STUDY SYNOPSIS 
Protocol No.: MOT-C-201 
Study Drug: MOTREM (LR12) 
Coodinating Investigator: 
Bruno François, MD ; Inserm 1435 Clinical Investigational Center 
Title of the Study: 
Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of 3 Doses of MOTREM in Patients with Septic 
Shock. A Randomised, Double-blind, Two-Stage, Placebo Controlled Study 
Study Centre(s): 
Multi-centre, multi-national study, refer to separate list in study file 
Study Period (planned): 
• First patient first visit: Q2/2017 
• Last patient last visit: Q2/2018 
Development Phase: 
Clinical Phase IIa 
Objectives: 
Primary 
• To evaluate the safety and tolerability of MOTREM in patients with septic shock 
Secondary 
• To evaluate the effects of MOTREM exposure over up to 5 days in patients with septic shock 
• To evaluate the PK/PD and dose/PD relationship to TREM-1 pathway related markers  
• To evaluate the effect of MOTREM on transcriptomics 
• To evaluate the effect of MOTREM on clinical parameters (e.g. vasopressor doses, vasopressor-free days, 
ventilator-free days, mortality) 
Methodology 
This is a randomised, double-blind, two-stage, placebo controlled study. It consists of 2 stages with a similar 
treatment regimen, in which 0.3, 1.0 or 3.0 mg/kg/h of MOTREM is tested versus placebo. 
All patients with a diagnosis of septic shock will be considered for study participation. The applicable local 
requirements for informed consent will be followed. All potential study patients will undergo standard care 
management procedures. 
After screening for eligibility, patients will be randomised to one of the treatment arms. They will then either 
receive a 5 mg/kg loading dose of MOTREM over 15 minutes followed by a continuous i.v. infusion of 
MOTREM or a matching placebo on top of standard of care. 
Treatment with study drug must be initiated as early as possible, but no later than 24 hours after the onset of 
septic shock, defined by the start of vasopressor therapy. Blood samples for the determination of MOTREM 
(LR12) plasma concentrations and exploratory pharmacodynamic analyses will be collected before and 
throughout the treatment period. 
Patients will be treated until 12 (±2) hours after the resolution of their septic shock (defined as vasopressor 
withdrawal) with a maximum treatment duration of 5 days (120 hours). 
The survival status of patients after 28 and 90 days will be collected.  
Stage 1 is investigating multiple ascending doses of MOTREM or placebo in a sequential design in cohorts of 
4 patients (3:1 randomisation). After completion of a cohort (for up to 5 days of infusion), safety and PK data 
will be reviewed by an independent data safety monitoring board (DSMB) and the study will progress to the 
next cohort/stage.

Stage 2 investigates 3 doses of MOTREM in a randomised, balanced, parallel-group design involving up to 3 
doses of MOTREM and a placebo arm. Only dose arms of MOTREM considered to be safe and well tolerated 
during Stage 1 will be administered in Stage 2. 
Study Flowchart Stage 2 
 
Number of Patients 
The total planned number of patients is 48: twelve (12) patients in stage 1 and 36 patients in stage 2. The cohorts 
in stage 1 may be repeated according to the adaptive features of the study protocol. The total number of patients 
will not exceed 66 patients.

Statistical Methods 
Descriptive Statistics 
Demographics, baseline characteristics, and disposition data will be summarised by treatment group (Placebo, 
Dose level 1, Dose level 2 and Dose level 3).  
Safety, pharmacodynamic, pharmacokinetic and clinical data will be summarised by treatment group (Placebo, 
Dose level 1, Dose level 2 and Dose level 3), and over time.  
Qualitative variables will be presented using the number of patients, the number of missing values, the frequency 
and the percentage per modality.  
Quantitative variables will be reported using the number of patients, the number of missing values, the mean, 
the standard deviation, the median, the first and the third quartiles, the minimum and the maximum.  
Geometric means and CV may be presented for variables with a skewed distribution. 
Between groups comparisons are calculated using an independent t-test or ANOVA-test for quantitative 
variables with a parametric distribution, or Mann-Whitney-test or Kruskal Wallis-test for variables with a non-
parametric distribution.

INTRODUCTION 
6.1 
Sepsis 
For many years, the clinical features of sepsis were considered the result of an overly exuberant 
inflammatory host response. More recently, it has become apparent that infection triggers a 
much more complex, variable and prolonged host response (1,2). In general, proinflammatory 
reactions (directed at eliminating invading pathogens) are held responsible for “collateral” 
tissue damage in severe sepsis, whereas anti-inflammatory responses are implicated in the 
enhanced susceptibility to secondary infections. Key inflammatory reactions during sepsis 
include activation of leukocytes, the release of cytokines and chemokines, activation of the 
coagulation system and activation of endothelial cells (3). Inflammatory reactions are 
perpetuated in sepsis at least in part due to the release of so-called damage-associated patterns 
(or alarmins) from injured host cells (4). On the other hand, patients with sepsis demonstrate 
evidence of immune suppression, which is characterised (amongst other) by a reduced capacity 
of leukocytes to react to bacteria or bacterial products (5). Sepsis-induced immune suppression 
is characterised by loss of immune cells due to apoptosis, and held responsible for secondary 
nosocomial infections and late mortality (2,5). 
An international group of experts has recently updated the criteria for the clinical diagnosis of 
sepsis and septic shock (“Sepsis-3”) (6).  
With an incidence of approximately 150 cases of hospital treated severe sepsis per 100,000 
inhabitants in the “western” world (USA, Europe, Australia) and mortality rates of almost 30%, 
severe sepsis is a leading cause of death accounting for up to 5 million deaths worldwide (7). 
Epidemiological data in Europe confirm this information. The direct costs for the treatment 
were estimated to approx. EUR 30,000 per sepsis case, with costs higher in the US and lower 
in Europe. However, indirect costs from the loss of productivity were estimated to account for 
70-80% of cost (8). 
6.2 
Treatment of Sepsis 
The Surviving Sepsis Campaign was created in 2002 and covers severe sepsis management 
guidelines and a sepsis performance improvement program, composed by an international 
consortium of critical care, infectious disease, and emergency medicine professional societies. 
The second revision of the guidelines was published in 2013 (9). The most important 
components of the guidelines are structured in two “bundles” of care: an initial management 
bundle to be accomplished within 3-6 hours of presentation and a management bundle to be 
accomplished within 24 hours. Implementation of the bundles is associated with improved 
outcome (10). 
The principles of the initial management bundle are to provide cardiorespiratory resuscitation 
and diminish the immediate danger of the underlying infection. Resuscitation involves 
intravenous fluids, vasopressors and mechanical ventilation where needed. The initial 
management of infection entails identifying the most likely source of infection, obtaining 
cultures, instigating empiric antimicrobial therapy and pus drainage where appropriate. The 
choice of empirical antibiotic treatment depends on the site of infection, the location the 
infection was acquired (e.g. community, nursing home or hospital), medical history, and local 
microbial susceptibility patterns.  
Importantly, unlike other major illnesses, treatment for sepsis is nonspecific and restricted to 
support of failing organ functions. There are no approved drugs that specifically target sepsis. 
It is expected that sepsis will remain an important clinical problem in the future, caused by a 
combination of factors, including the ageing population, aggressive therapies for chronic

diseases (in particular malignancies) and emerging antibiotic resistance. As such, there is an 
unmet clinical need for effective therapeutic interventions in severe sepsis. 
6.3 
MOTREM for the Treatment of Septic Shock 
The Triggering Receptor Expressed on Myeloid Cells 1 (TREM-1) is an immunomodulatory 
receptor expressed on innate immune cells (11–14) The biological function of TREM-1 is the 
amplification of inflammation. In sepsis, this amplification may result in an exuberant and 
hyperactivated immune state (“genomic storm”) (15), which is responsible for the onset and 
progression of the disease.  
LR12 is a 12 amino-acid peptidic fragment derived from TREM-Like Transcript-1 (TLT-1), a 
receptor protein belonging to the TREM-1 family. LR12 can bind to (“trap”) TREM-1 ligand 
and thereby modulating the amplification of the immune response caused by the activation of 
TREM-1 both in sepsis and myocardial infarction (16,17). 
TREM-1-induced activation of several intracellular proteins involved in inflammation as well 
as cytokine production in human neutrophils and monocytes was shown to be downmodulated 
by LR12 in vitro in a dose dependent manner. In non-activated resting lymphocytes LR12 does 
not modify several intracellular signalling pathways analysed, including those involved in 
inflammation. 
As sepsis is a life-threatening disease characterised by a hyperactivated immune response, it is 
of paramount importance to consider the safety of LR12, when administered in a condition in 
which the immune system is activated. In every preclinical model of sepsis and septic shock 
studied, the administration of LR12 was associated with protective effects especially on the 
intensity of inflammation, cardiovascular system and survival: 
In animal models of peritonitis (mouse and rat), a mortality of 90 to 95% was observed within 
7 days following the onset of sepsis. The administration of LR12 significantly decreased 
mortality and sepsis related symptoms, even when administered 24 hours after the initial injury. 
Inflammatory response markers were shown to be reduced, without completely abrogating 
them. Administration of LR12 also resulted in reduction of sepsis-induced tissue abnormalities 
and showed protective effects on the cardiovascular system. In addition, the administration of 
LR12 improved bacterial clearance in mouse model of peritonitis. In a mini-pig model of 
peritonitis, the administration of LR12 led to a significant decrease of vasopressor 
(norepinephrine) administration which translates to a substantial protective effect of the 
cardiovascular system. LR12 also prevented sepsis-induced tissue abnormalities and 
dysfunctions in this model. 
During an experimental monkey endotoxemia model, the administration of LR12 attenuated 
the endotoxin-induced blood pressure decrease and release of several inflammatory cytokines 
in blood. In this model the cytokines IL-6, IL-8, TNF-α, CCL2, CCL3 and CCL4 were 
diminished to intermediate levels but not completely abrogated. 
Animal toxicity studies showed that treatment with MOTREM (formulated LR12) was safe and 
well tolerated up to doses of 140 mg/kg/day. 
In a phase I study in healthy volunteers, treatment with MOTREM was found to be safe and 
well tolerated up to the highest dose tested (6 mg/kg/h for 7h45). 
For details please refer to the current Investigator’s Brochure. 
MOTREM, therefore, represents a new class of anti-sepsis drug. The rationale for taking this 
compound into further development is the expectation that it could be an effective new anti-
sepsis therapeutic agent and the first causal treatment for sepsis.

