Introduction
1.1
Background
LJN452 is a highly potent agonist of the bile acid receptor Farnesoid X Receptor (FXR), 
which is expressed in liver, intestine and kidney. In the liver, FXR agonism increases 
expression of genes involved in canalicular and basolateral bile acid efflux and bile acid 
detoxifying enzymes while inhibiting basolateral bile acid uptake by hepatocytes and 
inhibiting bile acid synthesis (Calkin and Tontonoz 2012). FXR activation represses bile acid 
synthesis in the liver through induction of Small Heterodimer Partner (SHP), which is a 
negative regulator of Cyp7a1, the rate-limiting enzyme of the neutral bile acid biosynthetic 
pathway (Goodwin et al 2000). Furthermore, FXR agonists increase excretion of bile acids 
through the kidney, increase bile acid binding proteins in the ileum and stimulate 
FGF15/FGF19 expression (a key regulator of bile acid metabolism). Thus, FXR acts as a 
sensor of elevated bile acids and initiates homeostatic responses to control bile acid levels, a 
feedback mechanism that is believed to be impaired in bile acid malabsorption
(Pattni et al 2012, Walters 2014).

Figure 1-1
Co-ordinated effects of FXR on metabolism
FXR regulates bile acid metabolism through multiple mechanisms in the liver and intestine. 
Theprocesses regulated by FXR are shown in rectangular boxes. Genes are shown with up or down 
arrows to indicate the direction of regulation by FXR agonists. Arrows are used to show the flow of bile 
acids in the enterohepatic circulation or the movement of FGF15 (rodents) or FGF19 (human) from the 
enterocyte to the hepatocyte. In normal physiology, FXR detects increased levels of bileacids and 
responds by decreasing bile acid synthesis and bile acid uptake while increasing bile acid modification 
and secretion in the liver. In the intestine, FXR detects increased bile acid levels and decreases bile 
acid absorption and increases secretion of FGF15 or FGF19. The net result is a decrease in the 
overall levels of bile acids.Adaptedfrom Calkin andTontonoz 2012.

Investigational plan
3.1
Study design
This is a multi-center, double blind (patient and investigator blind, sponsor open label), 
randomized placebo controlled, crossover study to assess safety,tolerability and efficacy of 
LJN452 in patients with primary bile acid diarrhea (pBAD).In this study approximately 
30patients will be enrolled to have 24 completers.
This is a non-confirmatory trial.
Each patient will undergo a screening period (28 days), run-in period (washing out previous 
treatment effect) (up to 14 days), 2 treatment periods (14 days each), washout period (at least 
7 up to 28 days) between the treatment periods and end of study.
Figure 3-1
Study design schematic
Patients will be assessed for eligibility to enter the study at the screening visit.
Each patient will perform following visits
Screening visit: Day -28 to -2
Corporate Confidential Information
During the screening period all patients will undergo screening assessment, which may be 
completed over multiplevisits as per the patient’sconvenience. The screening results will be 
valid for 28 days, if any patientis beyond the screening validity, the patient canbe 
re-screened. Results for all screening assessment must be available before the baseline/Day 1 
pre-dose assessment. 
If the eligibilityis confirmed patientswill be asked to discontinue their sequestrants. 
Patientswill be handed over patient diary to record their daily stool type and frequency using 
Bristol Stool Chart and use of rescue medication (loperamide intake). The patient diary is 
expected to be used by patients’throughoutthe study duration.


Novartis

Page 23
Amended Protocol Version v02 (Clean)
Protocol No. CLJN452X2202
Rescue medication will be loperamide only and patients will be instructed to take 2 mg dose 
only after passage of 4 stools of Bristol Stool Scale Type 6 (Fluffy pieces with ragged edges, a 
mushy stool) or Type 7 (Watery, no solid pieces, entirely liquid). This dose may be repeated 
only after 4 hours have elapsed or passage of 4 further stools of Type 6 or 7 
(whichever occurs first). A total of no more than 16mg of loperamide may be taken in a 
24 hour period. No BA sequestrants should be used by the patients during this study.
Run-in period (Day -7 to -1 or Day -14 to -1)
Patients who have not used bile acid sequestrants for pBAD in the previous week at the time 
of screening will be evaluated for inclusion/exclusion criteria during the screening visit, and if 
found eligible will enter a 1 week run in period (Day -7 to -1) prior to the double blind 
randomized treatment phase.
Eligible patients who are treated with bile acid sequestrants (at least one dose during the 
previous two weeks) will be asked to stop their medication and enter the 2 weeks run -in 
period (Day -14 to -1) of the study. Patients will be allowed to take rescue medication 
(loperamide), which will be recorded as concomitant medication.
Patients will continue to use patient diary to record stool type and frequency along with use of 
rescue medication.
Results for all screening assessment must be available before the baseline/Day 1 pre-dose 
assessment. Screening and run-in visits may be combined for logistic reasons.
After the run-in period, patients will enter the double blind randomized treatment phase.
There will not be a separate baseline visit, but pre-dose assessment on Day 1 will be 
considered as baseline assessment.
Treatment Periods (Day 1-14):
On Day 1, patient will handover stool sample collected before dosing as pre-dose stool sample. 
Pre-dose PK, PD and biomarker samples will be collected before dosing.
In treatment period 1 on Day 1 patients will receive either 60 μg LJN452 or placebo orally 
once daily for 14 days in a 1:1 ratio. Pharmacokinetic (PK), pharmacodynamic (PD) and 
safety samples will be collected on Day 1 for up to 8 hours post dose and on Day 2 pre -dose, 
which corresponds to 24 h after Day 1 dosing. Some PK and PD sample time points on Day 1 
and Day 2 can be optional, see Assessment Schedule.
Patients will be handed over trial medication, to be administered at home enough to cover 
dosing for 14 days in each period. Throughout the 14 days of the treatment period, patients 
will be directed to take study drug at home with water in the morning in a fasting state, 
2 hours prior to the first meal of the day, preferably at the same time of the day.
Following dosing, patients will return to clinic for PK, PD, BM and safety assessment at 
various time points as described in the Assessment Schedule.
The patients will return to the clinic for a series of PK, PD and biomarker sample collections 
on Day 12.

