SECTION V: RESEARCH PLAN
1. Statement of Purpose: State the scientific aim(s) of the study, or the hypotheses to be tested. 
The primary objective of this study is to assess the safety and efficacy of Tranexamic acid (TXA) 
in reducing blood loss and transfusion requirements for patients with osteoporotic hip fractures. 
In addition to assessing blood loss in these patients,  complications associated with TXA use 
would be characterized including systemic (pulmonary embolism, deep venous thrombosis, 
myocardial infarction, stroke) and surgical site (hematoma, infection) events, need for re-
hospitalization or re-operation and 30 day mortality.
2. Background: Describe the background information that led to the plan for this project. 
Provide references to support the expectation of obtaining useful scientific data.
Hip fractures are associated with significant blood loss and a subsequent need for blood 
transfusion. The causes of bleeding are multifactorial, increased fibrinolytic activity being 
one of them.1, 2  The use of allogenic blood products is expensive and is associated with 
increased risk of hemolytic and anaphylactic reactions, post-operative infections1 and 
lengthened hospital stay. Tranexamic acid (TXA) is a simple and inexpensive pharmacologic 
agent that inhibits fibrinolysis and reduced bleeding.1, 2 It has a 44 year history of clinical use 
beginning with patients with symptomatic menorrhagia as well as bleeding prophylaxis in 
hemophiliac patients undergoing tooth extraction
TXA is an antifibrinolytic medication (reduces the destruction of blood clots, thus promoting 
the ability to stop bleeding) that is frequently used to reduce perioperative blood loss, blood 
transfusions and associated costs in major cardiac, vascular, obstetric, and orthopedic 
procedures. It has been used successfully in orthopedics to reduce perioperative blood loss, 
particularly in spine surgery5, 6, 7 total knee and total hip arthroplasty (THA)9,10. Multiple 
recent meta-analyses have found that use of TXA in the setting of total knee arthroplasty 
(TKA) and THA leads to significantly less overall blood loss and lower rates of blood 
transfusion without increasing rates of venous thromboembolism (VTE) or other 
complications11,12.
Osteoporotic hip fractures are at an increased risk for acute blood loss than elective 
orthopaedic surgery patients because they are exposed to a double bleeding insult. Fractures 
bleed and many of these patients sustain their first hit when hematoma forms in their soft

tissues leading to symptomatic anemia. Subsequently these patients sustain additional blood 
loss when they undergo surgery for definitive treatment of their injuries.
Trauma surgeons understand the risk of hemorrhage associated with trauma and routinely 
give TXA to patients who present with high energy injuries.  The CRASH-2 trial was an 
international study which randomized 20,000 bleeding trauma patients to get IV TXA or 
matching placebo upon presentation.  With 99.5% follow up, the authors noted a decreased 
risk of bleeding and death without ill effect.13
Although several previous studies have used IV TXA to reduce blood loss, TXA has proved 
to be an effective antifibrinolytic agent in IV, topical and oral formulations. Oral preparations 
of the drug may be preferred due to their equivalent efficacy and lower cost.14
There are limited data the use of TXA in patients with hip fractures. We propose a double-
blinded, randomized, controlled trial comparing perioperative administration of TXA to 
placebo in the setting of hip fractures. Thus our goal is to examine the safety and efficacy of 
TXA in reducing blood loss and red blood cell requirement for patients with hip fractures at 
the time of hospital admission.
Informed consent will be obtained from the patient or health care proxy upon diagnosis of hip 
fracture by the orthopedic consult resident or research coordinator. At that time, study subjects 
will be randomized to two groups. The two patient groups will include: 
1. 1.95g of oral tranexamic acid upon presentation to the emergency department and again 2 
hours prior to surgery.
2. Placebo tablets in the emergency department and again 2 hours prior to surgery. 
Pharmacy will keep the surgeon blinded to the treatment group that the patient is randomized 
into.  Blood loss following surgery will be evaluated during the entire in-patient stay of the 
study subjects.  Patients will also be surveyed about related complications and/or re-
hospitalizations at their first postoperative office visit (2-3 weeks post-operative).