The aim of this study in patients with septic shock is to obtain information on the safety, 
tolerability, pharmacokinetics and preliminary pharmacodynamics and efficacy of MOTREM. 
Data from this study will help to design subsequent studies in patient populations clinically and 
therapeutically relevant with this new class of compound. 
6.4 
Risk-Benefit Evaluation 
6.4.1 
Potential Benefits 
MOTREM (LR12) will be given to patients mainly for research and development purposes. 
Although a beneficial effect of MOTREM has not yet been confirmed in humans, patients 
receiving IMP may benefit from its pharmacological action.  
Over the long-term, the larger patient population with septic shock may benefit from MOTREM 
if its development will be successful. 
6.4.2 
Potential Risks 
MOTREM was found to be safe and well tolerated during preclinical safety pharmacology and 
toxicology testing (NOAEL was defined as 140 mg/kg/day for 14 days). In addition, MOTREM 
was found to be safe and well tolerated up to the highest dose tested (6 mg/kg/h for 7h45) in a 
phase I clinical study in healthy volunteers. There was no evidence of immunogenicity of 
MOTREM nor the appearance of anti-MOTREM antibodies (ADA).  
There is currently no clinical experience with MOTREM in patients with septic shock.  
As with all protein products, administration of MOTREM may result in immunogenicity. 
Immunogenicity-related risks include lack of efficacy, hyper-acute or acute reactions, delayed 
reactions or autoimmunity. LR12 is a peptide derived from a highly conserved human protein; 
it is expected to have a low immunogenic profile. An exposure to study drug of up to five days 
is not expected to result in triggering an immune response in the study patients. However, since 
the possibility of triggering an immune response against it in humans still exists, ADA 
responses will be monitored and patients will be surveyed for other manifestation of 
immunogenicity-related reactions. 
Because of its mechanism of action, MOTREM may have an impact on the immune system, 
either on immune cells or on immune responses. Since MOTREM targets activated immune 
cells in septic shock patients, the treatment with formulated LR12 may interfere with 
inflammatory/immune responses in an undesired way. However, in preclinical models, 
treatment with LR12 resulted in a diminution of proinflammatory cytokine expression and 
concentration and not in a complete abrogation of cytokine responses. In addition, LR12 
treatment resulted in a better bacterial clearance in a polymicrobial sepsis murine model. 
Patients will be carefully monitored with laboratory analysis and changes in immune parameters 
will be followed. INOTREM is maintaining a risk management plan for the clinical 
development of MOTREM, which describes potential risks of MOTREM administration, their 
monitoring and measures for mitigation. 
Other risks include infusion site associated reactions. 
6.4.3 
Benefit-Risk Assessment 
The benefit risk ratio of the study design is considered favourable because (i) throughout the 
study, all patients receive standard therapy for the treatment of their septic shock, (ii) 
progression to next dose level/next stage only after evaluation of data from previous 
groups/cohorts and approval from an independent Data Safety Monitoring Board (DSMB) and 
(iii) patients with a deterioration of their disease will be withdrawn from the study.

INVESTIGATIONAL PLAN 
8.1 
Overall Study Design and Plan Description 
This is a randomised, double-blind, two-stage, placebo controlled study. It consists of 2 stages 
with a similar treatment regimen, in which 0.3, 1.0 or 3.0 mg/kg/h of MOTREM is tested versus 
placebo. 
All patients with a diagnosis of septic shock will be considered for study participation. The 
applicable local regulations and requirements for informed consent will be followed. All 
potential study patients will undergo standard care management procedures. 
After screening for eligibility, patients will be randomised to one of the treatment arms. They 
will then either receive a 5 mg/kg loading dose of MOTREM over 15 minutes followed by a 
continuous i.v. infusion of MOTREM or a matching placebo on top of standard of care. 
Treatment with study drug must be initiated as early as possible, but no later than 24 hours after 
the onset of septic shock, defined by the start of vasopressor therapy. Blood samples for the 
determination of LR12 plasma concentrations and exploratory pharmacodynamic analyses will 
be collected before and throughout the treatment period. 
Patients will be treated until 12 (±2) hours after the resolution of their septic shock (defined as 
vasopressor withdrawal) with a maximum treatment duration of 5 days (120 (±2) hours). 
The status of patients after 28 and 90 days will be collected.  
Stage 1 is investigating multiple ascending doses of MOTREM or placebo in a sequential 
design in cohorts of 4 patients (3:1 randomisation). After completion of a cohort (for up to 5 
days of infusion), safety and PK data (limited to PK data available) will be reviewed by an 
independent DSMB and the study will progress to the next cohort/stage.  
A flowchart of the sequential dose levels in stage 1 is provided in Figure 1.

stage 2), termination or modification of the study based on the effects of the interventions under 
study. 
There is an option to have ad-hoc DSMB meetings to discuss urgent issues should the need 
arise. 
8.4.1 
Data Safety Monitoring Board (DSMB) 
An independent data safety monitoring board (DSMB) will monitor the safety of the study. The 
DSMB will comprise experts with experience in the treatment of sepsis and septic shock and 
the conduct of clinical trials in this indication. The DSMB will be responsible for: 
• Examining blinded accumulated safety and PK data, with no formal statistical analysis 
performed, in order to make recommendations for the progression of the study to next 
dose (stage 1) or progression from stage1 to stage 2.  
• Reviewing serious adverse events (SAEs) and toxicity data 
• Reviewing the general progress of the clinical study with regard to accrual/withdrawals 
or drop-out rates and clinical study conduct. 
Where necessary, DSMB members may have access to unblinded safety data for one or more 
patients; however, no members of the study team (at INOTREM, at the Contract Research 
Organisation [CRO] or the sites) will have access to unblinded data until after database lock is 
declared. In case unblinded data needs to be handled or analysed before database lock, these 
tasks will be performed by persons independent from the study team. 
The DSMB will provide recommendations for stopping or continuing the study based on safety 
results. The roles, responsibilities, and operating procedures of the DSMB will be formally 
defined in a DSMB charter which will be developed in consultation with DSMB members. 
8.4.2 
Data Requirements 
After each cohort, the DSMB will assess the minimum safety, tolerability and PK data required 
prior to dose escalation/progression. Prior to each DSMB meeting, an interim safety report will 
be prepared for that cohort presenting the relevant safety and tolerability data.  
The following data will be required: (i) all SAE data (ii) available AE data and (iii) available 
PK data. 
8.5 
Rationale for Study, Doses and Control Groups 
8.5.1 
Rationale for Conducting Study 
The rationale for taking MOTREM into further development is the expectation that this 
compound could be an effective new anti-sepsis therapeutic agent. This study represents the 
first time that MOTREM will be administered to patients with septic shock. Data from this 
study will help to design subsequent therapeutic studies with this new class of compounds. 
Consequently, this study intends to confirm the safety, tolerability and PK obtained in the 
healthy volunteer study. In addition, it will explore the pharmacodynamic effects of MOTREM. 
8.5.2 
Rationale and Justification for Placebo Control 
During this study, all patients will be treated with standard therapy. On top of this therapy, 
MOTREM or placebo will be added. No medications will be withdrawn for the purpose of this 
study. Placebo was chosen as a comparator in order to investigate the safety and 
pharmacodynamics of MOTREM in this study population.