After 2 weeks of treatment with LJN452 or placebo, patients will undergo a washout of at 
least 7 days, up to a maximum of 28 days. At the end of washout period, patients will return to 
the study site for period 2 of the study. Period 2 will be identical to period 1 except that the 
treatments will be crossed over.
Patient diary will be used to capture stool frequency, consistency and rescue medication. 
Intake of loperamide will be allowed, but will be recorded in the concomitant medication 
section of the CRF.
Study Completion visit:
The patients will return to the site 7 days’±2 days after the last dose to undergo the study 
completion evaluations. Following completion of all assessments, the patients will be 
discharged from the study. If for any reason the patientis withdrawn from the study, the 
patientwill return to the site 7 days after the last dose to undergo the study completion 
evaluations. Following completion of all assessments, the subject will be discharged from the 
study. Safety assessments will include physical examinations, ECGs, vital signs, standard

Rationale of study design
Corporate Confidential Information
This randomized, multi-center, double blind (patient and investigator blind, sponsor open 
label), placebo-controlled, cross-over study is designed to assess safety, tolerability and 
efficacy of LJN452 at 60 μg relative to placebo in patients with pBAD, as assessed by a 
reduction in stool frequency and stool type score after 2 weeks of double-blind treatment.
A cross-over design reduces variability as the treatment comparison can be done within 
patient.
Randomization will be maintained at 1:1 ratio over the entire study in order to avoid any 
sequence bias.
Multiple sites will be used to enroll patient in this study due to the underlying prevalence of 
diagnosedpBAD. It is know that differences in criteria exist in the diagnosis of pBAD in 
different regions.
In order to maintain the scientific integrity of the study, investigators and patients will remain 
blinded regarding the allocation of active or placebo. The clinical trial team will be unblinded 
throughout the dosing phase to allow analysis of safety and PK/PDdata.

3.4
Rationale for choice of comparator
There is no FXR agonist approved drug for treatment of bile acid diarrhea, thus placebo will 
be used as a comparator in this study.
3.6
Risks and benefits
Corporate Confidential Information
No more than a transient direct benefit of LJN452 treatment to patients with pBAD is 
anticipated in the short term study.
A maximum of 438 mL of blood is planned to be collected over a period of 8 weeks from 
each patient as part of the study. Additional samples needed for monitoring of any safety 
findings would be in addition to this. This is not considered to be a risk for this population.

Protocol No. CLJN452X2202
There may be unknown risks of LJN452 which may be serious and unforeseen.
The overall risk to patients with pBAD in this study is expected to be low and will be 
minimized by adherence to the inclusion/exclusion criteria, avoidance of prohibited 
concomitant medications, close clinical monitoring including on-line PK assessments, safety 
reviews and study stopping rules.
The overall risk/benefit assessment of LJN452 is supportive of the conduct of this study in 
patients with pBAD.

Study treatment
Corporate Confidential Information
Details on the storage and management of study medication, randomization and instructions 
for prescribing and taking study treatment are outlined in Section 3 of the Site Operations 
Manual.


Novartis

Amended Protocol Version v02 (Clean)
Protocol No. CLJN452X2202
6.1.1
Investigational treatment
The investigational drug, LJN452 10 µg (0.01 mg), and matching placebo will be prepared
and supplied by Novartis as single blinded packs to be dispensed by the unblinded pharmacist 
at the investigator site according to the randomization schedule.
6.2
Treatment arms
Patients will be assigned to the 2 treatment sequence (Drug/Placebo or Placebo/Drug) in a 
ratio of 1:1. The number of patients enrolled may change based on data from interim analyses.
Study treatments are defined as:

A: Single oral dose of LJN452 60 μg daily for 14 days (administered as LJN452 6 x 10 μg 
capsules).

B: Single oral dose of placebo to LJN452 0 μg daily for 14 days (administered as placebo 
to LJN452 6 x 0 μg capsules).
6.3
Permitted dose adjustments and interruptions of study treatment
Study drug dose adjustments by the investigator and/or interruptions other than for safety 
reasons are not permitted.
In case of notable adverse events, safety concerns and/or based on pharmacokinetic data 
review during the study, the following changes to the administered dose may be considered by 
the sponsor in consultation with the investigator:

Administration of a dose below the starting dose.

Administration of a dose higher than the starting dose not exceeding the exposure cap.
These changes must be recorded on the Dosage Administration Record CRF.
6.4
Treatment assignment
Randomization numbers will be assigned in ascending, sequential order to eligible patients 
(see Site Operations Manual for details). The investigator will enter the randomization 
number on the CRF.
The randomization numbers will be generated using the following procedure to ensure that 
treatment assignment is unbiased and concealed from patients and investigator staff. A 
randomization list will be produced by or under the responsibility of Novartis Drug Supply 
Management using a validated system that automates the random assignment of treatment 
arms to randomization numbers in the specified ratio. The randomization scheme for patients 
will be reviewed and approved by a member of the Novartis IIS Randomization Group.
6.5
Treatment blinding
This is a double blind study: Patients, investigator staff, and persons performing the 
assessments will remain blinded to the identity of study treatments according to the 
specifications provided in the Site Operations Manual.
The identity of the treatments will be concealed by the use of study drugs that are all identical 
in packaging, labeling, schedule of administration, appearance, and odor.


