SYNOPSIS 
Study Title 
A Phase 2, randomized, placebo-controlled, multicenter study to investigate the efficacy and safety of 
GED-0507-34-Levo (GED0507) for treatment of subjects with active ulcerative colitis. 
Indication 
Active ulcerative colitis (UC). 
Objectives 
Primary Objective: 
To evaluate the clinical efficacy of GED-0507-34-Levo (80 mg twice daily [BID] and 160 mg BID), 
compared with placebo, in subjects with active UC. 
Secondary Objective: 
To evaluate the safety and tolerability of GED-0507-34-Levo (80 mg BID and 160 mg BID), 
compared with placebo, in subjects with active UC. 
Exploratory Objective: 
To evaluate the onset of clinical effect of GED-0507-34-Levo (80 mg BID and 160 mg BID), 
compared with placebo, in subjects with active UC. 
Pharmacokinetic Objective:  
 
To characterize the pharmacokinetics (PK) of GED-0507-34-Levo in subjects with active UC. 
 
To evaluate the change in biomarkers such as C-reactive protein (CRP) and fecal calprotectin 
(FCP) in response to GED-0507-34-Levo (80 mg BID and 160 mg BID), compared with 
placebo, in subjects with active UC. 
 
To explore the histological effects of GED-0507-34-Levo (80 mg BID and 160 mg BID) such as 
inflammatory cell infiltration and tissue destruction in colonic mucosal biopsies from subjects 
with active UC (Geboes Index). 
Study Design 
This is a Phase 2, multicenter, randomized, double-blind, placebo-controlled, parallel-group study to 
evaluate the efficacy and safety of 2 doses of GED-0507-34-Levo in subjects with active, mild-to-
moderate UC (defined as a Modified Mayo score [MMS] of ≥ 4 to ≤ 8, with a Stool Frequency sub-
score [SFS] ≥ 1, a Rectal Bleeding sub-score [RBS] = 1 or 2 and an endoscopic sub-score > 1 and 
< 3). 
Approximately 207 subjects will be treated with 80 mg BID, 160 mg BID, or identically appearing 
placebo BID for up to 8 weeks. Treatment will be assigned via an Interactive Web Response System 
(IWRS). 
The study will consist of 3 parts:  
 
In Part 1, 24 subjects will be randomized with 8 subjects per treatment group. The Safety 
evaluation (clinical, hematological, and biochemistry) on these 24 subjects will be assessed by 
an Independent Safety Committee.  
 
After the 24th subject is enrolled in Part 1, then Part 2 will start in which new subjects will be 
randomized only in the 80 mg BID and placebo groups in a 1:1 ratio.

Page 9 
 
Once the 24 subjects in Part 1 have completed 8 weeks of treatment and the Safety evaluation 
has been completed with no safety concerns, then Part 3 will continue to enroll subjects 
randomized into all 3 treatment groups. An unequal randomization will be used in Part 3 of the 
study in order to ensure approximately equal numbers of subjects randomized into each of the 
3 treatment groups across the 3 study parts. 
The study will consist of 3 phases: 
 
Screening Phase – up to 4 weeks 
 
Double-blind Placebo-controlled Phase – Weeks 0 to 8 
 
Follow-up Phase – Week 9 
Double-blind Placebo-controlled Phase 
Eligible subjects will enter the Double-blind Placebo-controlled Phase at the Baseline Visit 
(Week 0/Visit 2). Subjects will be randomly assigned to study treatment as described above. All 
subjects will receive high-density polyethylene (HDPE) bottles of identical appearance to maintain 
blinding. 
Subjects will continue to receive the treatment assigned at baseline for 8 weeks. 
Study Population 
The study population consists of female and male subjects 18 years and older at the time of signing 
the informed consent form (ICF). The major eligibility criteria are: 
 
Diagnosis of UC with a duration of at least 3 months prior to the Screening Visit. 
 
MMS ≥ 4 to ≤ 8 prior to randomization in the study. 
 
SFS ≥ 1 and RBS = 1 or 2. 
 
Mayo endoscopic sub-score > 1 and < 3 prior to randomization in the study. 
 
Subjects with relapsing UC who have been in relapse for > 2 weeks will be excluded. 
 
Subjects who have relapsed on maintenance therapy with doses of 5-aminosalicylic acid (5-
ASA) > 2.4 g/day will be excluded from the study. If a subject had a recent 5-ASA dose 
reduction from > 2.4 g/day to ≤ 2.4 g/day and relapsed within 2 weeks of that dose reduction, 
the subject will not be eligible.  
 
Subjects who have unsuccessfully treated their current relapse with steroids or a 5-ASA dose of 
> 2.4 g/day will be excluded from the study. 
 
Subjects with proctitis (extent of inflammation ≤ 15 cm), previous colonic surgery, Crohn’s 
disease, immediate risk of toxic megacolon, or a stool culture positive for enteric pathogens 
(including Salmonella, Shigella, Yersinia, Aeromonas, Plesiomonas, or Campylobacter) will be 
excluded as well those with Clostridium difficile toxin present or with ova or parasites as 
detected by microscopy.  
 
The use of systemic or rectal steroids within the last 4 weeks, immunosuppressants within the 
last 6 weeks, antibiotic use within the last 7 days, or repeated use of any anti-inflammatory 
drugs within 7 days prior to the Baseline Visit will exclude subjects.  
 
The use of budesonide-multimatrix (MMx) within the last 8 weeks will exclude subjects. 
 
Subjects with hypersensitivity to salicylates and subjects with moderate/severe renal impairment 
are contra-indicated for treatment with 5-ASA compounds and will be excluded from the study.

 
Subjects with previous treatment biologics (ie, adalimumab, infliximab, vedolizumab, and/or 
other monoclonal antibody) will be excluded from the study. 
Length of Study 
Subjects will spend up to 13 weeks in this study: up to 4 weeks in the Screening Phase; 8 weeks in 
the Double-blind Placebo-controlled Phase; and 1 week in the Follow-up Phase. 
The End of Trial is defined as either the date of the last visit of the last subject to complete the study 
or the date of receipt of the last data point from the last subject that is required for primary, 
secondary, and/or exploratory analysis, as pre-specified in the protocol and/or the Statistical Analysis 
Plan, whichever is the later date. 
Study Treatments 
Subjects will receive 1 of 2 dose regimens of GED-0507-34-Levo in the Double-blind Placebo-
controlled Phase (80 mg BID or 160 mg BID) or placebo BID. GED-0507-34-Levo will be provided 
in 60 mL HDPE bottles as 80 mg tablets. Matching placebo tablets will also be provided. Tablets 
will be taken by mouth BID, morning and evening, approximately 12 hours apart, on an empty 
stomach (ie, at least 3 hours after eating and at least 1 hour prior to eating breakfast or dinner). 
Overview of Efficacy Assessments 
 
MMS at baseline, Week 8, or at the Early Termination Visit 
 
Endoscopy (flexible rectosigmoidoscopy) during the Screening Phase and at Week 8 
 
Histological Assessment of disease activity (Geboes Index), Nancy Index (Marchal-Bressenot et 
al, 2015), and Robarts Index (Mosli et al, 2015) at baseline and at Week 8

INTRODUCTION 
5.1 
Ulcerative Colitis 
Ulcerative colitis (UC) is a chronic, relapsing inflammatory disease of the large intestine 
characterized by inflammation and ulceration of the mucosal and submucosal intestinal layers. It 
is one of the most common forms of inflammatory bowel disease (IBD). The worldwide 
incidence of UC is 1.2 to 20.3 cases per 100,000 persons per year, and its prevalence is 7.6 to 
246.0 cases per 100,000 persons per year (Danese et al, 2011). Clinical characteristics include 
rectal bleeding, diarrhea, and abdominal pain, as well as extraintestinal manifestations involving 
the skin, liver, and other sites (Danese et al, 2011). Patients with UC often have a poor quality of 
life and are at risk for disease flares leading to hospitalizations and/or surgeries. 
The main objectives of treatment in patients with UC are to induce and maintain the remission of 
symptoms and mucosal inflammation in order to improve patients’ quality of life. Treatment of 
UC currently involves pharmacological therapy and surgery, which is indicated when 
pharmacological treatment fails or when a surgical emergency (eg, perforation of the colon) 
occurs. Pharmacological treatment usually involves aminosalicylates and glucocorticoids as an 
initial approach. Various immunosuppressants, as well as biological tumor necrosis factor (TNF) 
blockers and the more recently approved biologics (ie, vedolizumab and etrolizumab), are used 
in refractory or severe disease. Although these drugs can provide clinical benefit, they have 
important limitations. Aminosalicylates are only modestly effective. Glucocorticoids can cause 
unacceptable adverse events (AEs) and do not provide a benefit as maintenance therapy. 
Additionally, immunosuppressant use has been restricted to maintenance therapy and is also 
associated with significant potential toxicities. The TNF blockers, although efficacious, 
predispose patients to serious infections (including opportunistic infections) and possibly 
malignancies (Kornbluth et al, 2010; Mariette et al, 2011).  
5-Aminosalicylic acid (5-ASA) is the standard treatment for induction of remission in patients 
with mild-to-moderate UC. Despite the development of oral advanced formulations, the use of 
high dosages of 5-ASA required for the treatment of UC results in intakeof multiple large-size 
tablets per day.  
Thus, there is a medical need to develop a new anti-inflammatory agent able to induce remission 
in active, mild-to-moderate UC and to maintain the remission, with at least a comparable rate of 
success but at significantly lower doses of active product than 5-ASA. A new anti-inflammatory 
agent, at lower doses and with smaller tablets, which may improve the patient’s compliance, 
could increase the rate of anti-inflammatory treatment responders, thus avoiding the use of 
corticosteroids and immunosuppressive drugs in UC.  
5.2 
Results of Non-clinical Studies 
GED-0507-34-Levo is a small molecule designed to selectively target inflammatory pathways. 
GED-0507-34-Levo anti-inflammatory activity has been demonstrated in vitro in several cell 
lines and in vivo in mouse models of induced colitis. Non-clinical pharmacology studies have 
shown that GED-0507-34-Levo exerts its anti-inflammatory properties in intestinal epithelial 
cells through inhibition of production of pro-inflammatory mediators such as TNFα and