8.5.3 
Rationale for Dose Levels  
There will be a loading dose of 5 mg/kg administered within 15 minutes in all dose groups. The 
maintenance dose levels planned for this study (0.3, 1.0 and 3.0 mg/kg) do represent the 
expected therapeutic window as determined from in vitro and animal studies. Fifteen-minutes 
loading doses of 0.5 to 5mg/kg and maintenance doses ranging from 0.03 mg/kg/h to 6 mg/kg/h 
were found to be safe and well tolerated in the completed phase I study (MOT-C-104) in healthy 
volunteers. In addition, this dose range is fully covered by preclinical animal toxicity and safety 
pharmacology studies. In preclinical studies, MOTREM has been safely administered to 
cynomolgous monkeys during 14 days at a dose of 5.8 mg/kg/h and for a total cumulated dose 
of 140 mg/kg/day and 1960 mg/kg during the whole period.  
In this study, patients will start receiving 0.3 mg/kg/h for a maximum of 5 days (7.2 mg/kg/day 
and 36 mg/kg for the whole period) and, if safe, dose will be escalated to a maximum of 3 
mg/kg/h for up to 5 days (72 mg/kg/day and 360 mg/kg for the whole period). 
8.5.4 
Rationale for Exposure Time  
The rationale for administering MOTREM up to 5 days is that immune initial inflammatory 
loop is activated during this period (15). Indeed sTREM-1 circulating levels are very high 
during these first days, in particular in patients with high mortality, and is probably a sign of 
TREM-1 pathway activation and thus an exacerbation of inflammatory responses (18). Stage 1 
of the study consists of an ascending dose design and escalation to the next dose level will occur 
after review of accumulated safety data by the DSMB. 
9 
SELECTION OF PATIENTS 
9.1 
Number and Source of Patients 
A total of 48 patients is planned. There will be 12 patients in stage 1 (4 per dose level) and 36 
patients in stage 2 (9 per dose level). No formal sample size calculation was performed. The 
number of patients was chosen on the basis of similar studies investigating the safety, 
tolerability and pharmacokinetics of a drug product. In stage 1, the patients will be treated in 
three sequential cohorts with ascending dose levels of 4 patients each. Stage 2 of the study has 
a parallel-group design, where three dose levels of MOTREM will be compared to placebo. 
Patients admitted to the participating intensive care units (ICUs) for septic shock will be 
screened at admission for eligibility. The eligibility criteria are identical between the two stages 
of the study. 
The maximum number of patients according to the adaptive features of the study protocol will 
not exceed 66 patients, as specified below: 
• Each cohort in stage 1 can be repeated once for the collection of additional safety data 
• In each cohort in stage 1, one patient not completing 24 hours of study drug infusion 
will be replaced  
At sites, who are conducting more than one clinical trial competing for the same patient 
population, a selection bias should be avoided. Random allocation of patients with the diagnosis 
to the different trials is an acceptable method for the minimisation of such bias and is 
recommended (19). A respective procedure should be in place at these sites.

Central Review of Patient Eligibility Prior to Inclusion 
Before a patient can be included, the investigator or delegate must discuss the diagnosis of 
septic shock and other eligibility criteria by phone with the clinical coordinating centre (CCC) 
of the study. Only patients approved by the CCC can be included in the study. The CCC will 
document all decisions in writing. The CCC operational procedures will be documented in a 
separate charter.  
The CCC for the study is reachable by phone 24/7 under the following phone number: 
+32 (2) 764 27 80

9.5 
Withdrawal of Patients 
The investigator will withdraw a patient from the study (i.e. from any further study medication 
or study procedure) for one or more of the following reasons: 
• At the request of the patient or legal representative (withdrawal of consent) 
• If, in the investigator’s opinion, continuation of the study would be detrimental to the 
patient’s well-being 
• Use of/need for a prohibited medication which in the opinion of the Sponsor or 
Investigator may jeopardise the study results or represent a risk to the participant 
• Major violation of the protocol 
• Is withdrawn from the study upon the request of Sponsor, including if Sponsor 
terminates the study. 
As far as possible, all examinations scheduled for the final study day (EOS) must be performed 
on all patients who receive the investigational product but do not complete the study according 
to the protocol. In any case, the respective case report form (CRF) section entitled “End of 
Study” as well as survival status at days 28 and 90 must be completed. 
In all cases, the reason for and date of withdrawal must be recorded in the CRF and in the 
patient’s medical records. The patient must be followed up to establish whether the reason was 
an AE, and, if so, this must be reported in accordance with the procedures in section 13 on page 
42. 
The investigator must make every effort to contact patients lost to follow-up. Attempts to 
contact such patients must be documented in the patient’s records (e.g., times and dates of 
attempted telephone contact, receipt for sending a registered letter). At least two documented 
attempts to contact the patient must be made before a patient can be considered lost to follow-
up.  
9.5.1 
Replacement of Patients 
In stage 1 of the study, patients not completing 24 hours of study drug infusion will be replaced. 
For replaced patients, the same randomisation scheme will be utilised to ensure distribution of 
patients to dose levels as planned. No more than one patient per cohort will be replaced. 
In stage 2 of the study, patients will not be replaced.  
9.5.2 
Withdrawal of Blood and Urine Samples 
As stated in the informed consent form and according to national provisions, the patient may 
request all previously retained identifiable samples to be destroyed.  
9.6 
Patients of Reproductive Potential 
Since MOTREM is a peptide derived from an endogenous human protein, adverse effects to 
unborn offspring is considered unlikely. Since the testing of reproductive toxicity is not yet 
complete, the most stringent precautions for the inclusion of females of childbearing potential 
will be applied according to CTFG guidance (20) will be applied. All female patients will have 
a serum pregnancy test performed before enrolment into the study. Since the patients will be 
hospitalised in an ICU during treatment with IMP, contraceptive measures and additional 
pregnancy tests are not considered required. Since the half-life of MOTREM is very short 
(approx. 2 minutes), pregnancy testing beyond the stay in the ICU is not considered required.

10 STUDY AND CONCOMITANT TREATMENTS 
10.1 Investigational Medicinal Product (IMP)  
MOTREM is prepared as a stable lyophilised product in L50 type I glass vials containing 400 
mg of free base lyophilised LR12 peptide in sodium citrate and arginine buffer at pH 5.5. The 
powder is to be solubilised with 40 mL of saline solution for injection to yield a clear and 
colourless solution of MOTREM at 10 mg/mL. Table 4 shows the composition of MOTREM 
in vials and as reconstituted solution. IMP will be stored under appropriate conditions in a 
reasonably secure +2 to +8°C refrigerator placed in a room of restricted access.

10.2 Placebo 
The placebo used in this study will be a saline solution (i.e. NaCl 0.9%). Since placebo and 
IMP have both a clear appearance as formulated LR12 is diluted in saline solution, this assures 
blinding of the study treatment. The saline solution will be either provided by the site or by the 
sponsor. 
10.3 Doses and Treatment Regimen 
Single doses of MOTREM (LR12) or matching placebo are planned to be administered i.v. as 
detailed in Table 5 and Table 6.

MOTREM or matching placebo will be administered by the investigator or delegate and the 
details of dosing will be recorded in the CRF.  
The study drugs will be dispensed by the pharmacy staff at the clinical study site. The pharmacy 
staff or a dedicated unblinded person independent from the study team will be responsible for 
assembly and labelling of dosing containers according to randomisation schedules and assigned 
dose level. The amount/ volume of study drug to be administered will be determined based on 
the assigned dose level for a particular cohort. The procedure for preparing the study drugs and 
the volume to be prepared for each individual patient dose will be detailed in a Pharmacy 
Worksheet. 
Detailed instructions for dose administration is included in the Study Operations Manual 
(SOM). 
10.4 Labelling of Study Drug  
The labelling of the study drugs will be in compliance with Good Manufacturing Practice 
(GMP) specifications, as described in The Rules Governing Medicinal Products in the European 
Union, Volume 4, Annex 13, Investigational Medicinal Products, and any other or local 
applicable regulations. 
Sample label(s) will be submitted to the competent regulatory authorities according to the 
submission requirements. 
10.5 Drug Accountability  
The designated pharmacy staff at the clinical study site will maintain accurate records of receipt 
and the condition of all study drugs, including dates of receipt. In addition, accurate records 
will be kept by the pharmacy staff of when and how much study drug is dispensed and used by 
each patient in the study. Any reason for deviation from the protocol dispensing regimen must 
also be recorded.  
Drug accountability records and inventory will be available for verification by the Sponsor or 
designee. At the completion of the study, there will be a final reconciliation of all study drugs.   
Study drug must not be used for any purpose other than the present study. Remaining study 
drug will be returned to the Sponsor or its agent or destroyed at the clinical study site according 
to applicable regulations and only after receipt of written authorisation from the Sponsor. 
10.6 Blinding and Procedures for Unblinding the Study 
10.6.1 Methods for Ensuring Blinding 
The study will be conducted in a double-blind fashion, whereby patients and clinical study site 
staff are blinded to study drug assignment. 

