Conditions: Pain, Postoperative
Keywords: Dental pain
Sponsor: Bayer
Start date: 2019-11-12; Completion date: 2020-03-03
Enrollment: 193 participants; Allocation: RANDOMIZED; Intervention model: PARALLEL

Brief summary:
The researchers in this study wanted to find out the optimal dose of Caffeine in the combination tablet of Naproxen Sodium and Caffeine that works in patients experiencing moderate to severe pain after having wisdom teeth removed. In the US, Naproxen has been marketed since 1976, and Naproxen Sodium has been approved for over-the-counter (OTC) use since 1994 for the temporary relief of minor aches and pains. Caffeine, which is generally consumed as coffee, tea or cocoa, has been shown to enhance the effectiveness of various pain relievers, and therefore is accepted as an additive to painkillers like aspirin and acetaminophen. Patients participating in this study underwent a surgery to remove 3 or 4 wisdom teeth. If the pain severity after the surgery met the study requirement, patients would receive oral tablet(s) of Naproxen Sodium and Caffeine, or Naproxen Sodium, or Caffeine, or placebo (drug with no active ingredient). Patients could also receive additional pain medication when needed. Researchers would also learn if the patients have any medical problems during the study.

Detailed description:

Arms: arm 1: Participants received a single dose of two tablets of naproxen sodium/caffeine (low dose/medium low dose) after extraction of third molars arm 2: Participants received a single dose of two tablets of naproxen sodium/caffeine (low dose/low dose) after extraction of third molars arm 3: Participants received a single dose of one tablet of naproxen sodium/caffeine (low dose/ medium low dose) plus one tablet of placebo after extraction of third molars arm 4: Participants received a single dose of one tablet of naproxen sodium/caffeine (low dose/ low dose) plus one tablet of placebo after extraction of third molars arm 5: Participants received a single dose of one tablet of naproxen sodium (low dose) plus one tablet of placebo after extraction of third molars arm 6: Participants received a single dose of two tablets of caffeine (medium low dose) after extraction of third molars arm 7: Participants received a single dose of two tablets of matching placebo after extraction of third molars

Study Design 
4.1 
Overall Design 
Design Overview 
This is a single center, randomized, double-blind, parallel, placebo-controlled study in 
participants experiencing moderate to severe postoperative dental pain. The study will consist 
of a Prescreening telephone call, a Screening Visit, a one day Treatment Period and a Post-
Operative phone call or visit.  Eligible participants who have undergone surgical extraction of 
three or four third molars, 2 of which were mandibular partial or full bony impacted third 
molars will be kept in-house and evaluated for efficacy and safety at the study site through 
completion of all trial procedures. 
Qualified participants will then be randomized into one of seven treatments. Approximately 
300 participants will be screened prior to surgery.  Approximately 190 will have surgery and 
approximately 180 will be randomized to a specific treatment. 
Screening Phase 
Eligible participants will be screened and selected up to 28 days prior to oral surgery and 
dosing with investigational product. 
Treatment Phase 
Following selection, qualified participants will enter the Treatment Phase and be scheduled 
for their surgical teeth extractions.  After completion of the surgical teeth extractions, 
participants will remain at the study site for observation. Participants with appropriate pain 
requirement will be randomized into one of seven (7) treatment groups.  Participants will rate 
their pain severity and pain relief over the next 12 hours.  Onset of analgesia will be measured 
using a two stopwatch approach. The first stopwatch will be used to capture the time when 
any pain relief is first perceived and in certain cases, the second stopwatch will be used to 
capture the time when pain relief becomes meaningful to the participant.  After completion of 
all trial procedures, participants will be discharged from the study site. 
All participants are required to remain at the study center and complete all assessments 
regardless of rescue. 
Follow-Up Phase 
Participants will be evaluated at a post-operative visit/call approximately 2-5 days after 
discharge for follow up for any adverse events or medications not known at the time of 
treatment. 
The duration of each participant’s participation will be approximately 37 days. For an 
overview on the study design and study procedures (see Figure 1).

4.4 
End of Study (EOS) Definition 
A participant is considered to have completed the study if he/she has completed all phases of 
the study including the last scheduled procedure shown in the Schedule of Activities.  Trial 
site will have the option of either contacting participants within 2 to 5 days after surgery (by 
phone) or scheduling participants for an office appointment, depending on their standard of 
care policies, to assess the occurrence or persistence of AEs, any medications taken, and for 
adequate treatment and follow up.   
Primary completion 
The primary completion is defined as the date of the last visit of the last participant for the 
primary outcome. 
5. 
Study Population 
Prospective approval of protocol deviations to recruitment and enrollment criteria, also known 
as protocol waivers or exemptions, is not permitted. 
The participant population will consist of healthy individuals who are status post extraction of 
three or four third molars, two of which were mandibular partial or full bony impactions. 
5.1 
Inclusion Criteria 
Participants are eligible to be included in the study only if all of the following criteria apply: 
1. Healthy, ambulatory, male or female volunteers 16 years of age or older; 
2. Body mass index 18.5 to 35.0 kg/m2 inclusive as measured by the NIH BMI 
Calculator; 
3. Participants will undergo surgical extraction of three or four third molars, two of 
which must be mandibular molars. Maxillary third molars may be removed regardless 
of impaction level.  The mandibular extractions must have a trauma rating of mild or 
moderate and meet one of the following scenarios: 
• two full bony impactions 
• two partial bony impactions 
• one full bony impaction in combination with one partial bony impaction 
Supernumerary teeth present may also be removed at the discretion of the oral 
surgeon; 
5. Have not taken any form of medication, nutritional supplements with analgesic 
properties (e.g. GABA, turmeric) or herbal supplements (i.e., St. John’s Wort) within 
5 days of admission (except for oral contraceptives, prophylactic antibiotics, 
multivitamin supplements, or other routine medications to treat benign conditions 
(such as antibiotics to treat acne), and agree not to take any medication (other than that 
provided to them) throughout the study;

6. Female participants of childbearing potential must: a) be using a medically acceptable 
form of birth control [e.g., hormonal contraceptives (oral, patch, injectable or vaginal 
ring), implantable device (implantable rod or intrauterine device), or a double barrier] 
for at least 1 month prior to screening (3 months on oral contraceptives); b) abstain 
from sexual intercourse for at least 1 month prior to screening; or c) participate 
exclusively in a same sex relationship for at least 1 month prior to screening.  In 
addition, female participants of childbearing potential must have a negative pregnancy

5.3.1 
Meals and Dietary Restrictions 
Participants will be instructed not to consume food that contains caffeine (e.g., chocolate, ice 
cream) two days prior to surgery. 
 