Novartis
Confidential
Page 31
Amended Protocol Version v02 (Clean)
Protocol No. CLJN452X2202
Randomization data are kept strictly confidential until the time of unblinding, and will not be 
accessible by anyone else involved in the study with the following exceptions: 
Unblinded pharmacist or authorized designee at site, and the sponsor clinical trial team.
The Interim Analysis Team may communicate interim analysis results (e.g. information 
needed for planning/modifying another study) to relevant Novartis teams for information, 
consulting and/or decision purposes.
The sponsor clinical trial team will remain unblinded throughout the study.
Unblinding to the investigator and patient will only occur in the case of patient emergencies 
(see Section 6.6) and at the conclusion of the study or after IAs.
6.6
Emergency breaking of assigned treatment code
Emergency unblinding should only be undertaken when it is essential to treat the patient 
safely and efficaciously. Most often, study treatment discontinuation and knowledge of the 
possible treatment assignments are sufficient to treat a study patient who presents with an 
emergency condition. A complete set of emergency code break cards will be provided to the 
investigator site(s) and a complete set will be available at Novartis. All code break cards must 
be retained until the end of the study and returned to Novartis. They must be stored in a secure 
place but be accessible in case of emergency. The investigator will receive a blinded code 
break card for each patient, with the details of drug treatment covered by a removable, 
scratch-off cover. In an emergency, the scratch-off cover can be removed to determine the 
treatment. The scratch-off covers are not to be removed for any reason other than an 
emergency. When the investigator removes the scratch-off cover he/she must note the date, 
time, and reason for removing it and retain this information with the case report form 
documentation. The unblinded treatment code should not be recorded on the CRF.
The investigator must also immediately inform the Novartis local monitor that the code has 
been broken.
6.7
Treatment exposure and compliance
Pharmacokinetic parameters (measures of treatment exposure) will be determined in all 
patients treated with LJN452, as detailed in Section 8.5.
6.8
Recommended treatment of adverse events
Expression of ALP is induced by FXR activation. Hence LJN452 is expected to increase 
circulating levels of ALP in a dose dependent manner and this will not necessarily indicate 
liver injury. Elevation of ALP should be interpreted in light of other tests, such as ALT, AST, 
and total bilirubin levels. Please see specific stopping rules and response to abnormal lever 
enzyme tests.
Medication used to treat adverse events must be recorded on the Concomitant 
medications/Significant non-drug therapies CRF.

6.9
Rescue medication
Use of rescue medication (loperamide) will be allowed and must be recorded on the patient 
diary/Concomitant medications/Significant non-drug therapies CRF after start of study drug.
Rescue medication will be loperamide only and patients will be instructed to take 2 mg dose 
only after passage of 3 stools of Bristol Stool Scale Type 6 (fluffy pieces with ragged edges, a 
mushy stool) or Type 7 (watery, no solid pieces, entirely liquid). This dose may be repeated 
only after 4 hours have elapsed or passage of 4 further stools of Type 6 or 7 
(whichever occurs first). A total of no more than 16 mg of loperamide may be taken in a 
24 hour period. No BA sequestrants should be used by the patients during this study.
6.10
Concomitant treatment
All prescription medications, over-the-counter drugs and significant non-drug therapies 
(including physical therapy and blood transfusions) administered or taken within the 
timeframe defined in the entry criteria prior to the start of the study and during the study, must 
be recorded on the Concomitant medications/ Significant non-drug therapies section of the CRF.
Medication entries should be specific to trade name, the single dose and unit, the frequency 
and route of administration, the start and discontinuation date and the reason for therapy.
7
Discontinuation and study completion
7.1
Discontinuation of study treatment
Patients may voluntarily discontinue study treatment for any reason at any time.
Discontinuation of study treatment will be at the discretion of the Investigator, under the 
following circumstances:

Any protocol deviation that results in a significant risk to the patient’s safety.

If continuation in the study is deemed detrimental to the patient’s well-being.
The appropriate personnel from the site and Novartis will assess whether study treatment 
should be discontinued for any patient whose treatment code has been broken inadvertently 
for any reason.
Individual patient withdrawal
Patients may voluntarily discontinue study treatment for any reason at any time.
Study treatment must be discontinued and the patient withdrawn from the study if the patient 
withdraws consent.
The study treatment must be discontinued and the patient’s withdrawal from the study should 
be at the investigator’s discretion if the following occur:

Pregnancy.

Intolerable or clinically significant diarrhea.

Hypersensitivity reaction to LJN452.


Novartis
Confidential
Page 33
Amended Protocol Version v02 (Clean)
Protocol No. CLJN452X2202

An increase in aminotransferase enzymes (ALT or AST) of greater than 3 x ULN AND 
EITHER symptoms such as anorexia, fatigue, right upper quadrant abdominal pain or 
tenderness, fever, rash and/or eosinophilia OR elevation of serum TBL to greater than 
2 x ULN OR INR>1.5.

Medically significant (>8 x ULN) ALT or AST elevation.

An AE with a CTCAE rating of Grade 3 or higher regardless of drug causality, unless it is 
caused by elevation of ALT (as above) or an accident that could not reasonably be 
attributable to the drug.

An AE with a CTCAE rating of Grade 2 or higher considered to be due to study drug, 
unless it is caused by elevation of ALT (as above).

An elevation of ALP or GGT of >2.5 x ULN considered to be due to study drug or >5 × ULN 
regardless of drug causality.
Patients who discontinue study treatment or who decide they do not wish to participate in the 
study further should NOT be considered withdrawn from the study UNLESS they withdraw 
their consent (see Section 7.3). Where possible, they should return for follow up assessments. 
If they fail to return for assessments for unknown reasons, every effort (e.g. telephone, e-mail, 
letter) should be made to contact them as specified in Section 7.2.1.
7.2
Study completion and post-study treatment
Each patient will be required to complete the study in its entirety and thereafter no further 
study treatment will be made available to them. Study completion is defined as when the last 
patient completes their End of Study visit, and any repeat assessments associated with this 
visit have been documented and followed-up appropriately by the Investigator, or in the event 
of an early study termination decision, the date of that decision.
At a minimum, patients will be contacted for safety evaluations during the 30 days following 
the Study Completion visit, including a final post-study safety contact at the 30-day point. 
Documentation of attempts to contact the patient should be recorded in the source 
documentation.
The investigator must provide follow-up medical care for all patients who are prematurely 
withdrawn from the study, or must refer them for appropriate ongoing care. All patients who 
complete the study will return to their standard of care after the end of study visit.
7.2.1
Lost to follow-up
For patients whose status is unclear because they fail to appear for study visits without stating 
an intention to discontinue or withdraw, the investigator should show "due diligence" by 
documenting in the source documents steps taken to contact the patient, e.g. dates of 
telephone calls, registered letters, etc. A patient should not be formally considered lost to 
follow-up until his/her scheduled end of study visit would have occurred.
7.3
Withdrawal of consent
Patients may voluntarily withdraw consent to participate in the study for any reason at any 
time.


