 1.0           BACKGROUND AND RATIONALE 
1.1           Disease Background  
Leiomyomata are the most common tumors of the uterus. Though the majority of women with fibroids are 
asymptomatic, a significant portion suffer symptoms including abnormal bleeding, pain, pressure and 
abdominal distention (1). Submucosal and large intramural fibroids have also been shown to impair 
fertility. Many women seek treatment for fibroids but desire to retain their uterus, whether to preserve 
future fertility or for other personal reasons. Myomectomy is a curative treatment that allows for uterine 
preservation but can come at the risk of substantial intraoperative blood loss. 
 
Studies have assessed the utility of GnRH, vasopressin, peri-cervical tourniquet, misoprostol and 
oxytocin, among others, in reducing intraoperative blood loss (2). Findings from small randomized trials 
demonstrate significantly lower intraoperative blood loss among women who receive preoperative 
misoprostol compared to those who receive placebo (4, 6, 7). Other research fails to demonstrate a 
difference in blood loss following preoperative misoprostol (8) and cites methodologic flaws with existing 
studies (5). Additionally, no randomized controlled trial has been done in a U.S. population. A double-
blinded, randomized, placebo-controlled trial at a tertiary care center in a major U.S. city is an ideal 
setting for evaluation of this research question. 
 
The aim of this study is to assess the impact of preoperative buccal misoprostol on intraoperative blood 
loss and clinical outcomes related to blood loss (blood transfusion, protracted hospital stay). Defining the 
relationship between misoprostol and blood loss during myomectomy would provide insight into the 
mechanism of uterine contraction and hemostasis and inform optimal preoperative clinical management 
of patients undergoing this common and potentially morbid procedure. 
1.2           Study Agent(s)/Devices Background and Associated Known Toxicities 
Misoprostol is an analogue of prostaglandin E1 initially developed for treatment of NSAID induced peptic 
ulcers, which is currently used in a variety of contexts in the field of obstetrics and gynecology including in 
the FDA approved regimen for medical abortion, cervical ripening, and treatment of postpartum 
hemorrhage. In non-pregnant women, misoprostol has been widely described for use in cervical 
preparation prior to hysteroscopy, intrauterine device insertion, and endometrial biopsy. 
 
Multiple routes of administration have been studied including oral, sublingual or buccal, rectal and vaginal 
administration with peak plasma concentrations less than 30 minutes after administration via the oral or 
sublingual route. Systemic bioavailablity of sublingual misoprostol is significantly greater than with orally 
or vaginally administered misoprostol however overall plasma concentrations persist for at least 6 hours 
at higher concentrations when administered vaginally. Potent uterotonic activity is noted as a result of 
increased intracellular calcium activating myosin light-chain kinase. 
 
Adverse effects of misoprostol vary and include abnormal vaginal bleeding, lower abdominal pain and 
cramping, fever or shivering, nausea, vomiting and diarrhea with more uterine cramping and vaginal 
bleeding associated with vaginal administration (3). 
 
Prior studies evaluating misoprostol effect on intraoperative blood loss at time of either an abdominal and 
laparoscopic myomectomy have used a single dose of 400mcg misoprostol administered vaginally or 
rectally pre-procedure and have found a significant decrease in blood loss. 400mcg is the standard dose 
used for the majority of gynecologic applications and appears to be well tolerated (4-9). There are no 
additional risks to study participants adding laparoscopic surgery to this study.

1.3           Other Agents/Devices 
Placebo will be 100mg vitamin B6 (pyridoxine) tablets (see Section 8.2).  
 
1.4           Rationale 
Abdominal myomectomy is a common procedure that comes with risks of significant morbidity, including 
intraoperative blood loss at time of abdominal myomectomy as well as numerous postoperative 
complications including an up to 20% requirement for transfusion and 2% reported conversion to 
hysterectomy. The significant morbidity associated with this procedure has led to studies evaluating 
multiple interventions to reducing bleeding during myomectomy. A systematic review of the interventions 
to reduce blood loss at time of myomectomy found significant reductions in blood loss with use of vaginal 
misoprostol however included only one randomized controlled trial (2). Since this time, other studies have 
been done that reproduce these findings (6, 7), though sample size in these trials is small and results are 
inconsistent (8). This study would augment existing data by employing a larger sample size and double-
blinded design in a U.S. population. This study would also assess the impact of a route of misoprostol 
administration that is less invasive for patients (buccal instead of vaginal or rectal) but offers a similar 
pharmokinetic profile. Outcomes assessed include estimated blood loss, need for transfusion, prolonged 
hospitalization, change in postoperative hemoglobin level from preoperative baseline.