5.3.2 
Alcohol 
Participants will be instructed not to consume alcohol beverages 24 hours prior to surgery. 
 
5.4 
Screen Failures 
Screen failures are defined as participants who consent to participate in the clinical study but 
are not subsequently randomly assigned to study intervention. A minimal set of screen failure 
information is required to ensure transparent reporting of screen failure to respond to queries 
from regulatory authorities. Minimal information includes demography, screen failure details, 
eligibility criteria, and any serious adverse event (SAE). 
Individuals who do not meet the criteria for participation in this study (screen failure) due to 
scheduling surgery may be rescreened.  A previous dental x-ray if taken during the original 
screening visit can be used when rescreened.  Rescreened participants should be assigned a 
new participant number. 
5.5 
Run-in Failures 
A participant who, for any reason terminates the study after surgery and prior to the start of 
study drug administration (e.g., not meeting pain threshold) is regarded as a “Run-in failure”. 
 
5.6 
Dropouts 
A participant who discontinues study participation prematurely for any reason is defined as a 
“dropout” if the participant has been randomized and administered at least one dose of study 
drug. 
 
5.7 
General Procedures 
In all cases, the reason for withdrawal must be recorded on the screening log and in the 
participant's medical records.  
The participant may object to the generation and processing of post-withdrawal data as 
specified in Section 10.1.8. 
Details for the premature termination of the study as a whole (or components thereof) are 
provided in Section 10.1.14 (Premature termination of the Study).

6.2 
Preparation/Handling/Storage/Accountability 
All study drugs will be labeled according to the requirements of local law and legislation.  
Label text will be approved according to the sponsor’s agreed procedures, and a copy of the 
labels will be made available to the study site upon request. 
For all study drugs, a system of numbering in accordance with all requirements of Good 
Manufacturing Practice (GMP) will be used, ensuring that each dose of study drug can be 
traced back to the respective bulk batch of the ingredients.  Lists linking all numbering levels 
will be maintained by the sponsor’s clinical supplies Quality Assurance (QA) group.  
A complete record of batch numbers and expiry dates of all investigational products as well as 
the labels will be maintained in the clinical supply file. 
The source of test and reference products will be documented in the clinical supply file. 
The investigator or designee must confirm appropriate temperature conditions have been 
maintained during transit for all study intervention received and any discrepancies are 
reported and resolved before use of the study intervention.  Only participants enrolled in the 
study may receive study intervention and only authorized site staff may supply or administer 
study intervention. All study intervention must be stored in a secure, environmentally 
controlled, and monitored (manual or automated) area in accordance with the labeled storage 
conditions with access limited to the investigator and authorized site staff.  The investigator, 
institution, or the head of the medical institution (where applicable) is responsible for study 
intervention accountability, reconciliation, and record maintenance (i.e., receipt, 
reconciliation, and final disposition records). 
The Sponsor will provide sufficient quantity of the IMP to the study site.  The study center 
will dispense IMP according to the randomization schedule and the participant’s categorical 
pain intensity (moderate or severe) post-surgery.  IMP will be supplied to the study center in 
multi-dose bottles and dispensed by an unblinded member of the study team. 
All study drugs will be stored at the investigational site in accordance with GCP requirements 
and the instructions given by the clinical supplies department of the sponsor (or its 
affiliate/CRO), and will be inaccessible to unauthorized personnel. Special storage conditions 
and a complete record of batch numbers and expiry dates can be found in the Sponsor’s study 
file; the site-relevant elements of this information will be available in the investigator site file. 
On the day of receipt, the responsible site personnel will confirm receipt of study 
investigational products in writing. The personnel will use the study investigational products 
only within the framework of this clinical study and in accordance with this protocol. Receipt, 
distribution, return and destruction (if any) of the study drug must be properly documented 
according to the sponsor’s agreed and specified procedures. 
6.3 
Measures to Minimize Bias: Randomization and Blinding 
On Day 1, participants will be assigned a unique number (randomization number) in 
ascending numerical order at the study site. The randomization number encodes the 
participant’s assignment to one of the seven (7) arms of the study, according to the 
randomization schedule generated prior to the study by the Sponsor. Each participant will be 
dispensed blinded study intervention, labeled with his/her unique randomization number, 
throughout the study. 
Participants enrolled in the trial, investigators and their staff involved in protocol procedures 
or who are involved in data collection, data entry and data analysis will be blinded to the

identity of the treatments until the database is locked. The study monitor will conduct product 
accountability after database lock. To preserve blinding, participants will be blindfolded 
during administration of study medication.  Study drug will be dispensed by an unblinded 
study team member based on the randomization schedule.  That team member may have no 
other role in the study conduct and may not reveal the study drug’s identity to any members 
of the blinded study team. 
Sponsor will supply study medication in bulk containers.  Selection of the proper dose for an 
individual participant will be performed by an unblinded study team member using the 
provided randomization schedule.  The unblinded study team member will withdraw the 
appropriate study medication from the bulk container and transfer it to a dispensing cup.  All 
study interventions must be administered as 2 tablets per participant.  Some study 
interventions require the addition of a placebo tablet.  The unblinded study team member will 
then bring the study medication to the treatment room where it will be dispensed to the 
participant by the study team member.  The unblinded study team member should have no 
other responsibilities in the study. 
 
6.3.1 
Unblinding 
In the case of a medical emergency, such as serious adverse events (SAE), breaking the blind 
may become necessary during the trial 
In compliance with applicable regulations, in the event of a serious unexpected adverse event 
(SUSAR) related to the blinded treatment, the participant’s treatment code will usually be 
unblinded before reporting to the health authorities, ethic committees and investigators (see 
Section 8.3.5). 
 
6.3.2 
Emergency unblinding by the investigator 
The investigator must report the blind break in conjunction with a SAE within 24 hours of 
becoming aware of the effect as defined in Section 10.3.1.  Participants who have been 
unblinded will not be included in the ITT or PP efficacy analysis. 
6.4 
Study Intervention Compliance 
The administration of the study medication will be supervised by an unblinded member of the 
Investigator’s team. This person will perform the oral cavity inspection after study drug 
administration and document that the participant receives the treatment as planned. 
6.5 
Prior and Concomitant Therapy 
The following treatments are prohibited from screening and during the study:  
 
• Use of any form of medication or herbal supplements, including GABA and turmeric, 
or curcumin, within 5 days of surgery that would confound the evaluation of the study 
product, until discharge from the study site; 
• Use of acetaminophen, naproxen, hydrocodone/acetaminophen, ibuprofen, aspirin, or 
other NSAIDs or any other pain reliever (OTC or prescription) within 5 days before 
surgery;

Version 1.0 / 22 Aug 2019                     Page 27 of 61 
 
• Use of alcoholic beverages after midnight prior to surgery and throughout the 
evaluation period; 
All medications (prescription and nonprescription products, vitamin and herbal products) 
taken by the participant from 30 days prior to Screening to End of Trial (EOT) will be 
documented.  The reported medications will be reviewed and evaluated by the Principal 
Investigator or designee to determine if they affect the participant’s eligibility to participate in 
the study. 
 