INOTREM S.A. 
CONFIDENTIAL 
Study Protocol MOT-C-201 Version 4.1 
 
Page 33 of 59 
 
 
The pharmacy staff or any other dedicated person preparing the investigational products will 
not be blinded to study drug assignment and will be responsible for the blinding of the study 
drug. During the study, the randomisation codes will be kept in the site's clinical trials 
pharmacy, accessible to the pharmacy personnel or any other dedicated person only. Upon 
completion of the study, after the database lock and after the blind is revealed, the randomisation 
list will be filed in the Study Master File. 
10.6.2 Methods for Unblinding a Patient 
Individual randomisation code for each randomised patient will be available from electronic 
Case Report Form (eCRF). The investigator may request unblinding of a patient’s treatment 
assignment mainly in the case of an emergency, when knowledge of the study treatment is 
essential for the appropriate clinical management or welfare of the patient. 
In the event of an emergency, an unblinding tool will be accessible from patient overview in 
the eCRF and allow to know for each patient his study drug assignment.  
Unblinding should only be considered for the safety of the patient. If unblinding is deemed 
necessary by the investigator, the investigator or designee can unblind the patient’s treatment 
allocation using a specific function in eCRF. The investigator or designee must note the date, 
time and reason for unblinding and inform the sponsor of unblinding as soon as practicably 
possible. 
The patient whose treatment has been unblinded will continue in the study. 
10.7 Prior and Concomitant Medications/Procedures 
Medication taken by the patients on entry to the study or at any time during the study in addition 
to the investigational product, are regarded as concomitant treatments and must be documented 
in the appropriate sections of the eCRF. 
Parenteral nutrition, vitamin supplements and stool softener will not be recorded in the eCRF. 
Relevant previous treatments taken within 24 hours before start of treatment must also be 
documented in the CRF. 
Concomitant medications will be recorded in the eCRF until 3 days after end of infusion (EOI).  
Concomitant medications related to AEs (corrective drug required) should be recorded until 
D28. 
Before enrolment into the study, all patients should receive standard of care, including fluid 
therapy, as recommended in the current version of the guidelines issued by the Surviving Sepsis 
Campaign (9).  
10.7.1 Allowed and Not-Allowed Medications and Procedures  
All treatments and procedures required for the treatment of the patient’s illness are permitted. 
The following concomitant treatments are not permitted during the treatment phase of this study 
(i.e. study drug infusion): 
• Bolus glucocorticoid treatment exceeding 300mg of hydrocortisone or equivalent per 
day for a maximum of three days 
11 STUDY PROCEDURES AND SCHEDULE 
An overview on study procedures and schedule is provided in the flowcharts in Figure 1, Figure

12 STUDY METHODOLOGY 
12.1 Medical History 
All relevant medical history (diagnoses) available from patient records will be collected in the 
eCRF. 
12.2 Previous and Concomitant Therapies 
All treatments taken by the patients on entry to the study or at any time during the study in 
addition to the investigational product, are regarded as concomitant treatments and must be 
documented on the appropriate pages of the eCRF. 
Concomitant medications will be recorded in the eCRF until 3 days after end of infusion (EOI).  
Concomitant medications related to AEs (corrective drug required) should be recorded until 
D28. 
Relevant previous treatments taken within 24 hours before the study must also be documented 
in the eCRF. 
12.3 APACHE II Score 
The Acute Physiology and Chronic Health Evaluation II score is a severity-of-disease 
classification system (21). It is generally applied within 24 hours of admission of a patient to 
an intensive care unit (ICU). An integer score from 0 to 71 is computed based on measurements 
of:  
• AaDO2 or PaO2 (depending on FiO2) 
• Temperature (rectal)

• Mean arterial pressure 
• pH arterial 
• Heart rate 
• Respiratory rate 
• Sodium (serum) 
• Potassium (serum) 
• Creatinine 
• Haematocrit 
• White blood cell count 
• Glasgow Coma Scale 
Higher scores correspond to more severe disease and a higher risk of death.  
Patients eligible for the study must not have an APACHE II Score of ≥ 34 or <14. 
12.4 Vital Signs 
Systolic and diastolic blood pressure and heart rate will be documented in the eCRF. 
12.5 SOFA Score 
The SOFA (sequential organ failure assessment) score is a scoring system to determine the 
extent of a person's organ function or rate of failure. It is based on six different scores, one each 
for the respiratory, cardiovascular, hepatic, coagulation, renal and neurological systems (22). 
It will be calculated daily between screening and day 5 and at day 28 according to the following:

12.6 Electrocardiographic (ECG) Measurements 
12-lead ECGs will be recorded daily at the time-points described in the study plan in Table 1 
on page 23. Copies of the ECG printouts will be collected by the sponsor. 
12.7 Physical Examination, Height and Weight 
Physical examinations will be performed as detailed in the Study Plan (Table 1). 
A full physical examination includes an assessment of the following: eyes, ears, nose, throat, 
cardiovascular, respiratory, musculoskeletal, venous system, gastro-intestinal, lymphatic, 
dermatological and neurological system. 
A brief physical examination will be symptom oriented and will not include specific parameters 
of full physical examination.  
Height will be measured in centimetres and weight in kilograms. Where possible, measurements 
should be taken with patients wearing light clothing and without shoes using calibrated scales 
for all measurements. BMI will be calculated from the height and weight.

12.9 Sepsis Related Clinical Events 
Clinical events related to severe sepsis or sepsis complications will be collected. The following 
events will be considered clinical events related to severe sepsis or sepsis complications: 
• Death related to severe sepsis, that is, related to severe sepsis or a sequela of sepsis 
based on the interpretation of the investigator. 
• Cardiovascular events: the need for vasoactive drugs, hypotension. 
• Respiratory events: decreased PaO2/FiO2, mechanical ventilation, hypoxia, acute 
respiratory distress syndrome, acute lung injury, or respiratory failure. 
• Hepatic events: hepatic injury or liver dysfunction that leads to an increase from baseline 
in the serum level of bilirubin or other LFTs. 
• Renal events: renal failure, renal insufficiency, or renal injury that leads to an increase 
from baseline in serum creatinine. 
• Hematologic/coagulation events: coagulopathy, disseminated intravascular coagulation, 
thrombocytopenia, or thrombocytosis. 
• Systemic inflammatory response syndrome related criteria: tachypnea, hypopnea, 
leukocytosis, leukopenia, hypothermia, hyperthermia, tachycardia, or bradycardia. 
12.10 Mortality Assessment 
If a patient dies during the course of the study (time of informed consent to day 90 follow-up), 
the date and time of death will be documented. If possible, the cause of death will be 
documented.  
12.11 Study Drug Infusion 
The beginning and end of study of each drug infusion will be documented in the eCRF. 
12.12 Duration of ICU Stay 
The date and time of ICU discharge will be collected. This data will be collected to the extent 
available in source data and analysed post-hoc (see section 15.5). 
12.13 Laboratory Tests 
12.13.1 Local Laboratory Tests 
The following laboratory tests will be performed at the clinical sites and the results will be 
transcribed into the clinical database

Arterial Blood Gases  
Partial pressure of arterial oxygen (PaO2) and carbon dioxide (PaCO2) and pH will be 
documented at the time points specified in Table 2 on page 25. 
12.13.2 Centralised Laboratory Tests 
All centralised laboratory tests and procedures are described in detail in a separate manual. 
Biomarkers and RNA Profiles 
Blood samples for the assessment of biomarkers and RNA profiles will be collected 
throughout the study according to Table 2 on page 25. Details for sampling requirements, 
storage and shipment to the respective laboratories are described in the SOM. 
Pharmacokinetic Assessments 
For timing of individual samples refer to the Study Plan (Table 1and Table 2). The date and 
time of collection will be recorded on the appropriate eCRF. 
PK Blood Samples: Venous blood samples for the determination of concentrations of LR12 
(active ingredient of MOTREM) in plasma will be taken at the times presented in the Study 
Schedule (Table 1 and Table 2).  
All sample handling procedures, including the time of each sample collection, the time of 
placement into frozen storage (at the end of the sample workup), will be documented in detail 
in the laboratory manual. The procedures and materials used, e.g. collection and storage tubes, 
were examined prior to any analytical measurements as part of the analytical method validation, 
to rule out any possible interference with the analyte. 
Immunogenicity 
The presence of anti-drug antibodies (ADA) will be assessed as described in Table 1 and Table 
2. A venous blood sample will be collected for evaluation of anti-drug antibody presence for 
all patients at the selected time-points. Further details and sample analysis will be described in 
the laboratory manual.  
12.13.3 Plasma Sample for Retention 
A plasma sample for future exploratory analyses of biomarkers as described in Table 1 and 
Table 2 will be retained for all patients. The specimen will be used to achieve the following 
objectives: 
• To study the association of biomarkers with efficacy of MOTREM treatment, 
adverse events or disease progression 
• To increase knowledge and understanding of the septic shock disease biology 
All biomarker samples will be destroyed no later than 5 years after the Clinical study report has 
been completed. However, the storage period will be in accordance to the ICF approved by the 
ethics committee and applicable laws. 
All biomarker specimen will be subject to the confidentiality standards described in section 
17.5. 
12.13.4 Blood Sample for Pharmacogenetic Analysis 
Certain polymorphisms in the gene coding for the TREM-1 and related genes could have an 
effect on the safety and efficacy of MOTREM. Therefore, one small blood sample for the future 