11 
subject may be considered lost to follow-up.  
6.0     
Response Criteria 
Clinically-documented intraoperative blood loss.  
 
6.1   Safety/Tolerability 
All patients will be closely monitored by physician and nursing staff in the operating room and post-
operative recovery area for the full duration of action of the active medication. Misoprostol is largely 
considered a safe, well-studied medication (10). The risk profile may be even more favorable when a 
single dose of misoprostol is administered (11).  
 
The placebo medication, pyridoxine (Vitamin B6), is a safe nutritional supplement with no known side 
effects of a one-time dose. Additionally, it is absorbed in the jejunum such that absorption when buccally 
administered (12). 
7.0     
ADVERSE EVENTS 
7.1      Experimental Therapy 
For the most recent safety update, please refer to the current Investigator’s Brochure or Study Agent 
Prescribing Information. The following information is taken from the FDA website (10). 
7.1.1      Contraindications 
Pregnancy, history of allergy to prostaglandins or Vitamin B6. 
7.1.2   Special Warnings and Precautions for Use 
In pregnant women, cytotec can cause birth defects, abortion or premature birth. Uterine rupture has 
been reported when cytotec has been administered to pregnant women to induce labor or to induce 
abortion beyond the 8th week of pregnancy. Patients should be advised that cytotec should not be given 
to others due to its abortifacient properties. 
Cytotec may be prescribed if the patient: 
• has had a negative serum pregnancy test within 2 weeks prior to beginning therapy. 
• is capable of complying with effective contraceptive measures. 
• has received both oral and written warnings of the hazards of misoprostol, the risk of possible 
contraception failure, and the danger to other women of childbearing potential should the drug be taken 
by mistake. 
• will begin Cytotec only on the second or third day of the next normal menstrual period. 
WARNING for off-label uses: 
For hospital use only if misoprostol were to be used for cervical ripening, induction of labor, or for the 
treatment of serious post-partum hemorrhage, which are outside of the approved indication. 
7.1.3   Interaction with other medications 
Misoprostol is a renally-cleared medication and does not affect the hepatic mixed function oxidase 
(cytochrome P-450) enzyme systems in animals. 
 
Drug interaction studies between misoprostol and several nonsteroidal anti-inflammatory drugs showed 
no effect on the kinetics of ibuprofen or diclofenac, and a 20% decrease in aspirin AUC, not thought to 
be clinically significant. Pharmacokinetic studies also showed a lack of drug interaction with antipyrine 
and propranolol when these drugs were given with misoprostol. Misoprostol given for 1 week had no 
effect on the steady state pharmacokinetics of diazepam when the two drugs were administered 2 hours 


STU00091259

12 
apart. The serum protein binding of misoprostol acid is less than 90% and is concentration-independent in 
thetherapeutic range. 
 
7.1.4   Adverse Reactions 
The FDA reports the following possible side effects with the active medication (Misoprostol):  
 
Gastrointestinal: In subjects receiving Cytotec 400 or 800 mcg daily in clinical trials, the most frequent 
gastrointestinal adverse events were diarrhea and abdominal pain. The incidence of diarrhea at 800 mcg 
in controlled trials in patients on NSAIDs ranged from 14-40% and in all studies (over 5,000 patients) 
averaged 13%. Abdominal pain occurred in 13-20% of patients in NSAID trials and about 7% in all 
studies, but there was no consistent difference from placebo. 
 
Diarrhea was dose related and usually developed early in the course of therapy (after 13 days), usually 
was self-limiting (often resolving after 8 days), but sometimes required discontinuation of Cytotec (2% 
of the patients). Rare instances of profound diarrhea leading to severe dehydration have been reported. 
 