interleukin-8 (IL-8), in a peroxisome proliferator-activated receptor gamma (PPARγ)-dependent 
manner. In vivo, the administration of GED-0507-34-Levo to murine models of induced colitis 
markedly reduced the severity of inflammation both at a macroscopic and histologic level. 
In safety pharmacology studies, GED-0507-34-Levo did not show any effect on the central 
nervous system (Irwin’s test) and on the respiratory function in rats up to the dose of 
2000 mg/kg, which was the no-observed-effect-level (NOEL). In the human ether-a-go-go-
related gene (hERG) assay, no effect on the IKr channel was observed up to the concentration of 
1000 µM. GED-0507-34-Levo did not show any effect on cardiovascular parameters and body 
temperature in a telemetry study in dogs up to the single dose of 2000 mg/kg, which was 
therefore the NOEL. Furthermore, no changes in electrocardiogram (ECG) parameters (including 
QT and QTc [corrected QT interval]) were seen after 14-day repeated administrations in dogs up 
to the dose of 2000 mg/kg/day. 
Across the animal species investigated (rats and dogs), GED-0507-34-Levo showed a low 
clearance accounting for about 34% and 14% of the hepatic blood flow in rats and dogs, 
respectively. The volume of distribution was limited in the rat (about one-half of the total body 
water), while in the dog it was about 5 times higher than the total body water. Terminal half-lives 
of about 0.23 and 8 hours were estimated in rats and dogs, respectively. 
Following single oral administration in male rats, the compound showed a limited oral 
bioavailability (11.5%), whilst in dogs it resulted much higher either formulated with gelatin 
capsules (56%) or Methocel/Tween 80 (92%), with terminal half-life of about 4-5 hours. 
Systemic exposure was assessed in all toxicity studies. Either in rats or in dogs, negligible 
accumulation of both maximum plasma concentration (Cmax) and area under the curve from time 
0 to 24 hours (AUC0-24) values was observed after 14-day or 3-month repeated oral 
administrations. In both animal species, either on Day 1 or on the day of the last administration, 
Cmax and AUC0-24/AUC0-t(last) increased with the dose. No major gender differences were 
observed in both species after repeated administration.  
No significant chiral inversion was observed in rats and dogs following 13-week administration 
of GED-0507-34-Levo. Plasma protein binding was low (less than 13%) and concentration 
independent. 
In vivo, the only metabolite detected in plasma and urine of rats was the N-acetyl derivative of 
GED-0507-34-Levo (N-Acetyl-GED-0507-34-Levo). 
In the Good Laboratory Practice (GLP) 14-day toxicity study in rats, GED-0507-34-Levo was 
well tolerated up to the highest dose of 2000 mg/kg/day. In the GLP 13-week toxicity study in 
rats, GED-0507-34-Levo did not cause any mortality or clinical signs up to the highest dose of 
2000 mg/kg/day with a no-observed-adverse-effect level (NOAEL) of 250 mg/kg/day. In the 
GLP 14-day toxicity study in dogs, no mortality occurred up to the highest tested dose of 
2000 mg/kg/day. No treatment-related effects were noted at the dose of 30 mg/kg/day (that was 
therefore the NOAEL in the 14-day toxicity study in dogs). In the GLP 13-week toxicity study in 
the dog, GED-0507-34-Levo was well tolerated up to the dose of 45 mg/kg/day that was the 
NOAEL.

In both rats and dogs, treatment-related changes were observed in the thyroid of animals only 
when high systemic exposure levels were achieved. The 13-week repeat-dose toxicity studies, 
which included a 2-week recovery period, demonstrated that thyroid changes are transitory 
during the dosing period and recover during the dose-free phase. 
The main oral embryofetal developmental toxicity study was performed in rats and rabbits. The 
NOEL for the mother and for embryofetal development and teratogenicity was 2000 mg/kg/day 
in the rat. In the rabbit, 500 mg/kg/day was the NOEL for maternal toxicity and teratogenicity, 
and the same dose was the NOAEL for embryofetal development.  
GED-0507-34-Levo and its N-acetyl metabolite were not genotoxic in the Ames test. In addition, 
GED-0507-34-Levo did not induce chromosome aberrations in human peripheral blood 
lymphocytes in vitro or micronuclei in rat bone marrow cells in vivo. 
5.3 
Results of Clinical Studies in Humans 
The clinical formulation of GED-0507-34-Levo is a solid dosage oral form, a gastro-resistant, 
pH-dependent release tablet designed for colonic release of the drug substance. 
To date, the GED-0507-34-Levo clinical development program for the treatment of UC consists 
of 2 studies: Study GED-0507-01-09, a Phase 1 first-in-human, double-blind, placebo-controlled 
study of a single dose of GED-0507-34-Levo gastro-resistant prolonged release tablets, 
administered at rising doses in healthy volunteers to evaluate safety and pharmacokinetics (PK); 
and Study GED-0507-01-11, a Phase 2a multicenter, single-arm, single-stage, open-label, 
Fleming’s design, early-escape design, proof-of-concept clinical study on the efficacy and safety 
of GED-0507-34-Levo, in patients with active UC. Treatment duration in the Phase 2a study was 
8 weeks; one 80 mg tablet twice per day (BID) was administered, for a total daily dose of 
160 mg per day.  
In the Phase 1 study, no serious adverse events (SAEs) or suspected-unexpected serious adverse 
reactions (SUSARs) were reported during the study. Only 2 AEs were considered possibly 
related to study treatment: transient amylase value increase (shown to be salivary and not 
pancreatic) and headache. In the Phase 2a study, 5 AEs were considered possibly or probably 
related to study medication (possibly related: worsening of UC, stomach ache, nausea, increase 
of creatine phosphokinase [CPK]; probably related: worsening of abdominal symptoms); 3 AEs 
led to permanent discontinuation that were considered by the Investigator to be possibly related 
(worsening of underlying disease, nausea, and stomach ache) and 1 AE that was considered 
probably related (abdominal symptom) led to permanent discontinuation. The clinical safety 
results show that GED-0507-34-Levo is well tolerated, and there were no safety concerns in 
either of the 2 studies.  
In a different therapeutic area, a Phase 1 clinical study was also performed in patients affected by 
psoriasis with GED-0507-34-Levo formulated as cream for topical administration (Study GED-
0507-PSO-01-12). No SAE occurred during the study. GED-0507-34-Levo was well tolerated; 
no patient dropped out during the study and no safety concern was raised. Only one event 
("redness and itch in both treated areas" in a subject of GED-0507-34-Levo 0.5% group) was 
defined as "probably related" to study drug.

5.4 
Rationale for the Current Study GED0507-UC-001 
At the time the Phase 2a study was designed, a 40% remission rate with the active treatment was 
used as assumption, based on the available 5-ASA clinical data in mild-to-moderate UC that 
showed a primary therapeutic success rate up to 70%. The therapeutic success, however, was 
based mainly on evaluation of clinical symptoms only. A consensus of European Crohn and 
Colitis Organization (ECCO) reported that over the years a variety of scoring systems have been 
developed to assess disease activity in UC patients, based both on clinical symptoms and on 
endoscopic findings, making it difficult to compare the results of clinical trials (Travis et al, 
2011). Therefore, the reported remission rates for 5-ASA can vary by as much as 2-fold 
depending on the definition of remission used in the trials. 
In 2012, Romkens reported in a review an analysis of published data, taking into consideration 5-
ASA therapeutic success based on both clinical and endoscopic scores (Romkens et al, 2012). 
Noteworthy, if we take into considerations the results of the trials in which remission is defined 
based on both clinical and endoscopic sub-scores as the Ulcerative Colitis Disease Activity Index 
(UC-DAI) ≤ 1, the 5-ASA mean remission rate in mild-to-moderate UC patients drops down to 
23.37% (range 0%-39%). 
Furthermore, a recent well-designed randomized clinical trial (Sandborn et al, 2012) recruiting 
active mild-to-moderate UC patients (n=509) and using the same definition of primary efficacy 
endpoint as the one used in our GED-0507-01-11 trial reported a placebo response rate of 7.4% 
and a response to active medications (budesonide-MMX® or mesalamine) in a range between 
17.9% (p=0.014) and 12.1% (not statistically significant). These figures are both quite different 
from the remission rates assumed in the Fleming’s design of our study (20% for placebo and 
40% for treatment arms). 
These results suggest that the 14.7% of remission rate in our study might not be far from the 
percentages observed in the study published by Sandborn, despite the higher clinical severity of 
the population included in our trial. 
If a post-hoc revision of the Fleming’s design and assumptions is performed based on the 
recently published figures, ie, considering the remission rates of 20% (Active Treatment) and 5% 
(Placebo), with a one-sided α of 5% and 90% power (1− β), then the revised protocol Fleming’s 
design would recommend a sample size of 34 with a best cut-off of ≥ 5 successes, that is the 
primary endpoint result of the intent-to-treat (ITT) population. 
Moreover, analysis of the per-protocol (PP) population (remission rate 33.3%, clinical 
improvement rate 53.3% with UC-DAI total scores 6.9 [±1.2, median 7] and 4.1 [±3.1, median 4] 
at baseline and Week 8) suggests that GED-0507-34-Levo might be able to induce a clinically 
significant rate of remission of active UC and to improve general conditions as also suggested by 
the score of the physician’s assessment of patient’s condition (PP) that mirrors the improvements 
observed for the secondary endpoints: from 1.8 at baseline to 1.0 at Week 8 (-0.8).

Therefore, the current study GED0507-UC-001 was designed to evaluate the clinical efficacy of 
GED-0507-34-Levo (80 mg BID and 160 mg BID), compared with placebo, in subjects with 
active UC.  
This study will be performed in compliance with the protocol, International Conference on 
Harmonisation (ICH} Good Clinical Practice (GCP), and applicable regulatory requirements. 
5.5 
Benefit / Risk Assessment 
GED-0507-34-Levo is a novel therapeutic product in clinical development for the treatment of 
patients with UC.  
GED-0507-34-Levo is small molecule new chemical entity designed to selectively target 
inflammatory pathways. GED-0507-34-Levo anti-inflammatory activities have been 
demonstrated in vitro in several cell lines and in vivo in mouse models of induced colitis and 
compared to the activity mediated by 5-ASA, the standard treatment for mild-to-moderate UC. 
Both in vitro and in vivo GED-0507-34-Levo shows a higher anti-inflammatory activity as 
compared to 5-ASA in the non-clinical pharmacology studies. Non-clinical pharmacology 
studies have shown that GED-0507-34-Levo exerts its anti-inflammatory properties in intestinal 
epithelial cells through inhibition of production of pro-inflammatory mediators such as TNF-α 
and IL-8. This occurs via up-regulation of IkBα expression and consequent inhibition of NF-κB 
activation in a PPARγ-dependent manner.  
Clinical safety data are available from the subjects enrolled in the completed Phase 1 and 
Phase 2a clinical studies. The clinical data collected so far were obtained with a gastro-resistant 
80 mg tablet whose release was prolonged during time. Single doses up to 320 mg/day were 
tested in healthy volunteers in the Phase 1 study, and 8-week administration of 160 mg/day dose 
was tested in UC subjects in the Phase 2a trial. Adverse events considered possibly or probably 
related to GED-0507-34-Levo included transient amylase value increase (shown to be salivary 
and not pancreatic), headache, worsening of UC, stomach ache, nausea, increase of CPK, and 
worsening of abdominal symptoms. All related AEs were mild in intensity except the high 
amylase value, which was considered severe. Otherwise, GED-0507-34-Levo appeared to be safe 
and well tolerated.   
The present Phase 2 clinical study GED-0507-UC-001 will explore the efficacy and safety of 
2 dose levels of GED-0507-34-Levo (80 mg BID and 160 mg BID), compared with placebo, in 
subjects with active UC. The doses have been selected mainly based on the results obtained in 
the completed Phase 2a Fleming design study. In the Phase 2a study GED-0507-34-Levo was 
well tolerated and, when the population of subjects who completed the 8-week treatment is taken 
into consideration, a 33% induction of remission rate is observed. However, many subjects either 
dropped out or withdrew early from the study, due to no effect or to worsening of the disease 
within the first 4 weeks of treatment. In the upcoming Phase 2 dose-finding study, in which a 
mild-to-moderate population will be included, the same dose of 160 mg/day used in the Phase 2a 
study (where a population with a higher severity grading was enrolled) and a higher (double) 
dose (320 mg/day) have been selected.