INOTREM S.A. 
CONFIDENTIAL 
Study Protocol MOT-C-201 Version 4.1 
 
Page 42 of 59 
 
 
exploratory analysis of these polymorphisms will be collected as described in Table 1 and Table 
2. The total volume of blood sampling will remain unchanged as specified in section 12.12.5 
below. 
All biomarker samples will be destroyed no later than 5 years after the Clinical study report has 
been completed. However, the storage period will be in accordance to the ICF approved by the 
ethics committee and applicable laws.  
All specimens will be subject to the confidentiality standards described in section 17.5. 
The participation in this part of the study is voluntary and covered by a separate ICF. 
12.13.5 Volume of Blood Sampling 
Total blood volume sampled during the study in addition to standard care for each patient will 
be approximately 160 mL.  
The total volume of blood that will be drawn from each patient in this study will be further 
specified in study operations manual. The actual amount withdrawn may be different per patient 
in case samples need to be repeated for technical reasons but will not exceed 250 mL. 
12.13.6 Analysis and Storage of Blood Samples 
All blood samples will be collected, processed, and reported as necessary for the purpose of the 
trial according to the study protocol. 
Some of the blood samples will be analysed in the hospital’s laboratory and are part of the 
patient’s routine care. When the results are available, the samples will be destroyed according 
to the hospital’s regulations. 
Some of the blood samples will be sent to external laboratories for analysis. To maintain 
confidentiality, these samples will be coded and will not contain any personal identifying 
information.  
Two serum samples will be stored for the purpose of studying specific characteristics predicting 
whether individual patients have a better or worse chance to respond to the treatment. Since 
these markers are still under investigation, we may need to do further research with these 
samples once the trial is finished. The samples will be kept in a secure place for a up to 5 years 
and will be destroyed when the investigated results become available. Unused blood samples 
from external laboratories described above, may be used for exploratory analyses and will be 
treated accordingly. 
One blood sample for exploratory pharmacogenetic analyses will be kept in a secure place, for 
a up to 5 years and will be destroyed when the investigated results become available. The blood 
samples for DNA analysis will be double coded (two independent coding steps). 
13 ADVERSE EVENTS 
13.1 Adverse Events 
Safety will be determined by an evaluation of physical examination, vital signs, ECG 
parameters, laboratory tests and by the occurrence of Adverse Events (AEs). 
Adverse event (AE): Any untoward medical occurrence in a patient or clinical study subject 
administered a medicinal product and which does not necessarily have a causal relationship 
with this treatment. Events occurring prior to the first administration are part of baseline 
information. 

INOTREM S.A. 
CONFIDENTIAL 
Study Protocol MOT-C-201 Version 4.1 
 
Page 43 of 59 
 
 
An adverse event (AE) can therefore be any unfavourable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease temporally associated with the use of an 
investigational medicinal product, whether or not considered related to the investigational 
medicinal product. 
Adverse reaction (AR): All untoward and unintended responses to an IMP related to any dose 
administered. 
All adverse events judged by either the reporting investigator or sponsor as having a reasonable 
suspected causal relationship to an investigational medicinal product are qualified as adverse 
reactions. The expression reasonable causal relationship means that there is evidence or 
argument to suggest a causal relationship. 
Multiple signs or symptoms: If an AE consists of several signs or symptoms that can be 
represented by one single syndrome or diagnosis, the syndrome or diagnosis will be recorded 
in the CRF as the AE instead of the individual signs or symptoms.  
Worsening: Signs, symptoms, syndromes or diagnoses present before the first administration 
of the IMP will be considered as AEs if they worsen after the start of the IMP. 
AE collection: The condition of the patients will be monitored throughout the study from the 
time of signed Informed Consent up to the end of the study (day 28). The investigator will 
collect the AEs reported spontaneously, observed, or elicited in response to a non-leading 
question (for example, "How have you been feeling since we last asked you?"). The investigator 
will record all AEs in the source records and the eCRF. 
Study specific definition: 
Clinical events related to severe sepsis or sepsis complications are recorded on the appropriate 
eCRFs (see section 12.9). When serious, these clinical events are exempt from serious adverse 
event reporting, unless the investigator deems the event to be related to the administration of 
the study drug. The following events will be considered clinical events related to severe sepsis 
or sepsis complications: 
• Death related to severe sepsis, that is, related to severe sepsis or a sequela of sepsis 
based on the interpretation of the investigator. 
• Cardiovascular events: the need for vasoactive drugs, hypotension. 
• Respiratory events: decreased PaO2/FiO2, mechanical ventilation, hypoxia, acute 
respiratory distress syndrome, acute lung injury, or respiratory failure. 
• Hepatic events: hepatic injury or liver dysfunction that leads to an increase from 
baseline in the serum level of bilirubin or other LFTs. 
• Renal events: renal failure, renal insufficiency, or renal injury that leads to an increase 
from baseline in serum creatinine. 
• Hematologic/coagulation 
events: 
coagulopathy, 
disseminated 
intravascular 
coagulation, thrombocytopenia, or thrombocytosis. 
• Systemic inflammatory response syndrome related criteria: tachypnea, hypopnea, 
leukocytosis, leukopenia, hypothermia, hyperthermia, tachycardia, or bradycardia. 
AE rating: 
The assessment of intensity of an AE will be made using the following general categorical 
descriptors: 
Mild 
No interference with the patient’s daily activities and does not 
require mandatory corrective/symptomatic treatment 

INOTREM S.A. 
CONFIDENTIAL 
Study Protocol MOT-C-201 Version 4.1 
 
Page 44 of 59 
 
 
Moderate 
Moderate interference with the patient’s daily activities and/or 
requires minimal medical intervention or corrective treatment 
required 
Severe 
Major and unacceptable interference with the patient’s daily 
activities 
and 
requires 
mandatory 
corrective/symptomatic 
treatment, possible hospitalisation 
 
The investigator should use clinical judgment in assessing the intensity of events not directly 
experienced by the patient (e.g., laboratory abnormalities). 
The causal relationship of AEs will be rated as either related or unrelated to the IMP.  
The causal relationship of a SAE to the IMP will be rated as follows: 
Unrelated 
Clearly and incontrovertibly due only to extraneous causes, and 
does not meet criteria listed under unlikely, possible or probable. 
Unlikely 
Does not follow a reasonable temporal sequence from 
administration of the IMP, or is most likely related to another 
etiology than the trial drug such as the patient’s clinical state, 
environmental factors or other therapies. 
Possible 
Follows a reasonable temporal sequence from administration of the 
IMP, and/or a causal relationship cannot be excluded and remains 
likely. 
Probable 
Good reason (such as clear-cut temporal association with 
improvement on cessation of the IMP or reduction in dose, or 
reappears upon (accidental) rechallenge, or follows a known pattern 
of response to the IMP) and sufficient documentation to assume a 
causal relationship. 
 
The action taken with the IMP for an AE will be rated as: product withdrawn, dosing 
interrupted, dose not changed, not applicable. AEs requiring therapy will be treated with 
recognised standards of medical care to protect the health and the well-being of the patient. 
The outcome of an AE will be rated as recovered, recovering, not recovered, recovered with 
sequelae, fatal or unknown. The investigator will follow up any AE until it is resolved or until 
the medical condition of the patient is stable. All relevant follow-up information will be 
collected. For AEs that are ongoing at the last visit, the investigator will make thorough efforts 
to document the outcome. 
13.2 Serious Adverse Events (SAE) 
13.2.1 Definitions 
Serious Adverse Event: Any untoward medical occurrence that at any dose: 
• Results in death, 
• Is life-threatening, 
• Requires inpatient hospitalisation or prolongation of existing hospitalisation,  
• Results in persistent or significant disability or incapacity, 
• Is a congenital anomaly or birth defect 
• Is an important medical event 

INOTREM S.A. 
CONFIDENTIAL 
Study Protocol MOT-C-201 Version 4.1 
 
Page 45 of 59 
 
 
Death: The death of a patient enrolled in a clinical study is per se not an event, but an outcome. 
Any AE resulting in a fatal outcome must be fully documented and reported, including situation 
for which the death occurred after treatment end, and regardless of the causality relationship 
between the death and the IMP. The cause of the death is usually the AE. If the cause cannot 
be determined, the case will be considered an unexplained death. 
Life-threatening: Any AE that places the patient, in the view of the initial reporter 
(investigator), at immediate risk of death from the AE as it occurred, i.e. it does not include an 
AE that, had it occurred in a more severe form, might have caused death. 
Disability: A substantial disruption of a person's ability to conduct normal life functions. 
Important medical event: An important medical event that may not result in death, be life-
threatening, or require hospitalisation may be considered as a SAE when, based upon 
appropriate medical judgement, it may jeopardise the patient and may require medical or 
surgical intervention to prevent one of the outcomes listed in the definition. The concept 
includes AEs which suggest a significant hazard, contraindication or precaution for use, 
occurrence of malignancy or development of drug dependency or drug abuse. 
13.2.2 Other Events to be Treated as Serious Adverse Events 
Exposure to drug during pregnancy: In principle, pregnancy and the lactation period are 
exclusion criteria for clinical studies involving investigational drugs, which are not directly 
related to the respective conditions. In the event of a pregnancy occurring during the course of 
this particular study, the patient should be withdrawn from study, but closely followed-up 
during the entire course of the pregnancy and postpartum period.  
Investigational Product Complaints: Pharmaceutical technical complaints associated with 
the investigational product must be reported immediately. The same reporting timelines as for 
SAEs apply. 
13.2.3 Reporting of Serious Adverse Events 
If any SAE occurs, the investigator will take appropriate action immediately and will strive to 
identify the causes of the events. 
SAEs will be notified by the Investigator to Stragen Services, acting on behalf of the Sponsor, 
as soon as possible, i.e. within 24 hours from first knowledge by e-mail or fax to: 
E-mail: InotremPV@stragen.fr 
Phone: +33 (0)  4 78 42 95 26 
Fax : +33 (0)  4 78 42 55 71 
Stragen Services acknowledges the receipt of the SAE information by email to the 
investigational site within one working day. In the absence of email acknowledging the receipt 
or in case of issue in sending the fax or email, the investigator shall contact Stragen Services 
by any means for ensuring the receipt of SAE information at the earliest opportunity. 
Any follow-up information will be reported to Stragen Services as soon as it becomes known, 
with the same process and timelines as described here above for initial reports.  Photocopies of 
results, consultant report(s), a summary of the outcome of the reaction and the Investigator's 
opinion of IMP relationship to the SAE will accompany the SAE form if and when available. 
The Sponsor will also perform an evaluation of the seriousness, causality and expectedness of 
all SAEs. All SAEs judged by either the Investigator or the Sponsor as having a reasonable 
suspected causal relationship to an IMP (i.e. probably or possibly related) will qualify as serious 