Patients with an underlying condition such as inflammatory bowel disease, or those in whom 
dehydration, were it to occur, would be dangerous, should be monitored carefully if Cytotec is 
prescribed. 
 
Gynecological: Women who received Cytotec during clinical trials reported the following gynecological 
disorders: spotting (0.7%), cramps (0.6%), hypermenorrhea (0.5%), menstrual disorder (0.3%) and 
dysmenorrhea (0.1%). Postmenopausal vaginal bleeding may be related to Cytotec administration. If it 
occurs, diagnostic workup should be undertaken to rule out gynecological pathology. Research studies in 
obstetrics and gynecology also identify possible side effects of diarrhea, fever and shivering (4,6,7). 
 
Elderly: There were no significant differences in the safety profile of Cytotec in approximately 500 ulcer 
patients who were 65 years of age or older compared with younger patients. 
 
Additional adverse events which were reported are categorized as follows: 
 
In clinical trials, the following adverse reactions were reported by more than 1% of the subjects receiving 
Cytotec and may be causally related to the drug:  nausea (3.2%), flatulence, (2.9%), headache (2.4%), 
dyspepsia (2.0%), vomiting (1.3%), and constipation (1.1%). However, there were no significant 
differences between the incidences of these events for Cytotec and placebo.  
 
Causal relationship unknown: The following adverse events were infrequently reported. Causal 
relationships between Cytotec and these events have not been established but cannot be excluded: 
Body as a whole: aches/pains, asthenia, fatigue, fever, rigors, weight changes. 
Skin: rash, dermatitis, alopecia, pallor, breast pain. 
Special senses: abnormal taste, abnormal vision, conjunctivitis, deafness, tinnitus, earache. 
Respiratory: upper respiratory tract infection, bronchitis, bronchospasm, dyspnea, pneumonia, epistaxis. 
Cardiovascular: chest pain, edema, diaphoresis, hypotension, hypertension, arrhythmia, phlebitis, 
increased cardiac enzymes, syncope. 
Gastrointestinal: GI bleeding, GI inflammation/infection, rectal disorder, abnormal hepatobiliary 
function, gingivitis, reflux, dysphagia, amylase increase. 
Hypersensitivity: anaphylaxis

7.2           Adverse Event Monitoring 
Adverse event data collection and reporting, which are required as part of every clinical trial, are done to 
ensure the safety of Subjects enrolled in the studies as well as those who will enroll in future studies 
using similar agents. Adverse events are reported in a routine manner at scheduled times during a trial. 
Additionally, certain adverse events must be reported in an expedited manner to allow for optimal 
monitoring of patient safety and care. 
  
All patients experiencing an adverse event, regardless of its relationship to study drug/device, will be 
monitored until: 
Ø  the adverse event resolves or the symptoms or signs that constitute the adverse event return to 
baseline; 
Ø  any abnormal laboratory values have returned to baseline; 
Ø  there is a satisfactory explanation other than the study drug for the changes observed; or 
Ø  death. 
7.3           Definitions 
7.3.1 Definition of Adverse Event 
An adverse event (AE) is any untoward medical occurrence in a patient receiving study treatment and 
which does not necessarily have a causal relationship with this treatment. An AE can therefore be any 
unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease 
temporally associated with the use of an experimental intervention, whether or not related to the 
intervention. 
7.3.2 Severity of Adverse Events 
The severity of an AE is graded as follows: 
Mild (grade 1): the event causes discomfort without disruption of normal daily activities. 
Moderate (grade 2): the event causes discomfort that affects normal daily activities. 
Severe (grade 3): the event makes the patient unable to perform normal daily activities or significantly 
affects his/her clinical status. 
Life-threatening (grade 4): the patient was at risk of death at the time of the event. 
Fatal (grade 5): the event caused death. 
7.3.3 Serious Adverse Events 
A “serious” adverse event is defined in regulatory terminology as any untoward medical occurrence that: 
7.3.3.1         Results in death. 
If death results from (progression of) the disease, the disease should 
be reported as event (SAE) itself. 
7.3.3.2         Is life-threatening. 
(the patient was at risk of death at the time of the event; it does not 
refer to an event that hypothetically might have caused death if it 
were more severe). 