Page 24 
In the upcoming Phase 2 clinical trial, a slightly different oral formulation of GED-0507-34-
Levo will be employed. The new formulation is a gastro-resistant delayed-release 80 mg tablet, 
designed as the previous one for the local delivery of the drug substance in the colon by making 
use of pH-dependent coating polymers. Based on the composition of the tablet, taking into 
consideration the PK profile of these colon release formulations with limited systemic exposure, 
and in analogy with 5-ASA formulations on the market (ie, 5-ASA-MMx and Asacol), no 
significant difference in the PK parameters with the GED-0507-34-Levo new formulation having 
an impact on safety are expected. However, to account both for the use of the new formulation 
and for the administration of a 320 mg/day dose (160 mg BID) for 8 weeks, as agreed during the 
pre-IND meeting (PIND) 126320, an Independent Safety Evaluation will be performed in an 
initial cohort of subjects before enrolling more subjects in the 320 mg/day (160 mg BID) high 
dose.  
Based on the incidence of UC, on the limited percentage of subjects who respond clinically and 
endoscopically to the available anti-inflammatory therapies, and on the side effects that may be 
elicited by immunosuppressants, immunomodulators, and anti-TNF therapies, there is clearly a 
medical need for new treatments for (mild-to-moderate) UC subjects. Moreover, currently 
available anti-inflammatory therapies for UC are formulated as large tablets that negatively 
impact subject compliance. Therefore, a new anti-inflammatory agent for the treatment of mild-
to-moderate UC, to be administered in the form of small gastro-resistant delayed-release tablets 
for the delivery of the drug substance in the colon, would represent an important achievement in 
the treatment of this pathology. 
Overall, based on the medical need and on the available GED-0507-34-Levo safety, tolerability, 
and efficacy data, the proposed Phase 2 clinical trial design is considered appropriate and 
potential benefits of evaluating GED-0507-34-Levo in the Phase 2 study outweigh the perceived 
risks.

OVERALL STUDY DESIGN 
8.1 
Study Design 
This is a Phase 2, multicenter, randomized, double-blind, placebo-controlled, parallel-group 
study to evaluate the efficacy and safety of 2 doses of GED-0507-34-Levo in subjects with 
active, mild-to-moderate UC (defined as an MMS of ≥ 4 to ≤ 8, with a Stool Frequency sub-
score ≥ 1, an RBS = 1 or 2, and an endoscopic sub-score > 1 and < 3). 
Approximately 207 subjects (69 subjects per arm) will be randomized in a 1:1:1 ratio using an 
Interactive Web Response System (IWRS) to receive oral GED-0507-34-Levo (80 mg BID or 
160 mg BID) or identically appearing placebo BID for up to 8 weeks. Treatment will be assigned 
via IWRS. 
The study will consist of 3 parts:  
 In Part 1, 24 subjects will be randomized with 8 subjects per treatment group. The Safety 
evaluation (clinical, hematological, and biochemistry) on these 24 subjects will be 
assessed by an Independent Safety Committee.  
 After the 24th subject is enrolled in Part 1, then Part 2 will start in which new subjects 
will be randomized only in the 80 mg BID and placebo groups in a 1:1 ratio. 
 Once the 24 subjects in Part 1 have completed 8 weeks of treatment and the Safety 
evaluation has been completed with no safety concerns, then Part 3 will continue to 
enroll subjects randomized into all 3 treatment groups. An unequal randomization will 
be used in Part 3 of the study in order to ensure approximately equal numbers of 
subjects randomized into each of the 3 treatment groups across the 3 study parts. 
The study will consist of 3 phases: 
 Screening Phase – up to 4 weeks 
 Double-blind Placebo-controlled Phase – Week 0 to Week 8 
 Follow-up Phase – Week 9 
 
8.1.1 
Safety/PK Sub-studies 
Safety will be assessed on the first 24 randomized subjects (8 in 160 mg/day, 8 in 320 mg/day, 
and 8 in Placebo group) by an Independent Safety Committee before more subjects in the high 
dose group are enrolled in the study. 
After enrollment of subject number 24, and until the Independent Safety Evaluation is complete, 
enrollment will continue and subjects will be randomized in the placebo and 80 mg BID (160 
mg/day) dose groups. 
Upon completion of the Independent Safety Evaluation and provided a positive safety outcome is 
obtained, enrollment of subjects in the 3 dose groups will be performed until end of study.

A PK sub-study will be conducted at selected sites. The target for the PK sub-study is to achieve 
participation of approximately 50% of the randomized subjects  
8.1.2 
Double-blind Placebo-controlled Phase 
Eligible subjects will enter the Double-blind Placebo-controlled Phase for 8 weeks, at the 
Baseline Visit (Week 0, Visit 2). Subjects will be randomly assigned to study treatment as 
described above. All subjects will receive high-density polyethylene (HDPE) bottles of identical 
appearance to maintain blinding. Subjects will continue to receive the treatment assigned at 
baseline for 8 weeks. 
8.2 
Internal PPM SERVICES SA Safety Monitoring During the GED-0507-34-Levo 
Program 
In addition to ongoing safety monitoring conducted by Investigators and individual study 
personnel, cumulative and interval blinded AEs, SAEs, discontinuations due to AEs, and 
abnormal laboratory findings will be reviewed internally by the Safety Management Team 
(SMT). The review follows the Council for International Organizations for Medical Sciences, 
Working Group VI (CIOMS VI) recommendations. The SMT is comprised of lead 
representatives from multiple PPM SERVICES SA functions engaged in the GED-0507-34-Levo 
development program. The scope, conduct, processes, and accountabilities of the SMT are 
specified in the SMT charter. 
8.3 
Internal Data Safety Monitoring Board During the Study 
Unblinded safety data will be reviewed periodically by an internal data safety monitoring board 
(DSMB) at PPM SERVICES SA that is independent of the study team. The external data 
monitoring committee (DMC; Section 8.4) may be convened ad hoc at the request of the DSMB. 
8.4 
External Safety and Efficacy Monitoring During GED-0507-34-Levo Program 
Monitoring will also be performed by an independent, external DMC that will assess safety as 
outlined in the DMC charter (available upon request) after 24 randomized subjects: 8 treated 
with 160 mg/day (80 mg BID), 8 with 320 mg/day (160 mg BID), and 8 with placebo. The DMC 
is comprised of 3 independent external trialists and an independent, external statistician, for 
whom there is no identified conflict of interest. The DMC will be convened approximately every 
12 months or ad hoc at the request of the DSMB or SMT. The DMC scope, conduct, processes, 
and accountabilities are pre-specified in its charter. Recommendations of the DMC based on the 
overall benefit/risk evaluation may include proceeding with the study per protocol, proceeding 
with the study with modification, or study suspension. 
8.5 
Study Design Rationale 
This study represents the second investigation of GED-0507-34-Levo in subjects with UC. This 
study will provide information on the safety and clinical efficacy in the UC population prior to 
advancing to larger clinical trials, as well as provide critical information for the design of future 
studies in this population.

The purpose of this study is to determine whether GED-0507-34-Levo is effective and safe in the 
treatment of subjects with active UC. The primary measure of efficacy will be clinical remission 
determined by the MMS in a double-blind, placebo-controlled study at Week 8. Clinical 
remission is defined as an MMS ≤ 2, with no individual sub-score > 1, at Week 8. The laboratory 
results, AEs, vital signs, ECGs, pregnancy tests, and physical examinations will be monitored to 
evaluate safety. 
A schematic diagram illustrating the study design is shown in Figure 1. 
8.6 
Study Duration 
Subjects will spend up to 13 weeks in this study: up to 4 weeks in the Screening Phase; 8 weeks 
in the Double-blind Placebo-controlled Phase; and 1 week in the Follow-up Phase. 
8.7 
End of Trial 
The End of Trial is defined as either the date of the last visit of the last subject to complete the 
study or the date of receipt of the last data point from the last subject that is required for primary, 
secondary, and/or exploratory analysis, as pre-specified in the protocol and/or the Statistical 
Analysis Plan (SAP), whichever is the later date.

a. 
Subjects who discontinue from the study prior to the Week 8 Visit will have an Early Termination Visit. 
b. 
The female subject's chosen form of contraception must be effective by the time the female subject is randomized into the study (for example, hormonal 
contraception should be initiated at least 28 days before randomization). Serum pregnancy tests will be performed at screening, and urine pregnancy testing 
will be done at all remaining visits, including an Early Termination Visit. Urine pregnancy test kits will be provided to the site. A pregnancy test(s) should 
be administered if the subject misses a menstrual period during the study treatment period. 
c. 
Sparse PK samples as described in Section 9.9.1.  
d. 
The screening endoscopy will consist of a colonoscopy or flexible rectosigmoidoscopy. Colonoscopy is required at screening only for those subjects who 
have not had a colonoscopy within 12 months prior to the Screening Visit. Rectosigmoidoscopies will be repeated at Week 8 or at the Early Termination 
Visit. 
e. 
Rectosigmoidoscopy will not be repeated if within 4 weeks of the previous endoscopy. 
f. 
Two intestinal mucosal biopsies will be performed with the endoscopy during the Screening Phase and also at the Week 8 Visit or the Early Termination 
Visit if the subject discontinues prior to Week 8. Biopsies should be taken from the most inflamed area of the rectum or rectosigmoid junction, while 
avoiding ulcerated mucosa. Week 8 biopsies should be taken from the same location as the baseline biopsy.

PROCEDURES 
The following procedures/assessments will be conducted according to the schedule indicated in 
Table 1 Schedule of Events. 
9.1 
Informed Consent 
An informed consent form (ICF) must be signed by the subject before any study-related 
assessments are performed. In addition, the randomized subjects must consent specifically for the 
PK sub-study. Details of the informed consent process may be found in Section 17.3. 
9.2 
Contraception Education 
The risks to a fetus or to a nursing child from GED-0507-34-Levo are not known at this time.  
A female of childbearing potential (FCBP) is a sexually mature female who 1) has not undergone 
a hysterectomy (the surgical removal of the uterus) or bilateral oophorectomy (the surgical 
removal of both ovaries) or 2) has not been postmenopausal for at least 24 consecutive months 
(that is, has had menses at any time during the preceding 24 consecutive months). 
All FCBP must use one of the approved contraceptive options as described in Section 10.2 while 
on IP and for at least 28 days after administration of the last dose of the IP. 
At the time of study entry, and at any time during the study when an FCBP’s contraceptive 
measures or ability to become pregnant changes, the Investigator will educate the subject 
regarding contraception options and correct and consistent use of effective contraceptive 
methods in order to successfully prevent pregnancy. 
9.3 
Medical and Disease History 
Relevant medical history should be recorded, including caffeine consumption, smoking and 
alcohol history, as well as previous relevant surgeries. Disease history includes history of UC 
(i.e, the disease under study). 
9.4 
Inclusion/Exclusion Criteria 
Subjects must meet all inclusion criteria (Section 10.2) and must not have any of the conditions 
specified in the exclusion criteria (Section 10.3) to qualify for participation in the study. The 
subject’s source documents must support his/her qualifications for the study (eg, if a female 
subject does not require pregnancy testing and birth control because of a hysterectomy, the date 
of the hysterectomy must be included in the medical history). 
 
