing it into a syringe that is attached to the needle. 
6. At Visit 1, the study medication (Kineret®/or saline) will be injected through the same needle. 
No medication will be injected in your knee at Visits 2 or 3. 
7. The needle will be removed and a sterile bandage or dressing will be applied.  
8. The fluid sample will be sent to a laboratory for examination.  
 
After the aspiration procedure:  Once you are home, it is important for you to keep the joint aspiration 
site clean and dry.  Leave the bandage in place for as long as instructed by your study doctor.  The 
aspiration site may be tender or sore for a few days after the joint aspiration procedure.  Take a pain 
reliever for soreness as recommended by your study doctor.  Be sure to take only recommended 
medications. 
 
Notify the study doctor to report any of the following: 
• Fever 
• Redness, swelling, bleeding, or other drainage from the aspiration site 
• Increased pain around the aspiration site 
 
Randomization:  Once it has been determined that you meet the entry requirements of the study you 
will be randomized, like drawing from a hat, into one of two groups. Both groups will receive knee 
injections with either Kineret® or a saline placebo.  The saline placebo will contain no active 
medication.   Neither you, or the study doctor, or the staff will know what treatment group you are 
assigned to.  However, if you have a medical emergency you study doctor will be able to find out what 
treatment group you have been assigned to.  If this is happens, you will removed from the study. 
 
• 
Group 1 will receive an injection of Anakinra (Kineret®, IL-1ra; 150mg) 1-28 days after ACL injury.  
• 
Group 2 will receive an injection of saline placebo 1-28 days after ACL injury.   
 
X-rays:  All subjects would have undergone a routine clinical x-ray analysis at prior to Visit 1.    
 
MRI:  All subjects will undergo initial MRI examination to confirm ACL injury at Visit 1 and 
subsequent MRIs will be performed at Visits 5 and 6.

Visit 1 Screening (1-28 days following injury)  
 
• Obtain informed consent and assent if necessary of potential subjects  
• Review medical history to determine eligibility based on inclusion/exclusion criteria.  
• MRI scheduled 
• Review medications history to determine eligibility based on inclusion/exclusion criteria.  
• Perform medical examinations and collect vital signs as needed to determine eligibility  
   based on inclusion/exclusion criteria. All subjects must have a clinical exam that is consistent with    
   an ACL tear. 
• Height and weight will be recorded 
• Collection of urine and blood for laboratory testing. Women of child bearing potential will be 
given a urine pregnancy test.  Test must be negative in order to enroll into the study.  Parents/Legal 
Guardians of minor females:  Your child will have a pregnancy test to see if they are eligible to be 
in the study.  The results will not be disclosed to anyone other than your child, except in the case 
of a risk to health or welfare.  
 
• Subjects will have the following assessments:  range of motion, knee instability (Lachman’s test) 
and standardized weight bearing x-rays.  At this time the subjects will also be asked to fill in a 
standard questionnaire covering the KOOS, IKDC, VR-12, and a Likert pain scale. 
   
Following the review of above assessment results and a review of inclusion/exclusion criteria, subjects 
will be randomized into 1 of 2 groups.  Following randomization, subjects will undergo a knee 
aspiration and will receive their first dose study medication.

The total amount of blood we will ask you to give is approximately 6 teaspoons. 
 
The blood and fluid samples we collect from you during the study will NOT UNDERGO GENETIC 
TESTING.  Your samples will be analyzed and stored at a University of Kentucky research laboratory.    
Your samples will be tested for special markers of cartilage breakdown and will remain property of the 
University of Kentucky indefinitely or until they are completely used. You may request that your 
samples be destroyed at any time.  Please inform your study doctor if you wish to have your study 
samples destroyed. 
 
Some of the fluid we collect will be sent to a research laboratory at Duke University where it will be 
tested for biomarkers.  A biomarker is a test that can be used to measure health, or the progress of 
disease or the effects of treatment. Your sample will be kept indefinitely or until they are completely 
used. 
 
The results we obtain from your analyzed samples are important only for research, not for helping to 
care for you.  For this reason, these results will not be released to you or your family. Should future 
discoveries with these samples identify a clinically important problem that requires treatment, you will 
be told of this. 
 
Your samples will be labeled with a barcode, but your name will not be provided. Your identity will 
remain confidential. All samples will be stored by barcode and no identifying information will be 
included with them. Your biomarker data will be stored in a locked file, and in a computer with 
restricted access. Any information that could be used to potentially identify you in the computer will be 
stored in a separate file and encrypted. Only the Principal Investigator and their research assistants will 
have access to the original research data. 
 
Data from your biomarker tests will not be revealed to family members, insurance companies, 
employers, or other individuals or organizations. Any information gained from this research will be 
reported in anonymous summary form. No information regarding the biomarker research will be entered 
into your regular medical record.  Although future research that uses your samples may lead to the 
development of new products, you will not receive any payments for these new products. 
All links with your identity will be removed from the sample.  You may request that your samples be 
destroyed at any time.  Please inform your study doctor if you wish to have your study samples 
destroyed. 
 
WHAT ARE THE POSSIBLE RISKS AND DISCOMFORTS? 
 
Kineret® may cause serious side effects, including: 
 
• Serious Infections. There is a very low risk that Kineret® may lower your ability to fight 
infections. During your treatment with Kineret, call your healthcare provider right away if you: 
 get an infection 
 have any sign of an infection including a fever or chills 
 have any open sores on your body

Do not receive "live" vaccines such as smallpox, MMR (measles, mumps and rubella), flu, polio, 
typhoid, chicken pox, yellow fever, herpes zoster, within 30 days of study entry without first talking to 
your study doctor. 
 
• Allergic reactions.  Get emergency help right away if you have any of these symptoms of a severe 
allergic reaction as an allergic reactions such as these may lead to death. 
 
swelling of your face, lips, mouth or tongue 
 
trouble breathing 
 
wheezing 
 
severe itching 
 
skin rash, redness, or swelling outside of the injection site area 
 
dizziness or fainting 
 fast heartbeat or pounding in your chest (tachycardia) 
 sweating 
 
The most common side effects of Kineret include injection site reaction.  Most injection site reactions 
are mild, happen early during treatment, and last about 14 to 28 days.  The symptoms of injection site 
skin reactions may include: 
 redness 
 swelling 
 bruising 
 itching 
 stinging 
 
Reproductive Risks:  It is not known whether receiving Kineret® is harmful to an unborn child.  
Pregnancy after administration of Kineret® may involve risks to the mother and her baby.  Therefore, 
female who are capable of having a child, must use effective contraceptive methods.  These methods 
must be used from the time of screening until Visit 2 during which any remaining medication will be 
washed out of the joint during the surgery.  If you do not elect to have surgery (Visit 2) contraception 
methods will be documented until the end of the study. Examples of effective birth control are:  
hormonal contraceptives (the pill, implant, transdermal patch, or injection), barrier methods (condom 
with spermicide, diaphragm with spermicide), IUD, or a male partner had a vasectomy. 
 
Lactating women:  It is not known whether Kineret® is excreted in human milk.  Because many drugs 
are excreted in human milk, you will not be allowed to participate in the study if you are breastfeeding.   
 
Local Anesthetic:  You may feel a brief stinging as the anesthetic is being injected.  Along with its 
needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may 
occur, if they do occur they may need medical attention. 
 
While you are in the hospital or your study medical doctor’s office, you will be carefully followed for 
any signs of allergic reaction.  However, some effects may not be noticed until later.  Check with your 
doctor immediately, or call 911 if any of the following side effects occur: 
 
• breathing problems 
• chest pain 
• convulsions (seizures) 
• dizziness 
• fever 
• headache 
• itching 
• nausea and/or vomiting 
• raised red swellings on the skin, lips, tongue, or in the throat 
• rapid heart rate 
• skin rash

Risks associated with knee joint aspirations:  As with any surgical procedure, complications can 
occur.  Some possible complications may include, but are not limited to, the following: 
 
• Fever 
• Pain or discomfort at the aspiration site 
• Bruising at the aspiration site 
• Redness, swelling, bleeding or other drainage from the aspiration site 
• Infection at the aspiration site 
 
Blood draws:   There is  a risk of local pain, soreness, bleeding, bruising and swelling, as well as 
lightheadedness, dizziness and rarely, fainting and/or a local infection.   
 
There is always a chance that any medical treatment can harm you, and the investigational treatment in 
this study is no different.  In addition to the risks listed above, you may experience a previously 
unknown risk or side effect. 
 
WILL YOU BENEFIT FROM TAKING PART IN THIS STUDY? 
 
We cannot and do not guarantee that you will receive any benefit from taking part in this study.   Your 
willingness to take part may, however, increase knowledge regarding the treatment of ACL injury and 
help future subjects. Previous studies using the study medication (Kineret®) in the knee joint after ACL 
injury or stiffness have resulted in  pain relief for the patient and you  may benefit from this effect. 
 
You will have physical examinations and laboratory tests provided to you at no cost.  Your study doctor 
will share with you any findings on these tests that indicate a potential problem. 
 
DO YOU HAVE TO TAKE PART IN THE STUDY? 
 
If you decide to take part in the study, it should be because you really want to volunteer.  You will not 
lose any benefits or rights you would normally have if you choose not to volunteer.  You can stop at any 
time during the study and still keep the benefits and rights you had before volunteering.  If you decide 
not to take part in this study, your decision will have no effect on the quality of medical care you 
receive. 
 