STU00091259 
________________________________________________________________________ 
14 
7.3.3.3         Requires in-patient hospitalization or prolongation of existing 
hospitalization for ≥ 24 hours. 
7.3.3.4         Results in persistent or significant disability or incapacity. 
7.3.3.5         Is a congenital anomaly/birth defect 
7.3.3.6         Is an important medical event 
Any event that does not meet the above criteria, but that in the 
judgment of the investigator jeopardizes the patient, may be 
considered for reporting as a serious adverse event. The event may 
require medical or surgical intervention to prevent one of the 
outcomes listed in the definition of “Serious Adverse Event“. 
For example: allergic bronchospasm requiring intensive treatment in 
an emergency room or at home; convulsions that may not result in 
hospitalization; development of drug abuse or drug dependency. 
7.4           Steps to Determine If an Adverse Event Requires Expedited Reporting 
Step 1:       
Identify the type of adverse event   
  
Step 2: Grade the adverse event 
  
Step 3: Determine whether the adverse event is related to the protocol therapy 
Attribution categories are as follows: 
-        Definite – The AE is clearly related to the study treatment. 
-        Probable – The AE is likely related to the study treatment. 
-        Possible – The AE may be related to the study treatment. 
-                   Unrelated – The AE is clearly NOT related to the study treatment. 
Note: This includes all events that occur within 30 days of the last dose of protocol treatment. Any event 
that occurs more than 30 days after the last dose of treatment and is attributed (possibly, probably, or 
definitely) to the agent(s) must also be reported accordingly. 
  
Step 4:          
Determine the prior experience of the adverse event. 
Expected events are those that have been previously identified as resulting from administration of the 
agent. An adverse event is considered unexpected, for expedited reporting purposes only, when either 
the type of event or the severity of the event is not listed in: 
·    
the current known adverse events listed in the Agent Information Section of this protocol; 
·    
the drug package insert; 
·    
the current Investigator’s Brochure 
7.5         Reporting Requirements for Adverse Events 
7.5.1      Expedited Reporting 
·         The Principal Investigator must be notified within 24 hours of learning of 
any serious adverse events, regardless of attribution, occurring during the 
study or within 30 days of the last administration of the study drug. 
·         The office of Risk Management and the IRB must be notified within 10 
business days of “any unanticipated problems involving risk to subjects or others” 
(UPR/UPIRSO). 
Insert your local requirements below: 
The following events meet the definition of UPR: 


STU00091259 
________________________________________________________________________ 
15 
1.     Any serious event (injuries, side effects, deaths or other problems), 
which in the opinion of the Principal Investigator was unanticipated, 
involved risk to subjects or others, and was possibly related to the 
research procedures. 
2.     Any serious accidental or unintentional change to the IRB-
approved protocol that alters the level of risk. 
3.     Any deviation from the protocol taken without prior IRB review to 
eliminate apparent immediate hazard to a research subject. 
4.     Any new information (e.g., publication, safety monitoring report, 
updated sponsor safety report), interim result or other finding that 
indicates an unexpected change to the risk/benefit ratio for the 
research. 
5.     Any breach in confidentiality that may involve risk to the subject or 
others. 
6.     Any complaint of a subject that indicates an unanticipated risk or 
that cannot be resolved by the Principal Investigator. 
·         For IND/IDE trials: The FDA should be notified within 7 business days of 
any unexpected fatal or life-threatening adverse event with possible 
relationship to study drug, and 15 business days of any event that is 
considered: 1) serious, 2) unexpected, and 3) at least possibly related to 
study participation. 
7.5.2      Routine Reporting 
·         All other adverse events- such as those that are expected, or are unlikely 
or definitely not related to the study participation- are to be reported 
annually as part of regular data submission. 
7.6           Unblinding Procedures 
Unblinding to occur in the case of serious morbidity or life-threatening illness that may be reasonably 
attributable to administration of misoprostol, including but not limited to admission to the intensive care 
unit, hyperpyrexia and repeated or high-grade fevers. While the safety of the subject always comes first, it 
is still important to seriously consider if unblinding the study therapy is necessary to ensure a subject’s 
safety.  
 
7.7           Stopping Rules 
This study involves a one-time pre-operative intervention prior to a planned surgical procedure. If a 
patient develops immediate, intolerable side effects including but limited to emesis, diarrhea, or heavy 
vaginal bleeding following buccal administration of misoprostol or placebo, therapy will be discontinued.

10.0        STATISTICAL CONSIDERATIONS  
 
10.1        Study Design/Study Endpoints 
 
This is a double blinded randomized, controlled trial of women undergoing either an abdominal and 
laparoscopic myomectomy at a single university-affiliated tertiary care center. Women ages 18-50 years 
of age with clinically documented, sonographic evidence of uterine fibroids being scheduled for abdominal 
myomectomy were eligible for inclusion. Eligible participants will be randomized to receive preoperative 
400cg buccal misoprostol or placebo on the basis of total fibroid volume, location (intramural or 
subserosal) and parity. Stratification by fibroid volume (or fibroid size) will be performed prior to 
randomization. Fibroid volume is defined as the cumulative volume of intramural and subserosal fibroids 
as measured on preoperative magnetic resonance imaging (MRI), or in the instance of patient 
contraindication to MRI, transvaginal ultrasound (TVUS). The data collection sheet (addendum) and chart 
of study variables below include definition of this variable and allow for ease of recording and tracking of 
this variable in our study database. Women with a history of gynecologic malignancy, critical anemia or 
blood dyscrasias and those with a history of prior myomectomies will be excluded.

10.2        Sample Size and Accrual 
Power calculation based on the standard deviation in published reports (5) demonstrates that enrollment 
of 25 participants per arm is necessary to detect 1 standard deviation difference with 90% power. Further, 
published results from pilot studies in this population (7) and demonstrates that enrollment of 25 
participants per arm is necessary to detect 0.5g/dL difference in hemoglobin with 90% power.  
 
Prentice Women’s Hospital of Northwestern Memorial performed over 100 abdominal myomectomies in 
2013. Across a year-long study period, we anticipate identifying a minimum of 70 patients to evaluate our 
primary hypothesis. We have increased our sample size from 50 to 70 to account for the 9 participants 
that were either consented by a non-study team member, did not get the study drug due to an error at 
pharmacy or left the hospital after surgery thus we could not obtain a POD 1 which is needed for data 
analysis. 
 
Following data collection from at least 20 participants in each arm, standard deviation calculations will be 
performed to confirm that the standard deviations in our sample population is similar. Power calculation 
will be repeated using the standard deviations in our active and placebo groups and additional 
participants will be enrolled as needed to achieve adequate power to evaluate our primary outcome of 
intraoperative blood loss. 
 
 
10.3        Data Analyses Plans 
To determine whether women who take a pre-operative dose of misoprostol experince lower blood loss 
during abdominal myomectomy compared to matched controls who take placebo, we will perform linear 
regression. We will use this model to assess for the role of numerous covariates, including gravidity, 
parity and age. Secondary outcomes of percent hemoglobin drop, duration of procedure and length of 
inpatient hospitalization will be assessed using the T test and further evaluated with multivariate-adjusted 
linear regression where appropriate. The need for post-operative blood transfusion between groups will 
be assessed with the Chi-square (Fischer’s exact) test. The role of numerous potential covariates will be 
assessed with Chi-square (Fischer’s exact) test for dichotomous variables and T test for continuous 
variables with p <0.05.  
11.0        STUDY MANAGEMENT 
11.1          Conflict of Interest 
  
None to disclosure.  All investigators will follow the University conflict of interest policy. 
 
11.2  Institutional Review Board (IRB) Approval and Consent 
It is expected that the IRB will have the proper representation and function in accordance with federally 
mandated regulations. The IRB should approve the consent form and protocol. 
  
In obtaining and documenting informed consent, the investigator should comply with the applicable 
regulatory requirement(s), and should adhere to Good Clinical Practice (GCP) and to ethical principles 
that have their origin in the Declaration of Helsinki. 
         
 
Before recruitment and enrollment onto this study, the patient will be given a full explanation of the study 
and will be given the opportunity to review the consent form. Each consent form must include all the 
relevant elements currently required by the FDA Regulations and local or state regulations. Once this 
essential information has been provided to the patient and the investigator is assured that the patient 


STU00091259 
________________________________________________________________________ 
20 
understands the implications of participating in the study, the patient will be asked to give consent to 
participate in the study by signing an IRB‑approved consent form. 
  
Prior to a patient’s participation in the trial, the written informed consent form will be signed and 
personally dated by the patient and by the person who conducted the informed consent discussion. 
 
Patients who have their pre-op appointment via telehealth calls will also be able to consent as participants 
using an eConsent form through the secure Northwestern University REDCap. They will be contacted 
during or after their pre-op appointment by the research coordinator to discuss the study. The research 
coordinator will consent the patient over the phone and leave time to answer any questions they have 
about participating in the study before sending the econsent form through REDCap.   
11.2          Registration Procedures 
N/A. 
11.3          Data Management and Monitoring/Auditing 
N/A. 
11.4          Adherence to the Protocol 
Except for an emergency situation in which proper care for the protection, safety, and well-being of the 
study patient requires alternative treatment, the study shall be conducted exactly as described in the 
approved protocol. 
11.4.1   Emergency Modifications 
Investigators may implement a deviation from, or a change of, the protocol to eliminate an immediate 
hazard(s) to trial subjects without prior IRB approval. 
  
For any such emergency modification implemented, a IRB modification form must be completed within 
five (5) business days of making the change. 
11.4.2   Other Protocol Deviations/Violations 
All other planned deviations from the protocol must have prior approval by the Principal Investigator and 
the IRB. According to the IRB, a protocol deviation is any unplanned variance from an IRB approved 
protocol that: 
·      Is generally noted or recognized after it occurs 
·      Has no substantive effect on the risks to research participants 
·      Has no substantive effect on the scientific integrity of the research plan or the value of the data 
collected 
·      Did not result from willful or knowing misconduct on the part of the investigator(s). 
  
An unplanned protocol variance is considered a violation if the variance: 
·      Has harmed or increased the risk of harm to one or more research participants. 
·       Has damaged the scientific integrity of the data collected for the study. 
·      Results from willful or knowing misconduct on the part of the investigator(s). 
·      Demonstrates serious or continuing noncompliance with federal regulations, State laws, or University 
policies. 
  
If a deviation or violation occurs without prior approval from the Principal Investigator, please follow the 
guidelines below: 


STU00091259 
________________________________________________________________________ 
21 
11.5          Amendments to the Protocol 
Should amendments to the protocol be required, the amendments will be originated and documented by 
the Principal Investigator. It should also be noted that when an amendment to the protocol substantially 
alters the study design or the potential risk to the patient, a revised consent form might be required. 
  
The written amendment, and if required the amended consent form, must be sent to the IRB for approval 
prior to implementation. 
11.6        Record Retention 
Study documentation includes all Case Report Forms, data correction forms or queries, source 
documents, Sponsor-Investigator correspondence, monitoring logs/letters, and regulatory documents 
(e.g., protocol and amendments, IRB correspondence and approval, signed patient consent forms). 
  
Source documents include all recordings of observations or notations of clinical activities and all reports 
and records necessary for the evaluation and reconstruction of the clinical research study. 
  
Government agency regulations and directives require that the study investigator must retain all study 
documentation pertaining to the conduct of a clinical trial. In the case of a study with a drug seeking 
regulatory approval and marketing, these documents shall be retained for at least two years after the last 
approval of marketing application in an International Conference on Harmonization (ICH) region. In all 
other cases, study documents should be kept on file until three years after the completion and final study 
report of this investigational study. 
11.7        Obligations of Investigators 
The Principal Investigator is responsible for the conduct of the clinical trial at the site in accordance with 
Title 21 of the Code of Federal Regulations and/or the Declaration of Helsinki. The Principal Investigator 
is responsible for personally overseeing the treatment of all study patients. The Principal Investigator 
must assure that all study site personnel, including sub-investigators and other study staff members, 
adhere to the study protocol and all FDA/GCP/NCI regulations and guidelines regarding clinical trials both 
during and after study completion. 
  