INOTREM S.A. 
CONFIDENTIAL 
Study Protocol MOT-C-201 Version 4.1 
 
Page 46 of 59 
 
 
adverse reactions. If the Sponsor disagrees with the Investigator’s causality assessment, both 
the opinion of the Investigator and the Sponsor are provided with the report. 
All reported SAEs will be included in the INOTREM SA pharmacovigilance database. 
Suspected unexpected serious adverse reactions (SUSARs) are AEs which have a reasonable 
possibility to be related to an IMP and are both unexpected (i.e. the nature or severity is not 
expected from the information provided in the investigator’s Brochure) and serious. SUSARs 
are subject to immediate (ANSM)/within 7 days expedited reporting to the Competent 
Authorities and Ethics Committees. 
SUSARs will be notified to the Competent Authorities and to the relevant ECs by Stragen 
Services immediately (ANSM)/within 7 days (other Competent Authorities) (for fatal and life-
threatening SUSARs) or 15 days (all other SUSARs), with follow-up information in the 
following 8 days. The decision on the reportability will be made by the sponsor.  
Annual safety reporting to the Competent Authorities and the Ethics Committees will be in 
agreement with ICH guideline E2F “Note for guidance on development safety update reports 
(DSUR)”. 
In addition, any other safety issue, such as any new fact including information which may alter 
the current benefit–risk assessment of the IMP or the concerned clinical trial, which may lead 
to changes in the use of the IMP, in the conduct of the clinical trial, or of its related documents 
including the study protocol, or which may lead to suspend or terminate this clinical trial or 
similar researches, which may alter the current benefit–risk assessment of the IMP will be 
reported by the Sponsor (or delegate) immediately (France) or on an expedited basis to Health 
Authorities, Ethics Committees and the Investigators. 
The specific reporting modalities implemented by French Decree number 2016-1537 dated 16 
November 2016 for clinical trials involving healthy/patient volunteers are applicable for all 
parts of this study. 
13.3 Recording of Adverse Events and Follow-Up 
All (serious and non-serious) adverse events detected by the Investigator or delegates, or 
spontaneously notified by the patient at each visit/examination must be reported on the 
respective section of the eCRF. 
The following information should be reported for each adverse event, whether or not it can be 
attributed to trial drug: 
• description of adverse event 
• date of onset/date of disappearance 
• characteristics of the event (seriousness, intensity) 
• actions taken (treatment required or dose adjustments must be reported in the CRF) 
• outcome 
• relationship with trial drug (causality assessment) and/or study participation 
All adverse events must be documented and followed up until the event is either resolved 
or a satisfactory explanation is found, or the investigator considers it medically justifiable 
to terminate the follow-up. 
Any AEs that are unresolved at the patient's last AE assessment in the study (i.e. at the end of 
study visit) are to be followed up by the Investigator for as long as medically indicated. 
INOTREM SA retains the right to request additional information for any patient with ongoing 
AE(s)/SAE(s) at the end of the study, if judged necessary. 

INOTREM S.A. 
CONFIDENTIAL 
Study Protocol MOT-C-201 Version 4.1 
 
Page 47 of 59 
 
 
Findings and values related to physical examinations and measurements of ECG, vital signs, 
(temperature, blood pressure, and heart rate) and laboratory parameters will be defined as AEs 
if they are considered clinically relevant deteriorations compared with screening values, as 
judged by the investigator. 
13.4 Period of Observation 
Adverse events (serious and non-serious) will be recorded and reported to the sponsor from 
the time of written informed consent to the end of study (Day 28). 
Relevant changes to patient’s status will be recorded until day 90. 
14 QUALITY ASSURANCE AND QUALITY CONTROL 
Monitoring and auditing procedures developed or endorsed by the Sponsor will be followed in 
accordance with GCP guidelines. Direct access to the on-site study documentation and medical 
records must be ensured. 
14.1 Monitoring and Source Data Verification 
All aspects of the study will be carefully monitored by the sponsor, or designee, for compliance 
with applicable government regulations with respect to Good Clinical Practice (GCP) and 
current standard operating procedures. 
The monitoring of this study will be performed by the Sponsor’s Monitor(s) or a designee in 
accordance with the principles of GCP as laid out in the International Conference on 
Harmonisation (ICH) “Good Clinical Practice: Consolidated Guideline”. 
The clinical monitor, as a representative of the Sponsor, has an obligation to follow the study 
closely. In doing so, the monitor will visit the Investigator and site periodically as well as 
maintain frequent telephone and letter contact. The monitor will maintain current personal 
knowledge of the study through observation, review of study records and source documentation, 
and discussion of the conduct of the study with the Investigator and staff. Further details will 
be described in the SOM. 
14.2 On-Site Audits and Inspections 
Domestic and foreign regulatory authorities, the EC or IRB, and an auditor authorised by the 
Sponsor may request access to all source documents, eCRFs, and other study documentation 
for on-site audit or inspection. Direct access to these documents must be guaranteed by the 
investigator, who must provide support at all times for these activities. Medical records and 
other study documents may be copied during audit or inspection provided that patient names 
are removed on the copies to ensure confidentiality. 
In case the study site is patient to an inspection by regulatory bodies, the investigator will inform 
the sponsor promptly after the notification of such inspection. 
15 STATISTICAL CONSIDERATIONS 
The analysis of study data will be detailed in a separate statistical analysis plan (SAP). Some 
of the analyses may be reported separately as specified in the SAP. 
15.1 Statistical Methods 

INOTREM S.A. 
CONFIDENTIAL 
Study Protocol MOT-C-201 Version 4.1 
 
Page 48 of 59 
 
 
15.1.1 General Considerations 
The analysis will be computed with SAS Version 9.4 (Copyright© 2013 by SAS Institute Inc., 
Cary, NC, USA). 
Unless otherwise specified, baseline is defined as the last planned assessment prior to first 
dosing and no subgroup analysis is currently planned. 
Missing safety, pharmacodynamic, pharmacokinetic and clinical data will not be replaced and 
will be treated as missing from summary and statistical analyses.  
Unless otherwise specified, all treatment comparisons will be two-sided and significance will 
be assessed at the 5% level. 
All safety, pharmacokinetic, pharmacodynamic and clinical data will be summarised by 
treatment group (Placebo, Dose level 1, Dose level 2 and Dose level 3), and visit, as appropriate.  
Qualitative variables will be presented using the number of patients, the number of missing 
values, the frequency and the percentage per modality.  
Quantitative variables will be reported using the number of patients, the number of missing 
values, the mean, the standard deviation, the median, the first and the third quartiles, the 
minimum and the maximum.  
Between groups comparisons are calculated using an independent t-test or ANOVA-test for 
quantitative variables with a parametric distribution, or Mann-Whitney test or Kruskal Wallis-
test for variables with a non-parametric distribution. 
Data is tested for normality using Kolmogorov-Smirnov-test. 
15.1.2 Analysis Sets 
Safety analyses will be conducted on the safety analysis set, including all patients who received 
at least one dose of the study drug.  
Pharmacodynamic (PD) analyses will be conducted on the PD analysis set, including all patients 
who received at least one dose of study drug, had at least one post-baseline PD assessment and 
no protocol deviation with a major effect on PD results.  
Pharmacokinetic (PK) analyses will be conducted on the PK analysis set, including all patients 
who received at least one dose of MOTREM, had at least one post-baseline PK assessment and 
no protocol deviation with a major effect on PK results. 
15.1.3 Endpoints 
Safety and tolerability will be the primary endpoint and it will be monitored during the course 
of the study as specified below: 
Safety and Tolerability Parameters  
• Vital signs: systolic (SBP) and diastolic (DBP) blood pressure, heart rate, and body 
temperature. 
• ECG (12-lead ECG)  
• Safety laboratory tests: haematology, coagulation, plasma biochemistry.  
• Presence of anti-LR12 antibodies  
• Adverse events: from screening until study completion.  
Secondary endpoints include the following: 

