1. PROTOCOL SYNOPSIS

Protocol Number:     ABC01
Title:               A Multi-Center, Randomized, Double-Blind, Placebo-Controlled Study
                     Comparing the Safety and Effectiveness of Drug A 20 mg Once Daily
                     Versus Placebo Using 24-Hour Ambulatory Blood Pressure Monitoring
                     (ABPM) In Patients with Mild to Moderate Hypertension.
Indication:          Mild to moderate hypertension.
Objectives:          1. The primary objective of the study is to compare the
                           antihypertensive effectiveness using change from Baseline in mean
                           seated office cuff diastolic blood pressure of Drug A 20 mg once
                           daily to placebo.
                     2. The secondary objective is to evaluate the safety of low-dose Drug
                           A compared to placebo and change from Baseline at Week 6 or end
                           of study in mean 24-hour and mean daytime ambulatory Diastolic
                           Blood Presssure (from time of dosing until 8:00PM) as measured by
                           ABPM.
Study Design:        The study will employ a randomized, double-blind design in patients with
                     mild to moderate hypertension. The study includes a 3- to 4-week
                     single-blind placebo run-in phase and a 6-week double-blind treatment
                     phase.
Treatments:          All patients will receive placebo tablets once daily for 3 – 4 weeks during
                     the single-blind, run-in phase. During the double-blind treatment phase,
                     patients will be randomized in a 1:1 ratio to receive either Drug A 20 mg
                     or placebo tablets once daily for 6 weeks.
Procedures/Visits:   Study visits will be scheduled to fit within the window for trough blood
                     pressure (BP) measurements (i.e., prior to next dose and between 22–26
                     hours after previous dose [24±2 hours]).
Study Population:    Approximately 300 patients at approximately 10 sites will be enrolled
                     into the placebo run-in phase. It is expected that 20% of patients will not
                     qualify for randomization based on office BP entry criteria and an
                     additional 25% of patients will not qualify based on ABPM entry criteria.
                     The study will randomize approximately 180 patients into the
                     double-blind treatment. The study population will include males and
                     females ≥ 18 years of age with mild to moderate hypertension (defined as
                     a seated diastolic blood pressure (DBP) ≥ 95 mmHg and ≤ 110 mmHg).
Efficacy Measures:   Primary Endpoint: The primary efficacy endpoint is the change from
                     Baseline in mean seated office cuff DBP (24±2 hours) at Week 6 or end
                     of study.

                     Secondary Endpoints:

                                                                                    Confidential


                             Change from Baseline in seated office systolic blood pressure (SBP)
                              at Weeks 2, 4, 6 or end of study and DBP at Weeks 2 and 4 or end of
                              study,
                         Change from Baseline to Week 6 or end of study in mean 24-hour
                              and mean daytime ambulatory DBP (time of dose until 8:00 PM) as
                              measured by ABPM,
                         Change from Baseline to Week 6 or end of study in mean 24-hour
                              and mean daytime (time of dose until 8:00 PM) ambulatory SBP as
                              determined by ABPM,
                         Proportion of patients with seated office cuff DBP reduced > 4
                              mmHg from baseline at Week 6 or end of study,
                         Proportion of patients who are normalized by office BP
                              measurements (defined as a trough seated SBP <135 mmHg and/or
                              DBP <85 mmHg at Week 6 or end of study), and
                         Proportion of patients with a reduction in ambulatory mean 24-hour
                              DBP > 10 mmHg from baseline at Week 6 or end of study.
Safety Measures:        Patient safety will be assessed by monitoring and reporting of adverse
                        events (AE) that occur during the study. Further safety assessments will
                        include physical examinations, 12-lead electrocardiogram (ECG), and
                        clinical laboratory tests.
Statistical Analysis:   Efficacy analyses will be conducted for two populations: Modified
                        Intent-to-Treat (ITT) and Per Protocol (PP). Descriptive statistics will be
                        presented for the observed blood pressure values, but analysis will be
                        performed on change from baseline. Change from baseline will be
                        calculated as BPt – BP0 where BPt is defined as the blood pressure
                        measurement obtained at time = t (Week 2, 4, or 6) and BP0 is the
                        baseline blood pressure (Randomization, Week 0). The primary efficacy
                        endpoint is the change from Baseline in mean seated office cuff DBP
                        (24±2 hours) at Week 6 or end of study. The primary analysis is the
                        comparison of the two treatment groups using the ITT and PP
                        populations.

