All treatments will be administered via a
 jet nebulizer using the
 
compressor. 
Subjects who are currently on a stable dose of inhaled steroids will continue the use of these 
medications throughout the course of the study. 
Subjects who are currently using LABA monotherapy (other than formoterol) will be 
switched to formoterol for the duration of the study. Those subjects on ICS/LABA fixed 
dose combinations must be able to switch to an identical dose of ICS monotherapy 
(or equivalent) to be eligible to enroll in the study. 
Screening will involve either one or two visits, depending on whether a washout period is 
required. The first visit will be an Initial Screening Visit (Visit 1A) when informed consent 
will be obtained and the subject’s existing COPD medication will be assessed to decide 
whether any adjustments are required to comply with the requirements of the protocol. The 
subject will start a washout period only after signing the informed consent form.  
After completing the washout (if required), the subject will return for further screening 
assessments, including an Ipratropium Reversibility Visit (Visit 1B), electrocardiograms 
(ECGs) and vitals. It is only necessary to conduct the Initial Screening Visit (Visit 1A) and 
Ipratropium Reversibility Visit (Visit 1B) as separate visits if a washout is required. If a 
washout period is not required, these two visits may be performed as one visit.  
If a washout period is required, the time from the Initial Screening Visit (Visit 1A) to 
Visit 1B will be at least 48 hours and no longer than 7 days.  
At the Ipratropium Reversibility Visit (Visit 1B), the FEV1 response to a nebulized dose of 
ipratropium (500 mcg) will be tested to determine the subject’s reversibility status and 
GOLD category for airflow limitation.  
All remaining inclusion and exclusion criteria will be reviewed at this Visit 1B 
All subjects will be issued study-specific rescue medication (albuterol metered-dose inhaler 
or MDI) for use throughout the screening period. Subjects will be advised to avoid use of 
their rescue albuterol medication for at least 6 hours prior to each visit. 
Subjects will come in 2 to 7 days after Screening for Visit 2 (Day 1 of dosing). Eligible 
subjects will be randomized to one of two treatment groups in the study.  
The treatment period will involve 3 visits: 
• Visit 2 (Day 1) 
• Visit 3 (Day 21) 
• Visit 4 (Day 42) 
On visit days, subjects will attend the clinic for assessment of pre-dose vital signs, labs, 
ECGs,
 and review of AEs and concomitant medications. Subjects 
will administer study medication under supervision at all clinic visits to assess nebulizer 
technique and to correct and retrain as required. ECGs and vital signs will be measured 
60 minutes pre-dose and 10 minutes post-dose at these visits.

 On all visits, subjects will return the unused vials of 
study medication and the study-specific rescue medication they have been issued.  
At Visit 3 (Day 21), subjects will return for in-clinic dosing and
.   
Visit 3 will have a visit window of ±7 days. ECGs will be performed after the final 
supervised dose of the sequential administration of revefenacin (or placebo) and then 
formoterol  at 10 minutes postdose, which should be near the peak plasma level of 
formoterol.  The site will instruct the patient on how to mix the two solutions of study 
medication as a combined solution in the nebulizer.  Subjects will administer the study 
drugs as a combined solution for the remainder of the treatment period (Day 22 to 42).   
Subjects will return to clinic for Visit 4 (Day 42) for in-clinic supervised dosing 
 
.  Visit 4 will have a visit window of ±7 days. ECGs will be 
performed after the supervised final dose of the combined administration of revefenacin (or 
placebo) plus formoterol at 10 minutes postdose, which should be near the peak plasma 
level of formoterol.   
Visit 5 will be a follow up phone call to take place 7 (±2) days after Visit 4 (Day 42) to 
assess the subject for any adverse events or changes in concomitant medications. 
Subjects who experience moderate or severe acute exacerbations of COPD (AECOPD) will 
not be allowed to continue and will be withdrawn from the study.  
Duration of Study Participation: Up to 63 days (including screening and any required 
washout period). 
Number of Subjects per Group: Approximately 60 subjects will be enrolled into each of 
two treatment groups in a blinded 1:1 ratio (total of approximately 120 subjects).  
Study Population: 
Patients with moderate- to-very severe COPD who meet the criteria for study enrollment.  
Inclusion Criteria  
1. Subject is a male or female subject 40 years of age or older (age at Visit 1A). 
2. Subject is willing and able to provide signed and dated written informed consent to 
participate at Visit 1A prior to initiation of any study related procedures.  
3. Subject is capable of performing reproducible spirometry maneuvers as described 
by current American Thoracic Society (ATS) Guidelines and has a post-ipratropium 
FEV1/FVC ratio <0.7 at Visit 1B.  
4. Subject has moderate-to-very severe stable COPD with a post-ipratropium FEV1 
less than 80% of predicted normal at Visit 1B and a post-ipratropium FEV1 
>700 mL at Visit 1B. 
5. Subject has a current or past cigarette smoking history (or equivalent for cigar or 
pipe smoking history) of at least 10 pack-years.

6. Subject must be willing and able to attend study visits according to the visit 
schedule and adhere to all study assessments/procedures. 
7. Females of either child bearing potential or non-child bearing potential as follows: 
• Females of childbearing potential must have documentation of a negative urine 
pregnancy test at Visit 1B and again at Visit 2 (prior to randomization) if Visit 2 
is > 7 days after Visit 1B. If a urine pregnancy test is positive, it must be 
confirmed via a second urine pregnancy test. All female subjects of childbearing 
potential must agree to use a highly effective method of birth control during the 
study and for at least 1 month after completion of study drug dosing.  
− A highly effective method of birth control is defined as one that results in a 
low failure rate (i.e., <1% per year) when used consistently and correctly, 
such as condom + diaphragm, condom + spermicide, diaphragm + 
spermicide, or intrauterine device [IUD] with documented failure rate of 
<1% per year, or oral/injectable/implanted hormonal contraceptives used in 
combination with an additional barrier method.  
− Females are considered to be not of childbearing potential if they have had a 
total hysterectomy and/or bilateral tubal ligation (documentation for either 
must be provided before enrollment) or are at least 2 years postmenopausal 
(>24 months since last menstrual period).  
Exclusion Criteria: 
1. Females who are pregnant, planning to become pregnant, or breastfeeding during 
the study. 
2. Subject has a significant respiratory disease or disorder other than COPD that, in the 
opinion of the investigator, would interfere with the interpretation of data from this 
study including, but not limited to, restrictive lung disorders, benign or malignant 
tumors of the lung, chronic pulmonary infections such as tuberculosis, occupational 
lung disease such as silicosis or asbestosis, inflammatory disorders of the lung, 
alpha-1-antitrypsin deficiency, and/or abnormalities of the chest wall or musculature 
(e.g., scoliosis, myasthenia gravis, phrenic nerve palsy).  
3. Subject has a history of cancer of any organ, treated or untreated in the 5 years prior 
to Visit 1A (excludes localized basal cell or squamous cell carcinoma of the skin; 
localized prostate cancer in situ of grade 1; localized cervical cancer in situ of 
grade 0). 
4. Subject has a concurrent disease or condition that, in the opinion of the investigator, 
would interfere with study participation or confound the evaluation of safety, 
tolerability, or pharmacokinetics of the study drug. 
5. Subject has a history of reactions or hypersensitivity to inhaled or nebulized 
anticholinergics, short-acting beta-agonists and long-acting beta-agonists.