6.5.1 
Rescue Medicine 
If adequate pain relief was not achieved, then participants are permitted to take rescue 
medication, although they will be encouraged to wait 2 hours to allow the investigational 
product time to take effect.  The study site will supply the rescue medication that will be 
obtained locally.  Rescue medication will be Hydrocodone 5 mg/Acetaminophen 325 mg 
tablets or other appropriate analgesics may be used at the discretion of the Investigator.  
Rescue medication is also available on return of pain and the time of rescue medication will 
be recorded.  Pain assessments will be performed immediately before the first dose of rescue 
medication. 
• Rating of Pain Intensity (NRS); 
• Rating of Pain Relief (Categorical); 
• Global Assessment of investigational product as a pain reliever. 
All active stopwatch elapsed time(s) will be stopped at the time of rescue administration and 
recorded on the case report form. 
Participants will be queried in a nonspecific fashion for any adverse events.  All observed and 
reported AEs will be collected and recorded on the case report form.  The information 
recorded will be based on signs and symptoms reported by the participant or observed by the 
research coordinator during clinical evaluation. 
6.6 
Dose Modification 
The dosing schedule cannot be modified. 
6.7 
Intervention after the End of the Study 
This study is a single dose administration after surgery and there is no additional treatment 
allocated.  Participants who randomize into the study will be discharged from the study center 
after the final (12 hour post dosing) assessments, regardless of whether rescue medication had 
been taken or not. 
7. 
Discontinuation of Study Intervention and Participant  
 
7.1 
Discontinuation of Study Intervention  
See the SoA for data to be collected at the time of intervention discontinuation and follow-up 
and for any further evaluations that need to be completed.

7.2 
Participant Discontinuation/Withdrawal from the Study 
Withdrawal criteria 
Participants must be withdrawn from the study if any of the following occurs: 
• A participant may withdraw from the study at any time at his/her own request, or may 
be withdrawn at any time at the discretion of the investigator for safety, behavioral, 
compliance, or administrative reasons. This is expected to be uncommon. 
• At the time of discontinuing from the study, if possible, an early discontinuation visit 
should be conducted, as shown in the SoA. See SoA for data to be collected at the 
time of study discontinuation and follow-up and for any further evaluations that need 
to be completed. 
• The participant will be permanently discontinued both from the study intervention and 
from the study at that time. 
• If the participant withdraws consent for disclosure of future information, the sponsor 
may retain and continue to use any data collected before such a withdrawal of consent. 
• Participant’s pain intensity post-surgery at pre-dose does not exceed ‘mild’ and the NRS 
is <5 (see Section 10.5); 
• If, in the Investigator's opinion, continuation of the study would be harmful to the 
participant's well-being; 
 
Participants may be withdrawn from the study if any of the following occurs: 
• Participant experiences one or more serious adverse events; 
• At the specific request of the Sponsor and in consultation with the Investigator (e.g., 
obvious non-compliance, safety concerns); 
• Protocol violation: if the participant develops conditions, which would have prevented 
his/her entry into the study according to the inclusion/exclusion criteria, he/she must be 
withdrawn immediately if safety is concerned; in other cases, the investigator will 
decide whether there is a conflict with the study objectives. 
7.3 
Lost to Follow Up 
A participant will be considered lost to follow-up if he or she repeatedly fails to return for 
scheduled visits and is unable to be contacted by the study site.  
The following actions must be taken if a participant fails to return to the clinic for a required 
study visit: 
• The site must attempt to contact the participant and reschedule the missed visit as soon 
as possible and counsel the participant on the importance of maintaining the assigned 
visit schedule and ascertain whether or not the participant wishes to and/or should 
continue in the study. 
• Before a participant is deemed lost to follow up, the investigator or designee must 
make every effort to regain contact with the participant (where possible, 3 telephone 
calls and, if necessary, a certified letter to the participant’s last known mailing address 


CONFIDENTIAL 
Clinical Study Protocol 
BAY 2880376 / 21069 
Version 1.0 / 22 Aug 2019                     Page 29 of 61 
 
or local equivalent methods). These contact attempts should be documented in the 
participant’s medical record. 
• Should the participant continue to be unreachable, he/she will be considered lost to 
follow up. 
8. 
Study Assessments and Procedures 
Study procedures and their timing are summarized in the SoA. Protocol waivers or 
exemptions are not allowed.  Immediate safety concerns should be discussed with the sponsor 
immediately upon occurrence or awareness to determine if the participant should continue or 
discontinue study intervention. Adherence to the study design requirements, including those 
specified in the SoA, is essential and required for study conduct. 
 
All screening evaluations must be completed and reviewed to confirm that potential 
participants meet all eligibility criteria. The investigator will maintain a screening log to 
record details of all participants screened and to confirm eligibility or record reasons for 
screening failure, as applicable.  
 
Procedures conducted as part of the participant’s routine clinical management (e.g., blood 
count) and obtained before signing of the ICF may be utilized for screening or baseline 
purposes provided the procedures met the protocol-specified criteria and were performed 
within the time frame defined in the SoA. 
 
8.1 
Efficacy Assessments 
If not stated otherwise, the measures / actions listed in the following Sections 8.1.1 to 8.1.6 
will be performed by a designated study team member as designated by the Principal 
Investigator. 
8.1.1 
Screening Period 
Note: No screening procedures may be performed unless participants have been 
provided an IRB-approved written informed consent which participants have read, 
understood, and signed.  
 
The Screening Period will be up to 28 days long.  The following will be determined during 
the Screening Visit: 
• Signed Informed Consent Form (ICF); 
• Review inclusion and exclusion criteria; 
• Participant demographics; 
• Medical/surgical history including history of drug, alcohol, tobacco and caffeine 
use; 
• Medication history of all prescription, OTC products including vitamins or 
dietary/herbal supplements, taken during the past 30 days; 
• Vital signs consisting of sitting blood pressure (in triplicate with one min in 
between), respiratory rate and pulse after sitting for at least 5 minutes; 


CONFIDENTIAL 
Clinical Study Protocol 
BAY 2880376 / 21069 
Version 1.0 / 22 Aug 2019                     Page 30 of 61 
 
• Physical and oral examination; 
• Dental x-ray examination and interpretation including impaction score; 
Note: The medical interpretation may occur after the screening visit provided a 
diagnosis of impaction is determined prior to surgery. 
• Urine tests for illicit drugs; 
• Breath or saliva alcohol test; 
• Urine pregnancy test (if applicable). 
Upon satisfying the inclusion/exclusion criteria, eligible participants will be instructed to return 
to the trial site within 28 days for oral surgery.  Participants will be instructed to refrain from 
the use of all medications (prescription, nonprescription, herbal supplements) unless in the 
opinion of the Investigator or Sponsor, the medication will not interfere with study procedures, 
data integrity, or compromise the safety of the participants. 
Participants will be instructed not to consume alcohol or use any nicotine containing products 
24 hours prior to surgery.  Surgery will be scheduled between 0530 h and 1030 h. 
The Principal Investigator or his/her designee must review participant’s study records before 
qualifying the participant for the trial. 
 