The study will be a blinded prospective randomized controlled trial, looking at the effect of 
Tranexamic Acid on perioperative blood loss and transfusion rates in patients presenting with 
femoral neck or intertrochanteric femur fractures.  Study subjects will be randomized to receive 
either oral TXA (1.95g) or placebo tablet. One dose will be given by upon presentation to the ED 
and a second dose will be given 2 hours prior to surgery. 
Currently use for tranexamic acid became available on both campuses (SRC and YSC) as of 
6/1/13 for prevention of bleeding in orthopedic joint procedures (total knees and total hips) as 
approved at the May 2013 Pharmacy & Therapeutics (P&T) Committee Meeting. 
Both patients and the treating surgeons will be blinded with regard to placebo vs. treatment until 
completion of the study. All patients will be treated surgically according to the definitive fixation 
required by each specific fracture pattern. These potential surgical interventions include total hip 
arthroplasty, hemiarthroplasty, intramedullary fixation, blade plates, or sliding hip screws in 
accordance with standard of care.
Meticulous hemostasis will be done as per standard of care in any operative case.  
Blood loss will be assessed using the Lisander formula1 where  Estimated blood loss = 
(Blood Volume * Hcti * 0.01) + Vt + Va – (Blood Volume * Hcte * 0.01) where Blood 
Volume is calculated using Nadler’s formula; Hcti is the preoperative haematocrit, Hcte is the 
haematocrit at the end of the hospital stay, Vt is the volume of allogeneic RBC
transfused and Va is the volume of RBC returned by the autotransfusion device. Volumes are 
all in millilitres.
Blood volume is calculated using the Nadler equation (0.006012 x Height3)+(14.6 x 
Weight)+604.
transfusions will be made according to the standard blood transfusion algorithm below. 
Additional data being collected include hospital length of stay, patient demographics 
including ASA class. Complications will be recorded as they occur or at 2 and 6 week follow 
up. Both of these visits will be in-person at their scheduled follow up clinic appointments.

7. How will eligibility be determined, and by whom? 
The primary surgeon and the above residents will determine eligibility in the 
emergency department.  The primary diagnosis for surgery will be used to confirm 
inclusion criteria and then patient history will be conducted to rule out any 
contraindications to tranexamic acid. Subjects will also be excluded if they declined to 
participate.  Surgical consent will be obtained first and within 30 minutes, research 
consent will be obtained after discussion of the research trial versus the standard of 
care.
Surrogate consent will be obtained for subjects unable to provide consent. The consent 
will be obtained in person if the surrogate is present or via a telephone with the help of 
a witness. Re-consenting will also be obtained when applicable. 
8. Risks: Describe the reasonably foreseeable risks, including risks to subject privacy, 
discomforts, or inconveniences associated with subjects participating in the research. 
Most frequently reported adverse effects are minor gastrointestinal symptoms such as nausea 
and vomiting, especially when administered at high dose or injected rapidly.  Higher doses of 
TXA (100 mg/kg or more), much higher than what will be used in this trial (maximum of two 
doses of 1.95g), have been associated with a higher incidence of seizures in cardiac patients 
(TXA crosses the blood–brain barrier and it is believed that a TXA-mediated inhibition of 
glycine receptors may underlie the effect).  It is unclear why most episodes of seizures occur 
during immediate postoperative hours, when levels of intraoperatively administered TXA in 
the serum and cerebrum should already be declining. One possibility is that TXA induces 
modifications (neuroplasticity) in these inhibitory circuits that outlast its pharmacological 
time course. There is higher incidence of TXA-related seizures in patients undergoing open