INOTREM S.A. 
CONFIDENTIAL 
Study Protocol MOT-C-201 Version 4.1 
 
Page 49 of 59 
 
 
Pharmacokinetics 
Plasma concentrations of LR12 will be measured by a validated LC-MS/MS assay and analysed 
using non-compartmental methods to obtain estimates of the PK parameters.  
Pharmacodynamics (exploratory) 
The concentration profiles of biomarkers (sTREM-1,  immune and vascular related biomarkers) 
over time and biomarker mRNA levels will be analysed. 
Clinical Parameters 
• Resolution of organ dysfunction (SOFA score total and individual domains) 
• Vasopressor use 
• Invasive mechanical ventilation 
• Renal support 
• Time until shock reversal defined as cessation of vasopressor support for 24 hours 
• Mortality at day 28 and day 90 
Safety and tolerability will be the primary endpoint and in addition, the exposure of MOTREM 
will be analysed. The biomarker concentration profiles over time and the area under the 
concentration (AUC) curves will be analysed as secondary PD variables. 
The MOTREM concentration profile over time and the main derived PK parameters will be 
analysed as PK endpoints.  
The endpoints and their analysis will be further specified in the statistical analysis plan (SAP). 
15.1.4 Baseline Characteristics and Patient Disposition 
Baseline characteristics (medical history, previous therapies, APACHE II Score, physical 
examination and serum pregnancy test), demographics and disposition data will be summarised 
by treatment group (Placebo, Dose level 1, Dose level 2 and Dose level 3). 
15.1.5 Safety Analyses 
Adverse events will be coded using the MedDRA dictionary version 18.1 or higher. Treatment 
emergent adverse events (events start after the first dose of investigational treatment or events 
present prior the administration of investigational treatment and worsened during the study 
(increased in severity)) will be classified by primary system organ class, preferred term and 
treatment group. Separate summaries will be performed for study medication related events, 
death, serious adverse events, adverse events leading to discontinuation of study medication 
and other adverse events of interest. 
Other safety parameters that will be assessed include safety laboratory parameters 
(haematology, coagulation, biochemistry, arterial blood gases etc), vital signs (SBP, DBP, heart 
rate and body temperature), ECG and exposure of MOTREM. The parameters will be listed by 
treatment group (Placebo, Dose level 1, Dose level 2 and Dose level 3), patient and visit and 
summarised using standard descriptive statistics. All abnormal values will be identified in 
patient data listings. Changes from baseline will be described. 
PD Analyses: Pharmacodynamic data will be listed by treatment, patient, and visit/time. 
Summary statistics will be provided by treatment and visit/time. Geometric means and CV will 
be presented for the primary and secondary PD endpoints. 
PD endpoints will be compared between treatments with an ANOVA on logs. Each MOTREM 
dose group will be compared to placebo with a contract t-test at the 2-sided 10% level.

PK Analyses: Observed MOTREM serum concentrations will be summarised by treatment and 
corresponding time when sampling occurred. Derived PK parameters will be summarised by 
treatment. 
Clinical Analyses: Several clinical parameters as the clinical events related to sepsis and its 
complications, the SOFA score total and each sub-score (respiratory, cardiovascular, hepatic, 
coagulation, renal and neurological system), the vasopressor use, the mechanical ventilation 
and intubation will be described by treatment group and visit. Standard descriptive statistics 
will be used.  
15.2 Determination of Sample Size 
A formal sample size calculation was not performed for the primary objective of the study. 
Instead, the sample size 48 patients overall (N=12 for each dose level) was chosen to provide 
sufficient data for this pilot study of MOTREM in patients with septic shock. This is in line 
with recommendations for sample size of pilot studies (23). 
As this is an exploratory study no adjustments for multiplicity will be employed. 
15.3 Randomisation Methods 
The randomisation lists will be performed by Ascopharm Statistician using SAS software 
Version 9.4 (Copyright© 2013 by SAS Institute Inc., Cary, NC, USA) with the procedure 
“PROC PLAN” before the start of the study. 
Randomisation lists produced will be implemented into the randomisation module of the Ennov 
Clinical© software (V7.5 or higher). 
The first randomisation list for the stage 1 will be created with a minimum of 3 randomisation 
blocs of 4 i.e. 12 patients. Each sequential cohort (0.3, 1.0 and 3.0 mg/kg/h of MOTREM) will 
contain 4 patients (3 active and 1 placebo). Patient satisfying eligibility criteria will be 
randomised in a 3:1 ratio per cohort to the treatments as specified below: 
• MOTREM  
• Placebo 
The second randomisation list for the stage 2 will be created with a minimum of 9 randomisation 
blocs of 4 i.e. 36 patients. Each dose group will contain 9 patients. Patient satisfying eligibility 
criteria will be randomised in a 1:1 ratio to the treatments as specified below: 
• Dose level 1 
• Dose level 2 
• Dose level 3 
• Placebo 
For security, the two randomisation lists will be extended over the number of patients initially 
planned. For example, for the stage 1, three extra cohorts of 4 patients each will be planned as 
cohorts could be repeated once. 
A randomisation list will be provided to the site’s pharmacy, who is in charge of blinding and 
labelling of the treatments.  
15.4 Interim Analysis 
One unblinded interim analysis of complete 28-Day data is planned, after the end of study visit 
(D28) is complete for all patients, while the study is still ongoing. Some exploratory biomarker 
and ADA data may not be included in the interim analysis. 

INOTREM S.A. 
CONFIDENTIAL 
Study Protocol MOT-C-201 Version 4.1 
 
Page 51 of 59 
 
 
The study will be unblinded after the last subject completes the EOS visit and the interim 
database is available, including cleaned and locked data up to EOS visit (except possibly some 
of the biomarkers/ADA results). All parties (sponsor, investigators and subjects) may be 
unblinded at the time of this interim analysis. 
The purpose of this interim analysis is to gather preliminary information in order to trigger 
possible external business decisions. The study will not be stopped early on the basis of this 
interim review. 
Details for this interim analysis will be specified in the statistical analysis plan (SAP). The SAP 
will be finalised prior to unblinding. 
15.5 
Retrospective Collection of Data and Post-hoc Analysis 
For exploratory analyses of nangibotide's efficacy for the treatment of septic shock, additional 
data will be collected on the following parameters: 
• SOFA score: For all surviving patients, SOFA scores will be collected up to day 5. The 
purpose of this is to replace data that have been treated as missing in the original 
analysis. 
• Duration of ICU stay: This is expected to provide efficacy data on a clinically relevant 
endpoint. 
These data have not been collected in the original eCRF. They will be collected from source 
data at sites to the extent available.  
The analysis of this data will follow the principles of the main analysis and will be further 
specified in a separate statistical analysis plan. The results will be reported separately. 
16 ETHICAL AND LEGAL ASPECTS 
16.1 Good Clinical Practice (GCP) 
This protocol complies with the principles of the World Medical Assembly (Helsinki 1964) and 
subsequent amendments (24) and in keeping with local regulations. 
16.2 Informed Consent 
The informed consent is a process by which a patient voluntarily confirms his/her willingness 
to participate in a clinical study. It is the responsibility of the investigator or delegate to obtain 
written informed consent from patients. All consent documentation must be in accordance with 
applicable regulations and GCP. Each patient is requested to sign the Informed Consent Form 
(ICF) after they have received and read the written patient information and received an 
explanation of what the study involves, including but not limited to: the objectives, potential 
benefits and risk, inconveniences, and the patient’s rights and responsibilities. Signed ICFs 
must remain on file and must be available for verification by Study Monitors at any time. 
Another signed original of the ICF must be given to the patient or the patient’s legally 
authorised representative.  
In case of incapacitated patients, the following procedures will be followed for obtaining 
informed consent according to applicable regulations: 
• Informed consent will be obtained from the patient’s family or legal representative 
• If the family cannot be reached, an emergency informed consent procedure will be 
followed 

INOTREM S.A. 
CONFIDENTIAL 
Study Protocol MOT-C-201 Version 4.1 
 
Page 52 of 59 
 
 
• As soon a patient is no longer incapacitated, informed consent to continue participation 
will be obtained from the patient at that time. 
The sponsor will be provided with a copy of the Ethics Committee (EC) approved consent 
forms, and a copy of the EC written approval, prior to the start of the study. 
16.3 Study Protocol Amendments 
Any variation in procedure from that specified in the final clinical study protocol may lead to 
the results of the clinical study being questioned and in some cases rejected. Any proposed 
clinical study protocol change must therefore be discussed and approved with/by the Sponsor 
and submitted for EC and regulatory authority approval. Any relevant clinical study protocol 
change should be documented in a clinical study protocol amendment. Once the study has 
started, amendments should be made only in exceptional cases.  
16.4 Approval of the Clinical Study Protocol and Amendments 
Before the start of the study, the clinical study protocol, patient information leaflet and informed 
consent form, and any other appropriate documents will be submitted to the EC. The appropriate 
documents will also be submitted to the Competent Authorities (CAs), and any other bodies 
involved in the review of the clinical trial, in accordance with local legal requirements. As 
required by local regulation or by the EC, the sponsor or investigator will also submit the 
financial arrangements for the study or other financial interests of the investigator in the 
investigational drug or Sponsor company to the EC. 
Before the first patient is enrolled in the study, all ethical and legal requirements must be met. 
If applicable, the ECs and CAs must be informed of all subsequent amendments and 
administrative changes, in accordance with local legal requirements. Amendments must be 
evaluated to determine whether formal approval must be sought and whether the patient 
information leaflet and informed consent form should also be revised. 
The (coordinating) investigator or sponsor’s delegate must keep a record of all communication 
with the ECs. This also applies to any communication between the (coordinating) investigator 
or sponsor’s delegate and the authorities. 
16.5 Ongoing Information for Ethics Committee 
Unless otherwise instructed by the EC or local law, the sponsor or the investigator must submit 
to the EC: 
• Information on SUSAR’s from the investigator’s site and other sites as required, as 
soon as possible and within the legal timelines 
• Expedited safety reports from the Sponsor, as soon as possible 
• Periodic reports on the progress of the study, where required 
• Deviations from the protocol, where required 
16.6 Protocol Adherence and Delegation of Duties 
The investigator and delegates must adhere to the study protocol. The investigator will be 
responsible for enrolling only those patients who have met the eligibility criteria of the CSP. 
The investigator will be required to sign an Investigator Agreement to confirm acceptance and 
willingness for themselves and delegates to comply with the study protocol. 
The investigator must ensure that all persons assisting with the trial are adequately qualified, 
informed about the protocol, any amendments to the protocol, the study treatments and their 