                        Secondary efficacy analyses will be conducted for the ITT and PP
                        populations. In addition, analyses for change from baseline for the
                        primary efficacy endpoint will be presented in both ITT and PP
                        populations, examining the effect of race (Caucasian versus
                        Non-Caucasian), gender (male versus female), and age (< 65 years versus
                        ≥65 years) at Week 6 or end of study. These subgroup analyses by
                        demographics will be performed for the primary efficacy endpoint but not
                        for the secondary efficacy endpoints. For analyses conducted on efficacy
                        results obtained at the various scheduled visits, missing values in the ITT
                        population will be imputed using the last observation carried forward
                        (LOCF) method except for mean ambulatory SBP and DBP by ABPM.

               Continuous efficacy endpoints (e.g., change from baseline in seated and
               standing systolic and diastolic office blood pressures) will be compared
               across treatment groups using a fixed-effect two-way analysis of variance
               (ANOVA) with center and treatment as factors. Categorical response
               variables (e.g., proportion of normalized patients with SBP <135 mmHg
               and/or DBP<85 mmHg) will be compared using the
               Cochran-Mantel-Haenszel test stratified by center.

4.1 Study Endpoints

4.1.1 Efficacy Endpoints
<see the protocol synopsis>

4.1.2 Safety Endpoints
<see the protocol synopsis>



4.2 Overall Study Design

The study is a phase III, prospective, randomized, double-blind, placebo-controlled clinical trial to
evaluate the safety and effectiveness of Drug A 20 mg once daily versus placebo using 24-hour
Ambulatory Blood Pressure Monitoring (ABPM) in patients with mild to moderate hypertension.
The study includes a 3- to 4-week single-blind placebo run-in phase and a 6-week double-blind
treatment phase.
The study will receive approval from the institutional review board (IRB)/ethics committee (EC)
at each site and will be conducted in accordance with the principles outlined in the Declaration of
Helsinki. Written informed consent will be obtained from all subjects.
This study will be at 20 sites in Europe, North America and Asian Pacific.


4.3 Randomization/Blinding Procedure

A centralized, center-blocked randomization procedure will be used for treatment assignment by
means of an Interactive Voice Response System (IVRS). Subjects will be randomized 1:1 into
2 groups (Drag A n=90, placebo n=90).

Subjects and study personnel will be blinded to treatment groups (active study drug vs. placebo).


4.4 Stopping Rules

4.4.1 Subject Withdrawal
A subject (or subject's legal guardian) is free to withdraw consent and discontinue participation in
the study at any time, without prejudice to further treatment according to standard practice.

If a subject becomes pregnant, or is discovered to be pregnant, during study participation, the
Sponsor should be notified. A detailed, comprehensive medical review (for the subject and fetus)


Page 11 of 35                                                  Protocol: ABC01 Final V1.0
                                                                                        Confidential


will be conducted prior to continuing or discontinuing study participation. Pregnancy will not be
considered an SAE.
If a subject’s participation in the study is terminated early, all available data, including the
incidence of AEs and the reason for discontinuation, will be recorded on the Case Report Form
(CRF). If a serious adverse event (SAE) occurs within 30 days after the last study dose, the
investigator should follow the SAE until the event is resolved or the subject is lost to follow-up.
Resolution means the subject has returned to the baseline state of health or the condition is stable
and the Investigator does not expect any further improvement or worsening of the adverse event.
In all cases, the appropriate information will be recorded on the CRF.

4.4.2 Sponsor or Investigator Withdrawal
Any of the following are considered reason for the Investigator to remove a subject from the
study:

               The subject is uncooperative/non-compliant and will not or cannot adhere to study
                responsibilities, including all eligible study visits
               The subject was erroneously enrolled in the study
               The subject suffers an intolerable AE
               The sponsor terminates the study.

A subject's participation in the study may be discontinued at any time at the discretion of the
Investigator.

If the Sponsor, an Investigator, or a regulatory agency discovers a condition during the study to
indicate that the study or site should be terminated, this action may be taken after appropriate
consultation between the Sponsor and the Investigator. Conditions that might warrant
termination of the study include, but are not limited to the following criteria.