Novartis
Confidential
Page 34
Amended Protocol Version v02 (Clean)
Protocol No. CLJN452X2202
Withdrawal of consent occurs only when a patient does not want to participate in the study 
anymore and does not want any further visits or assessments and does not want any further 
study related contact and does not allow analysis of already obtained biologic material.
If a patient withdraws consent, the investigator must make every effort to determine the 
primary reason for this decision and record this information. Study treatment must be 
discontinued and no further assessments conducted. All biological material that has not been 
analyzed at the time of withdrawal must not be used. Further attempts to contact the patient 
are not allowed unless safety findings require communicating or follow-up.
7.4
Study Stopping rules
The study will be placed on hold and may be stopped or amended based on full review of all 
available clinical safety data and discussion with the Investigator if any of the following occur:

Two or more patients on study drug experience a similar adverse event that is a CTCAE 
Grade 3 or higher apart from ALT elevation (see below).

One patient on study drug experiences any adverse event that is CTCAE Grade 4 or higher 
apart from ALT elevation (see below) other than an accident that is not related to study 
drug).

Two or more patients with an increase in aminotransferase enzymes (ALT or AST) of 
greater than 3 x ULN AND EITHER symptoms such as anorexia, fatigue, right upper 
quadrant abdominal pain or tenderness, fever, rash and/or eosinophilia OR elevation of 
serum total bilirubin to greater than 2 x ULN OR INR >1.5.

Two or more patients on study drug experience an elevation of ALP or GGT of >5 × ULN 
or one patient on study drug experiences an elevation of ALP or GGT of >20 × ULN. 

The Principal Investigator and the Sponsor consider that the number and/or severity of 
adverse events justify discontinuation of the study.

The Sponsor unilaterally requests discontinuation of the study.
Safety reviews will be conducted jointly between medically qualified representatives of the 
Sponsor and Investigator and a joint decision will be made. The severity of adverse events 
will be graded by the study site Investigator (or his designee) based on clinical judgment and 
captured in the CRF AE page. This information will be used to quantify events that may lead 
to patient’s discontinuation or stopping of the study.
Patients may voluntarily withdraw from the study for any reason at any time. They may be 
considered withdrawn if they state an intention to withdraw, fail to return for visits, or become 
lost to follow-up for any other reason. If a patient withdrawal occurs for any reason, the 
Investigator must make every effort to determine the primary reason for a patient’s 
withdrawal from the study and record this information on the Study Completion CRF.

7.5
Early study termination
The study can be terminated at any time for any reason by Novartis. Should this be necessary, 
patients should be seen as soon as possible and treated as a prematurely withdrawn patient. 
The investigator may be informed of additional procedures to be followed in order to ensure 
that adequate consideration is given to the protection of the patient’s interests.
The investigator will be responsible for informing IRBs/IECs of the early termination of the 
trial.

8.1
Informed consent procedures
Eligible patients may only be included in the study after providing written (witnessed, where 
required by law or regulation), IRB/IEC-approved informed consent.
Informed consent must be obtained before conducting any study-specific procedures (i.e. all 
of the procedures described in the protocol). The process of obtaining informed consent 
should be documented in the patientsource documents.
The date of signing of informed consent (and withdrawal, if later withdrawn) should be 
documented in the CRF.
Novartis will provide to investigators a proposed informed consent form that complies with 
the ICH GCP guideline and regulatory requirements and is considered appropriate for this 
study. Any changes to the proposed consent form suggested by the investigator must be 
agreed to by Novartis before submission to the IRB/IEC.
Pregnancy outcomes must be collected for the female partnersof any males who took study 
treatment in this study. Consent to report information regarding these pregnancy outcomes 
should be obtained from the mother.
In the event that Novartis wants to perform testing on the samples that are not described in 
this protocol, additional Institutional Review Board and/or Ethics Committee approval will be 
obtained.
The study includes an optional scintigraphic clonic transit assessment in a US center only 
which requires a separate signature if the patient agrees to participate. As part of this protocol 
only Investigators in US will present this option to the patient. The process of obtaining 
consent should be exactly the same as described above for the main informed consent.
A copy of the approved version of all consent forms must be provided to the Novartis monitor 
after IRB/IEC approval.
8.2
Patient demographics/other baseline characteristics
Corporate Confidential Information
Patient demographic and baseline characteristic data will be collected on all patients.

Patient-Reported Outcome - IBS-QOL
The IBS-QOL is a self-reported quality-of-life measure specific to Irritable Bowel Syndrome 
(IBS) that can be used to assess the impact of IBS and its treatment. The IBS-QOL was 
developed using a needs based model. The IBS-QOL consists of 34 items, each with a 
five-point response scale.
The individual responses to the 34 items are summed and averaged for a total score and then 
transformed to a 0-100 scale for ease of interpretation with higher scores indicating better IBS 
specific quality of life. There are also eight subscale scores for the IBS-QOL 
(Dysphoria, Interference with Activity, Body Image, Health Worry, Food Avoidance, 
Social Reaction, Sexual, Relationships).
The IBS-QOL is designed to be self-administered, and takes an average of 10 minutes to 
complete. The IBS-QOL can be interviewer-administered if necessary.
The transformation formula used for the IBS-QOL total and scale scores is:
Score = (The sum of the items - lowest possible score/Possible raw score range)*100