8.1.2 
Pre-surgery 
Participants are instructed to be nil per os (NPO) from midnight prior to surgery.  If a participant 
had something to eat or drink after midnight, the surgeon must determine if surgery may 
proceed.  Participants will arrive at the unit at their assigned time and will have the following 
activities completed prior to dental surgery: 
• Review changes in the participant’s medical/medication history and 
inclusion/exclusion criteria since previous visit; 
• Urine tests for illicit drugs; 
• Breath or saliva alcohol test; 
• Vital signs consisting of sitting blood pressure (in triplicate with one min in 
between), respiratory rate and pulse after sitting for at least 5 minutes; 
•  Urine pregnancy test (if applicable); 
• Review pain assessment process and procedures. 
 
8.1.3 
Impaction Score 
An Impaction Score will be used to assess each tooth based on the radiographic appearance and the 
intraoral examination.  Each tooth will be rated from 1 to 4 using the following criteria: 
(1) erupted in tissue (2) soft tissue impaction (3) partial bony impaction, and (4) full bony 
impaction.  Only participants whose mandibular impactions are scored (3) or (4) will be eligible to 
participate in the study.

to arrange follow-up evaluations at appropriate intervals to document the course of the 
abnormalities. 
 
Participants will be allowed the use of ice following the use of rescue medication.  Ice will not 
be permitted for participants prior to randomization until after they have been administered 
rescue medication (if applicable).  If participant has been administered rescue, ice will be given 
as requested by the participant for 20 minute increments.  Upon completion of all trial 
procedures, participants will be discharged from the trial site.  Participants will need to make 
prior arrangements for travel and should not drive themselves home. 
8.2 
Safety Assessments  
Safety measures will be analyzed for all participants in the safety population.   
Adverse events will be collected throughout the treatment and safety follow-up periods and 
will be coded using the Medical Dictionary for Regulatory Activities (MedDRA) dictionary.  
Only treatment-emergent AEs will be included, i.e., AEs that begin or worsen after the first 
dose of the investigational products in the treatment period.  The number and percent of 
participants who experience any event, by System Organ Class (SOC), and by Preferred Term 
will be displayed by treatment group.  Tables will also be produced by severity and 
relationship to investigational product. Seriousness, severity, relationship to investigational 
product, duration, and outcome will also be listed. 
Planned time points for all safety assessments are provided in the SoA. 
 
8.2.1 
Physical Examinations 
The physical examination (by means of inspection, palpation, auscultation) will be performed 
by qualified medical staff (e.g., a physician, oral surgeon, nurse practitioner or physician 
assistant) at the study site covering at least the organs of the head/neck, cardiovascular, and 
respiratory systems. 
Abnormal physical examination findings are recorded either as medical history or as adverse 
events (see Section 10.3.1). 
 
8.2.2 
Vital Signs 
Systolic and diastolic blood pressure and heart rate will be measured (in triplicates allowing 
one minute in between measurements) by a member of the investigator’s team under the 
following conditions: 
• Systolic blood pressure (after resting for at least 5 min in sitting position); 
• Diastolic blood pressure (after resting for at least 5 min in sitting position); 
• Heart rate (after resting for at least 5 min in sitting position); 
• Measuring site: cuff to be placed on the right / left upper arm (if possible, the same arm 
will be used for all measurements in one participant); cuff location will be documented; 
• Method: oscillometric by automatic measurement device.

Version 1.0 / 22 Aug 2019                     Page 34 of 61 
 
Blood pressure is to be taken in triplicates, one minute apart to enhance accuracy as suggested 
in the FDA guidance (Assessment of Pressor Effect of Drugs, May, 2018). 
 
8.2.3 
Clinical Safety Laboratory Assessments 
Urine samples will be collected by a member of the investigator’s team, for time points and 
parameters see Section 1.3. 
 
8.2.4 
Other Procedures and Variables 
Eligible participants will undergo an oral examination and a dental x-ray (radiograph) exam to 
confirm that impacted third molar teeth are present. 
 
8.3 
Adverse Events and Serious Adverse Events 
The definitions of an AE or SAE can be found in Section 10.3. 
AE will be reported by the participant (or, when appropriate, by a caregiver, surrogate, or the 
participant's legally authorized representative or health care professional not involved in the 
study).  
The investigator and any qualified designees are responsible for detecting, documenting, and 
recording events that meet the definition of an AE or SAE. They remain responsible for 
following up SAEs, or AEs considered related to the study intervention or study procedures, 
or those that caused the participant to discontinue the study. 
 
8.3.1 
Time Period and Frequency for Collecting AE and SAE Information  
All AEs and SAEs will be collected from the signing of the ICF until the follow up visit at the 
time points specified in the SoA (Section 1.3). 
Medical occurrences that begin before the start of study intervention but after obtaining 
informed consent will be recorded on the Medical History/Current Medical Conditions 
section of the case report form (CRF) not the AE section. 
All SAEs will be recorded and reported to the sponsor or designee immediately and under no 
circumstances should this exceed 24 hours, as indicated in Section 10.3.2. The investigator 
will submit any updated SAE data to the sponsor within 24 hours of it being available. 
Investigators are not obligated to actively seek AE or SAE after conclusion of the study 
participation. However, if the investigator learns of any SAE, including a death, at any time 
after a participant has been discharged from the study, and he/she considers the event to be 
reasonably related to the study intervention or study participation, the investigator must 
promptly notify the sponsor. 
 
8.3.2 
Expected Adverse Events 
For this study, the applicable reference document is the most current version of the DFL and 
IB for naproxen and caffeine.  If relevant new safety information is identified, the information 


CONFIDENTIAL 
Clinical Study Protocol 
BAY 2880376 / 21069 
Version 1.0 / 22 Aug 2019                     Page 35 of 61 
 
will be integrated into an update of the safety information and distributed to all participating 
sites. 
The expectedness of AEs will be determined by the sponsor according to the applicable 
reference document and according to all local regulations. 
 