INTRODUCTION 
Pharmacologic treatment of chronic obstructive pulmonary disease (COPD) with 
bronchodilators is central to the management of both the symptoms and the long term risks of 
the condition. Long-acting inhaled bronchodilators are convenient and may be more effective 
for long-term symptom relief than short-acting bronchodilators; accordingly, 
widely-accepted treatment guidelines such as those produced by the Global Initiative for 
Chronic Obstructive Lung Disease (GOLD) recommend the use of long-acting muscarinic 
antagonist (LAMA) bronchodilators as first-line therapies for subjects with persistent COPD 
symptoms1.  
The use of dual bronchodilation has increasingly been recommended for the treatment of 
COPD. Recent GOLD guidelines have advocated stepping from monotherapy bronchodilator 
therapy to dual bronchodilator therapy for patients who remain symptomatic. More recently, 
the IMPACT study has demonstrated that triple therapy may have benefit above either 
ICS/LABA therapy or LAMA/LABA therapy.

1.2. 
Nonclinical Profile 
Revefenacin is a novel, long-acting, anti-muscarinic agent being developed as an inhalation 
solution for administration via standard jet nebulizer for the treatment of COPD.  A review of 
the nonclinical profile of revefenacin can be found in the current version of the revefenacin 
Investigator’s Brochure (IB). A brief summary of the pertinent findings follows this section. 
 is a long-acting beta-2 adrenergic receptor agonist that is United States Food 
and Drug Administration (FDA) approved for the nebulized treatment of COPD. For 
additional information on the efficacy and safety of 
Inhalation Solution refer to 
prescribing information.

 Overall, the pharmacology of revefenacin, when 
administered into the lungs, is consistent with that of a long-acting muscarinic antagonist and 
demonstrates good selectivity for lung versus systemic effects.  
Safety pharmacology studies for revefenacin included assessments of potential effects on 
cardiovascular and respiratory function and for potential neurobehavioral effects. These 
studies are summarized in the IB. 
1.2.2. 
Toxicology 
The toxicology assessment of revefenacin included single-dose toxicity, repeated-dose 
toxicity, genotoxicity, reproductive and developmental toxicity, and local tolerance studies. 
The results of these studies are summarized in the IB.

Risks and Benefits 
Subjects participating in this study may be at risk of experiencing adverse events related to 
muscarinic antagonism, including headache, mouth dryness, constipation, blurred vision, 
dizziness and urinary retention.  
Subjects participating in this study may experience discomfort due to blood draws for 
laboratory testing.     
Clinically significant bronchodilation has been observed in each of the study populations of 
COPD subjects thus far in the development program. Two replicate phase 3 efficacy studies 
 with a 3-month treatment period have demonstrated that the 88 mcg and 
175 mcg doses of revefenacin were generally well-tolerated, with comparable rates of 
adverse events and serious adverse events across all treatment groups (active and placebo). 
The most commonly reported adverse events, across both trials and across all revefenacin 
treatment groups were COPD exacerbation, nasopharyngitis, cough, dyspnea and headache. 
There were no reports of blurred vision, narrow-angle glaucoma or worsening of urinary 
retention, all of which are commonly reported adverse events for this class of medication. In 
addition, reports of dry mouth were < 0.5% in the revefenacin treatment arms.  A long term 
safety study 
with a 1-year treatment period revealed a similar safety profile to what 
was observed to the efficacy studies. 
Further detail regarding the safety profile for revefenacin is available in the revefenacin IB.

OBJECTIVES 
The primary objective of the study is as follows: 
• To characterize the safety and tolerability of once-daily revefenacin inhalation 
solution when dosed sequentially with twice-daily formoterol inhalation solution 
 compared to monotherapy 
 in a 
population of patients with moderate-to-very severe COPD over 21 days.  
The secondary objective of this study is: 
• To characterize the safety and tolerability of dosing a mixture of revefenacin 
inhalation solution and formoterol compared to dosing a mixture of placebo and 
formoterol in a population of patients with moderate-to-very severe COPD over 
21 days.

Study Endpoints  
The primary and secondary endpoints of this study will assess the long-term safety and 
tolerability of revefenacin in the treatment of COPD: 
• Frequency and severity of adverse events, including COPD exacerbations 
• Vital signs  
• Clinical laboratory evaluations 
• 12-lead ECG changes from baseline   
• Heart rate (as measured by ECG) 
The exploratory endpoints of this study 
 
 
 
 
3.5. 
Minimization of Bias  
Bias will be minimized through the use of randomization and a double-blind study design, 
with respect to revefenacin and placebo.   
3.5.1. 
Blinding 
All study subjects, study investigators and their staff, and the Sponsor’s staff involved in the 
conduct of the study will be blinded to treatment assignment with regard to revefenacin and 
placebo.  Subjects will be assigned in random order to revefenacin or placebo according to 
the randomization schedule. The only personnel who will have access to the randomization 
schedule before database lock are: 
• The nominated personnel at the Contract Research Organization responsible for 
generation of the randomization schedule. 
In the event of an untoward safety observation, the investigator may unblind a subject’s 
treatment assignment using the randomization and treatment supply management (RTSM). 
If possible, the investigator should first contact the Theravance Clinical Study Director 
before unblinding. The blind should be broken only if knowledge of the subject’s study 
medication would affect subsequent treatment and such knowledge is required for the clinical 
management of the subject. Any investigator unblinding will be documented within the 
appropriate section of the subject’s case report from (CRF) and will be captured in the 
RTSM.  
Unblinding of individual study subjects or site staff on the basis of results from the study 
procedures (i.e., self-unblinding) is not considered to be either an expected or likely event.

STUDY DRUGS 
All study drugs supplied by the Sponsor must be stored in a secure location accessible only to 
designated study personnel. The assignment of subjects to one of the treatment groups will be 
accomplished by randomizing the subject through the RTSM. Each drug kit will contain a 
unique kit number which will be provided by the RTSM on Day 1 to identify the study drug 
kits to dispense to a particular subject.  
More information regarding study drug dispensing, administration, handling and storage are 
provided in a separate Pharmacy Manual.

Detailed instructions for administration will be provided in the Pharmacy Manual.  
5.1.2. 
Formoterol 
Formoterol will be provided in a carton containing 30 foil wrapped vials each containing 
2 mL of a solution of 20 mcg/2 mL formoterol fumarate for inhalation by nebulization.   
Formoterol should be stored in a secure location at room temperature (2°C to 25°C or 36°F 
to 77°F).    
Detailed instructions for administration will be provided in the Pharmacy Manual.  
5.2. 
Dosage and Administration 
5.2.1. 
Revefenacin 
Revefenacin will be administered immediately prior to administration of formoterol on the 
morning of Day 1 in the clinic. This will continue each day at home until Day 21.  On the 
morning of Day 21 the subject will not administer the dose at home since this dose will be 
administered at the clinic. The subject will take the jet nebulizer, compressor and study drug 
home where dosing will occur every morning at approximately the same time and will be 
within the window of 6 am and 11 am.  Revefenacin will be administered immediately before 
formoterol each day.  Formoterol will be also be administered in the evening. 