9.5 
Prior/Concomitant Medications and Therapies 
All medications (prescription and nonprescription, including vitamins) taken by the subject up to 
30 days prior to the Screening Visit (Visit 1) should be recorded, including the stop dates for 
medications prohibited in the study. All medications taken by the subject at any time during the 

GED-0507-34-Levo 
 
CONFIDENTIAL 
Protocol GED0507-UC-001 
 
FINAL VERSION 2.0 - PPM 24-January-2017

study must also be recorded. Other key medications and therapies, such as previous treatment for 
tuberculosis or relevant diseases, should also be recorded. 
9.6 
Safety Assessments 
9.6.1 
Serum and Urine Pregnancy Tests for Females of Childbearing Potential 
A urine pregnancy test will be performed on all FCBP at the Baseline Visit, all onsite visits, and 
at Follow-up or at the Early Termination Visit. A urine pregnancy test kit will be provided by the 
central laboratory. Pregnancy tests should be performed if the FCBP has missed a menstrual 
period or the contraception method has changed. 
9.6.2 
Hepatitis B and C 
The hepatitis screen includes testing for hepatitis B surface antigen and antibody, hepatitis B 
core antibodies (immunoglobulin G [IgG]/immunoglobulin M [IgM]), and antibodies to 
hepatitis C. 
9.6.3 
Vital Signs, Height, and Weight 
Vital signs, including temperature, pulse, and seated blood pressure, will be taken during the 
visits indicated in Table 1 Schedule of Events. Height will be measured and recorded at 
screening; weight will also be measured and recorded at screening and then as indicated in 
Table 1 Schedule of Events. Body mass index (BMI) will be calculated at screening. 
9.6.4 
Physical Examinations 
Complete physical examinations will include evaluation of the skin, respiratory, cardiovascular, 
abdominal, neurological, lymphatic, and musculoskeletal systems. Results of the physical 
examinations will be recorded only in the source documents. 
Clinically significant abnormal findings (with the exception of the disease under study [UC]) 
identified prior to first dose of IP will be recorded on the electronic case report form (eCRF) as 
medical history; clinically significant findings after the first dose of IP will be recorded as AEs. 
Note: Gynecological and urogenital examinations will not be performed unless for cause. 
9.6.5 
Stool Culture / Microbiology 
Stool culture analysis and assessment of Clostridium difficile toxin will be performed at the 
Screening Visit, as well as Salmonella, Shigella, Yersinia, Aeromonas, Plesiomonas, or 
Campylobacter. Subjects who are initially positive for C. difficile may re-screen for the study 
after they have successfully completed therapy and had 2 months of consecutive negative tests 
for C. difficile.

9.6.6 
12-lead Electrocardiogram 
The 12-lead ECG will be performed after the subject has been supine for approximately 
3 minutes. Sites are to utilize their own local ECG machines for the study, and the automated 
ECG readings will be further interpreted by the Investigator by clinically correlating them with 
the subject’s condition. The Investigator’s clinical interpretation will be recorded in the eCRF as 
one of the following: “normal”, “abnormal, not clinically significant”, or “abnormal, clinically 
significant”. “Abnormal, clinically significant” results should be recorded in the Medical History 
eCRF if found prior to the first dose of IP or in the AE eCRF if found after the first dose of IP. 
9.6.7 
Clinical Laboratory Evaluations 
A central laboratory will be used for this study. Clinical laboratory evaluations will include the 
following: 
 Hematology: complete blood count (red blood cell [RBC] count, hemoglobin, 
hematocrit, white blood cell [WBC] count and differential, absolute WBC counts, 
platelet count) 
 Serum chemistries: total protein, albumin, calcium, phosphorous, glucose, total 
cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) 
cholesterol, triglycerides, uric acid, total bilirubin, alkaline phosphatase, aspartate 
aminotransferase (AST)/ serum glutamic oxaloacetic transaminase (SGOT), alanine 
aminotransferase (ALT)/ serum glutamic pyruvic transaminase (SGPT), sodium, 
potassium, chloride, carbon dioxide, blood urea nitrogen (BUN), creatinine, lactate 
dehydrongenase (LDH), magnesium, amylase (pancreatic) 
 Urinalysis: dipstick urinalysis (specific gravity, pH, glucose, ketones, protein, blood, 
bilirubin, leukocyte esterase, nitrite, and urobilinogen) 
o Microscopic urinalysis (epithelial cells, RBC, WBC, and casts) will be performed 
only if the dipstick urinalysis is abnormal 
Note: Clinical laboratory evaluations are not required to be fasting. However, the site will record 
whether a clinical laboratory evaluation was fasting or nonfasting on the lab requisition form. 
9.6.8 
Adverse Events 
Adverse events (Section 14.1) will be recorded by the Investigator from the time the subject 
signs informed consent to 28 days after the last dose of IP. The AEs, including SAEs, will be 
recorded on the AE page of the eCRF and in the subject’s source documents. All SAEs must be 
reported to PPM SERVICES SA Drug Safety within 24 hours of the Investigator’s knowledge of 
the event (see Section 14.5). Worsening of a subject’s UC, including UC flare, should be 
considered as worsening of disease under study, and should not be captured as an AE. 
Worsening or exacerbation of UC, including UC flare, meeting the definition of an SAE should 
be reported as an SAE.

Efficacy Assessments 
9.7.1 
Subject Diary for Ulcerative Colitis Disease Activity 
Subjects will be provided with the Subject Diary for UC Disease Activity at study visits in order 
to record the following information: 
 
(1) Frequency of bowel movements: 
As usual 
1-2 times a day more than usual 
3-4 times a day more than usual 
More than 5 times a day more than usual 
 
(2) Blood in stools 
Absent 
Traces of blood in stools 
A lot of blood in stools 
Blood only 
 
(3) General Well-Being 
Generally Well 
Fair 
Poor 
Terrible 
Diaries will be completed throughout the study and assessed at the clinic, at each study visit, 
from screening until the Week 8 Visit or Early Termination Visit. The information extracted will 
be used for calculation of the Mayo score. In order to encourage consistent diary recording, 
subjects are required to enter diary data continuously throughout the study. The method of diary 
data collection will be electronic data capture and may include paper. 
9.7.2 
Endoscopy 
The screening endoscopy may consist of either a flexible rectosigmoidoscopy or a colonoscopy. 
A colonoscopy is required during the Screening Phase only for those subjects who have not had a 
colonoscopy within 12 months prior to the Screening Visit. Subsequent endoscopies 
(rectosigmoidoscopies) will be performed at Week 8 or at the Early Termination Visit. The 
flexible rectosigmoidoscopy will not be repeated within 4 weeks of the previous 
rectosigmoidoscopy. 
Images/Videos of all endoscopic procedures (flexible rectosigmoidoscopy/colonoscopy) will be 
captured and sent to a centralized reader for their assessment, which will be used for the 
calculation of the MMS. The endoscopy assessment performed by the Investigator will be used

Protocol GED0507-UC-001 
 
FINAL VERSION 2.0 - PPM 24-January-2017 
Page 38 
to calculate the MMS for the determination of subjects who do not achieve at least a 20% 
decrease from baseline in the MMS at Week 8. 
Mucosal biopsies, collected for assessment of histological disease activity (Section 9.8), will be 
performed during the Screening Phase and at the Week 8 Visit when the endoscopies are done. 
Biopsies should be taken from the most inflamed area of the rectum or rectosigmoid junction, 
while avoiding ulcerated mucosa. Week 8 biopsies should be taken from the same location as the 
baseline biopsy. Subjects who discontinue study prior to the Week 8 Visit will have the biopsies 
performed at the Early Termination Visit with the endoscopy. 
Central reading of endoscopies will be performed throughout this study, and a detailed charter 
will address the standardization of endoscopic procedures, video recordings, and equipment, as 
well as the criteria for endoscopic assessment. For each subject, video recording of the entire 
endoscopic procedure will be performed. Annotation of the rectum, sigmoid and descending 
colon will be performed by the site endoscopist on withdrawal, using the equipment provided. 
All video recordings will be quality checked by the central read vendor to produce a video clip 
visualized up to the splenic flexure only (rectum, sigmoid, and descending colon). The video 
clips will be read centrally for mucosal lesions and endoscopic severity by an independent 
gastroenterologist experienced in IBD who is blind to the subject’s clinical activity and treatment 
allocation. The Mayo Clinic Score (MCS) endoscopic sub-score is to be determined both locally 
(at the investigator site) and centrally as described above. Each segment of the colon up to the 
splenic flexure (rectum, sigmoid, and descending colon) will be assigned an endoscopic sub-
score, and the score from the worst affected segment up to the splenic flexure is to be used for 
the MCS calculation. In the event that there is a discrepancy between the endoscopic sub-score 
obtained by the local versus the central readers, a third adjudication read is to be conducted by a 
different central reader.  
Training of the site and central readers, and the adjudication process in the event of a 
discrepancy between site and central reader; will be described in detail in the Endoscopy charter 
9.7.3 
Modified Mayo Score 
The Mayo Score is an instrument designed to measure disease activity of UC. The Mayo Score 
ranges from 0 to 12 points. It consists of 4 sub-scores, each graded from 0 to 3 with higher scores 
indicating more severe disease (Appendix C). 
A modification to the Total Mayo Score (TMS) will be implemented in this study. This MMS 
will be based on the stool frequency, rectal bleeding, and endoscopy sub-scores of the TMS and 
will exclude the Physician’s Global Assessment (PGA) sub-score, since this is a global measure 
that is subjective in nature. The MMS ranges from 0 to 9 points. Clinical response is defined as a 
decrease from baseline in modified Mayo Score of at least 2 points and at least 25%, with an 
accompanying decrease in the RBS of at least 1 point or an absolute RBS of 0 or 1. Clinical 
remission is defined as an MMS of 2 points or lower, with no individual sub-score exceeding 1 
point.

Peripheral blood will be analyzed for CRP, which is a protein that provides an objective criterion 
of inflammatory activity. C-reactive protein enables identification of subjects with UC symptoms 
who have objective evidence of active inflammatory disease (Sands 2015). Fecal calprotectin, a 
biomarker of intraluminal intestinal inflammation, will be assessed by a central reader. Fecal 
calprotectin is a directly proportional measurement of neutrophil migration to the gastrointestinal 
(GI) tract. The schedule and frequency of PD/biological markers are discussed in Table 1 
Schedule of Events. 
Intestinal mucosal biopsies will be performed during endoscopy as indicated in Table 1 Schedule 
of Events in order to assess inflammatory cell infiltration and tissue destruction in the colonic 
mucosa. One biopsy will be stained with Haematoxylin Eosin (H&E), and the degree of cellular 
inflammatory infiltrate and of tissue destruction present in the colonic mucosa will be measured 
using a microscopic tissue grading score.  
9.9 
Pharmacokinetics 
A PK sub-study will be conducted at selected sites to evaluate the PK profile of GED-0507-34-
Levo (parent compound) and N-Acetyl-GED-0507-34-Levo (metabolite) in subjects with active 
UC and to explore the relationship between GED-0507-34-Levo PK exposures and key efficacy 
endpoints. The target for the PK sub-study is to achieve participation of approximately 50% of 
the randomized subjects. A separate consent will be signed for this assessment at the Screening 
Visit. 
Pharmacokinetic measurements will be carried out by Accelera Srl (Viale Pasteur 10, 20014 
Nerviano, Milano, Italy) using a validated method for the detection of GED-0507-34-Levo and 
its metabolite N-Acetyl-GED-0507-34-Levo in Human Plasma by liquid chromatography – 
tandem mass spectroscopy (LC-MS/MS). 
9.9.1 
Pharmacokinetics Blood Draw 
For each subject participating in the PK sub-study, the date and time of his/her first dose will be 
recorded in the source documents and eCRF.