Safety monitoring
9.1
Adverse events
An adverse event (AE) is any untoward medical occurrence (i.e., any unfavorable and 
unintended sign [including abnormal laboratory findings], symptom or disease) in a patient or 
clinical investigation patient after providing written informed consent for participation in the 
study. Therefore, an AE may or may not be temporally or causally associated with the use of a 
medicinal (investigational) product.
The occurrence of adverse events should be sought by non-directive questioning of the patient 
at each visit during the study. Adverse events also may be detected when they are volunteered 
by the patient during or between visits or through physical examination, laboratory test, or 
other assessments.
Abnormal laboratory values or test results constitute adverse events only if they fulfill at least 
one of the following criteria:

they induce clinical signs or symptoms,

they are considered clinically significant,

they require therapy.
Clinically significant abnormal laboratory values or test results should be identified through a 
review of values outside of normal ranges/clinically notable ranges, significant changes from 
baseline or the previous visit, or values which are considered to be non-typical in patients with 
underlying disease. Investigators have the responsibility for managing the safety of individual 
patient and identifying adverse events. Alert ranges for liver related events are included in 
Section 9.3.
Adverse events must be recorded on the Adverse Events CRF for patients that pass screening 
and enter into the study. The adverse events should be reported according to the signs, 
symptoms or diagnosis associated with them, and accompanied by the following information:
1. the Common Toxicity Criteria (CTC) AE grade (version 4) - if CTC-AE grading does not 
exist for an adverse event, use:

1=mild,

2=moderate,

3=severe

4=life threatening.
CTC-AE grade 5 (death) is not used, but is collected in other CRFs (e.g. Study Completion, 
Death/Survival).
2. its relationship to the study treatment (no/yes), ,
3. its duration (start and end dates) or if the event is ongoing an outcome of not 
recovered/not resolved should be reported.
4. whether it constitutes a serious adverse event (SAE) See Section 9.2 for definition of SAE
5. action taken regarding [study] treatment(select as appropriate).


Novartis
Confidential
Page 47
Amended Protocol Version v02 (Clean)
Protocol No. CLJN452X2202
All adverse events should be treated appropriately. Treatment may include one or more of the 
following:

no action taken (i.e. further observation only)

study treatment dosage adjusted/temporarily interrupted

study treatment permanently discontinued due to this adverse event

concomitant medication given

non-drug therapy given

patient hospitalized/patient’s hospitalization prolonged
6. its outcome (not recovered/not resolved; recovered/resolved; recovering/resolving, 
recovered/resolved with sequelae; fatal; or unknown)
Once an adverse event is detected, it should be followed until its resolution or until it is 
judged to be permanent, and assessment should be made at each visit (or more frequently, if 
necessary) of any changes in severity, the suspected relationship to the study drug, the 
interventions required to treat it, and the outcome.
Information about common side effects already known about the investigational drug can be 
found in the Investigator Brochure (IB) or Core Data Sheet (for marketed drugs) or will be 
communicated between IB updates in the form of Investigator Notifications. This information 
will be included in the patient informed consent and should be discussed with the patient 
during the study as needed.
The investigator should also instruct each patient to report any new adverse event (beyond the 
protocol observation period) that the patient, or the patient’s personal physician, believes 
might reasonably be related to study treatment. This information should be recorded in the 
investigator’s source documents; however, if the AE meets the criteria of an SAE, it must be 
reported to Novartis.
9.2
Serious adverse event reporting
9.2.1
Definition of SAE
An SAE is defined as any adverse event (appearance of (or worsening of any pre-existing) 
undesirable sign(s), symptom(s) or medical conditions(s) which meets any one of the 
following criteria:

is fatal or life-threatening

results in persistent or significant disability/incapacity

constitutes a congenital anomaly/birth defect

requires inpatient hospitalization or prolongation of existing hospitalization, unless 
hospitalization is for: 

routine treatment or monitoring of the studied indication, not associated with any 
deterioration in bile acid malabsorption diarrhea

elective or pre-planned treatment for a pre-existing condition that is unrelated to the 
indication under study and has not worsened since the start of study drug


Novartis
Confidential
Page 48
Amended Protocol Version v02 (Clean)
Protocol No. CLJN452X2202

treatment on an emergency outpatient basis for an event not fulfilling any of the 
definitions of a SAE given above and not resulting in hospital admission

social reasons and respite care in the absence of any deterioration in the patient’s 
general condition

is medically significant, i.e. defined as an event that jeopardizes the patient or may require 
medical or surgical intervention.
Life-threatening in the context of a SAE refers to a reaction in which the patient was at risk of 
death at the time of the reaction; it does not refer to a reaction that hypothetically might have 
caused death if more severe.
All malignant neoplasms will be assessed as serious under “medically significant” if other 
seriousness criteria are not met.
Any suspected transmission via a medicinal product of an infectious agent is also considered a 
serious adverse reaction.
Medical and scientific judgment should be exercised in deciding whether other situations 
should be considered serious reactions, such as important medical events that might not be 
immediately life threatening or result in death or hospitalization but might jeopardize the 
patient or might require intervention to prevent one of the other outcomes listed above. 
Examples of such events are 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 dependency or abuse.
All AEs (serious and non-serious) are captured on the CRF, SAEs also require individual 
reporting to DS&E as per Section 9.2.2.
9.2.2
SAE reporting
To ensure patient safety, every SAE, regardless of causality, occurring after the patient has 
provided informed consent and until 30 days following the last administration of study 
treatment must be reported to Novartis within 24 hours of learning of its occurrence as 
described below. Any SAEs experienced after this should only be reported to Novartis if the 
investigator suspects a causal relationship to study treatment.
Recurrent episodes, complications, or progression of the initial SAE must be reported as 
follow-up to the original episode, regardless of when the event occurs. This report must be 
submitted within 24 hours of the investigator receiving the follow-up information. An SAE 
that is considered completely unrelated to a previously reported one should be reported 
separately as a new event.
Information about all SAEs (either initial or follow up information) is collected and recorded 
on the paper Serious Adverse Event Report Form. The investigator must assess the 
relationship to each specific component of study treatment (if study treatment consists of 
several drugs) complete the SAE Report Form in English, and send the completed, signed 
form by fax within 24 hours after awareness of the SAE to the local Novartis Drug Safety and 
Epidemiology Department, notifying the Clinical Trial Leader. Contact information is listed 
in the Site Operations Manual.