Protocol 0167, Amendment 1 
Version 1.0, 16APR2018 
Revefenacin 
Page 32 of 70 
 
Confidential – Property of Theravance Biopharma, Inc. 
Training on the home use of the nebulizer will take place after the subject is randomized on 
Day 1 prior to discharge from the clinic. Subjects will be trained to administer the study drug 
until nebulization of the study drug solution is complete, which takes approximately 
10 minutes and is evidenced by “spluttering” of the nebulizer. Administration will be once 
daily in the morning at approximately the same time each day and the time of administration 
will be recorded by the subject in their diary. This time will be chosen based on convenience 
for the subject and will remain the same for the duration of the study. The subject may 
receive additional instruction at the site based on the judgment of the investigator. Additional 
information on the training of the subject on home nebulization is contained in the Pharmacy 
Manual. 
5.2.2. 
Formoterol 
Formoterol will be sequentially administered on the morning of Day 1 in the clinic, 
i.e., immediately after the administration of revefenacin.  This will continue each day at 
home until Day 21.  On the morning of Day 21 the subject will not administer the dose at 
home since this dose will be administered at the clinic.  Formoterol will also be administered 
approximately 12 hours after the morning dose each evening.  
At the end of the Day 21 visit, training will be provided to the subject on how to administer 
the revefenacin and formoterol as a combined solution, rather than sequentially, as a single 
nebulization session.  The first dose of the combination of revefenacin and formoterol will 
not begin however until the next morning at home on Day 22 and continue until Day 41.  
On the morning of Day 42 the subject will not administer the dose at home since this dose 
will be administered at the clinic. 
Formoterol will be administered every evening throughout the study from Day 1 until 
Day 41.  The time of the evening administration will be within the window of 6 pm and 
11 pm.   
The time of administration of the morning dose of revefenacin and formoterol (either 
sequentially or combined), and the evening dose of formoterol, will be recorded by the 
subject in their diary.  Refer to the package insert for further information. 
5.2.3. 
Agents for Rescue or Responsiveness Testing 
5.2.3.1. 
Ipratropium 
Ipratropium will be provided as a solution for administration via jet nebulizer for 
responsiveness testing during screening, at a dose of 500 mcg.  Refer to the package insert 
for further information. 
5.2.3.2. 
Albuterol 
All patients will be supplied with study-specific rescue medication (albuterol MDI) at 
Visit 1A for use throughout the remainder of the study.  Subjects will be advised to avoid use 
of their rescue medication for at least 6 hours prior to each visit.   
Subjects will return the albuterol MDI at each of the following study visits (Visit 2, Visit 3 
and Visit 4).  Additional albuterol will be dispensed as needed. 

Protocol 0167, Amendment 1 
Version 1.0, 16APR2018 
Revefenacin 
Page 33 of 70 
 
Confidential – Property of Theravance Biopharma, Inc. 
The subject will be allowed to retain their albuterol MDI at the end of the study for their own 
use. 
Refer to the package insert for further information. 
5.3. 
Treatment Compliance 
Compliance will be assessed in study subjects when accountability is performed as described 
in the next section. Compliance will be defined as subjects who are considered to have 
received 80-120% of the total number of doses that should have been administered in 
between study visits. 
Compliance outside the 80-120% range will be documented in the electronic CRF (eCRF) as 
to reasons why, the number of doses that were outside this range, and whether any adverse 
event occurred as a result of the non-compliance.  
5.4. 
Drug Accountability and Reconciliation 
The investigator or designee is responsible for maintaining accountability records for all 
study drug(s) received from the Sponsor, in accordance with applicable government 
regulations and study procedures. The accountability record will include entries for receipt, 
distribution or dispensing, and the on-site destruction or return of the material(s) as specified 
by the sponsor. Unused and expired study drugs will be disposed of in accordance with 
written instructions from Sponsor. 
Study drug accountability will be performed at Visit 3 (Day 21), Visit 4 (Day 42) and any 
unscheduled visit or early termination visit where study drug is returned, to document 
compliance with the dosing regimen. Subjects will be instructed to bring back all remaining 
study drug and all study drug packaging at each study visit for drug accountability. 
Treatment compliance will be assessed by subtracting the number of unused returned foil 
pouches from number of foil pouches that were supplied to the subject (for revefenacin and 
formoterol).  If a subject does not return the unused foil pouches, it will be assumed that the 
subject administered the study drug. If a subject misses recording any dose of study drug 
based on the subject’s diary, the site personnel should discuss the missing entries to 
determine if the missing entries are due to not recording the administration in the diary and 
make any necessary corrections to the diary while the subject is on site. Discrepancies 
between the subject’s diary and the count of returned study drug should be documented in the 
source documents. 
Albuterol count will be not be captured for this study.  Subjects should return their albuterol 
inhaler(s) at each study visit, and returns should be documented on the accountability logs.  
Subjects will be allowed to retain their albuterol MDI at the end of the study for their 
own use.

STUDY PROCEDURES 
6.1. 
Schedule of Study Procedures 
The schedule of study procedures is summarized in (Table 1). 
Throughout the study, investigators should conduct the order of the assessments for each 
study visit as indicated in the study procedures and strive to maintain consistency in this 
order. All study procedures for a visit must be completed on the same day. Any missed visits, 
test not done, or procedures that are not conducted must be reported as such on the eCRFs.  
The scheduling of Visit 3 (Day 21 ± 7 days) and Visit 4 (Day 42, ± 7 days) is based on the 
date of occurrence of Visit 2 (Day 1 of the treatment period when the subject is randomized). 
The follow-up phone call should be scheduled 7 days after Visit 4, with a ± 2 day visit 
window. 
6.2. 
Total Blood Volume 
The total volume of blood to be drawn from each subject for safety laboratory assessments 
(hemogram/hemoglobin and clinical chemistry) will be approximately 13.5 mL.  Additional 
samples may be necessary. 
6.3. 
Procedures by Visit 
Screening assessments and study procedures outlined in this section can only be performed 
after obtaining informed consent. Importantly, this includes any washout of a subject’s 
current medication for the purpose of participation in the study or changing a subject’s 
combination medication containing an inhaled steroid to inhaled steroid monotherapy 
  
Prior medical history should be obtained for the previous 2 years as part of screening the 
subject for eligibility into the trial.  If these records have not been obtained, then documented 
efforts to obtain these records must be present in the source documents. 
Participants in this study who, at the time of screening, are taking COPD medications 
requiring a washout will have two screening visits (1A and 1B). 
 
 
 
 
 
 
 
   
Subjects on LABAs (e.g., salmeterol, indacaterol, vilanterol, formoterol, arformoterol, 
olodaterol) must be prepared to stop these medications and switch to nebulized formoterol 
for the duration of the study. There is no washout period for LABAs, but the last dose of 
these medications should have been taken no sooner than 12 hours (for BID medications such 