The subjects participating in the PK sub-study will have 4 blood specimens drawn (1 predose 
during the treatment and 3 postdose). For the predose blood draw, the subject must be reminded 
to provide the date and time of his/her last evening dose from the day before the visit, which will 
be recorded in the source documents and eCRF together with the blood draws prior to the 
morning intake of the compound. 
Postdose plasma population PK samples should be taken at a random time between 2 to 4 hours 
postdose, > 4 to 6 hours postdose, and > 6 to 10 hours postdose. The date and time of his/her 
dose prior to the blood draws and the date and time of blood draws will be recorded in the source 
documents and eCRF.  
PK blood draws are to take place in the clinic at Visits 4 (Week 2), 5 (Week 4), 6 (Week 6), and 
7 (Week 8). It is recommended that subjects have 1 blood specimen collected from each of these 
time windows over the course of the PK sub-study.  
Specific details regarding collection, handling, processing, storage, and shipment of PK samples 
will be presented separately.

Dosing 
9.10.1 
Investigational Product Dispensing and Counting 
After the subject has satisfied all inclusion and exclusion criteria, IP will be dispensed as 
specified by the IWRS. Subjects must be instructed to return all previously issued empty HDPE 
bottles and/or unused IP at the time that new IP is issued. A detailed record of tablets issued and 
returned at each visit must be maintained in the subject’s record. 
9.11 
Early Termination Visit 
The Early Termination Visit is based on the subject’s withdrawal from the study prior to Week 8. 
Participation in the study is completely voluntary. Subjects are also free to withdraw from the 
study at any time if they feel they are not benefiting from the study in order to receive rescue 
therapy and/or receive treatment with standard medical care. In addition, the Investigator may 
discontinue the subject from the study at any time based on his/her assessment of clinical 
efficacy and/or safety. The decision to discontinue a subject remains the responsibility of the 
treating physician, which will not be delayed or refused by the sponsor. When a subject 
withdraws or is discontinued from the study, every effort should be made to complete as many 
safety and efficacy assessments as reasonably appropriate. Refer to Table 1 for the assessments 
to be performed at the Early Termination Visit. 
9.11.1 
Lost to Follow-up 
Subjects will be considered lost to follow-up when they fail to attend study visits without stating 
an intention to withdraw from the study. The Investigator should show due diligence by 
documenting in the source documents the steps taken to contact the subject through at least 2 
telephone calls and/or emails and 1 registered letter. After all reasonable attempts have been 
made to contact the subject, the subject should be recorded as “lost to follow-up” in the eCRF.

11 DESCRIPTION OF STUDY TREATMENTS 
11.1 
Description of Investigational Product(s) 
The chemical name of GED-0507-34-Levo (GED0507) is (S)-(-)-3-(4-aminophenyl))-2-
methoxypropionic acid. 
GED-0507-34-Levo will be provided as 80 mg tablets. Placebo will be provided as identically 
appearing tablets. 
11.2 
Treatment Administration and Schedule 
Tablets will be taken by mouth BID, in the morning (AM) and in the evening (PM), 
approximately 12 hours apart, on an empty stomach (ie, at least 3 hours after eating and at least 1 
hour prior to eating breakfast or dinner). 
80 mg BID group: 2 tablets AM (1 placebo + 1 active 80 mg) and 2 tablets PM 
(1 placebo + 1 active 80 mg). 
160 mg BID group: 2 tablets AM (2 active 80 mg) and 2 tablets PM (2 active 80 mg). 
Placebo Group: 
2 tablets AM and 2 tablets PM. 
11.3 
Method of Treatment Assignment 
After the ICF is signed, subjects will be assigned a subject identification number using a 
centralized IVRS/IWRS. At the Baseline Visit, a centralized schema will be applied to assign 
subjects who meet the inclusion/exclusion criteria in a 1:1:1 ratio to receive GED-0507-34-Levo 
80 mg by mouth (PO) BID, 160 mg PO BID, or placebo. 
Designated study personnel at the investigational sites will be assigned password-protected, 
coded identification numbers that give them authorization to connect to IWRS to randomize 
subjects. The system will present a menu of questions by which the study personnel will identify 
the subject and confirm eligibility. When all questions have been answered, the IWRS will 
assign a randomization identification number. 
During the study visits, the pharmacy or authorized study personnel at the investigational site 
will dispense coded IP kits in accordance with the randomization number assigned by the IWRS. 
11.4 
Packaging and Labeling 
All IP, including placebo and GED-0507-34-Levo tablets, will be supplied by PPM SERVICES 
SA (or designee) to the principal Investigator as HDPE bottles during the Double-blind Placebo-
controlled Phase. 
GED-0507-34-Levo will be provided in HDPE bottles as 80 mg tablets.. Tablets will be taken by 
mouth BID, morning and evening, approximately 12 hours apart, on an empty stomach (ie, at 
least 3 hours after eating and at least 1 hour prior to eating breakfast or dinner).

The label(s) for IP will include the protocol number, IP name, dosage form and strength (where 
applicable), amount of IP per container, lot number, expiry date (where applicable), medication 
identification/kit number, dosing instructions, storage conditions, and required caution 
statements and/or regulatory statements as applicable. Additional information may be included 
on the label as applicable per local regulations. 
11.5 
Investigational Product Accountability and Disposal 
The Investigator, or designee, is responsible for taking an inventory of each shipment of IP 
received and comparing it with the accompanying IP shipping order/packing list. 
The Investigator, or designee, will verify the accuracy of the information on the form, sign and 
date it, retain a copy in the study file, and return a copy to PPM SERVICES SA. 
The IP will be stored according to the storage conditions identified on the drug label. At the 
study site, all IP will be stored in a locked, safe area to prevent unauthorized access. 
PPM SERVICES SA (or designee) will review with the Investigator and relevant site personnel 
the process for IP return, disposal, and/or destruction, including responsibilities for the site 
versus PPM SERVICES SA (or designee). 
11.6 
Investigational Product Compliance 
Study personnel will review the instructions printed on the package with the study subjects prior 
to dispensing the IP. Investigational Product will be dispensed as noted in Table 1 Schedule of 
Events. The subjects will be instructed to return the IP containers, including any unused 
medication, to the study site at each visit for tablet counts and reconciliation. Subjects will be 
asked whether they have taken their IP as instructed at each study visit. Any problems with IP 
compliance will be reviewed with the subject. If a subject misses 4 or more consecutive days of 
dosing, PPM SERVICES SA must be contacted to decide whether dosing should resume or 
whether the subject should be terminated from the study. 
Gross compliance problems (eg, missing 4 or more consecutive days of dosing or taking less 
than 75% of the doses between study visits) should be discussed with PPM SERVICES SA. 
Compliance is defined as taking between 80% and 120% of dispensed IP.

13 STATISTICAL ANALYSES 
13.1 
Overview 
Key elements of the SAP are outlined in this section. The comprehensive plan will be 
documented in a separate SAP. 
13.2 
Study Population Definitions 
Safety analyses will be based on the safety population, which will include all subjects who are 
randomized and receive at least 1 dose of IP. Subjects will be included in the treatment group 
corresponding to the IP they actually received for the analyses using the safety population. 
The ITT population will consist of all subjects who are randomized as specified in the protocol 
and receive at least 1 dose of IP. Subjects will be included in the treatment group to which they 
were randomized, irrespective of the treatment actually received, for the analyses using the ITT 
population. 
The modified intent-to treat (mITT) population is defined as the ITT population with the 
exclusion of the subjects who: a) withdraw from the study due to a reason clearly documented as 
independent of either the study treatment or the UC; or b) remained on study for less than 7 days. 
The mITT population will be the primary population for efficacy analyses. 
The PP population will consist of all subjects included in the mITT population who have at least 
1 post-baseline efficacy evaluation and no protocol violations that may substantially affect the 
efficacy results. The final determination on these protocol violations, and thereby the 
composition of the PP population, will be made prior to the Placebo-controlled Phase analysis 
and will be separately documented. 
The PK population will consist of all subjects in the safety population who have at least one 
analyzable PK sample. It is expected that the PK population will consist of approximately 50% 
of the overall study population. 
13.3 
Sample Size and Power Considerations 
Given that the purpose of this Phase 2a trial is to determine whether the drug is efficacious and 
therefore whether to proceed with further development, there is only 1 outcome of interest: 
superiority of 1 or more experimental arms to the control. In this scenario, a one-sided testing 
framework is appropriate. 
Moreover, given the need for the trial to be small (one or more Phase 3 trials will be required to 
confirm the efficacy), standard type I error rate control at the 2.5% level is not strictly necessary. 
For decisions concerning the future of the project, the sponsor will consider a more relaxed 
approach to false positive rate, allowing a 5% type I error for the one-sided test of the null 
hypothesis (ie, the primary outcome is no different between each treatment group and control) 
rather than the usual 2.5% required for a pivotal trial. The use of this higher type I error and of a 
low type II error of 15% give to the trial a high statistical power to detect the clinically 
meaningful effects while maintaining an acceptable and feasible size. Finally, because this trial is 

GED-0507-34-Levo 
 
CONFIDENTIAL 
Protocol GED0507-UC-001 
 
FINAL VERSION 2.0 - PPM 24-January-2017 
Page 49 
a multiple-experimental arm randomized trial with a control, sample size is increased in order to 
maintain an overall type I error rate as close as possible to the nominal value of 5%. Assuming 
the following: 
 A 6% Clinical Remission rate for the placebo, which after allowing for a 15% dropout 
rate being interpreted as treatment failure, equates to a 5.1% Clinical Remission rate. 
 A 26% Clinical Remission rate for the highest dose of GED-0507-34-Levo (20% more 
than placebo group), which after allowing for a 15% dropout rate being interpreted as 
treatment failure, equates to a 22.1% Clinical Remission rate. 
 A type I (α) error of 0.05. 
 A power of 85%, type II (β) error = 0.15, to detect, if it exists, the above stated 
difference between GED-0507-34-Levo and placebo. 
 A one-tailed test for proportions. 
 A drop-out rate of 15%. 
Fifty five (55) subjects per group are needed. 
However, in order to take into account the multiplicity of the tests and the need of maintaining 
the experiment-wise error at the nominal alpha level, the number of subjects per group is 
increased to 69, for a total of 207 subjects. With this number of subjects, the alpha level actually 
considered is 2.5%, as the Bonferroni-Holm method will require for the significance testing of 
the lower p-value. 
Table 2 shows how the statistical power would change if the Clinical Remission rate in the 
placebo group was different from the estimated 6% (maintaining a 20% greater effect in the 
treatment group before adjustment for dropouts).