The Principal Investigator at each institution or site will be responsible for assuring that all the required 
data will be collected and entered onto the Case Report Forms. Periodically, monitoring visits will be 
conducted and the Principal Investigator will provide access to his/her original records to permit 
verification of proper entry of data. At the completion of the study, all case report forms will be reviewed 
by the Principal Investigator and will require his/her final signature to verify the accuracy of the data.

Title of Research Study:   STU00091259 
Buccal Misoprostol Prior to Myomectomy for Reduction in Intraoperative Blood Loss: A Placebo 
Controlled Randomized Trial (NCT02209545) 
 
Investigator: Magdy Milad, MD 
 
Supported By: This research is supported by the Gerbie Professorship 
 
Financial Interest Disclosure: The following disclosure is made to give you an opportunity to 
decide if this relationship will affect your willingness to participate in this research study: 
 
If your doctor is also the person responsible for this research study, please note that s/he is 
interested in both your clinical care and the conduct of this research study. You have the right to 
discuss this study with another person who is not part of the research team before deciding 
whether to participate in the research. 
 
Why am I being asked to take part in this research study? 
We are asking you to take part in this research study because you are undergoing surgery to 
remove fibroids.  
What should I know about a research study? 
• 
Someone will explain this research study to you. 
• 
Whether or not you take part is up to you. 
• 
You can choose not to take part. 
• 
You can agree to take part and later change your mind. 
• 
Your decision will not be held against you. 
• 
You can ask all the questions you want before you decide. 
 
Why is this research being done? 
The purpose of this study is to evaluate the use of a medication, misoprostol, for reducing blood 
loss during fibroid removal (myomectomy). You are being asked to participate because you are 
undergoing a surgery to remove fibroid/s from your uterus. Research suggests that a commonly 
used medication, misoprostol, may reduce blood loss during fibroid surgery. We are performing 
this research study to evaluate whether blood loss is reduced when patients receive misoprostol 
before surgery. The use of misoprostol in this context is considered experimental. 
 
How long will the research last and what will I need to do? 
We expect that you will be in this research study at the time of your surgery both pre and post 
operatively. You will need to attend all normal preoperative and postoperative visits that you 
would normally attend for this type of fibroid surgery.  
 
Key Information:  
The first few pages of this document include a summary of this study to help you 
decide whether or not to participate. Detailed information is provided after the 
summary.

Is there any way being in this study could be bad for me? 
The risks from the study procedures include the risk of discomfort from being asked to place a 
medication between your cheek and gums for 30 minutes then swallow.  
 
 
Will being in this study help me any way? 
There may be no benefit to you from this study. The possible benefits to you from this study 
include less blood loss during your fibroid surgery Taking part in this study may help scientists 
to better how to reduce blood loss during fibroid surgery. Your participation may one day benefit 
other women, allow them to recover from surgery more quickly or even save their life. 
. 
 
What happens if I do not want to be in this research? 
Participation in research is completely voluntary. You decide whether or not to participate. If you 
choose to not participate, there will be no penalty to you or loss of benefit to which you are 
entitled.   
 
You do not have to take part in this research study. Instead of being this study, you can undergo 
fibroid surgery without premedication. Speak with your doctor about your concerns or desires 
 
Who can I talk to? 
You can call us with your questions or concerns. If you have any illness or injury during your 
time on this study, you should call us promptly. Dr. Magdy Milad, M.D. is the person in charge of 
this research study. You can contact him or study personnel at 312-472-4673 during business 
hours and via a pager system after hours by calling 312-695-7269 regarding this study. 
 
This research has been reviewed and approved by an Institutional Review Board (IRB). You 
may talk to them at (312) 503-9338 or irb@northwestern.edu if: 
• 
Your questions, concerns, or complaints are not being answered by the research team. 
• 
You cannot reach the research team. 
• 
You want to talk to someone besides the research team. 
• 
You have questions about your rights as a research participant. 
• 
You want to get information or provide input about this research. 
 
How many people will be studied? 
We expect about 70 people here will be in this research study. 
 
What happens if I say “Yes, I want to be in this research”? 
If you consent to participate, you will be required to have an office visit within 90 days of your 
surgery where a review of your medical history and medications, a physical exam and 
laboratory blood tests including a measure of your blood count (hemoglobin) will be taken. This 
visit will be with your surgeon and not outside of what he/she would require prior to surgery 
regardless of your participation in this study. You will then be randomized to a treatment group 
(misoprostol or placebo (vitamin B6)) and will be provided a buccal (between gum and cheek) 
Detailed Information: 
The rest of this document includes detailed information about this study (in addition to the 
information listed above).

medication to take 1 hour before your surgery. You will have a pregnancy test as part of your 
preoperative evaluation.  
After surgery, researchers will take note of information like the amount of blood loss and your 
lab test results after surgery (at least 4 hours postoperatively), but no further participation is 
required on your part. You will receive the standard-of-care fibroid surgery regardless of your 
treatment arm or participation in this study.  
 
Randomization  
Randomization means you will be randomly assigned to a treatment based on chance, like a flip 
of a coin. Neither you nor the researcher chooses your assigned group. You will have an equal 
chance of being in either group (placebo (vitamin B6) or misoprostol).  
 
Placebo  
This study compares an active drug to a placebo. A placebo is an inactive substance made to 
look/taste like an active medicine. In this study, the placebo drug is a one-time dose of vitamin 
B6. B6 is a vitamin that is commonly taken as a supplement.You will either get the study drug, 
misoprostol or a placebo (vitamin B6). Researchers use a placebo to see if the study drug works 
better or is safer than not taking anything.  
 
Misoprostol  
Misoprostol is a commonly used medication that is prescribed for the prevention of gastric 
ulcers and controlling post-partum hemorrhage (life-threatening uterine bleeding after a vaginal 
or cesarean delivery). A low-dose of misoprostol will be used in this study. 
 
The treatment you get will be chosen by chance, like flipping a coin. Neither you nor the study 
doctor will choose what treatment you get. You will have an equal chance of being given either 
treatment. 
 
Neither you nor the study doctor will know which treatment you are getting.  
 
What are my responsibilities if I take part in this research? 
If you take part in this research, you will be responsible to attend all necessary preoperative and 
postoperative appointment with your surgeon. These appointements are the same as they 
would be for any patient undergoing a similar surgery. 
 
What happens if I say “Yes”, but I change my mind later? 
You can leave the research at any time; it will not be held against you. 
 
If you decide to leave the research, contact the investigator so that the investigator can 
withdraw you from the study.  
  
Choosing not to be in this study or to stop being in this study will not result in any penalty to you 
or loss of benefit to which you are entitled.  Specifically, your choice not to be in this study will 
not negatively affect your right to any present or future medical treatment. 
 
Detailed Risks:  
Risks from Placebo  
Vitamin B6 is given for nutritional deficiencies and is considered a safe drug. Side effects can 
include headache, nausea and, in large doses, neuropathy (weakness, numbness and pain, 
usually in your hands and feet).

Risks of Misoprostol  
The risks associated with misoprostol include: abdominal pain (7%), nausea (3%), flatulence 
(gas) (3%), headache (2%), indigestion (2%), (7%), vomiting (1%), constipation (1%). Research 
studies also identify possible side effects of diarrhea, fever and shivering. There may also be 
other side effects that we cannot predict, of either the placebo drug or misoprostol. Should you 
experience significant discomfort whether physical, psychological or otherwise, you may opt out 
of the study at any time. 
 
This study involves the use of your identifiable, personal information and there is a chance that 
a loss of confidentiality could occur. The researchers have procedures in place to lessen the 
possibility of this happening.  See the section below titled: “What happens to the information 
collected for the research?”.