Adverse Events
An adverse event (AE) is any noxious, unintended, or untoward medical occurrence 
occurring at any dose that may appear or worsen in a subject during the course of a 
study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, 
or any concomitant impairment of the subject’s health, including laboratory test values 
(as specified by the criteria below), regardless of etiology.  Any medical condition that 
was present, prior to study treatment and that remains unchanged or improved should 
not be recorded as an AE.  If there is a worsening of that medical condition, this should 
be considered an AE.  A diagnosis or syndrome should be recorded as an AE rather 
than the individual signs or symptoms of the diagnosis or syndrome.
All AEs will be recorded by the Investigator(s) from signature of the informed consent 
form through 6 week post-operative period. AEs will be recorded on the data collection 
form. All AEs will be followed until resolved. Any AEs uncovered during routine 
postoperative care visits or review of the EMR will also be reported for study purposes.
Project specific AEs Exempt From Reporting
Certain adverse events would be expected to occur in hip fracture patients regardless of the use of 
the investigational product TXA.  Therefore, within the post-surgical period, the following adverse 
events will be excluded from collection unless they are of a severity or frequency greater than 
would be expected for this post-surgical patient population.

Abnormal laboratory values defined as adverse events
An abnormal laboratory value is considered to be an AE if the laboratory abnormality is 
characterized by any of the following:

Requires treatment, modification/interruption of study medication dose, or any other 
therapeutic intervention.

Is judged by the investigator to be of significant clinical importance.
If a laboratory abnormality is one component of a diagnosis or syndrome, then only the diagnosis 
or syndrome would be recorded. If the abnormality was not a part of a diagnosis or syndrome, then 
the laboratory abnormality would be recorded as the AE.
Serious adverse event
A serious adverse event (SAE) is any AE which:

Results in death

Is life-threatening (i.e., in the opinion of the investigator the subject is at immediate risk of 
death from the AE)

Requires inpatient hospitalization or prolongation of existing hospitalization

Results in persistent or significant disability/incapacity (a substantial disruption of the 
subject’s ability to conduct normal life functions)

Is a congenital anomaly/birth defect

Constitutes an important medical event
Important medical events are defined as those occurrences that may not be immediately life 
threatening or result in death, hospitalization, or disability, but may jeopardize the subject or 
require medical or surgical intervention to prevent one of the other outcomes listed above.  Medical 
and scientific judgment should be exercised in deciding whether such an AE should be considered 
serious.
Events not considered to be SAEs are hospitalizations which: were planned before entry into the 
clinical study; are for elective treatment of a condition unrelated to the studied indication or its 
treatment; occur on an emergency outpatient basis and do not result in admission (unless fulfilling 
other criteria above); are part of the normal treatment or monitoring of the studied indication and 
are not associated with any deterioration in condition.
For each SAE, the investigator will provide information on severity, start and stop dates, 
relationship to study medication, action taken regarding study medication, and outcome.

Classification of severity
The severity of adverse events (AEs) will be graded on a scale of 1 to 5 according to the National 
Cancer Institute (NCI) Common Terminology Criteria for Adverse Events   ([The NCI Common 
Terminology Criteria for Adverse Events, Version 4.0 [NCI CTCAE]. The NCI CTCAE can be 
viewed on-line at the following NCI web site:
http://ctep.cancer.gov/reporting/ctc.html
If a specific event is not included in the NCI CTCAE toxicity scale, the following scale will be 
used to grade the event:
Grade
Definition
1
Mild   Awareness of sign, symptom, or event, usually transient, requiring 
no special treatment and generally not interfering with usual daily activities
2
Moderate  Discomfort that causes interference with usual activities; usually 
ameliorated by basic therapeutic maneuvers
3
Severe   Incapacitating with inability to do usual activities or significantly 
affects clinical status and warrants intervention. Hospitalization may or may 
not be required 
4 
Life-threatening   Immediate risk of death; requires hospitalization and 
clinical intervention. 
5
Death
Classification of Relationship/Causality of adverse events (AE/SAE) to study drug
The investigator will determine the relationship between the administration of study drug and the 
occurrence of an AE/SAE as not suspected or suspected as defined below:
Not suspected:
The temporal relationship of the adverse event to study drug administration 
makes a causal relationship unlikely or remote, or other medications, 
therapeutic interventions, or underlying conditions provide a sufficient 
explanation for the observed event
Suspected:
The temporal relationship of the adverse event to study drug administration 
makes a causal relationship possible, and other medications, therapeutic 
interventions, or underlying conditions do not provide a sufficient explanation 
for the observed event. 
Unknown
The temporal relationship of the adverse event to study drug administration 
makes a causal relationship unable to determine or unknown
Monitoring and reporting of adverse events
All subjects will be monitored for AEs between the signing of the informed consent and 6 weeks 
postop. Assessments may include monitoring of any or all of the following parameters: the 
subject’s clinical symptoms; laboratory, pathological, radiological, or surgical findings; physical