Protocol 0167, Amendment 1 
Version 1.0, 16APR2018

as salmeterol, formoterol or arformoterol) or 24 hours (for QD medications such as vilaterol 
and indacaterol) before the randomization visit. 
Subjects on LABAs in combination with an ICS (e.g., fluticasone propionate, fluticasone 
fuorate, budesonide, ciclesonide, beclomethasone) will need to be switched to ICS 
monotherapy at the same or equivalent dose. Subjects must have been on a stable dose of ICS 
for at least 30 days prior to study entry. (A change from ICS/LABA to an equivalent ICS 
dose does not require this 30 day stability period). As with LABA monotherapy, if the 
subject is going to switch to an equivalent ICS monotherapy dose, this can occur on the day 
of randomization, assuming the last dose of LABA occurred as described above 
(12 or 24 hours prior to the visit as appropriate). 
Subjects on TRIPLE therapy would need to follow rules for washing out of the LAMA 
primarily, switching to a LABA and an ICS during this period of time, and then switching to 
study medication for the LABA on the day of randomization as described above. 
The first visit will be Screening Visit 1A.  Informed consent will be obtained and the 
subject’s existing COPD medication will be assessed to decide whether any adjustments are 
required to comply with the requirements of the protocol. If required, subjects will start a 
washout period only after signing the informed consent form. After completing the necessary 
washout period (if required) subjects will return for Screening Visit 1B within 7 days. 
If a washout period is not required then the first two screening visits (Visit 1A and Visit 1B) 
may be conducted as one visit.  The time period from Visit 1B (whether this is combined 
with Visit 1A or not) to randomization at Visit 2 will be 2 to 7 days.  Review of the 
spirometry at Visit 1B by the central spirometry vendor will take approximately 2 business 
days and must be completed to determine if the spirometry meets the eligibility criteria 
before the subject can be randomized. 
If a subject does not meet the eligibility criteria for reasons of a failed screening test due to a 
properly administered procedure, this test or procedure will not be allowed to be repeated and 
the subject should be screen failed. This includes spirometry, i.e., if a subject fails to meet 
any spirometry related criteria after the first attempt the subject should be screen failed.  
Repeat screening spirometry will only be considered if there is a technical issue (e.g., with 
the spirometer or with the software) or if the spirometry was not performed properly due to 
site error.  
6.3.1. 
Visit 1A (Screening Visit) – (performed up to 7 days before Visit 1B) 
The following procedures will be performed at this visit: 
• Written informed consent after the nature of the study has been explained and

for the 10 minutes post-dose spirometry will be +10 minutes only (with no – window). 
6.4.3.7. 
Pregnancy 
Urine pregnancy tests will be performed in women of child bearing potential. A positive 
urine pregnancy test will be confirmed with a second urine test. If the subject is an early 
termination or withdrawal, a urine pregnancy test will also be performed at the early 
termination visit.  
 
 
 
 
 
 
 
  
 
 
 
 
  
6.5. 
Concomitant Medications 
Inhaled maintenance steroid therapy will be continued at the allowed maintenance dose 
throughout the treatment and washout periods. Albuterol will be allowed as required 
(or “PRN”) during the study. Albuterol should be withheld for at least 6 hours before the

ECG
  
Only study supplied albuterol should be used during the subject’s participation in the study. 
If subjects have used albuterol within 6 hours of the ECG at the Visit 2, the visit should be 
rescheduled.  At each of the remaining visits, if this occurs, the visit will still be conducted, 
however this will be considered a protocol deviation. 
Subjects who are receiving a LABA or LABA/ICS (either QD or BID) may be enrolled into 
the study provided that the dose has been stable for at least 30 days prior to Screening and the 
steroid component is ≤1000 mcg/day equivalent to fluticasone propionate.  
Subjects on LABAs (e.g., salmeterol, indacaterol, vilanterol, formoterol, arformoterol, 
olodaterol) must be prepared to stop these medications and switch to nebulized formoterol 
for the duration of the study. There is no washout period for LABAs, but the last dose of 
these medications should have been taken no sooner than 12 hours (for BID medications such 
as salmeterol, formoterol or arformoterol) or 24 hours (for QD medications such as vilaterol 
and indacaterol) before the randomization visit. 
Subjects on LABAs in combination with an ICS (e.g., fluticasone propionate, fluticasone 
fuorate, budesonide, ciclesonide, beclomethasone) will need to be switched to ICS 
monotherapy at the same or equivalent dose. Subjects must have been on a stable dose of ICS 
for at least 30 days prior to study entry. (A change from ICS/LABA to an equivalent ICS 
dose does not require this 30 day stability period). As with LABA monotherapy, if the 
subject is going to switch to an equivalent ICS monotherapy dose, this can occur on the day 
of randomization, assuming the last dose of LABA occurred as described above (12 or 
24 hours prior to the visit as appropriate). 
The triple therapy will need to be switched to a LABA and ICS therapy during the 48 hour 
washout of the LAMA component.  Then on Day 1 the subject will be switched again to 
receive an equivalent ICS monotherapy as the study treatment administration will be in place 
of their LABA.  The ICS monotherapy should be continued for the duration of the treatment 
period.   
LABA and LABA/ICS drugs include the following examples:   
• fluticasone propionate/salmeterol combination product  
• budesonide/formoterol fumarate dihydrate combination product  
• fluticasone furoate/vilanterol combination product 
• mometasone/formoterol 
The initiation of new treatment for COPD during this study is strictly prohibited. If the 
subject experiences worsening of symptoms that requires additional therapy other than 
increased use of study supplied albuterol (i.e., an exacerbation of their COPD) they should be 
withdrawn from the study and, if the event qualifies, report this event as a serious adverse 
event.  
 
Subjects will be permitted to 
restart their routine medications after the completion of Visit 4.

Table 3: 
Severity Criteria for COPD Exacerbations 
COPD exacerbation is defined as a complex of respiratory symptoms (increase or new onset) 
of more than one of the following: cough, sputum, wheezing, dyspnea, or chest tightness with 
a duration of at least 3 days requiring treatment with SABAs, antibiotics, systemic steroids, 
or hospitalization. 
 
Severity of COPD exacerbation 
Criteria 
Mild 
A deterioration of COPD symptoms, in the judgment of 
the investigator, managed with an increased use of 
SABA but not requiring the use of antibiotics or oral or 
systemic corticosteroids. 
Moderate 
A deterioration of COPD symptoms, in the judgment of 
the investigator, based on any one of the following 
criteria: 
• 
An acute change in symptoms with purulent 
sputum requiring treatment with a course of 
antibiotics for lower airway disease 
• 
An acute change in symptoms requiring 
treatment with a course of oral steroid for lower 
airway disease 
• 
Subjects meeting the above criteria may receive 
treatment in a hospital setting as long as the 
duration of the visit is <1 day 
Severe 
A deterioration of COPD symptoms that results in 
hospitalization for emergency treatment of the COPD 
and the duration of the visit is ≥1 day.  
Subjects who experience a mild or moderate COPD exacerbation (one or more) may continue 
in the trial.  However, COPD exacerbations that are severe or result in a serious adverse 
event, will be discontinued from the trial.   
The Sponsor will be notified of all subject withdrawals. 
Subjects who discontinue study drug early because of an adverse reaction should be 
encouraged to continue their participation in the follow-up safety assessments. If a subject 
fails to return for scheduled visits, a documented effort must be made to determine the 
reason.

6.7.3. 
Study Discontinuation 
The Sponsor reserves the right to discontinue this study at any time for any reason. 
Certain circumstances may require the premature termination of the study, if the principal 
investigator and the Sponsor feel that the type, number and/or severity of AEs justify 
discontinuation of the trial, as for example, when several cases of similar serious adverse 
events (SAEs) considered related by both the investigator and the Sponsor occurs. The 
Sponsor reserves the right to discontinue this study at any time for any reason.  
6.8. 
Pregnancy 
If a female subject becomes pregnant during the study, the clinical study director 
(or designee) must be notified immediately and the subject discontinued from the study.  
The Investigator must report this to the Sponsor using the Pregnancy Reporting Form 
within 24 hours of becoming aware of the pregnancy. 
If not all information requested on the Pregnancy Reporting Form is available at the time 
of the initial report, follow-up reports must be completed and submitted within 24 hours of 
the Investigator’s becoming aware of any new information. The Investigator is required to 
follow up on the pregnancy until it has completed.  
Follow-up information regarding the outcome of the pregnancy and any postnatal sequelae in 
the infant will be required. The outcome of the pregnancy and the status of the newborn 
(if applicable) will be reported on the Pregnancy Reporting Form within 24 hours of the 
Investigator’s becoming aware of that information. 
6.9. 
COPD Exacerbations 
Exacerbations of COPD that are considered severe or result in a serious adverse event are 
cause for withdrawal from the study and will be captured as a reason for study termination.