Statistical Methods 
The primary efficacy variable is the proportion of subjects who are in Clinical Remission at 
Week 8, as defined by an MMS of ≤ 2, with individual sub-scores (SF and Endoscopy) ≤ 1, and 
RBS = 0.  
GED-0507-34-Levo treatment arms will be compared with placebo using the chi-squared test 
and using the Bonferroni-Holm method to control the false positive error rate. Corresponding 
confidence intervals for the risk ratios of GED-0507-34-Levo against placebo will be presented. 
Subjects who withdraw will be assumed not to be in remission at Week 8. The last-observation-
carried-forward (LOCF) method will be used to impute MMS in the case of missing values in 
subjects completing the study. The above primary analysis does not adjust for the effects of 
center under the assumption that there will be many centers who do not recruit at least 1 subject 
on every treatment. Should this assumption not appear to be the case, the primary analysis 
methodology will be updated in the SAP prior to breaking the blind for the study. 
The primary analysis of the primary efficacy variable will be on the mITT population and will be 
the comparison of each of the GED-0507-34-Levo doses against placebo as described above. 
Additional supportive analysis of the primary efficacy variable will be performed on the ITT and 
PP populations. A further exploratory log-binomial regression analysis will be performed to 
investigate the association of prognostic factors with proportion of subjects in Clinical Remission 
at Week 8. 
Summary statistics will be presented for efficacy variables and their changes from baseline at 
each time point on the mITT, ITT, and PP populations. 
13.5 
Background and Demographic Characteristics 
Subjects’ age, height, weight, and other continuous demographic and baseline characteristics will 
be summarized using descriptive statistics, while gender, race, and other categorical variables 
will be provided using frequency tabulations. Medical history data will be summarized using 
frequency tabulations by system organ class and preferred term. 
13.5.1 
Subject Disposition 
Subject disposition (analysis population allocation, entered, discontinued along with primary 
reason for discontinuation, completed) will be summarized using frequency and percentage. 
Time to withdrawal from the start of study medication will be compared between the three 
treatment groups using Kaplan-Meier curves. 
A summary of subjects enrolled by site will be provided. 
Protocol violations/deviations will be summarized using frequency tabulations.

13.6 
Efficacy Analysis 
The mITT population (Section 13.2) will be the primary population for efficacy analyses. 
Supportive analyses using the ITT and PP populations will also be performed for the primary 
efficacy endpoint. 
The primary efficacy variable is the proportion of subjects achieving a clinical remission in the 
MMS at Week 8, defined as a MMS of ≤ 2 with individual sub-scores (SF and Endoscopy) ≤ 1, 
and RBS = 0. 
The methodology for the primary efficacy analysis is described in Section 13.4. The following 
secondary and exploratory efficacy endpoints will be analyzed using similar methodology. 
 The proportion of subjects achieving clinical response at Week 8, defined as a decrease 
from baseline in the MMS of at least 2 points and at least 25 %, along with a reduction 
in the RBS of at least 1 point or an absolute RBS of ≤ 1 
 The proportion of subjects achieving endoscopic remission at Week 8, defined as a 
Mayo endoscopic sub-score of 0 
 The proportion of subjects achieving endoscopic response at Week 8, defined as a 
decrease from baseline of at least 1 point in the Mayo endoscopic sub-score 
 The proportion of subjects achieving a RBS ≤ 1 at Week 8 
Additional endpoints may be added to the hierarchy and specified in the SAP. 
Summary of all efficacy endpoints over time will be provided using frequency and percentage 
for categorical endpoints and descriptive statistics for continuous endpoints. 
The MMS consists of the SFS, RBS, and endoscopy sub-scores of the TMS and excludes the 
PGA sub-score, since this is a global measure that is subjective in nature. Each of these 
parameters will be assessed on a scale of 0 to 3. The sum of scores for all 3 parameters will 
determine the MMS. The MMS ranges from 0 to 9 points. 
Clinical response is defined as a decrease from baseline in MMS of at least 2 points and at least 
25%, with an accompanying decrease in the RBS of at least 1 point or an absolute RBS of 0 or 1. 
Assessment of sigmoidoscopic appearance will be performed in the worst inflamed area in the 
rectum or in the sigmoid if the rectum is not inflamed. The same area should be evaluated at 
baseline and at the End of Study/Early Withdrawal Visit. 
Images of all endoscopic procedures will be captured and sent to a centralized reader for their 
assessment. 
Improvement of symptoms at Weeks 2, 4, 6, and 8 will be assessed by using 2 individual 
parameters of the MMS: rectal bleeding and stool frequency. Subjects will report details 
regarding rectal bleeding and stool frequency to the electronic diary system every day during the 
study. Assessment of rectal bleeding and stool frequency will be done by the subject. The 
Investigator will calculate the average score of each parameter for the last 3 available days in the

5-day period immediately prior to each clinic visit and record the score in the CRF. No data older 
than 5 days will be used. 
13.7 
Safety Analysis 
Safety and tolerability will be assessed by AEs, laboratory testing (haematology, biochemistry, 
and urinalysis), and vital signs. 
The safety analyses will be performed using the safety population (Section 13.2). Treatment-
emergent AEs will be classified using the Medical Dictionary for Regulatory Activities 
(MedDRA) classification system. All AEs will be summarized by system organ class, preferred 
term, severity, and relationship to IP. Adverse events leading to death or to discontinuation from 
treatment and SAEs will also be tabulated. In the by-subject analysis, a subject having the same 
event more than once will be counted only once and by greatest severity. 
Laboratory data will be summarized descriptively by visit. In addition, shift tables showing the 
number of subjects with values low, normal, and high compared to the normal ranges 
pretreatment versus post-treatment will be provided. 
Vital sign measurements, including weight, will be summarized descriptively by visit and 
presented as shift tables. 
13.8 
Pharmacokinetic Assessments 
Nonlinear mixed effect models will be used for the evaluation of the population PK profile. The 
population PK analysis will be performed using NONMEM® software. The evaluation will be 
performed for describing the PK in the subject population and for identifying the relevant 
demographic and pathophysiological covariates.  
The approach will be based on the development of the following 3 models: 
 Identification of the structural model that best describe the pharmacokinetic data in 
absence of covariates.  
 Random Effect Models: defining the inter-individual variability and the residual error. 
Different forms of residual error (additive, multiplicative or both) will be explored. 
 Covariate Model: identifying the relevant demographic and pathophysiological 
covariates affecting the PK profile of the compound. The selection of the covariates will 
be performed using an appropriate statistical methodology. 
 
13.9 
Pharmacodynamic Assessments 
The relationship between CRP and UC-DAI score will be assessed using scatter plots and 
correlations.

14 ADVERSE EVENTS 
14.1 
Monitoring, Recording and Reporting of Adverse Events 
An AE is any noxious, unintended, or untoward medical occurrence that may appear or worsen 
in a subject during the course of a study. It may be a new intercurrent illness, a worsening 
concomitant illness, an injury, or any concomitant impairment of the subject’s health, including 
laboratory test values (as specified by the criteria in Section 14.3), regardless of etiology. Any 
worsening (ie, any clinically significant adverse change in the frequency or intensity of a pre-
existing condition) should be considered an AE. A diagnosis or syndrome should be recorded on 
the AE page of the eCRF rather than the individual signs or symptoms of the diagnosis or 
syndrome. 
Abuse, withdrawal, sensitivity, or toxicity to an investigational product should be reported as an 
AE. Overdose, accidental or intentional, whether or not it is associated with an AE, should be 
reported on the drug exposure eCRF page. Any sequela of an accidental or intentional overdose 
of an investigational product should be reported as an AE on the AE eCRF. If the sequela of an 
overdose is an SAE, then the sequela must be reported on an SAE report form and on the AE 
eCRF. The overdose resulting in the SAE should be identified as the cause of the event on the 
SAE report form and eCRF but should not be reported as an SAE itself. 
All subjects will be monitored for AEs during the study. Assessments may include monitoring of 
any or all of the following parameters: the subject’s clinical symptoms; weight loss; diarrhea; 
laboratory; pathological; radiological or surgical findings; physical examination findings; or 
findings from other tests and/or procedures. 
All AEs will be recorded by the Investigator from the time the subject signs informed consent 
until 28 days after the last dose of IP, and those SAEs made known to the Investigator at any 
time thereafter that are suspected of being related to IP. Adverse events and SAEs will be 
recorded on the AE page of the CRF and in the subject’s source documents. All SAEs must be 
reported to PPM SERVICES SA Drug Safety within 24 hours of the Investigator’s knowledge of 
the event by facsimile, or other appropriate method, using the SAE Report Form, or approved 
equivalent form. 
14.2 
Evaluation of Adverse Events 
A qualified Investigator will evaluate all AEs as to: 
14.2.1 
Seriousness 
An SAE is any AE occurring at any dose that: 
 Results in death; 
 Is life-threatening (ie, in the opinion of the Investigator, the subject is at immediate risk 
of death from the AE); 
 Requires inpatient hospitalization or prolongation of existing hospitalization 
(hospitalization is defined as an inpatient admission, regardless of length of stay); 

GED-0507-34-Levo 
 
CONFIDENTIAL 
Protocol GED0507-UC-001 
 
FINAL VERSION 2.0 - PPM 24-January-2017 
Page 55 
 Results in persistent or significant incapacity/disability (a substantial disruption of the 
subject’s ability to conduct normal life functions); 
 Is a congenital anomaly/birth defect; and/or 
 Constitutes an important medical event. 
Important medical events are defined as those occurrences that may not be immediately life 
threatening or result in death, hospitalization, or disability but may jeopardize the subject or 
require medical or surgical intervention to prevent one of the other outcomes listed above. 
Medical and scientific judgment should be exercised in deciding whether such an AE should be 
considered serious. 
Events not considered to be SAEs are hospitalizations for: 
 A procedure for protocol/disease-related investigations (eg, scans, endoscopy, sampling 
for laboratory tests). However, hospitalization or prolonged hospitalization for a 
complication of such procedures remains a reportable SAE. 
 Hospitalization or prolongation of hospitalization for technical, practical, or social 
reasons, in absence of an AE. 
 A procedure that is planned (ie, planned prior to starting of treatment on study) must be 
documented in the source document and the CRF. Hospitalization or prolonged 
hospitalization for a complication remains a reportable SAE. 
 Emergency outpatient treatment or observation that does not result in admission, unless 
fulfilling other seriousness criteria above. 
If an AE is considered serious, both the AE page/screen of the CRF and the SAE Report Form 
must be completed. 
For each SAE, the Investigator will provide information on severity, start and stop dates, 
relationship to IP, action taken regarding IP, and outcome. 
14.2.2 
Severity/Intensity 
For both AEs and SAEs, the Investigator must assess the severity/intensity of the event. 
Mild 
 Asymptomatic or mild symptoms; clinical or diagnostic observations only 
 Intervention not indicated 
 Activities of Daily Life (ADLs) minimally or not affected 
 No or minimal intervention/therapy may be required 
Moderate 
 Symptom(s) cause moderate discomfort 