               The discovery of an unexpected, serious, or unacceptable risk to a subject enrolled in
                the study
               The decision on the part of the Sponsor to suspend or discontinue testing, evaluation,
                or development of the study drug
               Failure of the Investigator to comply with pertinent regulatory authority regulations
               Submission of knowingly false information from the research facility to the Sponsor,
                or other regulatory authority
               Insufficient adherence to protocol requirements


4.5 Maintenance of Randomization Codes and Procedure for Breaking Codes

Unblinding of treatment assignment during the study is discouraged and should occur only if it is
absolutely necessary to identify treatment assignment in an emergency situation due to an adverse
event (AE). If the Investigator deems identification of the study medication as necessary for the
purpose of providing urgent subject care, unblinding should proceed and the Sponsor’s Chief
Medical Officer and/or PI should be notified. Every effort should be made to contact the

Page 12 of 35                                                           Protocol: ABC01 Final V1.0
                                                                                      Confidential


Sponsor’s Chief Medical Officer and/or PI prior to unblinding. If this is not possible, then the
Investigator can proceed with determining the study medication assignment by using the
Interactive Voice Response System and monitor as soon as possible.

Note: Causality should be assessed by the Investigator prior to unblinding of treatment assignment
but must not delay treatment in an emergency situation.

The date and reason for the unblinding must be recorded in the subject’s medical record and on
the subject’s CRF.

9.1 Adverse Event and AE reporting

9.1.1 Definition of Adverse Event
Per the International Conference of Harmonisation (ICH), an AE is any unfavorable and
unintended medical occurance/sign (including an abnormal laboratory finding), symptom or
disease in a patient or clinical investigation subject administrated a pharmaceutical product and
which dose not necessarily have a causal relationship with this treatment. Pre-existing conditions
which worsen during a study are to be reported as AE, too.

9.1.2 Definition of Serious Adverse Event
A serious adverse event is any experience that suggests a significant hazard, contraindication, side
effect or precaution. It is any adverse event that at any dose fulfils at least one of the following
criteria:
• is fatal; (results in death; NOTE: death is an outcome, not an event)
• is Life-Threatening (NOTE: the term "Life-Threatening" refers to an event in which the subject
was at immediate risk of death at the time of the event; it does not refer to an event which could
hypothetically have caused a death had it been more severe).
• requires in-patient hospitalisation or prolongation of existing hospitalisation;
• results in persistent or significant disability/incapacity;
• is a congenital anomaly/birth defect;
• is medically significant or requires intervention to prevent one or other of the outcomes listed
above

9.1.3 AE Reporting and Follow-up
Non-serious adverse event occurs after the first study dose and during the study should be
recorded in CRFs and followed up until the end of the study.
Serious adverse event occurs after the informed consent is signed and up to 30 days after the last
study dose should be recorded in CRFs and followed during the study and up to 3 months after the
last study dose.

10.0 Statistical Consideration and Analysis


10.1 General Statistical Method

<see the protocol synopsis>


10.2 Analysis Population

The following three analysis populations will be utilized:

Safety: The safety analysis population will include all subjects who were randomized, and
received at least one dose of study drug.

Modified Intent-to-treat (MITT): The MITT population will include all subjects who were
randomized, received at least one dose of study drug, and who have Baseline and at least one
post-baseline measurement for seated blood pressure.

Per Protocol (PP): The per protocol population will include all subjects in the MITT population
who meet the study treatment compliance criteria and had no major protocol violations. This
population will be determined before breaking the blind.


10.3 Subject Disposition

Subject enrollment and disposition will be summarized for each treatment group and for the total
using all randomized subjects. The table will present the number and percentage of subjects who
were randomized, took study drug, completed the Treatment Period, and withdrew from the study.
The number and percentage of subjects who prematurely discontinued will also be summarized by
reasons for discontinuation.

For each population (Safety, MITT, and PP), the number and percentage of subjects included will
be reported by treatment group and total.

Enrollment and disposition, prematurely discontinued subjects, and subjects excluded from each
of the MITT and PP populations will be presented by treatment and subject in separate listings
using all randomized subjects.


10.4 Demographic and Baseline Characteristics

Demographics and Baseline characteristics will be summarized descriptively using the Safety,
MITT, and PP populations. An ANOVA with factor treatment will be performed for continuous
variables. A chi-square test will be used for the categorical variables.

The percentage of subjects with medical histories will be tabulated by treatment group and body
system. Results of physical examination, ECG, at Screening will be summarized by treatment
group.


10.5 Protocol Deviation

Protocol deviations will be identified and documented based on a review of selected data listings
prior to treatment unblinding. Protocol deviations will be presented in a data listing and tabulated
by treatment for all randomized subjects.