8.3.3 
Method of Detecting AEs and SAEs 
The method of recording, evaluating, and assessing causality of AE and SAE and the 
procedures for completing and transmitting SAE reports are provided in Section 10.3. 
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended and 
non-leading verbal questioning of the participant is the preferred method to inquire about AE 
occurrences.  
8.3.4 
Follow-up of AEs and SAEs 
After the initial AE/SAE report, the investigator is required to proactively follow each 
participant at subsequent visits/contacts. All SAEs will be followed until resolution, 
stabilization, the event is otherwise explained, or the participant is lost to follow-up (as 
defined in Section 7.3). Further information on follow-up procedures is given in Section 10.3.  
 
8.3.5 
Regulatory Reporting Requirements for SAEs 
Prompt notification by the investigator to the sponsor of an SAE is essential so that legal 
obligations and ethical responsibilities towards the safety of participants and the safety of a 
study intervention under clinical investigation are met.  
The sponsor has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a study intervention under clinical investigation. The 
sponsor will comply with country-specific regulatory requirements relating to safety reporting 
to the regulatory authority, Institutional Review Boards (IRB)/Independent Ethics 
Committees (IEC), and investigators. 
Investigator safety reports must be prepared for suspected unexpected serious adverse 
reactions (SUSAR) according to local regulatory requirements and sponsor policy and 
forwarded to investigators as necessary. 
An investigator who receives an investigator safety report describing an SAE or other specific 
safety information (e.g., summary or listing of SAEs) from the sponsor will review and then 
file it along with the Investigator’s Brochure and will notify the IRB/IEC, if appropriate 
according to local requirements.  Send the SAE CRF pages and complementary forms to: 
 or Fax: 
 (in the USA) 
 
8.3.6 
Pregnancy 
A participant’s participation is to be terminated immediately if a pregnancy is supposed 
(i.e. in case her pregnancy test becomes positive).   
The investigator must report to the sponsor any pregnancy occurring in a female study 
participant during her participation in this study.  The outcome of the pregnancy should be 
followed up carefully, and any outcome of the mother and the child at delivery should be

Treatment of Overdose 
For this study, any dose of study intervention greater than single dose study intervention 
within a 12-hour time period will be considered an overdose. 
The sponsor does not recommend specific treatment for an overdose. 
In the event of an overdose, the investigator/treating physician should: 
• Contact the Medical Monitor immediately; 
• Closely monitor the participant for any AE/SAE; 
• Document the quantity of the excess dose as well as the duration of the overdose in the 
CRF.

contain a more comprehensive explanation than described below of the methodology used in 
the statistical analyses.  The SAP will also contain the rules and data handling conventions 
used to perform the analyses, and the procedure used for accounting for missing data. 
 
9.1 
Statistical Hypotheses 
The primary efficacy endpoint is the sum of change in pain intensity from 0 to 8 hours 
(SPID0-8). No multiplicity adjustment will be made. All statistical comparisons will be made 
at significance level of 0.05. 
 
9.2 
Sample Size Determination  
The study is not statistically powered. From operational feasibility point of view, a total of 
approximately 180 participants (30 participants per active treatment arm and 15 in the 
caffeine and placebo arms using a 2:2:2:2:2:1:1 ratio) are chosen, a total of  approximately 
190 participants will be randomized into the study if a drop-out rate of 5% is assumed.

9.3 
Populations for Analyses  
For purposes of analysis, the following populations are defined: 
Population 
Description 
Safety 
All participants who are randomized and take at least one 
dose of investigational product.  Safety measures will be 
analyzed for all participants in the safety population. 
Intent-To-Treat (ITT) 
All participants in the Safety Population who provide at 
least one pain assessment after the first dose of the 
investigational product.  ITT population will be used as 
secondary to conduct the sensitivity analysis for the 
selected parameters.   
Per Protocol (PP) Population 
PP population will include all participants in ITT who do 
not have any major protocol violations and complete the 
12 hour assessments. PP population will be used as the 
primary analysis for the efficacy parameters. 
 
Major protocol deviations will be identified prior to 
database lock and may include but are not limited to 
significant violations of inclusion/exclusion criteria, 
noncompliance of the trial treatment taken, conditions 
such as vomiting and diarrhea or use of prohibited 
medications, and not following clinical trial protocol 
procedures.  Any participant who rescues or vomits at or 
prior to 60 minutes after ingesting study medication will 
be excluded from the PP population. 
 
9.4 
Statistical Analyses 
The statistical analysis plan (SAP) will be developed and finalized before database lock and 
will describe the participant populations to be included in the analyses, and procedures for 
accounting for missing, unused, and spurious data. This section is a summary of the planned 
statistical analyses of the primary and secondary endpoints. 
 
9.4.1 
Efficacy Analyses 
For each post-dose time point, Pain Intensity Differences (PID) will be derived by subtracting 
the pain intensity at the post-dose time point from the baseline intensity score (baseline score 
– post-baseline score).  A positive difference is indicative of improvement.  Time-weighted 
Sum of Pain Intensity Differences (SPIDs) will be calculated for 2, 4, 8, and 12 hours by

BAY 2880376 / 21069 
Version 1.0 / 22 Aug 2019                     Page 39 of 61 
 
multiplying the PID score at each post-dose time point by the duration (in hours) since the 
preceding time point and then summing these values over 2, 4, 8, and 12 hours, respectively.   
Similarly, Total Pain Relief Scores (TOTPARs), will be calculated by multiplying the pain 
relief score at each post-dose time point by the duration (in hours) since the preceding time 
point and then summing these values. 
In all analyses for participants who take rescue medication, all pain intensity scores after 
intake of rescue medication will be imputed by the worse of the baseline or the score assessed 
immediately before taking rescue medication. All pain relief after intake of rescue medication 
will be imputed by “no relief” (0). 
 
Endpoint 
Statistical Analysis Methods 
Primary 
The primary efficacy analyses population will be based on the PP 
population. 
 
Sum of Pain Intensity Difference over 8 hours: SPID0-8 be analyzed 
using an analysis of covariance model (ANCOVA) with treatment as 
fixed effect and baseline pain intensity score as the covariate.  A 95% 
of confidence interval (CI) for the treatment differences and pairwise 
p-values will be calculated based on the above mentioned model. 
Secondary 
Total Pain Relief over 8 hours: TOTPAR0-8 will be analyzed 
similarly as for the primary endpoint. 
 
Time to first use of rescue medication.  If a participant did not take 
the rescue medication during the treatment period, (s)he will be 
censored at the time of last assessment. Time to first use of rescue 
medication will be estimated and plotted using Kaplan-Meier method 
and analyzed using log-rank test.

Funding 
This study will be funded by its sponsor. 
 