GED-0507-34-Levo 
 
CONFIDENTIAL 
Protocol GED0507-UC-001 
 
FINAL VERSION 2.0 - PPM 24-January-2017 
Page 56 
 Local or noninvasive intervention indicated 
 More than minimal interference with ADLs but able to carry out daily social and 
functional activities. 
 Drug therapy may be required 
Severe (could be nonserious or serious) 
 Symptoms causing severe discomfort/pain 
 Symptoms requiring medical/surgical attention/intervention 
 Interference with ADLs, including inability to perform daily social and functional 
activities (eg, absenteeism and/or bed rest) 
 Drug therapy is required. 
The term “severe” is often used to describe the intensity 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 headache). This criterion is not the same as “serious,” which is 
based on subject/event outcome or action criteria associated with events that pose a threat to a 
subject’s life or functioning. 
Seriousness, not severity, serves as a guide for defining regulatory obligations. 
14.2.3 
Causality 
The Investigator must determine the relationship between the administration of IP and the 
occurrence of an AE/SAE as Not Suspected or Suspected as defined below: 
Not Suspected: 
Means a causal relationship of the AE to IP administration is unlikely or 
remote, or other medications, therapeutic interventions, or underlying 
conditions provide a sufficient explanation for the observed event. 
Suspected: 
Means there is a reasonable possibility that the administration of IP 
caused the AE. ‘Reasonable possibility’ means there is evidence to 
suggest a causal relationship between the IP and the AE. 
Causality should be assessed and provided for every AE/SAE based on currently available 
information. Causality is to be reassessed and provided as additional information becomes 
available. 
If an event is assessed as suspected of being related to a comparator, ancillary, or additional IP 
that has not been manufactured or provided by PPM SERVICES SA, the name of the 
manufacturer when reporting the event will be provided. 
14.2.4 
Duration 
For both AEs and SAEs, the Investigator will provide a record of the start and stop dates of the 
event.

CONFIDENTIAL 
Protocol GED0507-UC-001 
 
FINAL VERSION 2.0 - PPM 24-January-2017 
Page 57 
14.2.5 
Action Taken 
The Investigator will report the action taken with IP as a result of an AE or SAE, as applicable 
(eg, discontinuation, interruption, or reduction of IP, as appropriate), and report if concomitant 
and/or additional treatments were given for the event. 
14.2.6 
Outcome 
The Investigator will report the outcome of the event for both AEs and SAEs. All SAEs that have 
not resolved upon discontinuation of the subject’s participation in the study must be followed 
until recovered, recovered with sequelae, not recovered, or death (due to the SAE). 
14.3 
Abnormal Laboratory Values 
An abnormal laboratory value is considered to be an AE if the abnormality: 
 results in discontinuation from the study; 
 requires treatment, modification/interruption of IP dose, or any other therapeutic 
intervention; or 
 is judged to be of significant clinical importance. 
Regardless of severity grade, only laboratory abnormalities that fulfill a seriousness criterion 
need to be documented as an SAE. 
If a laboratory abnormality is one component of a diagnosis or syndrome, then only the diagnosis 
or syndrome should be recorded on the AE page/screen of the eCRF. If the abnormality was not 
a part of a diagnosis or syndrome, then the laboratory abnormality should be recorded as the AE. 
If possible, the laboratory abnormality should be recorded as a medical term and not simply as an 
abnormal laboratory result (eg, record thrombocytopenia rather than decreased platelets). 
14.4 
Pregnancy 
All pregnancies or suspected pregnancies occurring in either a female subject or partner of a 
male subject are immediately reportable events. 
14.4.1 
Females of Childbearing Potential 
Pregnancies and suspected pregnancies (including a positive pregnancy test regardless of age or 
disease state) of a female subject occurring while the subject is on IP, or within 28 days of the 
subject’s last dose of IP, are considered immediately reportable events. Investigational product is 
to be discontinued immediately. The pregnancy, suspected pregnancy, or positive pregnancy test 
must be reported to PPM SERVICES SA Drug Safety immediately by facsimile, or other 
appropriate method, using the Pregnancy Initial Report Form, or approved equivalent form. 
The female subject may be referred to an obstetrician-gynecologist or another appropriate 
healthcare professional for further evaluation.

CONFIDENTIAL 
Protocol GED0507-UC-001 
 
FINAL VERSION 2.0 - PPM 24-January-2017 
Page 58 
The Investigator will follow the female subject until completion of the pregnancy and must 
notify PPM SERVICES SA Drug Safety immediately about the outcome of the pregnancy (either 
normal or abnormal outcome) using the Pregnancy Follow-up Report Form, or approved 
equivalent form. 
If the outcome of the pregnancy was abnormal (eg, spontaneous abortion), the Investigator 
should report the abnormal outcome as an AE. If the abnormal outcome meets any of the serious 
criteria, it must be reported as an SAE to PPM SERVICES SA Drug Safety by facsimile, or other 
appropriate method, within 24 hours of the Investigator’s knowledge of the event using the SAE 
Report Form, or approved equivalent form. 
All neonatal deaths that occur within 28 days of birth should be reported, without regard to 
causality, as SAEs. In addition, any infant death after 28 days that the Investigator suspects is 
related to the in utero exposure to the IP should also be reported to PPM SERVICES SA Drug 
Safety by facsimile, or other appropriate method, within 24 hours of the Investigator’s 
knowledge of the event using the SAE Report Form, or approved equivalent form. 
14.4.2 
Male Subjects 
If a female partner of a male subject taking IP becomes pregnant, the male subject taking IP 
should notify the Investigator, and the pregnant female partner should be advised to call their 
healthcare provider immediately. 
14.5 
Reporting of Serious Adverse Events 
Any AE that meets any criterion for an SAE is required to be recorded via completion of the AE/ 
SAE screens of the eCRF. SAEs must be reported in the eCRF within 24 hours of the 
Investigator’s knowledge of the event. This timeline pertains to initial SAE reports as well as any 
follow-up information. If the eCRF is unavailable at the time of reporting, the Investigator must 
report the event using the appropriate paper reporting forms to comply with required timelines. 
All SAEs reported using paper forms must be entered into the eCRF as soon as the system 
becomes available. 
The Investigator is required to ensure that the data on these forms is accurate and consistent. 
This requirement applies to all SAEs (regardless of relationship to IP) that occur during the study 
(from the time the subject signs informed consent until 28 days after the last dose of IP) or any 
SAE made known to the Investigator at any time thereafter that is suspected of being related to 
IP. Serious AEs occurring prior to treatment (after signing the ICF) will be captured. 
The SAE report should provide a detailed description of the SAE and include a concise summary 
of hospital records and other relevant documents. If a subject died and an autopsy has been 
performed, copies of the autopsy report and death certificate are to be sent to PPM SERVICES 
SA Drug Safety as soon as these become available. Any follow-up data should be detailed in a 
subsequent SAE Report Form, or approved equivalent form, and sent to PPM SERVICES SA 
Drug Safety.

Page 59 
Where required by local legislation, the Investigator is responsible for informing the Institutional 
Review Board/Ethics Committee (IRB/EC) of the SAE and providing them with all relevant 
initial and follow-up information about the event. The Investigator must keep copies of all SAE 
information on file, including correspondence with PPM SERVICES SA and the IRB/EC. 
14.5.1 
Safety Queries 
Queries pertaining to SAEs will be communicated from PPM SERVICES SA Drug Safety to the 
site via facsimile or electronic mail. The response time is expected to be no more than five (5) 
business days. Urgent queries (eg, missing causality assessment) may be handled by phone.  
Expedited Reporting of Adverse Events 
For the purpose of regulatory reporting, PPM SERVICES SA Drug Safety will determine the 
expectedness of events suspected of being related to GED-0507-34-Levo based on the 
Investigator’s Brochure (IB). 
In the United States, all SUSARs will be reported in an expedited manner in accordance with the 
Code of Federal Regulations Title 21 (21 CFR) Section 312.32. 
For countries within the European Economic Area (EEA), PPM SERVICES SA or its authorized 
representative will report in an expedited manner to Regulatory Authorities and Ethics 
Committees concerned, SUSARs in accordance with Directive 2001/20/EC and the Detailed 
Guidance on collection, verification, and presentation of adverse reaction reports arising from 
clinical trials on investigational products for human use (ENTR/CT3) and also in accordance 
with country-specific requirements. 
PPM SERVICES SA or its authorized representative shall notify the Investigator of the 
following information: 
 Any AE suspected of being related to the use of IP in this study or in other studies that is 
both serious and unexpected (ie, SUSAR); 
 Any finding from tests in laboratory animals that suggests a significant risk for human 
subjects including reports of mutagenicity, teratogenicity, or carcinogenicity. 
Where required by local legislation, the Investigator shall notify his/her IRB/EC promptly of 
these new serious and unexpected AE(s) or significant risks to subjects. 
The Investigator must keep copies of all pertinent safety information on file including 
correspondence with PPM SERVICES SA and the IRB/EC (see Section 18.3 for record retention 
information).

15 DISCONTINUATIONS 
The following events are considered sufficient reasons for discontinuing a subject from the IP 
and/or from the study: 
 Lack of therapeutic effect after at least 4 weeks 
 Withdrawal of consent 
 Death 
 Lost to follow up 
 Protocol violation 
 Study terminated by sponsor 
 Pregnancy 
 Unexplained weight loss ≥ 7.5% from baseline 
The decision to discontinue a subject remains the responsibility of the treating physician, which 
will not be delayed or refused by the sponsor. However, prior to discontinuing a subject, the 
Investigator may contact the Medical Monitor and forward appropriate supporting documents for 
review and discussion. The reason for discontinuation should be recorded in the eCRF and in the 
source documents.

16 EMERGENCY PROCEDURES 
16.1 
Emergency Contact 
In emergency situations, the Investigator should contact the responsible Clinical Research 
Physician/Medical Monitor or designee by telephone at the number(s) listed on the Emergency 
Contact Information page of the protocol (after title page). 
In the unlikely event that the Clinical Research Physician/Medical Monitor or designee cannot be 
reached, please contact the global Emergency Call Center by telephone at the number listed on 
the Emergency Contact Information page of the protocol (after title page). This global 
Emergency Call Center is available 24 hours a day and 7 days a week. The representatives are 
responsible for obtaining your call-back information and contacting the on-call PPM SERVICES 
SA/CRO Medical Monitor, who will then contact you promptly. 
Note: The back-up 24-hour global emergency contact call center should only be used if you are 
not able to reach the Clinical Research Physician(s) or Medical Monitor or designee for 
emergency calls. 
16.2 
Emergency Identification of Investigational Products 
The blind must not be broken during the course of the study unless, in the opinion of the 
Investigator, it is absolutely necessary to safely treat the subject. If it is medically imperative to 
know what IP the subject is receiving, IP should be temporarily discontinued if, in the opinion of 
the Investigator, continuing IP can negatively affect the outcome of the subject’s treatment. 
The decision to break the blind in emergency situations remains the responsibility of the treating 
physician, which will not be delayed or refused by the sponsor. However, the Investigator may 
contact the Medical Monitor prior to breaking the blind to discuss unblinding, mainly in the 
interest of the subject. 
The Investigator should ensure that the code is broken only in accordance with the protocol. The 
Investigator should promptly notify the Medical Monitor of the emergency unblinding and the 
reason for breaking the blind, which should be clearly documented by the Investigator in the 
subject’s source documentation. 
Emergency unblinding should only be performed by the Investigator thorough the IVRS/IWRS 
by using an emergency unblinding personal identification number (PIN), and the Investigator 
should call IVRS/IWRS for unblinded dose information.

17 REGULATORY CONSIDERATIONS 
17.1 
Good Clinical Practice 
The procedures set out in this study protocol pertaining to the conduct, evaluation, and 
documentation of this study are designed to ensure that PPM SERVICES SA, its authorized 
representative, and Investigator abide by GCP, as described in ICH Guideline E6, and in 
accordance with the general ethical principles outlined in the Declaration of Helsinki. The study 
will receive approval from an IRB/EC prior to commencement. The Investigator will conduct all 
aspects of this study in accordance with applicable national, state, and local laws of the pertinent 
regulatory authorities. 
17.2 
Investigator Responsibilities 
Investigator responsibilities are set out in the ICH Guideline for GCP and in the local 
regulations. PPM SERVICES SA staff or an authorized representative will evaluate and approve 
all Investigators who in turn will select their staff. 
The Investigator should ensure that all persons assisting with the study are adequately informed 
about the protocol, amendments, study treatments, and study-related duties and functions. The 
Investigator should maintain a list of sub-Investigators and other appropriately qualified persons 
to whom he or she has delegated significant study-related duties. 
The Investigator is responsible for keeping a record of all subjects who sign an ICF and are 
screened for entry into the study. Subjects who fail screening must have the reason(s) recorded in 
the subject’s source documents. 
The Investigator, or a designated member of the Investigator’s staff, must be available during 
monitoring visits to review data, resolve queries, and allow direct access to subject records (eg, 
medical records, office charts, hospital charts, and study-related charts) for source data 
verification. The Investigator must ensure timely and accurate completion of eCRFs and queries. 
17.3 
Subject Information and Informed Consent 
The Investigator must obtain informed consent of a subject and/or a subject’s legal representative 
prior to any study-related procedures. 
Documentation that informed consent occurred prior to the study subject’s entry into the study 
and of the informed consent process should be recorded in the study subject’s source documents, 
including the date. The original ICF signed and dated by the study subject and by the person 
consenting the study subject prior to the study subject’s entry into the study must be maintained 
in the Investigator’s study files and a copy given to the study subject. In addition, if a protocol is 
amended and it impacts the content of the ICF, the ICF must be revised. Study subjects 
participating in the study when the amended protocol is implemented must be re-consented with 
the revised version of the ICF. The revised ICF signed and dated by the study subject and by the 
person consenting the study subject must be maintained in the Investigator’s study files and a 
copy given to the study subject.

17.4 
Confidentiality 
PPM SERVICES SA affirms the subject's right to protection against invasion of privacy and to 
be in compliance with ICH and other local regulations (whichever is most stringent). PPM 
SERVICES SA requires the Investigator to permit PPM SERVICES SA's representatives and, 
when necessary, representatives from regulatory authorities to review and/or copy any medical 
records relevant to the study in accordance with local laws. 
Should direct access to medical records require a waiver or authorization separate from the 
subject’s signed ICF, it is the responsibility of the Investigator to obtain such permission in 
writing from the appropriate individual. 
17.5 
Protocol Amendments 
Any amendment to this protocol must be approved by the PPM SERVICES SA Clinical 
Research Physician/Medical Monitor. Amendments will be submitted to the IRB/EC for written 
approval. Written approval must be obtained before implementation of the amended version 
occurs. The written signed approval from the IRB/EC should specifically reference the 
Investigator name, protocol number, study title, and amendment number(s) that is applicable. 
Amendments that are administrative in nature do not require IRB/EC approval but will be 
submitted to the IRB/EC for information purposes. 
17.6 
Institutional Review Board/Ethics Committee Review and Approval 
Before the start of the study, the study protocol, ICF, and any other appropriate documents will 
be submitted to the IRB/EC with a cover letter or a form listing the documents submitted, their 
dates of issue, and the site (or region or area of jurisdiction, as applicable) for which approval is 
sought. If applicable, the documents will also be submitted to the authorities in accordance with 
local legal requirements. 
Investigational product can only be supplied to an Investigator by PPM SERVICES SA or its 
authorized representative after documentation on all ethical and legal requirements for starting 
the study has been received by PPM SERVICES SA or its authorized representative. This 
documentation must also include a list of the members of the IRB/EC and their occupation and 
qualifications. If the IRB/EC will not disclose the names, occupations, and qualifications of the 
committee members, it should be asked to issue a statement confirming that the composition of 
the committee is in accordance with GCP. For example, the IRB General Assurance Number 
may be accepted as a substitute for this list. Formal approval by the IRB/EC should mention the 
protocol title, number, amendment number (if applicable), study site (or region or area of 
jurisdiction, as applicable), and any other documents reviewed. It must mention the date on 
which the decision was made and must be officially signed by a committee member. Before the 
first subject is enrolled in the study, all ethical and legal requirements must be met. 
The IRB/EC and, if applicable, the authorities must be informed of all subsequent protocol 
amendments in accordance with local legal requirements. Amendments must be evaluated to 
determine whether formal approval must be sought and whether the ICF should also be revised.

Data/Documents 
The Investigator must ensure that the records and documents pertaining to the conduct of the 
study and the distribution of the investigational product are complete, accurate, filed, and 
retained. Examples of source documents include: hospital records; clinic and office charts; 
laboratory notes; memoranda; subject’s diaries or evaluation checklists; dispensing records; 
recorded data from automated instruments; copies or transcriptions certified after verification as 
being accurate copies; microfiche; x-ray film and reports; and records kept at the pharmacy and 
the laboratories, as well as copies of eCRFs or compact discs random-only memory (CD-ROM). 
18.2 
Data Management 
Data will be collected via eCRF and entered into the clinical database per PPM SERVICES SA 
standard operating procedures (SOPs). This data will be electronically verified through use of 
programmed edit checks specified by the clinical team. Discrepancies in the data will be brought 
to the attention of the clinical team, and investigational site personnel, if necessary. Resolutions 
to these issues will be reflected in the database. An audit trail within the system will track all 
changes made to the data. 
18.3 
Record Retention 
Essential documents must be retained by the Investigator for a minimum of 2 years after the last 
approval of a marketing application in an ICH region and until there are no pending or 
contemplated marketing applications in an ICH region, or at least 2 years have elapsed since the 
formal discontinuation of clinical development of the IP. The Investigator must retain these 
documents for the time period described above or according to local laws or requirements, 
whichever is longer. Essential documents include but are not limited to the following: 
 Signed ICFs for all subjects; 
 Subject identification code list, screening log (if applicable), and enrollment log; 
 Record of all communications between the Investigator and the IRB/EC; 
 Composition of the IRB/EC; 
 Record of all communications between the Investigator, PPM SERVICES SA, and their 
authorized representative(s); 
 List of sub-Investigators and other appropriately qualified persons to whom the 
Investigator has delegated significant study-related duties, together with their roles in 
the study, curriculum vitae, and their signatures; 
 Copies of CRFs (if paper) and of documentation of corrections for all subjects; 
 IP accountability records; 
 Record of any body fluids or tissue samples retained; 
 All other source documents (subject records, hospital records, laboratory records, etc);

 All other documents as listed in Section 8 of the ICH consolidated guideline on GCP 
(Essential Documents for the Conduct of a Clinical Trial). 
The Investigator must notify PPM SERVICES SA if he/she wishes to assign the essential 
documents to someone else, remove them to another location, or is unable to retain them for a 
specified period. The Investigator must obtain approval in writing from PPM SERVICES SA 
prior to destruction of any records. If the Investigator is unable to meet this obligation, the 
Investigator must ask PPM SERVICES SA for permission to make alternative arrangements. 
Details of these arrangements should be documented. 
All study documents should be made available if required by relevant health authorities. The 
Investigator/institution should take measures to prevent accidental or premature destruction of 
these documents.

19 QUALITY CONTROL AND QUALITY ASSURANCE 
All aspects of the study will be carefully monitored by PPM SERVICES SA or its authorized 
representative for compliance with applicable government regulations with respect to current 
GCP and SOPs. 
19.1 
Study Monitoring and Source Data Verification 
PPM SERVICES SA ensures that appropriate monitoring procedures are performed before, 
during, and after the study. All aspects of the study are reviewed with the Investigator and the 
staff at a study initiation visit and/or at an Investigator meeting. Prior to enrolling subjects into 
the study, a PPM SERVICES SA representative will review the protocol, eCRFs, procedures for 
obtaining informed consent, record keeping, and reporting of AEs/SAEs with the Investigator. 
Monitoring will include on-site visits with the Investigator and his/her staff as well as any 
appropriate communications by mail, email, fax, or telephone. During monitoring visits, the 
facilities, investigational product storage area, eCRFs, subject’s source documents, and all other 
study documentation will be inspected/reviewed by the PPM SERVICES SA representative in 
accordance with the Study Monitoring Plan. 
Accuracy will be checked by performing source data verification that is a direct comparison of 
the entries made onto the eCRFs against the appropriate source documentation. Any resulting 
discrepancies will be reviewed with the Investigator and/or his/her staff. Any necessary 
corrections will be made directly to the CRFs or via queries by the Investigator and/or his/her 
staff. Monitoring procedures require that informed consents, adherence to inclusion/exclusion 
criteria, and documentation of SAEs and their proper recording be verified. Additional 
monitoring activities may be outlined in a study-specific monitoring plan. 
19.2 
Audits and Inspections 
In addition to the routine monitoring procedures, a GCP Quality Assurance unit exists within 
PPM SERVICES SA. Representatives of this unit will conduct audits of clinical research 
activities in accordance with PPM SERVICES SA SOPs to evaluate compliance with GCP 
guidelines and regulations. 
The Investigator is required to permit direct access to the facilities where the study took place, 
source documents, CRFs, and applicable supporting records of study subject participation for 
audits and inspections by IRB/ECs, regulatory authorities (eg, Food and Drug Administration 
[FDA], European Medicines Agency [EMA], Health Canada), and company authorized 
representatives. The Investigator should make every effort to be available for the audits and/or 
inspections. If the Investigator is contacted by any regulatory authority regarding an inspection, 
he/she should contact PPM SERVICES SA immediately.

20 PUBLICATIONS 
Study results will be communicated in full to the competent Health Authorities by the 
submission of a complete clinical study report. 
The sponsor agrees that the study results (including negative and inconclusive as well as positive 
results) can be made publicly available by the investigator publishing in peer reviewed journals, 
presenting results at scientific congresses and posting information and results on internet-based 
public registers and databases. As the sponsor agrees that the study results can be published by 
the investigators, the investigator agrees to submit any manuscript (abstract, publication, paper, 
etc.) to the sponsor before any public disclosure. This will be done in order to ensure that clinical 
study results are reported in an objective, accurate and balanced manner. The sponsor reviews 
the proposed manuscripts, before submission, within a reasonable period of time (30-90 days in 
relation with the complexity of the work). 
Selection of first authorship will be based on several considerations, including but not limited to 
study participation, contribution to the protocol development, and analysis and input into the 
manuscript, related abstracts, and presentations in a study.