INOTREM S.A. 
CONFIDENTIAL 
Study Protocol MOT-C-201 Version 4.1 
 
Page 53 of 59 
 
 
trial-related duties and functions. The investigator should maintain a list of subinvestigators and 
other appropriately qualified persons, to whom significant trial related duties were delegated. 
16.7 Liability and Insurance 
The sponsor will maintain liability and insurance provisions for patients and investigators 
according to legal requirements and applicable regulations. These are available in separate 
agreements. 
16.8 Discontinuation of the Study 
The study must be discontinued at the site on completion. 
The whole study may be discontinued in the event of any of the following: 
• Determination of unexpected, significant, or unacceptable risk to patients  
• Medical or ethical reasons affecting the continued performance of the study 
• Difficulties in the recruitment of patients 
• Plans to modify, suspend, or discontinue the development of the study drug 
Completion or premature termination of the study will be reported by the Sponsor to the 
regulatory agency and by the Sponsor or investigator to the EC as required by local regulation 
or by the EC. 
Furthermore, the Sponsor or the investigator has the right to close the study site at any time. As 
far as possible, premature discontinuation should occur after mutual consultation. 
Study materials must be returned, disposed of or retained as directed by the Sponsor. 
16.9 Record Retention 
The investigator must obtain approval in writing from the Sponsor before destruction of any 
records, and must document any change of ownership. 
Study records should be retained until at least 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 investigational product. However, these documents should be 
retained for a longer period if required by the applicable regulatory requirements or by an 
agreement with the Sponsor. It is the responsibility of the Sponsor to inform the 
investigator/institution as to when these documents no longer need to be retained. Patient 
identification codes have to be retained according to ICH GCP or for at least 15 years after the 
completion or discontinuation of the trial whatever is the longest period in time. 
If an investigator leaves an investigational site, the responsibility for archiving of all study 
related records has to be transferred to another person (e.g. other investigator). The Sponsor has 
to be informed about any change in responsibility. 
17 DOCUMENTATION AND USE OF STUDY FINDINGS 
17.1 Case Report Forms 
An eCRF for the study will be available online, on a secure website. Only the investigators, or 
the sub-investigators/designee, are authorised to entry data in the eCRF. They are identified 
using a login and a password as an electronic signature. At the beginning of the study, a login 
will be allocated to each site staff who will be asked to identify himself/herself by a personal 
password. 

INOTREM S.A. 
CONFIDENTIAL 
Study Protocol MOT-C-201 Version 4.1 
 
Page 54 of 59 
 
 
The investigator, the sub-investigator or its designated representative will create a new eCRF 
for each patient having signed the informed consent and randomised. Any additional 
information on data entry process will be included in a data handling procedure. The 
investigator must check that all the data is accurate and correct. If any information is not 
applicable, missing (not determined) or unknown, the investigator will record "NA", "ND" or 
“UK” in the appropriate place. After a page/screen is completed, the investigator has to validate 
it (lock action). This action prevents from modification of the data after entry (data are 
“frozen”). 
If a data that has already been validated in the eCRF has to be corrected, the initial value, the 
identity of the person who modify the data, the date and the reason of the modification are 
tracked in an audit trial file, linked to the eCRF, not accessible/not modifiable to/by the 
investigators. When, the correction is done; the investigator has to validate it. 
Each opened case report form must be completed. After final verification by the monitor and 
resolution of possible queries, the data are definitively not modifiable by the investigator. 
17.2 Clinical Database 
Data Management will create the database under Oracle (V10.2.04 or higher) and the eCRF 
entry screens. 
The eCRF application will be accessible by connecting on a dedicated and secure website using 
Clinsight Online module. Each user will connect by using personal identifier / password. 
The Data Manager will write the Data Handling Manual (DHM) which describes the various 
data management steps, the database structure (name and format of the items) and the annotated 
eCRF, and the validation plan. 
The investigator, sub-investigators or its designated representative will enter the data for each 
patient on online eCRF application. The data will be extracted from the ORACLE database and 
formatted as SAS files (V9.4).  
The Data Manager will program the consistency checks defined in the validation plan. These 
checks will result in the production of Electronic Data Clarification Forms (eDCFs). The 
investigator or designated representative will directly answer to these eDCFs on the eCRF 
application.  
Adverse events will be coded using MedDRA dictionary, and concomitant treatment will be 
coded using WHO-DRUG dictionary version 2015-3 or higher. 
At the end of the validation process, the Data Manager will produce listings which describe all 
protocol deviations. The status of these deviations (minor or major) will be discussed during 
the pre-analysis review, and the analysis population will be defined. 
At the end of the data management process, the database will be frozen and the SAS files will 
be sent to INOTREM SA according to the Data transfer process. 
17.3 Use of Study Findings 
All information concerning the product as well as any matter concerning the operation of the 
Sponsor, such as clinical indications for the drug, its formula, methods of manufacture and other 
scientific data relating to it, that have been provided by the Sponsor and are unpublished, are 
confidential and must remain the sole property of the Sponsor. The investigator will agree to 
use the information only for the purposes of carrying out this study and for no other purpose 
unless prior written permission from the Sponsor is obtained. 
The Sponsor has full ownership of the original eCRFs completed as part of the study. 

INOTREM S.A.

By signing the clinical study protocol, the investigator agrees that the results of the study may 
be used for the purposes of national and international registration, publication, and information 
for medical and pharmaceutical professionals. The authorities will be notified of the 
investigator’s name, address, qualifications, and extent of involvement. 
All materials, documents and information supplied by the Sponsor to the investigator, and all 
materials, documents and information prepared or developed in the course of the study to be 
performed under this protocol, shall be the sole and exclusive property of the Sponsor. 
17.4 Clinical Study Report 
The Sponsor will document the findings of the study in a clinical study report final report 
according to applicable legal requirements and regulations. 
As required by local regulation or by the EC or IRB, a summary of the clinical study will be 
submitted by the Sponsor to the regulatory authorities and by the Sponsor or investigator to 
the EC or IRB. 
The following exploratory study assessments will be reported separately: 
• RNA transcriptomics 
• Pharmacogenetics 
17.5 Confidentiality 
After patients have consented to take part in the study, their medical records and the data 
collected during the study will be reviewed by the sponsor and/or its representatives. These 
records and data may, in addition, be reviewed by the following: (i) independent auditors who 
validate the data on behalf of the sponsor; (ii) national or local regulatory authorities.  
Although patients will be known by a unique number, their date of birth will also be collected 
and used to assist the sponsor to verify the accuracy of the data, for example, that the results of 
study assessments are assigned to the correct patient. The results of this study containing the 
unique number, and relevant medical information including ethnicity may be recorded and 
transferred to and used in other countries throughout the world, which may not afford the same 
level of protection that applies within the EU. The purpose of any such transfer would be to 
support regulatory submissions made by the sponsor in such countries. 
17.6 Publications 
INOTREM is dedicated to support free exchange of relevant scientific information. The study 
will be registered in a public clinical trial database. By signing the final protocol, the principal 
investigator agrees to keep all information and results concerning the study and the 
investigational product confidential as long as the data remain unpublished. The Sponsor will 
document the results of the clinical trial in a study report. Prior to any submission, all 
manuscripts/abstracts must be presented to the Sponsor for possible comments. 
If requested, the investigator will withhold publication to allow for filing a patent application 
or taking such other measures as the Sponsor deems appropriate to establish and preserve its 
proprietary rights.

APPENDIX 1: RECOMMENDATIONS FOR FLUID THERAPY 
The following measures of fluid therapy are recommended according to the current treatment 
guideline of the Surviving Sepsis Campaign (9): 
1. Crystalloids as the initial fluid of choice in the resuscitation of severe sepsis and septic 
shock  
2. Against the use of hydroxyethyl starches for fluid resuscitation of severe sepsis and 
septic shock  
3. Albumin in the fluid resuscitation of severe sepsis and septic shock when patients 
require substantial amounts of crystalloids  
4. Initial fluid challenge in patients with sepsis-induced tissue hypoperfusion with 
suspicion of hypovolemia to achieve a minimum of 30 mL/kg of crystalloids (a portion 
of this may be albumin equivalent). More rapid administration and greater amounts of 
fluid may be needed in some patients  
5. Fluid challenge technique be applied wherein fluid administration is continued as long 
as there is hemodynamic improvement either based on dynamic (e.g., change in pulse 
pressure, stroke volume variation) or static (e.g. arterial pressure, heart rate) variables