ADVERSE EVENTS 
7.1. 
Definitions 
The definitions below are based on International Conference on Harmonization (ICH) 
guideline E2A, “Clinical Safety Data Management: Definitions and Standards for Expedited 
Reporting”. 
7.1.1. 
Adverse Events (AE) for the Purposes of This Study 
An AE is any untoward medical occurrence in a patient or clinical trial subject administered 
a pharmaceutical product that does not necessarily have to 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 a 
medicinal product, whether or not related to the medicinal product.  
• AEs may be new events 
• Preexisting events that increase in frequency, severity or change in nature or 
seriousness during or as a consequence of participation in clinical studies. 
• Pre- or post-treatment complications that occur as a result of a protocol-mandated 
procedure (such as a biopsy). 
• AEs may be clinically significant changes from baseline in physical examination, 
laboratory tests, or other diagnostic investigation (e.g., laboratory results, x-ray 
findings). 
• AEs may result from an overdose of the study medication.  
Whenever possible, the diagnosis (rather than a series of terms related to a diagnosis) should 
be recorded as the AE term. 
An AE does not include the following: 
• All COPD exacerbations (mild, moderate and severe) will be qualified as an 
Adverse Event. Please see definitions of COPD exacerbations in Table 3. 
• Medical or surgical procedures (such as surgery, endoscopy, tooth extraction, or 
transfusion); the condition that leads to the procedure is an adverse event 
• Preexisting diseases or conditions present or detected before signing an informed 
consent form that do not worsen 
• Situations where an untoward medical occurrence has not occurred (such as 
hospitalization for elective surgery or social and/or convenience admissions) 
• Overdose of either study drug or concomitant medication without any signs or 
symptoms, unless the subject is hospitalized for observation 
Any medical condition or clinically significant laboratory abnormality with an onset date 
prior to the time the subject signed the informed consent form is considered to be preexisting 
and should be documented in the medical history CRF. 

Protocol 0167, Amendment 1 
Version 1.0, 16APR2018 
Revefenacin 
Page 51 of 70 
 
Confidential – Property of Theravance Biopharma, Inc. 
Pregnancy is not an AE; however, if a female subject becomes pregnant during the conduct 
of the study, Theravance Biopharma will be notified according to the procedures for SAE 
reporting as outlined in Section 7.4.3.  Follow-up information regarding the outcome of the 
pregnancy and any fetal or neonatal sequelae will be obtained and documented. 
7.1.2. 
Serious Adverse Event (SAE) 
An SAE is defined as any untoward medical occurrence occurring at any dose that results in 
any of the following outcomes: 
• Death 
• Life-threatening situation.   “Life-threatening” refers to a situation in which the 
patient was at risk of death at the time of the event; it does not refer to an event 
which might have caused death if it were more severe. 
• Inpatient hospitalization or prolongation of existing hospitalization 
• Note:  “Inpatient hospitalization” means the subject has been formally admitted to 
a hospital for medical reasons, for any length of time. This may or may not be 
overnight. It does not include presentation and care within an emergency 
department. A scheduled hospitalization for a pre-existing condition that has not 
worsened during participation in the study does not meet this criterion. 
Pre-planned hospitalizations for an elective medical/surgical procedure, scheduled 
treatments, or routine check-ups do not meet this criterion. Complications that 
occur during hospitalizations are AEs. If a complication prolongs hospitalization, 
it is an SAE. 
• Congenital anomaly/birth defect in the offspring of a subject who received study 
drug 
• Important medical events that may not result in death, be immediately 
life-threatening, or require hospitalization, may be considered an SAE when, 
based upon appropriate medical judgment, they may jeopardize the subject and 
may require medical or surgical intervention to prevent one of the outcomes listed 
in this definition. Examples of such events are as follows: 
− Intensive treatment in an emergency room or at home for allergic 
bronchospasm 
− Blood dyscrasias or convulsions that do not result in hospitalization 
− Development of drug dependency or drug abuse 
7.1.3. 
Additional Considerations for Serious Adverse Events 
• Death is an outcome of an adverse event and not an adverse event in itself. Deaths 
of unknown cause for which the investigator cannot identify a cause of death will 
be captured as death of unknown cause or death not otherwise specified. 
• All deaths, regardless of cause, must be reported for subjects if the death occurs 
while the subject is participating in the study. 

Protocol 0167, Amendment 1 
Version 1.0, 16APR2018 
Revefenacin 
Page 52 of 70 
 
Confidential – Property of Theravance Biopharma, Inc. 
• “Occurring at any dose” does not imply that the subject is receiving study drug at 
the time of the event; dosing may have been given as treatment cycles or 
interrupted temporarily before the onset of the SAE, but may have contributed to 
the event. 
7.2. 
Clinical Laboratory Abnormalities and Other Abnormal 
Assessments as Adverse Events or Serious Adverse Events 
Abnormal laboratory findings (such as clinical chemistry or hematology) or other abnormal 
assessments (such as ECGs, X-rays, or vital signs) that are considered clinically significant in 
the judgment of the investigator must be recorded as AEs or SAEs if they meet the definition 
of an adverse event (or serious adverse event), as described in Sections 7.1.1 (Adverse Event) 
and 7.1.2 (Serious Adverse Event). 
If there are any AE questions, the investigator is encouraged to contact the Sponsor to 
discuss. 
7.3. 
Assessment of Adverse Events 
All AEs will be assessed by the investigator and recorded in the case report form, including 
the dates of onset and resolution, severity, relationship to study drug, outcome, and action 
taken with study medication. 
7.3.1. 
Severity 
The term “severe” is often used to describe the intensity (severity) of a specific event (as in 
mild, moderate, or severe myocardial infarction); the event itself, however, may be of 
relatively minor medical significance (such as severe nausea).  This is not the same as 
“serious,” which is based on patient/event outcome or action criteria usually associated with 
events that pose a threat to a subject’s life or functioning.  The severity of AEs will be 
assessed according to the following definitions:   
• Mild:  the AE is noticeable to the patient and/or the Investigator, but does not 
interfere with routine activity. 
• Moderate:  the AE interferes with routine activity, but responds to symptomatic 
therapy or rest. 
• Severe:  the AE significantly limits the patient’s ability to perform routine 
activities despite symptomatic therapy. 
7.3.2. 
Causal Relationship to Study Medication 
The Investigator’s assessment of causality is based on clinical judgment regarding the 
reasonable possibility that the study medication caused the event and may include 
consideration of some or all of the following factors: 
• Possible alternative causes of the AE, including the disease under treatment, 
co-morbid conditions, other drugs, and environmental factors. 
• The temporal association between drug exposure and onset of the AE.  