Novartis
Confidential
Page 49
Amended Protocol Version v02 (Clean)
Protocol No. CLJN452X2202
The original copy of the SAE Report Form and the fax confirmation sheet must be kept with 
the source documentation at the study site. Follow-up information should be provided using a 
new paper SAE Report Form stating that this is a follow-up to a previously reported SAE.
SAEs (initial and follow-up) that are recorded electronically in the Electronic Data Capture 
system should be entered, saved and e-signed within 24 hours of awareness of the SAE or 
changes to an existing SAE. These data will automatically be submitted to Novartis Drug 
Safety & Epidemiology immediately after investigator signature or 24 hours after entry, 
whichever occurs first. Study site personnel must also inform the Clinical Trial Leader.
Follow- up information provided should describe whether the event has resolved or continues, 
if and how it was treated, whether the treatment code was broken or not and whether the 
patient continued or withdrew from study participation. Each re-occurrence, complication, or 
progression of the original event should be reported as a follow-up to that event regardless of 
when it occurs.
If the SAE is not previously documented in the Investigator’s Brochure or Package Insert 
(new occurrence) and is thought to be related to the investigational treatment a Drug Safety 
and Epidemiology Department associate may urgently require further information from the 
investigator for Health Authority reporting. Novartis may need to issue an Investigator 
Notification (IN) to inform all investigators involved in any study with the same 
investigational treatment that this SAE has been reported. Suspected Unexpected Serious 
Adverse Reactions (SUSARs) will be collected and reported to the competent authorities and 
relevant ethics committees in accordance with EU Guidance 2011/C 172/01 or as per national 
regulatory requirements in participating countries.
9.3
Liver safety monitoring
To ensure patient safety and enhance reliability in determining the hepatotoxic potential of an 
investigational drug, a standardized process for identification, monitoring and evaluation of 
liver events has to be followed.
The following two categories of abnormalities / adverse events have to be considered during 
the course of the study:

Liver laboratory triggers, which will require repeated assessments of the abnormal 
laboratory parameter

Liver events, which will require close observation, follow-up monitoring and completion 
of the standard base liver CRF pages
Please refer to Table 9-1 and Table 9-2 for complete definitions of liver laboratory triggers 
and liver events.
Every liver laboratory trigger or liver event should be followed up by the investigator or 
designated personal at the trial site, as summarized below and detailed in in Table 9-2.


Novartis
Confidential
Page 50
Amended Protocol Version v02 (Clean)
Protocol No. CLJN452X2202
For the liver laboratory trigger:

Repeating the LFT within the next week to confirm elevation.
These LFT repeats should be performed using the central laboratory if possible. If this is not 
possible, then the repeats can be performed at a local laboratory to monitor the safety of the 
patient. Repeats laboratory should then be performed at central laboratory as soon as possible. 
If a liver event is subsequently reported, any local LFTs previously conducted that are 
associated with this event should be reported on the Liver CRF pages.
For the liver events:

Repeating the LFT to confirm elevation as appropriate

Discontinuation of the investigational drug (refer to Section 7.1, if appropriate

Hospitalization of the patient if appropriate

A causality assessment of the liver event via exclusion of alternative causes (e.g. disease, 
co-medications)

An investigation of the liver event which needs to be followed until resolution.
These investigations can include serology tests, imaging and pathology assessments, 
hepatologist’s consultancy, based on investigator’s discretion. All follow-up information, and 
the procedures performed should be recorded as appropriate in the CRF, including the liver 
event overview CRF pages.

Pregnancy reporting
To ensure patient safety, each pregnancy in a patient on study drug must be reported to 
Novartis within 24 hours of learning of its occurrence. The pregnancy should be followed up 
to determine outcome, including spontaneous or voluntary termination, details of the birth, 
and the presence or absence of any birth defects, congenital abnormalities, or maternal and/or 
newborn complications. The study drug must be discontinued, though the patient may stay in 
the study, if she wishes to do so. All assessments that are considered as a risk during 
pregnancy must not be performed. The patient may continue all other protocol assessments. 
Pregnancy must be recorded on a Pharmacovigilance Pregnancy Form and reported by the 
investigator to the local Novartis Drug Safety and Epidemiology Department. Pregnancy 
follow-up should be recorded on the same form and should include an assessment of the 
possible relationship to the Novartis study drug of any pregnancy outcome. Any SAE 
experienced during pregnancy must be reported on an SAE Report Form.
Pregnancy outcomes must be collected for the female partners of any males who took study 
treatment in this study. Consent to report information regarding these pregnancy outcomes 
should be obtained from the mother.
9.5
Early phase safety monitoring
The Investigator will monitor adverse events in an ongoing manner and inform the Sponsor of 
any clinically relevant observations. Any required safety reviews will be made jointly 
between medically qualified personnel representing the Sponsor and Investigator. 
Such evaluations may occur verbally, but the outcome and key discussion points will be 
summarized in writing (e-mail) and made available to both Sponsor and all Investigator(s). 
Criteria pertaining to stopping the study/treatment or adapting the study design are presented 
above.
When two or more clinical site(s) are participating in the clinical study, the Sponsor will 
advise the Investigator(s) at all sites in writing (e-mail) (and by telephone if possible) of any 
new, clinically relevant safety information reported from another site during the conduct of 
the study in a timely manner.
10
Data review and database management
10.1
Site monitoring
Before study initiation, at a site initiation visit or at an investigator’s meeting, a Novartis 
representative will review the protocol and CRFs with the investigators and their staff. 
During the study Novartis employs several methods of ensuring protocol and GCP 
compliance and the quality/integrity of the sites’ data. The monitor will visit the site to check 
the completeness of patient records, the accuracy of entries on the CRFs, the adherence to the 
protocol and to Good Clinical Practice, the progress of enrollment, and to ensure that study 
drug is being stored, dispensed, and accounted for according to specifications. Key study 
personnel must be available to assist the monitor during these visits.