10.1.4 
Informed Consent Process 
All relevant information on the study will be summarized in an integrated participant 
information sheet and informed consent form provided by the sponsor or the study center.  
Sample participant information and informed consent/assent forms are provided as a 
document separate to this protocol.  Participants 16 to 17 years old who cannot legally give 
informed consent for research participation must use an IRB-approved assent form and a 
Parental/Guardian informed consent form.  Informed consent must first be obtained from the 
child’s parent or legal guardian before assent may be obtained from the child. 
Based on this participant information sheet, the investigator or his/her representative will 
explain the nature of the study to the participant or his/her legally authorized representative 
and answer all questions regarding the study.  Participants must be informed that their 
participation is voluntary. Participants will be required to sign a statement of informed 
consent that meets the requirements of 21 CFR 50, local regulations, ICH guidelines, Health 
Insurance Portability and Accountability Act (HIPAA) requirements, where applicable, and 
the IRB/IEC or study center. 
The investigator will also mention that written approval of the IRB has been obtained. 
Each participant will be informed about the following aspects of premature withdrawal: 
• Each participant has the right to withdraw from the study at any time without any 
disadvantage and without having to provide reasons for this decision;   
• The participant’s consent covers EOT examinations as specified in the visit 
description described in Section 7.2 to be conducted after withdrawal of consent; 
• The participant’s data that have been collected until the time of withdrawal will be 
retained and statistically analyzed in accordance with the statistical analysis plan; 
• Participant-specific data on the basis of material obtained before withdrawal may be

in accordance with the statistical analysis plan.  The participant has the right to object 
to the generation and processing of this post-withdrawal data.  For this, he/she needs 
to sign a corresponding declaration of objection; alternatively, the participant’s oral 
objection may be documented in the participant’s source data. 
Each participant will have ample time and opportunity to ask questions. 
Only if the participant agrees to sign the informed consent form and has done so, may he/she 
enter the study.  Additionally, the investigator will personally sign and date the form.  The 
participant will receive a copy of the signed and dated form. 
The medical record must include a statement that written informed consent was obtained 
before the participant was enrolled in the study and the date the written consent was obtained. 
The authorized person obtaining the informed consent must also sign the ICF.  In the event 
that informed consent is obtained on the date that baseline study procedures are performed, 
the study record or participant´s clinical record must clearly show that informed consent was 
obtained prior to these procedures. 
For minors or adults under legal protection, consent shall be given by the legal guardian(s). 
The consent of a minor or adult under legal protection shall also be requested where such a 
person is able to express his/her own will. His/her refusal or the withdrawal of his/her consent 
may not be disregarded. 
The informed consent form and any other written information provided to participants will be 
revised whenever important new information becomes available that may be relevant to the 
participant’s consent, or there is an amendment to the protocol that necessitates a change to 
the content of the participant information and / or the written informed consent form.  The 
investigator will inform the participant of changes in a timely manner and will ask the 
participant to confirm his/her participation in the study by signing the revised informed 
consent form.  Any revised written informed consent form and written information must 
receive the IRB`s approval / favorable opinion in advance of use. 
Participants who are rescreened are required to sign a new ICF. 
 
10.1.5 
Data Protection and Confidentiality 
Any participant records or datasets that are transferred to the sponsor will contain the 
identifier only; participant names or any information which would make the participant 
identifiable will not be transferred.  The participant must be informed that his/her personal 
study-related data will be used by the sponsor in accordance with local data protection law. 
The level of disclosure must also be explained to the participant.  The participant must be 
informed that his/her medical records may be examined by Clinical Quality Assurance 
auditors or other authorized personnel appointed by the sponsor, by appropriate IRB/IEC 
members, and by inspectors from national or international regulatory authorities. 
All records identifying the participant will be kept confidential and, to the extent permitted by 
the applicable laws and/or regulations, will not be made publicly available.

The investigator/institution agrees to allow the auditor or inspector direct access to all relevant 
documents and allocate his/her time and the time of his/her staff to the auditor/inspector to 
discuss findings and any issues.  Audits and inspections may occur at any time during or after 
completion of the study. 
 
10.1.13 
Archiving 
Essential documents shall be archived safely and securely in such a way that ensures that they 
are readily available upon authorities’ request. 
Participant files will be archived according to local regulations and in accordance with the 
maximum period of time permitted by the hospital, institution or private practice.  Where the 
archiving procedures do not meet the minimum timelines required by the sponsor, alternative 
arrangements must be made to ensure the availability of the source documents for the required 
period. 
The investigator / institution notifies the sponsor if the archival arrangements change (eg 
relocation or transfer of ownership). The investigator site file is not to be destroyed without 
the sponsor’s approval. The contract with the investigator/institution will contain all 
regulations relevant for the study center. 
 
10.1.14 
Study and Site Closure 
The sponsor designee reserves the right to close the study site or terminate the study at any 
time for any reason at the sole discretion of the sponsor. Study sites will be closed upon study 
completion. A study site is considered closed when all required documents and study supplies 
have been collected and a study-site closure visit has been performed. 
The investigator may initiate study-site closure at any time, provided there is reasonable cause 
and sufficient notice is given in advance of the intended termination. 
Reasons for the early closure of a study site by the sponsor or investigator may include but are 
not limited to: 
• Failure of the investigator to comply with the protocol, the requirements of the 
IRB/IEC or local health authorities, the sponsor's procedures, or GCP guidelines 
• Inadequate recruitment of participants by the investigator 
• Discontinuation of further study intervention development 
 
10.1.15 
Publication Policy 
The results of this study may be published or presented at scientific meetings. If this is 
foreseen, the investigator agrees to submit all manuscripts or abstracts to the sponsor before 
submission. This allows the sponsor to protect proprietary information and to provide 
comments.  
The sponsor will comply with the requirements for publication of study results. In accordance 
with standard editorial and ethical practice, the sponsor will generally support publication of 
multicenter studies only in their entirety and not as individual site data. In this case, a 
coordinating investigator will be designated by mutual agreement.

10.3 
Appendix 3: Adverse Events: Definitions and Procedures for Recording, 
Evaluating, Follow-up, and Reporting 
10.3.1 
Definition of AE  
 
AE Definition 
• An AE is any untoward medical occurrence in a patient or clinical study 
participant, associated with the use of study intervention, whether or not considered 
related to the study intervention. 
• NOTE: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) associated 
with the use of study intervention. 
 
Events Meeting the AE Definition  
• Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) 
or other safety assessments (e.g., ECG, radiological scans, vital signs 
measurements), including those that worsen from baseline, considered clinically 
significant in the medical and scientific judgment of the investigator. 
• Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition. 
• New conditions detected or diagnosed after study intervention administration even 
though it may have been present before the start of the study. 
• Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction. 
• Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
intervention or a concomitant medication. Overdose per se will not be reported as 
an AE/SAE unless it is an intentional overdose taken with possible suicidal/self-
harming intent. Such overdoses should be reported regardless of sequelae. 
•  “Lack of efficacy” or “failure of expected pharmacological action” per se will not 
be reported as an AE or SAE. Such instances will be captured in the efficacy 
assessments. However, the signs, symptoms, and/or clinical sequelae resulting 
from lack of efficacy will be reported as AE or SAE if they fulfil the definition of 
an AE or SAE.