examination findings; or other appropriate tests and procedures.  Any AEs uncovered during 
routine postoperative care visits will be reported for study purposes.
9. Minimizing Risks: Describe the manner in which the above-mentioned risks will be 
minimized.
The above risks are more pronounced in cardiac surgery patients, not orthopaedic surgery 
patients. Nonetheless, the patients will be carefully monitored intraoperatively as well as 
postoperatively. They will be given an antiemetic if necessary and started on proton-pump 
inhibitor (PPI) if indicated.  
Only the listed investigators will have access to the data, and no access will be given to anyone 
not involved in the collection and analysis of this data. Data will be kept in an excel spreadsheet 
and stored on encrypted computer without patient names or dates of birth. All data will be 
destroyed when the manuscript is published
10. Data and Safety Monitoring Plan: Include an appropriate Data and Safety Monitoring Plan 
(DSMP) based on the investigator’s risk assessment stated below. (Note: the HIC will make 
the final determination of the risk to subjects.) For more information, see the Instructions, 
page 24.
a. 
What is the investigator’s assessment of the overall risk level for subjects 
participating in this study? Above Minimal Risk
b.
If children are involved, what is the investigator’s assessment of the overall risk 
level for the children participating in this study? No Subjects <18 years old
c.
Include an appropriate Data and Safety Monitoring Plan. Examples of DSMPs are  
 available here http://www.yale.edu/hrpp/forms-templates/biomedical.html  for
i. Minimal risk
ii. Greater than minimal
Greater Than Minimal Risk DSMP
1. Personnel responsible for the safety review and its frequency:
The principal investigator will be responsible for monitoring the data, assuring protocol 
compliance, and conducting the safety reviews at the specified frequency, which must be 
conducted at a minimum of every 6 months (including when reapproval of the protocol is 
sought).  During the review process, the principal investigator  will evaluate whether the study 
should continue unchanged, require modification/amendment, or close to enrollment. Either the

Page 20 of 39
principal investigator, the IRB or Yale Cancer Center Data and Safety Monitoring Committee 
(DSMC) have the authority to stop or suspend the study or require modifications.
2. The risks associated with the current study are deemed greater than minimal for the 
following reasons: 
1. We do not view the risks associated with the tranexamic acid administration as minimal 
risks.
Although we have assessed the proposed study as one of greater than minimal risk, the potential 
exists for anticipated and/or unanticipated adverse events, serious or otherwise, to occur since it 
is not possible to predict with certainty the absolute risk in any given individual or in advance of 
first-hand experience with the proposed study methods. Therefore, we provide a plan for 
monitoring the data and safety of the proposed study as follows:
3. Attribution of Adverse Events:
Adverse events will be monitored for each subject participating in the study and attributed to the 
study procedures / design by the principal investigator Michael P. Leslie, DO according to the 
following categories:
a.) Definite: Adverse event is clearly related to investigational procedures(s)/agent(s).
b.) Probable: Adverse event is likely related to investigational procedures(s)/agent(s).
c.) Possible: Adverse event may be related to investigational procedures(s)/agent(s).
d.) Unlikely: Adverse event is likely not to be related to the investigational 
procedures(s)/agent(s).
e.) Unrelated: Adverse event is clearly not related to investigational procedures(s)/agent(s).
4. Plan for Grading Adverse Events:
The following scale will be used in grading the severity of adverse events noted during the study:
1. Mild adverse event
2. Moderate adverse event
3. Severe 
5. Plan for Determining Seriousness of Adverse Events:
Serious Adverse Events:
In addition to grading the adverse event, the PI will determine whether the adverse event meets 
the criteria for a Serious Adverse Event (SAE).  An adverse event is considered serious if it 
results in any of the following outcomes:
1. Death;
2. A life-threatening experience in-patient hospitalization or prolongation of existing 
hospitalization; 
3. A persistent or significant disability or incapacity;

APPROVED BY THE YALE UNIVERSITY IRB 12/21/2016 VALID THROUGH 12/20/2017
Page 21 of 39
4. A congenital anomaly or birth defect; OR
5. Any other adverse event that, based upon appropriate medical judgment, may jeopardize 
the subject’s health and may require medical or surgical intervention to prevent one of 
the other outcomes listed in this definition. 
An adverse event may be graded as severe but still not meet the criteria for a Serious Adverse 
Event.  Similarly, an adverse event may be graded as moderate but still meet the criteria for an 
SAE.  It is important for the PI to consider the grade of the event as well as its “seriousness” 
when determining whether reporting to the IRB is necessary.
6. Plan for reporting UPIRSOs (including Adverse Events) to the IRB
The principal investigator will report the following types of events to the IRB: 
Any incident, experience or outcome that meets ALL 3 of the following criteria:
Is unexpected (in terms of nature, specificity, severity, or frequency) given (a) the 
research procedures described in the protocol-related documents, such as the IRB-
approved protocol and informed consent document and (b) the characteristics of the 
subject population being studied; AND 
Is related or possibly related to participation in the research (possibly related means there 
is a reasonable possibility that the incident, experience, or outcome may have been 
caused by the procedures involved in the research); AND
Suggests that the research places subjects or others at greater risk of harm (including 
physical, psychological, economic, legal, or social harm) than was previously known 
or recognized.
Unanticipated Problems Involving Risks to Subjects or Others (UPIRSOs) may be medical or 
non-medical in nature, and include – but are not limited to – serious, unexpected, and related 
adverse events and unanticipated adverse device effects.  Please note that adverse events are 
reportable to the IRB as UPIRSOs only if they meet all 3 criteria listed above.
These UPIRSOs/SAEs will be reported to the IRB in accordance with IRB Policy 710, using the 
appropriate forms found on the website. All related events involving risk but not meeting the 
prompt reporting requirements described in IRB Policy 710 should be reported to the IRB in 
summary form at the time of continuing review. If appropriate, such summary may be a simple 
brief statement that events have occurred at the expected frequency and level of severity as 
previously documented.  In lieu of a summary of external events, a current DSMB report can be 
submitted for research studies that are subject to oversight by a DSMB (or other monitoring 
entity that is monitoring the study on behalf of an industry sponsor).
7. Plan for reporting adverse events to co-investigators on the study, as appropriate the 
protocol’s research monitor(s), e.g., industrial sponsor, Yale Cancer Center Data and 
Safety Monitoring Committee (DSMC), Protocol Review Committee (PRC), DSMBs, study 
sponsors, funding and regulatory agencies, and regulatory and decision-making bodies.

 Yale Cancer Center Data and Safety Monitoring Committee (DSMC)
 Other Data Safety Monitoring Board (DSMB) or Committee (DSMC)
The principal investigator Michael P. Leslie, DO will conduct a review of all adverse events 
upon completion of every study subject. The principal investigator will evaluate the frequency 
and severity of the adverse events and determine if modifications to the protocol or consent form 
are required.
d. For multi-site studies for which the Yale PI serves as the lead investigator:
i. How will adverse events and unanticipated problems involving risks to subjects or 
others be reported, reviewed and managed?
ii. What provisions are in place for management of interim results?
iii. What will the multi-site process be for protocol modifications?
11. Statistical Considerations: Describe the statistical analyses that support the study design. 
Desai cites a 39.5% rate of transfusion with fixation of hip fractures1, which is similar to the rate 
of transfusion we have observed among our own patient population. The use of TXA has been 
associated with a decreased risk ratio of transfusion of 2.51 for those patients receiving oral TXA 
for total hip replacement, a similar type of procedure.
Based upon these numbers:
80% power
a=0.05 
two-tailed test
Likelihood of transfusion: 39.5%
Risk ratio with TXA is 2.51

Tranexamic acid (TXA) is a synthetic antifibrinolytic drug released in the 1970s. Has ten times 
the potency of Σ-amino-caproic acid (EACA) – the prototypical antifibrinolytic [7]. 
Mechanism of action - synthetic derivative of the amino acid lysine (competitive blockade of the 
lysine- binding sites of plasminogen, plasmin, and tissue plasminogen activator). The reversible 
blockade impedes fibrinolysis and blood-clot degradation. Plasmin inhibition by TXA may also 
help prevent platelet degradation.
Antifibrinolytic agents are widely used in major surgery to prevent fibrinolysis and reduce 
surgical blood loss. Numerous studies support the premise that TXA reduces blood loss, 
statistically significant reduction in transfusion (by one – third) rates and reduces the financial 
cost of surgery. Kogoma 2009 systematic review of randomized trials on MEDLINE, EMBASE, 
CINAHL and the Cochrane databases reported the efficacy of antifibinolytic agents in reducing 
bleeding and transfusion in patients undergoing total hip or total knee replacements who received 
a prophylactic dose of antifibrinolytic agents.
Very cost effective - Guerriero 2011 reported that administration of TXA within three hours of 
injury to bleeding trauma patients has been estimated to save 755 life years (LYs) per 1000 
trauma patients in the UK, and the incremental cost of giving TXA versus not giving TXA was 
estimated at USD 48,002 in the UK, equivalent of a cost of around USD 64 per life-year saved.
Tranexamic acid reduces all-cause mortality in bleeding trauma patients, with no apparent 
increase in the risk of vascular occlusive events. This conclusion is based on the results of the 
CRASH-2 2010 trial which recruited 20,211 bleeding trauma patients from 274 hospitals in 40 
countries.

excessive bleeding
 - Dental surgery
Concerns
-
TXA does not increase the risk of thromboembolic complications such as deep-vein 
thrombosis, pulmonary embolism, thrombotic cerebral vascular accident, or myocardial 
infarction 
-
Concerns in hip and knee arthroplasty have been perceived increased risk of 
thromboembolism in a high-risk predisposed population. However, most recent reports have 
found no difference in the rates of deep vein thrombosis and pulmonary embolism between 
patients receiving tranexamic acid and comparison cohorts.
-
Recent large Cochrane review of over 25,000 patients (Henry 2011), the use of TXA or 
EACA was not associated with an increased risk of mortality, myocardial infarction, deep 
vein thrombosis, stroke, incidence of renal dysfunction
-
Common misconception is that these drugs are procoagulants and that they will increase 
blood clotting. The drugs do not alter blood clotting, but instead slow dissolution of blood 
clots. Sites where clots have formed will therefore remain or enlarge, but spontaneous 
formulation of clots should not occur
Known risks/adverse events
-
Most frequently reported adverse effects are minor gastrointestinal symptoms such as 
nausea and vomiting, especially when administered at high dose or injected rapidly. 
-
Higher doses of TXA (100 mg/kg or more), much higher than what will be used in this trial 
(less than 30mg/kg), have been associated with a higher incidence of seizures in cardiac 
patients (TXA crosses the blood–brain barrier and it is believed that a TXA-mediated 
inhibition of glycine receptors may underlie the effect).  
o
Unclear why most episodes of seizures occur during immediate postoperative hours, 
when levels of intraoperatively administered TXA in the serum and cerebrum should 
already be declining.
o
Possibility is that TXA induces modifications (neuroplasticity) in these inhibitory 
circuits that outlast its pharmacological time course
o
Higher incidence of TXA-related seizures in patients undergoing open heart 
procedures may relate to disruption of BBB integrity by cerebral emboli, which 
known to be much more prevalent during open-heart procedures versus coronary 
artery bypass grafting
-
Persistent atrial fibrillation
-
Increased risk of seizures and with renal complications following their use in cardiac 
surgery.
-
May increase risk of disseminated intravascular coagulation (DIC). 
-
Need for caution in the use of these agents in patients with hematological malignancies as

they are at increased risk of DIC 
Data addressing dosage(s)
-
Several systematic reviews have investigated the dosing regimen 
-
Total dose of TXA used in the trials ranged from 5.5 to 300 mg/kg. 
-
Median dose was 22 mg/kg, with majority of trials (70 per cent) using total dose of 30mg/kg 
or less. 
-
Data suggested effect of TXA on blood loss did not vary over the dose range assessed 
-
Total dose of 1 g likely to be sufficient for most adults, 
-
Typical loading dosing for tranexamic acid is 10 mg/kg and this usually followed by 
continuous infusion of 1 mg/ kg/h for 6 hours. 
Interval(s)
-
Half life of TXA ~ 80 min, provided there is normal renal function. One dose (oral) will be 
given on arrival in the ED and a second dose will be given at the time of surgical incision. 
Route(s) of administration as described in previous studies:
-
Oral
-
Topical :
o
Plasma concentrations following the topical application of TXA are less than one 
tenth of the level after IV administration
o
Because there is less systemic absorption, the direct application of TXA to the 
bleeding surface has potential to reduce bleeding with minimal systemic effects
o
Clinical scenarios: epistaxis, traumatic hyphemia, gastrointestinal bleeding, surgical 
bleeding and uterine bleeding
o
Administered in saline solution (3 grams of TXA) in 100 cc of normal saline) 
directly on to operative site, either by pouring or spraying into the surgical wound or 
as a mouthwash in the dental surgery
o
Gel, Spray, mouth wash
-
Intravenous (majority)
-
Intra-articular injection (TKA,THA) – 
o
One study looked at solution containing 250-mg (5 ml) or 500-mg (10 ml) of TXA 
which was added with physiologic saline to create a total volume of 25 ml. 
o
Demonstrated that intra-articular application with low-dosage TXA, as 250 and 500 
mg, was effective for reducing postoperative blood loss

be obtained, including parental permission or surrogate permission and the steps taken to ensure 
subjects’ independent decision-making. 
The process of consent will be confidential and discussed in a private setting, and 
the patient will have time to think or discuss with family member(s).  The 
informed consent form will be used to explain the risks and benefits of study 
participation to the subject in simple terms before the subject will be entered into 
the study. The informed consent form contains a statement that the consent is 
freely given, that the subject is aware of the risks and benefits of entering the 
study, and that the subject is free to withdraw from the study at any time. Written 
consent must be given by the subject and/or legal representative, after the receipt 
of detailed information on the study. The Investigator is responsible for ensuring 
that informed consent is obtained from each subject or legal representative and 
for obtaining the appropriate signatures and dates on the informed consent 
document prior to the performance of any protocol procedures and prior to the 
administration of study medication. The Investigator will provide each subject 
with a copy of the signed and dated consent form and will document in the 
subject’s source notes that informed consent was given.

 No
c. Why would the research be impracticable to conduct without the waiver? 
d. Where appropriate, how will pertinent information be returned to, or shared with 
subjects at a later date? 
SECTION VIII: PROTECTION OF RESEARCH SUBJECTS
    Confidentiality & Security of Data:
a.    What protected health information (medical information along with the HIPAA identifiers) 
about subjects will be collected and used for the research?   
Medical record numbers, social security numbers, telephone numbers, medical 
history, age, date of birth.
       
b.    How will the research data be collected, recorded and stored? 
Research data will be collected by interviewing the subject or the power of attorney, 
questionnaires. The data will be recorded and stored electronically on a password-
protected computer. The research data will also be stored on a flash drive, portable 
hard drive and kept locked in the PI’s office.
c.    How will the digital data be stored? 
 CD  
 DVD  X  Flash Drive  X Portable Hard   
       Drive  X Secured Server  X  Laptop Computer  
 Desktop Computer  
 Other
d.    What methods and procedures will be used to safeguard the confidentiality and security of    
the identifiable study data and the storage media indicated above during and after the subject’s 
participation in the study?
The PI’s password-protected computer will store the collected data and an encrypted 
portable hard drive and a flash drive will be used for data transport. These materials 
will be stored in the PI’s locked office.

Do all portable devices contain encryption software? X Yes   
 No
         If no, see http://hipaa.yale.edu/guidance/policy.html
 
e.
What will be done with the data when the research is completed? Are there plans to destroy     
the identifiable data? If yes, describe how, by whom and when identifiers will be destroyed. If 
no, describe how the data and/or identifiers will be secured.
Upon the completion of this study, collected data will be saved in an encrypted portable 
hard drive stored in a locked cabinet in the PI’s locked office for use for possible follow-
up studies. After all studies have been completed, all stored data will be destroyed by the 
PI using secure erase. 
f.   Who will have access to the protected health information (such as the research sponsor, the  
investigator, the research staff, all research monitors, FDA, Yale Cancer Center Data and Safety 
Monitoring Committee (DSMC), SSC, etc.)? (please distinguish between PHI and de-identified 
data) 
The research team at Yale New Haven Hospital  will be the only ones to have access to the de-
identified information.
g.   If appropriate, has a Certificate of Confidentiality been obtained? N/A
h.   Are any of the study procedures likely to yield information subject to mandatory reporting   
requirements? (e.g. HIV testing – reporting of communicable diseases; parent interview -incidents 
of child abuse, elderly abuse, etc.). Please verify to whom such instances will need to be reported.   
NO
SECTION IX: POTENTIAL BENEFITS
Potential Benefits: Identify any benefits that may be reasonably expected to result from the 
research, either to the subject(s) or to society at large. (Payment of subjects is not considered a 
benefit in this context of the risk benefit assessment.) 
The potential benefits include decreased morbidity and possible mortality in intertrochanteric 
femur fractures. With decreased bleeding preoperatively and postoperatively, the 
likelihood of wound problems, infection, or post-operative hematomas will be much less.  
In addition, the morbidity and mortality from a allogeneic transfusion will be decreased if 
TXA is used.  Lastly, health care costs will be decreased, as transfusions are costly 
interventions, compared to the cost of TXA  ($41 per dose vs > $400 for an allogeneic 
transfusion of packed red blood cells.

         SECTION X: RESEARCH ALTERNATIVES AND ECONOMIC CONSIDERATIONS
1.     Alternatives: What other alternatives are available to the study subjects outside of the research?
2. 
Payments for Participation (Economic Considerations): Describe any payments that will be 
made to subjects, the amount and schedule of payments, and the conditions for receiving this 
compensation.   None
2. Costs for Participation (Economic Considerations): Clearly describe the subject’s costs 
associated with participation in the research, and the interventions or procedures of the 
study that will be provided at no cost to subjects.    
  
The cost to the patient will be zero. The drug itself costs $17.00.
4.
In Case of Injury: This section is required for any research involving more than minimal risk.
a.     Will medical treatment be available if research-related injury occurs? 
The patient will have full access to medical care while in the hospital and post 
operatively. 
b. Where and from whom may treatment be obtained? 
The attending physician (PI) and any other consulting physicians that are needed.
c.
Are there any limits to the treatment being provided?  NO
d. Who will pay for this treatment? 
The subject or the subject insurance is responsible for the financial cost. 
e.     How will the medical treatment be accessed by subjects?
Through YNNH in the post operative period