Novartis
Confidential
Page 54
Amended Protocol Version v02 (Clean)
Protocol No. CLJN452X2202
The investigator must maintain source documents for each patient in the study, consisting of 
case and visit notes (hospital or clinic medical records) containing demographic and medical 
information, laboratory data, electrocardiograms, and the results of any other tests or 
assessments. All information on CRFs must be traceable to these source documents in the 
patient's file. The investigator must also keep the original informed consent form signed by 
the subject (a signed copy is given to the subject).
The investigator must give the monitor access to all relevant source documents to confirm 
their consistency with the CRF entries. Novartis monitoring standards require full verification 
for the presence of informed consent, adherence to the eligibility criteria, documentation of 
SAEs, and the recording of data that will be used for all primary and safety variables. 
Additional checks of the consistency of the source data with the CRFs are performed 
according to the study-specific monitoring plan. No information in source documents about 
the identity of the patients will be disclosed.
10.2
Data collection
Designated investigator staff will enter the data required by the protocol into the Electronic 
Case Report Forms using fully validated software that conforms to 21 CFR Part 11 
requirements. Designated investigator site staff will not be given access to the EDC system 
until they have been trained. Automatic validation programs check for data discrepancies and, 
by generating appropriate error messages, allow the data to be confirmed or corrected before 
transfer of the data to the CRO working on behalf of Novartis. The Investigator must certify 
that the data entered into the Electronic Case Report Forms are complete and accurate. 
After database lock, the investigator will receive a CD-ROM or paper copies of the patient 
data for archiving at the investigational site.
Data not requiring a separate written record will be defined in the Site Operations Manual and 
assessment schedule and can be recorded directly on the CRFs. All other data captured for this 
study will have an external originating source (either written or electronic) with the CRF not 
being considered as source.
10.3
Database management and quality control
All data should be recorded, handled and stored in a way that allows its accurate reporting, 
interpretation and verification.
CRO working on behalf of Novartis review the data entered into the eCRFs by investigational 
staff for completeness and accuracy and instruct the site personnel to make any required 
corrections or additions. Queries are sent to the investigational site using an electronic data 
query. Designated investigator site staff is required to respond to the query and confirm or 
correct the data. If the electronic query system is not used, a paper Data Query Form will be 
faxed to the site. Site personnel will complete and sign the faxed copy and fax it back to CRO 
working on behalf of Novartis who will make the correction to the database.
Concomitant medications entered into the database will be coded using the WHO Drug 
Reference List, which employs the Anatomical Therapeutic Chemical classification system. 
Medical history/current medical conditions and adverse events will be coded using the 
Medical dictionary for regulatory activities (MedDRA) terminology.

Laboratory samples will be processed centrally and the results will be sent electronically to a 
designated CRO.
Diary data will be entered into an electronic diary by the patient. The system will be supplied 
by a vendor(s), who will also manage the database. The data will be sent electronically to a 
designated CRO. In case the electronic diary is not used then the patients will enter data in 
paper diary. These diaries will be handed over to site and site personnel will enter data in the 
clinical database or send them to the designated CRO to enter data in the clinical database.
At the conclusion of a non-IRT study, the occurrence of any emergency code breaks will be 
determined after return of all code break reports and unused drug supplies to Novartis.
The occurrence of any protocol deviations will be determined. After these actions have been 
completed and the database has been declared to be complete and accurate, it will be locked 
and the treatment codes will be unblinded and made available for data analysis. Any changes 
to the database after that time can only be made by joint written agreement between the 
Global Head of Clinical Information Sciences and the Clinical Franchise Head.
DNA samples:
To maximize confidentiality, all samples and the information associated with the samples will 
be double-coded to prevent the exposure of the patient’s information and identity. 
This double-coding process allows Novartis to go back and destroy the sample at the patient’s 
request.  In addition, sample information is stored in one secured database while genetic data 
is stored in an independent secured database.
The use of DNA to search for biomarkers of disease and drug action is exploratory. Any 
results from this DNA study will not be placed in the patient’s medical records.
10.4
Data Monitoring Committee
A Data Monitoring Committee (DMC) has been assembled for this compound to monitor 
safety data. This committee is comprised of Novartis personnel not directly involved with the
study and include one or more Novartis physician with expertise in the indication. The DMC will 
convene as outlined in the DMC Charter to review an event or combination of events that fulfil 
the study stopping rules defined in Section 7.4.
In addition, adverse events, including clinical laboratory data will be continuously reviewed 
by the Novartis Clinical trial team, including the study physician, on an ongoing basis as data 
become available from the Electronic Data Capture system.

Treatments (study drug, rescue medication, other concomitant 
therapies, compliance)
Data for study drug administration (rescue medication) and concomitant therapies will be 
listed by treatment sequence and patient.
11.4
Analysis of the primary variable(s)
11.4.1
Variable(s)
The primary analysis variables are: a) stool frequency, b) and stool form assessed by the 
Bristol stool chart.
11.4.2
Statistical model, hypothesis, and method of analysis
A repeated measures analysis will be done for the two-dimensional endpoint: weekly stool 
frequency and the corresponding average stool form. The analysis will include fixed effects 
for sequence (Drug/Placebo or Placebo/Drug), Treatment (Week 1 Drug, Week 2 Drug, Week 
1 Placebo or Week 2 Placebo), and period (1 or 2). The model will assume an arbitrary 2 by 2 
covariance matrix for the two-dimensional endpoint (frequency, form) and a compound 
symmetry covariance matrix for each individual endpoint. Point estimates of the weekly & 
biweekly treatment effect on stool frequency and form will be reported together with 95% 
simultaneous confidence intervals (confidence ellipsoids).
Baseline weekly stool frequency and the corresponding average stool form will be analyzed 
similarly using the method described above to assess unequal carryover effects.