Version 1.0 / 22 Aug 2019                     Page 48 of 61 
 
Events NOT Meeting the AE Definition  
• Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the participant’s condition. 
• The disease/disorder being studied or expected progression, signs, or symptoms of 
the disease/disorder being studied, unless more severe than expected for the 
participant’s condition. 
• Medical or surgical procedure (e.g., endoscopy, appendectomy): the condition that 
leads to the procedure is the AE. 
• Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital). 
• Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) 
present or detected at the start of the study that do not worsen. 
 
10.3.2 
Definition of SAE 
An SAE is defined as any untoward medical occurrence that, at any dose: 
a. 
Results in death 
b. 
Is life-threatening 
• The term 'life-threatening' in the definition of 'serious' refers to an event in which 
the participant was at risk of death at the time of the event. It does not refer to an 
event, which hypothetically might have caused death, if it were more severe. 
c. 
Requires inpatient hospitalization or prolongation of existing hospitalization 
• In general, hospitalization signifies that the participant has been detained (usually 
involving at least an overnight stay) at the hospital or emergency ward for 
observation and/or treatment that would not have been appropriate in the 
physician’s office or outpatient setting. Complications that occur during 
hospitalization are AEs. If a complication prolongs hospitalization or fulfills any 
other serious criteria, the event is serious. When in doubt as to whether 
“hospitalization” occurred or was necessary, the AE should be considered serious. 
• Hospitalization for elective treatment of a pre-existing condition that did not 
worsen from baseline is not considered an AE. 
d. 
Results in persistent disability/incapacity 
• The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions. 
• This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, 
influenza, and accidental trauma (e.g., sprained ankle) which may interfere with or 
prevent everyday life functions but do not constitute a substantial disruption.

e. 
Is a congenital anomaly/birth defect 
f. 
Other situations: 
• Medical or scientific judgment should be exercised in deciding whether SAE 
reporting is appropriate in other situations such as important medical events that 
may not be immediately life-threatening or result in death or hospitalization but 
may jeopardize the participant or may require medical or surgical intervention to 
prevent one of the other outcomes listed in the above definition. These events 
should usually be considered serious. 
• Examples of such events include invasive or malignant cancers, intensive treatment 
in an emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalization, or development of drug 
dependency or drug abuse.

10.3.3 
Recording and Follow-Up of AE and/or SAE  
 
AE and SAE Recording 
• When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (e.g., hospital progress notes, laboratory reports, and diagnostics 
reports) related to the event. 
• The investigator will then record all relevant AE/SAE information in the CRF. 
• It is not acceptable for the investigator to send photocopies of the participant’s 
medical records in lieu of completion of the AE/SAE CRF page. 
• There may be instances when copies of medical records for certain cases are 
requested by the sponsor. In this case, all participant identifiers, with the exception 
of the participant number, will be redacted on the copies of the medical records 
before submission. 
• The investigator will attempt to establish a diagnosis of the event based on signs, 
symptoms, and/or other clinical information. Whenever possible, the diagnosis (not 
the individual signs/symptoms) will be documented as the AE/SAE. 
Assessment of Intensity 
The investigator will make an assessment of intensity for each AE and SAE reported 
during the study and assign it to one of the following categories:  
• Mild: An event that is easily tolerated by the participant, causing minimal 
discomfort and not interfering with everyday activities. 
• Moderate: An event that causes sufficient discomfort and interferes with normal 
everyday activities. 
• Severe: An event that prevents normal everyday activities. An AE that is assessed 
as severe should not be confused with an SAE. Severe is a category utilized for 
rating the intensity of an event; and both AEs and SAEs can be assessed as severe. 
• An event is defined as ‘serious’ when it meets at least 1 of the predefined outcomes 
as described in the definition of an SAE, NOT when it is rated as severe. 
Assessment of Causality 
• The investigator is obligated to assess the relationship between study intervention 
and each occurrence of each AE/SAE. 
• A “reasonable possibility” of a relationship conveys that there are facts, evidence, 
and/or arguments to suggest a causal relationship, rather than a relationship cannot 
be ruled out. 
• Possible answers are “yes” or “no” 
• An assessment of “no” would include: 
o The existence of a highly likely alternative explanation, e.g., mechanical 
bleeding at surgical site. 
or

BAY 2880376 / 21069 
Version 1.0 / 22 Aug 2019                     Page 51 of 61 
 
o Non-plausibility, e.g., the participant is struck by an automobile when there 
is no indication that the drug caused disorientation that may have caused 
the event; cancer developing a few days after the first drug administration. 
An assessment of “yes” indicates that that the AE is reasonably associated with the use of 
the study treatment. 
• The investigator will use clinical judgment to determine the relationship. 
• Alternative causes, such as underlying disease(s), concomitant therapy, and other 
risk factors, as well as the temporal relationship of the event to study intervention 
administration will be considered and investigated. 
• The investigator will also consult the Investigator’s Brochure (IB) and/or Product 
Information, for marketed products, in his/her assessment. 
• For each AE/SAE, the investigator must document in the medical notes that he/she 
has reviewed the AE/SAE and has provided an assessment of causality. 
• There may be situations in which an SAE has occurred and the investigator has 
minimal information to include in the initial report. However, it is very important 
that the investigator always make an assessment of causality for every event 
before the initial transmission of the SAE data. 
• The investigator may change his/her opinion of causality in light of follow-up 
information and send an SAE follow-up report with the updated causality 
assessment. 
• The causality assessment is one of the criteria used when determining regulatory 
reporting requirements. 
Causal relationship to protocol-required procedure(s) 
The assessment of a possible causal relationship between the AE and protocol-required 
procedure(s) is based on the question whether there was a “reasonable causal relationship” 
to protocol-required procedure(s). 
Possible answers are “yes” or “no” 
Action taken with study intervention 
Any action on study treatment to resolve the AE is to be documented using the categories 
listed below. 
The study treatment action should be recorded separately for each study treatment as 
detailed in the CRF/eCRF data collection system. 
• Drug withdrawn 
• Drug interrupted 
• Not applicable 
• Unknown

Other specific treatment(s) of adverse event 
• None 
• Remedial drug therapy 
• Other 
Outcome of adverse event 
The outcome of the AE is to be documented as follows:  
• Recovered/resolved 
• Recovering/resolving 
• Recovered/resolved with sequelae 
• Not recovered/not resolved 
• Fatal 
• Unknown 
Follow-up of AEs and SAEs 
• The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated to elucidate the nature 
and/or causality of the AE or SAE as fully as possible. This may include additional 
laboratory tests or investigations, histopathological examinations, or consultation 
with other health care professionals. 
• New or updated information will be recorded in the originally completed CRF. 
• The investigator will submit any updated SAE data to the sponsor within 24 hours 
of receipt of the information.

Reporting of SAEs 
 
SAE Reporting to the Sponsor via Paper CRF/Complementary pages 
• 
Email or facsimile transmission of the SAE paper CRF as well as the 
complementary pages provided is the preferred method to transmit this 
information to Bayer’s Pharmacovigilance department (see Section 
8.3.5). 
• 
In rare circumstances and in the absence of facsimile equipment, 
notification by telephone is acceptable with a copy of the SAE data 
collection tool sent by overnight mail or courier service. 
• 
Initial notification via telephone does not replace the need for the 
investigator to complete and sign the SAE CRF and complementary 
pages within the designated reporting time frames.

Appendix 4: Contraceptive Guidance and Collection of Pregnancy 
Information 
Definitions: 
Woman of Childbearing Potential (WOCBP) 
A woman is considered fertile following menarche and until becoming post-menopausal 
unless permanently sterile (see below). 
If fertility is unclear (e.g., amenorrhea in adolescents or athletes) and a menstrual cycle cannot 
be confirmed before first dose of study intervention, additional evaluation should be 
considered. 
Women in the following categories are not considered WOCBP 
1. 
Premenarchal 
2. 
Premenopausal female with 1 of the following: 
• Documented hysterectomy 
• Documented bilateral salpingectomy 
• Documented bilateral oophorectomy 
For individuals with permanent infertility due to an alternate medical cause other than the 
above, (e.g., mullerian agenesis, androgen insensitivity), investigator discretion should be 
applied to determining study entry. 
Note: Documentation can come from the site personnel’s: review of the participant’s medical 
records, medical examination, or medical history interview. 
 
1. 
Postmenopausal female 
• A postmenopausal state is defined as no menses for 12 months without an alternative 
medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal 
range may be used to confirm a postmenopausal state in women not using hormonal 
contraception or hormonal replacement therapy (HRT). However, in the absence of 12 
months of amenorrhea, confirmation with more than one FSH measurement [insert 
threshold if required (>40 IU/L or mIU/mL) or remove to allow for flexibility with 
different local thresholds for defining postmenopausal state] is required.  
• Females on HRT and whose menopausal status is in doubt will be required to use one 
of the non-estrogen hormonal highly effective contraception methods if they wish to 
continue their HRT during the study. Otherwise, they must discontinue HRT to allow 
confirmation of postmenopausal status before study enrollment. 
• The investigator will collect pregnancy information on any female participant who 
becomes pregnant while participating in this study. Information will be recorded on 
the appropriate form and submitted to the sponsor within 24 hours of learning of a 
participant's pregnancy.

• The participant will be followed to determine the outcome of the pregnancy. The 
investigator will collect follow-up information on the participant and the neonate, after 
obtaining the signed informed consent from both parents, unless local law or specific 
circumstances of the respective case allow otherwise, and the information will be 
forwarded to the sponsor. Generally, follow-up will not be required for longer than 6 
to 8 weeks beyond the estimated delivery date. Any termination of pregnancy will be 
reported, regardless of fetal status (presence or absence of anomalies) or indication for 
the procedure. 
• While pregnancy itself is not considered to be an AE or SAE, any pregnancy 
complication or elective termination of a pregnancy will be reported as an AE or SAE. 
A spontaneous abortion is always considered to be an SAE and will be reported as 
such. Any post-study pregnancy related SAE considered reasonably related to the 
study intervention by the investigator will be reported to the sponsor as described in 
Section 8.3.5. While the investigator is not obligated to actively seek this information 
in former study participants, he or she may learn of an SAE through spontaneous 
reporting.  
• Any female participant who becomes pregnant while participating in the study will 
discontinue study intervention or be withdrawn from the study. 
 
Collection of Pregnancy Information: 
Male participants with partners who become pregnant  
• The investigator will attempt to collect pregnancy information on any male 
participant’s female partner who becomes pregnant while the male participant is in 
this study. This applies only to male participants who receive study intervention. 
• After obtaining the necessary signed informed consent from the pregnant female 
partner directly, the investigator will record pregnancy information on the appropriate 
form and submit it to the sponsor within 24 hours of learning of the partner’s 
pregnancy. The female partner will also be followed to determine the outcome of the 
pregnancy. Information on the status of the mother and child will be forwarded to the 
sponsor. Generally, the follow-up will be no longer than 6 to 8 weeks following the 
estimated delivery date. Any termination of the pregnancy will be reported regardless 
of fetal status (presence or absence of anomalies) or indication for the procedure. 
Female Participants who become pregnant  
• The investigator will collect pregnancy information on any female participant who 
becomes pregnant while participating in this study. Information will be recorded on 
the appropriate form and submitted to the sponsor within 24 hours of learning of a 
participant's pregnancy.

TOOL.ST.101-01.02 Statistical Analysis Plan Template 
CONFIDENTIAL 
4.1.1 
Schedule of Visits and Assessments 
The schedule of assessments can be found in Section 1.3 of the protocol. 
4.1.2 
Method of Assigning Subjects to Treatment Groups 
On Day 1, participants will be assigned a unique number (randomization number) in ascending 
numerical order at the study site. The randomization number encodes the participant’s 
assignment to one of the seven (7) arms of the study, according to the randomization schedule 
generated prior to the study by the Sponsor. Each participant will be dispensed blinded study 
intervention, labeled with his/her unique randomization number, throughout the study. 
4.1.3 
Blinding 
Participants enrolled in the trial, investigators and their staff involved in protocol procedures or 
who are involved in data collection, data entry and data analysis will be blinded to the identity of 
the treatments until the database is locked. The study monitor will conduct product 
accountability after database lock. To preserve blinding, participants will be blindfolded during 
administration of study medication. Study drug will be dispensed by an unblinded study team 
member based on the randomization schedule. That team member may have no other role in the 
study conduct and may not reveal the study drug’s identity to any members of the blinded study 
team. 
Sponsor will supply study medication in bulk containers. Selection of the proper dose for an 
individual participant will be performed by an unblinded study team member using the provided 
randomization schedule. The unblinded study team member will withdraw the appropriate study 
medication from the bulk container and transfer it to a dispensing cup. All study interventions 
must be administered as 2 tablets per participant. Some study interventions require the addition 
of a placebo tablet. The unblinded study team member will then bring the study medication to 
the treatment room where it will be dispensed to the participant by the study team member. The 
unblinded study team member should have no other responsibilities in the study.