APPENDIX B Blood Pressure Measurement: Office and Ambulatory Blood

Pressure Monitoring


Office BP Measurement Using the Sphygmomanometer: The non-dominant arm should be used
throughout the study to obtain blood pressure measurements that will be recorded in the source document
and the Case Report Form.

Blood pressure measurements should be performed using the following criteria:
• Inflate the cuff to a pressure approximately 30 mmHg greater than systolic, as estimated from the
disappearance of the pulse in the brachial artery by palpation.
• Place the stethoscope lightly over the brachial artery.
• Measure the blood pressure with the patient's arm supported at the level of the heart.
• Deflate the cuff slowly at a rate of 2 mmHg per heartbeat.
• The first appearance of sound (phase 1) is used to define systolic blood pressure. The disappearance of
sound (phase 5) is used to define diastolic blood pressure.

It is important to avoid miscuffing – the bladder width should be at least 40% of the arm circumference
and the bladder length should be a least 80% of the arm circumference. In patients with large upper arms, a
longer and wider cuff should be used (15 cm wide cuff should be adequate). Only study personnel properly
trained in the procedures required for this protocol should perform these blood pressure measurements.
Training documentation will be maintained at the investigative site to record this specialized training.
Sitting and standing blood pressure will be measured using an appropriately calibrated
sphygmomanometer. After sitting for five minutes, three blood pressures and one heart rate measurement
should be obtained and recorded at two-minute intervals. Then after standing for one minute, one blood
pressure should be measured and recorded. If the 3 consecutive seated diastolic BP readings are not within
5 mmHg of each other, then 2 additional seated BP readings should be obtained and incorporated into the
calculated mean pressures.

Ambulatory Blood Pressure Monitoring (ABPM)

Best Corelab Services will provide the ambulatory blood pressure recording device that has been validated
independently by the American Association for the Advancement of Medical Instrumentation. The device
is an automatic, portable monitor that will be used at all centers to record BP and heart rate over a 24-hour
period on 2 occasions (Baseline and Week 6 visit or Early Termination).

The ABPM studies should be performed under similar circumstances (i.e., a working weekday). If possible,
the device should be applied on the same day of the week and as close to the same time of day as feasible
on each occasion. For each evaluation, the patient should report to the clinic 24±2 hours after the previous
morning’s dose of study medication for ABPM placement. An experienced technician should test the
device for agreement with an appropriately calibrated sphygmomanometer using a t-tube and stethoscope.
The average of 3 simultaneous ABPM and sphygmomanometer diastolic BP measurements should agree
within 7 mmHg.

The ABPM start time should precede the day’s study drug ingestion. Thus, the ABPM recorder will be
manually initiated to indicate the beginning of the test and the start time will be recorded in the CRF and
source document. The patient time of the morning dose of study medication will also be recorded in the
CRF and source document. The device will be set to obtain readings every 15 minutes during the interval
of 0600h to 2200h (to coincide with the daytime, awake period) and every 20 minutes during the interval
of 2200h to 0600h (to coincide with the night time, sleeping period). The patient will be instructed to
return to the clinic 24 hours after the post-dosing ABPM start time.


Page 34 of 35                                                  Protocol: ABC01 Final V1.0
                                                                                      Confidential


The patient should engage in their usual physical activity levels, but should avoid strenuous exercise
during the monitoring period. Additionally, sleeping during the daytime (e.g., a siesta) should be avoided
during the ABPM study period. During the actual BP measurements, the patient should be instructed to
hold their arm still and remain in place once cuff inflation begins. Data will be edited according to the
dedicated software program of the device. In addition, software will identify readings that are outside of
editing criteria and exclude them from the statistical analyses; however, these readings will remain as part
of the raw data report.

An ABPM recording will be considered adequate if:
1. The “Beginning of Test” time is 24±2 hours after the previous morning’s dose of study medication
2. The monitoring period is at least 24 hours in duration.
3. At least 70 valid readings were obtained (80% acceptance rate).
4. No more than 2 non-consecutive hours are missing a valid reading.

If the recording does not meet these minimal quality control criteria, the ABPM recordings should be
repeated once within 3 days. Patients will be instructed on the administration of the appropriate study
medications if a repeat ABPM is required. In the event the recording does meet the minimal quality control
criteria, however, the patient fails to meet the minimum inclusion BP criteria (M24DBP > 85 mmHg), the
ABPM should not be repeated and the patient should be dropped from the trial at this time (screen failure).
Patient must meet both the minimal QC criteria AND the M24DBP inclusion criteria for randomization.