IF YOU DON’T WANT TO TAKE PART IN THE STUDY, ARE THERE OTHER CHOICES? 
 
If you do not want to take part in the study, you have the choice to undergo our standard treatment for 
ACL injuries. Standard of care treatment includes the aspiration of painful knee effusions (fluid in your 
knee), pre-surgical rehabilitation, reconstruction of the ACL ligament, and subsequent physical therapy. 
 
WHAT WILL IT COST YOU TO PARTICIPATE? 
 
You and/or your insurance company, Medicare or Medicaid will be responsible for the costs of all care 
and treatment you receive during this study that you would normally receive for your condition. These 
are costs that are considered medically reasonable and necessary and will be part of the care you receive 
if you do not take part in this study. These costs include the following: 
 
• Knee aspiration done at Visit 1 (if necessary) 
• Range of Motion at all study visits 
• X-Ray (if necessary) 
 
The University of Kentucky may not be allowed to bill your insurance company, Medicare or Medicaid 
for the medical procedures done strictly for research. The following will be provided at no cost to you:  
the injection of Kineret®, the second knee aspiration and potentially the third knee aspiration, 
questionnaires and three MRIs.

WHO WILL SEE THE INFORMATION THAT YOU GIVE? 
 
We will make every effort to keep private all research records that identify you to the extent allowed by 
law. 
 
Your information will be combined with information from other people taking part in the study. When 
we write about the study to share it with other researchers, we will write about the combined information 
we have gathered. You will not be personally identified in these written materials. We may publish the 
results of this study; however, we will keep your name and other identifying information private. 
 
In order to process your study payments, we will need to collect your social security number.  You do 
not have to give us this number however, refusing to provide us with your social security number may 
result in your not receiving study payment.  You can refuse to provide us your social security and still be 
enrolled into the study. 
 
We will make every effort to prevent anyone who is not on the research team from knowing that you 
gave us information, or what that information is.  
 
The study information collected from your participation in the study may be entered into a secure 
computer system.  The study doctor is committed to maintaining the privacy of every study subject and 
any personal information submitted and follows the principles of the Health Insurance Portability and 
Accountability Act (HIPAA) of 1996.  All data are stored at a secure site behind a firewall, which 
monitors and protects against unauthorized access. 
 
Your charts and any other items containing confidential items will be stored in a safe place overnight 
and not left on the desk.  Charts will not be left in an area where others might have access to them. 
 
You should know, however, that there are some circumstances in which we may have to show your 
information to other people.   For example, the law may require us to show your information to a court 
or to tell authorities if you report information about a child being abused or if you pose a danger to 
yourself or someone else. 
 
Officials of the University of Kentucky, the Arthritis Foundation, Sobi, members of an independent Data 
Safety Monitor Board, the Center for Clinical and Translational Science, Bluegrass Research 
Consultants and researchers at Duke University, the Cleveland Clinic Foundation, and University of 
California San Francisco (UCSF), may look at or copy pertinent portions of records that identify you. 
 
If you withdraw from the study or are withdrawn, data collected to that point will be kept. 
 
CAN YOUR TAKING PART IN THE STUDY END EARLY? 
 
If you decide to take part in the study you still have the right to decide at any time that you no longer 
want to continue. You will not be treated differently if you decide to stop taking part in the study. 
The individuals conducting the study may need to withdraw you from the study and the study 
medication will no longer be provided free of charge.  This may occur if you are not able to follow the 
directions they give you, if they find that your being in the study is more risk than benefit to you, or if 
the agency funding the study decides to stop the study early for a variety of scientific reasons.  
 
ARE YOU PARTICIPATING OR CAN YOU PARTICIPATE IN ANOTHER RESEARCH 
STUDY AT THE SAME TIME AS PARTICIPATING IN THIS ONE? 
 
You may not take part in this study if you are currently involved in another research study.  It is 
important to let the investigator/your doctor know if you are in another research study.  You should also 
discuss with the investigator before you agree to participate in another research study while you are 
enrolled in this study.

e.  Should a subject be enrolled into the study and choose not to undergo ACL reconstruction, subject will receive treatment according to this protocol.  
f.  All subjects must have standardized MTP-2 weight bearing x-ray.  Documentation of closed growth plates at screening will be noted in the routine SOC x-
ray 
g.  All subjects enrolled will have an MRI performed regardless if surgery is to be scheduled or not.  However, randomization can be performed prior to MRI 
as the MRI examination is not necessary or required to diagnose the ACL tear. 
h.  We will only perform the aspiration at Visit 3 if participants had elected to have surgery performed, and if they have fluid on their knee.