Protocol 0167, Amendment 1 
Version 1.0, 16APR2018 
Revefenacin 
Page 53 of 70 
 
Confidential – Property of Theravance Biopharma, Inc. 
• Whether the clinical or laboratory manifestations of the AE are consistent with 
known actions or toxicity of the study medication. 
• Whether the AE resolved or improved with decreasing the dose or stopping the 
study medication (“dechallenge”) or recurred or worsened upon re-exposure to the 
study medication (“rechallenge”).  
The causal relationship between the study medication and the AE will be described using one 
of the following categories: 
• Not Related:  Evidence exists that the adverse event has an etiology other than 
the study drug (such as a preexisting condition, underlying disease, intercurrent 
illness, or concomitant medication). 
• Related: A temporal relationship exists between the event onset and 
administration of the study drug. It cannot be readily explained by the subject’s 
clinical state or concomitant therapies and appears with some degree of certainty 
to be related based on the known therapeutic and pharmacologic actions of the 
drug. In case of cessation or reduction of the dose, the event abates or resolves 
and reappears upon rechallenge. It should be emphasized that ineffective 
treatment should not be considered as causally related in the context of adverse 
event reporting. 
7.4. 
AE Reporting and Recording 
7.4.1. 
AE Reporting 
Timely, accurate, and complete reporting and analysis of safety information from clinical 
trials is crucial for the protection of patients and is mandated by regulatory agencies.  
Sponsor has established standard operating procedures in compliance with regulatory 
requirements worldwide to ensure appropriate reporting of safety information.  All clinical 
trials sponsored by TBPH will be conducted in accordance with these procedures.  
7.4.2. 
AE and SAE Recording 
All AEs, regardless of seriousness, severity, or causal relationship to study medication, will 
be recorded from signing informed consent through the last study visit (or last subject contact 
in the case of a follow-up telephone call).  AEs will be recorded on the AE page of the CRF.  
SAEs, regardless of relationship to study medication will be recorded from signing informed 
consent through the last study visit (or last subject contact in the case of a follow-up 
telephone call).   Additionally, investigators may report SAEs assessed as related to study 
medication through 30 days following the last study visit (or last subject contact in the case 
of a follow-up telephone call). All SAEs will be recorded on both the SAE Report Form and 
the AE page of the CRF and should include the following:

Revefenacin 
Page 54 of 70 
 
Confidential – Property of Theravance Biopharma, Inc. 
Description of event:   
• Signs and symptoms due to a common etiology should be reported as a single 
diagnosis; for example, cough, runny nose, sneezing, sore throat, and head 
congestion would be reported as “upper respiratory infection”.   
• A diagnosis or description must be as specific and as complete as possible 
(e.g., “lower extremity edema” instead of “edema”).  
• Hospitalization or surgical procedures should not be used as adverse event terms 
(e.g., if a subject was hospitalized for cholecystectomy due to cholecystitis, the 
adverse event term should be recorded as cholecystitis, and not as the procedure, 
cholecystectomy).   
• “Death” should not be used as an adverse event term unless the cause of death is 
unknown.  For events with a fatal outcome, the cause of death should be the 
adverse event term  (e.g., if a subject died of an acute myocardial infarction, the 
adverse event term should be recorded as “Myocardial Infarction” and the event 
outcome as fatal).     
− Relationship to study medication: The Investigator will make an assessment of 
the causal relationship of the study medication to the AE using the guidelines 
in Section 7.3.2.  
− Severity: The severity of the AE will be assessed using the guidelines in 
Section 7.3.1. 
− Outcome:  The outcome of AEs will be recorded.   
− Therapeutic measures:  Measures taken for the treatment or management of 
the AEs will be recorded. 
7.4.3. 
SAE Reporting Timeline 
SAEs will be reported to Clinical Safety and Pharmacovigilance within 24 hours of the time 
the Investigator or his/her designee becomes aware that an SAE has occurred, whether or not 
the event is considered to be related to study medication.  If the initial SAE is reported by 
telephone, a written report signed by the Investigator must be submitted within 24 hours.   
The SAE Report Form must be completed in accordance with the SAE Report Form 
Completion Guidelines.  If all information on the SAE Report Form is not available at the 
time of the initial report, follow-up SAE reports will be completed and submitted.   
To report an SAE, complete and email or fax the Serious Adverse Event Report Form to the 
following:

For fatal or life-threatening events, fax copies of hospital case reports, autopsy reports, and 
other documents when requested. Additional information may be requested from the 
investigator to ensure the timely completion of accurate safety reports. 
An SAE may qualify for reporting to regulatory authorities if the SAE is possibly attributable 
to the study drug and is unexpected/unlisted based on the current revefenacin IB. In this case, 
all investigators will receive notification of the event. The investigator is responsible for 
notifying the Institutional Review Board or Ethics Committee and documenting the 
notification, as required by local regulatory authorities and in accordance with the local 
institutional policy. 
7.5. 
Adverse Event Follow-up 
A subject experiencing an AE or SAE will be followed by the investigator or his/her trained 
delegate(s) through the follow-up visit or until the investigator and/or the Sponsor has 
determined that the AE or SAE has resolved or a stable clinical endpoint is reached, 
whichever is longer. The Sponsor may request follow-up of certain adverse events until 
resolution and documentation of assessments made during this period. 
The investigator must take all therapeutic measures necessary for resolution of an SAE. 
Any medications necessary for treatment of the SAE must be recorded in the concomitant 
medication section of the case report form.

8.3. 
Analysis Sets 
The Safety analysis set will include all randomized subjects receiving at least one dose of 
study drug summarized by actual drug received. These subjects will be analyzed according to 
their actual treatment received, regardless of their randomized treatment. The Safety analysis 
set will be the primary analysis for safety analyses. 
The Intent-to-Treat (ITT) analysis set will include all randomized subjects.  Subjects in this 
set will be analyzed according to their randomized treatment assignments, regardless of 
treatment received.   
A per-protocol (PP) analysis will also be implemented and be considered supportive to the 
ITT analysis. The PP analysis set included all subjects in the ITT analysis set who did not 
violate the key inclusion/exclusion criteria through Day 42. Subjects who received the 
incorrect treatment (compared to their randomized treatment) at any time point will be 
excluded from this subset. For subjects who received proscribed medications during the 
42-days treatment period, all data collected after the first occurrence of receiving proscribed 
medication will be excluded from the PP analysis. The key inclusion/exclusion criteria 
pertaining to the PP analysis and the list of proscribed medications will be included in the 
statistical analysis plan (SAP).

Safety Analyses  
For all safety analyses, the safety analysis population will be used. 
Safety variables to be summarized include vital signs, adverse events, clinical laboratory 
results (hematology and chemistry), and corrected QT interval (QTcF) from standard safety 
digital ECGs. Vital signs will be summarized in terms of observed values and changes from 
baseline. 
8.5.1. 
Extent of Exposure 
A subject’s data for the extent of exposure to study drug will be generated from the study 
drug administration page of the CRF.  Dosing information for individual subjects will be 
listed.  Using drug administration data, estimates of exposure to revefenacin and/or 
formoterol will be summarized.  Dose discontinuations and reasons for study drug 
discontinuation will be listed and summarized. 
8.5.2. 
Adverse Event Data 
Adverse events will be coded to the preferred terms of the Medical Dictionary for Regulatory 
Activities (MedDRA®). Summaries will present by system organ class (SOC), preferred 
term (PT) and severity, the frequency and percentage of subjects reporting each observed 
event. 
Adverse events observed during the period from obtaining informed consent to the start of 
administration of study drug will be regarded separately from adverse events observed after 
study drug administration (i.e., treatment-emergent adverse events [TEAEs]). 
A TEAE will be defined as any AE that begins on or after the date of first dose of study drug 
up to the date of last dose of study drug plus the number of days in the follow-up period.  
AEs observed during the period from obtaining informed consent to the start of 
administration of study drug will be regarded separately from TEAEs. 
All AEs and all TEAEs will be listed by subject.  The frequency of subjects who experience 
TEAEs will be summarized overall and by treatment group.  AEs will also be summarized by 
relationship to treatment (study drug) and severity. 
A listing will be provided for all subjects who experience an SAE.  Data listings will also be 
provided for subjects who discontinued the study due to any AE, as well as for a SAE. 
8.5.3. 
Concomitant Medications 
Medications will be summarized both prior and during the treatment period. Medications will 
be summarized in the following classes, COPD bronchodilator, ICS and non-COPD 
medications.

Laboratory Data 
Laboratory data will be summarized in terms of observed values, changes from baseline, 
values relative to normal ranges, and changes from baseline relative to normal ranges. 
Listings will flag laboratory values that are outside of normal range. 
Clinical laboratory test results will be listed by subject. Reference ranges provided by the 
laboratory for each parameter will be used to evaluate the clinical significance of laboratory 
test results.  Values falling outside of the relevant reference range will be flagged, as 
appropriate, in the data listings.  Abnormalities in clinical laboratory test results will be listed 
in a separate listing.   
8.5.5. 
Vital Signs Data 
Vital Signs data will be summarized in terms of observed values (by time point), changes 
from baseline (by time point), and counts and percentages within appropriately defined 
categories (Table 4).

Treatment emergent ECG abnormalities are defined as those not present at baseline, or those 
that worsened after treatment, e.g., borderline at baseline, but were prolonged after treatment. 
QTcF {and QTcB} will also be summarized by the following categories, Normal (males 
<430, females <450), Borderline (males (≥430, <450); females (≥450, <470)) and Prolonged 
(males ≥450, females ≥470). 
When multiple values exist for the same nominal time point (e.g., triplicate reading), the 
average of the readings taken for ECG parameters will be used in the data analysis, including 
the outlier analysis stated below. 
There will be no imputation of missing data. Subjects without post-baseline measurement for 
a given treatment period will be excluded from the summary statistic (e.g., denominator of 
the summary statistic) for that time point.   
All recorded values for the ECG parameters will be presented in a by-subject listing. 
A separate listing of subjects with values of QTcF > 500 msec or an increase > 60 msec will 
be provided, as necessary. 
Cumulative distribution plots will be provided for maximum change in QTcF by day. 
8.6. 
Other Analyses 
For other analyses, the ITT population will be used. In select analyses, the PP and subgroup 
examination sets may be used.

STUDY ADMINISTRATION 
This study will be conducted in compliance with all applicable regulations. 
9.1. 
Principal Investigator Responsibilities 
Before beginning the study, the principal investigator (PI) at each site must provide to the 
Sponsor or its designee a fully executed and signed Form FDA 1572 and, if applicable, a 
financial disclosure form. For applicable studies, financial disclosure forms must also be 
completed for all subinvestigators who will be directly involved in the treatment or 
evaluation of research subjects in this study. (A subinvestigator is defined in ICH E6 as any 
individual member of the clinical study team designated and supervised by the investigator at 
a study site to perform critical study-related procedures and/or to make important 
study-related decisions [e.g., associates, residents, research fellows].) 
The PI will ensure the following: 
• He or she will conduct the study in accordance with the relevant, current protocol 
and will only make changes in a protocol after notifying the sponsor, except when 
necessary to protect the safety, rights, or welfare of subjects. 
• He or she will personally conduct or supervise the study. 
• He or she will inform any potential subjects, or any persons used as controls, that 
the drugs are being used for investigational purposes and he or she will ensure 
that the requirements relating to obtaining informed consent in 21 CFR Part 50 
and institutional review board (IRB) review and approval in 21 CFR Part 56 are 
met.  
• He or she will report to the sponsor adverse experiences that occur in the course 
of the investigation in accordance with 21 CFR 312.64. 
• He or she has read and understands the information in the Revefenacin IB, 
including potential risks and side effects of the drug. 
• His or her staff and all persons who assist in the conduct of the study are informed 
about their obligations in meeting the above commitments 
• He or she will ensure that adequate and accurate records in accordance with 
21 CFR 312.62 and to make those records available for inspection in accordance 
with 21 CFR 312.68. 
• He or she will ensure that the IRB/independent ethics committee (IEC) complies 
with the requirements of 21 CFR Part 56, and other applicable regulations, and 
conducts initial and ongoing reviews and approvals of the study. He or she will 
also ensure that any change in research activity and all problems involving risks 
to human subjects or others are reported to the IRB/IEC. Additionally, he or she 
will not make any changes in the research without IRB/IEC approval, except 
where necessary to eliminate apparent immediate hazards to human subjects. 
• He or she agrees to comply with all other requirements regarding the obligations 
of clinical investigators and all other pertinent requirements in 21 CFR Part 312.

9.2. 
Institutional Review Board/Independent Ethics Committee 
Before beginning study-specific research, the investigator will obtain written confirmation 
that the IRB, IEC, or Research Ethics Board (REB) is properly constituted and compliant 
with ICH and good clinical practice (GCP) requirements, applicable laws, and local 
regulations. A copy of the confirmation from the IRB/IEC/REB will be provided to the 
Sponsor or its designee. The protocol, informed consent form (ICF), IB, and any other 
appropriate written information provided to the subjects that the IRB/IEC/REB may require 
to fulfill its responsibilities will be submitted to the IRB/IEC/REB in advance of the study. 
The Sponsor or its designee must approve the ICF and all subject recruitment materials 
before they are submitted to the IRB/IEC/REB. The study will not proceed until appropriate 
documents from the IRB/IEC/REB confirming unconditional approval of the protocol and 
the ICF are obtained by the investigator and copies are received by the Sponsor or its 
designee. If possible, the approval document should refer to the study by study protocol title 
and the Sponsor study number, identify the documents reviewed, and include the date of the 
review and approval. The written approval of the IRB/IEC/REB will be retained as part of 
the study file. The study may proceed before approval of consent forms and other study 
documents translated to a language other than the native language of the clinical site, 
provided that written IRB/IEC/REB approval of the translated documents is obtained before 
they are used. Any amendments to the protocol should be reviewed promptly. 
The investigator must provide the appropriate periodic reports on the progress of the study to 
the IRB/IEC/REB and the Sponsor in accordance with local IRB/IEC/REB requirements and 
applicable governmental regulations, whichever is strictest. 
9.3. 
Informed Consent 
A properly written and executed ICF, in compliance with ICH E6 (GCP Guideline, 
Section 4.8), 21 CFR §50, and other applicable local regulations, will be obtained for each 
subject before enrollment of the subject into the study. The investigator will prepare the ICF 
or revise the template ICF and provide the documents to the Sponsor (or designee) for 
approval before submission to the IRB/IEC/REB. The Sponsor and the IRB/IEC/REB must 
approve the documents before they are implemented. 
The investigator will provide copies of the signed ICF to each subject (or the subject’s 
legally authorized representative) and will maintain the original in the subject’s record file. 
9.4. 
Data Recording and Quality Assurance 
As used in this protocol, the term case report form (CRF) should be understood to refer to 
either a paper form or an electronic data record or both, depending on the data collection 
method used. 
A CRF (approved by the Sponsor) is required and should be completed (in English) for each 
randomized subject. The investigator has ultimate responsibility for the accuracy, 
authenticity, completeness, and timely collection and reporting of all clinical, safety, and 
laboratory data entered on the CRFs and any other data collection forms. The investigator 
must review and sign the CRFs to attest that the data contained on the CRFs are correct. 

Protocol 0167, Amendment 1 
Version 1.0, 16APR2018 
Revefenacin 
Page 65 of 70 
 
Confidential – Property of Theravance Biopharma, Inc. 
Electronic data capture (EDC) technology will be used for this study. All clinical information 
requested in this protocol will be recorded on the electronic case report forms approved by 
the Sponsor, or via other data collection methods, e.g., electronic laboratory data transfer. 
Study site personnel will enter (in English) study data into the CRFs for each randomized 
subject. Training on the EDC application will be completed and documented before access to 
the EDC system is given. 
In the event of a CRF data change (e.g., correction of an error or addition of new 
information), corrections will be made to the CRF. Corrections to the CRFs, including the 
reason for change, will be automatically documented through the EDC system’s audit trail. 
The investigator is responsible for reviewing all CRFs, verifying them for accuracy, and 
approving them via an electronic signature. The investigator is designated as the signatory 
coordinating investigator. 
An electronic copy of the CRF casebooks will be sent to the site for retention with other 
study documents after full completion of the study, i.e., after database lock. 
The investigator is responsible for maintaining accurate, authentic, complete, and up-to-date 
records for each subject. The investigator is also responsible for ensuring the availability of 
any original source documentation related to the study (including any films, tracings, 
computer discs, tapes, and worksheets). In most cases the source is the subject’s medical 
record. Data collected on the CRFs must match the source documents. 
In some cases, the CRF may also serve as the source document. In these cases, a document 
should be available at the investigator’s site and clearly identify those data that will be 
recorded in the CRF and for which the CRF will stand as the source document. 
9.5. 
Document Retention 
Until otherwise notified by the Sponsor, an investigative site must retain in a controlled 
manner all study documents required by the Sponsor and by the applicable regulations. The 
investigative site must take measures to prevent accidental or premature destruction of 
essential documents, that is, documents that individually and collectively permit evaluation 
of the conduct of a study and the quality of the data produced, including paper copies of 
study records (e.g., subject charts) and any original source documents that are electronic, as 
required by applicable regulations. 
The investigator must consult the Sponsor representative before disposal of any study records 
and must notify the Sponsor of any change in the location or disposition of the study files. If 
an investigator retires, relocates, or for other reasons withdraws from the responsibility of 
keeping the study documents, custody must be transferred to a person who will accept the 
responsibility. The Sponsor must be notified in writing of the name and address of the new 
custodian and must approve this transfer of responsibility.

9.6. 
Confidentiality 
The investigator or designee must explain to each subject, before enrollment into the study, 
that, for evaluation of study results, the subject’s confidential medical information obtained 
during the study may be shared with the study sponsor, the study sponsor’s affiliated 
companies, the study sponsor’s designated service providers, regulatory agencies, and the 
institutional review board (IRB) or independent ethics committee (IEC). The investigator 
(or designee) is responsible for obtaining written permission to use confidential medical 
information in accordance with country-specific regulations (such as the Health Insurance 
Portability and Accountability Act in the United States) from each subject or, if appropriate, 
the subject’s legally authorized representative. If permission to use confidential medical 
information is withdrawn, the investigator is responsible for documenting that no further data 
from the subject will be collected. 
Subject medical information obtained during this study is confidential, and disclosure to 
unauthorized third parties is prohibited. The pertinent sections of data protection laws will be 
complied with in full. Study records containing subject information will only be identified by 
the subject identification number, subject initials, date of birth, and study number, and not by 
the subject’s full name, except the subject consent form, which is archived at the study center 
only. The subject’s name will not be used in any public report of the study. 
During the course of the study, a confidential subject identification list will be maintained by 
the investigator and archived at the investigative site. 
Before and during the conduct of the study, no study-related details may be disclosed, 
i.e., placed on the internet, published, or otherwise publicized, or provided to a third party 
without prior written permission from the Sponsor. The policy for publication of data after 
completion of the study is described in Section 9.9 (Publication). 
9.7. 
Access to Data and Documents 
Upon receipt of the subject’s permission, medical information may be given to his or her 
personal physician or other appropriate medical personnel responsible for his or her welfare. 
Study data recorded on the CRFs must be verifiable to the source data. All original 
recordings, laboratory reports, and subject records generated by this study must be available 
to the Sponsor, representatives of the Sponsor, the IRB/IEC/REB, and applicable regulatory 
authorities, and they may be used for submission to regulatory authorities. In addition, all 
source data should be attributable (signed and dated), consistent with local medical practice. 
The investigator must therefore agree to allow direct access to all source data. Subjects 
(or their legally authorized representatives) must also allow access to their medical records, 
and subjects will be informed of this and will confirm their agreement when giving informed 
consent.

9.8. 
Quality Control: Study Monitoring and Auditing 
Qualified individuals designated by the Sponsor will monitor all aspects of the study 
according to GCP and standard operating procedures (SOPs) for compliance with applicable 
government regulations. The investigator agrees to allow these monitors direct access to the 
clinical data and supplies, dispensing, and storage areas and, if requested, agrees to assist the 
monitors. The investigator and staff are responsible for being present or available for 
consultation during routinely scheduled site visits conducted by the Sponsor or its designees. 
Members of the Sponsor’s GCP Quality Assurance Department or designees may conduct an 
audit of a clinical site at any time during or after completion of the study. The investigator 
will be informed if an audit is to take place and advised as to the scope of the audit. 
Inspections and audits are typically carried out during the clinical and reporting phases of this 
study to ensure that the study is conducted and data are generated, documented, and reported 
in compliance with the protocol, GCP, written SOPs and applicable laws, rules, and 
regulations. 
Representatives of the FDA or other Regulatory Agencies, including IRB/IEC 
representatives may also conduct an audit of the study. If informed of such an inspection, the 
investigator should notify the Sponsor immediately. The investigator will ensure that the 
auditors have access to the clinical supplies, study site facilities, laboratory and all data 
(including original source documentation) and all study files are available, if requested. 
Noncompliance with the protocol, ICH, GCP, or local regulatory requirements by an 
investigator, institution, institution staff, or representatives of the Sponsor will lead to prompt 
action by the Sponsor to secure compliance. Continued noncompliance may result in 
termination of the investigator’s involvement in the study. The IRB/IEC/REB and relevant 
regulatory authority will be informed. 
9.9. 
Publication 
The Sponsor recognizes the importance of communicating medical study data and therefore 
encourages their publication in reputable scientific journals and presentation at seminars or 
conferences. The Sponsor will retain the ownership of the data collected in this study. The 
investigator will provide any proposed manuscript or abstract to the Sponsor before 
submission for publication or presentation of any results or data obtained in this study. 
Additional details of the processes of producing and reviewing reports, manuscripts, and 
presentations based on the data from this study will be described in the Clinical Study 
Agreement between the Sponsor and the investigator.