Ethical considerations
12.1
Regulatory and ethical compliance
This clinical study was designed and shall be implemented and reported in accordance with 
the ICH Harmonized Tripartite Guidelines for Good Clinical Practice, with applicable local 
regulations (including European Directive 2001/20/EC, US Code of Federal Regulations Title 
21, and Japanese Ministry of Health, Labor, and Welfare), and with the ethical principles laid 
down in the Declaration of Helsinki.
12.2
Responsibilities of the investigator and IRB/IEC
Before initiating a trial, the investigator/institution should obtain approval/favorable opinion 
from the Institutional Review Board/Independent Ethics Committee (IRB/IEC) for the trial 
protocol, written informed consent form, consent form updates, patient recruitment 
procedures (e.g. advertisements) and any other written information to be provided to patients. 
Prior to study start, the investigator is required to sign a protocol signature page confirming 
his/her agreement to conduct the study in accordance with these documents and all of the 
instructions and procedures found in this protocol and to give access to all relevant data and 
records to Novartis monitors, auditors, Novartis Quality Assurance representatives, designated 
agents of Novartis, IRBs/IECs, and regulatory authorities as required. If an inspection of the 
clinical site is requested by a regulatory authority, the investigator must inform Novartis 
immediately that this request has been made.
For multi-center trials, a Coordinating Investigator will be selected by Novartis around the 
time of Last Patient Last Visit to be a reviewer and signatory for the clinical study report.
12.3
Publication of study protocol and results
Novartis assures that the key design elements of this protocol will be posted in a publicly 
accessible database such as clinicaltrials.gov. In addition, upon study completion and 
finalization of the study report the results of this trial will be either submitted for publication 
and/or posted in a publicly accessible database of clinical trial results.
13
Protocol adherence
This protocol defines the study objectives, the study procedures and the data to be collected 
on study participants. Additional assessments required to ensure safety of patients should be 
administered as deemed necessary on a case by case basis. Under no circumstances should an 
investigator collect additional data or conduct any additional procedures for any research 
related purpose involving any investigational drugs.
Investigators must apply due diligence to avoid protocol deviations. If the investigator feels a 
protocol deviation would improve the conduct of the study this must be considered a protocol 
amendment, and unless such an amendment is agreed upon by Novartis and approved by the 
IRB/IEC/REB it cannot be implemented. All significant protocol deviations will be recorded 
and reported in the CSR.

13.1
Protocol Amendments
Any change or addition to the protocol can only be made in a written protocol amendment that 
must be approved by Novartis, Health Authorities where required, and the IRB/IEC prior to 
implementation.
Only amendments that are intended to eliminate an apparent immediate hazard to patients 
may be implemented immediately, provided the Health Authorities and the reviewing 
IRB/IEC are subsequently notified by protocol amendment.
Notwithstanding the need for approval of formal protocol amendments, the investigator is 
expected to take any immediate action required for the safety of any patient included in this 
study, even if this action represents a deviation from the protocol. In such cases, the CTL 
should be informed and (serious) adverse event reporting requirements (Section 9) followed 
as appropriate.

Study design and treatment
This is a multi-center, double blind (patient and investigator blind, sponsor open label),
randomized placebo controlled, crossover study to assess safety, tolerability and efficacy of
LJN452 in patients with pBAD. In this study approximately 30 patients will be enrolled to 
have 24 completers. 
This is a non-confirmatory trial.
Figure 1-1
Study design
In treatment period 1 on Day 1 patients will receive either 60 μg LJN452 or placebo orally
once daily for 14 days in a 1:1 ratio. Pharmacokinetic (PK), pharmacodynamic (PD) and
safety samples will be collected on Day 1 for up to 8 hours post dose and on Day 2 pre-dose,
which corresponds to 24 h after Day 1 dosing.
Patients will be handed over trial medication, to be administered at home enough to cover
dosing for 14 days in each period. Throughout the 14 days of the treatment period, patients
will be directed to take study drug at home with water in the morning in a fasting state,
2 hours prior to the first meal of the day, preferably at the same time of the day.
After 2 weeks of treatment with LJN452 or placebo, patients will undergo a washout of at
least 7 days, up to a maximum of 28 days. At the end of the washout period, patients will 
return to the study site for period 2 of the study. Period 2 will be identical to period 1 except 
that the treatments will be crossed over.
The randomization will be maintained at a 1:1 ratio over the entire study in order to avoid any
sequence bias.

First interpretable results (FIR)
First interpretable results (FIR) will be provided for this trial.
The study FIR template (mock slides) can be found in CREDI in the study RAP folder.
The template shows the analysis / results to be presented in the FIR. Study outputs required to 
be created at the time of the FIR will be highlighted in TFL shells document and marked as 
“Key” in the Programming Deliverables Tracker (PDT) output list.

Statistical methods: Analysis sets
For patientsfor which the actual treatment received does not match the randomized treatment 
the treatment actually received will be used for the analysis.
For patients for which the actual sequence of treatments received does not match the 
randomized sequence of treatments, the actual sequence will be used for analysis involving a 
sequence component (e.g. ANOVAs with a sequence effect) if the actual sequence is one of 
the sequences planned in the study design. If the actual sequence is not one of the sequences 
planned in the study design, the randomized sequence will be used for analysis involving a 
sequence component but data points from periods in which the patienthas not received the 
randomized treatment will be excluded from the analysis. 
The safety analysis set will include all patients that received any study drug.
The PK analysis set will include all patients with available PK data and no protocol deviations 
with relevant impact on PK data.
The PD analysis set will include all patients with available PD data and no protocol deviations
with relevant impact on PD data.
The analysis sets and protocol deviation codes are related as follows:
